Summary & Overview
CPT 44401: Stomal Colonoscopy With Lesion Destruction
CPT code 44401 describes an endoscopic therapeutic procedure performed through a stoma to identify and destroy tumors, polyps, or other abnormal changes in intestinal tissue. It covers interventions that may be single or multiple and can include predilation, post-dilation, and guide wire passage when needed. Nationally, this code captures a specialized procedure that intersects surgical, gastroenterological, and ostomy care pathways and is relevant for payers managing post-operative and chronic intestinal disease populations.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing context for 44401, including typical settings of care (ambulatory surgery centers and hospital operating rooms) and the service type (stomal endoscopic therapeutic intervention). The publication also outlines common modifiers associated with this code and provides interpretation guidance for coding teams, billing staff, and clinical managers. Areas covered include benchmark considerations, clinical indications tied to stoma management, and payer coverage patterns where available.

Billing Code Overview
CPT code 44401 describes a procedure in which a provider inserts a colonoscope through an artificial opening in the patient’s skin (a stoma) to inspect the intestinal lining and observe and destroy tumors, polyps, or other abnormal tissue. The procedure may address single or multiple lesions and can include predilation and post-dilation as well as passage for a guide wire when required.
-
Service type: Endoscopic therapeutic procedure via a stoma (stomal colonoscopy with lesion destruction)
-
Typical site of service: Ambulatory surgery center or hospital operating room (procedures performed through an established stoma)
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a long-standing colostomy presents with intermittent bleeding and partial obstruction at the stoma site. The outpatient colorectal surgery clinic evaluates the patient, obtains a focused history, physical exam, and reviews recent imaging and labs. The patient is scheduled for a stoma colonoscopy under monitored anesthesia care in an ambulatory surgery center. The provider inserts a colonoscope through the existing stoma to inspect the mucosa, identifies several polyps and an ulcerated mass, and performs endoscopic tumor and polyp destruction using ablation techniques and/or mechanical removal. The procedure plan includes possible predilation of a stenotic stoma and post-procedure dilation if needed, and passage of a guide wire if endoscopic access to more proximal bowel is required. Specimens may be sent for pathology if biopsies are taken. Typical workflow steps: pre-procedure consent and history, anesthesia assessment, stoma preparation, colonoscopic inspection and treatment, immediate hemostasis as indicated, recovery room monitoring, post-procedure instructions and documentation of findings and codes for billing.
