Gastroenterology Billing & Credentialing
Screening vs diagnostic colonoscopy is where GI revenue leaks — modifier 33, PT and sedation rules decide whether you’re paid. We get every scope coded right.

Why gastroenterology is different
In GI, a screening colonoscopy that finds and removes a polyp becomes a diagnostic procedure — and without modifier 33 or PT the patient gets a surprise bill and you get a denial.
We code colonoscopies and EGDs to screening vs diagnostic rules, apply modifier 33 and PT when a screening turns therapeutic, bill moderate sedation correctly, handle ERCP and advanced procedures, and split pathology components.
