What we check

Every check follows a fixed, public rule. Here is what we look for.

Duplicate charges
The same service billed more than once on the same day.
Math errors
Units times price that does not match the amount charged.
Wrong dates
Charges dated outside the time you were actually there.
Unbundling
Parts of one procedure billed separately when they should be billed together.
Quantity limits
More units billed than Medicare allows for a single visit.
Price outliers
Prices far above what Medicare pays for the same service.
Vague charges
Lump-sum or unlabeled charges that do not say what they were for.
Denied, then billed
Insurance denied a service, but you were billed the full amount. Needs your insurer's EOB.
Balance billing
The bill asks you to pay more than your insurer's EOB says you owe. Needs your insurer's EOB.

Findings come from public Medicare rules, not from AI guessing.

AI only reads your bill.

A fixed set of checks built on public Medicare rules decides what gets flagged, and the wording of each finding comes from fixed templates. The AI never decides what is wrong. It only turns your bill into structured data and, if you tap “What is this?” on a line, defines that one billing code.
