To file a complaint with Medicare you may call 1-800-Medicare, 24 hours a day, 7 days a week. TTY (hearing impaired) users should call 1-877-486-2048. You may also access the Medicare Complaint 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 any complaint other than one that involves a coverage determination. You should file a grievance if you have any type of problem with us or one of our network pharmacies that does not relate to coverage for a prescription drug. You must file a grievance, either verbally or in writing, no later than 60 days after the event or incident that precipitates the grievance.

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 complaint 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 complaint. 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 (Reconsiderations or 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 reconsideration or 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.

Request for Redetermination of Medicare Prescription Drug Denial- AppealDownload

You or someone you name to act on your behalf (your appointed representative) may request an appeal. You can name a relative, friend, advocate, attorney, doctor, or someone else to act for you. Others may already be authorized under State law to act for you. You must complete the Appointment of Representative Form.

How soon we decide on your appeal depends on the type of appeal. For an expedited (fast) decision about a Part D drug that you have not received, we have up to 72 hours to make a decision. For a claim redetermination we have up to 60 days; for a standard pre service redetermination we have a maximum of 30 days. You or your appointed representative may contact us:
