Check a year of health insurance claims for overpayments
In a short reply, the poster says he had Grok Bot go through all of his family's health insurance claims for the year, and it showed they had overpaid about $3,200 in medical bills. He doesn't say yet whether any money came back. Comparing each bill with the insurer's explanation of benefits is exactly the slow job where overpayments hide.
Poster's claim, not verified: The poster says the check showed about $3,200 in overpayments. We haven't verified it.
Copy this prompt
Here are my explanation of benefits statements from [INSURER] and the bills I paid this year. Match each bill with its claim. Flag any bill where I paid more than the 'patient responsibility' amount, any charge billed twice, and any claim that was denied. Put it in a table with the date, provider, what I paid, what I owed and the difference.

Watch out for
- Call the provider's billing office with the claim number before you assume a refund. Payments can be applied to other visits.
