What it does
If you have Medicare drug coverage, you can ask your Part D plan (or Medicare Advantage plan with drug coverage) to bill remaining covered out-of-pocket drug costs monthly instead of all at once at the pharmacy. People who start an expensive covered medication in January often look at this option. People who wait until November have fewer months left to spread.
What it does not do
It is not a discount, Extra Help, or a cap. The 2026 Part D yearly out-of-pocket threshold is $2,100 for covered Part D drugs. Monthly premiums generally do not count toward that threshold. Drugs the plan does not cover may not count either. Spreading payments does not change those rules.
How a sketch works
Take what may remain under the cap and divide by the months left in the year, including the month you start. January has 12 months; December has 1. The worksheet on this site does that math with the 2026 $2,100 figure. Your plan’s true-out-of-pocket rules still control what counts.
How to opt in
Ask your Part D plan. Medicare.gov also explains the Prescription Payment Plan. Opting in is optional. You can usually opt out. Confirm with the plan — this website cannot enroll you.
Common questions
- Does spreading payments make drugs cheaper?
- No. It changes when you pay, not how much you owe for the year for covered Part D drugs.
- Is this Extra Help?
- No. Extra Help is a separate Social Security program that can lower premiums and copays. You can look at both.
