What Main AI finds

What we catch in your medical bill

Duplicate CPT codes
The same procedure billed twice — one of the most common and recoverable errors.
CMS Billing Guidelines
Surprise out-of-network billing
Federal law caps your out-of-network liability in emergencies at in-network rates.
No Surprises Act §2799B-1
Upcoded procedure
A simpler procedure billed as a more expensive one — fraudulent and disputable.
False Claims Act
Undisclosed facility fee
Facility fees must be disclosed before your visit — undisclosed ones are disputable.
CFPB Medical Billing Rules
Services never received
Charges for procedures, medications, or consultations that never actually happened.
CMS Fraud Prevention
Charity care not offered
Nonprofit hospitals must screen for and offer charity care — failure to do so is challengeable.
ACA §501(r)
