There are four basic parts of Medicare: A, B, C, and D. Each part helps pay for certain medical services.  

Medicare Part D is health care coverage that helps you pay for the prescription drugs you use.

Here are 5 things to know about Part D – Prescription Drug Coverage:

  1. Original Medicare (Parts A & B) does not cover most prescription drugs.  Beneficiaries must elect and buy this coverage in addition to Part A and/or Part B.
  2. Everyone who qualifies for Medicare and enrolls in either Part A and/or Part B is eligible for Part D Prescription Drug Coverage.
  3. Part D is only offered through private companies that contract with Medicare. You have two choices:
    • Stand Alone Prescription Drug Plans (PDPs)
    • Available through Medicare Advantage Plans (MAPDs)
  4. Part D covers most outpatient drugs you get from the pharmacy or through mail order.  There are exceptions (eg. administered by a doctor, chemotherapy) that are covered under the other parts of Medicare.
  5. There are four stages of Prescription Drug Coverage:
    • Annual Deductible
    • Initial Coverage
    • Coverage Gap
    • Catastrophic Coverage

With Part D Prescription Drug Plans (PDP), coverage and costs vary by plan and may change each year.
