                              Drug Coverage
 
Sec.  423.329  Determination of payments.

    (a) Subsidy payments--(1) Direct subsidy. CMS makes a direct subsidy 
payment for each Part D eligible beneficiary enrolled in a Part D plan 
for a month equal to the amount of the plan's approved standardized bid, 
adjusted for health status (as determined under Sec.  423.329(b)(1)), 
and reduced by the base beneficiary premium for the plan (as determined 
under Sec.  423.286(c) and adjusted in Sec.  423.286(d)(1)). The direct 
subsidy payment may be increased by the excess amount of a negative 
premium as described in Sec.  423.286(d)(1), if applicable.
    (2) Subsidy through reinsurance. CMS makes reinsurance subsidy 
payments as provided under paragraph (c) of this section.
    (3) Low-income cost-sharing subsidy. CMS makes low-income cost-
sharing subsidy payments as provided under paragraph (d) of this 
section.
    (b) Health status risk adjustment--(1) Establishment of risk 
factors. CMS establishes an appropriate methodology for adjusting the 
standardized bid amount to take into account variation in costs for 
basic prescription drug coverage among Part D plans based on the 
differences in actuarial risk of different enrollees being served. Any 
risk adjustment is designed in a manner so as to be budget neutral in 
the aggregate to the risk of the Part D eligible individuals who enroll 
in Part D plans.
    (2) Considerations. In establishing the methodology under paragraph 
(b)(1) of this section, CMS takes into account the similar methodologies 
used under Sec.  422.308(c) of this chapter to adjust payments to MA 
organizations for benefits under the original Medicare fee-for-service 
program option.
    (3) Data collection. In order to carry out this paragraph, CMS 
requires--
    (i) PDP sponsors to submit data regarding drug claims that can be 
linked at the individual level to Part A and Part B data in a form and 
manner similar to the process provided under Sec.  422.310 of this 
chapter and other information as CMS determines necessary; and
    (ii) MA organizations that offer MA-PD plans to submit data 
regarding drug claims that can be linked at the individual level to 
other data that the organizations are required to submit to CMS in a 
form and manner similar to the process provided under Sec.  422.310 of 
this chapter and other information as CMS determines necessary.
    (4) Publication. At the time of publication of risk adjustment 
factors under Sec.  422.312(a)(1)(ii) of this chapter, CMS publishes the 
risk adjusters established under this paragraph of this section for the 
upcoming calendar year.
    (c) Reinsurance payment amount--(1) General rule. The reinsurance 
payment amount for a Part D eligible individual enrolled in a Part D 
plan for a coverage year is an amount equal to 80 percent of the 
allowable reinsurance costs attributable to that portion of gross 
covered prescription drug costs incurred in the coverage year after the 
individual has incurred true out-of-pocket costs that exceed the annual 
out-of-pocket threshold specified in Sec.  423.104(d)(5)(iii).

    (2) Payment method. Payments under this section are based on a 
method that CMS determines.
    (i) Payments during the coverage year. CMS establishes a payment 
method by which payments of amounts
    under this section are made on a monthly basis during a year based 
on either estimated or incurred allowable reinsurance costs.
    (ii) Final payments. CMS reconciles the payments made during the 
coverage year to final actual allowable reinsurance costs as provided in 
Sec.  423.343(c).
    (3) Special rules for private fee-for-service Plans offering 
prescription drug coverage. CMS determines the amount of reinsurance 
payments for private fee-for-service plans as defined by Sec.  
422.4(a)(3) of this chapter offering qualified prescription drug 
coverage using a methodology that--
    (i) Bases the amount on CMS' estimate of the amount of the payments 
that are payable if the plan were an MA-PD plan described in section 
1851(a)(2)(A)(i) of the Act; and
    (ii) Takes into account the average reinsurance payments made under 
Sec.  423.329(c) for populations of similar risk under MA-PD plans 
described in section 1851(a)(2)(A)(i) of the Act.
    (d) Low-income cost sharing subsidy payment amount--(1) General 
rule. The low-income cost-sharing subsidy payment amount on behalf of a 
low-income subsidy eligible individual enrolled in a Part D plan for a 
coverage year is the amount described in Sec.  423.782.
    (2) Payment method. Payments under this section are based on a 
method that CMS determines.
    (i) Interim payments. CMS establishes a payment method by which 
interim payments of amounts under this section are made during a year 
based on the low-income cost-sharing assumptions submitted with plan 
bids under Sec.  423.265(d)(2)(iv) and negotiated and approved under 
Sec.  423.272.
    (ii) Final payments. CMS reconciles the interim payments to actual 
incurred low-income cost-sharing costs as provided in Sec.  423.343(d).
