What Are Medicare Part B Drugs? 
Medicare Part B medications are usually provided and given by someone in the doctors office as part of a treatment . There are a couple of exceptions that may be picked up at a local drug store . These include medications to be used in a nebulizer , medications to prevent rejection of a transplanted organ , and diabetic testing supplies . If your doctor wants you to pick any of these up , make sure that the prescription is written following CMS directions or the pharmacy will not be able to bill Medicare . This includes having the diagnosis code written on the prescription , exact quantities and frequency of use , and your name , date of birth , and address written on the prescription .
