What is Medicare Prescription Drug Coverage?

Medicare Part D is the government's prescription drug benefit, created by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. The Medicare program offers prescription drug coverage to all individuals with Medicare.

A Medicare beneficiary can get prescription drug coverage through one of two options:

  1. Medicare Part D Prescription Drug Plans, also known as "PDPs", are stand-alone prescription drug plans that are approved by Medicare and offered by a private insurance company. Medicare beneficiaries can sign up for Medicare Part D plans to add drug coverage to their Original Medicare coverage, Medicare Supplement (or Medigap) plan, or certain Medicare Advantage plans, including Cost Plans, Private Fee-for-Service (PFFS) plans, and Medical Saving Account (MSA) plans. Anyone enrolled in either Medicare Part A or Medicare Part B is eligible to enroll in a Medicare Part D plan.
  2. Medicare Advantage Prescription Drug Plans, also known as "MAPDs", are Medicare Advantage health plans that offer prescription drug coverage. A Medicare beneficiary can access the same Part D drug coverage by signing up for MAPDs that offer both health and drug coverage. To enroll in this type of plan, you need to be enrolled in both Medicare Part A and Part B.

In either scenario, a Medicare beneficiary would be required to pay the monthly premium charged by the plan and these premiums vary by insurance provider.

Compare Medicare Part D Plans

Each Medicare Part D drug plan has its own list of covered prescription drugs called a "formulary." Medicare requires all Part D prescription drug plan options to cover at least two or more medications within each therapeutic category (e.g. antidepressant, antibiotic). Medicare specifically excludes Part D plans from covering over-the-counter drugs and medications treating fertility, hair growth, and some other conditions.

Since each Medicare Part D plan can cover different drugs, it is essential to evaluate all available Medicare Part D plans in your area to determine:

  • If your drugs are covered
  • What are the estimated out-of-pocket expenses you should expect to pay during the year for your drugs and plan premiums
  • If there are any limitations placed on your drugs (e.g. monthly quantity limits, prior authorization)
