Medicare Prescription Drug Coverage (Part D)
Federal
Medicare Part D (prescription drug coverage) is a Medicare program that helps pay for your prescription medicines. This program pays for some, but not all, of your drug costs.
About this program
Medicare Part D is the part of Medicare that covers prescription drugs. It helps pay for the medicines your doctor prescribes to help you stay healthy.
You can get Part D through a private insurance plan approved by Medicare. You may pay a monthly premium, and you may also pay part of the cost when you pick up your medicine.
You have 2 options when choosing a Medicare Part D plan:
- **Standalone Part D plans:** These plans add drug coverage to original Medicare (Parts A and B). For example, if you have original Medicare with or without a Medicare Supplement (Medigap), you need to add a Part D plan to get help paying for your prescription medicine.
- **Medicare Advantage plans:** You can join a Medicare Advantage (Part C) plan that includes Part A, Part B, and Part D all in one plan.
## Can I get help from Medicare Part D?
You can get Medicare Part D if you already have Part A or Part B. Most people get Part D when they first become eligible for Medicare, usually at age 65. You can also get this coverage if you are younger but have a disability and get Medicare benefits.
## Do I have to join a Medicare Part D plan?
You do not have to join a Medicare Part D plan. But if you decide later that you want Part D after the timeframe for signing up has passed, you will pay extra for the plan each month. This is called the Part D late enrollment penalty.
## How much does Medicare Part D cost?
The cost of Medicare Part D depends on the plan you choose. Most people pay a monthly premium, which averages $34.50 in 2026. If you have a higher income, you might pay an extra amount each month.
You may also pay a deductible (the amount you pay before plan coverage starts) and copays (a small amount for each prescription). The Part D annual deductible in 2026 is $615.
Medicare Part D sets a limit on how much you pay for medicines out of your own pocket every year. In 2026, this limit is $2,100. Once you spend this amount, you will pay nothing for covered medicines for the rest of the year.
If you have limited income, you may qualify for the Part D [Extra Help](https://benefitscheckup.org/program/rxgov_fd_medicare_lis) benefit, which can help lower your prescription drug costs.
## When can I get Medicare Part D?
You can sign up for Part D:
- When you first get Medicare (usually around your 65th birthday). This is called your Initial Enrollment Period. It lasts 7 months, including 3 months before, the month of, and 3 months after your birthday month.
- Each year during Open Enrollment: From Oct. 15 to Dec. 7, you can join, switch, or drop a Part D plan. Your changes start Jan. 1.
You may also qualify for a Special Enrollment Period if you move or lose other drug coverage.
