Medicare Prescription Payment Plan

(a) General. For plan years beginning on or after January 1, 2026, or, in the case of a plan operating on a non-calendar year basis, for the portion of the plan year starting on January 1, 2026, each PDP sponsor offering a prescription drug plan and each MA organization offering an MA-PD plan must provide to any enrollee of such plan, including an enrollee who is a subsidy eligible individual (as defined at § 423.4), the option to elect with respect to a plan year to pay $0 cost sharing at the point of sale and pay cost sharing under the plan in monthly amounts that are capped in accordance with this section.

(b) Definitions. For the purposes of this section, the following definitions apply:

(1) OOP costs for the Medicare Prescription Payment Plan means the out-of-pocket (OOP) cost sharing amount the Part D enrollee is directly responsible for paying.

(i) For the subsequent month calculation of the Part D cost sharing incurred by the Part D enrollee, it includes those Part D cost sharing amounts that the enrollee is responsible for paying after taking into account amounts paid by third-party payers.

(ii) It does not include the covered plan pay amount or other costs defined under section 1860D-2(b)(4)(C) of the Act.

(2) Remaining OOP costs owed by the participant means the sum of out-of-pocket costs for the Medicare Prescription Payment Plan that have not yet billed to the program participant. For example, if a Medicare Prescription Payment Plan participant incurs $2,000 in January 2025 and is billed $166.67, the remaining OOP costs for the Medicare Prescription Payment Plan are $2,000−$166.67 = $1,833.33.

(c) Calculation of the maximum monthly cap on cost-sharing payments. For each month in the plan year for which an enrollee in a PDP or an MA-PD plan has made an election to participate in the Medicare Prescription Payment Plan, the PDP sponsor or MA organization must determine a maximum monthly cap (as defined in paragraph (c)(1) of this section) for such enrollee.

(1) Enrollee monthly payments. For each month an enrollee is participating in the Medicare Prescription Payment Plan, the PDP sponsor or MA organization shall bill such enrollee an amount (not to exceed the maximum monthly cap) for the out-of-pocket costs of such enrollee in such month.

(i) First month maximum monthly cap calculation. For the first month for which the enrollee has made an election to participate in the Medicare Prescription Payment Plan, the maximum monthly cap is an amount determined by calculating the annual out-of-pocket threshold specified in section 1860D-2(b)(4)(B) of the Act minus the incurred costs of the enrollee as described in section 1860D-2(b)(4)(C) of the Act; divided by the number of months remaining in the plan year.

(A) When the out-of-pocket costs incurred in the first month of program participation are less than the maximum monthly cap defined in this paragraph (c)(1)(i), the PDP sponsor or MA organization must bill the participant the lesser of the participant's actual out-of-pocket costs or the first month's maximum monthly cap.

(B) When an enrollee opts into the Medicare Prescription Payment Plan prior to the start of the plan year, the calculation described in this paragraph (c)(1)(i) applies to their first month of active coverage within the plan year.

(ii) Calculation of maximum monthly cap in subsequent months. For subsequent months in the plan year, the maximum monthly cap is an amount determined by calculating the sum of any remaining out-of-pocket costs owed by the enrollee from a previous month that have not yet been billed to the enrollee and any additional out-of-pocket costs incurred by the enrollee; divided by the number of months remaining in the plan year.

(2) Eligible out-of-pocket costs. The calculations described in paragraphs (c)(1)(i) and (ii) of this section apply only to covered Part D drugs, as defined at § 423.100.

(3) Months remaining in the plan year. For the calculations described in paragraphs (c)(1)(i) and (ii) of this section, the number of months remaining in the plan year includes the month for which the cap is being calculated.

(4) Impact on true out-of-pocket cost accumulation. Participation in the Medicare Prescription Payment Plan must have no impact on true out-of-pocket cost accumulation. Costs defined under section 1860D-2(b)(4)(C) of the Act incurred under the Medicare Prescription Payment Plan must still be treated as incurred based on the date each Part D claim is adjudicated.

(5) Prescriptions for an extended day supply. For participants who fill prescriptions for an extended day supply, their OOP costs for the Medicare Prescription Payment Plan for those prescriptions must be attributed to the month the prescription was filled and not be pro-rated over the months covered by the prescription.

(6) Mid-year plan switching. When an individual opts into the Medicare Prescription Payment Plan after switching plans midyear, the new Part D sponsor must calculate the individual's monthly cap for the first month of participation under the new plan using the formula for the calculation of the maximum monthly cap in the first month.

(d) Eligibility and election. An individual is eligible for the Medicare Prescription Payment Plan if they are enrolled in a Part D plan and have not been precluded from participation due to failure to pay, as described in paragraphs (f)(2)(ii) and (f)(5) of this section. LIS-eligible Part D enrollees are eligible to participate in the program. The requirements described in this paragraph (d) are applicable beginning October 1, 2025, with respect to eligibility and election in the Medicare Prescription Payment Plan for 2026.

(1) Election. A Part D sponsor must allow any Part D enrollee, including those who are LIS-eligible, to opt into the program prior to the beginning of the plan year or at any point during the plan year.

(D) In the event a Part D sponsor fails to process the request within 24 hours due to no fault of the Part D enrollee, the Part D sponsor must—

(1) Process a retroactive election effective on the date on which the enrollee should have been admitted into the program; and

(2) Reimburse the enrollee for any cost-sharing paid on or after that date within 45 calendar days and include those amounts, as appropriate, in the program calculations.

(5) Inclusion of all covered Part D drugs once in the program. Once a participant has opted into the program, cost sharing for all covered Part D drugs must be included in the program.

(6) Retroactive election. (i) A Part D sponsor must have in place a process to effectuate a retroactive election into the Medicare Prescription Payment Plan if both of the following conditions are met:

(A) The Part D enrollee believes that any delay in filling the prescription(s) due to the 24-hour timeframe required to process their request to opt in may seriously jeopardize their life, health, or ability to regain maximum function.

(B) The Part D enrollee requests retroactive election within 72 hours of the date and time the claim(s) were adjudicated.

(ii) The Part D sponsor must process the reimbursement for all cost sharing paid by the enrollee for the prescription and any covered Part D prescription filled between the date of adjudication of the claim and the date that the enrollee's election is effectuated within 45 calendar days of the election date.

When a Part D enrollee switches Part D plans, whether offered by the same or a different Part D sponsor, during the plan year or is reassigned by CMS, the Part D sponsor of the new Part D plan is not permitted to automatically sign up the individual for the Medicare Prescription Payment Plan under the new plan but must allow the individual to opt into the program. Part D plan has the definition established at § 423.4.

(i) The Part D sponsor of the prior Part D plan must offer the participant the option to repay the full outstanding amount in a lump sum.

For each billing period after an individual has opted into the program and incurred out-of-pocket costs, a Part D sponsor must calculate a monthly amount that takes into account the out-of-pocket costs in that month that were incurred on or after the date on which the individual opted into the program.

(i) A Part D sponsor must not bill a participant who is in the program but has not yet incurred any out-of-pocket costs during the plan year.

(ii) While past due balances from prior monthly bills may also be included in a billing statement, which could result in the total amount on the billing statement exceeding the maximum monthly cap, the amount billed for the month for which the maximum monthly cap is being calculated cannot be higher than the cap for that month.

(iii) A Part D sponsor must not charge late fees, interest payments, or other fees, such as for different payment mechanisms.

(A) A Part D sponsor must ensure that—

(1) Any third party it contracts with complies with such requirements.

(2) Participants do not incur any charges or fees as a result of overbilling or overpayment errors made by the Part D sponsor.

(B) [Reserved]

(iv) A Part D sponsor must send a bill for the Medicare Prescription Payment Plan that is separate from the bill for collection of premiums, if applicable.

(2) Billing period. Each billing period will be a calendar month.

(i) The billing period begins on either of the following:

(A) The effective date of a Part D enrollee's participation in the Medicare Prescription Payment Plan (for the first month a participant elects into the program during the plan year).

(B) The first day of the month (for each subsequent month or for the first month of a participant who elects into the program prior to the start of the plan year).

(ii) The billing period ends on the last date of that month.

(3) Billing statement. Billing statements must include all of the following information:

(i) A statement that the bill is for the Medicare Prescription Payment Plan.

(ii) A brief description of the program.

(iii) A reference to where additional information about the program can be found.

(iv) The effective date of program participation.

(v) The last payment received, showing the date, amount of the last payment, and the means of payment made by the participant.

(vi) Any balance carried over from the prior month, including any missed payments.

(vii) Itemized out-of-pocket costs by prescription for the month being billed.

(viii) The amount due from the participant for the month being billed (that is, the amount based on the application of the monthly cap calculation).

(ix) The remaining total out-of-pocket cost sharing balance.

(x) Information on the next steps if the participant fails to pay by the stated due date.

(xi) Information on how to voluntarily opt out of the program and balances due if participation is terminated.

(xii) Information on the dispute processes available if the individual disputes their bill.

(xiii) LIS program information, including the following:

(A) General information about how to enroll in the LIS program (as an additional or alternative avenue for addressing prescription drug costs).

(B) A statement that LIS enrollment, for those who qualify, is likely to be more advantageous than participation in the Medicare Prescription Payment Plan.

(xiv) Plan contact information for participant questions about the billing statement.

(4) Treatment of unsettled balances. Any unsettled balances with respect to amounts owed under the program will be treated as plan losses.

(i) The Secretary is not liable for any such balances outside of those assumed as losses estimated in a Part D sponsor's plan bid.

(ii) If a Part D sponsor is compensated by or on behalf of the participant for an unsettled balance or sells an unsettled balance as a debt, that Part D sponsor cannot treat the amount as a loss and cannot include it in its bid.

(5) Prioritization of premium payments. If a Part D enrollee has opted into the program and makes payments directly to the Part D sponsor, and it is unclear whether a payment should go towards the participant's outstanding Part D plan premium or Medicare Prescription Payment Plan balance, then the payment must be applied to the Part D premium.

(6) Financial reconciliation. A Part D sponsor must have a financial reconciliation process in place to correct inaccuracies in billing or payments or both.

(i) Participant payment. (A) A participant may pay more than the maximum monthly cap, up to the annual out-of-pocket threshold.

(B) The participant cannot pay more than their total OOP costs for the Medicare Prescription Payment Plan.

(C) If a participant does pay more than their total OOP costs for the Medicare Prescription Payment Plan, then the Part D sponsor must reimburse the participant the amount that is paid above the balance owed.

(ii) Reimbursements for excess participant payments. A Part D sponsor must develop standardized procedures for determining and processing reimbursements for excess Medicare Prescription Payment Plan payments made by program participants.

(iii) Claims adjustments resulting in increased amounts owed. When Part D claims adjustments result in increased amounts owed by the participant, and these amounts have not yet been billed to the participant, they must be included in the revised remaining OOP costs owed by the participant (as defined at paragraph (b)(1) of this section) and, thus, in the subsequent month maximum cap for the next billing period.

(h) Participant disputes—(1) Coverage determination and appeals procedures. A Part D sponsor must apply the Part D coverage determination and appeals procedures specified at § 423.566(a) to any disputes made by program participants concerning the cost sharing amount of a covered Part D drug.

(2) Grievance procedures. A Part D sponsor must apply the Part D grievance procedure specified at § 423.562 to any dispute made by a program participant related to any aspect of the Medicare Prescription Payment Plan.

(i) Pharmacy point of sale notification process. (1) When a Part D sponsor is notifying a pharmacy that a Part D enrollee has incurred out-of-pocket costs with respect to covered Part D drugs that make it likely the enrollee may benefit from participating in the program, as required at paragraph (e)(2) of this section, the Part D sponsor must use standard code values for notifying the pharmacy that an enrollee has been identified as likely to benefit, as outlined by the National Council for Prescription Drug Programs.

(2) A Part D sponsor must ensure that the “Medicare Prescription Payment Plan Likely to Benefit Notice” is provided to enrollees identified as likely to benefit (or the person acting on their behalf) through the pharmacy point of sale notification process.

(i) In pharmacy settings in which there is direct contact with enrollees (for example, community pharmacies where enrollees present in person to pick up prescriptions), the Part D sponsor must ensure that a hard copy of the “Medicare Prescription Payment Plan Likely to Benefit Notice” is provided to enrollees identified as likely to benefit (or the person acting on their behalf) at the time the prescription is picked up.

(ii) For non-retail pharmacy settings without in-person encounters (such as mail order pharmacies), a Part D sponsor must require the pharmacy to notify the Part D enrollee via a telephone call or their preferred contact method.

(iii) For long-term care pharmacy settings, the Part D plan sponsor should not require that the pharmacy notify the Part D enrollee prior to dispensing the medication. Instead, the Part D plan sponsor should require the long-term care pharmacy to provide the notice to the Part D enrollee (or their authorized representative) at the time of its typical enrollee cost-sharing billing process.

(iv) If the pharmacy is in contact with a Part D enrollee identified as likely to benefit and the enrollee declines to complete the prescription filling process, the Part D sponsor must ensure that the pharmacy provides the “Medicare Prescription Payment Plan Likely to Benefit Notice” to the Part D enrollee.

(3) A Part D sponsor must ensure that any contract between the Part D sponsor and a pharmacy (or between a first tier, downstream, or related entity and a pharmacy on the Part D sponsor's behalf) for participation in one or more of the Part D sponsor's networks includes a provision requiring pharmacies to provide this notification to Part D enrollees.

(j) Pharmacy claims processing—(1) Electronic claims processing methodology. Part D sponsors must use, and must ensure pharmacies use, a bank identification number (BIN) or processor control number (PCN) electronic claims processing methodology for applicable Medicare Prescription Payment Plan transactions.

(i) Part D sponsors must utilize, and ensure pharmacies utilize, an additional BIN/PCN that is unique to the Medicare Prescription Payment Plan to facilitate electronic processing of supplemental coordination of benefits (COB) transactions for program participants.

(ii) A Part D sponsor must provide the unique Medicare Prescription Payment Plan BIN/PCN and any other pertinent billing information to the pharmacy on paid claim responses when the enrollee is also a Medicare Prescription Payment Plan participant.

(iii) A Part D sponsor must assign a program-specific PCN that starts with “MPPP” and report the new BIN/PCN to CMS.

(iv) The transaction processed through the Medicare Prescription Payment Plan BIN/PCN will be submitted after processing any applicable other payer transactions in order to capture the final patient responsibility amount after all other payers have paid.

(2) Supplemental coverage that increases final patient pay amount. When a Part D enrollee has supplemental coverage that modifies their final out-of-pocket responsibility for covered Part D drugs:

(i) When the final patient pay amount returned to the pharmacy by a supplemental payer for a covered Part D drug is higher than the original Part D patient pay amount, the Part D sponsor may only include in the Medicare Prescription Payment Plan the participant's original Part D cost sharing, as determined by their plan-specific benefit structure.

(ii) [Reserved]

(3) Prescription drug event reporting. A Part D sponsor must ensure that the claims processing methodology described in paragraph (j)(1) of this section has no impact on prescription drug event (PDE) cost/payment field reporting, meaning PDE records must reflect participant and plan liability amounts as if the Medicare Prescription Payment Plan did not apply.

(4) Real-time benefit tools. A Part D sponsor must ensure that participation in the Medicare Prescription Payment Plan or the associated claims processing methodology described in paragraph (j)(1) of this section or both has no impact on the cost-sharing information displayed in real-time benefit tools.

(5) Inclusion of retroactive claims. A Part D sponsor is not required to retroactively include under this program claims submitted to the Part D sponsor by a Medicare Prescription Payment Plan participant (whether the request is made via paper form, telephonically, or electronically) except as provided in paragraph (d)(6) of this section.

(6) Re-adjudication of prescription drug claims for new program participants. (i) When a Part D enrollee receives the “Medicare Prescription Payment Plan Likely to Benefit Notice” from the pharmacy, they may choose to take time to consider opting into the program and leave the pharmacy without the prescription that triggered the notification.

(ii) When the Part D enrollee returns to the pharmacy after their election into the Medicare Prescription Payment Plan has been effectuated, the plan sponsor must require the pharmacy to reverse and reprocess the high-cost claim that triggered the likely to benefit notification.

(A) Should a Part D enrollee have other unpaid claims at the same pharmacy for covered Part D drugs from prior dates of service, in addition to the prescription that may have triggered the likely to benefit notification, they may also request that those claims be readjudicated.

(B) [Reserved]

(iii) When the Part D claim date of service is the same as the date of program effectuation), the Part D sponsor is not required to ensure the pharmacy reverse and resubmit the Part D claim, provided that they otherwise obtain the necessary Medicare Prescription Payment Plan BIN/PCN for the program-specific transaction.

(k) Pharmacy payment obligations. A Part D sponsor must ensure that enrollee participation in the Medicare Prescription Payment Plan does not affect the amount paid to pharmacies or the timing of such payments, consistent with § 423.520. A Part D sponsor must not do either of the following:

(1) Impose any fees or costs related to program implementation on pharmacies.

(2) Hold pharmacies responsible for any unsettled balances of a participant or for collecting unpaid balances from the participant on the Part D sponsor's behalf.

(l) [Reserved]

(m) General Part D sponsor outreach and education requirements. The requirements described in this paragraph (m) are applicable beginning October 1, 2025, with respect to general outreach for the Medicare Prescription Payment Plan for 2026.

(1) Mailing. A Part D sponsor, except a dual eligible special needs plan (D-SNP), must provide a Medicare Prescription Payment Plan election request form, described at paragraph (d)(10)(i) of this section, and additional educational information on the program in a hard copy mailing.

(i) The mailing must be sent by the later of—

(A) Within 10 calendar days from receipt of CMS confirmation of enrollment in the Part D plan; or

(B) The last day of the month prior to the plan effective date.

(ii) The election request form and supplemental information may be sent—

(A) With the membership ID card mailing described at § 423.2267(e)(32); or

(B) In its own envelope.

(iii) The mailing may be sent only to a Part D enrollee who is receiving a new membership ID card or to all Part D enrollees.

(iv) The additional information requirement may be fulfilled by including in the mailing the CMS-developed fact sheet about the program. If the Part D sponsor develops and uses alternative informational materials in lieu of the CMS-developed fact sheet to satisfy this paragraph (m)(1)(iv), they must ensure that these alternative materials accurately convey program information and are compliant with existing Part D requirements specified at subpart V of this part.

(2) Websites. In addition to meeting requirements described at §§ 423.128(d)(2) and 423.2265(b), a Part D sponsor is required to include all of the following on its website:

(i) An election request mechanism, as described at paragraph (d)(2) of this section.

(ii) An overview of the Medicare Prescription Payment Plan.

(iii) Examples of the program calculation and explanations.

(iv) A description of Part D enrollees who may be likely to benefit from the program.

(v) The financial implications of participation.
