STEP 2
Read and extract
Base rate code, mileage units, origin and destination modifiers, supplies, and charges are pulled into a structured claim.

STEP 4
Run the ambulance checks
Every line is tested against the detection modules below.
STEP 5
Write the letter
A plain-English findings summary plus a ready-to-send dispute letter, with each finding cited.

05 — THE QUESTION EVERYONE ASKS
So what do I actually get back?
Three answers, honestly ranked. Most of the value is in the first two.
You already paid it → you get refunded
A charge that was duplicated, miscoded, or never rendered is refunded to you directly by the transport company.
You haven't paid yet → you stop owing it
Your coinsurance is a percentage of the charge, and a balance bill is the whole gap. Correcting the level of service or the mileage lowers both.
The insurer or Medicare was overbilled → they recover it
Those funds return to the payer, not to you. Reporting can carry a small reward. Large recoveries run through whistleblower actions, which require an attorney — not an app.
