What is the Medicare Prescription Payment Plan?

How does the Medicare Prescription Payment Plan work?

It's a payment option that works with your current drug coverage. When you fill a prescription for a drug covered by Part D, you don't pay the pharmacy (including mail order and specialty pharmacies). Your plan tells the pharmacy you're participating, and each month it sends you a bill with the amount you owe for your prescriptions, when it's due and how to pay.

You're still responsible for the costs. If you want to know what a drug will cost before you take it home, call your plan or ask the pharmacist. You also keep paying your plan premium each month, if you have one, on a separate bill.

How is the monthly bill calculated?

All plans use the same formula. Each monthly bill is what you would have paid for any prescriptions you got, plus your previous month's balance, divided by the number of months left in the year. Your first month's bill works differently: it's the lower of your out-of-pocket costs that month or a 'maximum possible payment', which is the $2,100 yearly out-of-pocket maximum (2026) minus what you've already paid out of pocket that year, divided by the months left.

Your payments might change every month, so you might not know your exact bill ahead of time. Payments can go up when you fill a new prescription or a refill, because new costs are added while fewer months are left to spread them over. In a calendar year, you'll never pay more than the total you would have paid the pharmacy without the payment option, or the out-of-pocket maximum for drugs your plan covers ($2,100 in 2026). That cap applies to everyone with Medicare drug coverage, whether or not they use the payment option, and in 2027 the out-of-pocket cap for covered Part D drugs is $2,400.

Who does the Medicare Prescription Payment Plan help?

You're most likely to benefit if you have high drug costs earlier in the calendar year. You can start any time in the year, but starting earlier (like before September) gives you more months to spread out your costs. Medicare.gov says the payment option may not be the right choice for you if:

• Your yearly drug costs are low.
• Your drug costs are the same each month.
• You're considering signing up late in the calendar year (after September).
• You don't want to change how you pay for your drugs.
• You get or are eligible for Extra Help from Medicare, or a Medicare Savings Program.
• You get help paying for your drugs from other organizations, like a State Pharmaceutical Assistance Program, a coupon program or other health coverage.

How do I sign up, and does it renew each year?

Visit your health or drug plan's website, or call your plan, to start participating. After the plan reviews your request, it sends you a letter confirming your participation and explaining how to pay your bill.

If you're participating and stay in the same Part D plan, your participation is automatically renewed for 2027. If you leave your plan or change to a new Medicare drug plan or Medicare health plan with drug coverage, your participation ends, and you contact the new plan if you want to participate again. See Can I change my Medicare plan, and when?.

What happens if I miss a payment or want to leave?

If you miss a payment, your plan sends you a reminder. If you don't pay by the date in that reminder, you're removed from the Medicare Prescription Payment Plan but stay enrolled in your Medicare health or drug plan. You still owe the amount due, with no interest or fees even if your payment is late, and you can pay it all at once or be billed monthly. Medicare.gov advises always paying your plan's monthly premium first, so you don't lose your drug coverage.

You can leave at any time by contacting your plan; leaving doesn't affect your Medicare drug coverage or other Medicare benefits. You still pay any balance you owe, and you pay the pharmacy directly for new drug costs. If you think your plan made a mistake on a bill, call the plan; you have the right to use the grievance process in your Member Handbook or Evidence of Coverage.
