Many older Americans cut pills in half or skip doses to make a prescription last. If that is you, please read this before your next refill.
In 2026, Medicare drug coverage caps what you pay for covered prescriptions at $2,100 for the year. After that, covered drugs cost you nothing until January — and you can spread even that $2,100 into monthly payments.
Cutting or skipping doses can make a medicine stop working properly. If cost is the reason, one of the options below may fix it — and talk to your doctor or pharmacist before changing how you take anything.
How the $2,100 cap works
According to the Centers for Medicare & Medicaid Services , in 2026:
- You generally pay 25 percent coinsurance on covered generic and brand-name drugs until you reach the cap, depending on your plan.
- Once your out-of-pocket spending on covered drugs reaches $2,100, you pay $0 for covered drugs for the rest of the year.
- The cap resets every January and is adjusted for inflation. It was $2,000 in 2025.
It applies to stand-alone Medicare drug plans (Part D) and to Medicare Advantage plans that include drug coverage.
Spread the cost out: the Medicare Prescription Payment Plan
The cap stops the total from getting out of hand. But a big bill at the pharmacy counter in February can still be impossible on a fixed income.
Every Medicare drug plan must offer the Medicare Prescription Payment Plan . Instead of paying at the counter, you get a capped monthly bill that spreads your costs across the rest of the year.
Be clear about what it does and does not do:
- It does not lower your total cost. It only spreads it out.
- It helps most early in the year, when there are more months left to spread costs over.
- To join, call the number on your drug plan card.
Pay even less: Extra Help
If your income and savings are limited, Extra Help can lower your premium, deductible and copays much further — often to a few dollars per prescription. Many people who qualify never apply. If you already get Medicaid or a Medicare Savings Program, you may get it automatically. Our guide explains both.
Make sure your drugs are actually covered
The cap only counts drugs on your plan’s list of covered drugs (its formulary). Plans can change that list every year. Check your medicines during Medicare Open Enrollment, October 15 to December 7, when you can switch plans for next year. A free SHIP counsellor at shiphelp.org can do the comparison with you.
Our free benefits check shows whether you may qualify for Extra Help in about five minutes.
Frequently Asked Questions
Is there a cap on Medicare prescription drug costs in 2026?
Yes. In 2026, once your out-of-pocket spending on covered Part D drugs reaches $2,100, you pay nothing more for covered drugs for the rest of the calendar year. Before you reach the cap you generally pay 25 percent coinsurance for covered generic and brand-name drugs, depending on your plan. The cap was $2,000 in 2025 and is adjusted each year for inflation. It applies to stand-alone Medicare drug plans and to Medicare Advantage plans that include drug coverage.
What is the Medicare Prescription Payment Plan?
It is an option that every Medicare drug plan must offer. Instead of paying large amounts at the pharmacy counter, you pay your out-of-pocket drug costs in capped monthly bills spread over the rest of the year. It does not lower the total you pay — it only spreads it out. It helps most if you have high drug costs early in the year, because there are more months left to spread them over. Call your drug plan to sign up.
Can I get help paying even less than the cap?
Yes, if your income and savings are limited. Extra Help, also called the Low-Income Subsidy, lowers your drug plan premium, deductible and copays, often to just a few dollars per prescription. Many people who qualify never apply. You can apply through Social Security, and if you qualify for Medicaid or a Medicare Savings Program you may get Extra Help automatically.
Does the cap cover every medication?
It covers drugs on your plan’s formulary — its list of covered drugs. Spending on drugs your plan does not cover generally does not count toward the cap. That is why it matters to check that your medications are on your plan’s list, especially during Medicare Open Enrollment from October 15 to December 7, when you can switch plans for the next year.
