HCPCS G6023: Flexible Sigmoidoscopy with Transendoscopic Stent Placement
HCPCS Level II code G6023 denotes a flexible sigmoidoscopy with transendoscopic stent placement, including predilation. This therapeutic endoscopic procedure is used to relieve distal colonic obstruction or to restore luminal patency and is commonly performed in ambulatory surgical centers and hospital outpatient departments. Nationally, accurate coding for stent placement during sigmoidoscopy affects procedure tracking, resource utilization, and claims adjudication for complex lower gastrointestinal interventions.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, standard sites of service, and the implications for billing workflows. The publication provides benchmarks and policy-relevant considerations such as typical coverage alignment among major commercial insurers and Medicare, coding specificity for endoscopic stent procedures, and items to verify during claim submission.
This summary equips billing managers, clinicians, and policy analysts with the essential facts about HCPCS Level II code G6023, what it represents, and where it fits within outpatient endoscopic services. Data not available in the input is noted where applicable; the main content focuses on the code definition, payer coverage list, and expected operational contexts for the procedure.
Billing Code Overview
HCPCS Level II code G6023 describes a flexible sigmoidoscopy procedure with transendoscopic stent placement, and specifies that the service includes predilation. This procedure involves endoscopic evaluation and placement of an intraluminal stent within the distal colon or sigmoid colon to relieve obstruction or maintain luminal patency.
-
Service type: Endoscopic therapeutic procedure (sigmoidoscopy with stent placement)
-
Typical site of service: Ambulatory surgical center or hospital outpatient department

Clinical & Coding Specifications
Clinical Context
A 64-year-old patient with a history of colorectal cancer treated with prior surgery presents with progressive left lower quadrant abdominal pain, obstructive bowel symptoms, and a change in bowel habits. Cross-sectional imaging demonstrates a short-segment malignant-appearing stricture of the sigmoid colon causing partial obstruction. The gastroenterology team schedules a flexible sigmoidoscopy with transendoscopic stent placement to palliate the obstruction.
The clinical workflow: the patient undergoes pre-procedure evaluation including informed consent, assessment of anticoagulation, and bowel preparation as indicated. In the endoscopy suite or ambulatory surgical center, sedation is administered and a flexible sigmoidoscope is advanced to the lesion. The stricture is evaluated, and predilation is performed if needed to allow passage of the delivery system. Under endoscopic and fluoroscopic guidance, a self-expanding metallic stent is deployed across the stricture. Post-placement imaging confirms position and luminal patency. The patient is observed for immediate complications and discharged with post-procedure instructions and follow-up arrangements, including coordination with oncology and surgical teams as appropriate.
