Appeals do not go to the claims boxes
The two claim boxes are for new paper claims. Disputes and appeals have their own addresses:
- Commercial appeals: Aetna Provider Resolution Team, PO Box 14020, Lexington, KY 40512. Fax 1-859-455-8650. Send a reconsideration first, to the address on the EOB or in Availity.
- Medicare appeals, contracted providers: Medicare Provider Appeals, PO Box 14835, Lexington, KY 40512. Fax 1-860-900-7995.
- Medicare appeals, non-contracted providers: PO Box 14067, Lexington, KY 40512. Fax 1-724-741-4953. You have 65 days when there was no reconsideration.
Deadlines for each step are in our Aetna timely filing guide.
Before you mail a paper claim to Aetna
- Try electronic first. Aetna takes claims through Availity and most clearinghouses. You get an acceptance report with a date, which is your proof of timely filing. A paper claim gives you no proof unless you send it tracked.
- Check the ID card. If the card names another administrator (Meritain, Signature Administrators), the Aetna boxes are wrong.
- Use a red-ink CMS-1500 (02/12). Paper claims are scanned. Photocopies and black-and-white prints get rejected.
- Keep the tracking number and the date you mailed it, in case Aetna says it never arrived.
Send us the list: payer, date of service, denial code and amount. No patient names needed. We will tell you which claims can still be fixed, which need an appeal, and which deadlines are close. Free, usually within 2 business days. Want the full picture? Get a free 90-day denial audit from your ERA files.
