Medicare Member Appeals

An appeal is when you want us to reconsider a decision we’ve made about your health plan or prescription drug coverage for services or benefits you’ve received.

Standard appeal – Generally, we use the standard deadlines for giving you our decision. For an appeal for a medical service, a standard coverage decision means we will give you answer within 14 days after we receive your request. (We may take more time if we need information that could benefit you. If we take extra time, we'll tell you in writing.) For a standard appeal for prescription drugs, we'll give you answer within 7 calendar days.

Fast appeal – If your health requires it, you can ask for a fast appeal. We’ll give you an answer within 72 hours after we receive your appeal.


To start an appeal, you, your doctor, or your representative, must contact us. Print out and complete the appropriate appeal form and mail or fax it to our appeals coordinator at the address below.
