Medicare pays for almost all of the cost of your covered drugs if you join a
Medicare Prescription Drug Plan (Part D) or a
Medicare Advantage Plan with Medicare prescription drug coverage. In most cases, you will pay only a small amount out-of-pocket for each covered prescription. Your costs and the drugs that are covered vary by plan.
If you have Medicare and full coverage from Medicaid, and you live in certain
Institutions (like a nursing home), you will pay nothing for your covered prescription drugs.
