Before you start looking at plans:

  • Make a list of the medicines you take and how much you currently pay for them. You may want to ask your doctor for help.
  • Make note of pharmacies you use regularly.

There are two types of drug plans you can choose from depending on how you get your Medicare benefits. If you have:

  • Original Medicare: Choose a stand-alone prescription drug plan (PDP) if you want to continue to receive your other health benefits through Original Medicare.
  • Medicare Advantage Plan (such as an HMO or PPO): Generally, you must get Part D drug coverage as part of your Medicare Advantage Plan’s benefits package. (If you join a Medicare Medical Savings Account (MSA), Private Fee-for-Service (PFFS) plan without drug coverage, or a Cost Plan, you can also join a PDP.)

Get the facts before you enroll in a plan. Below are some questions to ask.

Covered drugs:

  • Does the plan cover all the medications I am taking?
  • If the plan does not cover a medication I take, does it cover one that will work for me? (Ask your doctor.)
  • Does the plan require that I get special permission before it will cover the medication I need (such as prior authorization or step therapy)?


  • How much will I pay at the pharmacy (copayments or coinsurance) for each drug I need? (Certain drugs may have high coinsurance.)
  • If a drug I take has a very high coinsurance, is there a drug I can take that will cost me less? (Ask your doctor.)
  • How much will I pay for monthly premiums and the annual deductible?

Pharmacy network:

  • Can I fill my prescriptions at the pharmacies I use regularly?
  • Can I fill my prescriptions when I travel?
  • What happens if I go to pharmacies that are not in the network?
  • Can I get prescriptions by mail order?

Coordinating with your other benefits:

  • Will the Medicare drug plan I am considering work with other coverage I have?
