How can I find out which Part D drug plans cover the prescription drugs I take?

En español | Ideally, the best way to pick a Part D drug plan is according to the specific prescription drugs you take. That’s because no Part D plan covers all drugs, and the plans charge widely varying copays, even for the same drug. The Medicare plan finder program aims to make this comparison easier for you. 

If you go to and enter your zip code, the names of the drugs you take, plus their dosage and how often you take them, the plan finder does the math to identify the plan that covers your drugs at the lowest out-of-pocket cost.

Alternatively, you can call Medicare’s help line at 800-633-4227 and ask a customer service representative to make the same search for you. You’ll need to provide the exact name of your drug(s), plus the dosage and quantity you take. (For example: 20 milligrams, two pills per day.) The rep can have the results mailed to you, at no charge.

Or you can contact your state health insurance assistance program (SHIP), which provides personal help from trained counselors on all Medicare and Medicaid issues — free of charge. Counselors are experienced in using the Medicare plan finder to help people find the Part D plan that best meets their needs and preferences. To find the main toll-free number of your SHIP (which goes by different names in some states), go to and select your state.
