Gastroenterology Medical Billing Services

Billing that knows your specialty's rules

GI billing hinges on scopes: screening versus diagnostic colonoscopy rules, the modifier 33 and PT distinctions that decide patient cost-sharing, multiple-endoscopy payment reductions, and anesthesia coordination.

We code scopes to what the report supports, apply screening modifiers so patients aren't wrongly billed, and manage the multiple-procedure math payers love to get wrong.

What we handle for gastroenterology practices
