Medicare Program; Proposed Changes to the Hospital Outpatient 
Prospective Payment System and Calendar Year 2006 Payment Rates

AGENCY: Centers for Medicare & Medicaid Services (CMS), HHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This proposed rule would revise the Medicare hospital 
outpatient prospective payment system to implement applicable statutory 
requirements and changes arising from our continuing experience with 
this system and to implement certain related provisions of the Medicare 
Prescription Drug, Improvement, and Modernization Act (MMA) of 2003. In 
addition, the proposed rule describes proposed changes to the amounts 
and factors used to determine the payment rates for Medicare hospital 
outpatient services paid under the prospective payment system. This 
proposed rule would also change the requirement for physician oversight 
of mid-level practitioners in critical access hospitals (CAHs). These 
changes would be applicable to services furnished on or after January 
1, 2006.

I. Background

A. Legislative and Regulatory Authority for the Hospital Outpatient 
Prospective Payment System

    When the Medicare statute was originally enacted, Medicare payment 
for hospital outpatient services was based on hospital-specific costs. 
In an effort to ensure that Medicare and its beneficiaries pay 
appropriately for services and to encourage more efficient delivery of 
care, the Congress mandated replacement of the reasonable cost-based 
payment methodology with a prospective payment system (PPS). The 
Balanced Budget Act of 1997 (BBA) (Pub. L. 105-33), enacted on August 
5, 1997, added section 1833(t) to the Social Security Act (the Act) 
authorizing implementation of a PPS for hospital outpatient services. 
The Medicare, Medicaid, and SCHIP Balanced Budget Refinement Act of 
1999 (BBRA) (Pub. L. 106-113), enacted on November 29, 1999, made major 
changes that affected the hospital outpatient PPS (OPPS). The Medicare, 
Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 
(BIPA) (Pub. L. 106-554), enacted on December 21, 2000, made further 
changes in the OPPS. Section 1833(t) of the Act was also amended by the 
Medicare Prescription Drug, Improvement, and Modernization Act of 2003 
(MMA), Pub. L. 108-173, enacted on December 8, 2003. (Discussion of 
provisions related specifically to the CY 2006 OPPS is included in 
sections V. and VII. of this proposed rule.) The OPPS was first 
implemented for services furnished on or after August 1, 2000. 
Implementing regulations for the OPPS are located at 42 CFR part 419.
    Under the OPPS, we pay for hospital outpatient services on a rate-
per-service basis that varies according to the ambulatory payment 
classification (APC) group to which the service is

[[Page 42677]]

assigned. We use Healthcare Common Procedure Coding System (HCPCS) 
codes (which include certain Current Procedural Terminology (CPT) 
codes) and descriptors to identify and group the services within each 
APC group. The OPPS includes payment for most hospital outpatient 
services, except those identified in section I.B. of this proposed 
rule. Section 1833(t)(1)(B)(ii) of the Act provides for Medicare 
payment under the OPPS for certain services designated by the Secretary 
that are furnished to inpatients who have exhausted their Part A 
benefits or who are otherwise not in a covered Part A stay. Section 611 
of Pub. L. 108-173 provided for Medicare coverage of an initial 
preventive physical examination, subject to the applicable deductible 
and coinsurance, as an outpatient department service, payable under the 
OPPS. In addition, the OPPS includes payment for partial 
hospitalization services furnished by community mental health centers 
(CMHCs).
    The OPPS rate is an unadjusted national payment amount that 
includes the Medicare payment and the beneficiary copayment. This rate 
is divided into a labor-related amount and a nonlabor-related amount. 
The labor-related amount is adjusted for area wage differences using 
the inpatient hospital wage index value for the locality in which the 
hospital or CMHC is located.
    All services and items within an APC group are comparable 
clinically and with respect to resource use (section 1833(t)(2)(B) of 
the Act). In accordance with section 1833(t)(2) of the Act, subject to 
certain exceptions, services and items within an APC group cannot be 
considered comparable with respect to the use of resources if the 
highest median (or mean cost, if elected by the Secretary) for an item 
or service in the APC group is more than 2 times greater than the 
lowest median cost for an item or service within the same APC group 
(referred to as the ``2 times rule''). In implementing this provision, 
we use the median cost of the item or service assigned to an APC group.
    Special payments under the OPPS may be made for new technology 
items and services in one of two ways. Section 1833(t)(6) of the Act 
provides for temporary additional payments or ``transitional pass-
through payments'' for certain drugs, biological agents, brachytherapy 
devices used for the treatment of cancer, and categories of medical 
devices for at least 2 but not more than 3 years. For new technology 
services that are not eligible for pass-through payments and for which 
we lack sufficient data to appropriately assign them to a clinical APC 
group, we have established special APC groups based on costs, which we 
refer to as ``APC cost bands.'' These cost bands allow us to price 
these new procedures more appropriately and consistently. Similar to 
pass-through payments, these special payments for new technology 
services are also temporary; that is, we retain a service within a new 
technology APC group until we acquire adequate data to assign it to a 
clinically appropriate APC group.

B. Excluded OPPS Services and Hospitals

    Section 1833(t)(1)(B)(i) of the Act authorizes the Secretary to 
designate the hospital outpatient services that are paid under the 
OPPS. While most hospital outpatient services are payable under the 
OPPS, section 1833(t)(1)(B)(iv) of the Act excluded payment for 
ambulance, physical and occupational therapy, and speech-language 
pathology services, for which payment is made under a fee schedule. 
Section 614 of Pub. L. 108-173 amended section 1833(t)(1)(B)(iv) of the 
Act to exclude OPPS payment for screening and diagnostic mammography 
services. The Secretary exercised the broad authority granted under the 
statute to exclude from the OPPS those services that are paid under fee 
schedules or other payment systems. Such excluded services include, for 
example, the professional services of physicians and nonphysician 
practitioners paid under the Medicare Physician Fee Schedule (MPFS); 
laboratory services paid under the clinical diagnostic laboratory fee 
schedule; services for beneficiaries with end-stage renal disease 
(ESRD) that are paid under the ESRD composite rate; and services and 
procedures that require an inpatient stay that are paid under the 
hospital inpatient prospective payment system (IPPS). We set forth the 
services that are excluded from payment under the OPPS in Sec.  419.22 
of the regulations.
    Under Sec.  419.20 of the regulations, we specify the types of 
hospitals and entities that are excluded from payment under the OPPS. 
These excluded entities include Maryland hospitals, but only for 
services that are paid under a cost containment waiver in accordance 
with section 1814(b)(3) of the Act; critical access hospitals (CAHs); 
hospitals located outside of the 50 States, the District of Columbia, 
and Puerto Rico; and Indian Health Service hospitals.

C. Prior Rulemaking

    On April 7, 2000, we published in the Federal Register a final rule 
with comment period (65 FR 18434) to implement a prospective payment 
system for hospital outpatient services. The hospital OPPS was first 
implemented for services furnished on or after August 1, 2000. Section 
1833(t)(9) of the Act requires the Secretary to review certain 
components of the OPPS not less often than annually and to revise the 
groups, relative payment weights, and other adjustments to take into 
account changes in medical practice, changes in technology, and the 
addition of new services, new cost data, and other relevant information 
and factors. Since implementing the OPPS, we have published final rules 
in the Federal Register annually to implement statutory requirements 
and changes arising from our experience with this system. For a full 
discussion of the changes to the OPPS, we refer readers to these 
Federal Register final rules.\1\

---------------------------------------------------------------------------

    On November 15, 2004, we published in the Federal Register a final 
rule with comment period (69 FR 65681) that revised the OPPS to update 
the payment weights and conversion factor for services payable under 
the calendar year (CY) 2005 OPPS on the basis of claims data from 
January 1, 2003 through December 31, 2003, and to implement certain 
provisions of Pub. L. 108-173. In addition, we responded to public 
comments received on the January 6, 2004 interim final rule with 
comment period relating to Pub. L. 108-173 provisions that were 
effective January 1, 2004, and finalized those policies. Further, we 
responded to public comments received on the November 7, 2003 final 
rule with comment period pertaining to the APC assignment of HCPCS 
codes identified in Addendum B of that rule with the new interim (NI) 
comment indicators; and public comments received on the August 16, 2004 
OPPS proposed rule (69 FR 50448).
    Subsequent to publishing the November 15, 2004 final rule with 
comment period, we published a correction of final rule with comment 
period on December 30, 2004 (69 FR 78315). This document corrected 
technical errors that appeared in the November 15, 2004 final rule with

comment period. It also provided additional information about the CY 
2005 wage indices for the OPPS that was not published in the November 
15, 2004 final rule with comment period.

D. APC Advisory Panel

1. Authority of the APC Panel
    Section 1833(t)(9)(A) of the Act, as amended by section 201(h) of 
the BBRA of 1999, requires that we consult with an outside panel of 
experts to review the clinical integrity of the payment groups and 
weights under the OPPS. The Advisory Panel on Ambulatory Payment 
Classification (APC) Groups (the APC Panel), discussed under section 
I.D.2. of this preamble, fulfills this requirement. The Act further 
specifies that the APC Panel will act in an advisory capacity. This 
expert panel, which is to be composed of 15 representatives of 
providers subject to the OPPS (currently employed full-time, not 
consultants, in their respective areas of expertise), reviews and 
advises us about the clinical integrity of the APC groups and their 
weights. The APC Panel is not restricted to using our data and may use 
data collected or developed by organizations outside the Department in 
conducting its review.
2. Establishment of the APC Panel
    On November 21, 2000, the Secretary originally signed the charter 
establishing the APC Panel. The APC Panel is technical in nature and is 
governed by the provisions of the Federal Advisory Committee Act 
(FACA), as amended (Pub. L. 92-463). Since its initial chartering, the 
Secretary has twice renewed the APC Panel's charter: On November 1, 
2002, and on November 8, 2004. The renewed charter indicates that the 
APC Panel continues to be technical in nature; is governed by the 
provisions of the FACA with a Designated Federal Official (DEO) to 
oversee the day-to-day administration of the FACA requirements and to 
provide to the Committee Management Officer all committee reports for 
forwarding to the Library of Congress; may convene up to three meetings 
per year; and is chaired by a Federal official who also serves as a CMS 
medical officer.
    Originally, in establishing the APC Panel, we solicited members in 
a notice published in the Federal Register on December 5, 2000 (65 FR 
75943). We received applications from more than 115 individuals who 
nominated either colleagues or themselves. After carefully reviewing 
the applications, we chose 15 highly qualified individuals to serve on 
the APC Panel. Because of the loss of four APC Panel members due to the 
expiration of terms of office on March 31, 2004, we published a Federal 
Register notice on January 23, 2004 (69 FR 3370) that solicited 
nominations for APC Panel membership. From the 24 nominations that we 
received, we chose four new members. Six members' terms expired on 
March 31, 2005; therefore, a Federal Register notice was published on 
February 25, 2005, requesting nominations to the APC Panel. We received 
only 13 nominations before the nomination period closed on March 15, 
2005. Therefore, we extended the deadline for nominations to May 9, 
2005, and announced the extension in the Federal Register on April 8, 
2005 (70 FR 18028). The entire APC Panel membership and information 
pertaining to it, including Federal Register notices, meeting dates, 
agenda topics, and meeting reports are identified on the CMS Web site: 
http://www.cms.hhs.gov/faca/apc/apcmem.asp.

3. APC Panel Meetings and Organizational Structure
    The APC Panel first met on February 27, February 28, and March 1, 
2001. Since that initial meeting, the APC Panel has held six subsequent 
meetings, with the last meeting taking place on February 23 and 24, 
2005. (The APC Panel did not meet on February 25, 2004, as announced in 
the meeting notice published on December 30, 2004, (69 FR 78464).) 
Prior to each of these biennial meetings, we published a notice in the 
Federal Register to announce each meeting and, when necessary, to 
solicit and announce nominations for APC Panel membership. For a more 
detailed discussion about these announcements, refer to the following 
Federal Register notices: December 5, 2000 (65 FR 75943), December 14, 
2001 (66 FR 64838), December 27, 2002 (67 FR 79107), July 25, 2003 (68 
FR 44089), December 24, 2003 (68 FR 74621), August 5, 2004 (69 FR 
47446), and December 30, 2004 (69 FR 78464).
    During these meetings, the APC Panel established its operational 
structure that, in part, includes the use of three subcommittees to 
facilitate its required APC review process. Currently, the three 
subcommittees are the Data Subcommittee, the Observation Subcommittee, 
and the Packaging Subcommittee. The Data Subcommittee is responsible 
for studying the data issues confronting the APC Panel and for 
recommending viable options for resolving them. This subcommittee was 
initially established on April 23, 2001, as the Research Subcommittee 
and reestablished as the Data Subcommittee on April 13, 2004, and 
February 11, 2005. The Observation Subcommittee, which was established 
on June 24, 2003, and reestablished with new members on March 8, 2004, 
and February 11, 2005, reviews and makes recommendations to the APC 
Panel on all issues pertaining to observation services paid under the 
OPPS, such as coding and operational issues. The Packaging 
Subcommittee, which was established on March 8, 2004 and reestablished 
with new members on February 11, 2005, studies and makes 
recommendations on issues pertaining to services that are not 
separately payable under the OPPS but are bundled or packaged APC 
payments. Each of these subcommittees was established by a majority 
vote of the APC Panel during a scheduled APC Panel meeting. All 
subcommittee recommendations are discussed and voted upon by the full 
APC Panel.
    For a detailed discussion of the APC Panel meetings, refer to the 
hospital OPPS final rules cited in section I.C. of this preamble. Full 
discussion of the recommendations resulting from the APC Panel's 
February 2005 meeting are included in the sections of this preamble 
that are specific to each recommendation.

E. Provisions of the Medicare Prescription Drug, Improvement, and 
Modernization Act of 2003 To Be Implemented Beginning in CY 2006

    On December 8, 2003, the Medicare Prescription Drug, Improvement, 
and Modernization Act of 2003 (MMA), Pub. L. 108-173, was enacted. Pub. 
L. 108-173 made changes to the Act relating to the Medicare OPPS. In 
the January 6, 2004 interim final rule with comment period and the 
November 15, 2004 final rule with comment period, we implemented 
provisions of Pub. L. 108-173 relating to the OPPS that were effective 
for CY 2004 and CY 2005, respectively. Provisions of Pub. L. 108-173 
that were implemented in CY 2004 or CY 2005, and that are continuing in 
CY 2006, are discussed throughout this proposed rule. Moreover, in this 
proposed rule, we are proposing to implement the following provisions 
of Pub. L. 108-173 that affect the OPPS beginning in CY 2006:
1. Hold Harmless Provisions
    Section 411 of Pub. L. 108-173 amended section 1833(t)(7)(D)(i) of 
the Act and extended the hold harmless provision for small rural 
hospitals having 100 or fewer beds through December 31, 2005. Section 
411 of Pub. L. 108-173 further amended section 1833(t)(7) of the Act to 
provide that hold-harmless transitional corridor payments shall apply 
through December

[[Page 42679]]

31, 2005 to sole community hospitals (SCHs) (as defined in section 
1886(d)(5)(D)(iii) of the Act) located in a rural area. In accordance 
with these provisions, effective January 1, 2006, we are proposing to 
discontinue transitional corridor payments for small rural hospitals 
having 100 or fewer beds and for SCHs located in a rural area.
2. Study and Authorization of Adjustment for Rural Hospitals
    Section 411(b) of Pub. L. 108-173 added a new paragraph (13) to 
section 1833(t) of the Act to authorize an ``Adjustment for Rural 
Hospitals''. This provision requires us to conduct a study to determine 
if costs incurred by hospitals located in rural areas by APCs exceed 
those costs incurred by hospitals located in urban areas. This 
provision further requires us to provide for an appropriate adjustment 
by January 1, 2006, if we find that the costs incurred by hospitals 
located in rural areas exceed those costs incurred by hospitals located 
in urban areas.
3. Payment for ``Specified Covered Outpatient Drugs''
    Section 621(a)(1) of Pub. L. 108-173 added section 1833(t)(14) to 
the Act that specifies payments for certain ``specified covered 
outpatient drugs'' beginning in 2006. Specifically, section 
1833(t)(14)(A)(iii)(I) of the Act states that such payment shall be 
equal to what we determine to be the average acquisition cost for the 
drug, taking into account hospital acquisition cost survey data 
furnished by the Government Accountability Office (GAO). Section 
1833(t)(14)(A)(iii)(II) of the Act further notes that if hospital 
acquisition cost data are not available, payment for specified covered 
outpatient drugs shall equal the average price for the drug established 
under section 1842(o), section 1847(A), or section 1847(B) of the Act 
as calculated and adjusted by the Secretary as necessary. Both payment 
approaches are subject to adjustments under section 1833(t)(14)(E) of 
the Act as discussed below.
4. Adjustment in Payment Rates for ``Specified Covered Outpatient 
Drugs'' for Overhead Costs
    Section 621(a)(1) of Pub. L. 108-173 added section 1833(t)(14)(E) 
to the Act. Section 1833(t)(14)(E)(ii) of the Act authorizes us to make 
an adjustment to payments for ``specified covered outpatient drugs'' to 
take into account overhead and related expenses such as pharmacy 
services and handling costs, based on recommendations contained in a 
report prepared by the Medicare Payment Advisory Commission (MedPAC).
5. Budget Neutrality Adjustment
    Section 621(a)(1) of Pub. L. 108-173 amended the Act by adding 
section 1833(t)(14)(H), which requires that additional expenditures 
resulting from adjustments in APC payment rates for specified covered 
outpatient drugs be taken into account beginning in CY 2006 and 
continuing in subsequent years, in establishing the OPPS conversion, 
weighting, and other adjustment factors.

F. CMS' Commitment to New Technologies

(If you choose to comment on issues in this section, please include 
the caption ``Commitment to New Technologies'' at the beginning of 
your comment.)

    CMS is committed to ensuring that Medicare beneficiaries will have 
timely access to new medical treatments and technologies that are well-
evaluated and demonstrated to be effective. We launched the Council on 
Technology and Innovation (CTI) to provide the Agency with improved 
methods for developing practical information about the clinical 
benefits of new medical technologies to result in faster and more 
efficient coverage and payment of these medical technologies. The CTI 
supports CMS efforts to develop better evidence on the safety, 
effectiveness, and cost of new and approved technologies to help 
promote their more effective use.
    We want to provide doctors and patients with better information 
about the benefits of new medical treatments and/or technologies, 
especially compared to other treatment options. We also want 
beneficiaries to have access to valuable new medical innovations as 
quickly and efficiently as possible. We note there are a number of 
payment mechanisms in the OPPS and the IPPS designed to achieve 
appropriate payment of promising new technologies. In the OPPS, 
qualifying new medical devices may be paid on a cost basis by means of 
transitional pass-through payments, in addition to the APC payments for 
the procedures which utilize the devices. In addition, qualifying new 
services may be assigned for payment to New Technology APCs or, if 
appropriate, to regular clinical APCs. In the IPPS, qualifying new 
technologies may receive add-on payments to the standard diagnosis-
related group (DRG) payments. We also note that collaborative efforts 
are underway to facilitate coordination between the Food and Drug 
Administration (FDA) and CMS with regard to streamlining the CMS 
coverage process by which new technologies come to the marketplace.
    To promote timely access to new medical treatments and 
technologies, in this proposed rule we are proposing enhancements to 
both the OPPS pass-through payment criteria for devices as discussed in 
section IV.D.2. of this preamble and the qualifying process for 
assignment of new services to New Technology APCs or regular clinical 
APCs discussed in section III.C.3. of this preamble. We are proposing 
to make device pass-through eligibility available to a broader range of 
qualifying devices. We are also proposing to change the application and 
review process for assignment of new services to New Technology APCs to 
promote thoughtful review of the coding, clinical use and efficacy of 
new services by the wider medical community, encouraging appropriate 
dissemination of new technologies. These enhancements are explained in 
this proposed rule.

G. Summary of the Major Content of This Proposed Rule

    In this proposed rule, we are setting forth proposed changes to the 
Medicare hospital OPPS for CY 2006. These changes would be effective 
for services furnished on or after January 1, 2006. The following is a

for services provided by nonphysician practitioners such as physician 
assistants, nurse practitioners, and clinical nurse specialists in 
critical access hospitals (CAHs).

II. Proposed Updates Affecting Payments for CY 2006

A. Recalibration of APC Relative Weights for CY 2006

(If you choose to comment on the issues in this section, please 
include the caption ``APC Relative Weights'' at the beginning of 
your comment.)
1. Database Construction
a. Database Source and Methodology
    Section 1833(t)(9)(A) of the Act requires that the Secretary review 
and revise the relative payment weights for APCs at least annually. In 
the April 7, 2000 OPPS final rule (65 FR 18482), we explained in detail 
how we calculated the relative payment weights that were implemented on 
August 1, 2000, for each APC group. Except for some reweighting due to 
a small number of APC changes, these relative payment weights continued 
to be in effect for CY 2001. This policy is discussed in the November 
13, 2000 interim final rule (65 FR 67824 through 67827).
    We are proposing to use the same basic methodology that we 
described in the April 7, 2000 final rule to recalibrate the APC 
relative payment weights for services furnished on or after January 1, 
2006, and before January 1, 2007. That is, we would recalibrate the 
relative payment weights for each APC based on claims and cost report 
data for outpatient services. We are proposing to use the most recent 
available data to construct the database for calculating APC group 
weights. For the purpose of recalibrating APC relative payment weights 
for CY 2006, we used approximately 127 million final action claims for 
hospital OPD services furnished on or after January 1, 2004, and before 
January 1, 2005. Of the 127 million final action claims for services 
provided in hospital outpatient settings, 102 million claims were of 
the type of bill potentially appropriate for use in setting rates for 
OPPS services (but did not necessarily contain services payable under 
the OPPS). Of the 102 million claims, we were able to use 49 million 
whole claims to set the proposed OPPS APC relative weights for CY 2006 
OPPS. From the 49 million whole claims, we created 81 million single 
records, of which 50 million were ``pseudo'' single claims (created 
from multiple procedure claims using the process we discuss in this 
section).
    The proposed APC relative weights and payments in Addenda A and B 
to this proposed rule were calculated using claims from this period 
that had been processed before January 1, 2005. We selected claims for 
services paid under the OPPS and matched these claims to the most 
recent cost report filed by the individual hospitals represented in our 
claims data. We are proposing that the APC relative payment weights for 
CY 2006 under the OPPS would continue to be based on the median 
hospital costs for services in the APC groups. For the CY 2006 OPPS 
final rule, we are proposing to base APC median costs on

[[Page 42681]]

claims for services furnished in CY 2004 and processed before June 30, 
2005.
b. Proposed Use of Single and Multiple Procedure Claims
    For CY 2006, we are proposing to continue to use single procedure 
claims to set the medians on which the APC relative payment weights 
would be based. As noted in the November 15, 2004 final rule with 
comment period, we have received many requests asking that we ensure 
that the data from claims that contain charges for multiple procedures 
are included in the data from which we calculate the relative payment 
weights (69 FR 65730 through 65731). Requesters believe that relying 
solely on single procedure claims to recalibrate APC relative payment 
weights fails to take into account data for many frequently performed 
procedures, particularly those commonly performed in combination with 
other procedures. They believe that, by depending upon single procedure 
claims, we base relative payment weights on the least-costly services, 
thereby introducing downward bias to the medians on which the weights 
are based.
    We agree that, optimally, it is desirable to use the data from as 
many claims as possible to recalibrate the APC relative payment 
weights, including those with multiple procedures. We generally use 
single procedure claims to set the median costs for APCs because we 
are, so far, unable to ensure that packaged costs can be appropriately 
allocated across multiple procedures performed on the same date of 
service. However, by bypassing specified codes that we believe do not 
have significant packaged costs, we are able to use more data from 
multiple procedure claims. In many cases this enables us to create 
multiple ``pseudo'' single claims from claims that, as submitted, 
contained multiple separately paid procedures on the same claim. We 
have used the date of service on the claims and a list of codes to be 
bypassed to create ``pseudo'' single claims from multiple procedure 
claims the same as we did in recalibrating the CY 2005 APC relative 
payment weights. We refer to these newly created single procedure 
claims as ``pseudo'' singles because they were submitted by providers 
as multiple procedure claims.
    For CY 2003, we created ``pseudo'' single claims by bypassing HCPCS 
codes 93005 (Electrocardiogram, tracing), 71010 (Chest x-ray), and 
71020 (Chest x-ray) on a submitted claim. However, we did not use 
claims data for the bypassed codes in the creation of the median costs 
for the APCs to which these three codes were assigned because the level 
of packaging that would have remained on the claim after we selected 
the bypass code was not apparent and, therefore, it was difficult to 
determine if the medians for these codes would be correct.
    For CY 2004, we created ``pseudo'' single claims by bypassing these 
three codes and also by bypassing an additional 269 HCPCS codes in 
APCs. We selected these codes based on a clinical review of the 
services and because it was presumed that these codes had only very 
limited packaging and could appropriately be bypassed for the purpose 
of creating ``pseudo'' single claims. The APCs to which these codes 
were assigned were varied and included mammography, cardiac 
rehabilitation, and Level I plain film x-rays. To derive more 
``pseudo'' single claims, we also split the claims where there were 
dates of service for revenue code charges on that claim that could be 
matched to a single procedure code on the claim on the same date.
    As in CY 2003, we did not include the claims data for the bypassed 
codes in the creation of the APCs to which the 269 codes were assigned 
because, again, we had not established that such an approach was 
appropriate and would aid in accurately estimating the median cost for 
that APC. For CY 2004, from about 16.3 million otherwise unusable 
claims, we used about 9.5 million multiple procedure claims to create 
about 27 million ``pseudo'' single claims. For CY 2005, we created 383 
bypass codes and from approximately 24 million otherwise unusable 
claims, we used about 18 million multiple procedure claims to create 
about 52 million ``pseudo'' single claims.
    For CY 2006, we are proposing to continue using date of service 
matching as a tool for creation of ``pseudo'' single claims and to 
continue the use of a bypass list to create ``pseudo'' single claims. 
The process we are proposing for CY 2006 OPPS results in our being able 
to use some part of 90 percent of the total claims that are eligible 
for use in OPPS ratesetting and modeling in developing this proposed 
rule. This process enabled us to use, for CY 2006, 81 million single 
bills for ratesetting: 50 million ``pseudo'' singles and 31 million 
``natural'' single bills (bills that were submitted containing only one 
separately payable major HCPCS code).
    We are proposing to bypass the 404 codes identified in Table 1 to 
create new single claims and to use the line-item costs associated with 
the bypass codes on these claims in the creation of the median costs 
for the APCs into which they are assigned. Of the codes on this list, 
345 were used for bypass in CY 2005. We are proposing to continue the 
use of the codes on the CY 2005 OPPS bypass list and expand it by 
adding 46 codes that, using data presented to the APC Panel at its 
February 2005 meeting, meet the same empirical criteria as those used 
in CY 2005 to create the bypass list. Our examination of the data 
against the criteria for inclusion on the bypass list, as discussed 
below for the addition of new codes, shows that the empirically 
selected codes used for bypass for the CY 2005 OPPS generally continue 
to meet the criteria or come very close to meeting the criteria, and we 
have received no comments against bypassing them.
    To facilitate comment, Table 1 indicates the list of codes we are 
proposing to bypass for creation of ``pseudo'' singles for CY 2006 OPPS 
and indicates those used in the CY 2005 OPPS for bypass and those 
proposed to be added for the CY 2006 OPPS. Bypass codes shown in Table 
1 with an asterisk indicate the HCPCs codes we are proposing to add to 
the list for the CY 2006 OPPS. The criteria we are proposing to use to 
determine the additional codes to add to the CY 2005 OPPS bypass list 
in order to create the bypass list for CY 2006 OPPS are discussed 
below.
    The following empirical criteria were developed by reviewing the 
frequency and magnitude of packaging in the single claims for payable 
codes other than drugs and biologicals. We assumed that the 
representation of packaging on the single claims for any given code is 
comparable to packaging for that code in the multiple claims:
     There were 100 or more single claims for the code. This 
number of single claims ensured that observed outcomes were 
sufficiently representative of packaging that might occur in the 
multiple claims.
     Five percent or fewer of the single claims for the code 
had packaged costs on that single claim for the code. This criterion 
results in limiting the amount of packaging being redistributed to the 
payable procedure remaining on the claim after the bypass code is 
removed and ensures that the costs associated with the bypass code 
represent the cost of the bypassed service.
     The median cost of packaging observed in the single claim 
was equal to or less than $50. This limits the amount of error in 
redistributed costs.
     The code is not a code for an unlisted service.
    We also added to the bypass list three codes (CPT codes 51701, 
51702, and 51703 for bladder catheterization) which do not meet these 
criteria. These

[[Page 42682]]

codes have been packaged and have never been paid separately. For that 
reason, when these were the only services provided to the beneficiary, 
no payment was made to the hospital. The APC Panel's packaging 
subcommittee recommends that we make separate payment when they are the 
only service on the claim. See section II.A.4. of this preamble for 
further discussion of our proposal to pay them separately. We are 
proposing to add them to the bypass list because changing them from 
packaged to separately paid would result in the reduction of the number 
of single bills on which we could base median costs for other major 
separately paid procedures which are billed on the same claim with 
these procedure codes. Single bills which contain other procedures 
would become multiple procedure claims when these bladder 
catheterization codes were converted from packaged to separately paid 
status.
    We examined the packaging on the single procedure claims in the CY 
2004 data used for this proposed rule for these codes. We found that 
none of these codes met the empirical standards for the bypass list. 
However, we believe that when these services are performed on the same 
date as another separately paid procedure, any packaging that appears 
on the claim would appropriately be associated with the other 
procedures and not with these codes. Therefore, we believe that 
bypassing them does not adversely affect the medians for other 
procedures. Moreover, future separate payment for these codes does not 
harm the hospitals that furnish these services, in view of the 
historical absence of separate payment for them under the OPPS in the 
past. Hence, we propose to pay separately for these codes and to add 
them to the bypass list for the CY 2006 OPPS.
    We specifically invite public comment on the ``pseudo'' single 
process, including the bypass list and the criteria.

\1\ HCPCS codes shown with an asterisk are bypass codes we are proposing
  to add to the list for CY 2006.

2. Proposed Calculation of Median Costs for CY 2006
    In this section of the preamble, we discuss the use of claims to 
calculate the proposed OPPS payment rates for CY 2006. The hospital 
outpatient prospective payment page on the CMS Web site on which this 
proposed rule is posted provides an accounting of claims used in the 
development of the proposed rates: http://www.cms.hhs.gov/providers/hopps.
 The accounting of claims used in the development of the proposed 

rule is included on the Web site under supplemental materials for the 
CY 2006 proposed rule. That accounting provides additional detail 
regarding the number of claims derived at each stage of the process. In 
addition, below we discuss the files of claims that comprise the data 
sets that are available for purchase under a CMS data user contract. 
Our CMS Web site, http://www.cms.hhs.gov/providers/hopps, includes 

information about purchasing the following two OPPS data files: ``OPPS 
Limited Data Set'' and ``OPPS Identifiable Data Set.''
    We are proposing to use the following methodology to establish the 
relative weights to be used in calculating the proposed OPPS payment 
rates for CY 2006 shown in Addenda A and B to this proposed rule. This 
methodology is as follows:
    We used outpatient claims for full CY 2004 to set the proposed 
relative weights for CY 2006. To begin the calculation of the relative 
weights for CY 2006, we pulled all claims for outpatient services 
furnished in CY 2004 from the national claims history file. This is not 
the population of claims paid under the OPPS, but all outpatient claims 
(including, for example, CAH claims, and hospital claims for clinical 
laboratory services for persons who are neither inpatients nor 
outpatients of the hospital).
    We then excluded claims with condition codes 04, 20, 21, and 77. 
These are claims that providers submitted to Medicare knowing that no 
payment will be made. For example, providers submit claims with a 
condition code 21 to elicit an official denial notice from Medicare and 
document that a service is not covered. We then excluded claims for 
services furnished in Maryland, Guam, and the U.S. Virgin Islands 
because hospitals in those geographic areas are not paid under the 
OPPS.
    We divided the remaining claims into the three groups shown below. 
Groups 2 and 3 comprise the 102 million claims that contain hospital 
bill types paid under the OPPS.
    1. Claims that were not bill types 12X, 13X, 14X (hospital bill 
types), or 76X (CMHC bill types). Other bill types, such as ambulatory 
surgical centers (ASCs), bill type 83, are not paid under the OPPS and, 
therefore, these claims were not used to set OPPS payment.
    2. Claims that were bill types 12X, 13X, or 14X (hospital bill 
types). These claims are hospital outpatient claims.
    3. Claims that were bill type 76X (CMHC). (These claims are later 
combined with any claims in item 2 above with a condition code 41 to 
set the per diem partial hospitalization rate determined through a 
separate process.)
    For the cost-to-charge ratio (CCR) calculation process, we used the 
same approach as that used in developing the final APC rates for CY 
2005 (69 FR 65744). That is, we first limited the population of cost 
reports to only those for hospitals that filed outpatient claims in CY 
2004 before determining whether the CCRs for such hospitals were valid. 
This initial limitation changed the distribution of CCRs used during 
the trimming process discussed below.
    We then calculated the CCRs at a departmental level and overall for 
each hospital for which we had claims data. We did this using hospital-
specific data from the Hospital Cost Report Information System (HCRIS). 
We used the most recent available cost report data, in most cases, cost 
reports for CY 2002 or CY 2003. We used the most recent cost report 
available whether submitted or settled. If the most recent available 
cost report was submitted but not settled, we looked at the last 
settled cost report to determine the ratio of submitted to settled 
cost, and we then adjusted the most recent available submitted but not 
settled cost report using that ratio. We propose to use the most 
recently submitted cost reports to calculate the CCRs to be used to 
calculate median costs for the OPPS CY 2006 final rule.
    We then flagged CAHs, which are not paid under the OPPS, and 
hospitals with invalid CCRs. These included claims from hospitals 
without a CCR; those from hospitals paid an all-inclusive rate; those 
from hospitals with obviously erroneous CCRs (greater than 90 or less 
than .0001); and those from hospitals with CCRs that were identified as 
outliers (3 standard deviations from the geometric mean after removing 
error CCRs). In addition, we trimmed the CCRs at the departmental level 
by removing the CCRs for each cost center as outliers if they exceeded 
+/-3 standard deviations of the geometric mean. This is the same 
methodology that we used in developing the final CY 2005 CCRs. For CY 
2006, we are proposing to trim at the departmental CCR level to 
eliminate aberrant CCRs that, if found in high volume hospitals, could 
skew the medians. We used a four-tiered hierarchy of cost center CCRs 
to match a cost center to a revenue code with the top tier being the 
most common cost center and the last tier being the default CCR. If a 
hospital's departmental CCR was deleted by trimming, we set the 
departmental CCR for that cost center to ``missing,'' so that another 
departmental CCR in the revenue center hierarchy could apply. If no 
other departmental CCR could apply to the revenue code on the claim, we 
used the hospital's overall CCR for the revenue code in question. The 
hierarchy of CCRs is available for inspection and comment at the CMS 
Web site: http://www.cms.hhs.gov/providers/hopps/default.asp.

    We then converted the charges on the claim by applying the CCR that 
we believed was best suited to the revenue

[[Page 42689]]

code indicated on the line with the charge. Table 2 below in this 
preamble contains a list of the allowed revenue codes. Revenue codes 
not included in Table 2 are those not allowed under the OPPS because 
their services cannot be paid under the OPPS (for example, inpatient 
room and board charges) and, thus charges with those revenue codes were 
not packaged for creation of the OPPS median costs. If a hospital did 
not have a CCR that was appropriate to the revenue code reported for a 
line-item charge (for example, a visit reported under the clinic 
revenue code, but the hospital did not have a clinic cost center), we 
applied the hospital-specific overall CCR, except as discussed in 
section X. of this preamble, for calculation of costs for blood.
    Thus, we applied CCRs as described above to claims with bill types 
12X, 13X, or 14X, excluding all claims from CAHs and hospitals in 
Maryland, Guam, and the U.S. Virgin Islands, and flagged hospitals with 
invalid CCRs. We excluded claims from all hospitals for which CCRs were 
flagged as invalid.
    We identified claims with condition code 41 as partial 
hospitalization services of CMHCs and moved them to another file. These 
claims were combined with the 76X claims identified previously to 
calculate the proposed partial hospitalization per diem rate.
    We then excluded claims without a HCPCS code. We also moved claims 
for observation services to another file. We moved to another file 
claims that contained nothing but flu and pneumococcal pneumonia 
(``PPV'') vaccine. Influenza and PPV vaccines are paid at reasonable 
cost and, therefore, these claims are not used to set OPPS rates. We 
note that the two above mentioned separate files containing partial 
hospitalization claims and the observation services claims are included 
in the files that are available for purchase as discussed above.
    We next copied line-item costs for drugs, blood, and devices (the 
lines stay on the claim, but are copied off onto another file) to a 
separate file. No claims were deleted when we copied these lines onto 
another file. These line-items are used to calculate the per unit 
median for drugs, radiopharmaceuticals, and blood and blood products. 
The line-item costs were also used to calculate the per administration 
cost of drugs, radiopharmaceuticals, and biologicals (other than blood 
and blood products).
    We then divided the remaining claims into five groups.
    1. Single Major Claims: Claims with a single separately payable 
procedure, all of which would be used in median setting.
    2. Multiple Major Claims: Claims with more than one separately 
payable procedure or multiple units for one payable procedure. As 
discussed below, some of these can be used in median setting.
    3. Single Minor Claims: Claims with a single HCPCS code that is not 
separately payable. These claims may have a single packaged procedure 
or a drug code.
    4. Multiple Minor Claims: Claims with multiple HCPCS codes that are 
not separately payable without examining dates of service. For example, 
pathology codes are not used unless the pathology service is the single 
code on the bill or unless the pathology code is on a separate date of 
service from the other procedure on the claim. The multiple minor file 
has claims with multiple occurrences of pathology codes, with packaged 
costs that cannot be appropriately allocated across the multiple 
pathology codes. However, by matching dates of service for the code and 
the reported costs through the ``pseudo'' single creation process 
discussed earlier, a claim with multiple pathology codes may become 
several ``pseudo'' single claims with a unique pathology code and its 
associated costs on each day. These ``pseudo'' singles for the 
pathology codes would then be considered a separately payable code and 
would be used the same as claims in the single major claim file.
    5. Non-OPPS Claims: Claims that contain no services payable under 
the OPPS. These claims are excluded from the files used for the OPPS. 
Non-OPPS claims have codes paid under other fee schedules, for example, 
durable medical equipment or clinical laboratory.
    We note that the claims listed in numbers 1, 2, and 4 above are 
included in the data files that can be purchased as described above.
    We set aside the single minor claims and the non-OPPS claims 
(numbers 3 and 5 above) because we did not use either in calculating 
median cost. We then examined the multiple major and multiple minor 
claims (numbers 2 and 4 above) to determine if we could convert any of 
them to single major claims using the process described previously. We 
first grouped items on the claims by date of service. If each major 
procedure on the claim had a different date of service and if the line-
items for packaged HCPCS and packaged revenue codes had dates of 
service, we split the claim into multiple ``pseudo'' single claims 
based on the date of service.
    After those single claims were created, we used the list of 
``bypass codes'' in Table 1 of this preamble to remove separately 
payable procedures that we determined contain limited costs or no 
packaged costs from a multiple procedure bill. A discussion of the 
creation of the list of bypass codes used for the creation of 
``pseudo'' single claims is contained in section II.A.1.b. of this 
preamble.
    When one of the two separately payable procedures on a multiple 
procedure claim was on the bypass code list, we split the claim into 
two single procedure claims records. The single procedure claim record 
that contained the bypass code did not retain packaged services. The 
single procedure claim record that contained the other separately 
payable procedure (but no bypass code) retained the packaged revenue 
code charges and the packaged HCPCS charges. This enables us to use a 
claim that would otherwise be a multiple procedure claim and could not 
be used.
    We excluded those claims that we were not able to convert to 
singles even after applying both of the techniques for creation of 
``pseudo'' singles. We then packaged the costs of packaged HCPCS codes 
(codes with status indicator ``N'' listed in Addendum B to this 
proposed rule) and packaged revenue codes into the cost of the single 
major procedure remaining on the claim. The list of packaged revenue 
codes is shown in Table 2 below.
    After removing claims for hospitals with error CCRs, claims without 
HCPCS codes, claims for immunizations not covered under the OPPS, and 
claims for services not paid under the OPPS, 55 million claims were 
left. Of these 55 million claims, we were able to use some portion of 
49 million whole claims (90 percent of the potentially usable claims) 
to create the 81 million single and ``pseudo'' single claims for use in 
the CY 2006 median payment ratesetting.
    We also excluded (1) claims that had zero costs after summing all 
costs on the claim; (2) claims for which CMS lacked an appropriate 
provider wage index; and (3) claims containing token charges (charges 
of less than $1.01) or for which intermediary systems had allocated 
charges as if the charges were submitted on the claim. We are proposing 
to delete claims containing token charges. We do not believe that a 
charge of less than $1.01 would yield a cost that would be valid to set 
weights for a significant separately paid service. Moreover, effective 
for services furnished on or after July 1, 2004, the OCE assigns 
payment flag number 3 to claims on which hospitals submitted token 
charges for a service with status

[[Page 42690]]

indicator ``S'' or ``T'' (a major separately paid service under OPPS) 
for which the intermediary is required to allocate the sum of charges 
for services with a status indicator equaling ``S'' or ``T'' based on 
the weight for the APC to which each code is assigned. We do not 
believe that these charges, which were token charges as submitted by 
the hospital, are valid reflections of hospital resource and that they 
should not be used to set median costs. Therefore, we are proposing to 
delete these claims.
    For the remaining claims, we then wage adjusted 60 percent of the 
cost of the claim (which we have previously determined to be the labor-
related portion), as has been our policy since the initial 
implementation of the OPPS, to adjust for geographic variation in 
labor-related costs. We made this adjustment by determining the wage 
index that applied to the hospital that furnished the service and 
dividing the cost for the separately paid HCPCS code furnished by the 
hospital by that wage index. As has been our policy since the inception 
of the OPPS, we are proposing to use the pre-reclassified wage indices 
for standardization because we believe that they better reflect the 
true costs of items and services in the area in which the hospital is 
located than the post-reclassification wage indices, and would result 
in the most accurate adjusted median costs.
    We then excluded claims that were outside 3 standard deviations 
from the geometric mean cost for each HCPCS code. We used the remaining 
claims to calculate median costs for each separately payable HCPCS 
code; first, to determine the applicability of the ``2 times'' rule, 
and second, to determine APC medians based on the claims containing the 
HCPCS codes assigned to each APC. As stated previously, section 
1833(t)(2) of the Act provides that, subject to certain exceptions, the 
items and services within an APC group cannot be considered comparable 
with respect to the use of resources if the highest median (or mean 
cost, if elected by the Secretary) for an item or service in the group 
is more than 2 times greater than the lowest median cost for an item or 
service within the same group (``the 2 times rule''). Finally, we 
reviewed the medians and reassigned HCPCS codes to different APCs as 
deemed appropriate. Section III.B. of this preamble includes a 
discussion of the HCPCS code assignment changes that resulted from 
examination of the medians and for other reasons. The APC medians were 
recalculated after we reassigned the affected HCPCS codes.
    A detailed discussion of the medians for blood and blood products 
is included in section X. of this preamble. A discussion of the medians 
for APCs that require one or more devices when the service is performed 
is included in section IV.A. of this preamble. A discussion of the 
median for observation services is included in section XI. of this 
preamble and a discussion of the median for partial hospitalization is 
included below in section II.B. of this preamble.

3. Proposed Calculation of Scaled OPPS Payment Weights
    Using the median APC costs discussed previously, we calculated the 
proposed relative payment weights for each APC for CY 2006 shown in 
Addenda A and B to this proposed rule. As in prior years, we scaled all 
the relative payment weights to APC 0601 (Mid Level Clinic Visit) 
because it is one of the most frequently performed services in the 
hospital outpatient setting. We assigned APC 0601 a relative payment 
weight of 1.00 and divided the median cost for each APC by the median 
cost for APC 0601 to derive the relative payment weight for each APC. 
Using CY 2004 data, the median cost for APC 0601 is $60.57 for CY 2006.
    Section 1833(t)(9)(B) of the Act requires that APC reclassification 
and recalibration changes, wage index changes, and other adjustments be 
made in a manner that assures that aggregate payments under the OPPS 
for CY 2006 are neither greater than nor less than the aggregate 
payments that would have been made without the changes. To comply with 
this requirement concerning the APC changes, we compared aggregate 
payments using the CY 2005 relative weights to aggregate payments using 
the CY 2006 proposed relative weights. Based on this comparison, we are 
proposing to make an adjustment to the relative weights for purposes of 
budget neutrality. The unscaled relative payment weights were adjusted 
by .999207669 for budget neutrality. The proposed relative payment 
weights are listed in Addenda A and B to this proposed rule. The 
proposed relative payment weights incorporate the recalibration 
adjustments discussed in sections II.A.1. and 2.

[[Page 42691]]

    Section 1833(t)(14)(H) of the Act, as added by section 621(a)(1) of 
Pub. L. 108-173, states that ``Additional expenditures resulting from 
this paragraph shall not be taken into account in establishing the 
conversion factor, weighting and other adjustment factors for 2004 and 
2005 under paragraph (9) but shall be taken into account for subsequent 
years.'' Section 1833(t)(14) of the Act provides the payment rates for 
certain ``specified covered outpatient drugs.'' Therefore, the 
incremental cost of those specified covered outpatient drugs (as 
discussed in section V. of this preamble) is included in the budget 
neutrality calculations.
    Under section 1833(t)(16)(C) of the Act, as added by section 
621(b)(1) of Pub. L. 108-173, payment for devices of brachytherapy 
consisting of a seed or seeds (or radioactive source) is to be made at 
charges adjusted to cost for services furnished on or after January 1, 
2004, and before January 1, 2006. As we stated in our January 6, 2004 
interim final rule, charges for the brachytherapy sources will not be 
used in determining outlier payments and payments for these items will 
be excluded from budget neutrality calculations. (We provide a 
discussion of brachytherapy payment issues at section VII. of this 
proposed rule.)
4. Proposed Changes to Packaged Services
    Payments for packaged services under the OPPS are bundled into the 
payments providers receive for separately payable services provided on 
the same day. Packaged services are identified by the status indicator 
``N.'' Hospitals include charges for packaged services on their claims, 
and the costs associated with these packaged services are then bundled 
into the costs for separately payable procedures on the claims for 
purposes of median cost calculations. Hospitals may use CPT codes to 
report any packaged services that were performed, consistent with CPT 
coding guidelines.
    As a result of requests from the public, a Packaging Subcommittee 
to the APC Panel was established to review all the procedural CPT codes 
with a status indicator of ``N.''
    Providers have often suggested that many packaged services could be 
provided alone, without any other separately payable services on the 
claim, and requested that these codes not be assigned status indicator 
``N.'' The Packaging Subcommittee reviewed every code that was packaged 
in the CY 2004 OPPS. Based on comments we have received and their own 
expert judgment, the subcommittee identified a set of packaged codes 
that are often provided separately and subsequently reviewed 
utilization and median cost data for these codes. One of the main 
criteria utilized by the Packaging Subcommittee to determine whether a 
code should become unpackaged was how likely it was for the code to be 
billed without any other separately payable services on the claim. The 
Packaging Subcommittee also examined median costs from hospital claims 
for packaged services that were billed alone.
    The Packaging Subcommittee identified areas for change for some 
packaged CPT codes that they believe could frequently be provided to 
patients as the sole service on a given date and that require 
significant hospital resources as determined from hospital claims data. 
During the February 2005 meeting, the APC Panel accepted the report of 
the Packaging Subcommittee and made the following recommendations:
    (1) That packaged codes be reviewed by the Panel individually.
    (2) That the Packaging Subcommittee continue to meet throughout the 
year to discuss problematic packaged codes.
    (3) That CMS assign a modifier to CPT codes 36540 (Collect blood, 
venous device); 36600 (Withdrawal of arterial blood); and 51701 
(Insertion of non-indwelling bladder catheter), for use when there are 
no other separately payable codes on the claim. The modifier would flag 
the outpatient code editor (OCE) to assign payment to the claim.
    (4) That CMS maintain the current packaged status indicator for CPT 
code 76937 (Ultrasound guidance for vascular access).
    (5) That CMS change the status indicators for CPT immunization 
administration codes 90471 and 90472 to allow separate payment and 
ensure consistency with other injection codes.
    (6) That CMS gather more data on CPT code 94762 (Overnight pulse 
oximetry) to determine how often this code is billed without any other 
separately payable codes and whether it is performed more frequently 
alone in rural settings than other settings.
    (7) No changes to the packaged status of CPT codes 77790 (radiation 
source handling) and 94760 and 94761 (both codes measure blood oxygen 
levels).
    (8) That CMS provide education and consistent guidelines to 
providers and fiscal intermediaries on correct billing procedures for 
packaged codes in general and in particular for CPT codes 36540, 36600, 
and 51701 and the recommended modifier, if approved.
    (9) That the Packaging Subcommittee review CPT codes 42550 
(Injection for salivary x-ray) and 38792 (Sentinel node imaging).
    (10) That CPT code 97602 (Nonselective wound care) be referred to 
the Physician Payment Group within CMS for evaluation of its bundled 
status as it relates to services provided under the OPPS and that the 
Physician Payment Group report its conclusions back to the APC Panel.
    For CY 2006, we are proposing to maintain CPT codes 36540 (Collect 
blood venous device) and 36600 (Withdrawal of arterial blood) as 
packaged services and not adopt the APC Panel's recommendation to add a 
modifier. We note CPT code 36540 is also bundled under the Medicare 
Physician Fee Schedule (MPFS), and our data demonstrate that the 
service is generally billed with other separately payable services. We 
also have relatively few single claims for CPT code 36600, compared to 
the procedure's overall frequency. Both of these codes have relatively 
low resource utilization. As these procedures are almost always 
provided with other separately payable services, hospitals' payments 
for those other services include the costs of CPT codes 36540 and 
36600.
    For CY 2006, we are proposing to pay separately for CPT code 51701 
(Insertion of non-indwelling bladder catheter), and to map it to APC 
0340 (Minor Ancillary Procedures), with status indicator ``X'', and a 
median cost of $38.52. The APC Panel recommended that we pay separately 
for this code only when there are no other separately payable services 
on the claim. However, we are proposing to pay separately for this code 
every time it is billed. We believe that it is more appropriate to make 
payment for each procedure rather than increase hospitals' 
administrative burden by requiring specific coding changes to indicate 
that there are no other separately payable procedures on the claim. 
Based on our review of the data, the cost for this procedure is not 
insignificant, and the volume of single and multiple claims is modest. 
When we reviewed related codes, including CPT code 51702 (Insertion of 
temporary indwelling bladder catheter, simple) and CPT code 51703 
(Insertion of temporary indwelling bladder catheter, complicate), we 
noted that these codes also had substantial median costs and a moderate 
volume of single claims. Therefore, for CY 2006, we are also proposing 
to pay separately for CPT codes 51702 and 51703, mapping them to APC 
0340 with a median cost of $38.52 and APC 0164 (Level I Urinary

[[Page 42692]]

and Anal Procedures) with a median cost of $71.54, respectively. CPT 
codes 51701, 51702, and 51703 will be placed on the bypass list, as 
discussed in section II.A.1.b. of this proposed rule.
    For CY 2006, we are proposing to accept the APC Panel 
recommendation that CPT code 76937 (Ultrasound guidance for vascular 
access) remain packaged. We are concerned that there may be unnecessary 
overuse of this procedure if it is separately payable. In addition, we 
believe that the service would always be provided with another 
separately payable procedure, so its costs would be appropriately 
bundled with the definitive vascular access service. As stated in the 
CY 2005 final rule with comment period (69 FR 65697), CMS and the 
Packaging Subcommittee reviewed CY 2004 claims data for CPT code 76937 
and determined that this code should remain packaged.
    For CY 2006, see section VIII. of this preamble on drug 
administration regarding CPT codes 90471 and 90472.
    For CY 2006, we are proposing to accept the APC Panel 
recommendations that CPT codes 77790 (Radiation handling), 94760 (Pulse 
oximetry for oxygen saturation, single determination), and 94761 (Pulse 
oximetry for oxygen saturation, multiple determinations) remain 
packaged. We believe that CPT code 77790 is integral to the provision 
of brachytherapy and should always be billed on the same day with 
brachytherapy sources and their loading, ensuring that the provider 
would receive appropriate payment for the radiation source handling and 
loading bundled with the payment for the brachytherapy service. The 
small number of single claims for this code in our data verifies that 
this code is rarely billed alone without other payable services on the 
claim, and those few single claims may be miscoded claims. Our data 
review of CPT codes 94760 and 94761 revealed that these codes have low 
resource utilization, and are most frequently provided with other 
services. Similar to CPT code 77790, there are many fewer single claims 
for CPT codes 94760 and 94761 than multiple procedure claims that 
include CPT codes 94760 and 94761. CPT codes 94760 and 94761 describe 
services that are very commonly performed in the hospital outpatient 
setting, and unpackaging these codes would likely significantly 
decrease the number of single claims available for use in calculating 
median costs for other services.
    For CY 2006, we are proposing to accept the APC Panel 
recommendation to gather data and review CPT codes 94762, 42550, and 
38792 with the Packaging Subcommittee. We will analyze single and 
multiple procedure claims' volumes and resource utilization data, and 
review these studies with the Packaging Subcommittee.
    We referred CPT code 97602 (non-selective wound care) for MPFS 
evaluation of its bundled status as CPT code 97602 relates to services 
provided under the OPPS. CPT code 97602 is assigned status indicator 
``A'' in this OPPS proposed rule, meaning that while it is no longer 
payable under the OPPS, it is payable under a fee schedule other than 
OPPS. Under the MPFS, the nonselective wound care services described by 
CPT code 97602 are ``bundled'' into the selective wound care 
debridement codes (CPT codes 97597 and 97598). Under the MPFS, a 
separate payment is never made for ``bundled'' services and, because of 
this designation, the provider does not receive separate payment for 
non-selective wound care described by CPT code 97602. While this code 
now falls under the MPFS rules, payment policy for this ``bundled'' 
service has not changed and separate payment is not made.
    The APC Panel Packaging Subcommittee remains active, and additional 
issues and new data concerning the packaging status of codes will be 
shared for its consideration as information becomes available. We 
continue to encourage submission of common clinical scenarios involving 
currently packaged HCPCS codes to the Packaging Subcommittee for its 
ongoing review. Additional detailed suggestions for the Packaging 
Subcommittee should be submitted to APCPanel@cms.hhs.gov, with 
``Packaging Subcommittee'' in the subject line.

B. Proposed Payment for Partial Hospitalization

(If you choose to comment on issues in this section, please include 
the caption ``Partial Hospitalization'' at the beginning of your 
comment.)
1. Background
    Partial hospitalization is an intensive outpatient program of 
psychiatric services provided to patients as an alternative to 
inpatient psychiatric care for beneficiaries who have an acute mental 
illness. A partial hospitalization program (PHP) may be provided by a 
hospital to its outpatients or by a Medicare-certified CMHC. Section 
1833(t)(1)(B)(i) of the Act provides the Secretary with the authority 
to designate the hospital outpatient services to be covered under the 
OPPS. Section 419.21(c) of the Medicare regulations that implement this 
provision specifies that payments under the OPPS will be made for 
partial hospitalization services furnished by CMHCs. Section 
1883(t)(2)(C) of the Act requires that we establish relative payment 
weights based on median (or mean, at the election of the Secretary) 
hospital costs determined by 1996 claims data and data from the most 
recent available cost reports. Payment to providers under the OPPS for 
PHPs represents the provider's overhead costs associated with the 
program. Because a day of care is the unit that defines the structure 
and scheduling of partial hospitalization services, we established a 
per diem payment methodology for the PHP APC, effective for services 
furnished on or after August 1, 2000. For a detailed discussion, refer 
to the April 7, 2000 OPPS final rule (65 FR 18452).
2. Proposed PHP APC Update for CY 2006
    To calculate the proposed CY 2006 PHP per diem payment, we used the 
same methodology that was used to compute the CY 2005 PHP per diem 
payment. For CY 2005, the per diem amount was based on 12 months of 
hospital and CMHC PHP claims data (for services furnished from January 
1, 2003 through December 31, 2003). We used data from all hospital 
bills reporting condition code 41, which identifies the claim as 
partial hospitalization, and all bills from CMHCs because CMHCs are 
Medicare providers only for the purpose of providing partial 
hospitalization services. We used CCRs from the most recently available 
hospital and CMHC cost reports to convert each provider's line-item 
charges as reported on bills, to estimate the provider's cost for a day 
of PHP services. Per diem costs were then computed by summing the line-
item costs on each bill and dividing by the number of days on the bill.
    In a Program Memorandum issued on January 17, 2003 (Transmittal A-
03-004), we directed fiscal intermediaries to recalculate hospital and 
CMHC CCRs using the most recently settled cost reports by April 30, 
2003. Following the initial update of CCRs, fiscal intermediaries were 
further instructed to continue to update a provider's CCR and enter 
revised CCRs into the outpatient provider specific file. Therefore, for 
CMHCs, we use CCRs from the outpatient provider specific file.
    Historically, the median per diem cost for CMHCs has greatly 
exceeded the median per diem cost for hospital-based PHPs and has 
fluctuated significantly

[[Page 42693]]

from year to year while the median per diem cost for hospital-based 
PHPs has remained relatively constant ($200-$225). Medicare providers 
are required to maintain uniform charges for all payers. We believe 
that hospitals have multiple payers and are far less likely to 
significantly change their charges for PHP from year to year. However, 
many CMHCs have indicated that Medicare is their only payer. As a 
result, we believe that these providers may have increased and 
decreased their charges in response to Medicare payment policies. As 
discussed in more detail in the next section and in the final rule 
establishing the CY 2004 OPPS (68 FR 63470), we believe that some CMHCs 
manipulated their charges in order to inappropriately receive outlier 
payments.
    In the CY 2003 update, the difference in median per diem cost for 
CMHCs and hospital-based PHPs was so great, $685 for CMHCs and $225 for 
hospital-based PHPs, that we applied an adjustment factor of .583 to 
CMHC costs to account for the difference between ``as submitted'' and 
``final settled'' cost reports. By doing so, the CMHC median per diem 
cost was reduced to $384, resulting in a combined hospital-based and 
CMHC PHP median per diem cost of $273. As with all APCs in the OPPS, 
the median cost for each APC was scaled to be relative to the cost of a 
mid-level office visit and the conversion factor was applied. The 
resulting per diem rate for PHP for CY 2003 was $240.03.
    In the CY 2004 OPPS update, the median per diem cost for CMHCs grew 
to $1038, while the median per diem cost for hospital-based PHPs was 
again $225. After applying the .583 adjustment factor to the median 
CMHC per diem cost, the median CMHC per diem cost was $605. As the CMHC 
median per diem cost exceeded the average per diem cost of inpatient 
psychiatric care, we proposed a per diem rate for CY 2004 based solely 
on hospital-based PHP data. The proposed PHP per diem for CY 2004, 
after scaling, was $208.95. However, by the time we published the OPPS 
final rule for CY 2004, we had received updated CCRs for CMHCs. Using 
the updated CCRs significantly lowered the CMHC median per diem cost to 
$440. As a result, we determined that the higher per diem cost for 
CMHCs was not due to the difference between ``as submitted'' and 
``final settled'' cost reports, but were the result of excessive 
increases in charges which may have been done in order to receive 
higher outlier payments. Therefore, in calculating the PHP median per 
diem cost for CY 2004, we did not apply the .583 adjustment factor to 
CMHC costs to compute the PHP APC. Using the updated CCRs for CMHCs, 
the combined hospital-based and CMHC median per diem cost for PHP was 
$303. After scaling, we established the CY 2004 PHP APC of $286.82.
    Then, in the CY 2005 OPPS update, the CMHC median per diem cost was 
$310 and the hospital-based PHP median per diem cost was $215. No 
adjustments were determined to be necessary and, after scaling, the 
combined median per diem cost of $289 was reduced to $281.33. We 
believed that the reduction in the CMHC median per diem cost indicated 
that the use of updated CCRs had accounted for the previous increase in 
CMHC charges, and represented a more accurate estimate of CMHC per diem 
costs for PHP.
    For CY 2006, we analyzed 12 months of data for hospital and CMHC 
PHP claims for services furnished between January 1, 2004, and December 
31, 2004. The data indicated that the median per diem cost for CMHCs 
had dropped to $143, while the median per diem cost for hospital-based 
PHPs was $209. It appears that CMHCs significantly reduced their 
charges in CY 2004. The average charge per day for CMHCs in CY 2003 was 
$1,184 and the average cost per day was $335. In CY 2004, the CMHC 
average charge per day dropped to $765 and the average cost per day was 
$167. We have determined that a combination of lower charges and 
slightly lower CCRs for CMHCs resulted in a significant decline in the 
CMHC median per diem cost.
    Following the methodology used for the CY 2005 OPPS update, the 
combined hospital-based and CMHC median per diem cost would be $149, a 
decrease of 48 percent compared to the CY 2005 combined median per diem 
amount. We believe that after scaling this amount to the cost of a mid-
level office visit, the resulting APC rate would be too low to cover 
the per diem cost for all PHPs.
    We are considering an alternative update methodology for the PHP 
APC for CY 2006 that would mitigate this drastic reduction in payment 
for PHP. One alternative would be to base the PHP APC on hospital-based 
PHP data alone. The median per diem cost of hospital-based PHPs has 
remained in the $200-225 range over the last 5 years, while the median 
per diem cost for CMHC PHPs has fluctuated significantly from a high of 
$1,037 to a low of $143. Under this alternative, we would use $209, the 
median per diem cost for hospital-based PHPs during CY 2004 to 
establish the PHP APC for CY 2006. However, we believe using this 
amount would also result in an unacceptable drop in Medicare payments 
for all PHPs in CY 2006 compared to payments in CY 2005.
    Another alternative we are considering is to apply a different 
trimming methodology to CMHC costs in an effort to eliminate the effect 
of data for those CMHCs that appeared to have excessively increased 
their charges in order to receive outlier payments. We compared CMHC 
per diem costs in CY 2003 to CMHC per diem costs in CY 2004 and 
determined the percentage change. Initially, we trimmed CMHCs claims 
where the CMHC's per diem costs changed by 50 percent or more from CY 
2003 to CY 2004. After combining the remaining CMHC claims with the 
hospital-based PHP claims, we calculated a median per diem cost of 
$160.75. However, this approach did not eliminate the data for all of 
the CMHCs with unreasonable per diem costs. We then analyzed the 
resulting median per diem cost if we trimmed CMHC claims where the 
difference in CMHC per diem costs from 2003 to 2004 was 25 percent. 
This trimming approach resulted in a combined CMHC and hospital-based 
PHP median per diem cost of $176. We also trimmed the CMHC claims from 
the CY 2003 data to see how trimming aberrant data would affect the 
combined hospital/CMHC median per diem cost. We found that trimming the 
claims from the CMHCs with a 25 percent difference in per diem cost 
from CY 2003 to CY 2004 reduced the $289 median per diem cost to $218.
    We believe it is important to eliminate aberrant data and we 
believe trimming certain CMHC data would provide an incentive for CMHCs 
to stabilize their charges so that we could use their data in future 
updates of the PHP APC. However, we believe that the trimming methods 
described above would also result in an unacceptably large decrease in 
payment. In addition, the trimming method we used was based on 
percentage change in cost per day, and may not have identified all the 
CMHCs that may have manipulated their charges in order to receive more 
outlier payments, for example, CMHCs with high charges and no reduction 
in charges compared to CY 2003.
    Although we prefer to use both CMHC and hospital data to establish 
the PHP APC, we continue to be concerned about the volatility of the 
CMHC data. The analyses we have conducted seem to indicate that 
eliminating aberrant CMHC data results in a median per diem cost more 
in line with hospital data. We will continue to analyze the CMHC data 
in developing payment rates, however, if the data continues to

[[Page 42694]]

be unstable, we may use only hospital data in the future.
    We are considering an approach that would lessen the PHP payment 
reduction for CY 2006, yet, ensure an adequate payment amount and 
continue to ensure access to the partial hospitalization benefit for 
Medicare beneficiaries. For CY 2006, we are proposing to apply a 15-
percent reduction in the combined hospital-based and CMHC median per 
diem cost that was used to establish the CY 2005 PHP APC. That amount 
would then be scaled to be relative to the cost of a mid-level office 
visit to establish the PHP APC for CY 2006. We believe a reduction in 
the CY 2005 median per diem cost would strike an appropriate balance 
between using the best available data and providing adequate payment 
for a program that often spans 5-6 hours a day. We believe 15 percent 
is an appropriate reduction because it recognizes decreases in median 
per diem costs in both the hospital data and the CMHC data, and also 
reduces the risk of any adverse impact on access to these services that 
might result from a large single-year rate reduction. However, we would 
propose that the reduction in payments for PHP be a transitional 
measure, and will continue to monitor CMHC costs and charges for these 
services and work with CMHCs to improve their reporting so that 
payments can be calculated based on better empirical data, consistent 
with the approach we have used to calculate payments in other areas of 
the OPPS.
    To apply the methodology, we would reduce $289 (the CY 2005 
combined hospital-based and CMHC median per diem cost) by 15 percent, 
resulting in a combined median per diem cost of $245.65. After scaling, 
we are proposing the resulting APC amount for PHP of $240.51 for CY 
2006, of which $48.10 is the beneficiary's coinsurance. We will 
continue to analyze the data to determine whether there is a more 
targeted approach that would allow use of the CMHC and hospital PHP 
claims data to establish the final PHP rate for CY 2006.
3. Proposed Separate Threshold for Outlier Payments to CMHCs
    In the November 7, 2003 final rule with comment period (68 FR 
63469), we indicated that, given the difference in PHP charges between 
hospitals and CMHCs, we did not believe it was appropriate to make 
outlier payments to CMHCs using the outlier percentage target amount 
and threshold established for hospitals. There was a significant 
difference in the amount of outlier payments made to hospitals and 
CMHCs for PHP. Further analysis indicated the use of OPPS outlier 
payments for CMHCs was contrary to the intent of the general OPPS 
outlier policy. Therefore, for CYs 2004 and 2005, we established a 
separate outlier threshold for CMHCs. We designated a portion of the 
estimated 2.0 percent outlier target amount specifically for CMHCs, 
consistent with the percentage of projected payments to CMHCs under the 
OPPS in each of those years, excluding outlier payments.
    As stated in the November 15, 2004 final rule with comment period, 
CMHCs were projected to receive 0.6 percent of the estimated total OPPS 
payments in CY 2005 (69 FR 65848). The CY 2005 CMHC outlier threshold 
is met when the cost of furnishing services by a CMHC exceeds 3.5 times 
the PHP APC payment amount. The current outlier payment percentage is 
50 percent of the amount of costs in excess of the threshold.
    CMS and the Office of the Inspector General are continuing to 
monitor the excessive outlier payments to CMHCs. As previously stated 
in section II.B.2. above, we used CY 2004 claims data to calculate the 
proposed CY 2006 per diem payment. These data show the effect of the 
separate outlier threshold for CMHCs that was effective January 1, 
2004. During CY 2004, the separate outlier threshold for CMHCs resulted 
in $1.8 million in outlier payments to CMHCs, within the 2.0 percent of 
total OPPS payments identified for CMHCs. In CY 2003, more than $30 
million was paid to CMHCs in outlier payments. We believe this 
difference in outlier payments indicates that the separate outlier 
threshold for CMHCs has been successful in keeping outlier payments to 
CMHCs in line with the percentage of OPPS payments made to CMHCs.
    As noted in section II.H. of this preamble, for CY 2006, we are 
proposing to set the target for hospital outpatient outlier payments at 
1.0 percent of total OPPS payments. We are also proposing to allocate a 
portion of that 1.0 percent, 0.006 percent (or 0.006 percent of total 
OPPS payments), to CMHCs for PHP services. As discussed in section 
II.G. below, we are proposing a dollar threshold in addition to an APC 
multiplier threshold for hospital OPPS outlier payments. However, 
because PHP is the only APC for which CMHCs may receive payment under 
the OPPS, we would not expect to redirect outlier payments by imposing 
a dollar threshold. Therefore, we are not proposing a dollar threshold 
for CMHC outliers. We are proposing to set the outlier threshold for 
CMHCs for CY 2006 at 3.45 percent times the APC payment amount and the 
CY 2006 outlier payment percentage applicable to costs in excess of the 
threshold at 50 percent. As we did with the hospital outlier threshold, 
we used hospital charge inflation factor to inflate charges to CY 2006.

C. Proposed Conversion Factor Update for CY 2006

(If you choose to comment on issues in this section, please include 
the caption ``Conversion Factor'' at the beginning of your comment.)

    Section 1833(t)(3)(C)(ii) of the Act requires us to update the 
conversion factor used to determine payment rates under the OPPS on an 
annual basis. Section 1833(t)(3)(C)(iv) of the Act provides that, for 
CY 2006, the update is equal to the hospital inpatient market basket 
percentage increase applicable to hospital discharges under section 
1886(b)(3)(B)(iii) of the Act.
    The forecast of the hospital market basket increase for FY 2006 
published in the IPPS proposed rule on May 4, 2005 is 3.2 percent (70 
FR 23384). To set the OPPS proposed conversion factor for CY 2006, we 
increased the CY 2005 conversion factor of $56.983, as specified in the 
November 15, 2004 final rule with comment period (69 FR 65842), by 3.2 
percent.
    In accordance with section 1833(t)(9)(B) of the Act, we further 
adjusted the conversion factor for CY 2005 to ensure that the revisions 
we are making to our updates by means of the wage index are made on a 
budget-neutral basis. We calculated a proposed budget neutrality factor 
of 1.002015212 for wage index changes by comparing total payments from 
our simulation model using the FY 2006 IPPS proposed wage index values 
to those payments using the current (FY 2005) IPPS wage index values. 
In addition, to accommodate the proposed rural adjustment discussed in 
section II.G. of this preamble, we calculated a proposed budget 
neutrality factor of 0.99652023 by comparing payments with the rural 
adjustment to those without. For CY 2006, allowed pass-through payments 
are estimated to decrease to 0.05 percent of total OPPS payments, down 
from 0.1 percent in CY 2005. The proposed conversion factor is also 
adjusted by the difference in estimated pass-through payments of 0.05 
percent. Finally, decreasing proposed payments for outliers to 1.0 
percent of total payments returned 1.0 percent to the conversion 
factor.
    The proposed market basket increase update factor of 3.2 percent 
for CY 2006, the required wage index budget neutrality adjustment of 
approximately 1.002015212, the return of 1.0 percent

[[Page 42695]]

in total payments from a reduced outlier target, the 0.05 percent 
adjustment to the pass-through estimate, and the adjustment for the 
proposed rural payment adjustment of 0.99652023 result in a proposed 
conversion factor for CY 2006 of $59.350.

D. Proposed Wage Index Changes for CY 2006

(If you choose to comment on issues in this section, please include 
the caption ``Wage Index'' at the beginning of your comment.)

    Section 1833(t)(2)(D) of the Act requires the Secretary to 
determine a wage adjustment factor to adjust, for geographic wage 
differences, the portion of the OPPS payment rate and the copayment 
standardized amount attributable to labor and labor-related cost. This 
adjustment must be made in a budget neutral manner. As we have done in 
prior years, we are proposing to adopt the IPPS wage indices and extend 
these wage indices to TEFRA hospitals that participate in the OPPS but 
not the IPPS.
    As discussed in section II.A. of this preamble, we standardize 60 
percent of estimated costs (labor-related costs) for geographic area 
wage variation using the IPPS wage indices that are calculated prior to 
adjustments for reclassification to remove the effects of differences 
in area wage levels in determining the OPPS payment rate and the 
copayment standardized amount.
    As published in the original OPPS April 7, 2000 final rule (65 FR 
18545), OPPS has consistently adopted the final IPPS wage indices as 
the wage indices for adjusting the OPPS standard payment amounts for 
labor market differences. As initially explained in the September 8, 
1998 OPPS proposed rule, we believed and continue to believe that using 
the IPPS wage index as the source of an adjustment factor for OPPS is 
reasonable and logical, given the inseparable, subordinate status of 
the hospital outpatient within the hospital overall. In accordance with 
section 1886(d)(3)(E) of the Act, the IPPS wage index is updated 
annually. In this proposed rule, we are proposing to use the proposed 
FY 2006 hospital IPPS wage index published in the Federal Register on 
May 4, 2005 (70 FR 23550 through 23581), and as corrected and posted on 
the CMS Web site, to determine the wage adjustments for the OPPS 
payment rate and the copayment standardized amount for CY 2006. In 
accordance with our established policy, we are proposing to use the FY 
2006 final version of these wage indices to determine the wage 
adjustments and copayment standardized amount that we will publish in 
our final rule for CY 2006.
    We note that the FY 2006 IPPS wage indices continue to reflect a 
number of changes implemented in FY 2005 as a result of the new OMB 
standards for defining geographic statistical areas, the implementation 
of an occupational mix adjustment as part of the wage index, and new 
wage adjustments provided for under Pub. L. 108-173. The following is a 
brief summary of the proposed changes in the FY 2005 IPPS wage indices, 
continued for FY 2006, and any adjustments that we are proposing 
applying to the OPPS for CY 2006. We refer the reader to the FY 2006 
IPPS proposed rule (70 FR 23367 through 23384, May 4, 2005) for a 
detailed discussion of the changes to the wage indices.)
    1. The proposed continued use of the new Core Based Statistical 
Areas (CBSAs) issued by the Office of Management and Budget (OMB) as 
revised standards for designating geographical statistical areas based 
on the 2000 Census data, to define labor market areas for hospitals for 
purposes of the IPPS wage index. The OMB revised standards were 
published in the Federal Register on December 27, 2000 (65 FR 82235), 
and OMB announced the new CBSAs on June 6, 2003, through an OMB 
bulletin. In the FY 2005 hospital IPPS final rule, CMS adopted the new 
OMB definitions for wage index purposes. In the FY 2006 IPPS proposed 
rule, we again stated that hospitals located in MSAs would be urban and 
hospitals that are located in Micropolitan Areas or Outside CBSAs would 
be rural. To help alleviate the decreased payments for previously urban 
hospitals that became rural under the new MSA definitions, we allowed 
these hospitals to maintain their assignment to the MSA where they 
previously had been located for the 3-year period from FY 2005 through 
FY 2007. To be consistent with IPPS, we will continue the policy we 
began in CY 2005 of applying the same criterion to TEFRA hospitals paid 
under the OPPS but not under the IPPS and to maintain that MSA 
designation for determining a wage index for the specified period. 
Beginning in FY 2008, these hospitals will receive their statewide 
rural wage index, although those hospitals paid under the IPPS will be 
eligible to apply for reclassification. In addition to this ``hold 
harmless'' provision, the FY 2005 IPPS final rule implemented a one-
year transition for hospitals that experienced a decrease in their FY 
2005 wage index compared to their FY 2004 wage index due solely to the 
changes in labor market definitions. These hospitals received 50 
percent of their wage indices based on the new MSA configurations and 
50 percent based on the FY 2004 labor market areas. In the FY 2006 IPPS 
proposed rule, we discussed the cessation of the one-year transition 
and proposed that hospitals receive 100 percent of their wage index 
based upon the new CBSA configurations beginning in FY 2006. Again, for 
the sake of consistency with IPPS, we also are proposing that TEFRA 
hospitals would receive 100 percent of their wage index based upon the 
new CBSA configurations beginning in FY 2006.
    2. We again proposed to apply the proposed occupational mix 
adjustment for FY 2006 IPPS to 10-percent of the average hourly wage 
and leave 90 percent of the average hourly wage unadjusted for 
occupational mix. As noted in the FY 2006 IPPS proposed rule, we are, 
essentially, using the same CMS Wage Index Occupational Mix Survey and 
Bureau of Labor Statistics data to calculate the adjustment. Because 
there are no significant differences between the FY 2005 and the FY 
2006 occupational mix survey data and results, we believe it is 
appropriate to adopt the IPPS rule and apply the same occupational mix 
adjustment to 10 percent of the proposed FY 2006 wage index.
    3. The reclassifications of hospitals to geographic areas for 
purposes of the wage index. For purposes of the OPPS wage index, we are 
proposing to adopt all of the IPPS reclassifications proposed for FY 
2006, including reclassifications that the Medicare Geographic 
Classification Review Board (MGCRB) approved under the one-time appeal 
process for hospitals under section 508 of Pub. L. 108-173. We note 
that section 508 reclassifications will terminate March 31, 2007.
    4. The proposed continuation of an adjustment to the wage index to 
reflect the ``out-migration'' of hospital employees who reside in one 
county but commute to work in a different county with a higher wage 
index, in accordance with section 505 of Pub. L. 108-173 (FY 2006 IPPS 
proposed rule (70 FR 23381 and 23382, May 4, 2005)). Hospitals paid 
under the IPPS located in the qualifying section 505 ``out-migration'' 
counties receive a wage index increase unless they have already been 
reclassified under section 1886(d)(10) of the Act, redesignated under 
section 1886(d)(8)(B) of the Act, or reclassified under section 508. As 
discussed in the FY 2006 IPPS proposed rule, we proposed that 
reclassified hospitals not receive the out-migration adjustment unless 
they waive their reclassified

[[Page 42696]]

status. For OPPS purposes, we are continuing our policy from CY 2005 to 
apply the same 505 criterion to TEFRA hospitals paid under the OPPS but 
not paid under the IPPS. Because TEFRA hospitals cannot reclassify 
under sections 1886(d)(8) and 1886(d)(10) of the Act or section 508, 
they are eligible for the out-migration adjustment. Therefore, TEFRA 
hospitals located in a qualifying section 505 county will also receive 
an increase to their wage index under OPPS. Addendum L shows the 
hospitals, including TEFRA hospitals, that we currently believe will 
receive the out-migration adjustment. However, because we are proposing 
to adopt the final FY 2006 IPPS wage index, we will adopt any changes 
in a hospital's classification status that would make them either 
eligible or ineligible for the out-migration adjustment.
    The following proposed FY 2006 IPPS wage indices that were 
published in the May 4, 2005 Federal Register (70 FR 23550 through 
2323581) are reprinted as Addenda in this OPPS proposed rule: Addendum 
H--Wage Index for Urban Areas; Addendum I--Wage Index for Rural Areas; 
Addendum J--Wage Index for Hospitals That Are Reclassified; Addendum 
K--Puerto Rico Wage Index by CBSA; Addendum L--Out-Migration Wage 
Adjustment; Addendum M--Hospital Reclassifications and Redesignations 
by Individual Hospital and CBSA; Addendum N--Hospital Reclassifications 
and Redesignations by Individual Hospital under Section 508 of Pub. L. 
108-173; and Addendum O--Hospitals Redesignated as Rural Under Section 
1886(d)(8)(E) of the Act. We are proposing to use these FY 2006 IPPS 
indices, as they are finalized, to adjust the payment rates and 
coinsurance amounts that we will publish in the OPPS final rule for CY 
2006.
    With the exception of reclassifications resulting from the 
implementation of the one-time appeal process under section 508 of Pub. 
L. 108-173, all changes to the wage index resulting from geographic 
labor market area reclassifications or other adjustments must be 
incorporated in a budget neutral manner. Accordingly, in calculating 
the OPPS budget neutrality estimates for CY 2006, we have included the 
wage index changes that result from MGCRB reclassifications, 
implementation of section 505 of Pub. L. 108-173, and other refinements 
made in the FY 2006 IPPS proposed rule, such as the hold harmless 
provision for hospitals changing status from urban to rural under the 
new CBSA geographic statistical area definitions. However, section 508 
set aside $900 million to implement the section 508 reclassifications. 
We considered the increased Medicare payments that the section 508 
reclassifications would create in both the IPPS and OPPS when we 
determined the impact of the one-time appeal process. Because the 
increased OPPS payments already counted against the $900 million limit, 
we did not consider these reclassifications when we calculated the OPPS 
budget neutrality adjustment.

E. Proposed Statewide Average Default Cost-to-Charge Ratios

(If you choose to comment on issues in this section, please include 
the caption ``Cost-to-Charge Ratios'' at the beginning of your 
comment.)

    CMS uses CCRs to determine outlier payments, payments for pass-
through devices, and monthly interim transitional corridor payments 
under the OPPS. Some hospitals do not have a valid CCR. These hospitals 
include, but are not limited to, hospitals that are new and have not 
yet submitted a cost report, hospitals that have a CCR that falls 
outside predetermined floor and ceiling thresholds for a valid CCR, or 
hospitals that have recently given up their all-inclusive rate status. 
Last year we updated the default urban and rural CCRs for CY 2005 in 
our final rule published on November 15, 2004 (69 FR 65821 through 
65825). We are proposing to update the default ratios using the most 
recent cost report data for CY 2006.
    We calculated the proposed statewide default CCRs using the same 
CCRs that we use to adjust charges to costs on claims data. Table 3 
lists the proposed CY 2006 default urban and rural CCRs by State. These 
CCRs are the ratio of total costs to total charges from each provider's 
most recently submitted cost report, for those cost centers relevant to 
outpatient services. We also adjusted these ratios to reflect final 
settled status by applying the differential between settled to 
submitted costs and charges from the most recent pair of settled to 
submitted cost reports.
    The majority of submitted cost reports, 80.79 percent, were for CY 
2003. We only used valid CCRs to calculate these default ratios. That 
is, we removed the CCRs for all-inclusive hospitals, CAHs, and 
hospitals in Guam and the U.S. Virgin Islands because these entities 
are not paid under the OPPS, or in the case of all-inclusive hospitals, 
because their CCRs are suspect. We further identified and removed any 
obvious error CCRs and trimmed any outliers. We limited the hospitals 
used in the calculation of the default CCRs to those hospitals that 
billed for services under the OPPS during CY 2003.
    Finally, we calculated an overall average CCR, weighted by a 
measure of volume, for each State except Maryland. This measure of 
volume is the total lines on claims and is the same one that we use in 
our impact tables. For Maryland, we used an overall weighted average 
CCR for all hospitals in the nation as a substitute for Maryland CCRs, 
which appear in Table 3. Very few providers in Maryland are eligible to 
receive payment under the OPPS, which limits the data available to 
calculate an accurate and representative CCR. The overall decrease in 
default statewide CCRs can be attributed to the general decline in the 
ratio between costs and charges widely observed in the cost report 
data.

F. Expiring Hold Harmless Provision for Transitional Corridor Payments 
for Certain Rural Hospitals

    When the OPPS was implemented, every provider was eligible to 
receive an additional payment adjustment (transitional corridor 
payment) if the payments it received for covered OPD services under the 
OPPS were less than the payments it would have received for the same 
services under the prior reasonable cost-based system (section 
1833(t)(7) of the Act). Section 1833(t)(7) of the Act provides that the 
transitional corridor payments are temporary payments for most 
providers, with two exceptions, to ease their transition from the prior 
reasonable cost-based payment system to the OPPS system. Cancer 
hospitals and children's hospitals receive the transitional corridor 
payments on a permanent basis. Section 1833(t)(7)(D)(i) of the Act 
originally provided for transitional corridor payments to rural 
hospitals with 100 or fewer beds for covered OPD services furnished 
before January 1, 2004. However, section 411 of Pub. L. 108-173 amended 
section 1833(t)(7)(D)(i) of the Act to extend these payments through 
December 31, 2005, for rural hospitals with 100 or fewer beds. Section 
411 also extended the transitional corridor payments to sole community 
hospitals located in rural areas for services furnished during the 
period that begins with the provider's first cost reporting period 
beginning on or after January 1, 2004, and ends on December 31, 2005. 
Accordingly, the authority for making transitional corridor payments 
under section 1833(t)(7)(D)(i) of the Act, as amended by section 411 of 
Pub . L. 108-173, will expire for rural hospitals having 100 or fewer 
beds and sole community hospitals located in rural areas on December 
31, 2005. For CY 2006, transitional corridor payments will continue to 
be available to cancer and children's hospitals. (We note that the 
succeeding section II.G. of this preamble discusses an additional 
provision of section 411 of Pub. L. 108-173 that related to a study to 
determine appropriate adjustment to payments for rural hospitals under 
the OPPS beginning January 2006.)

G. Proposed Adjustment for Rural Hospitals

(If you choose to comment on issues in this section, please include 
the caption ``Rural Hospital Adjustment'' at the beginning of your 
comment.)

    Section 411 of Pub. L. 108-173 added a new paragraph (13) to 
section 1833(t) of the Act. New section 1833(t)(13)(A) specifically 
instructs the Secretary to conduct a study to determine if rural 
hospital outpatient costs exceed urban hospital outpatient costs. 
Moreover, under new section 1833(t)(13)(B) of the Act, the Secretary is 
given authorization to provide an appropriate adjustment to rural 
hospitals by January 1, 2006, if rural hospital costs are determined to 
be greater than urban hospital costs.
    To conduct the study required under section 1833(t)(13)(A), as 
added by section 411 of Pub. L. 108-173, we believe that a simple 
comparison of unit costs is insufficient because the costs faced by 
hospitals, whether urban or rural, will be a function of many factors. 
These include the local labor supply, and the complexity and volume of 
services provided. Therefore, we used regression analysis to study 
differences in the outpatient cost per unit between rural and urban 
hospitals in order to compare costs after accounting for the influence 
of these other factors.
    Our regression analysis included all 4,077 hospitals billing under 
OPPS for which we could model accurate cost per unit estimates. For 
each hospital, total outpatient costs and descriptive information were 
derived from CY 2004 Medicare claims and the hospital's most recently 
submitted cost report. The description of claims used, our methodology 
for creating costs from charges, and a description of the specific 
hospitals included in our modeling are discussed in section II.A. of 
this preamble. We excluded separately payable drugs and biologicals, 
and clinical laboratory services paid on a fee schedule from our 
analysis. We excluded the 49 hospitals in Puerto Rico because their 
wage indices and unit costs are so different that they would have 
skewed results. Finally, we excluded facilities whose unit outpatient 
costs were outside of 3 standard deviations from the geometric mean 
unit outpatient cost.
    Total unit outpatient cost for each hospital was calculated by 
dividing total outpatient cost by the total number of APC units 
discounted for the joint performance of multiple procedures. (See 
section II.G.2. below for a definition of discounted units.) We modeled 
both explanatory and payment regression models. In an ``explanatory 
model'' approach, all variables that are hypothesized to be important 
determinants of cost are included in the cost regression, whether or 
not they are going to be used as payment adjustments. In a ``payment 
model'' approach, the only independent variables included in the cost 
regression are those variables that are used as payment adjustments. 
The regression

[[Page 42699]]

equations for both models were specified in double logarithmetic form. 
The dependent variable in the explanatory regression equation was unit 
outpatient cost. The dependent variable in the payment regressions was 
standardized unit outpatient costs, that is, unit outpatient costs 
adjusted to reflect payment by dividing through by the provider's 
service-mix index which was adjusted by the provider's wage index. The 
service-mix index is a measure of the resource intensity of services 
provided by each hospital. Both regression equation models included 
quantitative independent variables transformed into natural logarithms 
and categorical independent variables. Categorical independent (dummy) 
variables included hospital characteristics such as rural location or 
type of hospital (short stay or specialty hospital).
1. Factors Contributing to Unit Cost Differences Between Rural 
Hospitals and Urban Hospitals
    In considering potential independent variables that might explain 
differences in unit outpatient costs between urban and rural hospitals, 
we determined that several factors would be important:
     First, unit outpatient costs are expected to vary directly 
with the prices of inputs used to produce outpatient services, 
especially labor. Wage rates tend to be lower in rural areas than in 
urban areas.
     Second, there may be economies of scale in producing 
outpatient services, which imply that unit costs will vary inversely 
with the volume of outpatient services provided.
     Third, independent of the volume of outpatient services, 
hospitals that provide more complex outpatient services are expected to 
have higher unit costs than hospitals with less complex service-mixes. 
Typically, greater complexity involves a combination of higher 
equipment and labor costs. Rural hospitals usually have less volume and 
perform less complex services than urban hospitals.
     Fourth, the size of a hospital may influence the volume 
and service-mix of outpatient services. Large hospitals generally 
provide a wider range of more complex services than do small hospitals. 
Large hospitals may also have larger volumes in ancillary departments 
that are shared between outpatient and inpatient services, and as a 
result, benefit from greater economies of scale than do small 
hospitals. Rural hospitals tend to be smaller than urban hospitals. Our 
primary measure of outpatient volume is units of APCs, which only 
reflects the volume of Medicare services paid under the outpatient PPS. 
This measure does not include the inpatient utilization of shared 
ancillary departments or non-Medicare outpatient services. For all 
these reasons, it seems appropriate to include a broader measure of 
facility size in the explanatory regression model. Therefore, as 
explained below, we used the total number of facility beds to measure 
facility size. Unit outpatient costs may be positively or negatively 
related to facility size depending on whether complexity effects or 
scale economies are more important.
2. Explanatory Variables
    We used the hospital wage index as our measure of labor input 
prices. To reflect the complexity of outpatient services, we used a 
service-mix index defined as the ratio of the number of discounted 
units weighted by APC relative weights divided by the number of 
unweighted discounted units. Discounted units are the total number of 
units after we adjust for the multiple procedure reduction of 50 
percent that applies to payment for surgical services when two surgical 
procedures are performed during the same operative session and for 
selected radiology procedures, as proposed (see section XIV. of the 
preamble). For example, if a procedure is paid at 100 percent of 
payment 1,000 times and the same procedure is paid at 50 percent of 
payment 100 times, the discounted units for that procedure equal 1,050 
units (the sum of 1,000 units at full payment plus 100 units at 50 
percent payment). We then calculate the total weight for that procedure 
by multiplying the discounted units by the full weight for the 
procedure. The service-mix index reflects the average APC weight of 
each facility's outpatient services. Outpatient service volume was 
measured as the total number of unweighted discounted units. We used 
the total number of facility beds as the broader measure of facility 
size. We also included categorical variables to indicate the types of 
specialty hospitals that participate in OPPS, specifically cancer, 
children's, long-term care, rehabilitation, and psychiatric hospitals. 
Finally, we included a categorical variable for rural/urban location to 
capture variation unexplained by the other independent variables in the 
model. For all of the rural dummy variables discussed below, urban 
hospitals are the reference group. Table 4 provides descriptive 
statistics for the dependent variable and key independent variables by 
urban and rural status. Without controlling for the other influences on 
per unit cost, rural hospitals have lower cost per unit than urban 
hospitals. However, when standardized for the service-mix wage indices, 
average unit costs are nearly identical between urban and rural 
hospitals

3. Results
    Overall, all rural hospitals give some indication of having higher 
cost per unit, after controlling for labor input prices, service-mix 
complexity, volume, facility size, and type of hospital. In an 
explanatory model regressing unit costs on all independent variables 
discussed above, the coefficient for the rural categorical variable was 
0.024 (p=0.058), which suggests that rural hospitals are approximately 
2.4 percent more costly than urban hospitals after accounting for the 
impact of other explanatory variables. The results of this regression 
appear in Table 5. This regression demonstrated reasonably good 
explanatory power with an adjusted R2 of 0.53 (rounded). Adjusted R2 is 
the percentage of variation in the dependent variable explained by the 
independent variables and is a standard measure of how well the 
regression model fits the data. The regression coefficients of the key 
explanatory variables all move in the expected direction: positive for 
the wage index, indicating that rural hospitals can be expected to have 
lower unit outpatient costs because they tend to be located in areas 
with lower wage rates; positive for the outpatient service-mix index, 
consistent with the hypothesis that rural hospitals' less complex 
outpatient service-mixes result in lower unit costs than those of the 
typical urban hospital; negative for outpatient service volume, 
implying that, on average, rural hospitals' lower service volumes are a 
source of higher unit cost compared to urban hospitals; and positive 
for the facility size variable (beds), suggesting that facility size is 
more reflective of complexity than any economies of scale. The rural 
dummy variable has a coefficient of 0.02414. If the unit costs of rural 
hospitals are the same as the unit costs of urban hospitals, the 
probability of observing a value as extreme as or more extreme than 2.4 
percent would be approximately 6 percent or less. This explanatory 
regression model provides some evidence that outpatient services 
provided by rural hospitals are more costly than outpatient services 
provided by urban hospitals, but the evidence is weak. The payment 
regression that accompanies this explanatory model indicates an 
adjustment for all rural hospitals of 3.7 percent.

 Note: Coefficients of all quantitative variables are elasticities since both the dependent variable, unit
  outpatient cost, and all quantitative independent variables were in natural logarithms. To calculate
  percentage differences for categorical variables, their coefficients must be raised to the power, e, the base
  of natural logarithms.
1 A t value is an indicator of our degree of confidence that the regression coefficient is different from zero,
  taking into account the statistical variability of the estimated coefficient.
2 A p value is the probability of observing the specific t value when the estimated coefficient is zero. The t
  values greater than 2 and less than -2 indicate a probability less than 5 percent, p-value< 0.05, that the
  estimated coefficient is zero.

    In order to assess whether the small difference in costs was 
uniform across rural hospitals or whether all of the variation was 
attributable to a specific class of rural hospitals, we included more 
specific categories of rural hospitals in our explanatory regression 
analysis. We divided rural hospitals into rural SCHs, rural hospitals 
with less than 100 beds that are not rural sole community hospitals, 
and other rural hospitals. The first two categories of rural hospitals 
are currently eligible for payments under the expiring hold-harmless 
provision. Because it appears that rural SCHs are responsible for the 
variation in rural hospital costs, we then collapsed the last remaining 
categories in an ``all other'' rural hospital category.
    We found that rural SCHs demonstrated significantly higher cost per 
unit than urban hospitals after controlling for labor input prices, 
service-mix complexity, volume, facility size, and type of hospital. 
The results of this regression appear in Table 6. With the exception of 
the new rural variables, the independent variables have the same sign 
and significance as in Table 5. Rural SCHs have a positive and 
significant coefficient; all other rural hospitals do not. The rural 
SCH ``dummy'' variable has an explanatory regression coefficient of 
0.05668 and an observed probability that the coefficient is zero of 
less than 0.001. If the unit costs of rural SCHs are the same as those 
of urban hospitals, the probability of observing a value as extreme or 
more extreme than 5.8 percent would be less than 0.1 percent. 
Accordingly, we have determined that rural SCHs are more costly than 
urban hospitals, holding all other variables constant. Notably, we 
observed no significant difference between all other rural hospitals 
and urban hospitals.

  values greater than 2 and less than -2 indicate a probability less than 5 percent, p-value < 0.05, that the
  estimated coefficient is zero.

    Based on the above analysis and as noted in the explanatory 
regression in Table 6, we believe that a payment adjustment for rural 
SCHs is warranted. The accompanying payment regression, also appearing 
in Table 6, indicates a cost impact of 6.6 percent. Thus, in accordance 
with the authority provided in section 1833(t)(13)(B) of the Act, as 
added by section 411 of Pub. L. 108-173, we are proposing a 6.6 percent 
payment increase for rural SCHs for CY 2006. This adjustment would 
apply to all services and procedures paid under the OPPS, excluding 
drugs and biologicals. We note that this adjustment would be budget 
neutral, and would be applied before calculating outliers and 
coinsurance. We may revisit this adjustment in the future.
    Additional descriptive statistics are available on the CMS Web 
site.

H. Proposed Hospital Outpatient Outlier Payments

(If you choose to comment on issues in this section, please include 
the caption ``Outlier Payments'' at the beginning of your comment.)

    Currently, the OPPS pays outlier payments on a service-by-service 
basis. For CY 2005, the outlier threshold is met when the cost of 
furnishing a service or procedure by a hospital exceeds 1.75 times the 
APC payment amount and exceeds the APC payment rate plus a $1,175 fixed 
dollar threshold. We introduced a fixed dollar threshold in CY 2005 in 
addition to the traditional multiple threshold to better target 
outliers to those high cost and complex procedures where a very costly 
case could present a hospital with significant financial loss. If a 
provider meets both of these conditions, the multiple threshold and the 
fixed dollar threshold, the outlier payment is calculated as 50 percent 
of the amount by which the cost of furnishing the service exceeds 1.75 
times the APC payment rate. For CMHCs, the outlier threshold is met 
when the cost of furnishing a service or procedure by a CMHC exceeds 
3.5 times the APC payment rate. If a CMHC provider meets this 
condition, the outlier payment is calculated as 50 percent of the 
amount by which the cost exceeds 3.5 times the APC payment rate.
    As explained in our CY 2005 final rule (69 FR 65844), we set our 
projected target for aggregate outlier payments at 2.0 percent of 
aggregate total payments under OPPS. Our outlier thresholds were set so 
that estimated CY 2005 aggregate outlier payments would equal 2.0 
percent of aggregate total payments under OPPS.
    For CY 2006, we are proposing to set our projected target for 
aggregate outlier payments at 1.0 percent of aggregate total payments 
under OPPS. A portion of that 1.0 percent, an amount equal to .006 
percent of aggregate total payments under OPPS, would be allocated to 
CMHCs for partial hospitalization program service outliers. In its 
March 2004 Report, MedPAC recommended that Congress should eliminate 
the outlier policy under the outpatient prospective payment system. 
While this would require a statutory change, many of the reasons cited 
by MedPAC for the elimination of the outlier policy are equally 
applicable to any reduction in the size of the percentage of total 
payments dedicated to outlier payments, including the following: the 
narrow definition of many of the services provided in hospital 
outpatient departments suggests that variability in costs should not be 
great; the distribution of outlier payments benefits some hospital 
groups more than others; the outlier policy is susceptible to 
``gaming'' through charge inflation; and, the OPPS is the only 
ambulatory payment system with an outlier policy.
    In order to ensure that estimated CY 2006 aggregate outlier 
payments would equal 1.0 percent of estimated aggregate total payments 
under OPPS, we are proposing that the outlier threshold be modified so 
that outlier payments are triggered when the cost of furnishing a 
service or procedure by a hospital exceeds 1.75 times the APC payment 
amount and exceeds the APC payment rate plus a $1,575 fixed dollar 
threshold. We choose to modify the fixed dollar threshold to target 1.0 
percent of estimated aggregate total payment under OPPS and not modify 
the current 1.75 multiple to further our policy of targeting outlier 
payments to complex and expensive procedures with sufficient 
variability to pose a financial risk for hospitals. Modifying the 
multiple would do less to target outlier payments to complex and 
expensive procedures. For example, if we were to establish a multiple 
of 2.00 rather than 1.75, then an APC with a payment rate of $20,000 
would see the outlier threshold associated with the multiple increase 
from $35,000 to $40,000. Raising the fixed dollar threshold to

[[Page 42702]]

$1,575 only increases the threshold for expensive procedures by $400. 
For this reason, we believe it is more appropriate to focus the 
modification necessary to target 1.0 percent of aggregate OPPS payments 
on the fixed dollar threshold and increase it from $1,175 in CY 2005 to 
our proposed $1,575 in CY 2006 and have the multiple threshold remain 
at 1.75.
    For CY 2006, the outlier threshold for CMHCs is met when the cost 
of furnishing a service or procedure by a CMHC exceeds 3.45 times the 
APC payment rate. If a CMHC provider meets this condition, the outlier 
payment is calculated as 50 percent of the amount by which the cost 
exceeds 3.45 times the APC payment rate.
    The following is an example of an outlier calculation for CY 2006 
under our proposed policy. A hospital charges $26,000 for a procedure. 
The APC payment for the procedure is $3,000, including a rural 
adjustment, if applicable. Using the provider's cost-to-charge ratio of 
0.30, the estimated cost to the hospital is $7,800. To determine 
whether this provider is eligible for outlier payments for this 
procedure, the provider must determine whether the cost for the service 
exceeds both the APC outlier cost threshold (1.75 x APC payment) and 
the fixed dollar threshold ($1,575 + APC payment). In this example, the 
provider meets both criteria:
    (1) $7,800 exceeds $5,250 (1.75 x $3,000)
    (2) $7,800 exceeds $4,575 ($1,575 + $3,000)
    To calculate the outlier payment, which is 50 percent of the amount 
by which the cost of furnishing the service exceeds 1.75 times the APC 
rate, subtract $5,250 (1.75 x $3,000) from $7,800 (resulting in 
$2,550). The provider is eligible for 50 percent of the difference, in 
this case $1,275 ($2,550/2). The formula is (cost -(1.75 x APC payment 
rate))/2.

I. Calculation of the Proposed National Unadjusted Medicare Payment

(If you choose to comment on issues in this section, please include 
the caption ``Payment Rate for APCs'' at the beginning of your 
comment.)

    The basic methodology for determining prospective payment rates for 
OPD services under the OPPS is set forth in existing regulations at 
Sec.  419.31 and Sec.  419.32. The payment rate for services and 
procedures for which payment is made under the OPPS is the product of 
the conversion factor calculated in accordance with section II.C. of 
this proposed rule, and the relative weight determined under section 
II.A. of this proposed rule. Therefore, the national unadjusted payment 
rate for APCs contained in Addendum A to this proposed rule and for 
payable HCPCS codes in Addendum B to this proposed rule (Addendum B is 
provided as a convenience for readers) was calculated by multiplying 
the proposed CY 2006 scaled weight for the APC by the proposed CY 2006 
conversion factor.
    However, to determine the payment that would be made in a calendar 
year under the OPPS to a specific hospital for an APC for a service 
other than a drug, in a circumstance in which the multiple procedure 
discount does not apply, we take the following steps:
    Step 1. Calculate 60 percent (the labor-related portion) of the 
national unadjusted payment rate. Since initial implementation of the 
OPPS, we have used 60 percent to represent our estimate of that portion 
of costs attributable, on average, to labor. (Refer to the April 7, 
2000 final rule with comment period (65 FR 18496 through 18497), for a 
detailed discussion of how we derived this percentage.)
    Step 2. Determine the wage index area in which the hospital is 
located and identify the wage index level that applies to the specific 
hospital. The wage index values assigned to each area reflect the new 
geographic statistical areas as a result of revised OMB standards 
(urban and rural) to which hospitals would be assigned for FY 2006 
under the IPPS, reclassifications through the Medicare Classification 
Geographic Review Board, section 1866(d)(8)(B) ``Lugar'' hospitals, and 
section 401 of Pub. L. 108-173, and the reclassifications of hospitals 
under the one-time appeals process under section 508 of Pub. L. 108-
173. Assess whether the previous MSA-based wage index is higher than 
the CBSA-based wage index, and, if higher, apply a 50/50 blend. The 
wage index values include the occupational mix adjustment described in 
section II.D. of this proposed rule that was developed for the IPPS.
    Step 3. Adjust the wage index of hospitals located in certain 
qualifying counties that have a relatively high percentage of hospital 
employees who reside in the county, but who work in a different county 
with a higher wage index, in accordance with section 505 of Pub. L. 
108-173. Addendum K contains the qualifying counties and the proposed 
wage index increase developed for the IPPS. This step is to be followed 
only if the hospital has chosen not to accept reclassification under 
Step 2 above.
    Step 4. Multiply the applicable wage index determined under Steps 2 
and 3 by the amount determined under Step 1 that represents the labor-
related portion of the national unadjusted payment rate.
    Step 5. Calculate 40 percent (the nonlabor-related portion) of the 
national unadjusted payment rate and add that amount to the resulting 
product of Step 4. The result is the wage index adjusted payment rate 
for the relevant wage index area.
    Step 6. If a provider is a sole community hospital, as defined in 
Sec.  419.92, and located in a rural area, as defined in Sec.  
412.63(b) or is treated as being located in a rural area under section 
1886(d)(8)(E) of the Act, multiply the wage index adjusted payment rate 
by 1.066 to calculate the total payment.

J. Proposed Beneficiary Copayments for CY 2006

(If you choose to comment on issues in this section, please include 
the caption ``Beneficiary Copayment'' at the beginning of your 
comment.)
1. Background
    Section 1833(t)(3)(B) of the Act requires the Secretary to set 
rules for determining copayment amounts to be paid by beneficiaries for 
covered OPD services. Section 1833(t)(8)(C)(ii) of the Act specifies 
that the Secretary must reduce the national unadjusted copayment amount 
for a covered OPD service (or group of such services) furnished in a 
year in a manner so that the effective copayment rate (determined on a 
national unadjusted basis) for that service in the year does not exceed 
specified percentages. For all services paid under the OPPS in CY 2006, 
and in calendar years thereafter, the specified percentage is 40 
percent of the APC payment rate. Section 1833(t)(3)(B)(ii) of the Act 
provides that, for a covered OPD service (or group of such services) 
furnished in a year, the national unadjusted coinsurance amount cannot 
be less than 20 percent of the OPD fee schedule amount.
2. Proposed Copayment for CY 2006
    For CY 2006, we are proposing to determine copayment amounts for 
new and revised APCs using the same methodology that we implemented for 
CY 2004 (see the November 7, 2003 OPPS final rule with comment period, 
68 FR 63458). The proposed unadjusted copayment amounts for services 
payable under the OPPS that would be effective January 1, 2006, are 
shown in Addendum A and Addendum B of this proposed rule.

[[Page 42703]]

3. Calculation of the Proposed Unadjusted Copayment Amount for CY 2006
    To calculate the unadjusted copayment amount for an APC group, take 
the following steps:
    Step 1. Calculate the beneficiary payment percentage for the APC by 
dividing the APC's national unadjusted copayment by its payment rate. 
For example, using APC 0001, $9.95 is 40 percent of $24.89.
    Step 2. Calculate the wage adjusted payment rate for the APC, for 
the provider in question, as indicated in section II.I. above.
    Step 3. Multiply the percentage calculated in Step 1 by the payment 
rate calculated in Step 2. The result is the wage adjusted copayment 
amount for the APC.

III. Proposed Ambulatory Payment Classification (APC) Group Policies

A. Background

    Section 1833(t)(2)(A) of the Act requires the Secretary to develop 
a classification system for covered hospital outpatient services. 
Section 1833(t)(2)(B) provides that this classification system may be 
composed of groups of services, so that services within each group are 
comparable clinically and with respect to the use of resources. In 
accordance with these provisions, we developed a grouping 
classification system, referred to as the Ambulatory Payment 
Classification Groups (or APCs), as set forth in Sec.  419.31 of the 
regulations. We use Level I and Level II HCPCS codes and descriptors to 
identify and group the services within each APC. The APCs are organized 
such that each group is homogeneous both clinically and in terms of 
resource use. Using this classification system, we have established 
distinct groups of surgical, diagnostic, and partial hospitalization 
services, and medical visits. We also have developed separate APC 
groups for certain medical devices, drugs, biologicals, 
radiopharmaceuticals, and devices of brachytherapy.
    We have packaged into each procedure or service within an APC group 
the cost associated with those items or services that are directly 
related and integral to performing a procedure or furnishing a service. 
Therefore, we do not make separate payment for packaged items or 
services. For example, packaged items and services include: use of an 
operating, treatment, or procedure room; use of a recovery room; use of 
an observation bed; anesthesia; medical/surgical supplies; 
pharmaceuticals (other than those for which separate payment may be 
allowed under the provisions discussed in section V. of this preamble); 
and incidental services such as venipuncture. Our packaging methodology 
is discussed in section II.A. of this proposed rule.
    Under the OPPS, we pay for hospital outpatient services on a rate-
per-service basis that varies according to the APC group to which the 
service is assigned. Each APC weight represents the median hospital 
cost of the services included in that APC relative to the median 
hospital cost of the services included in APC 0601 (Mid-Level Clinic 
Visits). The APC weights are scaled to APC 0601 because a mid-level 
clinic visit is one of the most frequently performed services in the 
outpatient setting.
    Section 1833(t)(9)(A) of the Act requires the Secretary to review 
the components of the OPPS not less than annually and to revise the 
groups and relative payment weights and make other adjustments to take 
into account changes in medical practice, changes in technology, and 
the addition of new services, new cost data, and other relevant 
information and factors. Section 1833(t)(9)(A) of the Act, as amended 
by section 201(h) of the BBRA of 1999, also requires the Secretary, 
beginning in CY 2001, to consult with an outside panel of experts to 
review the APC groups and the relative payment weights (the APC Panel 
recommendations for CY 2006 OPPS and our responses to them are 
discussed in sections III.B. and III.C.4. of this preamble).
    Finally, as discussed earlier, section 1833(t)(2) of the Act 
provides that, subject to certain exceptions, the items and services 
within an APC group cannot be considered comparable with respect to the 
use of resources if the highest median (or mean cost, if elected by the 
Secretary) for an item or service in the group is more than 2 times 
greater than the lowest median cost for an item or service within the 
same group (referred to as the ``2 times rule''). We use the median 
cost of the item or service in implementing this provision. The statute 
authorizes the Secretary to make exceptions to the 2 times rule in 
unusual cases, such as low-volume items and services.

B. Proposed Changes--Variations Within APCs

(If you choose to comment on issues in this section, please include 
the caption ``2 Times Rule'' at the beginning of your comment.)
1. Application of the 2 Times Rule
    In accordance with section 1833(t)(2) of the Act and Sec.  419.31 
of the regulations, we annually review the items and services within an 
APC group to determine with respect to comparability of the use of 
resources if the median of the highest cost item or service within an 
APC group is more than 2 times greater than the median of the lowest 
cost item or service within that same group (``2 times rule''). We make 
exceptions to this limit on the variation of costs within each APC 
group in unusual cases such as low-volume items and services. The 
statute provides no exception in the case of a drug or biological that 
has been designated as an orphan drug under section 526 of the Federal 
Food, Drug, and Cosmetic Act because these drugs are assigned to 
individual APC's.
    During the APC Panel's February 2005 meeting, we presented median 
cost and utilization data for the period of January 1, 2004, through 
September 30, 2004, concerning a number of APCs that violate the 2 
times rule and asked the APC Panel for its recommendation. After 
carefully considering the information and data we presented, the APC 
Panel recommended moving a total of 65 HCPCS codes from their currently 
assigned APC to a different APC to resolve the 2 times rule violations. 
Of the 65 HCPCS code reassignments recommended by the APC Panel, we 
concur with 58 of the recommended reassignments. Therefore, we are 
proposing to reassign these HCPCS codes as shown in Table 7.

    The seven HCPCS code movements that the APC Panel recommended, but 
upon further review we are proposing not to accept, are discussed 
below. We include in our discussion our proposal specific to each of 
them to resolve the 2 times rule violations.
    a. APC 0146: Level I Sigmoidoscopy, APC 0147: Level II 
Sigmoidoscopy, APC 0428: Level III Sigmoidoscopy.
    APCs 0146 and 0147 were exceptions to the 2 times rule in CY 2005. 
Our analysis of these two APCs based on the most current CY 2004 data 
revealed greater violations of the 2 times rule and changing relative 
frequencies of simple and complex procedures in these two APCs. Thus, 
for CY 2006, the APC Panel assisted us in reconfiguring these two APCs 
into three related APCs to resolve the two times violations and improve 
their clinical and resource homogeneity based on the most current 
hospital claims data and to remove these APCs from the list of 
exceptions. The APC Panel recommended moving CPT codes 45303 
(Proctosigmoidoscopy dilate) and 45305 (Proctosigmoidoscopy w/bx) from 
APC 0147 to APC 0146 because the median cost for these codes appeared 
too high, and was likely based primarily on aberrant CY 2004 claims. In 
addition, the APC Panel recommended that CMS move CPT code 45309 
(Proctosigmoidoscopy removal) from APC 0147 to a new proposed APC 0428.

[[Page 42705]]

Based on the results of our review of several years of claims data and 
our study of hospital resource homogeneity, we disagree that these 
claims data are aberrant. We are proposing to move CPT codes 45303 and 
45305 to APC 0147 and to keep CPT 45309 in APC 0147, to resolve the 2 
times rule violation.
    b. APC 0342: Level I Pathology, APC 0433: Level II Pathology, APC 
0343: Level III Pathology.
    To resolve a 2 times rule violation, the APC Panel recommended 
moving CPT codes 88108 (Cytopath, concentrate tech) and 88112 
(Cytopath, cell enhance tech) from APC 0343 to a proposed new APC 0433. 
The APC Panel also recommended moving CPT codes 88319 (Enzyme 
histochemistry) and 88321 (Microslide consultation) from APC 0342 to a 
proposed new APC 0433. Based on the results of our review of several 
years of claims data and the study of hospital resource homogeneity, we 
are proposing a different way to resolve the 2 times rule violation: We 
are proposing to place CPT codes 88319 and 88112 in APC 0343 and to 
place CPT codes 88108 and 88321 in APC 0433.
2. Proposed Exceptions to the 2 Times Rule
    As discussed earlier, we may make exceptions to the 2 times limit 
on the variation of costs within each APC group in unusual cases such 
as low-volume items and services. Taking into account the APC changes 
that we are proposing for CY 2006 based on the APC Panel 
recommendations discussed in section III.B.1. of this preamble and the 
use of CY 2004 claims data to calculate the median cost of procedures 
classified in the APCs, we reviewed all the APCs to determine which 
APCs would not meet the 2 times limit. We used the following criteria 
to decide whether to propose exceptions to the 2 times rule for 
affected APCs:
     Resource homogeneity
     Clinical homogeneity
     Hospital concentration
     Frequency of service (volume)
     Opportunity for upcoding and code fragments.
    For a detailed discussion of these criteria, refer to the April 7, 
2000 OPPS final rule with comment period (65 FR 18457).
    Table 8 below contains the APCs that we are proposing to exempt 
from the 2 times rule based on the criteria cited above. In cases in 
which a recommendation of the APC Panel appeared to result in or allow 
a violation of the 2 times rule, we generally accepted the APC Panel's 
recommendation because these recommendations were based on explicit 
consideration of resource use, clinical homogeneity, hospital 
specialization, and the quality of the data used to determine the APC 
payment rates that we are proposing for CY 2006. The median cost for 
hospital outpatient services for these and all other APCs can be found 
on the CMS Web site: http//http://www.cms.hhs.gov.

C. New Technology APCs

(If you choose to comment on issues in this section, please include 
the caption ``New Technology APCs'' at the beginning of your 
comment.)
1. Background
    In the November 30, 2001 final rule (66 FR 59903), we finalized 
changes to the time period a service was eligible for payment under a 
New Technology APC. Beginning in CY 2002, we retain services within New 
Technology APC groups until we gather sufficient claims data to enable 
us to assign the service to a clinically appropriate APC. This policy 
allows us to move a service from a New Technology APC in less than 2 
years if sufficient data are available. It also allows us to retain a 
service in a New Technology APC for more than 3 years if sufficient 
data upon which to base a decision for reassignment have not been 
collected.
2. Proposed Refinement of New Technology Cost Bands
    In the November 7, 2003 final rule with comment period, we last 
restructured the New Technology APC groups to make the cost intervals 
more consistent across payment levels (68 FR 63416). We established 
payment levels in $50, $100, and $500 intervals and expanded the number 
of New Technology APCs. We also retained two parallel sets of New 
Technology APCs, one set with a status indicator of ``S'' (Significant 
Procedure, Not Discounted When Multiple) and the other set with a 
status indicator of ``T'' (Significant Procedures, Multiple Reduction 
Applies). We did this restructuring because the number of procedures 
assigned to New Technology APCs had increased, and narrower cost bands 
were necessary to avoid significant payment inaccuracies for New 
Technology services. Therefore, we dedicated two new series of APCs to 
the restructured New Technology APCs, which allowed us to narrow the 
cost bands and afforded us the flexibility to create additional bands 
as future needs dictated.
    As the number of procedures that qualify for placement in the New 
Technology APCs has continued to increase over the past 2 years, the $0 
to $50 cost band represented by ``S'' status APC 1501 (New Technology, 
Level I, $0-$50) and ``T'' status APC 1538 (New Technology, Level I, 
$0-$50) spans too broad of a cost interval to accurately represent the 
lower costs of an ever-increasing number of procedures that qualify for 
New Technology payment. Therefore, we are proposing to refine this cost 
band to five $10 increments, resulting in the creation of an additional 
10 New Technology APCs to accommodate the two parallel sets of New 
Technology APCs, one set with a status indicator of ``S'' and the other 
set with a status indicator of ``T.'' We are also proposing to 
eliminate the two $0 to $50 cost band New Technology APCs 1501 and 
1538, so that the cost bands of all New Technology APCs would continue 
to be mutually exclusive. Table 9 contains a listing of the 10 
additional New Technology APCs that we are proposing for CY 2006.

                                      $50).
----------------------------------------------------------------------------------------------------------------

    As we explained in the November 30, 2001 final rule (66 FR 59897), 
we generally keep a procedure in the New Technology APC to which it is 
initially assigned until we have collected data sufficient to enable us 
to move the procedure to a clinically appropriate APC. However, in 
cases where we find that our original New Technology APC assignment was 
based on inaccurate or inadequate information, or where the New 
Technology APCs are restructured, we may, based on more recent resource 
utilization information (including claims data) or the availability of 
refined New Technology APC bands, reassign the procedure or service to 
a different New Technology APC that most appropriately reflects its 
cost. Therefore, we are proposing to discontinue New Technology APCs 
1501 and 1538, and reassign the procedures currently assigned to them 
to proposed New Technology APCs 1491 through 1500. Table 10 summarizes 
these proposed New Technology APC reassignments.

----------------------------------------------------------------------------------------------------------------

3. Proposed Requirements for Assigning Services to New Technology APCs
    In the April 7, 2000 final rule (65 FR 18477), we created a set of 
New Technology APCs to pay for certain new technology services under 
the OPPS. We described a group of criteria for use in determining 
whether a service is eligible for assignment to a New Technology APC. 
We subsequently modified this set of criteria in our November 30, 2001 
final rule (66 FR 59897 to 59901), effective January 1, 2002. These 
modifications were based on changes in the data (we were no longer 
required to use 1996 data to set payment rates) and on our continuing 
experience with the assignment of services to New Technology APCs.
    Based on our history of reviewing applications for New Technology 
APC assignments under the OPPS, we have encountered situations where 
there is extremely limited clinical experience with new technology 
services regarding their use and efficacy in the typical Medicare 
population. In some cases, there may be ambiguity regarding how the new 
technology services fit within the standard coding framework for 
established procedures, and there may be no specific coding available 
for the new technology services in other settings or for use by other 
payers. Nevertheless, applicants requesting assignment of services to 
New Technology APCs request that we provide billing and payment 
mechanisms under the OPPS for the new technology services through the 
establishment of codes, descriptors, and payment rates. As stated in 
section I.F. of this preamble, we remain committed to the overarching 
goal of ensuring that Medicare beneficiaries have timely access to the 
most effective new medical treatments and technologies in clinically 
appropriate settings. We believe that our current New Technology APC 
assignment process helps to assure such access, and that an enhancement 
to the New Technology service application process may further encourage 
appropriate dissemination of and Medicare beneficiary access to new 
technology services.
    We are interested in promoting review of the coding, clinical use, 
and efficacy of new technology services by the greater medical 
community through our New Technology service application and review 
process for the OPPS. Therefore, in addition to our current information 
requirements at the time of application, we are proposing to require 
that an application for a code for a new technology service be 
submitted to the American Medical Association's (AMA's) CPT Editorial 
Panel before we accept a New Technology APC application for review. 
This will not change our current criteria for assignment of a service 
to a New Technology APC. This requirement will encourage timely review 
by the wider medical community as CMS is reviewing the service for 
possible new coding and assignment to a New Technology APC under the 
OPPS. There is only one CPT code application that is used by applicants 
requesting consideration for either Category I or III codes. We would 
accept either a Category I or Category III code application to the CPT 
Editorial Panel. The application requests relevant clinical information 
regarding new services, including their appropriate use and the patient 
populations expected to benefit from the services which will provide us 
with useful additional information. CPT code applications are reviewed 
by the CPT Editorial Panel, whose members bring diverse clinical 
expertise to that review. We believe that consideration by the CPT 
Editorial Panel may facilitate appropriate dissemination of the new 
technology services across delivery settings and may bring to light 
other needed coding changes or clarifications. We are further proposing 
that a copy of the submitted CPT application be filed with us as part 
of the application for a New Technology APC assignment under the OPPS, 
along with CPT's letter acknowledging or accepting the coding 
application. We remind the public that we do not consider an 
application complete until all informational requirements are provided. 
In addition, we remind the public that when we assign a new service a 
HCPCS code and provide for payment under the OPPS, these actions do not 
imply coverage by the Medicare program, but indicate only how the 
procedure or service may be paid if covered by the program. Fiscal 
intermediaries must determine whether a service meets all program 
requirements for coverage, for example, that it is reasonable and 
necessary to treat the beneficiary's condition and whether it is 
excluded from payment. CMS may also make National Coverage 
Determinations (NCDs) on new technology procedures.
4. Proposed Movement of Procedures From New Technology APCs to Clinical 
APCs
    The procedures discussed below represent New Technology services 
for which we believe we have sufficient data to reassign to a 
clinically appropriate APC.
a. Proton Beam Therapy
(If you choose to comment on issues in this section, please include 
the caption ``Proton Beam Therapy'' at the beginning of your 
comment.)

    In the August 16, 2004 proposed rule (69 FR 50467), we proposed to 
reassign CPT codes 77523 (Proton treatment delivery, intermediate) and 
77525 (Proton treatment delivery, complex) from New Technology APC 1511 
(New Technology, Level XI, $900-$1,000) to clinical APC 0419 (Proton 
Beam Therapy, Level II). In response to this proposal, we received 
numerous comments urging that we maintain CPT codes 77523 and 77525 in 
New Technology APC 1511 at a payment rate of $950 for CY 2005, arguing 
that the proposed payment rate of $678.31 for

[[Page 42708]]

CY 2005 would halt diffusion of this technology and negatively impact 
patient access to this cancer treatment. Commenters explained that the 
low volume of claims submitted by only two facilities provided volatile 
and insufficient data for movement into the proposed clinical APC 0419. 
They further explained that the extraordinary capital expense of 
between $70 and $125 million and high operating costs of a proton beam 
facility necessitate adequate payment for this service to protect the 
financial viability of this emerging technology.
    In the November 15, 2004 final rule with comment period (69 FR 
65719 through 65720), we considered the concerns expressed by numerous 
commenters that patient access to proton beam therapy might be impeded 
by a significant reduction in OPPS payment. Therefore, we set the CY 
2005 payment rate for CPT codes 77523 and 77525 by calculating a 50/50 
blend of the median cost for intermediate and complex proton beam 
therapies of $690.45 derived from CY 2003 claims and the CY 2004 New 
Technology payment rate of $950. We used the result of this calculation 
($820) to assign intermediate and complex proton beam therapies (CPT 
codes 77523 and 77525) to New Technology APC 1510 (New Technology--
Level X ($800-$900) for a blended payment rate of $850 for CY 2005.
    Our examination of the CY 2004 claims data has revealed a second 
year of a stable, albeit modest, number of claims on which to set the 
CY 2006 payment rates for CPT codes 77523 and 77525. However, unlike 
the median of $690.45 for the CY 2005 Level II proton beam radiation 
therapy clinical APC containing CPT codes 77523 and 77525 derived from 
the CY 2003 claims data, the median for a comparable Level II proton 
beam radiation therapy clinical APC is $934.46 derived from CY 2004 
claims data. This more recent median appears to more accurately reflect 
the significant capital expense and high operating costs of a proton 
beam therapy facility, and supports patient access to proton beam 
therapy. Therefore, we are proposing to move CPT codes 77523 and 77525 
from New Technology APC 1510 to clinical APC 0667 (Level II Proton Beam 
Radiation Therapy) based on a median cost of $934.46 for CY 2006.
b. Stereotactic Radiosurgery

(If you choose to comment on issues in this section, please include 
the caption ``Stereotactic Radiosurgery'' at the beginning of your 
comment.)

    In a correction to the November 7, 2003 final rule with comment 
period, issued on December 31, 2003 (68 FR 75442), we considered a 
commenter's request to combine HCPCS codes G0242 (Cobalt 60-based 
stereotactic radiosurgery planning) and G0243 (Cobalt 60-based 
stereotactic radiosurgery delivery) into a single procedure code in 
order to capture the costs of this treatment in single procedure claims 
because the majority of patients receive the planning and delivery of 
this treatment on the same day. We responded to the commenter's request 
by explaining that several other commenters stated that HCPCS code 
G0242 was being misused to code for the planning phase of linear 
accelerator-based stereotactic radiosurgery planning. Because the 
claims data for HCPCS code G0242 represented costs for linear 
accelerator-based stereotactic radiosurgery planning (due to misuse of 
the code), in addition to Cobalt 60-based stereotactic radiosurgery 
planning, we were uncertain of how to combine these data with HCPCS 
code G0243 to determine an accurate payment rate for a combined code 
for planning and delivery of Cobalt 60-based stereotactic radiosurgery.
    In consideration of the misuse of HCPCS code G0242 and the 
potential for causing greater confusion by combining HCPCS codes G0242 
and G0243 into a single procedure code, for CY 2004 we created a 
planning code for linear accelerator-based stereotactic radiosurgery 
(HCPCS code G0338) to distinguish this service from Cobalt 60-based 
stereotactic radiosurgery planning. We maintained both HCPCS codes 
G0242 and G0243 for the planning and delivery of Cobalt 60-based 
stereotactic radiosurgery, consistent with the use of the two G-codes 
for planning (HCPCS code G0338) and delivery (HCPCS codes G0173, G0251, 
G0339, G0340, as applicable) of each type of linear accelerator-based 
stereotactic radiosurgery (SRS). We indicated that we intended to 
maintain these new codes in their current New Technology APCs until we 
had sufficient hospital claims data reflecting the costs of the 
services to consider moving them to clinical APCs.
    During the February 2005 APC Panel meeting, the APC Panel discussed 
the clinical and resource cost similarities between planning for Cobalt 
60-based and linear accelerator-based SRS. The APC Panel also discussed 
the use of CPT codes instead of specific G-codes to describe the 
services involved in SRS planning, noting the clinical similarities in 
radiation treatment planning regardless of the mode of treatment 
delivery. Acknowledging the possible need for CMS to separately track 
planning for SRS, the APC Panel eventually recommended that we create a 
single HCPCS code to encompass both Cobalt 60-based and linear 
accelerator-based SRS planning. However, a hospital association and 
other presenters at the APC Panel meeting urged that we discontinue the 
use of G-codes for SRS planning, and instead, recognize the current CPT 
codes that describe the specific component services involved in SRS 
planning to reduce the burden on hospitals of maintaining duplicative 
codes for the same services to accommodate different payers. Lastly, 
one presenter urged that we combine HCPCS codes G0242 (Cobalt 60-based 
stereotactic radiosurgery planning) and G0243 (Cobalt 60-based 
stereotactic radiosurgery delivery) into a single procedure code to 
reflect that the majority of patients receive the planning and delivery 
of this treatment on the same day as a single fully integrated service.
    The APC Panel recommended that we make no changes to the coding or 
APC placement of SRS delivery codes G0173, G0243, G0251, G0339, and 
G0340 for CY 2006. We first established the above full group of 
delivery codes in 2004, so we have only one year of hospital claims 
data reflecting costs of the services. In addition, presenters to the 
APC Panel described current ongoing deliberations amongst interested 
professional societies around the descriptions and coding for SRS. The 
APC Panel and presenters suggested that we wait for the outcome of 
these deliberations prior to making any significant changes to SRS 
delivery coding or payment rates.
    In an effort to balance the recommendations of the APC Panel with 
the recommendations of presenters at the APC Panel meeting, in 
accordance with the APC Panel recommendations, we are proposing to make 
no changes to the APC placement of the following SRS treatment delivery 
codes for CY 2006: HCPCS codes G0173, G0243, G0251, G0339, and G0340.
    We recognize concerns expressed by some presenters urging that we 
discontinue the use of the G-codes for SRS planning, and instead, 
recognize the current CPT codes that describe the specific component 
services involved in SRS planning to reduce the burden on hospitals of 
maintaining duplicative codes for the same services to accommodate 
different payers. In addition, we have no need to separately track SRS 
planning services, which share clinical and resource homogeneity with 
other radiation treatment planning

[[Page 42709]]

services described by current CPT codes.
    When HCPCS code G0242 was established for SRS planning, several 
radiology planning services were considered in determining its APC 
placement. In the November 30, 2001 final rule, in which we described 
our determination of the total cost for SRS planning based on our 
claims experience, we added the median costs of the following CPT codes 
that we found to be regularly billed with SRS delivery (CPT code 61793 
in the available hospital data): 77295, 77300, 77370, and 77315. Our 
examination of the costs from the CY 2004 claims data for the above-
mentioned CPT codes closely approximates the CY 2004 median costs 
reported for HCPCS codes G0242 and G0338. The APC median costs for the 
above-mentioned CPT codes based on the CY 2004 claims data total 
$1,297, while the median cost for HCPCS code G0242 is $1,366 and the 
median cost for HCPCS code G0338 is $1,100 based on the CY 2004 claims 
data. In addition, three of the above-mentioned CPT codes are included 
on the proposed bypass list for CY 2006, so we would not anticipate 
that the billing of these codes on the same day as an SRS treatment 
service would cause significant problems with multiple bills for SRS 
services. Therefore, we are proposing to discontinue HCPCS codes G0242 
and G0338 for the reporting of charges for SRS planning under the OPPS, 
and to instruct hospitals to bill charges for SRS planning using all of 
the available CPT codes that most accurately reflect the services 
provided.
    We acknowledge one APC Panel presenter's concern that the coding 
structure of Cobalt 60-based SRS, using either the current SRS planning 
G code or the appropriate CPT codes for planning services as we are 
proposing for CY 2006, may not necessarily reflect the same day, 
integrated Cobalt 60-based SRS service furnished to the majority of 
patients receiving Cobalt 60-based SRS. Thus, we are seeking public 
comment on the clinical, administrative, or other concerns that could 
arise if we were to bundle Cobalt 60-based SRS planning services, 
currently reported using HCPCS code G0242 and proposed for CY 2006 to 
be billed using the appropriate CPT codes for planning services, into 
the Cobalt 60-based SRS treatment service, currently reported under the 
OPPS using HCPCS code G0243. Under such a scenario, the SRS treatment 
service described by HCPCS code G0243 would be placed in a higher 
paying New Technology APC to reflect payment for the costs of the SRS 
planning and delivery as an integrated service. Hospitals would be 
prohibited from billing other radiation planning services along with 
the Cobalt 60-based SRS treatment delivery code. In contrast to Cobalt 
60-based SRS coding, we would not consider bundling the planning for 
linear accelerator-based SRS with the treatment delivery services, 
given the various timeframes for planning that may occur with linear 
accelerator-based SRS.
c. Other Services in New Technology APCs
(If you choose to comment on issues in this section, please include 
the caption ``Other New Technology Services'' at the beginning of 
your comment.)

    Other than proton beam and stereotactic radiosurgery services, 
there are 10 procedures currently assigned to New Technology APCs for 
which we have data adequate to support their assignment to clinical 
APCs. We are proposing to reassign these procedures to clinically 
appropriate APCs, using CY 2004 claims data to establish median costs 
on which payments would be based. These procedures and their proposed 
APC assignments are displayed below in Table 11.

----------------------------------------------------------------------------------------------------------------

    We are proposing to move these 10 procedures to new or established 
clinical APCs that contain services that exhibit clinical and resource 
homogeneity. HCPCS code C9713 (Noncontact laser vaporization of 
prostate, including coagulation control of intraoperative and post-
operative bleeding) is similar to CPT code 52647 (Noncontact laser 
coagulation of prostate, including control of postoperative bleeding, 
complete (vasectomy, meatotomy, cystourethroscopy, urethral calibration 
and/or dilation, and internal urethrotomy are included)) and CPT code 
52648 (Contact laser vaporization with or without transurethral 
resection of prostate, including control of postoperative bleeding, 
complete (vasectomy, meatotomy, cystourethroscopy, urethral calibration 
and/or dilation, and internal urethrotomy are included)) with respect 
to their clinical characteristics and hospital resource utilization. 
However, instead of mapping HCPCS code C9713 to APC 163 (Level IV 
Cystourethroscopy and other Genitourinary Procedures), where CPT codes 
52647 and 52648 are currently mapped for CY 2005, we are proposing to 
create a Level V APC for Cystourethroscopy and Other Genitourinary 
Procedures. These codes are more clinically sound in this new Level V 
APC. We are also proposing to map CPT codes 52647 and 52648 to this new 
Level V APC. In addition, we are proposing to move CPT codes 50080 and 
50081 from APC 0163 to this new Level V APC, since they are similar 
clinically and use similar hospital resources. We believe that this 
configuration would improve homogeneity as well as result in a

[[Page 42710]]

clinically coherent Level V APC, where the procedures utilize similar 
hospital resources.

D. Proposed APC-Specific Policies

1. Hyperbaric Oxygen Therapy (APC 0659)

(If you choose to comment on issues in this section, please include 
the caption ``Hyperbaric Oxygen'' at the beginning of your comment.)

    When hyperbaric oxygen therapy (HBOT) is prescribed for promoting 
the healing of chronic wounds, it typically is prescribed on average 
for 90 minutes, which would be billed using multiple units of HBOT to 
achieve full body hyperbaric oxygen therapy. In addition to the 
therapeutic time spent at full hyperbaric oxygen pressure, treatment 
involves additional time for achieving full pressure (descent), 
providing air breaks to prevent neurological and other complications 
from occurring during the course of treatment, and returning the 
patient to atmospheric pressure (ascent). The OPPS recognizes HCPCS 
code C1300 (Hyperbaric oxygen under pressure, full body chamber, per 30 
minute interval) for HBOT provided in the hospital outpatient setting.
    We explained in the August 16, 2004 proposed rule (69 FR 50495) 
that our CY 2003 claims data revealed that many providers were 
improperly reporting charges for 90 to 120 minutes under only one unit 
rather than three or four units of HBOT. This inaccurate coding 
resulted in an inflated median cost of $177.96 for HBOT, derived using 
single service claims and ``pseudo'' single service claims. Because of 
these single claims coding anomalies, we proposed to calculate a ``per 
unit'' median cost for APC 0659, using only multiple units or multiple 
occurrences of HBOT, excluding claims with only one unit of HBOT and 
excluding packaged costs. To convert HBOT charges to costs, we used the 
CCR from the respiratory therapy cost center when available; otherwise, 
we used the hospital's overall CCR. Using this ``per unit'' 
methodology, we proposed a median cost for APC 0659 of $82.91 for CY 
2005.
    In the November 15, 2004 final rule with comment period (69 FR 
65758), we agreed with commenters that there was sufficient evidence 
that the CCR for HBOT was not reflected solely in the respiratory 
therapy cost center; rather, the CCR for HBOT was reflected in a 
variety of cost centers. Therefore, we calculated a ``per unit'' median 
of $93.26 for HBOT, using only multiple units or multiple occurrences 
of HBOT and each hospital's overall CCR.
    Our examination of the CY 2004 single procedure claims filed for 
HCPCS code C1300 revealed similar coding anomalies to those encountered 
in the CY 2003 single procedure claims data. Therefore, for CY 2006 
ratesetting, we recalculated a ``per unit'' median cost for HCPCS code 
C1300 using only multiple units or multiple occurrences of HBOT and 
each hospital's overall CCR, which is the same methodology we used for 
setting the CY 2005 payment rate for HBOT. Excluding claims with only 
one unit of HBOT, we used a total of 26,556 claims to calculate the 
median for APC 0659 for CY 2006. Applying the methodology described 
above, we are proposing a median cost for APC 0659 of $93.71 for CY 
2006.
2. Allergy Testing (APC 0370)

(If you choose to comment on issues in this section, please include 
the caption ``Allergy Testing'' at the beginning of your comment.)

    A number of providers have expressed confusion related to the 
reporting of units for allergy testing described by CPT codes 95004 
through 95078. Most of the CPT codes in the code range are assigned to 
APC 0370 (Allergy Tests) for the CY 2005 OPPS. Nine of these CPT codes 
assigned to APC 0370 instruct providers to specify the number of tests 
or use the singular word ``test'' in their descriptors, while five of 
these CPT codes assigned to APC 0370 do not contain such an instruction 
or do not contain ``tests'' or ``testing'' in their descriptors. Some 
providers have stated that the lack of clarity related to the reporting 
of units has resulted in erroneous reporting of charges for multiple 
allergy tests under one unit (that is, ``per visit'') for the CPT codes 
that instruct providers to specify the number of tests.
    In light of the variable hospital billing that may be inconsistent 
with the CPT code descriptors, we have examined carefully the CY 2004 
single and multiple procedure claims data for the allergy test codes 
that reside in APC 0370 to set the CY 2006 payment rates. Our 
examination of the CY 2004 claims data revealed that many of the 
services for which providers billed multiple units of an allergy test 
reported a consistent charge for each unit. Conversely, some providers 
that billed only a single unit of an allergy test reported a charge 
many times greater than the ``per test'' charge reported by providers 
billing multiple units of an allergy test.
    Our analysis of the claims data appears to validate reports made by 
a number of providers that the charges reported on many of the single 
procedure claims represent a ``per visit'' charge, rather than a ``per 
test'' charge, including claims for the allergy test codes that 
instruct providers to specify the number of tests. Because the OPPS 
relies only on these single procedure claims in establishing payment 
rates, we believe this inaccurate coding would have resulted in an 
inflated CY 2006 median cost of $66.44 for services that are in the CY 
2005 configuration of APC 0370.
    Therefore, we are proposing to move the allergy test CPT codes that 
instruct providers to specify the number of tests or use the singular 
word ``test'' in their descriptors from APC 0370 (Allergy Tests) to 
proposed APC 0381 (Single Allergy Tests) for CY 2006. We are proposing 
to calculate a ``per unit'' median cost for proposed APC 0381 using a 
total of 306 claims containing multiple units or multiple occurrences 
of a single CPT code. Packaging on the claims was allocated equally to 
each unit of the CPT code. Using this ``per unit'' methodology, we are 
proposing a median cost for APC 0381 of $11.37 for CY 2006. Because we 
believe the single procedure claims for the codes remaining in APC 0370 
reflect accurate coding of these services, we are proposing to use the 
standard OPPS methodology to calculate the median for APC 0370. Table 
12 below lists the proposed assignment of CPT codes to APC 0370 and 
proposed APC 0381 for CY 2006.

3. Stretta Procedure (APC 0322)

(If you choose to comment on issues in this section, please include 
the caption ``Stretta'' at the beginning of your comment.)

    CPT code 43257, effective January 1, 2005, is used for 
esophagoscopy with delivery of thermal energy to the muscle of the 
lower esophageal sphincter and/or gastric cardia for the treatment of 
gastresophageal reflux disease. This code describes the Stretta 
procedure, including use of the Stretta System and all endoscopies 
associated with the Stretta procedure. Prior to CY 2005, the Stretta 
procedure was recognized under HCPCS code C9701 in the OPPS. For the CY 
2005 OPPS, C9701 was deleted and CPT code 43257 was utilized for the 
Stretta procedure. In CY 2005, the Stretta procedure was transitioned 
from a New Technology APC to clinical APC 0422 (Level II Upper GI 
Procedures) based on several years of hospital cost data. Procedures 
within APC 0422 were similar to the Stretta procedure in terms of 
clinical characteristics and resource use.
    For CY 2006, we are proposing to use both CY 2004 single claims for 
C9701 and multiple procedure claims containing one unit of HCPCS code 
C9701 and one unit of either CPT code 43234 or CPT code 43235 to 
calculate the Stretta procedure's contribution to the median for APC 
0422. Claims reporting one endoscopy code (43234 or 43235) along with 
HCPCS code C9701 are included in the proposed median calculation 
because, in CY 2002, CMS authorized the separate and additional billing 
of a single endoscopy code with HCPCS code C9701, while CPT code 43257 
now includes all endoscopies performed during the procedure.
    Using this proposed methodology, we calculated a median for CPT 
code 43257 (HCPCS code C9701 in the CY 2004 claims data) of $1669.43. 
Using these claims in the calculation of the median cost for APC 0422, 
we calculated a median cost of $1385.77. We are proposing to use this 
methodology, applied to the more complete final rule claims set, to 
calculate the final CY 2006 OPPS median cost for APC 0422.
4. Vascular Access Procedures (APCs 0032, 0109, 0115, 0119, 0124, and 
0187)
(If you choose to comment on issues in this section, please include 
the caption ``Vascular Access Procedures'' at the beginning of your 
comment.)

    Many of the codes that currently describe vascular access 
procedures were new in the 2004 version of CPT and were assigned into 
APC groups by crosswalking the newly created CPT codes to the deleted 
codes' APC assignments. Although the new codes were implemented in 
January 2004, because of the delay between a bill being submitted to 
Medicare and when the bill data are viable for analysis, we did not 
have cost and utilization data for the new codes available for analysis 
until this year in preparation for the CY 2006 OPPS.
    Since those original APC assignments were made, we have received 
requests from the public for specific APC assignment changes. We were 
reluctant to make changes without data to support reassignments and, 
therefore, made few changes to those original APC assignments.
    As an outcome of an analysis of procedure-specific median costs and 
2 times rule violations in preparation for the CY 2006 update of the 
OPPS, we developed a new APC configuration for vascular access 
procedure codes and several other related codes. The proposed new 
assignments are supported by CY 2004 hospital claims data and are based 
on median cost and clinical considerations.
    Thus, for CY 2006, we are proposing to reassign many of the CPT 
codes that are currently in the following APCs:
     APC 0032 (Insertion of Central Venous/Arterial Catheter).
     APC 0109 (Removal of Implanted Devices).
     APC 0115 (Cannula/Access Device Procedures).
     APC 0119 (Implantation of Infusion Pump).
     APC 0124 (Revision of Implanted Infusion Pump).
     APC 0187 (Miscellaneous Placement/Repositioning).
    The configuration that we are proposing places all of the 
procedures currently assigned to APC 0187 into more clinically 
appropriate APCs. We are also proposing to reassign all of the vascular 
access procedure codes currently assigned to any of the identified APCs 
to existing or newly reconfigured clinical APCs to create more clinical 
and median cost homogeneity. As a result of the proposed reassignments, 
those APCs are comprised of a different mix of codes than is currently 
the case for the CY 2005 OPPS. There are no codes assigned to APC 0187 
because the only procedures that remained in APC 0187 after reassigning 
the vascular access procedures as we are proposing were CPT code 75940 
(X-ray placement of vein filter) and CPT code 76095 (Stereotactic 
breast biopsy), which we reassigned to more clinically appropriate 
APCs. We are proposing to reassign CPT code 75940 to APC 0297 (Level II 
Therapeutic Radiologic Procedures) and CPT code 76095 to APC 0264 
(Level II Miscellaneous Radiology Procedures).
    We are proposing to create three new APCs, APC 0621 (Level I 
Vascular Access Codes), APC 0622 (Level II Vascular Access Codes), and 
APC 0623 (Level III Vascular Access Codes) and assign procedures to 
each of these based on median cost and clinical homogeneity. We are 
also proposing to rename APCs 0109 and 0115 as follows: APC 0109 
(Removal of Implanted Devices); and APC 0115 (Cannula/Access Device 
Procedures). Table 13 displays the procedures and their current and the 
CY 2006 proposed APC assignments.

    We presented this proposal to the APC Panel at its February, 2005 
meeting. The APC Panel was supportive of the proposed reassignments and 
recommended that we make these changes. Therefore, for the stated 
reasons, we are proposing the APC modifications for CY 2006 OPPS as 
summarized in Table 13 above.

E. Proposed Addition of New Procedure Codes

(If you choose to comment on issues in this section, please include 
the caption ``New Procedure Codes'' at the beginning of your 
comment.)

    During the second quarter of CY 2005, we created 11 HCPCS codes 
that were not addressed in the November 15, 2004 final rule with 
comment period that updated the CY 2005 OPPS. We have designated the 
payment status of those codes and added them to the April update of the 
CY 2005 OPPS (Transmittal 514). The codes are shown in Table 14 below. 
In this proposed rule, we are soliciting comment on the APC assignment 
of these services.
    Further, consistent with our annual APC updating policy, we are 
proposing to assign the new HCPCS codes for CY 2006 to the appropriate 
APC's and

[[Page 42713]]

would incorporate them into our final rule for CY 2006.

IV. Proposed Payment Changes for Devices

A. Device-Dependent APCs

(If you choose to comment on issues in this section, please include 
the caption ``Device-Dependent APCs'' at the beginning of your 
comment.)

    Device-dependent APCs are populated by HCPCS codes that usually, 
but not always, require that a device be implanted or used to perform 
the procedure. For the CY 2002 OPPS, we used external data, in part, to 
establish the device-dependent APC medians used for weight setting. At 
that time, many devices were eligible for pass-through payment. For the 
CY 2002 OPPS, we estimated that the total amount of pass-through 
payments would far exceed the limit imposed by statute. To reduce the 
amount of a pro rata adjustment to all pass-through items, we packaged 
75 percent of the cost of the devices, using external data furnished by 
commenters on the August 24, 2001 proposed rule and information 
furnished on applications for pass-through payment, into the median 
cost for the device-dependent APCs associated with these pass-through 
devices. The remaining 25 percent of the cost was considered to be 
pass-through payment.
    In the CY 2003 OPPS, we determined APC medians for device-dependent 
APCs using a three pronged approach. First, we used only claims with 
device codes on the claim to set the medians for these APCs. Second, we 
used external data, in part, to set the medians for selected device-
dependent APCs by blending that external data with claims data to 
establish the APC medians. Finally, we also adjusted the median for any 
APC (whether device-dependent or not) that declined more than 15 
percent. In addition, in the CY 2003 OPPS, we deleted the device codes 
(``C'' codes) from the HCPCS file in the belief that hospitals would 
include the charges for the devices on their claims, notwithstanding 
the absence of specific codes for devices used.
    In the CY 2004 OPPS, we used only claims containing device codes to 
set the medians for device-dependent APCs and again used external data 
in a 50-percent blend with claims data to adjust medians for a few 
device-dependent codes when it appeared that the adjustments were 
important to ensure access to care. However, hospital device code 
reporting was optional.
    In the CY 2005 OPPS, which was based on CY 2003 claims data, there 
were no device codes on the claims and, therefore, we could not use 
device-coded claims in median calculations as a proxy for completeness 
of the coding and charges on the claims. For the CY 2005 OPPS, we 
adjusted device-dependent APC medians for those device-dependent APCs 
for which the CY 2005 OPPS payment median was less than 95 percent of 
the CY 2004 OPPS payment median. In these cases, the CY 2005 OPPS 
payment median was adjusted to 95 percent of the CY 2004 OPPS payment 
median. We also reinstated the device codes and made the use of the 
device codes mandatory where an appropriate code exists to describe a 
device utilized in a procedure and also implemented HCPCS code edits to 
facilitate complete reporting of the charges for the devices used in 
the procedures assigned to the device-dependent APCs.
    We are proposing to base the CY 2006 OPPS device-dependent APC 
medians on CY 2004 claims, the most current data available. In CY 2004, 
the use of device codes was optional. Thus, for the CY 2006 OPPS, we 
calculated median costs for these APCs using all single bills without 
regard to whether there was a device code on the claim. We calculated 
median costs for this set of APCs using the standard median calculation 
methodology. This methodology uses single procedure claims to set the 
median costs for the APC. We then compared these unadjusted median 
costs to the adjusted median costs that we used to set the payment 
rates for the CY 2005 OPPS. We found that 21 APCs experienced increases 
in median cost compared to the CY 2005 OPPS adjusted median costs, 1 
APC median was unchanged, 16 APCs experienced decreases in median 
costs, and 8 APCs are proposed to be reconfigured in such a way that no 
valid comparison was possible. Table 15 shows the comparison of these 
median costs.
    As we stated previously, in CY 2004, CMS reissued HCPCS codes for 
devices and asked that hospitals voluntarily code devices utilized to 
provide services. As part of our development of the proposed medians 
for this proposed rule, we examined CY 2004 claims that contained 
device codes that met our device edits, as posted on the OPPS Web site 
at http://www.cms.hhs.gov/providers/hopps/default.asp. We found that, 

in many cases, the number of claims that passed the device edits was 
quite small. To use these claims to set medians for the CY 2006 OPPS 
would mean that the medians for some of these APCs would be set based 
on very small numbers of claims, reflecting the fact that in CY 2004 
when device coding was optional under the OPPS relatively few hospitals 
chose to code for devices. For example, if we used only claims that 
passed the device code edits, the median for APC 0089 (Insertion/
Replacement of Permanent Pacemaker and Electrodes), would be based on 
34 claims that passed the device edits (0.78 percent of all claims), 
rather than on 1,934 single bills out of 4,424 total bills (43.72 
percent of all claims). Median

[[Page 42714]]

costs for insertion/replacement of a permanent pacemaker and electrodes 
developed based upon these 34 claims from a small subset of hospitals 
are unlikely to be representative of the resource costs of most 
hospitals that provided the service. Moreover, there are a few 
procedures for which no device codes are required although the 
procedures require a device to be used. For this set of services, 
subsetting the claims to those that pass the device edits does not 
change the group of single bills available for median calculation. For 
these reasons, we decided not to use only claims that passed the device 
edits to set the median costs for device-dependent APCs for the CY 2006 
OPPS.
    When we considered whether to base the weights for these APCs on 
the unadjusted median costs, we found that for 10 of the 38 APCs for 
which the APC composition is stable, basing the payment weight on the 
unadjusted median cost would result in a reduction of more than 15 
percent in the median cost for the CY 2006 OPPS compared to the CY 2005 
OPPS.
    We fully expect to use the unadjusted median costs for device-
dependent APCs as the basis of their payment weights for the CY 2007 
OPPS because device coding is required for CY 2005 and device editing 
is being implemented in CY 2005, so that all CY 2005 claims should 
reflect the costs of devices used to provide services. Nevertheless we 
recognize that a payment reduction of more than 15 percent from the CY 
2005 OPPS to the CY 2006 OPPS may be problematic for hospitals that 
provide the services contained in these APCs. Therefore, for the CY 
2006 OPPS, as we have consistently done for device-dependent APCs, we 
are proposing to adjust the median costs for the device-dependent APCs 
listed in Table 15 for which comparisons with prior years are valid to 
the higher of the CY 2006 unadjusted APC median or 85 percent of the 
adjusted median on which payment was based for the CY 2005 OPPS. This 
would result in the use of adjusted medians for 10 device-dependent 
APCs. We view this as a transitional step from the adjusted medians of 
past years to the use of unadjusted medians based solely on hospital 
claims data with device codes in future years.
    We expect that this would be the last year in which we would make 
an across the board adjustment to the median costs for these device-
dependent APCs based on comparisons to the prior year's payment 
medians. We believe that mandatory reporting of device codes for 
services furnished in CY 2005, combined with the editing of claims for 
the presence of device codes, where such codes are appropriate, would 
result in claims data that more fully reflect the relative costs of 
these services and that across the board adjustments to median costs 
for these APCs would no longer be appropriate.
    We recognize that the APC Panel recommended that CMS set a corridor 
of median costs for device-dependent APCs at no less than 90 percent of 
the CY 2005 payment median nor more than 110 percent of the CY 2005 
payment median for purposes of setting the payment rate for the CY 2006 
OPPS for these APCs. We do not believe that setting a corridor to 
control both increases and decreases in median costs is consistent with 
the use of adjusted medians as a means of transitioning hospitals to 
the use of the unadjusted claims data. The purpose of the transition is 
to moderate the rate of decline in payments so that hospitals can 
determine how to best adjust to payments based on unadjusted claims 
data. Limiting the rate of increase in payments based on such claims 
data would be inconsistent with that purpose. Therefore, we are 
proposing to adjust median costs to the greater of the median from 
claims data or 85 percent of the CY 2005 median used to set the payment 
rate in CY 2005 and not to impose a limit on the extent to which a 
median cost can increase.

B. APC Panel Recommendations Pertaining to APC 0107 and APC 0108

    The median costs for APC 0107 (Implantation of Cardioverter-
Defibrillator) and APC 0108 (Insertion/Replacement/Repair of 
Cardioverter-Defibrillator Leads and Insertion of Cardioverter-
Defibrillator) have been adjusted each year since CY 2003 when pass-
through payment expired for cardioverter-defibrillators, because the 
unadjusted medians have differed significantly from the prior year's 
payment medians. Moreover, because we use single procedure claims to 
set the median costs, the median costs for these APCs have always been 
set on a relatively small number of claims as compared to the total 
frequency of claims for the services under the OPPS. For example, for 
this CY 2006 OPPS proposed rule, the unadjusted median cost for APC 
0107 was set based on 445 single procedure claims, which is 5.5 percent 
of the 8,073 claims on which a procedure code in the APC was billed. 
Similarly, the unadjusted median cost for APC 0108 was set based on 520 
single procedure claims, which is 8.7 percent of the 6,003 claims on 
which a procedure code in the APC was billed. Commenters have 
frequently told us that using the single procedure median costs for 
these APCs does not accurately reflect the costs of the procedures 
because claims from typical clinical circumstances involving multiple 
procedures are not used to establish the medians.
    At the February 2005 APC Panel meeting, the APC Panel recommended 
that CMS package CPT codes 93640 and 93641 (electrophysiologic 
evaluation at time of initial implantation or replacement of 
cardioverter-defibrillator leads). The APC Panel recommended that we 
always package the costs for these codes because the definitions of the 
codes state that these evaluations are done at the time of lead 
implantation. Therefore, CPT codes 93640 and 93641 would never be 
correctly reported without a code in APC 0107 or APC 0108 also being 
reported. In addition, when a service assigned to APC 0107 or APC 0108 
is provided, we would expect that CPT codes 93640 or 93641 for 
electrophysiologic evaluation and testing would also be performed 
frequently, and CY 2004 claims data for services in APC 0107 and APC 
0108 confirm this. The APC Panel believed that packaging the costs of 
CPT codes 93640 and 93641 would result in more single bills available 
for setting the median costs for APC 0107 and APC 0108, and thus would 
likely yield more appropriate median costs for those APCs. Those 
medians would then include the costs of the electrophysiologic testing 
commonly performed at the time of the implantable cardioverter-
defibrillator (ICD) insertion.
    The APC Panel further recommended that CMS treat CPT code 33241 
(Subcutaneous removal of cardioverter-defibrillator) as a bypass code 
when the code appeared on the same claims with services assigned to APC 
0107 or APC 0108. The APC Panel recommended bypassing charges for this 
code only when it appeared on the same claim with codes in APC 0107 or 
APC 0108, because when a cardioverter defibrillator (ICD) is removed 
and replaced in the same operative session, it is appropriate to 
attribute all of the packaged costs on the claim to the implantation of 
the device rather than to the removal of the device. The line costs for 
CPT code 33241 that are removed from the claims in this case would be 
discarded and would not be used to set the median for APC 0105 (the APC 
in which the code is located).
    We modeled the median costs that would be calculated for APCs 0107 
and 0108, if we were to make the changes recommended by the APC Panel 
for these APCs, under four possible scenarios: (1) The cardioverter-
defibrillator device is inserted without removal or testing; (2) the 
device is inserted and tested with no removal; (3) the device is 
removed and inserted but not tested; and (4) the device is removed, 
inserted, and tested. We then compared the sum of the unadjusted median 
costs, the sum of the proposed adjusted median costs and the sum of the 
costs that we modeled using the APC Panel recommendations. These 
results are shown in Table 16 below.

    We also found that if we were to adopt the APC Panel 
recommendations for APCs 0107 and 0108 for the CY 2006 OPPS, the number 
of single bills that would be available for use in median setting would 
increase significantly, as shown in Table 17.

    In general, we believe that the recommendations of the APC Panel 
show great potential for providing a far more robust set of single 
bills for use in setting medians for APCs 0107 and 0108 and, therefore, 
for improving the accuracy of the median costs acquired from the claims 
data. However, for the CY 2006 OPPS, adopting the APC Panel 
recommendations would result in higher total payments for services 
related to cardioverter-defibrillator insertion for some possible 
clinical scenarios than under the proposed adjustment methodology but 
would result in lower total payments in other cases. Moreover, the 
effects are not identical for both APCs. Both APCs require the 
insertion of an ICD, but the codes in APC 0108 also require the repair, 
revision or insertion of leads. Because the APCs are so closely related 
clinically and both APCs include payments for expensive implanted 
cardioverter-defibrillators, we are proposing to apply the same payment 
policy to both APC 0107 and APC 0108. We would like to receive input 
from the APC Panel and from the affected parties regarding the results 
of modeling the methodology before we decide whether to implement this 
multiple procedure claim strategy for both of these APCs.
    Specifically, we are proposing to set the medians for these APCs at 
85 percent of their CY 2005 payment medians and have based our modeling 
of the scaler and the impact analysis on that proposal, although we 
believe that the APC Panel recommendations have significant merit, 
particularly when we move to complete reliance on claims data in 
updating the OPPS for CY 2007. Although we are proposing to adjust the 
median costs for these APCs in the same manner as other device-
dependent APCs, we will consider, based on the public comments, whether 
it would be appropriate to apply the multiple procedure claims 
methodology to these APCs for the CY 2006 OPPS. We look forward to 
specifically receiving public comments on the APC Panel recommendations 
regarding packaging and bypassing services frequently performed with 
procedures assigned to APC 0107 and APC 0108, with the goal of 
increasing single bills available for ratesetting in order to improve 
the accuracy of median costs based upon hospital claims.

C. Pass-Through Payments for Devices

(If you choose to comment on issues in this section, please include 
the caption ``Transitional Pass-Through Payments for Devices'' at 
the beginning of your comment.)
1. Expiration of Transitional Pass-Through Payments for Certain Devices
    Section 1833(t)(6)(B)(iii) of the Act requires that, under the 
OPPS, a category of devices be eligible for transitional pass-through 
payments for at least 2, but not more than 3 years. This period begins 
with the first date on which a transitional pass-through payment is 
made for any medical device that is described by the category. In our 
November 15, 2004 final rule with comment period (69 FR 65773), we 
specified three device categories currently in effect that would cease 
to be eligible for pass-through payment effective January 1, 2006.
    The device category codes became effective April 1, 2001, under the 
provisions of the BIPA. Prior to pass-through device categories, we 
paid for pass-through devices under the OPPS on a brand-specific basis. 
All of the initial 97 category codes that were established as of April 
1, 2001, have

[[Page 42718]]

expired; 95 categories expired after CY 2002 and 2 categories expired 
after CY 2003. All of the categories listed in Table 18, along with 
their expected expiration dates, were created since we published the 
criteria and process for creating additional device categories for 
pass-through payment on November 2, 2001 (66 FR 55850 through 55857). 
We based the expiration dates for the category codes listed in Table 18 
on the date on which a category was first eligible for pass-through 
payment.
    There are three categories for devices that would have been 
eligible for pass-through payments for at least 2 years as of December 
31, 2005. In the November 15, 2004 final rule with comment period, we 
finalized the December 31, 2005 expiration dates for these three 
categories--C1814 (Retinal tamponade device, silicone oil), C1818 
(Integrated keratoprosthesis), and C1819 (Tissue localization excision 
device). Each category includes devices for which pass-through payment 
was first made under the OPPS in CY 2003 or CY 2004.
    In the November 1, 2002 final rule, we established a policy for 
payment of devices included in pass-through categories that are due to 
expire (67 FR 66763). For CY 2003, we packaged the costs of the devices 
no longer eligible for pass-through payments into the costs of the 
procedures with which the devices were billed in CY 2001. There were 
few exceptions to this established policy (brachytherapy sources for 
other than prostate brachytherapy, which is now also separately paid in 
accordance with section 621(b)(2) of Pub. L. 108-173). For CY 2005, we 
continued to apply this policy, the same as we did in CY 2003 and 2004, 
to categories of devices that expired on December 31, 2004.
2. Proposed Policy for CY 2006
    For CY 2006, we are proposing to implement the final decision we 
made in the November 15, 2004 final rule with comment period that 
finalizes the expiration date for pass-through status for device 
categories C1814, C1818, and C1819. Therefore, as of January 1, 2006, 
we will discontinue pass-through payment for C1814, C1818, and C1819. 
In accordance with our established policy, we are proposing to package 
the costs of the devices assigned to these three categories into the 
costs of the procedures with which the devices were billed in CY 2004, 
the year of hospital claims data used for this proposed OPPS update.

D. Other Policy Issues Relating To Pass-Through Device Categories

(If you choose to comment on issues in this section, please include 
the caption ``Pass-Through Device Categories'' at the beginning of 
your comment.)
1. Provisions for Reducing Transitional Pass-Through Payments to Offset 
Costs Packaged Into APC Groups
a. Background
    In the November 30, 2001 final rule, we explained the methodology 
we used to estimate the portion of each APC payment rate that could 
reasonably be attributed to the cost of the associated devices that are 
eligible for pass-through payments (66 FR 59904). Beginning with the 
implementation of the CY 2002 OPPS quarterly update (April 1, 2002), we 
deducted from the pass-through payments for the identified devices an 
amount that reflected the portion of the APC payment amount that we 
determined was associated with the cost of the device, as required by 
section 1833(t)(6)(D)(ii) of the Act. In the November 1, 2002 interim 
final rule with comment period, we published the applicable offset 
amounts for CY 2003 (67 FR 66801).
    For the CY 2002 and CY 2003 OPPS updates, to estimate the portion 
of each APC payment rate that could reasonably be attributed to the 
cost of an associated device eligible for pass-through payment, we used 
claims data from the period used for recalibration of the APC rates. 
That is, for CY 2002 OPPS updating, we used CY 2000 claims data and for 
CY 2003 OPPS updating, we used CY 2001 claims data. For CY 2002, we 
used median cost claims data based on specific revenue centers used for 
device related costs because C-code cost data were not available until 
CY 2003. For CY 2003, we calculated a median cost for every APC without 
packaging the costs of associated C-codes for device categories that 
were billed with the APC. We then calculated a median cost for every 
APC with the costs of the associated device category C-codes that were 
billed with the APC packaged into the median. Comparing the median APC 
cost without device packaging to the median APC cost including device 
packaging enabled us to determine the percentage of the median APC cost 
that is attributable to the associated pass-through devices. By 
applying those percentages to the APC payment rates, we determined the 
applicable amount to be deducted from the pass-through payment, the 
''offset'' amount. We created an offset list comprised of any APC for 
which the device cost was at least 1 percent of the APC's cost.
    The offset list that we have published each year is a list of 
offset amounts associated with those APCs with identified offset 
amounts developed using the methodology described above. As a rule, we 
do not know in advance which procedures residing in certain APCs may be 
billed with new device categories. Therefore, an offset amount is 
applied only when a new device category is billed with a HCPCS 
procedure code that is assigned to an APC appearing on the offset list. 
The list of potential offsets for CY 2005 is currently published on the 
CMS Web site: http://www.cms.hhs.gov, as ``Device-Related Portions of 

Ambulatory Payment Classification Costs for 2005.''
    For CY 2004, we modified our policy for applying offsets to device 
pass-through payments. Specifically, we indicated that we would apply 
an offset to a new device category only when we could determine that an 
APC contains costs associated with the device. We continued our 
existing methodology for determining the offset amount, described 
earlier. We were able to use this methodology to establish the device 
offset amounts for CY 2004 because providers reported device codes (C-
codes) on the CY 2002 claims used for the CY 2004 OPPS update. For the 
CY 2005 update to the OPPS, our data consisted of CY 2003 claims that 
did not contain device codes and, therefore, for CY 2005 we utilized 
the device percentages as developed for CY 2004. In the CY 2004 OPPS 
update, we reviewed the device categories eligible

[[Page 42719]]

for continuing pass-through payment in CY 2004 to determine whether the 
costs associated with the device categories are packaged into the 
existing APCs. Based on our review of the data for the device 
categories existing in CY 2004, we determined that there were no close 
or identifiable costs associated with the devices relating to the 
respective APCs that are normally billed with them. Therefore, for 
those device categories, we set the offset to $0 for CY 2004. We 
continued this policy of setting offsets to $0 for the device 
categories that continued to receive pass-through payment in CY 2005.
    For the CY 2006 OPPS update, CY 2004 hospital claims are available 
for analysis. Hospitals billed device C-codes in CY 2004 on a voluntary 
basis. We have reviewed our CY 2004 data, examining hospital claims for 
services that included device C-codes and utilizing the methodology for 
calculating device offsets noted above. The numbers of claims for 
services in many of the APCs for which we calculated device percentages 
using CY 2004 data were quite small. Many of these APCs already had 
relatively few single claims available for median calculations compared 
with the total bill frequencies because of our inability to use many 
multiple bills in establishing median costs for all APCs, and 
subsetting the single claims to only those including C-codes often 
reduced those single bills by 80 percent or more. Our claims 
demonstrate that relatively few hospitals specifically coded for 
devices utilized in CY 2004. Thus, we do not feel confident that CY 
2004 claims reporting C-codes represent the typical costs of all 
hospitals providing the services. Therefore, we do not propose to use 
CY 2004 claims with device coding to propose CY 2006 device offset 
amounts at this time. In addition, we do not propose to use CY 2005's 
methodology, for which we utilized the device percentages as developed 
for CY 2004. Two years have passed since we developed the device 
offsets for CY 2004, and the device offsets originally calculated from 
CY 2002 hospitals' claims data may not appropriately reflect the 
contributions of device costs to procedural costs in the current 
outpatient hospital environment. In addition, a number of the APCs on 
the CY 2004 and CY 2005 device offset percentage lists are either no 
longer in existence or have been so significantly reconfigured that the 
past device offsets likely do not apply.
b. Proposed Policy for CY 2006
    For CY 2006, we are proposing to continue to review each new device 
category on a case-by-case basis as we have done in CY 2004 and CY 
2005, to determine whether device costs associated with the new 
category are packaged into the existing APC structure. If we do not 
determine that for any new device category that device costs associated 
with the new category are packaged into existing APCs, we are proposing 
to continue our current policy of setting the offset for the new 
category to $0 for CY 2006. There are currently no established 
categories that would continue for pass-through payment in CY 2006. 
However, we may establish new categories in any quarter. If we create a 
new device category and determine that our data contain a sufficient 
number of claims with identifiable costs associated with the devices in 
any APC, we would adjust the APC payment if the offset is greater than 
$0. If we determine that a device offset greater than $0 is appropriate 
for any new category that we create, we are proposing to announce the 
offset amounts in the program transmittal that announces the new 
category.
    For CY 2006, we are proposing to use available partial year or full 
year CY 2005 hospital claims data to calculate device percentages and 
potential offsets for CY 2006 applications for new device categories. 
Effective January 1, 2005, we require hospitals to report device C-
codes and their costs when hospitals bill for services which utilize 
devices described by the existing C-codes. In addition, during CY 2005 
we are implementing device edits for many services which require 
devices and for which appropriate device C-codes exist. Therefore, we 
expect that the number of claims including device codes and their 
respective costs will be much more robust and representative for CY 
2005 than for CY 2004. We also note that offsets would not be used for 
any existing categories at this time. If a new device category is 
created for payment, for CY 2006 we are proposing to examine the 
available CY 2005 claims data, including device costs, to determine 
whether device costs associated with the new category are already 
packaged into the existing APC structure, as indicated earlier. If we 
conclude that some related device costs are packaged into existing 
APCs, we are proposing to utilize the methodology described earlier and 
first used for the CY 2003 OPPS to determine an appropriate device 
offset percentage for those APCs with which the new category would be 
reported.
    Our proposal not to publish a list of APCs with device percentages 
at this time would be a transitional policy for CY 2006 because of the 
previously discussed limitations of the CY 2004 OPPS data with respect 
to device costs associated with procedures. We expect that we will 
reexamine our previous methodology for calculating the device 
percentages and offset amounts for the CY 2007 OPPS update, which will 
be based on CY 2005 hospitals claims data where device C-code reporting 
is required.
2. Criteria for Establishing New Pass-Through Device Categories
a. Surgical Insertion and Implantation Criterion
    One of our criteria, as set forth in Sec.  419.66(b)(3) of the 
regulations, for establishing a new category of devices for pass-
through payment is that the item be surgically inserted or implanted. 
The criterion that a device be surgically inserted or implanted is one 
of our original criteria adopted when we implemented the BBRA 
requirement that we establish pass-through payment for devices. This 
criterion helps us define whether an item is a device, as distinguished 
from other items, such as materials and supplies. We further clarified 
our definition of the surgical insertion and implantation criterion in 
the November 13, 2000 final rule (65 FR 67805). In that rule we stated 
that we consider a device to be surgically inserted or implanted if it 
is introduced into the human body through a surgically created 
incision. We also stated that we do not consider an item used to cut or 
otherwise create a surgical opening to be a device that is surgically 
inserted or implanted.
    In our November 15, 2004 final rule with comment period, we 
responded to comments received on our August 16, 2004 proposed rule, 
which requested that we revisit our surgical insertion and implantation 
criterion for establishing a new device category. The commenters 
specifically requested that CMS eliminate the current requirement that 
items that are included in new pass-through device categories must be 
surgically inserted or implanted through a surgically created incision. 
The commenters expressed concern that the current requirement may 
prevent access to innovative and less invasive technologies, 
particularly in the areas of gynecologic, urologic, colorectal and 
gastrointestinal procedures. These commenters asked that CMS change the 
surgical insertion or implantation criterion to allow pass-through 
payment for potential new device categories that include items 
introduced into the human body through a natural orifice, as well as 
through a surgically created incision. Several of the commenters

[[Page 42720]]

recommended that CMS allow the creation of a new pass-through category 
for items implanted or inserted through a natural orifice, as long as 
the other existing criteria are met.
    In responding to the commenters, we stated in the November 15, 2004 
final rule with comment period (69 FR 65774) that we were also 
interested in hearing the views of other parties and receiving 
additional information on these issues. While we appreciate and welcome 
additional comments on these issues from the medical device makers, we 
were also interested in hearing the views of Medicare beneficiaries, of 
the hospitals that are paid under the OPPS, and of physicians and other 
practitioners who attend to patients in the hospital outpatient 
setting. For that reason, we solicited additional comments on this 
topic within the 60-day comment period for the November 15, 2004 final 
rule with comment period (69 FR 65774 through 65775). In framing their 
comments, we asked that commenters consider the following questions 
specific to devices introduced into the body through natural orifices:
    1. Whether orifices include those that are either naturally or 
surgically created, as in the case of ostomies. If you believe this 
includes only natural orifices, why do you distinguish between natural 
and surgically created orifices?
    2. How would you define ``new,'' with respect to time and to 
predecessor technology? What additional criteria or characteristics do 
you believe distinguish ``new'' devices that are surgically introduced 
through an existing orifice from older technology that also is inserted 
through an orifice?
    3. What characteristics do you consider to distinguish a device 
that might be eligible for a pass-through category even if inserted 
through an existing orifice from materials and supplies such as 
sutures, clips or customized surgical kits that are used incident to a 
service or procedure?
    4. Are there differences with respect to instruments that are seen 
as supplies or equipment for open procedures when those same 
instruments are passed through an orifice using a scope?
b. Public Comments Received and Our Responses
    Below is a summary of the public comments we received on the four 
stated surgical insertion and implantation device criterion questions 
and our response to them.
    Comment: Most commenters generally framed their responses to the 
four questions listed above. Commenters were generally in favor of 
modifying our surgical insertion and implantation criterion so that 
devices that are placed into patients without the need for a surgical 
incision would not be ineligible for pass-through payment, claiming 
that devices that are inserted through a natural orifice offer 
important benefits to Medicare beneficiaries, such as avoidance of more 
costly and more invasive surgery. One commenter stated that procedures 
that could be performed with minimal morbidity and on an outpatient 
basis are the trend for surgery and should be encouraged. Another 
commenter believed that our criterion of surgical insertion or 
implantation through a surgically created incision was ineffective as a 
clear and comprehensive description of surgical procedures, including 
endoscopic and laparoscopic procedures.
    Regarding the first specific question we posed, whether devices 
introduced into the body through natural orifices includes orifices 
that are either naturally or surgically created, commenters generally 
stated we should include devices as potentially eligible for pass-
through categories whether they are introduced through orifices that 
are either naturally or surgically created, as in the case of ostomies, 
if the devices meet other cost and clinical criteria, in order to 
encourage the development of new technologies.
    Regarding the second question restated above, which asked how the 
public would define ``new'' with respect to time and to predecessor 
technology, some commenters stated that they believed the current 
clinical and cost criteria are sufficient and that no additional 
criteria or characteristics are needed. Several commenters indicated 
that the timeframe for what we consider ``new'' could be clarified if 
the device in question was not FDA approved or in use in the OPD during 
the year that hospital claims are used for that calendar year's OPPS 
update, that is, it should be considered ``new.'' Some commenters 
elaborated by example. They stated that if we change the surgical 
insertion or implantation requirement to include devices inserted 
through natural orifices in 2005, devices approved by the FDA and in 
use in the OPD in 2003 or previously would not be eligible, while 
devices approved by FDA in 2004 or later and used in the OPD settings 
would be eligible for pass-through consideration. Another commenter 
stated that the definition of ``new'' device should include those 
devices that require only an FDA investigational device exemption (IDE) 
clearance. The commenter further stated that these devices should be 
granted ``new'' status at the time of FDA release as an IDE. The 
commenter stated that if FDA required a premarket approval (PMA) for 
the device, a determination of newness should be made on a case by case 
basis.
    Regarding the question of what characteristics distinguish a device 
that might be eligible for a pass-through category even if inserted 
through an existing orifice from materials and supplies that are used 
incident to a service or procedure, some commenters generally stated 
their belief that the current clinical and cost criteria are sufficient 
to distinguish devices that might be eligible from materials and 
supplies. Other commenters stated that the device must be an integral 
part of the procedure or that it should include the characteristic of 
having a diagnostic or therapeutic purpose, without which the procedure 
could not be performed. Thus, according to these commenters, the device 
must function for a specific procedure, while supplies may be used for 
many procedures. One commenter pointed out that many devices are now 
implanted through the use of naturally occurring orifices or without 
significant incisions. This commenter indicated that the requirement of 
a ``traditional incision'' no longer serves the purpose of 
distinguishing between devices that are and are not implanted, or 
between devices and supplies and instruments. The commenter stated that 
retaining the requirement of a traditional incision could create 
incentives to use more invasive technology, if that is the technology 
that is eligible for pass-through payments and less invasive technology 
is not. This commenter suggested excluding tools and disposable 
supplies by excluding any item that is used primarily for the purpose 
of cutting or delivering an implantable device. However, the commenter 
recommended not reducing payment when delivery systems are packaged 
with the device. The commenter further recommended that the term 
incision be clearly defined to include all procedures involving the 
cutting, breaking or puncturing of tissue or skin, regardless of how 
small that cut is, provided that the device is attached to or inserted 
into the body via this cut or puncture or break. Another commenter 
stated that there are items included in a surgical kit that have 
significant cost and are single use, for example, guide wires, implying 
that it is sometimes difficult to determine what a supply is.
    Regarding our question about whether there are differences with 
respect to instruments that are seen as supplies or equipment for open 
procedures when those same instruments are passed through an orifice 
using a scope,

[[Page 42721]]

commenters believed that the definitions of supplies and eligible 
devices are independent of the use of a scope during a procedure, and 
stated there were no distinguishing features of supplies or equipment. 
A commenter reiterated that the current clinical and cost criteria are 
sufficient to distinguish eligible devices (that is, those with ``a 
specific therapeutic use'') from materials and supplies. Commenters 
believed that the use of a scope should not be a factor in the 
distinction between devices and supplies.
    One commenter urged us to consider the points that the surgical 
incision requirement is not mandated by statute and that CMS's 
criterion to limit devices to only those that are surgically inserted 
or implanted may have been based upon concern that less restrictive 
criteria would cause spending on pass-though items to exceed the pool 
of money set to fund the pass-though payments. This commenter indicated 
that this concern would no longer be valid, given the relatively few 
items currently paid on a pass-through basis.
    Response: As we stated in the November 15, 2004 final rule, we 
share the view that it is important to ensure access for Medicare 
beneficiaries to new technologies that offer substantial clinical 
improvement in the treatment of their medical conditions. We also 
recognize that since the beginning of the OPPS, there have been 
beneficial advances in technologies and services for many conditions, 
which have both markedly altered the courses of medical care and 
ultimately improved the health outcomes of many beneficiaries.
    We carefully considered the comments and are proposing to maintain 
our current criterion that a device must be surgically inserted or 
implanted, but are also proposing to modify the way we currently 
interpret this criterion under Sec.  419.66(b)(3) of the regulations. 
We are proposing to consider eligible those items that are surgically 
inserted or implanted either through a natural orifice or a surgically 
created orifice (such as through an ostomy), as well as those that are 
inserted or implanted through a surgically created incision. We will 
maintain all of our other criteria in Sec.  419.66 of the regulations, 
as elaborated in our various rules, such as the November 1, 2002 final 
rule (67 FR 66781 through 66787). Specifically, the clarification made 
at the time we clarified the surgically inserted or implanted criterion 
in our August 3, 2000 interim final rule with comment period, namely, 
that we do not consider an item used to cut or otherwise create a 
surgical opening to be a device that is surgically implanted or 
inserted (65 FR 67805).
    With this revision of our definition of devices that are surgically 
inserted or implanted, we remind the public that device category 
eligibility for transitional pass-through payment continues to depend 
on meeting our substantial clinical improvement criterion, where we 
compare the clinical outcomes of treatment options using the device to 
currently available treatments, including treatments using devices in 
existing or previously established pass-through device categories. We 
expect that requested new pass-through device categories that 
successfully demonstrate substantial clinical improvement for Medicare 
beneficiaries would describe new devices, where the additional device 
costs would not be reflected in the hospital claims data providing the 
costs of treatments available during the time period used for the most 
recent OPPS update.
c. Existing Device Category Criterion
    One of our criteria, as set forth in Sec.  419.66(c)(1) of the 
regulations, to establish a new device category for pass-through 
payment, is that the devices that would populate the category not be 
described by any existing or previously existing category. Commenters 
to our various proposed rules, as well as applicants for new device 
categories, have expressed concern that some of our existing and 
previously existing device category descriptors are overly broad, and 
that the category descriptors as they are currently written may 
preclude some new technologies from qualifying for establishment of a 
new device category for pass-through payment. Such parties have 
recommended that we consider modifying the descriptors for existing 
device categories, especially when a device would otherwise meet all 
the other criteria for establishing a new device category to qualify 
for pass-through payment.
    We agree that implementation of the requirement that a new device 
category not be described by an existing or previously existing 
category merits review. Beginning with CY 2006, 3 years will have 
elapsed since 95 of the 97 initial device categories we established on 
April 1, 2001 will have expired: 95 categories expired after December 
31, 2002, and 2 categories expired after December 31, 2003. Several 
additional years will have passed since those categories were first 
populated in CY 2000 or CY 2001. Thus, while some of the initial device 
category descriptors sufficed at the time they were first created, 
further clarification as to the types of devices that they are meant to 
describe is indicated. Therefore, we are proposing to create an 
additional category for devices that meet all of the criteria required 
to establish a new category for pass-through payment in instances where 
we believe that an existing or previously existing category descriptor 
does not appropriately describe the new type of device. This may entail 
the need to clarify or refine the short or long descriptors of the 
previous category. We would evaluate each situation on a case by case 
basis. We are proposing that any such clarification would be made 
prospectively from the date the new category would be made effective.
    We are also proposing to revise Sec.  419.66(c)(1) of the 
regulations, accordingly, to reflect as one of the criteria for 
establishing a device category our determination that a device is not 
appropriately described by any of the existing categories or by any 
category previously in effect. In order to determine if a ``new'' 
device is appropriately described by an existing or previously existing 
category of devices, we are proposing to apply two tests based upon our 
evaluation of information provided to us in the device category 
application. First, we will expect an applicant for a new device 
category to show that their device is not similar to devices (including 
related predicate devices) whose costs are reflected in our OPPS claims 
data in the most recent OPPS update. Second, we will require an 
applicant for a new device category to demonstrate that utilization of 
their device provides a substantial clinical improvement for Medicare 
beneficiaries compared with currently available treatments, including 
procedures utilizing devices in existing or previously existing device 
categories. We would consider a new device that meets both of these 
tests not to be appropriately described by one of the existing or 
previously existing pass-through device categories.

V. Proposed Payment Changes for Drugs, Biologicals, and 
Radiopharmaceutical Agents

A. Transitional Pass-Through Payment for Additional Costs of Drugs and 
Biologicals

(If you choose to comment on issues in this section, please include 
the caption ``Pass-Through'' at the beginning of your comment.)
1. Background
    Section 1833(t)(6) of the Act provides for temporary additional 
payments or ``transitional pass-through payments'' for certain drugs 
and biological agents. As originally enacted by the BBRA, this

[[Page 42722]]

provision required the Secretary to make additional payments to 
hospitals for current orphan drugs, as designated under section 526 of 
the Federal Food, Drug, and Cosmetic Act (Pub. L. 107-186); current 
drugs and biological agents and brachytherapy used for the treatment of 
cancer; and current radiopharmaceutical drugs and biological products. 
For those drugs and biological agents referred to as ``current,'' the 
transitional pass-through payment began on the first date the hospital 
OPPS was implemented (before enactment of BIPA (Pub. L. 106-554), on 
December 21, 2000).
    Transitional pass-through payments are also required for certain 
``new'' drugs, devices, and biological agents that were not being paid 
for as a hospital OPD service as of December 31, 1996, and whose cost 
is ``not insignificant'' in relation to the OPPS payment for the 
procedures or services associated with the new drug, device, or 
biological. Under the statute, transitional pass-through payments can 
be made for at least 2 years but not more than 3 years. In Addenda A 
and B to this proposed rule, pass-through drugs and biological agents 
are identified by status indicator ``G.''
    The process to apply for transitional pass-through payment for 
eligible drugs and biological agents can be found on our CMS Web site: 
http://www.cms.hhs.gov. If we revise the application instructions in 

any way, we will post the revisions on our Web site and submit the 
changes to the Office of Management and Budget (OMB) for approval, as 
required under the Paperwork Reduction Act (PRA). Notification of new 
drugs and biologicals application processes is generally posted on the 
OPPS Web site at: http://www.cms.hhs.gov/providers/hopps.

2. Expiration in CY 2005 of Pass-Through Status for Drugs and 
Biologicals
    Section 1833(t)(6)(C)(i) of the Act specifies that the duration of 
transitional pass-through payments for drugs and biologicals must be no 
less than 2 years and no longer than 3 years. The drugs whose pass-
through status will expire on December 31, 2005, meet that criterion. 
Table 19 below lists the 10 drugs and biologicals for which we are 
proposing that pass-through status would expire on December 31, 2005.

------------------------------------------------------------------------

3. Drugs and Biologicals With Proposed Pass-Through Status in CY 2006
    We are proposing to continue pass-through status in CY 2006 for 14 
drugs and biologicals. These items, which are listed in Table 20 below, 
were given pass-through status as of April 1, 2005. The APCs and HCPCS 
codes for drugs and biologicals that we are proposing to continue with 
pass-through status in CY 2006 are assigned status indicator ``G'' in 
Addendum A and Addendum B of this proposed rule.
    Section 1833(t)(6)(D)(i) of the Act sets the payment rate for pass-
through eligible drugs (assuming that no pro rata reduction in pass-
through payment is necessary) as the amount determined under section 
1842(o) of the Act. We note that this section of the Act also states 
that if a drug or biological is covered under a competitive acquisition 
contract under section 1847(B), then the payment rate be equal to the 
average price for the drug or biological for all competitive 
acquisition areas and year established as calculated and adjusted by 
the Secretary. The competitive acquisition program has not yet been 
implemented as of the development of this proposed rule; therefore, we 
do not have payment rates for certain drugs and biologicals that would 
be covered under this program at this time. Section 1847(A) of the Act, 
as added by section 303(c) of Pub. L. 108-173, establishes the use of 
the average sales price (ASP) methodology as the basis for payment of 
drugs and biologicals described in section 1842(o)(1)(C) of the Act and 
furnished on or after January 1, 2005. This payment methodology is set 
forth in Sec.  419.64 of the regulations. Similar to the payment policy 
established for pass-through drugs and biologicals in CY 2005, we are 
proposing to pay under the OPPS for drugs and biologicals with pass-
through status in CY 2006 consistent with the provisions of section 
1842(o) of the Act, as amended by section 621 of Pub. L. 108-173, at a 
rate that is equivalent to the payment these drugs and biologicals 
would receive in the physician office setting.
    Section 1833(t)(6)(D)(i) of the Act also sets the amount of 
additional payment for pass-through eligible drugs and biologicals (the 
pass-through payment amount). The pass-through payment amount is the 
difference between the amount authorized under section 1842(o) of the 
Act, and the portion of the otherwise applicable fee schedule amount 
(that is, the APC payment rate) that the Secretary determines is 
associated with the drug or biological.
    As we explain in section V.B. of this proposed rule, we are 
proposing to continue to make separate payment in CY 2006 for new drugs 
and biologicals with a HCPCS code consistent with the provisions of 
section 1842(o) of the Act, as amended by section 621 of Pub. L. 108-
173, at a rate that is equivalent to the payment they would receive in 
a physician office setting, whether or not we have received a pass-
through application for the item. Accordingly, in CY 2006, the pass-
through payment amount would equal zero for those new drugs and 
biologicals that we determine have pass-through status. That is, when 
we subtract the amount to be paid for pass-through drugs and 
biologicals under section 1842(o) of the Act, as amended by section 621 
of Pub. L. 108-173, from the portion of the otherwise applicable fee 
schedule amount, or the APC payment rate associated with the drug or 
biological that would be the amount paid for drugs and biologicals 
under section 1842(o) of the Act as amended by section 621 of Pub. L. 
108-173, the resulting difference is equal to zero.
    We are proposing to use payment rates based on the ASP data from 
the fourth quarter of 2004 for budget neutrality estimates, impact 
analyses, and to complete Addenda A and B of this proposed rule because 
these are the most recent numbers available to us during the 
development of this proposed rule. These payment rates were also the 
basis for drug payments in the physician office setting effective April 
1, 2005. To be consistent with the ASP-based payments that would be 
made when these drugs and biologicals are furnished in physician 
offices, we plan to make any appropriate adjustments to the amounts 
shown in Addenda A and B of this proposed rule when we publish our 
final rule and also on a quarterly basis on our Web site during CY 2006 
if later quarter ASP submissions indicate that adjustments to the 
payment rates for these pass-

    Table 20 lists the drugs and biologicals for which we are proposing

B. Proposed Payment for Drugs, Biologicals, and Radiopharmaceuticals 
Without Pass-Through Status

(If you choose to comment on issues in this section, please include 
the caption ``NonPass-Throughs'' at the beginning of your comment.)
1. Background
    Under the OPPS, we currently pay for drugs, biologicals including 
blood and blood products, and radiopharmaceuticals that do not have 
pass-through status in one of two ways: packaged payment and separate 
payment (individual APCs). We explained in the April 7, 2000 final rule 
(65 FR 18450) that we generally package the cost of drugs and 
radiopharmaceuticals into the APC payment rate for the procedure or 
treatment with which the products are usually furnished. Hospitals do 
not receive separate payment from Medicare for packaged items and 
supplies, and hospitals may not bill beneficiaries separately for any 
packaged items and supplies whose costs are recognized and paid for 
within the national OPPS payment rate for the associated procedure or 
service. (Program Memorandum Transmittal A-01-133, issued on November 
20, 2001, explains in greater detail the rules regarding separate 
payment for packaged services.)
    Packaging costs into a single aggregate payment for a service, 
procedure, or episode of care is a fundamental principle that 
distinguishes a prospective payment system from a fee schedule. In 
general, packaging the costs of items and services into the payment for 
the primary procedure or service with which they are associated 
encourages hospital efficiencies and also enables hospitals to manage 
their resources with maximum flexibility. Notwithstanding our 
commitment to package as many costs as possible, we are aware that 
packaging payments for certain drugs, biologicals, and 
radiopharmaceuticals, especially those that are particularly expensive 
or rarely used, might result in insufficient payments to hospitals, 
which could adversely affect beneficiary access to medically necessary 
services.
    Section 1833(t)(16)(B) of the Act, as added by section 621(a)(1) of 
Pub. L. 108-173, requires that the threshold for establishing separate 
APCs for drugs and biologicals be set at $50 per administration for CYs 
2005 and 2006. For CY 2005, we finalized our policy to continue paying 
separately for drugs, biologicals, and radiopharmaceuticals whose 
median cost per day exceeds $50 and packaging the cost of drugs, 
biologicals, and radiopharmaceuticals whose median cost per day is less 
than $50 into the procedures with which they are billed. For CY 2005, 
we also adopted an exception policy to our packaging rule for one 
particular class of drugs, the oral and injectible 5HT3 forms of anti-
emetic treatments (69 FR 65779 through 65780).
2. Proposed Criteria for Packaging Payment for Drugs, Biologicals, and 
Radiopharmaceuticals
    For CY 2006, the threshold for establishing separate APCs for drugs 
and biologicals is required to be set at $50 per administration 
according to section 1833(t)(16)(B) of the Act. Therefore, we are 
proposing to continue our existing policy of paying separately for 
drugs, biologicals, and radiopharmaceuticals whose per day cost exceeds 
$50 and packaging the cost of drugs, biologicals, and 
radiopharmaceuticals whose per day cost is less than $50 into the 
procedures with which they are billed. We are also proposing to 
continue our policy of exempting the oral and injectible 5HT3 anti-
emetic products from our packaging rule (Table 21), thereby making 
separate payment for all of the 5HT3 anti-emetic products. As stated in 
our CY 2005 final rule with comment period (69 FR 65779 through 65780), 
chemotherapy is very difficult for many patients to tolerate as the 
side effects are often debilitating. In order for beneficiaries to 
achieve the maximum therapeutic benefit from chemotherapy and other 
therapies with side effects of nausea and vomiting, anti-emetic use is 
often an integral part of the treatment regimen. We want to continue to 
ensure that our payment rules do not impede a beneficiary's access to 
the particular anti-emetic that is most effective for him or her as 
determined by the beneficiary and his or her physician.

------------------------------------------------------------------------

    For the CY 2006 proposed payment rates, we calculated the per day 
cost of all drugs, biologicals, and radiopharmaceuticals that had a 
HCPCS code in CY 2004 and were paid (via packaged or separate payment) 
under the OPPS using claims data from January 1, 2004, to December 31, 
2004. In CY 2004, multisource drugs and radiopharmaceuticals had two 
HCPCS codes that distinguished the innovator multisource (brand) drug 
or radiopharmaceutical from the noninnovator multisource (generic) drug 
or radiopharmaceutical. We aggregated claims for both the brand and 
generic HCPCS codes in our packaging analysis of these multisource 
products. Items such as single indication orphan drugs, certain 
vaccines, and blood and blood products were excluded from these 
calculations and our treatment of these items is discussed separately 
in sections V.F., E., and I., respectively, of this preamble.
    In order to calculate the per day cost for drugs, biologicals, and 
radiopharmaceuticals to determine their packaging status in CY 2006, we 
are proposing several changes in the methodology that was described in 
detail in the CY 2004 OPPS proposed rule (68 FR 47996 through 47997) 
and finalized in the CY 2004 final rule with comment period (68 FR 
63444 through 63447). For CY 2006, to calculate the per day cost of the 
drugs, biologicals, and radiopharmaceuticals, we took the following 
steps:

[[Page 42724]]

    Step 1. After application of the cost-to-charge ratios, we 
aggregated all line-items for a single date of service on a single 
claim for each product. This resulted in creation of a single line-item 
with the total number of units and the total cost of a drug or 
radiopharmaceutical given to a patient in a single day.
    Step 2. We then created a separate record for each drug or 
radiopharmaceutical by date of service, regardless of the number of 
lines on which the drug or radiopharmaceutical was billed on each 
claim. For example, ``drug X'' is billed on a claim with two different 
dates of service, and for each date of service, the drug is billed on 
two line-items with a cost of $10 and 5 units for each line-item. In 
this case, the computer program would create two records for this drug, 
and each record would have a total cost of $20 and 10 units of the 
product.
    Step 3. We trimmed records with unit counts per day greater or less 
than 3 standard deviations from the geometric mean (This is a new step 
in the methodology we are proposing for CY 2006).
    Step 4. For each remaining record for a drug or 
radiopharmaceutical, we calculated the cost per unit of the drug. If 
the HCPCS descriptor for ``drug X'' is ``per 1 mg'' and one record was 
created for a total of 10 mg (as indicated by the total number of units 
for the drug on the claim for each unique date of service), then the 
computer program divided the total cost for the record by 10 to give a 
per unit cost. We then weighted this unit cost by the total number of 
units in the record. We did this by generating a number of line-items 
equivalent to the number of units in that particular claim. Thus, a 
claim with 100 units of ``drug X'' and a total cost of $200 would be 
given 100 line-items, each with a cost of $2, while a claim of 50 units 
with a cost of $50 would be given 50 line items, each with a cost of 
$1.
    Step 5. We then trimmed the unit records with cost per unit greater 
or less than 3 standard deviations from the geometric mean.
    Step 6. We aggregated the remaining unit records to determine the 
mean cost per unit of the drug or radiopharmaceutical.
    Step 7. Using only the records that remained after records with 
unit counts per day greater or less than 3 standard deviations from the 
geometric mean were trimmed (step 3), the total number of units billed 
for each item and the total number of unique per-day records for each 
item were determined. We divided the count of the total number of units 
by the total number of unique per-day records for each item to 
calculate an average number of units per day.
    Step 8. Instead of using median cost as done in previous years, we 
used the payment rate for each drug and biological effective April 1, 
2005 furnished in the physician office setting, which was calculated 
using the ASP methodology, and multiplied the payment rate by the 
average number of units per day for each drug or biological to arrive 
at its per day cost. For items that did not have an ASP-based payment 
rate, we used their mean unit cost derived from the CY 2004 hospital 
claims data to determine their per day cost. Our reasoning for using 
these cost data is discussed in section V.B.3.a. of this preamble.
    Step 9. We then packaged the items with per day cost based on the 
ASP methodology or mean cost less than $50 and made items with per day 
cost greater than $50 separately payable.
    In the past, many commenters have alleged that hospitals do not 
accurately bill the number of units for drugs and radiopharmaceuticals. 
We have consistently decided not to identify which hospital claims 
contain correctly coded units because we do not believe we should be 
identifying when a dosage is clinically appropriate from hospital 
claims information. Variations among patients with respect to 
appropriate doses, the variety of indications with different dosing 
regimens for some agents, and the possibility of off-label uses make it 
difficult to know when units are incorrect. However, we do believe that 
trimming the units would improve the accuracy of estimates by removing 
those records with the most extreme units, without requiring us to 
speculate about clinically appropriate dosing. Therefore, we believe 
that trimming the records with unit counts greater or less than 3 
standard deviations from the geometric mean will eliminate claims from 
our analysis that may not appropriately represent the actual number of 
units of a drug or radiopharmaceutical furnished by a hospital to a 
patient during a specific clinical encounter. Because it reduces 
extreme variation, trimming on greater or less than 3 standard 
deviations from the geometric mean makes this trim more conservative 
and removes fewer records. This change in methodology gives us even 
greater confidence in the cost estimates we use for our packaging 
decisions. We are seeking comments on the changes that we are proposing 
in our methodology for packaging drugs and radiopharmaceuticals.
    Section 1833(t)(16)(B) of the Act that requires the threshold for 
establishing separate APCs for drugs and biologicals to be set at $50 
per administration will expire at the end of CY 2006. Therefore, we 
will be evaluating other packaging thresholds for these products for 
the CY 2007 OPPS update. We are specifically requesting comments on the 
use of alternative thresholds for packaging drugs and 
radiopharmaceuticals in CY 2007.
3. Proposed Payment for Drugs, Biologicals, and Radiopharmaceuticals 
Without Pass-Through Status That Are Not Packaged
a. Proposed Payment for Specified Covered Outpatient Drugs
(1) Background
    Section 1833(t)(14) of the Act, as added by section 621(a)(1) of 
Pub. L. 108-173, requires special classification of certain separately 
paid radiopharmaceutical agents, drugs, and biologicals and mandates 
specific payments for these items. Under section 1833(t)(14)(B)(i) of 
the Act, a ``specified covered outpatient drug'' is a covered 
outpatient drug, as defined in section 1927(k)(2) of the Act, for which 
a separate APC exists and that either is a radiopharmaceutical agent or 
is a drug or biological for which payment was made on a pass-through 
basis on or before December 31, 2002.
    Under section 1833(t)(14)(B)(ii) of the Act, certain drugs and 
biologicals are designated as exceptions and are not included in the 
definition of ``specified covered outpatient drugs.'' These exceptions 
are--
     A drug or biological for which payment is first made on or 
after January 1, 2003, under the transitional pass-through payment 
provision in section 1833(t)(6) of the Act.
     A drug or biological for which a temporary HCPCS code has 
not been assigned.
     During CYs 2004 and 2005, an orphan drug (as designated by 
the Secretary).
    Section 1833(t)(14)(F) of the Act defines the categories of drugs 
based on section 1861(t)(1) and sections 1927(k)(7)(A)(ii), 
(k)(7)(A)(iii), and (k)(7)(A)(iv) of the Act. The categories of drugs 
are ``sole source drugs (includes a biological product or a single 
source drug),'' ``innovator multiple source drugs,'' and ``noninnovator 
multiple source drugs.'' The definitions of these specified categories 
for drugs, biologicals, and radiopharmaceutical agents were discussed 
in the January 6, 2004 OPPS interim final rule with comment period (69 
FR 822), along with our use of the Medicaid average manufacturer price 
database to determine the appropriate classification

[[Page 42725]]

of these products. Because of the many comments received on the January 
6, 2004 interim final rule with comment period, the classification of 
many of the drugs, biologicals, and radiopharmaceuticals changed from 
that initially published. We announced these changes to the public on 
February 27, 2004, Transmittal 112, Change Request 3144. We also 
implemented additional classification changes through Transmittals 132 
(Change Request 3154, released March 30, 2004) and Transmittal 194 
(Change Request 3322, released June 4, 2004).
    Section 1833(t)(14)(A) of the Act, as added by section 621(a)(1) of 
Pub. L. 108-173, also provides that payment for these specified covered 
outpatient drugs for CYs 2004 and 2005 is to be based on its 
``reference average wholesale price.'' Section 1833(t)(14)(G) of the 
Act) defines reference AWP as the AWP determined under section 1842(o) 
of the Act as of May 1, 2003. Section 1833(t)(14)(A)(ii) of the Act, as 
added by section 621(a) of Pub. L. 108-173 requires that in CY 2005--
     A sole source drug must be paid no less than 83 percent 
and no more than 95 percent of the reference AWP.
     An innovator multiple source drug must be paid no more 
than 68 percent of the reference AWP.
     A noninnovator multiple source drug must be paid no more 
than 46 percent of the reference AWP.
    Section 1833(t)(14)(G) of the Act defines ``reference AWP'' as the 
AWP determined under section 1842(o) the Act as of May 1, 2003. We 
interpreted this to mean the AWP set under the CMS single drug pricer 
(SDP) based on prices published in the Red Book on May 1, 2003.
    For CY 2005, we finalized our policy to determine the payment rates 
for specified covered outpatient drugs under the provisions of Pub. L. 
108-173 by comparing the payment amount calculated under the median 
cost methodology as done for procedural APCs to the AWP percentages 
specified in section 1833(t)(14)(A)(ii) of the Act.
(2) Proposed Changes for CY 2006 Related to Pub. L. 108-173
    Section 1833(t)(14)(A)(iii) of the Act, as added by section 
621(a)(1) of Pub. L. 108-173, requires that payment for specified 
covered outpatient drugs in CY 2006 be equal to the average acquisition 
cost for the drug for that year as determined by the Secretary but 
subject to any adjustment for overhead costs and taking into account 
the hospital acquisition cost survey data collected by the GAO in 2004 
and 2005. If hospital acquisition cost data are not available, then the 
law requires that payment be equal to payment rates established under 
the methodology described in section 1842(o), section 1847(A), or 
section 1847(B) of the Act as calculated and adjusted by the Secretary 
as necessary.
(3) Data Sources Available for Setting CY 2006 Payment Rates
    Section 1833(t)(14)(D) of the Act, as added by section 621(a)(1) of 
Pub. L. 108-173, outlines the provisions of the hospital outpatient 
drug acquisition cost survey mandated for the GAO. This provision 
directs the GAO to collect data on hospital acquisition costs of 
specified covered outpatient drugs and to provide information based on 
these data that can be taken into consideration for setting CY 2006 
payment rates for these products under the OPPS. Accordingly, the GAO 
conducted a survey of 1,400 acute care, Medicare-certified hospitals 
requesting hospitals to provide purchase prices for specified covered 
outpatient drugs purchased from July 1, 2003 to June 30, 2004. The 
survey yielded a response rate of 83 percent where 1,157 hospitals 
provided usable information. To ensure that its methodology for data 
collection and analysis were sound, the GAO consulted an advisory panel 
of experts in pharmaceutical economics, pharmacy, medicine, survey 
sampling and Medicare payment.
    The GAO reported the average and median purchase prices for 55 
specified covered outpatient drug categories for the period July 1, 
2003 to June 30, 2004. These items represented 86 percent of the 
Medicare spending for specified covered outpatient drugs during the 
first 9 months of 2004. The initial GAO data did not include any 
radiopharmaceuticals. The report noted that the purchase price 
information accounted for volume and other discounts provided at the 
time of purchase, but excluded subsequent rebates from manufacturers 
and payments from group purchasing organizations.
    Another source of drug pricing information that we have is the ASP 
data from the fourth quarter of 2004, which were used to set payment 
rates for drugs and biologicals in the physician office setting 
effective April 1, 2005. We have ASP-based prices for approximately 475 
drugs and biologicals (including contrast agents) payable under the 
OPPS; however, we currently do not have any ASP data on 
radiopharmaceuticals. Payments for most of the drugs and biologicals 
paid in the physician office setting are based on the ASP+6 percent. 
Payments for items with no reported ASP are based on wholesale 
acquisition cost (WAC).
    Lastly, the third source of cost data we have for drugs, 
biologicals, and radiopharmaceuticals are the mean and median costs 
derived from the CY 2004 hospital claims data. In our data analysis, we 
compared the payment rates for drugs and biologicals using data from 
all three sources described above. As section 1833(t)(14)(A)(iii) of 
the Act clearly specifies that payment for specified covered outpatient 
drugs in CY 2006 be equal to the ``average'' acquisition cost for the 
drug, we limited our analysis to the mean costs of drugs determined 
using the GAO acquisition cost survey and the hospital claims data, 
instead of using median costs.
    We estimated aggregate expenditures for all drugs and biologicals 
(excluding radiopharmaceuticals) that would be separately payable in CY 
2006 and for the 55 drugs and biologicals reported by the GAO using 
mean cost from the claims data, the GAO mean purchase price, and the 
ASP-based payment amount (ASP+6 percent in most cases), and then 
calculated the equivalent average ASP-based payment rate under each of 
the three payment methodologies. The results are presented in Table 22 
below.

----------------------------------------------------------------------------------------------------------------

    Prior to any adjustments for the differing time periods of the 
pricing data, the results indicated that using the GAO mean purchase 
prices as the basis for paying the 55 drugs and biologicals would be 
equivalent to paying for those drugs and biologicals, on average, at 
ASP+3 percent. Additionally, using mean unit cost to set the payment 
rates for the drugs and biologicals that would be separately payable in 
CY 2006 would be equivalent to basing their payment rates, on average, 
at ASP+8 percent.
    In determining the payment rates for drugs and biologicals in CY 
2006, we are not proposing to use the GAO mean purchase prices for the 
55 drugs and biologicals because the GAO data reflect hospital 
acquisition costs from a less recent period of time. The survey was 
conducted from July 1, 2003 to June 30, 2004; thus, the purchase prices 
are generally reflective of the time that is the midpoint of this 
period, which is January 1, 2004. The hospital purchase price data also 
does not fully account for rebates from manufacturers or payments from 
group purchasing organizations made to hospitals. We also note that it 
would be difficult to update the GAO mean purchase prices during CY 
2006 and in future years.
    We are also not proposing, in general, to use mean costs from CY 
2004 hospital claims data to set payment rates for drugs and 
biologicals in CY 2006. In previous OPPS rules, we stated that pharmacy 
overhead costs are captured in the pharmacy revenue cost centers and 
reflected in the median cost of drug administration APCs, and the 
payment rate we established for a drug, biological, or 
radiopharmaceutical APC was intended to pay only for the cost of 
acquiring the item (66 FR 59896 and 67 FR 66769). However, findings 
from a MedPAC survey of hospital charging practices indicated that 
hospitals set charges for drugs, biologicals, and radiopharmaceuticals 
high enough to reflect their handling costs as well as their 
acquisition costs; therefore, the mean costs calculated using charges 
from hospital claims data converted to costs are representative of 
hospital acquisition costs for these products, as well as their 
overhead costs. For CY 2006, the statute specifies that payments for 
specified covered outpatient drugs are required to be equal to the 
``average'' acquisition cost for the drug. Payments based on mean costs 
would represent the products' acquisition costs plus overhead costs, 
instead of acquisition costs only. Therefore, we believe that it is 
appropriate for us to use a source of cost information other than the 
CY 2004 hospital claims data to set the payment rates for most drugs 
and biologicals in CY 2006.
    We are proposing to pay ASP+6 percent for separately payable drugs 
and biologicals in CY 2006. Given the data as described above, we 
believe this is our best estimate of average acquisition costs for CY 
2006. We note that the comparison between the GAO purchase price data 
and the ASP data indicated that the GAO data on average were equivalent 
to ASP+3 percent. However, as noted earlier, this comparison is 
problematic for two reasons. First, there are differences in the time 
periods for two sources of data. The GAO data are from the 12 months 
ending June 2004 and the ASP data are from the fourth quarter of 2004. 
It could be argued that prices increased in the intervening time 
period. However, we do not have a source of reliable information on 
specific price changes for this time period for the drugs studied by 
the GAO. In the future, we will have better information on price trends 
for Medicare Part B drugs as more quarters of pricing information are 
reported under the ASP system.
    We also note the comparison between the GAO data and the ASP data 
is problematic as the ASP data include rebates and other price 
concessions and the GAO data do not. Inclusion of these rebates and 
price concession in the GAO data would decrease the GAO prices relative 
to the ASP prices, suggesting that ASP+6 percent may be an overestimate 
of hospitals' average acquisition costs. Unfornately, we do not have a 
source of information on the magnitude of the rebates and price 
concessions for the specific drugs in the GAO data at this time.
    At the present time, therefore, it is difficult to adjust the GAO 
prices for inflation, rebates, and price concessions to make the 
comparison with ASP more precise. We will continue to examine new data 
to improve our future estimates of acquisition costs. In future years, 
our proposed pricing will be modified as appropriate to reflect the 
most recent data and analyses available. We also note that, in addition 
to the importance of making accurate estimates of acquisition costs for 
drug pricing, there are important implications for prices of other 
services due to the required budget neutrality of the OPPS. For 
example, drugs and biological prices set at ASP+3 percent instead of 
ASP+6 percent would have made available approximately an additional $60 
million for other items and services under the OPPS.
    We note that ASP data are unavailable for some drugs and 
biologicals. For the few drugs and biologicals, other than 
radiopharmaceuticals as discussed later, where ASP data are 
unavailable, we are proposing to use the mean costs from the CY 2004 
hospital claims data to determine their packaging status for 
ratesetting. Until we receive ASP data for these items, payment will be 
based on their mean cost.
    Our proposal uses payment rates based on ASP data from the fourth 
quarter of 2004 because these are the most recent numbers available to 
us during the development of this proposed rule. To be consistent with 
the ASP-based payments that would be made when these drugs and 
biologicals are furnished in physician offices, we plan to make any 
appropriate adjustments to the amounts shown in Addenda A and B to this 
proposed rule for these items based on more recent ASP data from the 
second quarter of 2005, which will be the basis for setting payment 
rates for drugs and biologicals in the physician office setting 
effective October 1, 2005, prior to our publication of the CY 2006 OPPS 
final rule and also on a quarterly basis on our Web site during CY 
2006. We note that we would determine the packaging status of each drug 
or biological only once during the year during the update process; 
however, for the separately payable drugs and biologicals, we would 
update their ASP-based payment rates on a quarterly basis.

[[Page 42727]]

    We intend for the quarterly updates of the ASP-based payment rates 
for separately payable drugs and biologicals to function as future 
surveys of hospital acquisition cost data, as section 
1833(t)(14)(D)(ii) of the Act instructs us to conduct periodic 
subsequent surveys to determine hospital acquisition cost for each 
specified covered outpatient drug.
    We are specifically requesting comments on our proposal to pay for 
drugs and biologicals (including contrast agents) under the OPPS using 
the ASP-based methodology that is also used to set the payment rates 
for drugs and biologicals furnished in physician offices and the 
adequacy of the payment rates to account for acquisition costs of the 
drugs and biologicals.
    In CY 2005, we applied an equitable adjustment to determine the 
payment rate for darbepoetin alfa (Q0137) pursuant to section 
1833(t)(2)(E) of the Act. However, for CY 2006, we are proposing to 
establish the payment rate for this biological using the ASP 
methodology. The ASP data represents market prices for this biological; 
therefore, we believe it is appropriate to use the ASP methodology to 
establish payment rates for darbepoetin alfa because this method will 
permit market forces to determine the appropriate payment for this 
biological. We are seeking comments on the proposed payment policy for 
this biological.
    Effective April 1, 2005, several HCPCS codes were created to 
describe various concentrations of low osmolar contrast material 
(LOCM). These new codes are Q9945 through Q9951. However, in 
Transmittal 514 (April 2005 Update of the OPPS), we instructed 
hospitals to continue reporting LOCM in CY 2005 using the existing 
HCPCS codes A4644, A4645, and A4646 and made Q9945 through Q9951 not 
payable under the OPPS. For CY 2006, we are proposing to activate the 
new Q-codes for hospitals and discontinue the use of HCPCS codes A4644 
through A4646 for billing LOCM products. We have CY 2004 hospital 
claims data for HCPCS codes A4644 through A4646, which show that the 
mean costs per day for these products are greater than $50. Because we 
do not have CY 2004 hospital claims data for HCPCS codes Q9945 through 
Q9951, we crosswalked the cost data for the HCPCS A-codes to the new Q-
codes. There is no predecessor code which crosswalks to HCPCS code 
Q9951 for LOCM with a concentration of 400 or greater mg/ml of iodine. 
Therefore, our general payment policy of paying separately for new 
codes while hospital data are being collected applies to HCPCS code 
Q9951. As our historical hospital mean per day costs for the three A 
codes exceed the packaging threshold and our payment policy for new 
codes without predecessors applies to one of the new codes, we are 
proposing to pay for the HCPCS codes Q9945 through Q9951 separately in 
CY 2006 at payment rates calculated using the ASP methodology. We note 
that because the new Q-codes describing LOCM are more descriptively 
discriminating and have different units than the previous A-codes for 
LOCM as well as widely varying ASPs, we expect that the packaging 
status of these Q-codes may change in future years when we have 
specific OPPS claims data for these new codes. We are seeking comments 
specifically on our proposed policy to pay separately for LOCM 
described by HCPCS codes Q9945 through Q9951 in CY 2006.
(4) CY 2006 Proposed Payment Policy for Radiopharmaceutical Agents
    We do not have ASP data for radiopharmaceuticals. Therefore, for CY 
2006, we are proposing to calculate per day costs of 
radiopharmaceuticals using mean unit cost from the CY 2004 hospital 
claims data to determine the items' packaging status similar to the 
drugs and biologicals with no ASP data. In a separate report, the GAO 
provided CMS with hospital purchase price information for nine 
radiopharmaceutical agents. As part of the GAO survey described 
earlier, the GAO surveyed 1,400 acute-care, Medicare-certified 
hospitals requesting hospitals to provide purchase prices for 
radiopharmaceuticals from July 1, 2003 to June 30, 2004. The 
radiopharmaceutical part of the survey yielded a response rate of 61 
percent, where 808 hospitals provided usable information. The GAO 
reported the average and median purchase prices for nine 
radiopharmaceuticals for the period July 1, 2003 to June 30, 2004. 
These items represented 9 percent of the Medicare spending for 
specified covered outpatient drugs during the first 9 months of 2004. 
The report noted that the purchase price information accounted for 
volume and other discounts provided at the time of purchase, but 
excluded subsequent rebates from manufacturers and payments from group 
purchasing organizations.
    When we examined differences between the CY 2005 payment rates for 
these nine radiopharmaceutical agents and their GAO mean purchase 
prices, we saw that the GAO purchase prices were substantially lower 
for several of these agents. We also saw similar patterns when we 
compared the CY 2005 payment rates for radiopharmaceutical agents with 
their CY 2004 median and mean costs from hospital claims data. Our 
intent is to maintain consistency, whenever possible between the 
payment rates for these agents from CY 2005 to CY 2006, because such 
rapid reductions could adversely affect beneficiary access to services 
utilizing radiopharmaceuticals.
    As we do not have ASPs for radiopharmaceuticals that best represent 
market prices, we are proposing as a temporary 1-year policy for CY 
2006 to pay for radiopharmaceutical agents that are separately payable 
in CY 2006 based on the hospital's charge for each radiopharmaceutical 
agent adjusted to cost. As MedPAC has indicated that hospitals 
currently include the charge for pharmacy overhead costs in their 
charge for the radiopharmaceutical, if we pay for these items using 
charges converted to cost, we believe that payment at cost would be the 
best available proxy for the average acquisition cost of the 
radiopharmaceutical along with its handling cost until we receive ASP 
information and overhead information on these agents. We expect that 
hospitals' different purchasing and preparation and handling practices 
for radiopharmaceuticals would be reflected in their charges, which 
would be converted to costs using hospital-specific cost-to-charge 
ratios. To better identify the separately payable radiopharmaceutical 
agents to which this policy would apply, we propose to assign them to 
status indicator ``H'' in Addendum B of this rule. Should ASP data be 
unavailable for radiopharmaceuticals for CY 2007, it is not apparent to 
us what methodology we could use to establish payment rates for these 
items in CY 2007 other than the hospital CY 2006 claims-based 
methodology. We are seeking comments specifically on the proposed 
payment policy for separately payable radiopharmaceutical agents in CY 
2006.
    Section 303(h) of Pub. L. 108-173 exempted radiopharmaceuticals 
from ASP pricing in the physician office setting where the fewer 
numbers (relative to the hospital outpatient setting) of 
radiopharmaceuticals are priced locally by Medicare contractors. 
However, radiopharmaceuticals are subject to ASP reporting. We 
currently do not require reporting for radiopharmaceuticals because we 
do not pay for any of the radiopharmaceuticals using the ASP 
methodology. However, for CY 2006, we are proposing to begin collecting 
ASP data on all radiopharmaceutical agents for purposes of ASP-based 
payment of

[[Page 42728]]

radiopharmaceuticals beginning in CY 2007.
    We recognize that there are significant complex issues surrounding 
the reporting of ASPs for radiopharmaceutical agents. Most 
radiopharmaceuticals must be compounded from a ``cold kit'' containing 
necessary nonradioactive materials for the final product to which a 
radioisotope is added. There are critical timing issues, given the 
short half-lives of many radioisotopes used for diagnostic or 
therapeutic purposes. Significant variations in practices exist with 
respect to what entity purchases the constituents and who then 
compounds the radiopharmaceutical to develop a final product for 
administration to a patient. For example, manufacturers may sell the 
components of a radiopharmaceutical to independent radiopharmacies. 
These radiopharmacies may then sell unit or multi-doses to many 
hospitals; however, some hospitals also may purchase the components of 
the radiopharmaceutical and prepare the radiopharmaceutical themselves. 
In some cases, hospitals may generate the radioisotope on-site, rather 
than purchasing it. The costs associated with acquiring the 
radiopharmaceutical in these instances may significantly vary. Also, 
there may only be manufacturer pricing for the components; however, the 
price set by the manufacturer for one component of a 
radiopharmaceutical may not directly translate into the acquisition 
cost of the ''complete'' radiopharmaceutical, which may result from the 
combination of several components. In general, for drugs other than 
radiopharmaceuticals, the products sold by manufacturers with National 
Drug Codes (NDCs) correspond directly with the HCPCS codes for the 
products administered to patients so ASPs may be directly calculated 
for the HCPCS codes. In the case of radiopharmaceuticals this 1:1 
relationship may not hold, potentially making the calculation of ASPs 
for radiopharmaceuticals more complex. In addition, some hospitals may 
generate their own radioisotopes, which they then use for 
radiopharmaceutical compounding, and they may sell these complete 
products to other sites. The costs associated with this practice could 
be difficult to capture through ASP reporting. We seek very specific 
comments on these and all other relevant issues surrounding 
implementation of ASP reporting for radiopharmaceuticals. We discuss in 
section V.B.3.a.(5) of this preamble under the MedPAC report on APC 
payment rate adjustments, our CY 2006 proposed payment policies for 
overhead costs of drugs, biologicals, and radiopharmaceuticals.
    In section V.D. of the preamble we discuss the methodology that we 
are proposing to use to determine the CY 2006 payment rates for new 
drugs, biologicals, and radiopharmaceuticals.
    While payments for drugs, biologicals and radiopharmaceuticals are 
taken into account when calculating budget neutrality, we note that we 
are proposing to pay for drugs, biologicals and radiopharmaceuticals 
without scaling these payment amounts. We believe that these payment 
amounts are the best proxies we have for the average acquisition costs 
of drugs, biologicals, and radiopharmaceuticals for CY 2006; therefore, 
Congress would not have intended for us to scale these payment rates. 
In section V.B.3.a.(5) of this preamble, we also discuss that we 
propose to add 2 percent of the ASP to the payment rates for drugs and 
biologicals with rates based on the ASP methodology to provide payment 
to hospitals for pharmacy overhead costs associated with furnishing 
these products. We are proposing to scale these additional payment 
amounts for pharmacy overhead costs. We are seeking comments on whether 
it is appropriate to exempt payment rates for drugs, biologicals, and 
radiopharmaceuticals from scaling and scale the additional payment 
amount for pharmacy overhead costs.
    We note that further discussion of the budget neutrality 
implications of the various drug payment proposals that we considered 
is included in section XIV.C. of this preamble.
(5) MedPAC Report on APC Payment Rate Adjustment of Specified Covered 
Outpatient Drugs
    Section 1833(t)(14)(E) of the Act, as added by section 621(a)(1) of 
Pub. L. 108-173, requires MedPAC to submit a report to the Secretary, 
not later than July 1, 2005, on adjusting the APC rates for specified 
covered outpatient drugs to take into account overhead and related 
expenses, such as pharmacy services and handling costs. This provision 
also requires that the MedPAC report include the following: A 
description and analysis of the data available for adjusting such 
overhead expenses; recommendation as to whether a payment adjustment 
should be made; and the methodology for adjusting payment, if an 
adjustment is recommended. Section 1833(t)(14)(E)(ii) of the Act, as 
added by section 621(a)(1) of Pub. L. 108-173, authorizes the Secretary 
to adjust the APC weights for specified covered outpatient drugs to 
reflect the MedPAC recommendation.
    The statute mandates MedPAC to report on whether drug APC payments 
under the OPPS should be adjusted to account for pharmacy overhead and 
nuclear medicine handling costs associated with providing specified 
covered outpatient drugs. In creating its framework for analysis, 
MedPAC interviewed stakeholders, analyzed cost report data, conducted 
four individual hospital case studies, and received technical advice on 
grouping items with similar handling costs from a team of experts in 
hospital pharmacy, hospital finance, cost accounting, and nuclear 
medicine.
    MedPAC concluded that the handling costs for drugs, biologicals, 
and radiopharmaceuticals delivered in the hospital outpatient 
department are not insignificant, as medications typically administered 
in outpatient departments generally require greater pharmacy 
preparation time than do those provided to inpatients. MedPAC found 
that little information is currently available about the magnitude of 
these costs. According to the MedPAC analysis, hospitals historically 
set charges for drugs, biologicals, and radiopharmaceuticals at levels 
that reflected their respective handling costs, and payments covered 
both drug acquisition and handling. Moreover, hospitals vary 
considerably in their likelihood of providing services which utilize 
drugs, biologicals, or radiopharmaceuticals with different handling 
costs.
    MedPAC developed seven drug categories for pharmacy and nuclear 
medicine handling costs, according to the level of resources used to 
prepare the products (Table 23). Characteristics associated with the 
level of handling resources required included radioactivity, toxicity, 
mode of administration, and the need for special handling. Groupings 
ranged from dispensing an oral medication on the low end of relative 
cost to providing radiopharmaceuticals on the high end. MedPAC 
collected cost data from four hospitals that were then used to develop 
relative median costs for all categories but radiopharmaceuticals 
(Category 7+). The case study facilities were not able to provide 
sufficient cost information regarding the handling of outpatient 
radiopharmaceuticals to develop a cost relative for Category 7+. The 
MedPAC study classified about 230 different drugs, biologicals, and 
radiopharmaceuticals into the seven categories based on input from 
their expert panel and each case study facility.

    In its report, MedPAC recommended the following:
    (1) Establish separate, budget neutral payments to cover the costs 
hospitals incur for handling separately payable drugs, biologicals, and 
radiopharmaceuticals; and
    (2) Define a set of handling fee APCs that group drugs, 
biologicals, and radiopharmaceuticals based on attributes of the 
products that affect handling costs; instruct hospitals to submit 
charges for these APCs; and base payment rates for the handling fee 
APCs on submitted charges reduced to costs.
    MedPAC found some differences in the categorizations of drug and 
radiopharmaceutical products by different experts and across the case 
study sites. In the majority of cases where groupings disagreed, 
hospitals used different forms of the products which were coded with 
the same HCPCS code. For example, a drug may be purchased as a 
prepackaged liquid or as a powder requiring reconstitution. Such a drug 
would vary in the handling resources required for its preparation and 
would fall into a different drug category depending on its form. In 
addition, the handling cost groupings may vary depending on the 
intended method of drug delivery, such as via intravenous push or 
intravenous infusion. For a number of commonly used drugs, MedPAC 
provided two categories in their final consensus categorizations, with 
the categories 2 and 3 reported as the most frequent combination. For 
example, MedPAC placed HCPCS codes J1260 (Injection, dolasetron 
mesylate, 10 mg) and J2020 (Injection, linezolid, 200 mg) in consensus 
categories 2 and 3, acknowledging that the appropriate categorization 
could vary depending on the clinical preparation and use of the drug. 
We note that we have no information regarding hospitals' frequencies of 
use of various forms of drugs provided in the outpatient department 
under the OPPS, as the case studies only included four facilities and 
the technical advisory committee was similarly small. Thus, in many 
cases it is impossible to exclusively and appropriately assign a drug 
to a certain overhead category that would apply to all hospital 
outpatient uses of the drug because of the different handling resources 
required to prepare different forms of the drugs.
    There are over 100 separately payable drugs, biologicals, and 
radiopharmaceuticals that are separately payable under the OPPS but for 
which MedPAC provided no consensus categorizations in its seven drug 
groups. We independently examined these products and considered the 
handling cost categories that could be appropriately assigned to each 
product as described by an individual HCPCS code. As discussed above, 
many of the drugs had several forms which would place them in different 
handling cost groupings depending on the specific form of the drug 
prepared by the hospital pharmacy for a patient's treatment. 
Additionally, we believe that hospitals may have difficulty 
discriminating among the seven categories for some drugs, because the 
applicability of a given category description to a specific clinical 
situation may be ambiguous. Indeed, in the MedPAC study, initially only 
about 80 percent of the case study pharmacists agreed with the expert 
panel category assignments; however, concurrence increased that 
percentage to almost 90 percent after discussion and review. 
Nevertheless, there remained a number of drugs for which differences in 
categorization by the case study facilities and the expert panel 
persisted.
    In light of our concerns over our ability to appropriately assign 
drugs to the seven MedPAC drug categories so that the categories 
accurately describe the drugs' attributes in all of the OPPS hospitals 
and the MedPAC recommendations, for CY 2006 we are proposing to 
establish three distinct HCPCS C-codes and three corresponding APCs for 
drug handling categories to differentiate overhead costs for drugs and 
biologicals, by combining several of the categories identified in the 
MedPAC report. We collapsed the MedPAC categories 2, 3, and 4 into a 
single category described by HCPCS code CXXXX, and MedPAC categories 5 
and 6 into another category described by HCPCS code CYYYY, while 
maintaining MedPAC category 1 as described by HCPCS code CWhttp://WWW. Our 

rationale for not creating an overhead payment category for 
radiopharmaceuticals is discussed below. We believe that merging 
categories in this way generally resolves the categorization dilemmas 
resulting from the most common scenarios where drugs may fall into more 
than one grouping and minimizes the administrative burden on hospitals 
to determine which category applies to the handling of a drug in a 
specific clinical situation. In addition, these broader handling cost 
groupings minimize any undesirable payment policy incentives to utilize 
particular forms of drugs or specific preparation methods. We have only 
collapsed those categories whose MedPAC relative weights differ by less 
than a factor of two, consistent with the principle outlined in section 
1833(t)(2) of the Act that provides that items and services within an 
APC group cannot be considered comparable with respect to the use of 
resources if the median of the highest cost item or service within an 
APC group is more than 2 times greater than the median of the lowest 
cost item or service within that same group.
    As noted previously, we believe that pharmacy overhead costs are 
captured in the pharmacy revenue cost centers and reflected in the 
median cost of drug

[[Page 42730]]

administration APCs, and the payment rate we established for a drug, 
biological, or radiopharmaceutical APC was intended to pay only for the 
cost of acquiring the item (66 FR 59896 and 67 FR 66769). As a MedPAC 
survey of hospital charging practices indicated that hospitals' charges 
for drugs, biologicals, and radiopharmaceuticals reflect their handling 
costs as well as their acquisition costs, we believe pharmacy overhead 
costs would be incorporated into the OPPS payment rates for drugs, 
biologicals, and radiopharmaceuticals if the rates are based on 
hospital claims data. However, in light of our proposal to establish 
three distinct C-codes for drug handling categories, we are proposing 
to instruct hospitals to charge the appropriate pharmacy overhead C-
code for overhead costs associated with each administration of each 
separately payable drug and biological based on the code description 
which best reflects the service the hospital provides to prepare the 
product for administration to a patient. We would then collect hospital 
charges for these C-codes for 2 years, and consider basing payment for 
the corresponding drug handling APCs on the charges reduced to costs in 
CY 2008, similar to the payment methodology for other procedural APCs. 
Median hospital costs for the drug handling APCs should reflect the CY 
2006 practice patterns across all OPPS hospitals of handling drugs 
whose preparation is described by each of the C-codes, reflecting the 
differential utilization of various forms of drugs and alternative 
methods of preparation and delivery through hospitals' billing and 
charges for the C-codes. Table 24 contains the drug handling 
categories, C-codes, and APCs we are proposing for CY 2006.

----------------------------------------------------------------------------------------------------------------

    We believe that these three categories are sufficiently distinct 
and reflective of the resources necessary for drug handling to permit 
appropriate hospital billing and to capture the varying overhead costs 
of the drugs and biologicals separately payable under the OPPS. We are 
not proposing to adopt the median cost relatives reported for MedPAC's 
six categories (excluding radiopharmaceuticals). It is very difficult 
to accurately crosswalk the cost relatives for the six categories to 
the three categories we are proposing. In addition, we are not 
confident that the cost relatives that were based on cost data from 
four hospitals appropriately reflect the median relative resource costs 
of all hospitals that would bill these drug handling services under the 
OPPS. Instead, we believe it is most appropriate to collect hospital 
charges for the drug handling services based on attributes of the 
products that affect the hospital resources required for their 
handling, and consider making future payments under the OPPS using the 
proposed C-codes based on the medians of charges converted to costs for 
the drug handling APC associated with each administration of a 
separately payable drug or biological.
    For CY 2006, pursuant to section 1833(t)(14)(E)(ii) of the Act, we 
propose an adjustment to cover the costs hospitals incur for handling 
separately payable drugs and biologicals. As we do not currently have 
separate hospital charge data on pharmacy overhead, we are proposing 
for CY 2006 to pay for drug and biological overhead costs based on 2 
percent of the ASP. As described earlier, we estimated aggregate 
expenditure for all separately payable OPPS drugs and biologicals 
(excluding radiopharmaceuticals) using mean costs from the claims data 
and then determined the equivalent average ASP-based rates. Our 
calculations indicated that using mean unit costs to set the payment 
rates for all separately payable drugs and biologicals would be 
equivalent to basing their payment rates on the ASP+8 percent. As noted 
previously, because pharmacy overhead costs are already built into the 
charges for drugs, biologicals, and radiopharmaceuticals as indicated 
by the MedPAC study described above, we believe that payment for drugs 
and biologicals and overhead at a combined ASP+8 percent would serve as 
a proxy for representing both the acquisition cost and overhead cost of 
each of these products. Moreover, as we are proposing to pay for all 
separately payable drugs and biologicals using the ASP methodology, 
where payment rates for most of these items are set at the ASP+6 
percent, we believe that an additional 2 percent of the ASP would 
provide adequate additional payment for the overhead cost of these 
products and be consistent with historical hospital costs for drug 
acquisition and handling. Even though we are not proposing to scale the 
payment rates for drugs and biologicals based on the ASP methodology, 
we are proposing to scale the additional payment amount of 2 percent of 
the ASP for pharmacy overhead costs. Therefore, for CY 2006, we are 
proposing to pay an additional 2 percent of the ASP scaled for budget 
neutrality for overhead costs associated with separately payable drugs 
and biologicals, along with paying ASP+6 percent for the acquisition 
costs of the drugs and biologicals. The payment rate for a separately 
payable drug or biological shown in Addenda A and B to this proposed 
rule represents the payment rate for the drug or biological in addition 
to payment for its overhead costs. We are specifically seeking comments 
on this proposed policy for paying for pharmacy overhead costs in CY 
2006 and on the proposed policy regarding hospital billing of drug 
handling charges associated with each administration of each separately 
payable drug or biological using the proposed C-codes.
    As discussed earlier, we are proposing to pay for separately 
payable radiopharmaceutical agents based on their charges in the claims 
submitted by hospitals converted to costs. MedPAC found that the 
handling resource costs

[[Page 42731]]

associated with radiopharmaceuticals were especially difficult to study 
because of the varying resource requirements for handling them in a 
variety of hospital outpatient settings for different clinical uses. 
These various methods of preparation of radiopharmaceuticals, and the 
individual radiopharmaceuticals themselves, differ significantly in the 
costs of their handling, with substantial variation in such factors as 
site of preparation, personnel time, shielding, transportation, 
equipment, waste disposal, and regulatory compliance requirements. 
However, as MedPAC also found that handling costs for drugs, 
biologicals, and radiopharmaceuticals were built into hospitals' 
charges for the products themselves, we believe that the charges from 
hospital claims converted to costs are representative of hospital 
acquisition costs for these agents, as well as their overhead costs. 
These costs would appropriately reflect each hospital's potentially 
diverse patterns of acquisition or production of radiopharmaceuticals 
for use in the outpatient hospital setting and their related handling 
costs that vary across radiopharmaceutical products and the 
circumstances of their production and use. Therefore, we are not 
proposing to create separate handling categories for 
radiopharmaceutical agents for CY 2006.
    However, because we are proposing to collect ASP information for 
radiopharmaceuticals in CY 2006, we are seeking specific comments on 
appropriate categories for potentially capturing radiopharmaceutical 
handling costs. We believe that these handling costs may vary depending 
on many factors. The handling cost categories should exclude any 
resources covered by specific diagnostic procedures or administration 
codes for patient services that utilize the radiopharmaceuticals. 
However, the handling cost categories should include all aspects of 
radiopharmaceutical handling and preparation, including transportation, 
storage, compounding, required shielding, inventory management, 
revision of dosages based on patient conditions, documentation, 
disposal, and regulatory compliance. The MedPAC study contractor 
suggested a variety of discriminating factors which may be related to 
the magnitude of radiopharmaceutical handling costs, including the 
complexity of the calculations and manipulations involved with 
compounding, the intended use of the product for diagnostic or 
therapeutic purposes, the item's status as a radioimmunoconjugate or 
non-radioimmunoconjugate, short-lived agents produced in-house, and 
preparation of the radiopharmaceutical in-house versus production in a 
commercial radiopharmacy. We are seeking comments on the construction 
of radiopharmaceutical handling cost categories that would meaningfully 
reflect differences in the levels of necessary hospital resources and 
that could easily be understood and applied by hospitals characterizing 
their preparation of radiopharmaceuticals.
b. Proposed CY 2006 Payment for Nonpass-Through Drugs, Biologicals, and 
Radiopharmaceuticals With HCPCS Codes, But Without OPPS Hospital Claims 
Data
    Pub. L. 108-173 does not address the OPPS payment in CY 2005 and 
after for new drugs, biologicals, and radiopharmaceuticals that have 
assigned HCPCS codes, but that do not have a reference AWP or approval 
for payment as pass-through drugs or biologicals. Because there is no 
statutory provision that dictated payment for such drugs and 
biologicals in CY 2005, and because we had no hospital claims data to 
use in establishing a payment rate for them, we investigated several 
payment options for CY 2005 and discussed them in detail in the CY 2005 
OPPS final rule with comment period (69 FR 65797 through 65799).
    For CY 2006, we are proposing to use the same methodology that we 
used in CY 2005. That is, we are proposing to pay for these new drugs 
and biologicals with HCPCS codes but which do not have pass-through 
status at a rate that is equivalent to the payment they would receive 
in the physician office setting, which would be established in 
accordance with the ASP methodology described in the CY 2005 Medicare 
Physician Fee Schedule final rule (69 FR 66299). As discussed in the 
OPPS CY 2005 final rule (69 FR 65797), new drugs, biologicals, and 
radiopharmaceuticals may be expensive and we are concerned that 
packaging these new items may jeopardize beneficiary access to them. In 
addition, we do not want to delay separate payment for these items 
solely because a pass-through application was not submitted. We note 
that this payment methodology is the same as the methodology that would 
be used to calculate the OPPS payment amount that pass-through drugs 
and biologicals would be paid in CY 2006 in accordance with section 
1842(o) of the Act, as amended by section 303(b) of Pub. L. 108-173, 
and section 1847A of the Act. Thus, we are proposing to continue to 
treat new drugs, biologicals, and radiopharmaceuticals with established 
HCPCS codes the same, irrespective of whether pass-through status has 
been determined. We are also proposing to assign status indicator ``K'' 
to HCPCS codes for new drugs and biologicals for which we have not 
received a pass-through application.
    There are several drugs, biologicals, and radiopharmaceuticals that 
were payable during CY 2004 or their HCPCS codes were created effective 
January 1, 2005 for which we do not have any CY 2004 hospital claims 
data. In order to determine the packaging status of these items for CY 
2006, we calculated an estimate of per day cost of each of these items 
by multiplying the payment rate for each product as determined using 
the ASP methodology by an estimated average number of units of each 
product that would be furnished to a patient during one administration. 
We are proposing to package items for which we estimated the per 
administration cost to be less than $50 and pay separately for items 
with estimated per administration cost greater than $50. Payment for 
the separately payable items would be based on rates determined using 
the ASP methodology established in the physician office setting. There 
are two codes 90393 (Vaccina ig, im) and Q9953 (Inj Fe-based MR 
contrast, ml) for which we were not able to determine payment rates 
based on the ASP methodology. Because we are unable to estimate the per 
administration cost of these items, we are proposing to package them in 
CY 2006. We are specifically seeking comments on our proposed policy 
for determining per administration cost of these drugs, biologicals, 
and radiopharmaceuticals that are payable under the OPPS, but do not 
have any CY 2004 claims data.

C. Proposed Coding and Billing Changes for Specified Covered Outpatient 
Drugs

(If you choose to comment on issues in this section, please include 
the caption ``Drug Coding and Billing'' at the beginning of your 
comment.)
1. Background
    As discussed in the January 6, 2004 interim final rule with comment 
period (69 FR 826), we instructed hospitals to bill for sole source 
drugs using the existing HCPCS codes, which were priced in accordance 
with the provisions of section 1833(t)(14)(A)(i) of the Act, as added 
by Pub. L. 108-173. However, at that time, the existing HCPCS codes did 
not allow us to differentiate payment amounts for innovator multiple 
source and noninnovator multiple source forms of the drug. Therefore, 
effective April 1, 2004, we implemented new HCPCS codes via Program 
Transmittal 112 (Change Request 3144, February 27, 2004) and Program 
Transmittal 132 (Change Request 3154, March 30, 2004) that providers 
were instructed to use to bill for innovator multiple source drugs in 
order to receive appropriate payment in accordance with section 
1833(t)(14)(A)(i)(II) of the Act. We also instructed providers to 
continue to use the existing HCPCS codes to bill for noninnovator 
multiple source drugs to receive payment in accordance with section 
1833(t)(14)(A)(i)(III) of the Act. These coding policies allowed 
hospitals to appropriately code for drugs, biologicals, and 
radiopharmaceuticals based on their classification and to be paid 
accordingly. We continued this coding practice in CY 2005 with payment 
made in accordance with section 1833(t)(14)(A)(ii) of the Act.
2. Proposed Policy for CY 2006
    For CY 2006, we are proposing to base the payment rates for drugs 
and biologicals and their pharmacy overhead costs on the ASP 
methodology that is used to set payment rates for these items in the 
physician office setting. Under this methodology, a single payment rate 
for the drug is calculated by considering the prices for both the 
innovator multiple source (brand) and noninnovator multiple source 
(generic) forms of the drug. Therefore, under the OPPS, we believe that 
there is no longer a need to differentiate between the brand and 
generic forms of a drug. Thus, we are proposing to discontinue use of 
the C-codes that were created to represent the innovator multiple 
source drugs. In CY 2006, hospitals would use the HCPCS codes for 
noninnovator multiple source (generic) drugs to bill for both the brand 
and generic forms of a drug as they did prior to implementation of 
section 1833(t)(14)(A) in Pub. L. 108-173. We are specifically 
requesting comments on this proposed policy.

D. Proposed Payment for New Drugs, Biologicals, and 
Radiopharmaceuticals Before HCPCS Codes Are Assigned

(If you choose to comment on issues in this section, please include 
the caption ``HCPCS Codes'' at the beginning of your comment.)
1. Background
    Historically, hospitals have used a HCPCS code for an unlisted or 
unclassified drug, biological, or radiopharmaceutical or used an 
appropriate revenue code to bill for drugs, biologicals, and 
radiopharmaceuticals furnished in the outpatient department that do not 
have an assigned HCPCS code. The codes for not otherwise classified 
drugs, biologicals, and radiopharmaceuticals are assigned packaged 
status under the OPPS. That is, separate payment is not made for the 
code, but charges for the code would be eligible for an outlier payment 
and, in future OPPS updates, the charges for the code are packaged with 
the separately payable service with which the code is reported for the 
same date of service.
    Drugs and biologicals that are newly approved by the FDA and for 
which a HCPCS code has not yet been assigned by the National HCPCS 
Alpha-Numeric Workgroup could qualify for pass-through payment under 
the OPPS. An application must be submitted to CMS in order for a drug 
or biological to be assigned pass-through status, a temporary C-code 
assigned for billing purposes, and an APC payment amount to be 
determined. Pass-through applications are reviewed on a flow basis, and 
payment for drugs and biologicals approved for pass-through status is 
implemented throughout the year as part of the quarterly updates of the 
OPPS.
2. Proposed Policy for CY 2006
    Section 1833(t)(15) of the Act, as added by section 621(a)(1) of 
Pub. L. 108-173, provides for payment for new drugs and biologicals 
until HCPCS codes are assigned under the OPPS. Under this provision, we 
are required to make payment for an outpatient drug or

[[Page 42733]]

biological that is furnished as part of the covered OPD services for 
which a HCPCS code has not been assigned in an amount equal to 95 
percent of AWP. This provision applies only to payments made under the 
OPPS on or after January 1, 2004.
    We initially adopted the methodology for determining payment under 
section 1833(t)(15) of the Act on an interim basis on May 28, 2004, via 
Transmittal 188, Change Request 3287, and finalized the methodology for 
CY 2005 in our CY 2005 OPPS final rule with comment period. In that 
final rule with comment period, we also expanded the methodology to 
include payment for new radiopharmaceuticals to which a HCPCS code is 
not assigned (69 FR 65804 through 65807). We instructed hospitals to 
bill for a drug or biological that is newly approved by the FDA by 
reporting the NDC for the product along with a new HCPCS code, C9399 
(Unclassified drug or biological). When HCPCS code C9399 appears on a 
claim, the OCE suspends the claim for manual pricing by the fiscal 
intermediary. The fiscal intermediary prices the claim at 95 percent of 
its AWP using the Red Book or an equivalent recognized compendium, and 
processes the claim for payment. This approach enables hospitals to 
bill and receive payment for a new drug, biological, or 
radiopharmaceutical concurrent with its approval by the FDA. The 
hospital does not have to wait for the next OPPS quarterly release or 
for approval of a product-specific HCPCS code to receive payment for a 
newly approved drug, biological, or radiopharmaceutical. In addition, 
the hospital does not have to resubmit claims for adjustment. Hospitals 
would discontinue billing HCPCS code C9399 and the NDC upon 
implementation of a HCPCS code, status indicator, and appropriate 
payment amount with the next OPPS quarterly update.
    For CY 2006, we are proposing to continue the same methodology for 
paying for new drugs, biologicals, and radiopharmaceuticals without 
HCPCS codes.

E. Proposed Payment for Vaccines

(If you choose to comment on issues in this section, please include 
the caption ``Vaccines'' at the beginning of your comment.)
    Outpatient hospital departments administer large numbers of 
immunizations for influenza (flu) and pneumococcal pneumonia (PPV), 
typically by participating in immunization programs. In recent years, 
the availability and cost of some vaccines (particularly the flu 
vaccine) have fluctuated considerably. As discussed in the November 1, 
2002 final rule (67 FR 66718), we were advised by providers that the 
OPPS payment was insufficient to cover the costs of the flu vaccine and 
that access of Medicare beneficiaries to flu vaccines might be limited. 
They cited the timing of updates to the OPPS rates as a major concern. 
They indicated that our update methodology, which uses 2-year-old 
claims data to recalibrate payment rates, would never be able to take 
into account yearly fluctuations in the costs of the flu vaccine. We 
agreed with this concern and decided to pay hospitals for influenza and 
pneumococcal pneumonia vaccines based on a reasonable cost methodology. 
As a result of this change, hospitals, home health agencies (HHAs), and 
hospices, which were paid for these vaccines under the OPPS in CY 2002, 
have been receiving payment at reasonable cost for these vaccines since 
CY 2003.
    Influenza, pneumococcal, and hepatitis B vaccines and their 
administration are specifically covered by Medicare under section 
1861(s)(10) of the Act. We are proposing to continue to pay influenza 
and pneumococcal vaccines at reasonable cost in CY 2006. However, 
hepatitis B vaccines so far have been paid under clinical APCs that 
also include other vaccines. For CY 2006, we are proposing to pay for 
all hepatitis B vaccines at reasonable cost, consistent with the 
payment methodology for influenza and pneumococcal vaccines. Influenza 
and pneumococcal vaccines are exempt from coinsurance and deductible 
payments under sections 1833(a)(3) and 1833(b) of the Act and have been 
assigned to status indicator ``L''. However, hepatitis B vaccines have 
no similar coinsurance or deductible exemption. Therefore, we are 
proposing to assign these items to status indicator ``F''.
    Previously, under the OPPS, separately payable vaccines other than 
influenza and pneumococcal were grouped into clinical APCs 355 and 356 
for payment purposes. Payment rates for these APCs were based on the 
APCs' median costs, calculated from the costs of all of the vaccines 
grouped within the APCs. For CY 2006, we are proposing to pay for each 
separately payable vaccine under its own APC, consistent with our 
policy for separately payable drugs other than vaccines, instead of 
aggregating them into clinical APCs with other vaccines. We believe 
this policy would allow us to more appropriately establish a payment 
rate for each separately payable vaccine based on the ASP methodology. 
We are specifically requesting comments on our proposed vaccine 
policies for CY 2006. Proposed policy changes to coding and payments 
for the administration of these vaccines are discussed in section VIII. 
of this preamble.

F. Proposed Changes in Payment for Single Indication Orphan Drugs

(If you choose to comment on issues in this section, please include 
the caption ``Orphan Drugs'' at the beginning of your comment.)

    Section 1833 (t)(1)((B)(i) of the Act gives the Secretary the 
authority to designate the hospital outpatient services to be covered. 
The Secretary has specified coverage for certain drugs as orphan drugs 
(section 1833(t)(14)(B)(ii)(III) of the Act, as added by section 
621(a)(1) of Pub. L. 108-173). Section 1833 (t)(14)(C) of the Act, as 
added by section 621(a)(1) of Pub. L. 108-173, gives the Secretary the 
authority in CYs 2004 and 2005 to specify the amount of payment for an 
orphan drug that has been designated as such by the Secretary.
    We recognize that orphan drugs that are used solely for an orphan 
condition or conditions are generally expensive and, by definition, are 
rarely used. We believe that if the costs of these drugs were packaged 
into the payment for an associated procedure or visit, the payment for 
the procedure might be insufficient to compensate a hospital for the 
typically high costs of this special type of drug. Therefore, we are 
proposing to continue paying for them separately.
    In the November 1, 2002 final rule (67 FR 66772), we identified 11 
single indication orphan drugs that are used solely for orphan 
conditions by applying the following criteria:
     The drug is designated as an orphan drug by the FDA and 
approved by the FDA for treatment of only one or more orphan 
condition(s).
     The current United States Pharmacopoeia Drug Information 
(USPDI) shows that the drug has neither an approved use nor an off-
label use for other than the orphan condition(s).
    Eleven single indication orphan drugs were identified as having met 
these criteria and payments for these drugs were made outside of the 
OPPS on a reasonable cost basis.
    In the November 7, 2003 final rule with comment period (68 FR 
63452), we discontinued payment for orphan drugs on a reasonable cost 
basis and made separate payments for each single indication orphan drug 
under its own APC. Payments for the orphan drugs were made at 88 
percent of the AWP listed for these drugs in the April 1, 2003 single 
drug pricer, unless we were presented with verifiable information

[[Page 42734]]

that showed that our payment rate did not reflect the price that was 
widely available to the hospital market. For CY 2004, Ceredase 
(alglucerase) and Cerezyme (imiglucerase) were paid at 94 percent of 
the AWP because external data submitted by commenters on the August 12, 
2003 proposed rule caused us to believe that payment at 88 percent of 
the AWP would be insufficient to ensure beneficiaries' access to these 
drugs.
    In the December 31, 2003 correction of the November 7, 2003 final 
rule with comment period (68 FR 75442), we added HCPCS code J9017 
(Arsenic trioxide, 1 mg) to our list of single indication orphan drugs. 
In the November 15, 2004 final rule with comment period (69 FR 65807), 
we retained the same criteria for identifying single indication orphan 
drugs and added two HCPCS codes to our list--C9218 (Injection, 
Azactidine, per 1 mg) and J9010 (Alemtuzumab, 10 mg) (69 FR 65808). As 
of CY 2005, the following are the 14 orphan drugs that we have 
identified as meeting our criteria: C9218 (Injection, Azactidine, per 1 
mg); J0205 (Injection, Alglucerase, per 10 units); J0256 (Injection, 
Alpha 1-proteinase inhibitor, 10 mg); J9300 (Gemtuzumab ozogamicin, 
5mg); J1785 (Injection, Imiglucerase, per unit); J2355 (Injection, 
Oprelvekin, 5 mg); J3240 (Injection, Thyrotropin alpha, 0.9 mg); J7513 
(Daclizumab, parenteral, 25 mg); J9010 (Alemtuzumab, 10 mg); J9015 
(Aldesleukin, per single use vial); J9017 (Arsenic trioxide, 1 mg); 
J9160 (Denileukin diftitox, 300 mcg); J9216 (Interferon, gamma 1-b, 3 
million units); and Q2019 (Injection, Basiliximab, 20 mg).
    In the November 15, 2004 final rule with comment period (69 FR 
65808), we stated that had we not classified these drugs as single 
indication orphan drugs for payment under the OPPS, they would have met 
the definition of single source specified covered outpatient drugs and 
received lower payments, which could have impeded beneficiary access to 
these unique drugs dedicated to the treatment of rare diseases. 
Instead, for CY 2005, under our authority at section 1833(t)(14)(C) of 
the Act, we set payment for all 14 single indication orphan drugs at 
the higher of 88 percent of the AWP or the ASP+6 percent. For CY 2005, 
we also updated on a quarterly basis the payment rates through 
comparison of the most current ASP and AWP information available to us. 
Given that CY 2005 was the first year of mandatory ASP reporting by 
manufacturers, we did not want potential significant fluctuations in 
the ASPs to affect payments to hospitals furnishing these drugs, which 
in turn might cause access problems for beneficiaries. Therefore, in 
the November 15, 2004 final rule, we did not implement the proposed 95 
percent AWP cap on payments for single indication orphan drugs which 
was described in the August 16, 2004 proposed rule (69 FR 50518), as we 
intended to monitor the impact of our payment policy and consider the 
need for a cap in future OPPS updates if appropriate (69 FR 65809).
    As a part of the GAO study on hospital acquisition costs of 
specified covered outpatient drugs, the GAO provided the average 
hospital purchase prices for four orphan drugs: J0256 (Injection, Alpha 
1-proteinase inhibitor, 10 mg), J1785 (Injection, Imiglucerase, per 
unit), J9160 (Denileukin difitox, 300 mcg), and J9010 (Alemtuzumab, 10 
mg).
    For alpha 1-proteinase inhibitor (J0256), the hospitals in the 
study sample represented only about 14 percent of the estimated total 
number of hospitals purchasing the drug. The mean hospital purchase 
price was about 73 percent of the payment rate based on ASP+6 percent 
rate and about 63 percent of the CY 2005 payment rate updated in April 
2005. We believe the GAO acquisition data for alpha 1-proteinase 
inhibitor are likely not representative of hospital acquisition costs 
for the drug because the number of hospitals providing data was so 
small compared to the total number of hospitals expected to utilize the 
drug. Furthermore, we recognize that the GAO data on hospital drug 
acquisition costs do not reflect the current acquisition costs 
experienced by hospitals but instead, rely on past cost data from late 
CY 2003 through early CY 2004. On the other hand, the ASP data are more 
current and thus are likely more reflective of present hospital 
acquisition costs for alpha 1-proteinase inhibitor.
    In contrast to the GAO data for alpha 1-proteinase inhibitor, the 
GAO data for imiglucerase (J1785) reflect hospital purchase prices from 
about 69 percent of the hospitals expected to utilize the drug. For 
this drug, the mean hospital purchase price was about 93 percent of the 
CY 2005 payment rate for imiglucerase updated in April 2005, which was 
based on ASP+6 percent rate. Thus, the ASP-based payment rate also 
would appear to be appropriately reflective of hospital acquisition 
costs for imiglucerase, and to be consistent with the GAO mean purchase 
price.
    For denileukin difitox (J9160) and alemtuzumab (J9010), the GAO 
data for these drugs reflect hospital purchase prices from about 77 
percent and 66 percent of the hospitals expected to acquire these 
drugs, respectively. The mean hospital purchase price for denileukin 
difitox was about 94 percent of the payment rate based on the ASP+6 
percent rate and about 79 percent of the CY 2005 payment rate. As for 
alemtuzumab, the mean hospital purchase price was about 95 percent of 
the payment rate based on the ASP+6 percent rate and about 89 percent 
of the CY 2005 payment rate. For both of these drugs, the ASP-based 
payment rates also appear to be appropriately reflective of their 
hospital acquisition costs, based on confirmation by the GAO average 
purchase price data from over two-thirds of the hospitals expected to 
acquire the drugs.
    During the quarterly updates to payment rates for single indication 
orphan drugs for CY 2005, we observed significant improvement in the 
accuracy and consistency of manufacturers' reporting of the ASPs for 
these orphan drugs. Overall, we found that the ASPs as compared to the 
AWPs were less likely to experience dramatic fluctuations in prices 
from quarter to quarter. We expect that as the ASP system continues to 
mature, manufacturers will further refine their quarterly reporting, 
leading to even greater stability and accuracy in their reporting of 
sales prices. As the ASPs reflect the average sales prices to all 
purchasers, the ASP data also include drug sales to hospitals. Past 
commenters have indicated to us that some orphan drugs are administered 
principally in hospitals, and to the extent that this is true their 
ASPs should predominantly be based upon the sales of drugs used by 
hospitals. For three of the orphan drugs for which the GAO provided 
average purchase prices from a large percentage of hospitals expected 
to acquire the drugs, the GAO data were very consistent with the ASP+6 
percent. For the fourth drug, the GAO mean was significantly lower than 
the ASP+6 percent and the confidence interval around that mean was 
quite tight, although only a small proportion of hospitals expected to 
acquire the drug reported their purchase prices. Thus, we believe that 
proposing to pay for orphan drugs based on an ASP methodology is 
appropriate for the CY 2006 OPPS and should assure patients' continued 
access to these orphan drugs in the hospital outpatient department. 
Therefore, for CY 2006, we are proposing to pay for single indication 
orphan drugs at the ASP+6 percent. We believe that paying for orphan 
drugs using the ASP methodology is consistent with our proposed general 
drug payment policy for other separately payable drugs and

[[Page 42735]]

biologicals in the CY 2006 and reflects our general view that ASP-based 
payment rates serve as the best proxy for the average acquisition cost 
for these items as described in this section V. of the preamble. In 
addition, we are proposing to pay an additional 2 percent of the ASP 
scaled for budget neutrality to cover the handling costs of these 
drugs, also consistent with our proposed general pharmacy overhead 
payment policy for handling costs associated with separately payable 
drugs and biologicals. We believe that the ASPs plus 6 percent for 
orphan drugs will provide appropriate payment for hospital acquisition 
costs for these drugs that are administered by a relatively small 
number of providers, so that patients will continue to have access to 
orphan drugs in the hospital outpatient setting. Hospitals will also 
receive additional payments for costs associated with their storage, 
handling, and preparation of orphan drugs. Payment rates will be 
updated on a quarterly basis to reflect the most current ASPs available 
to us. Appropriate adjustments to the payment amounts shown in Addendum 
A and B would be made if the ASP submissions in a later quarter 
indicate that adjustments to the payment rates are necessary. These 
changes to the Addenda would be announced in our program instructions 
released on a quarterly basis and posted on our Web site at http://www.cms.hhs.gov.
 We are specifically requesting comments on our 

proposed payment policy for orphan drugs in CY 2006.

VI. Estimate of Transitional Pass-Through Spending in CY 2006 for 
Drugs, Biologicals, and Devices

(If you choose to comment on issues in this section, please include 
the caption ``Estimated Transitional Pass-Through Spending'' at the 
beginning of your comment.)

A. Total Allowed Pass-Through Spending

    Section 1833(t)(6)(E) of the Act limits the total projected amount 
of transitional pass-through payments for drugs, biologicals, 
radiopharmaceuticals, and categories of devices for a given year to an 
``applicable percentage'' of projected total Medicare and beneficiary 
payments under the hospital OPPS. For a year before CY 2004, the 
applicable percentage was 2.5 percent; for CY 2005 and subsequent 
years, we specify the applicable percentage up to 2.0 percent.
    If we estimate before the beginning of the calendar year that the 
total amount of pass-through payments in that year would exceed the 
applicable percentage, section 1833(t)(6)(E)(iii) of the Act requires a 
uniform reduction in the amount of each of the transitional pass-
through payments made in that year to ensure that the limit is not 
exceeded. We make an estimate of pass-through spending to determine not 
only whether payments exceed the applicable percentage, but also to 
determine the appropriate reduction to the conversion factor for the 
projected level of pass-through spending in the following year.
    For devices, making an estimate of pass-through spending in CY 2006 
entails estimating spending for two groups of items. The first group 
consists of those items for which we have claims data for procedures 
that we believe used devices that were eligible for pass-through status 
in CY 2004 and CY 2005 and that would continue to be eligible for pass-
through payment in CY 2006. The second group consists of those items 
for which we have no direct claims data, that is, items that became, or 
would become, eligible in CY 2005 and would retain pass-through status 
in CY 2006, as well as items that would be newly eligible for pass-
through payment beginning in CY 2006.

B. Estimate of Pass-Through Spending for CY 2006

    We are proposing to set the applicable percentage cap at 2.0 
percent of the total OPPS projected payments for CY 2006. As we discuss 
in section IV.C. of this preamble, the three remaining device 
categories receiving pass-through payment in CY 2005 will expire on 
December 31, 2005. Therefore, we estimate pass-through spending 
attributable to the first group of items described above to equal zero.
    To estimate CY 2006 pass-through spending for device categories in 
the second group, that is, items for which we have no direct claims 
data, we are proposing to use the following approach: For additional 
device categories that are approved for pass-through status after July 
1, 2005, but before January 1, 2006, we are proposing to use price 
information from manufacturers and volume estimates based on claims for 
procedures that would most likely use the devices in question because 
we would have no CY 2004 claims data upon which to base a spending 
estimate. We are proposing to project these data forward to CY 2006 
using inflation and utilization factors based on total growth in OPPS 
services as projected by CMS' Office of the Actuary (OACT) to estimate 
CY 2006 pass-through spending for this group of device categories. For 
device categories that become eligible for pass-through status in CY 
2006, we are proposing to use the same methodology. We anticipate that 
any new categories for January 1, 2006, would be announced after the 
publication of this proposed rule, but before publication of the final 
rule. Therefore, the estimate of pass-through spending in the CY 2006 
OPPS final rule would incorporate any pass-through spending for device 
categories made effective January 1, 2006, and during subsequent 
quarters of CY 2006.
    With respect to CY 2006 pass-through spending for drugs and 
biologicals, as we explain in section V.A.3. of this proposed rule, the 
pass-through payment amount for new drugs and biologicals that we 
determine have pass-through status would equal zero. Therefore, our 
estimate of pass-through spending for drugs and biologicals with pass-
through status in CY 2006 equals zero.
    In accordance with the methodology described above and the 
methodology for estimating pass-through spending discussed in the 
August 16, 2004 proposed rule (69 FR 50526), we estimate that total 
pass-through spending for device categories that first become eligible 
for pass-through status after publication of this proposed rule for 
which pass-through payment continues in CY 2006 or become eligible 
during CY 2006 would equal approximately $12.5 million, which 
represents 0.05 percent of total OPPS projected payments for CY 2006. 
This figure includes estimates for the current device categories 
continuing into CY 2006, which equals zero, in addition to projections 
for categories that first become eligible during the second half of CY 
2005 or in CY 2006.
    This estimate of total pass-through spending for CY 2006 is 
significantly lower than previous years' estimates both because of the 
method we are proposing in section V.A.3. of this preamble for 
determining the amount of pass-through payment for drugs and 
biologicals with pass-through status, and the fact that there are no CY 
2005 pass-through device categories that are being carried over to CY 
2006.
    Because we estimate pass-through spending in CY 2006 would not 
amount to 2.0 percent of total projected OPPS CY 2006 spending, we are 
proposing to return 1.95 percent of the pass-through pool to adjust the 
conversion factor, as we discuss in section II.C. of this preamble.

VII. Proposed Brachytherapy Payment Changes

(If you choose to comment on issues in this section, please include 
the caption ``Brachytherapy'' at the beginning of your comment.)

A. Background

    Section 1833(t)(16)(C) and section 1833(t)(2)(H) of the Act, as 
added by sections 621(b)(1) and (b)(2) of Pub. L. 108-173, 
respectively, establish separate payment for devices of brachytherapy 
consisting of a seed or seeds (or radioactive source) based on a 
hospital's charges for the service, adjusted to cost. Charges for the 
brachytherapy devices may not be used in determining any outlier 
payments under the OPPS. In addition, consistent with our practice 
under the OPPS to exclude items paid at cost from budget neutrality 
consideration, these items must be excluded from budget neutrality as 
well. The period of payment under this provision is for brachytherapy 
sources furnished from January 1, 2004, through December 31, 2006.
    Section 621(b)(3) of Pub. L. 108-173 requires the Government 
Accountability Office (GAO) to conduct a study to determine appropriate 
payment amounts for devices of brachytherapy, and to submit a report on 
its study to the Congress and the Secretary, including recommendations. 
We are awaiting the report and any recommendations on the payment of 
brachytherapy, which would pertain to brachytherapy payments after 
December 31, 2006.
    In the OPPS interim final rule with comment period published on 
January 6, 2004 (69 FR 827), we implemented sections 621(b)(1) and 
(b)(2)(C) of Pub. L. 108-173. In that rule, we stated that we will pay 
for the brachytherapy sources listed in Table 4 of the interim final 
rule with comment period (69 FR 828) on a cost basis, as required by 
the statute. The status indicator for brachytherapy sources was changed 
to ``H.'' The definition of status indicator ``H'' was for pass-through 
payment only for devices, but the brachytherapy sources affected by 
sections 1833(t)(16)(C) and 1833(t)(2)(H) of the Act are not pass-
through device categories. Therefore, we also changed, for CY 2004, the 
definition of payment status indicator ``H'' to include nonpass-through 
brachytherapy sources paid on a cost basis. This use of status 
indicator ``H'' was a pragmatic decision that allowed us to pay for 
brachytherapy sources in accordance with section 1833(t)(16)(C) of the 
Act, effective January 1, 2004, without having to modify our claims 
processing systems. We stated in the January 6, 2004 interim final rule 
with comment period that we would revisit the use and definition of 
status indicator ``H'' for this purpose in the OPPS update for CY 2005. 
In the November 15, 2004 final rule with comment period, we finalized 
this policy for CY 2005 (69 FR 65838).
    As we indicated in the January 6, 2004 interim final rule with 
comment period, we began payment for the brachytherapy source in HCPCS 
code C1717 (Brachytx source, HCR lr-192) based on the hospital's charge 
adjusted to cost beginning January 1, 2004. Prior to enactment of Pub. 
L. 108-173, these sources were paid as packaged services in APC 0313. 
As a result of the requirement under Pub. L. 108-173 to pay for HCPCS 
code C1717 separately, we adjusted the payment rate for APC 0313, 
Brachytherapy, to reflect the unpackaging of the brachytherapy source. 
We finalized this payment methodology in our November 15, 2004 final 
rule with comment period (69 FR 65839).
    Section 1833(t)(2)(H) of the Act, as added by section 621(b)(2)(C) 
of Pub. L. 108-173, mandated the creation of separate groups of covered 
OPD services that classify brachytherapy devices separately from other 
services or groups of services. The additional groups must be created 
in a manner that reflects the number, isotope, and radioactive 
intensity of the devices of brachytherapy furnished, including separate 
groups for Palladium-103 and Iodine-125 devices. At its meetings in 
February 2004, the APC Panel heard from parties that recommended the 
addition of two new codes to describe brachtherapy sources in a manner 
that reflects the number, radioisostope, and radioactive intensity of 
the sources. The presenters recommended two new brachytherapy HCPCS 
codes and APCs for high activity Iodine-125 and high activity 
Palladium-103. The APC Panel, in turn, recommended that CMS establish 
new HCPCS codes and new APCs, on a per source basis, for these two 
brachytherapy sources.
    We considered this recommendation and agreed with the APC Panel. 
Therefore, in the November 15, 2004 final rule with comment period, we 
established the following two new brachytherapy source codes for CY 
2005:
    C2634 Brachytherapy source, High Activity Iodine-125, greater than 
1.01 mCi (NIST), per source
    C2635 Brachytherapy source, High Activity Palladium-103, greater 
than 2.2 mCi (NIST), per source
    In addition, we believed the APC Panel's recommendation to 
establish new HCPCS codes that would distinguish high activity Iodine-
125 from high activity Palladium-103 on a per source basis should have 
been implemented for other brachytherapy code descriptors, as well. 
Therefore, beginning January 1, 2005, we included ``per source'' in the 
HCPCS code descriptors for all those brachytherapy source descriptors 
for which units of payment were not already delineated. Table 40 
published in the November 15, 2004 final rule with comment period 
included a complete listing of the HCPCS codes, long descriptors, APC 
assignments, and status indicators that we used for brachytherapy 
sources paid under the OPPS in CY 2005 (69 FR 65840 through 65841).
    Further, for CY 2005, we added the following code of linear source 
Palladium-103 to be paid at cost: C2636 Brachytherapy linear source, 
Palladium-103, per 1 mm. We had indicated in our August 16, 2004 
proposed rule that we were aware of a new linear source Palladium-103, 
which came to our attention in CY 2003 through an application for a new 
device category for pass-through payment. We stated that, while we 
decided not to create a new category for pass-through payment, we 
believed that the new linear source fell under the provisions of Pub. 
L. 108-173. Therefore, we made final our proposal to add HCPCS code 
C2636 as a new brachytherapy source to be paid at cost in CY 2005.

B. Proposed Changes Related to Pub. L. 108-173

    We have consistently invited the public to submit recommendations 
for new codes to describe brachytherapy sources in a manner reflecting 
the number, radioisotope, and radioactivity intensity of the sources. 
We requested that commenters provide a detailed rationale to support 
recommended new codes and to send recommendations to us. We stated that 
we would endeavor to add new brachytherapy source codes and descriptors 
to our systems for payment on a quarterly basis. We have only very 
recently received one such request for coding and payment of a new 
brachytherapy source since we added separate APC payment beginning in 
CY 2005 for the three brachytherapy sources discussed above. We will 
evaluate this source prior to our final rule for CY 2006. Therefore, we 
are not proposing any coding changes to the sources of brachytherapy 
for CY 2006 at this time. Table 26 below includes a list of the 
separately payable brachytherapy

[[Page 42737]]

sources that we are proposing to continue for CY 2006.

VIII. Proposed Coding and Payment for Drug Administration

(If you choose to comment on issues in this section, please include 
the caption ``Drug Administration'' at the beginning of your 
comment.)

A. Background

    From the start of the OPPS until the end of CY 2004, three HCPCS 
codes were used to bill drug administration services provided in the 
hospital outpatient department:
     Q0081 (Infusion therapy, using other than chemotherapeutic 
drugs, per visit)
     Q0083 (Chemotherapy administration by other than infusion 
technique only, per visit)
     Q0084 (Chemotherapy administration by infusion technique 
only, per visit) A fourth OPPS drug administration HCPCS code, Q0085 
(Administration of chemotherapy by both infusion and another route, per 
visit) was active from the beginning of the OPPS through the end of CY 
2003.
    Each of these four HCPCS codes mapped to an APC (that is, Q0081 
mapped to APC 0120, Q0083 mapped to APC 0116, Q0084 mapped to APC 0117, 
and Q0085 mapped to APC 0118), and APC payment rates for these codes 
were made on a per-visit basis. The per-visit payment included payment 
for all hospital resources (except separately payable drugs) associated 
with the drug administration procedures. For CY 2004, we discontinued 
using HCPCS code Q0085 to identify drug administration services, moving 
to a combination of HCPCS codes Q0083 and Q0084 that allowed more 
accurate calculations when determining OPPS payment rates.
    In response to comments we received concerning the available 
opportunities to gather additional drug administration data (and 
subsequently facilitate development of more accurate payment rates for 
drug administration services in future years) and to reduce hospital 
administrative burden, we proposed for the CY 2005 OPPS to change our 
coding and payment methodologies related to drug administration 
services.
    After examining comments and suggestions, including recommendations 
of the APC Panel, we adopted a crosswalk for the CY 2005 OPPS that 
identified all active CPT drug administration codes and the 
corresponding Q-codes, which hospitals had previously used to report 
their charges for the procedures. Hospitals were instructed to begin 
billing CPT codes for drug administration services in the hospital 
outpatient department effective January 1, 2005.
    Payment rates for CY 2005 drug administration services were set 
using CY 2003 claims data. These data reflected per-visit costs 
associated with the four Q-codes listed above. To allow for the time 
necessary to collect data at the more specific CPT code level and to 
continue accurate payments based on available claims data, we used the 
Q-code crosswalk to map CPT drug administration codes to existing drug 
administration APCs. While hospitals were instructed to bill all 
relevant CPT codes that describe the services provided, the Outpatient 
Code Editor (OCE) collapsed payments for drug administration services 
attributed to the same APC and paid a single APC amount for those 
services for each visit, unless a modifier was used to identify drug 
administration services provided more than once in a separate encounter 
on the same day.

B. Proposed Changes for CY 2006

    In 2004, the CPT Editorial Panel approved several new drug 
administration codes and revised several existing codes for use 
beginning in 2006. For use in the physician office setting in CY 2005, 
we established HCPCS G-codes that correspond with the expected new CPT 
codes that will become active in 2006.
    For CY 2006 OPPS billing purposes, we are proposing to continue our 
policy of using CPT codes to bill for drug administration services 
provided in the hospital outpatient department. We anticipate that the 
current CPT codes will no longer be effective in CY 2006, and, 
therefore, we are proposing a CY 2006 crosswalk that maps current CPT 
codes to the CPT drug administration codes approved by the CPT 
Editorial Panel in 2004, which correspond to the G-codes used in the 
physician office setting for CY 2005 and which we expect to become 
active CPT codes for 2006.
    The OPPS drug administration payment rates that we are proposing 
for CY 2006 are dependent on CY 2004 data

[[Page 42738]]

containing per-visit charges for HCPCS codes Q0081, Q0083, and Q0084. 
While HCPCS code Q0085 was used to inform payment rates for drug 
administration APCs for CY 2005, there are no data from this code to 
develop payment rates for drug administration APCs for CY 2006 because 
this code was not used in CY 2004. We are proposing to map the new CPT 
codes to existing drug administration APC groups (APC 0116, APC 0117, 
and APC 0120) as we did in CY 2005. Again, hospitals would be expected 
to bill all relevant CPT codes for services provided, but payment for 
services within the same APC group would be collapsed by the OCE into a 
single per-visit APC payment, unless a modifier is used to identify 
drug administration services provided more than once in a separate 
encounter on the same day.
    Table 27 shows the crosswalk from the CY 2005 CPT codes to the 
expected CY 2006 CPT codes (indicated by definition and 2005 HCPCS G-
code) and includes the proposed CY 2006 status indicators and APC 
payment groups for these services. At its February 2005 meeting, the 
APC Panel recommended that this crosswalk be used to establish drug 
administration payments for the CY 2006 OPPS. Therefore, we are 
proposing to use the crosswalk as illustrated in Table 27 to assign 
drug administration services to APC payment groups for CY 2006 OPPS.

C. Proposed Changes to Vaccine Administration

    Hospitals currently use three HCPCS G-codes to indicate the 
administration of the following vaccines that have specific statutory 
coverage:
     G0008--Administration of Influenza Virus Vaccine
     G0009--Administration of Pneumococcal Vaccine
     G0010--Administration of Hepatitis B Vaccine
    HCPCS codes G0008 and G0009 are exempt from beneficiary coinsurance 
and deductible applications and, as such, payment has been made outside 
of the OPPS since CY 2003 based on reasonable cost. We have made 
payment for HCPCS code G0010 through a clinical APC (that is, APC 0355) 
that included vaccines along with this vaccine administration code. 
Additional vaccine administration codes have been packaged or not paid 
under the OPPS.
    We believe that HCPCS codes G0008, G0009 and G0010 are clinically 
similar and comparable in resource use to one another and to the 
administration of other immunizations and other therapeutic, 
prophylactic, or diagnostic injections. The appropriate APC assignment 
for these vaccine administration services is newly reconfigured APC 
0353 (``Injection, Level II''). However, because of their statutory 
exemption regarding beneficiary deductible and coinsurance, for 
operational reasons we are unable to include HCPCS codes G0008 and 
G0009 in an APC with codes that do not share this exemption.
    Therefore, for CY 2006, we are proposing to map HCPCS codes G0008 
and G0009 to new APC 0350 (Administration of flu and PPV vaccines). As 
dictated by statute, HCPCS codes G0008 and G0009 will continue to be 
exempt from beneficiary coinsurance and deductible.
    We are also proposing to change the status indicator for HCPCS code 
G0010 from ``K'' (Separate APC Payment) to ``B'' (Not paid under OPPS; 
Alternate code may be available), and to change the status indicators 
for vaccine administration codes 90471 and 90472 from ``N'' (Packaged) 
to ``X'' (Separate APC Payment), in agreement with the recommendation 
of the APC Panel to unpackage these services. Hospitals would code for 
hepatitis B vaccine administration using codes 96471 or 96472 (as 
appropriate), and payment would be mapped to reconfigured APC 0353 
(``Injection, Level II'') that will include other injection services 
that are clinically similar and comparable in resource use.
    Additionally, in order to pay appropriately for services that we 
believe are clinically similar and comparable in resource use and, 
barring technical restrictions, would otherwise be assigned to the same 
APC, we are proposing to calculate a combined median cost for all 
services assigned to APC 0350 and APC 0353 that would then serve as the 
median cost for both APCs. This combined median would be calculated 
using charges converted to costs from claims for services in both APCs 
and would have the effect of making the OPPS payment rates for APC 0350 
and APC 0353 identical, although beneficiary copayment and deductible 
would not be applied to services in APC 0350.
    In addition, we are proposing to change the status indicators for 
vaccine administration codes 90473 and 90474 from ``E'' (Not paid under 
OPPS) to ``S'' (Paid under OPPS) and make payments for these services 
when they are covered through proposed APC 1491 (New Technology--Level 
IA ($0-$10)). Finally, we are proposing to change the status indicators 
for the four remaining vaccine administration codes involving physician 
counseling (90465, 90466, 90467 and 90468) from ``N'' (Packaged) to 
``B'' (Not paid under OPPS; Alternate code may be available). Hospitals 
providing immunization services with physician counseling would use the 
vaccine administration codes 90471, 90472, 90473, and 90473 to report 
such services, as we do not believe the provision of physician 
counseling significantly affects the hospital resources required for 
administration of immunizations. Table 28 displays the changes that we 
are proposing for CY 2006.

IX. Hospital Coding for Evaluation and Management (E/M) Services

(If you choose to comment on issues in this section, please include 
the caption ``E/M Services'' at the beginning of your comment.)

    In the November 15, 2004 final rule with comment period (69 FR 
65838), we noted our primary concerns and direction for developing the 
proposed coding guidelines for emergency department and clinic visits. 
We intend to make available for public comment the proposed coding 
guidelines that we are considering through the CMS OPPS Web site as 
soon as we have completed them. We will notify the public through our 
listserve when these proposed guidelines become available. To subscribe 
to this listserve, please go to the following CMS Web site: http://www.cms.hhs.gov/medlearn/listserv.asp
 and follow the directions to the 

OPPS listserve. We will provide ample opportunity for the public to 
comment on the proposal.
    We will continue to be considerate of the time necessary to educate 
clinicians and coders on the use of the new codes and guidelines and 
for hospitals to modify their systems. We anticipate providing a 
minimum notice of between 6 and 12 months prior to implementation of 
the new evaluation and management codes and guidelines. We will 
continue developing and testing the new codes even though we have not 
yet made plans for their implementation.

X. Proposed Payment for Blood and Blood Products

(If you choose to comment on issues in this section, please include 
the caption ``Blood and Blood Products'' at the beginning of your 
comment.)

A. Background

    Since the implementation of the OPPS in August 2000, separate 
payments have been made for blood and blood products through APCs 
rather than packaging them into payments for the procedures with which 
they were administered. Hospital payments for the costs of blood and 
blood products, as well as the costs of collecting, processing, and 
storing blood and blood products, are made through the OPPS payments 
for specific blood product APCs. On April 12, 2001, CMS issued the 
original billing guidance for blood products to hospitals (Program 
Transmittal A-01-50). In response to requests for clarification of 
these instructions, CMS issued Transmittal 496 on March 4, 2005. The 
comprehensive billing guidelines in the Transmittal also addressed 
specific concerns and issues related to billing for blood-related 
services, which the public had brought to our attention.
    In CY 2000, payments for blood and blood products were established 
based on external data provided by commenters due to limited Medicare 
claims data. From CY 2000 to CY 2002, payment rates for blood and blood 
products were updated for inflation. For CY 2003, as described in the 
November 1, 2002 final rule with comment period (67 FR 66773), we 
applied a special dampening methodology to blood and blood products 
that had significant reductions in payment rates from CY 2002 to CY 
2003, when median costs were first calculated from hospital claims. 
Using the dampening methodology, we limited the decrease in payment 
rates for blood and blood products to approximately 15 percent. For CY 
2004, as recommended by the APC Panel, we froze payment rates for blood 
and blood products at CY 2003 levels as we studied concerns raised by 
commenters and presenters at the August 2003 and February 2004 APC 
Panel meetings.
    For CY 2005, we established new APCs that allowed each blood 
product to be assigned to its own separate APC, as several of the 
previous blood product APCs contained multiple blood products with no 
clinical homogeneity or whose product-specific median costs may not 
have been similar. Some of the blood product HCPCS codes were 
reassigned to the new APCs (Table 34 of the November 15, 2004 final 
rule with comment period (69 FR 65819)).
    We also noted in the November 15, 2004 final rule with comment 
period that public comments to previous OPPS rules had stated that the 
CCRs that were used to adjust charges to costs for blood products in 
past years were too low. Past commenters indicated that this approach 
resulted in an underestimation of the true hospital costs for blood and 
blood products. In response to these comments and APC Panel 
recommendations from their February 2004 and September 2004 meetings, 
we conducted a thorough analysis of the OPPS CY 2003 claims (used to 
calculate the CY 2005 APC payment rates) to compare CCRs between those 
hospitals reporting a blood-specific cost center and those hospitals 
defaulting to the overall hospital CCR in the conversion of their blood 
product charges to costs. As a result of this analysis, we observed a 
significant difference in CCRs utilized for conversion of blood product 
charges to costs for those hospitals with and without blood-specific 
cost centers. The median hospital blood-specific CCRs were almost two 
times the median overall hospital CCR. As discussed in the November 15, 
2004 final rule with comment period, we applied a methodology for 
hospitals not reporting a blood-specific cost center, which simulated a 
blood-specific CCR for each hospital that we then used to convert 
charges to costs for blood products. Thus, we developed simulated 
medians for all blood and blood products based on CY 2003 hospital 
claims data (69 FR 65816).

[[Page 42741]]

    For CY 2005, we also identified a subset of blood products that had 
less than 1,000 units billed in CY 2003. For these low-volume blood 
products, we based the CY 2005 payment rate on a 50/50 blend of CY 2004 
product-specific OPPS median costs and the CY 2005 simulated medians 
based on the application of blood-specific CCRs to all claims. We were 
concerned that, given the low frequency in which these products were 
billed, a few occurrences of coding or billing errors may have led to 
significant variability in the median calculation. The claims data may 
not have captured the complete costs of these products to hospitals as 
fully as possible. This low-volume adjustment methodology also allowed 
us to further study the issues raised by commenters and by presenters 
at the September 2004 APC Panel meeting, without putting beneficiary 
access to these low-volume blood products at risk.

B. Proposed Changes for CY 2006

    For CY 2006, we are proposing to continue to make separate payments 
for blood and blood products under the OPPS through individual APCs for 
each product. We are also proposing to establish payment rates for 
these blood and blood products by using the same simulation methodology 
described in the November 15, 2004 final rule with comment period (69 
FR 65816), which utilized hospital-specific actual or simulated CCRs 
for blood cost centers to convert hospital charges to costs, with an 
adjustment applied to some products. We continue to believe that using 
blood-specific CCRs applied to hospital claims data will result in 
reasonably accurate payments that more fully reflect hospitals' true 
costs of providing blood and blood products than our general 
methodology of defaulting to the overall hospital CCR when more 
specific CCRs are unavailable.
    For blood and blood products whose CY 2006 simulated medians 
experienced a decrease of more than 10 percent in comparison to their 
CY 2005 payment medians, we are proposing to limit the decrease in 
medians to 10 percent. Therefore, overall we are proposing to base 
median costs for blood and blood products in CY 2006 on the greater of: 
(1) Simulated medians calculated using CY 2004 claims data; or (2) 90 
percent of the APC payment median for CY 2005 for such products. We 
recognize that possible errors in hospital billing or coding for blood 
products in CY 2004 may have contributed to these decreases in medians. 
In particular, hospitals may have been uncertain about which of their 
many different costs for providing blood and blood products should be 
captured in their charges for the products, based on variations in the 
specific circumstances of the services they provided. In addition, the 
six products affected by the proposed CY 2006 adjustment policy all 
were relatively low volume with fewer than 7,000 units billed in CY 
2004. Three of these products were affected by the low-volume payment 
adjustment for CY 2005 because there were less than 1,000 units billed, 
and their CY 2005 payment medians would have decreased without the 
adjustment. In the interim, as hospitals become more familiar with the 
comprehensive billing guidelines for blood and blood products that are 
described in Program Transmittal 496, (Change Request 3681 dated March 
4, 2005), we acknowledge the need to protect beneficiaries' access to a 
safe blood supply and are proposing to do so by limiting significant 
decreases in payment rates for blood and blood products from CY 2005 to 
CY 2006. We expect that our billing guidance will assist hospitals in 
more fully including all appropriate costs for providing blood and 
blood products in their charges for those products, so that our data 
for CY 2005, which will be used to set median costs for blood and blood 
products in the CY 2007 OPPS, should more accurately capture the 
hospital costs associated with each different blood product.
    Displayed in Table 29 is the list of blood product HCPCS codes with 
their proposed CY 2006 payment medians. Overall, medians from CY 2005 
and CY 2006 were relatively stable, and we expect that as hospitals 
improve their billing and coding practices, medians based on historical 
hospital claims data should continue to become more consistent and 
reflective of all hospital costs. For blood and blood products whose CY 
2006 simulated median would have experienced a decrease from CY 2005 to 
CY 2006 of greater than 10 percent, the adjusted median is shown.
    Therefore, for CY 2006, we are proposing to establish payment rates 
for blood and blood products under the OPPS by using the same 
simulation methodology described in the November 15, 2004 final rule 
with comment period (69 FR 65816). For blood and blood products whose 
2006 medians would have otherwise experienced a decrease of more than 
10 percent in comparison with their CY 2005 payment rates, we are 
proposing to adjust the simulated medians by limiting their decrease to 
10 percent.

    In addition, we are proposing to change the status indicator for 
CPT code 85060 (Blood smear, peripheral, interpretation by physician 
with written report) from ``X'' (separately paid under the OPPS) to 
``B'' (not paid under the OPPS). When a hospital provides a physician 
interpretation of an abnormal peripheral blood smear interpretation for 
a hospital outpatient, the charge for the facility resources associated 
with the interpretation should be bundled into the charge reported for 
the ordered hematology lab service, such as, CPT code 85007 (Blood 
count; blood smear, microscopic examination with manual differential 
WBC count) or CPT code 85008 (Blood count; blood smear, microscopic 
examination without manual differential WBC count), which are paid 
under the Clinical Laboratory Fee Schedule (CLFS). A physician 
interpretation of an abnormal peripheral blood smear is considered a 
routine part of the ordered hematology lab service, such as CPT codes 
85007 and 85008 paid under the CLFS, so hospitals would receive 
duplicate payment for the facility resources associated with a 
physician's blood smear interpretation if we were to continue to pay 
separately for CPT code 85060 under the OPPS for hospital outpatients. 
Therefore, for CY 2006, we are proposing to discontinue payment under 
the OPPS for CPT code 85060 by changing its status indicator from ``X'' 
to ``B.''

XI. Proposed Payment for Observation Services

(If you choose to comment on issues in this section, please include 
the caption ``Observation Services'' at the beginning of your 
comment.)

A. Background

    Observation care is a well-defined set of specific, clinically 
appropriate services, which include ongoing short-term treatment, 
assessment, and reassessment, before a decision can be made regarding 
whether patients will require further treatment as hospital inpatients 
or if they are able to be discharged from the hospital. Observation 
status is commonly assigned to patients with unexpectedly prolonged 
recovery after surgery and to patients who present to the emergency 
department and who then require a significant period of treatment or 
monitoring before a decision is made concerning their next placement. 
For a detailed discussion of the clinical and payment history of 
observation services, refer to the November 1, 2002 final rule with 
comment period (67 FR 66794).
    Before the implementation of the OPPS in CY 2000, payment for 
observation care was made on a reasonable cost basis. With the 
initiation of the OPPS, costs for observation services were packaged 
into payments for the services with which the observation care was 
associated but no separate payment for observation services was 
implemented.
    For CY 2002, we implemented separate payment for observation 
services (APC 0339) under the OPPS for three medical conditions (chest 
pain, congestive heart failure, and asthma). Additional criteria, such 
as the billing of select diagnosis codes, an evaluation and management 
service, a minimum and maximum number of observation hours, and 
provision of certain condition-specific diagnostic tests, along with 
documentation of the physician's determination that the patient would 
benefit from observation care, were also required in order for 
hospitals to receive the separate APC payment (APC 0339) for 
observation services.
    Taking into account numerous comments from providers about the 
increased administrative burden caused by reporting requirements 
associated with payment for APC 0339 and after reviewing comments and 
recommendations by the APC Panel, we removed the mandated diagnostic 
testing requirements beginning in CY 2005 (Transmittal 514, Change 
Request 3756, released March 30, 2005). Hospitals were instructed to 
rely on clinical judgment in combination with internal and external 
quality review processes to ensure that appropriate diagnostic testing 
is provided for patients receiving high quality, medically necessary 
observation care. In an effort to further reduce administrative burden 
related to accurate billing and in response to suggestions from 
hospitals and the APC Panel, effective January 1, 2005, we clarified 
our instructions for counting time in observation care to end at the 
time the outpatient is actually discharged from the hospital or 
admitted as an inpatient. Our expectation was that specific, medically 
necessary observation services were being provided to the patient up 
until

[[Page 42743]]

the time of discharge. However, we did not expect reported observation 
time to include the time patients remain in the observation area after 
treatment is finished for reasons such as waiting for transportation 
home.
    In updating the CY 2005 OPPS, we also looked at CY 2003 claims data 
for all packaged visit-related observation care for all medical 
conditions in order to determine whether or not there were other 
diagnoses that would be candidates for separately payable observation 
services. This year, we again reviewed the most recent claims data (CY 
2004) for packaged and unpackaged observation services to assess the 
current appropriateness of the three medical conditions for separately 
payable observation services and to determine if the list of diagnosis 
codes was complete for those conditions. The APC Panel recommended at 
the February 2005 APC Panel meeting that CMS expand the list of 
diagnoses eligible for separate observation payments.
    The diagnoses currently associated with the three medical 
conditions continue to be frequently reported on OPPS visit-related 
claims with packaged observation services, and there are a large number 
of claims for separately payable observation care for the three medical 
conditions. At this time, our data show almost 80,000 claims from CY 
2004 for separately payable observation services, compared with 67,182 
for CY 2003 hospital claims. We have also explored other diagnoses that 
appeared in hospital claims data with packaged observation services. 
However, the data on packaged observation services continue to be 
incomplete and unreliable, reported using a number of different CPT 
codes with ``per day'' in their code descriptors. Some hospitals appear 
to be reporting observation services per day, while others appear to be 
reporting each hour of observation care as one unit, as we instructed 
them to do when reporting HCPCS code G0244 for separately payable 
observation. As described in section XI.B. of this preamble, we are 
proposing to make changes to hospital coding for all observation 
services for CY 2006, both separately payable and packaged. We are 
currently not convinced that there are other conditions for which there 
is a well-defined set of hospital services that are distinct from the 
services provided during a clinic or emergency visit. Moreover, 
hospital data from CY 2004 do not reflect our CY 2005 changes in 
separately payable observation policy. We also seek to gain additional 
experience with more consistent hospital billing for observation 
services, both packaged and separately payable, to guide our future 
analyses of observation care. Thus, we believe it is premature to 
expand the conditions for which we would separately pay for visit-
related observation services.

B. Proposed CY 2006 Coding Changes for Observation Services

    In response to comments received regarding the continuing 
administrative burden on hospitals when attempting to differentiate 
between packaged and separately payable observation services for 
purposes of billing correctly, and recommendations put forward by the 
APC Panel and participants at the February 2005 APC Panel meeting, we 
are proposing two changes in payment policy for observation services in 
CY 2006. First, we are proposing to discontinue HCPCS codes G0244 
(Observation care by facility to patient), G0263 (Direct admission with 
CHF, CP, asthma), and G0264 (Assessment other than CHF, CP, asthma) and 
to create two new HCPCS codes to be used by hospitals to report all 
observation services whether separately payable or packaged, and direct 
admission for observation care:
     GXXXX--Hospital observation services, per hour
     GYYYY--Direct admission of patient for hospital 
observation care
    Second, we are proposing to shift determination of whether or not 
observation services are separately payable under APC 0339 from the 
hospital billing department to the OPPS claims processing logic. That 
is, hospitals would bill GXXXX when observation services are provided 
to any patient admitted to ``observation status,'' regardless of the 
patient's status as an inpatient or outpatient. Hospitals would 
additionally bill GYYYY when observation services are the result of a 
direct admission to ``observation status'' without an associated 
emergency room visit, hospital outpatient clinic visit, or critical 
care service on the day of or day before the observation services. Both 
of these new HCPCS codes would be assigned a new status indicator that 
would trigger OCE logic during the processing of the claim to determine 
if the observation service is packaged with the other separately 
payable hospital services provided or if a separate APC payment for 
observation services is appropriate in accordance with the criteria 
discussed below in section XI.C. of this preamble. In addition, we are 
proposing to change the status indicator for CPT codes 99217 through 
99220 and 99234 through 99236 from ``N'' (packaged) to ``B'' (code not 
recognized by OPPS). We will expect hospitals to utilize GXXXX to 
accurately report all observation services provided to beneficiaries, 
whether the observation would be packaged or separately payable, to 
assist us in developing consistent and complete hospital claims data 
regarding the utilization and costs of observation services. The units 
of service reported with GXXXX would equal the number of hours the 
patient is in observation status.

C. Proposed Criteria for Separately Payable Observation Services (APC 
0339)

    For CY 2006, we are proposing to continue applying the existing CY 
2005 criteria (69 FR 65830), which determine if hospitals may receive 
separate payment for medically necessary observation care provided to a 
patient with congestive heart failure, chest pain, or asthma. In 
addition, we are proposing to continue our policy of packaging payment 
for all other observation services into the payments for the separately 
payable services with which the observation service is reported. As 
explained previously in section XI.B. of this section, the only changes 
we are proposing are related to the codes hospitals would use to report 
observation services, and the point at which a payment determination is 
made. Rather than requiring the hospital to determine prior to claims 
submission whether patient condition and the services furnished meet 
the criteria for payment of APC 0339, that determination would shift to 
the claims processing modules installed by the fiscal intermediaries to 
process all OPPS bills, thereby reducing the administrative burden on 
hospitals.
    Criteria for separate observation service payments include 
documentation of specific ICD-9-CM diagnostic codes (International 
Classification of Diseases, Ninth Edition, Clinical Modification); the 
length of time a patient is in observation status; hospital services 
provided bef
