What is Medicare Part D?
Part D is prescription drug coverage. You have to get Medicare Part D through a private insurance company. Different insurers offer different types of plans, so your cost for the plan (premium) and your out-of-pocket expenses for prescription drugs (copays, coinsurance and deductible) will vary.
Another difference from plan to plan is which drugs are covered. Some drugs (for example brand name drugs vs. generic drugs) are covered at different levels. The insurer will publish a prescription drug formulary that lists this information.
Who can get Medicare Part D Coverage?
A person must have Part A and/or Part B to enroll in Part D or it is offered as part of a Medicare Advantage plan (Part C). You must live in the service area for the particular Medicare prescription drug plan that you are considering.
