What the source did
- She gathered the year-to-date medical bills, EOB documents, receipts and her coverage details and uploaded them all to her Grok Bot.
- The bot compared them. She says she had overpaid one provider almost $3,000 and had several double-billing incidents.
- It also found claims the providers hadn't submitted correctly. She expects several thousand dollars to come off her outstanding bills because of that.
- Asked in a reply whether she had to point it at the double billing, she said it caught it on its own and she had missed it.
- The bot then wrote and sent emails to the providers she had overpaid, asking for a refund, with the documentation attached and citing a Texas law she says requires providers to refund within 30 days of notice.
- She called it worth the time it took to gather everything. Next she is building her tax files to run the same kind of review.
- A second user, @mvoltron, posted the same day that his "Home & Health" Grok Bot went through his EOBs and bills since 2025, found incorrect codes (such as denials that should have been in-network), and messaged the billing departments through his insurance and MyChart accounts. He says he has been reimbursed about $1,000 so far.
- Heads-up: both are small posts (8 likes and 0 likes when we checked). Her refunds were requested, not yet confirmed as paid; his ~$1,000 is as he stated it. The 30-day refund rule is her description of Texas law; check your own state's rules.

Our notes
- What it takes
- Grok Bot plus the paperwork: the year's provider bills and itemized statements, your insurer's EOBs, receipts or proof of payment, and your coverage documents. She shared no template; ours is built from her post and replies.
- Where it breaks
- Missing EOBs or receipts, counting a refund request as money back (hers were requested, not yet paid), citing a refund law that isn't your state's, and codes or network status it reads wrong.
- Human checkpoint
- You confirm each overpayment and double bill against the EOB and send every refund request yourself. Her bot sent the emails; in our version it never sends, logs in, pays or disputes without your yes.
- Tools involved
- Grok Bot, This year's medical bills and itemized statements, Your insurer's EOBs (explanation of benefits), Your receipts and proof of payment, Your plan's coverage documents

Copy the prompt
Ours Our version, built from her post and replies. She shared no template. Fill in the [BRACKETS].
Audit my medical bills for this year. Do not contact anyone.
I'm uploading: every provider bill and itemized statement, every EOB from my insurer, my receipts and proof of payment, and my coverage documents.
1. Build a table with one row per service: date, provider, what was billed, what the EOB says insurance paid, what the EOB says I owe, and what I actually paid.
2. Flag every row where I paid more than the EOB says I owe (overpayments).
3. Flag the same service billed more than once (double billing).
4. Flag claims that look submitted wrong: denied or processed out-of-network when the provider should be in-network, wrong codes, or a bill with no matching EOB.
5. For each flag, show the documents that prove it and how much is at stake. Mark anything you're unsure of as "check".
6. Total it: money I may be owed back, and money that may come off bills I still owe.
7. For each provider I confirm, draft a short refund or correction request with the dates, amounts and the supporting documents to attach. If I tell you my state has a refund deadline rule, cite it; don't guess the law.
Show me the drafts and wait. Never send a message, log in to a portal, pay anything, or dispute a charge without my explicit yes for that specific item.
Approval rule
🛡
In our version the bot only audits and drafts. You read every finding, check it against the EOB, and send each refund request or billing message yourself. She had hers send the emails. Sending, buying, posting, and deleting always need a human.
Set it up
- Collect the year's bills, itemized statements, EOBs, receipts and coverage documents into one folder.
- Upload them and paste the prompt.
- Check the table it builds against the EOBs. Confirm each overpayment and double bill yourself.
- For claims it says were submitted wrong (for example, out-of-network denials that should be in-network), call or message the provider or insurer and ask them to resubmit.
- Review each refund request draft, attach the documents, and send it yourself.
- Keep a running tally of what's requested and what actually comes back, as @mvoltron does ("still whittling away").
Common failures
⚠
- Missing paperwork. The review is only as good as what you upload; she gathered bills, EOBs, receipts and coverage before starting.
- Counting money as recovered before it arrives. Hers were refund requests; track what is actually paid back.
- Guessing the law. She cited a Texas refund rule; other states differ, so only cite one you've confirmed.
- Letting it message providers unchecked. Read every finding and draft before anything goes out.
Variations
- Work through the portals. @mvoltron had his bot log into his insurance and MyChart accounts and message the billing departments. If you do this, approve each message first.
- Go after denials too. His finds were mostly incorrect codes and denials that should have been in-network.
- Run it on tax files next. She says that's her next project.
