Part D is prescription drug coverage provided by private insurers. If you are receiving your Medicare benefits through Original Medicare, you can get Part D drug coverage through a separate prescription drug plan (PDP). You will be responsible to pay a monthly premium for the plan, as well as a deductible and copays for your prescriptions. If you are receiving your Medicare benefits through a Medicare Advantage plan, you must get your prescription drug coverage through that plan. You will be responsible to pay a deductible and copays for your prescriptions.
