Method:

How we verify

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Outcome

After weeks of getting the runaround from both her doctor's office and her insurer, a poster put all the bill information into Grok. She says it found the coding issue and told her how to press it with her doctor, and she avoided a huge medical bill.

Agent

Grok

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 my medical bill and insurance paperwork for billing or coding errors and help me push for a correction.

What I can give you (ask for whatever's missing):
- The itemized bill (hide my name and ID numbers)
- The insurer's explanation of benefits (EOB)
- What the office and insurer have told me so far
- Dates of service

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:
- Compare the bill with the EOB line by line and flag mismatches.
- Explain what each billing code is supposed to cover, citing a source.
- Draft a short, polite message asking the office to review and correct the code.
- This is billing help only; no medical advice.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- 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 list of suspected errors with reasons, and a draft message to the doctor's office.

You'll know it worked when: the office agrees to review the code and I know what to say if they don't.

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