Medicare Prescription Drug Coverage Benefits (Part D)


Medicare prescription drug coverage (Part D) is available to everyone with Medicare. To get Medicare drug coverage, you must join a Medicare drug plan. Plans vary in cost and drugs covered.

Two types of plans offer Medicare prescription drug coverage:

  1. Medicare Prescription Drug Plans. These plans (sometimes called “PDPs”) add drug coverage to Original Medicare, some Medicare Cost Plans, some Medicare Private Fee-for-Service (PFFS) Plans, and Medicare Medical Savings Account (MSA) Plans. 
  2. Medicare Advantage Plans (like an HMO or PPO) or other Medicare health plans that offer Medicare prescription drug coverage. You get all of your Part A and Part B coverage, and prescription drug coverage (Part D), through these plans. Medicare Advantage Plans with prescription drug coverage are sometimes called “MA-PDs.”

Who Can Get Medicare Drug Coverage?

To join a Medicare Prescription Drug Plan, you must have Medicare Part A and/or Part B. To get prescription drug coverage through a Medicare Advantage Plan, you must have Part A and Part B.
