Summary & Overview
CPT 44402: Colonoscopy via Stoma with Endoscopic Stent Placement
Headline: CPT code 44402: Colonoscopy via Stoma with Endoscopic Stent Placement
Lead: CPT code 44402 describes endoscopic evaluation of the colon performed through a stoma, combined with endoscopic insertion of a stent. The code captures a targeted interventional procedure used in patients with an established stoma who require decompression, palliation, or treatment of obstructive lesions.
CPT code 44402 matters nationally because it represents a specialized endoscopic service combining diagnostic and therapeutic elements in a population with altered gastrointestinal anatomy. This procedure can affect hospital workflow, device utilization, and outpatient surgical scheduling, and it has implications for coverage policies and prior authorization processes across major payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The content that follows provides benchmarking context where available, summaries of payer coverage themes, and clinical coding considerations for claims submission.
Readers will learn: an overview of what CPT code 44402 represents clinically and operationally; typical sites of service and service type; common modifiers and billing considerations (listed elsewhere); and how the code relates to clinical scenarios involving stoma-based access and endoscopic stent placement. Data not available in the input will be indicated where applicable.
Billing Code Overview
CPT code 44402 describes a procedure in which a provider performs a colonoscopy through an existing stoma (an artificial opening in the skin) and endoscopically introduces a stent.
-
Service type: Endoscopic stoma-based colonoscopy with stent placement
-
Typical site of service: Hospital outpatient department or ambulatory surgical center where endoscopic procedures and stent placement are performed
Clinical & Coding Specifications
Clinical Context
A typical patient is a 65-year-old with a permanent end colostomy after prior colorectal cancer resection who presents with progressive stoma obstruction symptoms (abdominal pain, distention, decreased stoma output). After cross-sectional imaging suggests malignant or benign stricture at the stoma or just proximal to it, the patient is scheduled for a stomal colonoscopy with endoscopic stent placement through the stoma. The clinical workflow includes pre-procedure evaluation (history, anticoagulation review, informed consent), bowel prep tailored for a stoma, periprocedural antibiotics if indicated, conscious sedation or monitored anesthesia care, endoscopic examination via the stoma to identify the lesion, dilation if needed, and endoscopic introduction and deployment of a enteric/colonic stent to relieve obstruction. Post-procedure monitoring includes recovery from sedation, stoma output assessment, pain control, and discharge instructions with follow-up for stent surveillance and potential oncology or surgical consultation.
