Privacy-first — your bill is analyzed in your browser

Your medical bill is
probably wrong.

Four out of five itemized hospital bills contain errors. We check yours for duplicate charges, prices above Medicare rates, unbundled codes, and impossible quantities — then write the dispute letter for you. A flat $20, not 15% of your savings.

What we catch

Four errors that quietly inflate your bill

These four account for the overwhelming majority of overcharges. Switch between them to see exactly how we flag each one.

The same charge, billed twice

A duplicate is the single most common billing error — a code keyed in twice, or one procedure split across two line items on the same day.

Identical CPT/HCPCS codes on the same date of service
Room-and-board days that exceed your actual length of stay
Lab panels billed both bundled and à la carte

Duplicates are among the most common billing errors.

Questions

Good to know

Yes. Parsing and analysis run entirely in your browser using JavaScript and a local copy of the public rate data. Your bill, your name, and the line items are never uploaded to our servers — there's nothing for us to leak, sell, or hand over.

We compare each CPT/HCPCS code against published Medicare fee schedules, run duplicate detection across dates of service, and check NCCI bundling rules and plausible quantity limits. We surface likely errors with the supporting numbers so you can judge each one — we don't guess at clinical necessity.

Itemized hospital and facility bills with line-item codes and charges. If you only have a summary bill, we generate an itemized-bill-request letter first — providers are required to give you the detailed version on request.

Then you've bought peace of mind for $20, and you'll know your bill holds up. You only pay when you choose to download a letter, so a clean bill with nothing to dispute costs you nothing.

No — and that's the point. Advocates who negotiate take 13–15% of your savings. We hand you a precise, code-cited letter you send yourself, so the full reduction stays in your pocket.

Public sources only: the CMS Medicare Physician and Lab Fee Schedules, hospital price-transparency files, DRG benchmark rates, and the NCCI procedure-to-procedure edits. Every flag links back to the rule it's based on.

You already paid for the care.
Don't overpay for the paperwork.

Scan your bill in five minutes. Pay nothing until you have a letter worth sending.

A note on accuracy

The Medical Bill Auditor is an automated tool. It compares your charges against public benchmark data and flags items that look like errors — but automated analysis can be incomplete or wrong. Codes may be miscategorized, benchmark rates can lag real-world pricing, and a flagged charge can turn out to be entirely correct. Nothing here is legal, medical, billing, or financial advice. Always review each flag yourself and confirm with your provider or insurer before disputing or withholding any payment. You decide what to send and are responsible for it; Medical Bill Auditor is not liable for the outcome of any dispute, for an error it does not catch, or for any amount you are ultimately charged.
