Outcome

After a new dentist's visit left her owing $1,201.80 on top of the $2,111.29 she'd already paid, Jamie Phillis gave ChatGPT her call transcripts, receipt, explanation of benefits and her insurer's appeal instructions. It wrote a formatted appeal letter in under a minute and flagged duplicate evaluations and a charge at seven times the allowed rate. The first appeal was denied; ChatGPT then drafted a second-level appeal and a complaint to the Arizona Department of Insurance. She says the case was never formally resolved, but the office never sent her a bill for the uncovered balance and she never paid the $1,200.

Agent

ChatGPT

The source didn't share its exact prompt, so we wrote this from what it describes.

Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points.

Goal: Check a medical or dental bill against my insurance paperwork, find charges worth disputing, and draft the appeal.

What I can give you (ask for whatever's missing):
- The itemized bill or receipt
- My explanation of benefits (EOB)
- My insurer's appeal instructions and deadline
- Notes or transcripts from calls with the insurer or provider
- My state (for the insurance regulator)

This is admin help, not medical advice. Don't diagnose or suggest treatments. If anything I mention sounds urgent, tell me to contact a doctor or emergency services first.

Rules:
- Go line by line: flag duplicate or overlapping services, charges above the allowed amount on the EOB, and anything I didn't agree to.
- Quote the exact bill line and EOB line for each issue, and show the math.
- Write the appeal in the format my insurer requires, factual and polite, with a clear request.
- If an appeal is denied, explain the next level (second-level appeal, state insurance department complaint) and draft it when I ask.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A table of disputed items with reasons and amounts, then the appeal letter and mailing or submission steps.

You'll know it worked when: each disputed charge is backed by a document line, and the letter follows my insurer's instructions.

- Keep a dated log of every call, letter and reference number so I can cite it in later appeals.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
