What is the Aetna fax number?

Aetna uses different fax numbers by function and plan type, including separate lines for appeals, prior authorization, claims, provider services and Medicare plans. Use the number printed on your letter or form, or call the number on your member card and ask for the fax line for your specific need.

Can I fax Aetna without a fax machine?

Yes. An online fax service sends your documents over the fax network from a phone or computer. With Just The Fax it is $1.99 for up to 15 pages, with no account or subscription.

What should I include when faxing an Aetna appeal?

A cover sheet with your name, member ID as printed on your card, date of birth, the claim or reference number from the denial letter and a callback number, plus the signed appeal form and any supporting documentation the letter requested.

How do I prove I sent my Aetna appeal on time?

Keep the fax delivery confirmation showing the date and time of successful transmission to the appeals fax line, then call after a few business days to confirm receipt and get a case number.

How to Fax Aetna

Aetna still takes a lot of paperwork by fax -- appeals, prior authorizations, claim forms, provider updates. The hard part is not sending it. The hard part is sending it to the right place.

There is no one Aetna fax number

Aetna runs separate fax lines by function and often by plan type. The common split:

Appeals and grievances -- one line, and it is usually different for medical vs pharmacy appeals
Prior authorization / precertification -- frequently split again into pharmacy and medical
Claims submission and reconsideration
Provider / practitioner services -- credentialing, demographic updates, W-9s
Medicare plans -- often entirely separate numbers from commercial plans

A prior auth sent to the claims line does not get rerouted. It gets set aside.

Finding the right number

The letter or form in front of you. Denial letters, EOBs, precert forms, and appeal notices print the destination fax number, already routed to the correct department. This beats every other source.
The back of your member card. Call and ask for the fax number for your specific need -- name the department and say whether it is pharmacy or medical, commercial or Medicare.
Your provider's office. They submit to Aetna constantly and usually have the current direct lines.
Our free [insurance fax directory](https://justthefax.io/directory/insurance) -- verified insurer fax numbers checked against an official source before publishing. Free, no signup. If your letter names a number, use that instead.

Numbers on old letters and third-party lists go stale. Confirm before you send anything with a deadline attached.

What to include

A cover sheet with your name, Aetna member ID exactly as printed, date of birth, the claim or reference number from your letter, and a callback number. Free insurance cover sheet here.
The reference number. Without it your fax cannot be matched to the decision you are responding to.
Every page, signed where required. Unsigned appeal forms come back.
Supporting documentation -- chart notes, a letter of medical necessity, itemized bills, whatever the letter asked for.

If it is time sensitive -- an expedited appeal or urgent precert -- mark it clearly. Our urgent cover sheet is built to be visible in a stack of paper.

Sending it without a fax machine

Full disclosure: we make Just The Fax. It is a send only online fax service: $1.99 for up to 15 pages, no subscription, no account to create. Longer packets are $2.99 (16-50 pages) or $4.99 (51-100).

Have your documents as a PDF, or photograph each page.
Go to justthefax.io/send.
Enter the Aetna fax number from your letter or form.
Upload the pages and add a free cover sheet with your member ID.
Pay and send. You are only charged if the fax delivers.

Your document is deleted the moment the fax finishes. No account, nothing kept. We are a general purpose fax service, not a HIPAA Business Associate, and we do not sign BAAs -- we just do not retain your file.

Save the delivery confirmation. Appeals have deadlines, and a timestamped confirmation that you transmitted to the appeals line on a given date is the record that protects you.

After you send

Give it a few business days, then call and confirm receipt and ask for the reference or case number. If an appeal is denied again, the response letter will explain your next level of review -- external review is often available after internal appeals are exhausted.
