Part D Prescription Drug Plans

Medicare Part D helps cover the cost of prescription drugs. It is offered by private companies and you choose either a stand-alone plan or drug coverage that comes inside a Medicare Advantage plan.

What this page covers

  • Compare stand-alone drug plans (PDP) or integrated MA-PD plans.
  • Formulary-based pricing on covered prescriptions.

Two ways to get drug coverage

  • Stand-alone drug plan (PDP): added to Original Medicare, often alongside a Medigap policy.
  • Medicare Advantage with drug coverage (MA-PD): drug coverage is part of one plan that also covers Parts A and B.

Terms you will see

  • Formulary: the list of drugs a plan covers, sorted into tiers. The tier decides what you pay.
  • Deductible, copay and coinsurance: how your share of the cost is set.
  • Annual out-of-pocket cap: Part D has a yearly limit on what you pay for covered drugs. For plan year 2027 the yearly cap is $2,400, the standard deductible is $700, and insulin is capped at $35 for a one-month supply.
  • Late enrollment penalty: if you go without creditable drug coverage for a period after you first qualify, your monthly premium can be higher. We explain how it is calculated.
  • Extra Help: a federal program that can lower drug costs for people with limited income and resources. We can point you to how to apply.

Before you choose, check

  • That your current medications are on the formulary.
  • The pharmacies you use, and whether they are in the plan's network.
  • Any rules such as prior authorization or step therapy.

Questions people ask

  • Is it required? Not everyone must enroll, but going without coverage can lead to a penalty later.
  • Can I change? Yes, during certain enrollment periods. We explain the dates.
