Summary & Overview
HCPCS G6025: Colonoscopy with Transendoscopic Stent Placement
HCPCS Level II code G6025 denotes a flexible colonoscopy performed proximal to the splenic flexure that includes transendoscopic stent placement and any necessary predilation. This code is used to capture endoscopic therapeutic interventions to relieve or bypass obstructive pathology in the proximal colon. Nationally, accurate coding for stent placement during colonoscopy matters for procedure classification, outpatient/inpatient billing workflows, and clinical documentation of complex endoscopic therapy.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents, the clinical context for stent placement during colonoscopy, and the typical sites where the service is delivered. The publication provides benchmarks and coding context where available, highlights relevant policy considerations for major payers, and outlines how this HCPCS Level II code fits into broader endoscopy service lines. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code G6025 describes a flexible colonoscopy performed proximal to the splenic flexure with transendoscopic stent placement, including any predilation performed as part of the procedure. This service involves endoscopic placement of an intraluminal stent during a colonoscopic examination to relieve or bypass an obstruction in the proximal colon.
Service type: Endoscopic therapeutic procedure (colonoscopy with stent placement)
Typical site of service: Ambulatory surgery center or hospital endoscopy suite (inpatient or outpatient settings based on clinical need).
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a history of colorectal cancer treated with prior resection presents with progressive abdominal pain, distension, and obstipation. Imaging (CT abdomen/pelvis) demonstrates a malignant stricture in the transverse colon proximal to the splenic flexure with upstream colonic dilation. Endoscopic evaluation with a flexible colonoscope is planned for decompression and palliation via transendoscopic stent placement across the obstructing lesion; predilation of the stricture may be performed endoscopically to allow stent passage. The procedure is performed in an endoscopy suite or hospital operating room by a gastroenterologist or colorectal surgeon with conscious sedation or monitored anesthesia care. The clinical workflow includes pre-procedure consent and risk assessment, targeted bowel preparation or enemas as appropriate, intraprocedural fluoroscopic or endoscopic guidance for stent deployment, documentation of stent type/size and dilation steps, post-procedure observation for perforation or bleeding, and arranging follow-up imaging or clinic visit to assess symptom relief and stent position.
