Medicare Prescription Plans

How to get Prescription Drug Coverage

  • Medicare Prescription Drug Plan (Part D). These plans (sometimes called “PDPs”) add drug coverage to Original Medicare, some Medicare Cost Plans, some Medicare Private Fee-for-Service (PFFS) Plans, and Medicare Medical Savings Account (MSA) Plans.
  • Medicare Advantage Plan (Part C) (like an HMO or PPO) or other Medicare health plan that offers Medicare prescription drug coverage. You get all of your Medicare Part A (Hospital Insurance) and Medicare Part B (Medical Insurance) coverage, and prescription drug coverage (Part D), through these plans. Medicare Advantage Plans with prescription drug coverage are sometimes called “MA-PDs.” You must have Part A and Part B to join a Medicare Advantage Plan.
  • When Purchasing a Medicare Supplement Plan (sometimes called “Medigap”) if you want Prescription Drug coverage you must purchase a Stand alone Prescription Drug Plan.

What Prescriptions Drug Plans Cover

Each Medicare Prescription Drug Plan has its own list of covered drugs (called a formulary). Many Medicare drug plans place drugs into different “tiers” on their formularies. Drugs in each tier have a different cost.

A drug in a lower tier will generally cost you less than a drug in a higher tier. In some cases, if your drug is on a higher tier and your prescriber thinks you need that drug instead of a similar drug on a lower tier, you or your prescriber can ask your plan for an exception to get a lower copayment.

A Medicare drug plan can make some changes to its formulary during the year within guidelines set by Medicare. If the change involves a drug you’re currently taking, your plan must do one of these:

Provide written notice to you at least 60 days prior to the date the change becomes effective.

At the time you request a refill, provide written notice of the change and a 60-day supply of the drug under the same plan rules as before the change

Joining a Medicare drug plan may affect your Medicare Advantage Plan

If your Medicare Advantage Plan (Part C) includes prescription drug coverage and you join a Medicare Prescription Drug Plan (Part D), you’ll be disenrolled from your Medicare Advantage Plan and returned to Original Medicare.
