Add your charges below. We flag duplicate billing, common upcoding patterns, unbundling, and charges that don't match typical rates.
Medical bills are generated from coded line items, and coding mistakes are common. The single most useful step is to request a fully itemized bill — not the summary — because the summary hides the individual charges where errors live. Once you have the itemized version, you can compare it against your insurer's Explanation of Benefits (EOB) to see what was billed, what was allowed, and what you actually owe.
The most frequent problems are duplicate charges for the same service, quantity errors (being billed for more units than you received), unbundling (charging separately for things that should be one code), and services you never received. Surprise out-of-network charges are their own category and, in the U.S., are limited for many emergency and facility situations. The checker above helps you flag lines worth questioning.
What this tool looks at:
Duplicate charges, incorrect quantities, unbundled codes billed separately, and charges for services never provided. Comparing an itemized bill to your EOB surfaces most of them.
Call the billing department and ask for a fully itemized statement with every line item and code. Providers are generally expected to supply one on request. The summary bill is not enough to check for errors.
An Explanation of Benefits is the statement from your insurer showing what the provider billed, what insurance allowed, and what you owe. If the bill asks for more than the EOB says you owe, that gap is worth questioning.
Yes. You can ask the provider to correct errors in writing and, where relevant, involve your insurer. Main AI can read the itemized bill and draft that dispute; this tool is informational and not medical or legal advice.
