How to read an itemized medical bill

An itemized bill lists each service or supply, its date, charge, and any payments or adjustments. Use it to check what was billed before deciding whether to question a charge.

Check the bill

1. Confirm the patient, provider, account number, and dates of service.
2. Ask the billing office for an itemized statement if you have only a balance summary.
3. Match each description or code to the care you remember; ask the provider to explain unfamiliar lines.
4. Check charges, insurance adjustments, payments already made, and the remaining balance.

Synthetic example

A fictional bill lists a lab test twice for the same date at $80 each. That is a reason to ask whether two tests were performed; the repeated lines alone do not prove an error.

Limits

A description may be abbreviated, and a repeated service can be appropriate. Verify against records and the provider’s explanation before disputing.
