If Medicare doesn't cover your prescription drug(s), then you have the option to switch to a different drug performing similar functions.
Talk with a doctor
Talk with your doctor or other health care provider to decide what to do if or when your prescription runs out. Perhaps there is a different drug covered by the plan that might work just as well for you.
Call Customer Service
Call Customer Service at the number on your membership card for a list of covered drugs that treat the same medical condition. This list can help your doctor find a covered drug that might work for you.
