Part D (prescription drug) plans

Medicare Part D helps with the cost of prescription drug coverage.

Medicare prescription drug plans are offered by Medicare-approved private insurance companies and cover your prescription drug costs for covered medications.

Coverage and costs beyond the standards set by Medicare can vary and your choices may vary depending on where you live. Some plans have pharmacy networks and mail order pharmacies offering discounted pricing.

To be eligible for a Part D plan, you must be enrolled in Part A or Part B (Original Medicare).

You can choose to receive Part D coverage in addition to:

  • Part A and/or Part B
  • Part A and Part B with a Medicare Supplement insurance plan
  • Medicare Advantage Plan (Part C) generally includes Part D

What is covered?

  • Specific brand name and generic drugs on the formulary (a list of specific drugs covered)
  • Types of drugs commonly prescribed according to federal standards
  • Commercially available vaccines not covered by Part B

Plan costs for 2024


  • Plan premiums vary and can change each year
  • You may pay a premium penalty if you enrolled late in Part D


  • The 2024 maximum deductible is $545
  • Some plans may not have a deductible
  • Some plans may have tiers with separate deductibles


  • Some plans may have fixed copay amounts each time you fill a prescription


  • Some plans require you pay a coinsurance percentage every time you fill a prescription

When to enroll in a Part D plan
