Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Help me ask my doctor's office to lower a bill, using the insurance rules that apply.

Fill in before running:
- The bill and my insurance explanation of benefits (personal details removed): [UPLOAD]
- My plan type and insurer: [PLAN]
- What I think is wrong, if anything: [NOTES]

You're not my accountant or financial adviser. Show your working, label estimates as estimates, and tell me which points a professional or the official source should confirm.

Rules:
- Compare the bill with the explanation of benefits and list any mismatch, with line numbers.
- Name the rule or policy point behind each request and label it as something to confirm with the insurer.
- Draft a short, polite note to the billing office asking for a specific correction or reduction.
- Don't invent rules or numbers.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.
- List what the billing office might ask for, so I'm ready.

Output: A list of issues with the reason for each, and a ready-to-send note to the billing office.

You'll know it worked when: the billing office corrects or reduces the bill.

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

  • Appeal a surprise dental bill with ChatGPTRecreated promptEvidence: Article or interview

    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.

    Medical Xpress reports that Lauren Gonzalves spent almost two years fighting an $1,800 Anthem bill for her newborn's hospital nursery care. After a free AI appeal assistant (Counterforce's Maxwell) pointed to supporting reasons, she asked ChatGPT how to escalate a grievance with Anthem and got email addresses at a company handling the insurer's complaints. Within days an analyst found the claim, and a week later the bill was dismissed, she says.

  • Two years after an ER visit, Jackie Davalos got a collections notice saying $22,604 was owed to the hospital, having never received a bill; the records wrongly listed Davalos as uninsured. A first dispute only removed one medication charge. Davalos's partner, Walter Kerr, uploaded the billing and medical records to Claude and asked whether they had any further recourse. Claude suggested several arguments, including that legal requirements on debt and insurance might not have been met. Using many of them, Kerr wrote to executives at the hospital and its parent company, and shortly after the hospital waived the entire bill, later acknowledging a clerical error. A legal aid lawyer who reviewed it said some of Claude's analysis was right but it misunderstood some of the laws it cited.
