Know exactly what's worth questioning — before you pay it.
Itemized medical bills are built to be unreadable — cryptic codes, flat-rate catch-alls, duplicate lines, charges for things that should already be included. Most people just pay, because they don't know what to ask. FairBill reads your bill line by line, flags what's structurally worth questioning, and drafts the letter for you.

🔒 Black out your name and date of birth before pasting — FairBill doesn't need them to audit the charges, and nothing you paste is ever stored. See how this works.
Structural red flags, not a price verdict
Paste your bill
The itemized text — line descriptions, codes, quantities, charges. No upload, no OCR, no account to create. Black out your name and date of birth first; FairBill doesn't need them.
AI flags what's worth asking about
Gemini reads every line for duplicate charges, unbundling, vague catch-alls, quantity anomalies, routine items billed separately, and balance-billing indicators — all visible from the bill itself.

FairBill never claims a charge is above Medicare, a CPT rate, or any other price benchmark — it has no pricing database, and inventing one on a medical bill would be dishonest. It only flags what's structurally visible on the bill, phrased as worth asking about, never as a verdict. It doesn't verify anything with your insurer or provider, and it isn't legal, medical, or financial advice.

Surprise and inflated medical bills hit millions of Americans every year
An estimated 1 in 5 privately insured hospital admissions still results in a surprise or disputed medical bill, and medical billing errors are common enough that patient advocates routinely recommend requesting an itemized bill and checking it line by line before paying.
