What a medical bill audit finds
Medical bills are coded with CPT (Current Procedural Terminology) codes, and billing errors are common. Three patterns this tool looks for: duplicate charges (the same CPT code billed more than once — the sample bill lists CPT 80053 twice, a $180 overcharge), upcoding (a higher, more expensive visit level than the service supports, e.g. 99285 when 99284 fits), and unbundling (separately charging for services normally bundled into a single fee, like an EKG that belongs with an ER visit). Beyond the errors, the calculator can split the corrected total by insurance: you pay your remaining deductible first, then coinsurance on the rest, capped by your out-of-pocket maximum.
Left: an itemized bill with a duplicated CPT 80053 flagged — one $180 charge is an overcharge. Right: the $3,885 total split by a plan covering 80% with $500 deductible left and a $3,000 out-of-pocket max: plan pays $2,708, you owe $1,177.
The sample bill totals $3,885. Pasting it triggers an automatic audit: it lists CPT 80053 (comprehensive metabolic panel) twice, bills two ER visit levels (99284 and 99285), and itemizes an EKG that is often bundled with an ER visit.
- Duplicate found:CPT 80053 billed twice → one $180 charge is an overcharge
- Level conflict:Both 99284 and 99285 billed — only the correct ER level should be charged
- Insurance split:80% coverage, $500 deductible left, $3,000 OOP max → plan pays $2,708, you owe $1,177
- Dispute letter:The AI drafts a formal letter citing each code and amount to send to billing

Frequently asked questions
What are the most common medical billing errors?
Duplicate charges for the same service, upcoding (billing a more expensive version of a procedure than performed), services dated after discharge, unbundled charges that should be bundled, and balance billing beyond in-network agreed rates. The analyzer flags each pattern and explains what to ask the billing office.
Can I dispute a medical bill myself?
Yes, and many people succeed: request an itemized bill, question flagged charges in writing, and ask about financial assistance policies — hospitals frequently settle or correct without formal appeals. The generated dispute letter gives you the professional wording; you send it to the billing department yourself.
