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 an NC State Health Plan contact fax?

Some plan Contact Us pages (for example NC State Health Plan) list the same Aetna national fax (859) 455-8650 but may show a different mail stop (e.g. PO Box 14079). Use the fax and address printed on YOUR appeal form or EOB—not a generic contact page.

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.
