To file a grievance with Medicare you may call 1-800-Medicare (1-800-633-4227), available 24 hours a day, the seven days of the week. TTY (hearing impaired) users should call 711. You may also access the Medicare Grievance Form.

Plans are expected to disclose grievance, and appeals, upon request, to individuals eligible to elect a Medicare Advantage organization or a Part D Sponsor.  If you are interested in receiving this information, please contact our Member Services Department.


A grievance is an expression of dissatisfaction with any aspect of the operations, activities or behavior of a plan or its delegated entity in the provision of health care items, services, or prescription drugs, regardless of whether remedial action is requested or can be taken. A grievance does not include, and is distinct from, a dispute of the appeal of an organization determination or coverage determination or an LEP determination. Please consider that you should notify us within 60 calendar days after the issue or incident that cause the grievance, either in written or through phone.

In certain cases, you have the right to ask for an “expedited grievance,” meaning your grievance will have a resolution within 24 hours. For example, if your grievance involves a refusal to grant a request for an expedited coverage determination or an expedited redetermination and you have not purchased or received the drug in dispute, we must respond to your grievance within 24 hours. If not, we must notify you of our decision about your grievance as quickly as your case requires based on your health status, but no later than 30 calendar days after receiving your grievance. We may extend the timeframe by up to 14 calendar days if you request the extension, or if we justify a need for additional information and the delay is in your best interest.

For more information about Grievances, please refer to Chapter 9 of your Evidence of Coverage.

Appeals (Redeterminations)

If we deny any part of your request for coverage or payment or if you disagree with our coverage determination, you may ask us to reconsider our decision. This is called an “appeal” or a “request for redetermination”. If you want to appeal, you must request your appeal within 60 calendar days from the date included on the notice of our coverage determination.
