The deliverable

What is in your appeal letter

Not a form letter. Here is the real structure the AI builds for your specific denial, section by section.

Formal appeal structure

Your contact block, the date, the insurer's appeals address, and a heading that names the patient, claim number, and denial code. Then a clear statement of appeal, the argument, and a request for action.

Denial-code-specific arguments

The letter answers your exact denial reason and code (for example CO-50 not medically necessary), and references the specific CPT and ICD-10 codes from your claim with their official descriptions.

Citations to applicable law

Where they fit your denial, the letter cites real rules: your state insurance code, ERISA claims rights (29 U.S.C. 1133), ACA appeal protections, and the No Surprises Act for surprise out-of-network bills.

Your insurer's own policy

When your insurer publishes a medical policy that covers your service, the letter quotes that policy back to them word for word. It is hard for a plan to deny what its own rules say is covered.

Peer-reviewed evidence

For medical-necessity denials, the letter cites published clinical research by author, journal, and year to back up the case that your treatment is standard and appropriate.

Built to send

A print-ready PDF and Word file formatted for Certified Mail, a Spanish translation, an attachments checklist, and a ready-to-mail external-review (IRO) letter if you need to escalate.

This shows the letter structure, not a real case. Which laws and policies appear depends on your denial, so every letter is different. Counterclaim is in launch and has no verified outcomes to report, and an appeal is never guaranteed to succeed. The letter is an AI draft - read every line and check every citation before you send it.
