Request an itemized bill, check every line for errors, and dispute in writing. A large share of medical bills contain mistakes that get removed when challenged.
Start by requesting a fully itemized bill — the summary version is designed to be unquestionable, and errors hide in the line items: duplicate charges, services never rendered, and unbundled codes billed separately. Compare it against your explanation of benefits and any records you have. Then dispute specific errors in writing. Even valid charges are frequently reduced when questioned, and if the No Surprises Act applies, some out-of-network bills may not be your responsibility at all.
