What is the Aetna provider appeal fax number?

Aetna’s Provider Complaint and Appeal Request form lists National Fax (859) 455-8650 for the Provider Resolution Team (PO Box 14020, Lexington, KY). Always confirm on your current EOB or Aetna correspondence—Medicare and prior-auth use other numbers.

Is this the same as Aetna prior authorization fax?

No. Prior authorization often uses a different line (commonly listed as (888) 632-3862 on PA materials). Use (859) 455-8650 only when your appeal / Provider Resolution instructions list that national fax.

Can I fax Aetna provider appeals from this page?

Yes if your Aetna materials list this number. The fax is pre-filled—upload your PDF, pay once ($1.99 for up to 3 pages), and track delivery.
