A summary bill often shows just a total. An itemized bill lists every item and service, which is what you need to find mistakes.
Steps (from CMS guidance)
- Ask the provider's billing department for a detailed bill listing the cost of each item or service. Our itemized bill request letter puts this in writing.
- If you used insurance, get your Explanation of Benefits (EOB) from your insurer and check that "your share" matches your bill. Your insurer may be able to fix errors with the provider.
- Ask for a copy of your medical records and compare them to the bill. CMS says you shouldn't be billed for anything that isn't documented in your records. Ask whether there's a records fee.
- Look for double billing, which CMS says is especially common when several providers treated you.
- Look up each billing code (search the code plus "medical billing code") and check that the description matches the care you got.
- Contact the billing department about anything that doesn't match. Use our billing dispute letter and keep copies.
Common things to check
- Same service, date or code listed twice
- Services or supplies not in your records
- Wrong dates, wrong patient details, or the wrong insurance
- A balance that doesn't match your EOB
