Compare an EOB with the Provider Bill, Line by Line
An Explanation of Benefits is not itself a bill; keep the two documents distinct before you compare amounts.
Compare user-transcribed service labels and amounts from an EOB and provider statement; highlight differences for a human follow-up.
What changes the result: the service labels, dates, billed amounts, and plan amounts printed on your documents.
Privacy: Calculations run in this browser tab. This tool has no input-upload, account, or AI endpoint. The site may send a page-view signal to Cloudflare; this tool does not add form entries to that signal. A draft is stored only if you choose “Save draft on this device”; that browser storage is not encrypted. Avoid identifiers or sensitive details, and delete saved drafts when finished.
Your entries
The starting rows below are fictional examples. Edit them, replace them with non-sensitive labels and values, or load the sample again. The result is not advice or a source verification.
Amount fields use the same units you enter; the app does not choose a currency. Dates are the ones you provide. Up to 100 rows per run.
Calculated output
What the calculation does
For each line, subtract the entered planned amount from the entered actual amount. The summary adds the plan and actual columns separately, then reports their difference. It does not label a charge valid or decide whether a change was authorized.
Question to keep open: Does a difference prove an error, or is it a prompt to ask the provider or plan how each amount was processed?
Boundary: A numeric difference is not proof of a billing error or a determination of what you owe. Confirm with the provider and health plan; do not paste names, member IDs, or diagnosis details.
Copy includes the headline, aggregate metrics, and boundary—not the row-by-row input. The CSV contains entries you choose to download. Review it before sharing.
