## What to include in your fax to Aetna

Complete the complaint and appeal form with the member and service details. Explain the decision or issue being challenged and include relevant bills, correspondence or other supporting evidence requested by the form.

## Check the destination and prepare your cover page

Name the receiving claims or appeals team and the request type. Include the policy, member or claim reference where the form asks for it, a callback number and the total page count. Put medical evidence in the required attachments rather than the cover summary.

Check the official source and recipient instructions before sending. A reviewed source confirms a published number, not live availability.

## Confirm delivery and follow up with Aetna

These are fax destinations, not voice support lines. Keep the transmission result and a copy of the documents. Confirm with the receiving department that the packet is complete and can be processed; a delivery receipt does not establish acceptance or a decision. Check with that department before sending a duplicate.
