Draft appeal letters from denied insurance claims

An automation watches for denied claims, gathers patient details, and drafts a formal appeal for staff to review.

Done with Custom agent· Advanced· Sep 2026

What they did
A developer set up an n8n flow that starts when a claim is marked denied. It skips claims that have already been appealed, then pulls the patient record, prescriptions, and test results linked to that patient ID. An AI step then infers the most likely denial reason and writes a formal appeal letter based on the clinical evidence.
How it went
The system creates a Google Doc with the draft, updates a tracking sheet, and emails staff a branded message with a review link. No outcome metrics were reported.
Tips
Keep a human in the loop before any submission. Make sure the automation can exclude claims that have already been appealed and only uses approved source records.

Try it yourself with Claude Code

Help me build an automation that watches [claim source] for claims marked denied, skips any that have already been appealed, and pulls the related patient record, prescriptions, and test results from [data source]. Draft a formal appeal letter that states the likely denial reason and supports it with the clinical details. Save the draft in [document location], update [tracking sheet], and notify [staff email/system] with a review link. Pause and ask for approval before any letter is sent, submitted, or otherwise finalized. Then run it on one sample denied claim and show me the draft letter.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
