What questions should I ask of a Part D prescription drug plan?

Medicare Part D, the prescription drug benefit, is the part of Medicare that covers most outpatient prescription drugs. Part D is offered through private companies either as a stand-alone prescription drug plan (PDP), for those enrolled in Original Medicare, or a set of benefits included with your Medicare Advantage Plan.

You should make sure to find a Part D plan that meets your specific health care needs. Before you start looking at plans, gather a list of the prescriptions you take, including their dosages and usual costs, and the pharmacies you regularly use.

Here are some questions you should ask before choosing a Part D plan:

Drug coverage

  • Are my prescriptions on the plan’s formulary?
    • The formulary is the list of prescription drugs for which a Part D plan will help pay.
  • Does the plan impose any coverage restrictions, such as prior authorization, step therapy, or quantity limits?
    • Prior authorization means that you must get approval from your Part D plan before the plan will pay for the drug.  
    • Step therapy means that your plan requires you to try a cheaper version of your drug before it will cover the more expensive one.
    • Quantity limits restrict the quantity of a drug you can get per prescription fill, such as 30 pills of Drug X per month.
  • If the plan does not cover a medication I take, does it cover one that will work for me? (Ask your doctor.)

Costs

  • How much will I pay at the pharmacy (copayments or coinsurance) for each drug I need?
  • How much will I pay for monthly premiums and the annual deductible?
  • How much will I have to pay for brand-name drugs? How much for generic drugs?
  • What will I pay for my drugs during the coverage gap?
  • If a drug I take has a high coinsurance, is there a drug I can take that will cost less? (Ask your doctor.)
  • Am I eligible for Extra Help or a State Pharmaceutical Assistance Program (SPAP)?

Pharmacy network

  • What is the service area for the plan?
  • Can I fill my prescriptions at the pharmacies I use regularly?
  • Can I fill my prescriptions when I travel?
  • What will my coverage options and costs be if I visit out-of-network pharmacies?
  • Can I get prescriptions by mail order?

Coordination with other insurance

  • Will Part D work with other coverage I have to lower my costs?
  • Do I need to enroll in Part D if I have other creditable coverage?
  • Do I need to enroll in Part D if I have job-based drug coverage?

There is no one best Part D plan for everyone. Instead, you should ask questions and make sure to find a Part D plan that meets your specific health care needs.
