Medicare Part D Coverage Redetermination

If you have received an unfavorable drug determination, you can ask for redetermination (appeal) by following the instructions given in the determination or as outlined below. Some reasons you may want to ask for a redetermination may be for drug list exceptions, coverage rule exceptions, or tiering exceptions.

An expedited appeal can be requested for situations in which the standard resolution time frame could seriously jeopardize your (or the member’s) life or health, or the ability to regain maximum function. Refer to the Expedited appeal page.

You (member), a person you appoint, your prescribing doctor, or other prescriber can submit the Part D coverage redetermination request. Refer to the How to appoint a representative section for additional information.
