Medicare Prescription Payment Plan
Spread your out-of-pocket drug costs into predictable monthly payments — instead of paying large amounts at the pharmacy.
What is the M3P?
The Medicare Prescription Payment Plan (sometimes called M3P or MPPP) is a voluntary payment option that lets you spread your out-of-pocket prescription drug costs over the plan year in monthly installments. Instead of paying a large copay or coinsurance at the pharmacy, you pay a smoothed monthly amount.
This program does not lower your total costs — it simply changes when you pay them, making your expenses more predictable and manageable.
Who can use it?
Anyone enrolled in a Medicare Part D plan can opt in to the Payment Plan, regardless of income level. It's available through both standalone Part D plans and Medicare Advantage drug plans.
What's new for 2026
If you participated in the Payment Plan in 2025, you are automatically re-enrolled for 2026 unless you choose to opt out. If you switch to a different Part D plan for 2026, you'll need to opt in again with your new plan.
How to opt in
Contact your Part D plan directly to enroll in the Medicare Prescription Payment Plan. You can also find information about the program at Medicare.gov and in your "Medicare & You" handbook.
