What is a Medicare grievance?

Enrollees in a Medicare health plan may file a grievance, also known as a complaint, if they are unsatisfied with their treatment by those who administer their Medicare Advantage or Medicare Part D plan. Conversely, an enrollee would file an appeal to complain about a treatment decision or service that is denied coverage.1

A grievance may or may not involve a request for remedial action (as opposed to an appeal, in which the enrollee is specifically asking that a plan decision be overturned).2

Examples of situations in which a Medicare beneficiary might file a grievance include:3

The Medicare grievance process is only used by Medicare enrollees and their representatives/caregivers. Healthcare providers use a different complaint/dispute resolution process.2
