Process for Medicare coverage requests, appeals & complaints

Let us know if you have a concern about your coverage or care. Call us at the number on your member ID card to discuss your concern.

As an Aetna Medicare member, you have the right to:

  • Ask for coverage of a medical service. In some cases, we may allow exceptions for a service that is normally not covered.

  • File an appeal if we deny your request. An appeal is a formal way of asking us to review and change a coverage decision we made.

  • File a complaint about the quality of care or other services you get from us or from a Medicare provider.

There are different steps to take, based on the type of request you have. 

If you're asking for a medical service under your Medicare Advantage plan, that's called a coverage decision (organization determination). 

You can call us, fax or mail your information.

Call1-800-245-1206 (TTY: 711), Monday to Friday, 8 AM to 8 PM ET.

Rights”. You’ll have to sign it to show you understand your rights as a hospital patient, including:

  • Your right to receive Medicare-covered services during and after your hospital stay, as ordered by your doctor. This includes the right to know what these services are, who will pay for them and where you can get them.

  • Your right to be involved in any decisions about your hospital stay, and know who will pay for it. 

  • Where to report any concerns you have about quality of your hospital care. 

  • Your right to appeal your discharge decision if you think you're being discharged from the hospital too soon.

You have the right to keep getting your covered services for as long as the care is needed to diagnose and treat your illness or injury if you’re getting:

  • Home health care

  • Skilled nursing care as a patient in a skilled nursing facility

  • Rehabilitation care as an outpatient at a Medicare-approved Comprehensive Outpatient Rehabilitation Facility (CORF). (Usually, this means you’re getting treatment for an illness or accident, or you're recovering from a major operation.)

You’ll receive a "Notice of Medicare Non-Coverage (NOMNC)" in writing at least two days before we decide it’s time to stop covering your care. When your coverage for that care ends, we'll stop paying our share of the cost for your care. You can ask to change this decision so you're able to continue coverage. 

Level 1 Appeal

You must contact the Quality Improvement Organization to start your appeal no later than noon of the day after you receive the written notice telling you when we will stop covering your care.

If you miss the deadline for contacting the Quality Improvement Organization about your appeal, you can make your appeal directly to us instead.

When you’ll hear back

We’ll tell you our decision within 48 hours.

Level 2 Appeal

You may ask for this review immediately, but must ask within 60 days after the day the Quality Improvement Organization said no to your Level 1 Appeal. 

When you’ll hear back

The Quality Improvement Organization will respond to you as soon as possible, but no later than 14 days after receiving your request for a second review.
