The evidence we look for
Four ways a hospital bill quietly inflates
Every scan is cross-examined for these patterns — each one tagged with a plain-English reason and the exact dollar amount at risk.
A bigger code than the visit
The code on file describes more clinical complexity than what a service note actually supports — and costs you the difference.
Priced far past typical
Every CPT code has a benchmark range. We flag anything billed well outside it for your region, with the typical range shown alongside.
Balance billing you shouldn't owe
Patterns that may violate the No Surprises Act — cited by name in your dispute letter, with CMS guidance behind it.
Chain of custody
How the file gets built
No phone calls, no advocate fees, no two-week wait. About a minute from upload to verdict — and your dispute window is shorter than you think.
Step 1 — Intake
You submit the documents
Photos or PDFs of your itemized bill, and your EOB if you have one. No EOB yet? We still build a case from the bill alone.
Step 2 — Cross-examination
Every line is interrogated
We extract each charge, translate every CPT/HCPCS code into plain English, and match bill lines against your EOB side-by-side.
Step 3 — Verdict
You get the flag count free, then the full file
See your flagged total at no cost. Unlock the full line-by-line report and a ready-to-send dispute letter — also free, right now, no credit card.

Files that turned up something
Real scans from our earliest beta testers — the exact kind of errors your bill may be hiding too.
"My ER bill had the same blood draw billed twice. BillAutopsy caught it in under a minute — I'd never have noticed."
"I had no idea what half the codes meant. Seeing them in plain English made it obvious something was off."
"The letter cited the No Surprises Act by name. It gave me the confidence to actually send something."

Everything BillAutopsy automates, explained — in case you want to read your own bill like an investigator first.
How to read CPT/HCPCS codes without a medical degree
+
Every line on your itemized bill starts with a five-character code — CPT or HCPCS. CPT codes describe the service performed (an ER visit, an X-ray, a blood draw); HCPCS covers supplies and drugs CPT doesn't fully capture.
The complexity level after the code matters more than most patients realize. An ER visit billed 99285 (high complexity) instead of 99284 (moderate) can run a few hundred dollars higher — one of the most common places upcoding shows up.
Ask two questions of every line: does the description match what happened, and does the price look anywhere near typical? That two-step check is exactly what BillAutopsy automates the moment you upload your documents.
The No Surprises Act: what it actually protects you from
+
The federal No Surprises Act protects you from balance billing in specific situations: emergency care anywhere, and non-emergency out-of-network care at an in-network facility. In those cases you generally can't be billed more than your plan's in-network cost-sharing.
It doesn't judge whether a specific charge or code was accurate, and it doesn't apply if you knowingly went out-of-network and signed a consent waiver — it's a billing-relationship law, not a coding-accuracy law.
It becomes powerful in a dispute letter when your owed amount looks far larger than your plan's allowed cost-sharing — exactly when BillAutopsy's letter generator cites it by name, alongside CMS guidance.
Five signs your bill has an error, and how to prove it
+
1. The same code appears twice at the same price. 2. A code doesn't match your memory of the visit. 3. The price sits far outside the typical range. 4. A charge on the bill has no matching EOB line. 5. Your amount owed is much higher than your plan's allowed cost-sharing.
Proving any of these means lining the bill against the EOB, translating the codes, and writing down what each flag is worth — the entire first half of what BillAutopsy automates on upload.
Cross-examination
Questions people ask before opening a file
How soon do I need to dispute a bill?
Most providers give you 30–60 days from the bill date before sending it to collections, and the sooner you dispute, the more leverage you have. It takes about a minute to see whether your bill has errors worth disputing — worth doing before that window closes.
Do I need my EOB to use this?
No — a bill alone still gets flagged for duplicates, upcoding, and above-typical-rate charges. Adding your EOB unlocks the full bill-vs-insurance comparison, which usually finds the most.
Is my bill information kept private?
Yes. Your case file is private to your account — we don't sell or share it with providers, insurers, or anyone else.
Is this medical or insurance advice?
No. BillAutopsy only investigates billing — duplicate charges, coding mismatches, and pricing. Not medical advice, not coverage advice.
How much does opening a case cost?
Nothing, right now. BillAutopsy is completely free during beta — every scan and dispute letter is unlocked at no charge, no credit card required.
Will the dispute letter actually work?
It's written in the same formal structure — citing the No Surprises Act and CMS guidance — that paid billing advocates use. Results depend on your specific bill and provider; it isn't a legal guarantee.
What if the AI can't read my bill?
If a page can't be read clearly, we tell you and ask for a clearer photo — no silent failures, and you review every line before sending anything.
