Specialty Focus

Gastroenterology Billing That Captures What You've Earned

Gastroenterology is one of the highest-revenue and highest-risk specialties for billing errors. Colonoscopy coding alone — screening vs. diagnostic distinctions, polyp removal add-ons, anesthesia coordination — can make or break a GI practice's collections without expert billing management.

Prime Medical Billing's GI billing team specialises in endoscopy and colonoscopy coding, EGD and ERCP billing, polyp removal add-on codes, and infusion therapy for Crohn's and IBD patients. We navigate the screening-to-diagnostic conversion rules, coordinate with anesthesia billing, and manage prior authorisations for high-cost biologics.

Common Questions

Gastroenterology Billing — FAQ

Answers to the questions Gastroenterology practices ask us most before partnering with Prime Medical Billing.

Colonoscopy billing is nuanced: a screening colonoscopy that becomes diagnostic when a polyp is found requires a specific code set (G0121 → 45378 with modifier PT for Medicare). Polypectomy techniques — biopsy, hot snare, cold snare, EMR — each have distinct CPT codes. We apply the correct code based on the operative report technique description, preventing the most common GI denial causes.
When anesthesia is provided by a CRNA or anesthesiologist for GI procedures, we coordinate billing between the GI physician and the anesthesia provider. We also bill moderate sedation (99151–99153) when the GI physician provides and documents their own sedation administration.
Yes. Many commercial payers require prior auth for colonoscopy, capsule endoscopy, upper GI series, and hepatology procedures. We submit auth requests with the clinical indication, prior treatment failures, and supporting endoscopy reports — and we track all open authorizations to prevent scheduling delays.
ERCP (43260–43278) and other complex GI procedures involve multiple components — sphincterotomy, stent placement, stone removal — each billable when separately documented. We review operative reports line by line to ensure every documented component is captured and billed, maximizing reimbursement on high-complexity cases.
