How to ask Part D for an exception

Denise Ramirez, Coverage Editor · Updated August 2026

If your Part D plan does not list the drug, or lists it behind a requirement you cannot meet, the route is a formulary exception. It is a specific request with a specific name; asking generally for coverage will not start it.

Only Medicare Part D works this way. If you have commercial or employer coverage, use the internal appeal route instead.

  1. Ask your prescriber for a supporting statement

    The request does not proceed without it. Your prescriber must state why the formulary alternatives are not appropriate for you.

  2. Name what you are asking for

    Say whether you want a drug added that is not on the formulary, or a utilization requirement waived, such as step therapy, prior authorization or a quantity limit.

  3. Expect a decision in 72 hours, or 24 if expedited

    The clock starts when the plan receives your prescriber's supporting statement, not when you first called.

  4. If refused, file a redetermination within 60 days

    Sixty calendar days from receiving the written coverage determination. Receipt is presumed five days after the date on the notice.

  5. Then the independent review entity, within 60 more days

    If the plan misses its own deadline, the case moves to the independent reviewer automatically within 24 hours.

What to say on the phone

I am requesting a formulary exception for [drug name] under my Part D plan. My prescriber is submitting a supporting statement. Please confirm the fax number or portal for that statement, and tell me the date the 72-hour clock starts.

Ask for the reference number for the coverage determination request and keep it. Every later deadline is measured from that decision.

What each deadline rests on

Every number above comes from one of these. If a deadline here decides something for you, read the source, not our summary of it.

A formulary exception is used to obtain a Part D drug that is not on the plan's formulary, or to have a utilization management requirement such as step therapy, prior authorization or a quantity limit waived.

If the appeal fails, or you cannot wait

Cash-pay telehealth is the fallback, not the bargain: you pay the whole cost yourself, and a covered prescription is almost always cheaper than any of these. Use this route when coverage has actually been exhausted, or when you need to start while an appeal runs.
