Which Drugs Does Medicare Cover? 
Medicare Part B covers some medications . Mostly , these are medications that are provided by and administered in the doctor 's office . It also pays for transplant medications that are acquired through pharmacies . Other than those , all medications fall under Part C -LRB- Medicare Advantage -RRB- or Part D -LRB- Prescription Drug Plan -RRB- . There are many plans to choose from , and they do n't all cover the same medications or have the same copays , so it is important to look at the plan formulary before deciding on your insurance .
