PART 413_PRINCIPLES OF REASONABLE COST REIMBURSEMENT; PAYMENT FOR END-STAGE 
 
                     Subpart E_Payments to Providers
 
Sec.  413.64  Payments to providers: Specific rules.

    (a) Reimbursement on a reasonable cost basis. Providers of services 
paid on the basis of the reasonable cost of services furnished to 
beneficiaries will receive interim payments approximating the actual 
costs of the provider. These payments will be made on the most 
expeditious schedule administratively feasible but not less often than 
monthly. A retroactive adjustment based on actual costs will be made at 
the end of a reporting period.
    (b) Amount and frequency of payment. Medicare states that providers 
of services will be paid the reasonable cost of services furnished to 
beneficiaries. Since actual costs of services cannot be determined until 
the end of the accounting period, the providers must be paid on an 
estimated cost basis during the year. While Medicare provides that 
interim payments will be made no less often than monthly, intermediaries 
are expected to make payments on the most expeditious basis 
administratively feasible. Whatever estimated cost basis is used for 
determining interim payments during the year, the intent is that the 
interim payments shall approximate actual costs as nearly as is 
practicable so that the retroactive adjustment based on actual costs 
will be as small as possible.
    (c) Interim payments during initial reporting period. At the 
beginning of the program or when a provider first participates in the 
program, it will be necessary to establish interim rates of payment to 
providers of services. Once a provider has filed a cost report under the 
Medicare program, the cost report may be used as a basis for determining 
the interim rate of reimbursement for the following period. However, 
since initially there is no previous history of cost under the program, 
the interim rate of payment must be determined by other methods, 
including the following:
    (1) If the intermediary is already paying the provider on a cost or 
cost-related basis, the intermediary will adjust its rate of payment to 
the program's principles of reimbursement. This rate may be either an 
amount per inpatient day, or a percent of the provider's charges for 
services furnished to the program's beneficiaries.
    (2) If an organization other than the intermediary is paying the 
provider for services on a cost or cost-related basis, the intermediary 
may obtain from that organization or from the provider itself the rate 
of payment being used and other cost information as may be needed to 
adjust that rate of payment to give recognition to the program's 
principles of reimbursement.
    (3) It no organization is paying the provider on a cost or cost-
related basis, the intermediary will obtain the previous year's 
financial statement from

[[Page 652]]

the provider. By analysis of such statement in light of the principles 
of reimbursement, the intermediary will compute an appropriate rate of 
payment.
    (4) After the initial interim rate has been set, the provider may at 
any time request, and be allowed, an appropriate increase in the 
computed rate, upon presentation of satisfactory evidence to the 
intermediary that costs have increased. Likewise, the intermediary may 
adjust the interim rate of payment if it has evidence that actual costs 
may fall significantly below the computed rate.
    (d) Interim payments for new providers. (1) Newly-established 
providers will not have cost experience on which to base a determination 
of an interim rate of payment. In such cases, the intermediary will use 
the following methods to determine an appropriate rate:
    (i) If there is a provider or providers comparable in substantially 
all relevant factors to the provider for which the rate is needed, the 
intermediary will base an interim rate of payment on the costs of the 
comparable provider.
    (ii) If there are no substantially comparable providers from whom 
data are available, the intermediary will determine an interim rate of 
payment based on the budgeted or projected costs of the provider.
    (2) Under either method, the intermediary will review the provider's 
cost experience after a period of three months. If need for an 
adjustment is indicated, the interim rate of payment will be adjusted in 
line with the provider's cost experience.
    (e) Interim payments after initial reporting period. Interim rates 
of payment for services provided after the initial reporting period will 
be established on the basis of the cost report filed for the previous 
year covering Medicare services. The current rate will be determined--
whether on a per diem or percentage of charges basis--using the previous 
year's costs of covered services and making any appropriate adjustments 
required to bring, as closely as possible, the current year's rate of 
interim payment into agreement with current year's costs. This interim 
rate of payment may be adjusted by the intermediary during an accounting 
period if the provider submits appropriate evidence that its actual 
costs are or will be significantly higher than the computed rate. 
Likewise, the intermediary may adjust the interim rate of payment if it 
has evidence that actual costs may fall significantly below the computed 
rate.
    (f) Retroactive adjustment. (1) Medicare provides that providers of 
services will be paid amounts determined to be due, but not less often 
than monthly, with necessary adjustments due to previously made 
overpayments or underpayments. Interim payments are made on the basis of 
estimated costs. Actual costs reimbursable to a provider cannot be 
determined until the cost reports are filed and costs are verified. 
Therefore, a retroactive adjustment will be made at the end of the 
reporting period to bring the interim payments made to the provider 
during the period into agreement with the reimbursable amount payable to 
the provider for the services furnished to program beneficiaries during 
that period.
    (2) In order to reimburse the provider as quickly as possible, an 
initial retroactive adjustment will be made as soon as the cost report 
is received. For this purpose, the costs will be accepted as reported, 
unless there are obvious errors or inconsistencies, subject to later 
audit. When an audit is made and the final liability of the program is 
determined, a final adjustment will be made.
    (3) To determine the retroactive adjustment, the amount of the 
provider's total allowable cost apportioned to the program for the 
reporting year is computed. This is the total amount of reimbursement 
the provider is due to receive from the program and the beneficiaries 
for covered services furnished during the reporting period. The total of 
the interim payments made by the program in the reporting year and the 
deductibles and coinsurance amounts receivable from beneficiaries is 
computed. The difference between the reimbursement due and the payments 
made is the amount of the retroactive adjustment.
    (g) Accelerated payments to providers. Upon request, an accelerated 
payment may be made to a provider of services that is not receiving 
periodic interim

[[Page 653]]

payments under paragraph (h) of this section if the provider has 
experienced financial difficulties due to a delay by the intermediary in 
making payments or in exceptional situations, in which the provider has 
experienced a temporary delay in preparing and submitting bills to the 
intermediary beyond its normal billing cycle. Any such payment must be 
approved first by the intermediary and then by CMS. The amount of the 
payment is computed as a percentage of the net reimbursement for 
unbilled or unpaid covered services. Recovery of the accelerated payment 
may be made by recoupment as provider bills are processed or by direct 
payment.
    (h) Periodic interim payment method of reimbursement--(1) Covered 
services furnished before July 1, 1987. In addition to the regular 
methods of interim payment on individual provider billings for covered 
services, the periodic interim payment (PIP) method is available for 
Part A hospital and SNF inpatient services.
    (2) Covered services furnished on or after July 1, 1987. Effective 
with claims received on or after July l, 1987, or as otherwise 
specified, the periodic interim payment (PIP) method is available for 
the following:
    (i) Part A inpatient services furnished in hospitals that are 
excluded from the prospective payment systems, as specified in Sec.  
412.1(a)(1) of this chapter under subpart B of part 412 of this 
subchapter, or are paid under the prospective payment systems described 
in subpart N, O, and P of part 412 of this chapter.
    (ii) Part A services furnished in hospitals receiving payment in 
accordance with a demonstration project authorized under section 402(a) 
of Public Law 90-248 (42 U.S.C. 1395b-1) or section 222(a) of Public Law 
92-603 (42 U.S.C. 1395b-1 (note)), or a State reimbursement control 
system approved under section 1886(c) of the Act and subpart C of part 
403 of this chapter, if that type of payment is specifically approved by 
CMS as an integral part of the demonstration or control system. If that 
type of payment is not an integral part of the demonstration or control 
system, PIP is available for the hospital under paragraph (h)(1)(i) of 
this section for hospitals excluded from the prospective payment systems 
or under Sec.  412.116(b) of this chapter for prospective payment 
hospitals.
    (iii) Part A SNF services furnished in cost reporting periods 
beginning before July 1, 1998. (For services furnished in subsequent 
cost reporting periods, see Sec.  413.350 regarding periodic interim 
payments for skilled nursing facilities).
    (iv) Part A services furnished in hospitals paid under the 
prospective payment system, including distinct part psychiatric or 
rehabilitation units, as described in Sec.  412.116(b) of this chapter.
    (v) Services furnished in a hospice as specified in part 418 of this 
chapter. Payment on a PIP basis is described in Sec.  418.307 of this 
chapter.
    (vi) Effective for payments made on or after July 1, 2004, inpatient 
CAH services furnished by a CAH as specified in Sec.  413.70. Payment on 
a PIP basis is described in Sec.  413.70(d).
    (3) Any participating provider furnishing the services described in 
paragraphs (h)(1) and (h)(2) of this section that establishes to the 
satisfaction of the intermediary that it meets the following 
requirements may elect to be reimbursed under the PIP method, beginning 
with the first month after its request that the intermediary finds 
administratively feasible:
    (i) The provider's estimated total Medicare reimbursement for 
inpatient services is at least $25,000 a year computed under the PIP 
formula or, in the case of an HHA, either its estimated--
    (A) Total Medicare reimbursement for Part A and Part B services is 
at least $25,000 a year computed under the PIP formula; or
    (B) Medicare reimbursement computed under the PIP formula is at 
least 50 percent of estimated total allowable cost.
    (ii) The provider has filed at least one completed Medicare cost 
report accepted by the intermediary as providing an accurate basis for 
computation of program payment (except in the case of a provider 
requesting reimbursement under the PIP method upon first entering the 
Medicare program).
    (iii) The provider has the continuing capability of maintaining in 
its records the cost, charge, and statistical data

[[Page 654]]

needed to accurately complete a Medicare cost report on a timely basis.
    (4) [Reserved]
    (5) The intermediary's approval of a provider's request for 
reimbursement under the PIP method will be conditioned upon the 
intermediary's best judgment as to whether payment can be made to the 
provider under the PIP method without undue risk of its resulting in an 
overpayment because of greatly varying or substantially declining 
Medicare utilization, inadequate billing practices, or other 
circumstances. The intermediary may terminate PIP reimbursement to a 
provider at any time it determines that the provider no longer meets the 
qualifying requirements or that the provider's experience under the PIP 
method shows that proper payment cannot be made under this method.
    (6) Payment will be made biweekly under the PIP method unless the 
provider requests a longer fixed interval (not to exceed one month) 
between payments. The payment amount will be computed by the 
intermediary to approximate, on the average, the cost of covered 
inpatient or home health services furnished by the provider during the 
period for which the payment is to be made, and each payment will be 
made two weeks after the end of such period of services. Upon request, 
the intermediary will, if feasible, compute the provider's payments to 
recognize significant seasonal variation in Medicare utilization of 
services on a quarterly basis starting with the beginning of the 
provider's reporting year.
    (7) A provider's PIP amount may be appropriately adjusted at any 
time if the provider presents or the intermediary otherwise obtains 
evidence relating to the provider's costs or Medicare utilization that 
warrants such adjustment. In addition, the intermediary will recompute 
the payment immediately upon completion of the desk review of a 
provider's cost report and also at regular intervals not less often than 
quarterly. The intermediary may make a retroactive lump sum interim 
payment to a provider, based upon an increase in its PIP amount, in 
order to bring past interim payments for the provider's current cost 
reporting period into line with the adjusted payment amount. The 
objective of intermediary monitoring of provider costs and utilization 
is to assure payments approximating, as closely as possible, the 
reimbursement to be determined at settlement for the cost reporting 
period. A significant factor in evaluating the amount of the payment in 
terms of the realization of the projected Medicare utilization of 
services is the timely submittal to the intermediary of completed 
admission and billing forms. All providers must complete billings in 
detail under this method as under regular interim payment procedures.
    (i) Bankruptcy or insolvency of provider. If on the basis of 
reliable evidence, the intermediary has a valid basis for believing 
that, with respect to a provider, proceedings have been or will shortly 
be instituted in a State or Federal court for purposes of determining 
whether such provider is insolvent or bankrupt under an appropriate 
State or Federal law, any payments to the provider will be adjusted by 
the intermediary, notwithstanding any other regulation or program 
instruction regarding the timing or manner of such adjustments, to a 
level necessary to insure that no overpayment to the provider is made.
    (j) Interest payments resulting from judicial review--(1) 
Application. If a provider of services seeks judicial review by a 
Federal court (see Sec.  405.1877 of this chapter) of a decision 
furnished by the Provider Reimbursement Review Board or subsequent 
reversal, affirmation, or modification by the Secretary, the amount of 
any award of such Federal court will be increased by interest payable by 
the party against whom the judgment is made (see Sec.  413.153 for 
treatment of interest). The interest is payable for the period beginning 
on the first day of the first month following the 180-day period which 
began on either the date the intermediary made a final determination or 
the date the intermediary would have made a final determination had it 
been done on a timely basis (see Sec. Sec.  405.1835(b) and 405.1841(a) 
of this chapter).
    (2) Amount due. Section 1878(f) of the Act, 42 U.S.C. 1395oo(f), 
authorizes a court to award interest in favor of the prevailing party on 
any amount due as

[[Page 655]]

a result of the court's decision. If the intermediary withheld any 
portion of the amount in controversy prior to the date the provider 
seeks judicial review by a Federal court, and the Medicare program is 
the prevailing party, interest is payable by the provider only on the 
amount not withheld. Similarly, if the Medicare program seeks to recover 
amounts previously paid to a provider, and the provider is the 
prevailing party, interest on the amounts previously paid to a provider 
is not payable by the Medicare program since that amount had been paid 
and is not due the provider.
    (3) Rate. The amount of interest to be paid is equal to the rate of 
return on equity capital (see Sec.  413.157) in effect for the month in 
which the civil action is commenced.

    Example: An intermediary made a final determination on the amount of 
Medicare program reimbursement on June 15, 1974, and the provider 
appealed that determination to the Provider Reimbursement Review Board. 
The Board heard the appeal and rendered a decision adverse to the 
provider. On October 28, 1974, the provider commenced civil action to 
have such decision reviewed. The rate of return on equity capital for 
the month of October 1974 was 11.625 percent. The period for which 
interest is computed begins on January 1, 1975, and the interest 
beginning January 1, 1975, would be at the rate of 11.625 percent per 
annum.
