ERCP with hot snare polypectomy
A patient presents for evaluation of a bile duct mass. He is post laparoscopic cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) with stent placement. A bile duct adenoma was noted that was not amenable to endoscopic resection. The endoscope was introduced through the mouth and advanced under direct visualization until bifurcation of the main biliary duct was reached. The biliary bile duct was deeply cannulated with a balloon and a wire. Abrupt shelf-like narrowing was identified in the periampullary bile duct consistent with the endoscopic ultrasound (EUS) findings of a mass in this region. Upstream bile duct was diffusely dilated about 14 mm. Visualized intrahepatic bile ducts appeared normal. Bile duct was swept from the bifurcation. Polypoid tissue was extruded from the distal bile duct during balloon sweeps. Subsequently a hot snare was used to resect polypoid tissue for histology. A 10 mm x 6 cm fully covered metal stent was deployed extending across this area from the bile duct into the duodenum. Since there is no CPT code that describes an ERCP with hot snare polypectomy, what is the appropriate code for this procedure? ...

Article Overview
This premium coding article focuses on an endoscopic retrograde cholangiopancreatography scenario involving a biliary mass, balloon-assisted duct evaluation, tissue removal with a hot snare, and placement of a fully covered metal stent. It is relevant to gastroenterology, endoscopy, and medical coding professionals who need to understand how the procedure context, documentation elements, and associated endoscopic findings relate to code selection and reporting considerations.
Why This Topic Matters
Biliary endoscopy cases often combine multiple procedural components and supporting findings, so accurate interpretation of the operative note is important for compliant coding and claim support. The article helps readers distinguish the documented procedural elements and related clinical context that may affect coding review.
What You Will Learn
- How the documented biliary endoscopy procedure is structured in the operative note
- What supporting clinical findings are documented around the bile duct mass
- How associated endoscopic interventions and stent placement are described in the case context
- What documentation elements are important for coding review in complex ERCP scenarios
Who Should Read This
- Medical coders
- Coding auditors
- Gastroenterology billing staff
- Clinical documentation specialists
- Revenue integrity professionals
