What you'll accomplish

By the end of this guide, you'll have ChatGPT set up to draft a complete, professional prior authorization appeal letter in under 5 minutes — instead of the 30–60 minutes it currently takes. You'll also learn how to feed in the right clinical context so your appeal letters are specific, persuasive, and tailored to each payer's criteria.

What you'll need

  • A free ChatGPT account (chat.openai.com) — no credit card required
  • The insurance denial notice (letter or portal message) for the case you're appealing
  • Basic clinical information from the physician's notes (diagnosis, procedure, why it's necessary)
  • Time needed: 15 minutes to learn; 5 minutes per appeal after that
  • Cost: Free (ChatGPT free tier is sufficient for this)
