What Medicare Part D Plans Cover

Medicare Part D plans offer prescription drug coverage. Each plan has a formulary, which is the plan’s list of covered drugs. Typically, Part D plans have drug tiers, which indicate the drug’s cost.

Part D Formularies

A Medicare Part D formulary is a list of all the drugs covered by the plan. All Medicare Part D plans are required to cover a wide range of prescription drugs for people with Medicare, with at least two drugs per drug category.

Medicare Part D Formulary Coverage
Drugs Part D plans must cover Drugs in these protected classes:
  • Anticonvulsants
  • Antidepressants
  • Antineoplastics (cancer drugs)
  • Antipsychotics
  • Antiretrovirals (HIV/AIDS drugs)
  • Immunosuppressants
Commercially available vaccines
Generic and brand-name drugs in commonly prescribed categories (such as antibiotics, insulin, and drugs for pain)
Drugs not covered by Part D plans Drugs you don’t self-administer which are covered by Medicare Part B, such as those in an outpatient hospital setting
Cosmetic medications
Cough and cold medications
Over-the-counter drugs
Prescription vitamins or minerals
Weight gain or loss medications
Erectile dysfunction drugs

If your specific drug is not on a plan’s formulary, it should have a similar drug available. You can ask for an exception if you need a drug that’s not on a plan’s formulary.

Part D Tiers

Usually, Medicare Part D plans categorize drugs in tiers, with each tier charging a different copayment amount. For example:

Medicare Part D Tiers
Tier Cost What’s covered
Tier 1 Lowest copayment Most generic prescription drugs
Tier 2 Moderate copayment Preferred brand-name prescription drugs
Tier 3 High copayment Non-preferred brand-name prescription drugs
Tier 4 or 5 (specialty tier) Very high copayment High-cost prescription drugs

Medicare Part D Plan Eligibility and Enrollment

You can enroll in a Medicare Part D prescription drug plan if you’re enrolled in Medicare Part A and/or Part B, or a Medicare Advantage Private Fee-for-Service (PFFS) Plan that doesn’t offer prescription drug coverage. You must be enrolled in Medicare Part A and B to join a Medicare Advantage Plan.

It pays to enroll in prescription drug coverage during your initial enrollment period, even if you don’t take prescription medications. If you don’t enroll during this period and have no creditable drug coverage, you’ll have a 1% penalty for each month you don’t enroll, which will be added to your Part D monthly premium.

Part D enrollment is available during specific enrollment periods:

Medicare Part D Enrollment Periods
Enrollment period When it happens What you can do
Initial Enrollment Period The seven-month period beginning three months before you turn 65 and three months after New enrollment
Annual Enrollment Period October 15 to December Enroll in a new plan, disenroll, or make a one-time switch from one plan to another.
Medicare Advantage Open Enrollment January 1 to March 31 Switch to a different Medicare Advantage Plan with or without drug coverage. Go back to Original Medicare and enroll in a Part D plan.

There are multiple ways to enroll in Medicare Part D prescription drug plans:

  • Enroll on the Medicare Plan Finder or on the plan’s website.
  • Complete a paper enrollment form.

The initial coverage phase starts when you meet your deductible and ends when you and your plan have spent $4,660. You then enter into the coverage gap phase (also known as the “donut hole”) until your out-of-pocket spending reaches $7,400. You pay a small amount for prescription drugs for the remainder of the year while you are in the catastrophic coverage phase.

If you have limited resources, you may be able to get financial assistance through Medicaid, Extra Help, or Pharmaceutical Assistance Programs in your state.

How to Choose a Medicare Part D Plan in South Dakota

Consider these factors as you compare Medicare prescription drug plans available in your area:
Monthly premium You’ll pay this amount every month whether or not you use your benefits. You should have access to at least one low-cost plan in your area.
Additional costs How much will it cost to use your benefits? Understand your deductible, copayments, and coverage during the gap and catastrophic phases.
Provider network Check to make sure your preferred pharmacies are in network to keep costs as low as possible.
Drug coverage/formulary See if your drugs are on the plan’s formulary and how much they cost each time you fill a prescription. You may want to talk with your doctor about a generic or alternative version of a drug you need.
Plan ratings Consider the quality of the plan based on Medicare star ratings, ratings from independent organizations such as the NCQA (which rates Medicare Advantage Plans that typically include drug coverage), and reviews from plan members.
