Medicare Part D (prescription drug plans) will provide your with insurance, which will cover medications just like other types of medical insurance.
Medicare Part D coverage can be provided by a “stand-alone” or Medicare Advantage plan, which includes medication coverage (or an MA-PD, which includes prescription drug and Medicare health coverage).
If you enroll in Medicare Part D coverage, you will pay monthly premiums, which range form a few dollars up to over 100 dollars. If you enroll in the Medicare Advantage plan, your monthly premium will be zero. Monthly premiums will vary and will depend on the benefits of your selected Medicare Advantage or Medicare Part D plan, and the state you live in.
