Summary & Overview
CPT 44394: Colonoscopic Snare Excision via Stoma
CPT code 44394 identifies a colonoscopic snare excision performed through an existing stoma to visualize and remove tumors, polyps, or other abnormal intestinal tissue. This procedure is clinically important for patients with stomas who require endoscopic evaluation and therapeutic excision without transanal access. Nationally, accurate coding of this service supports appropriate clinical documentation, resource allocation, and claims processing for ambulatory surgical centers and hospital outpatient departments.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise national overview of coding intent, common billing practices, and contextual clinical use for patients with established stomas.
Readers will find: a clear definition of the procedure and typical sites of service; an overview of common modifiers and payer considerations (Data not available in the input for payer-specific rates); and guidance on where this code fits in clinical workflows. The content summarizes the service line and clinical context, highlights payer relevance, and points to areas where additional payer-specific policy details or reimbursement benchmarks may be sought.
Billing Code Overview
CPT code 44394 describes a colonoscopic procedure performed through an existing stoma. In this procedure, a colonoscope is inserted through an artificial opening in the patient’s skin (a stoma) to visualize the colon and remove tumors, polyps, or other abnormal intestinal tissue using a snare excision technique (a wire loop used for excision).
-
Service type: Endoscopic tumor or polyp excision via stoma
-
Typical site of service: Ambulatory surgical center or hospital outpatient department, performed through a stoma
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a long-standing colostomy presents for surveillance and polypectomy through the stoma. The patient reports intermittent bleeding and changed stool caliber. Pre-procedure evaluation includes review of anticoagulation, allergy history, informed consent, and bowel/stoma assessment. In the endoscopy suite or ambulatory surgery center, the colorectal surgeon or gastroenterologist performs a stoma examination, inserts a colonoscope through the existing stoma, advances to visualize the neoterminal colon, identifies a pedunculated polyp, and removes it using a snare (polypectomy) with electrocautery. Specimens are sent to pathology. Peri-procedural vital signs, conscious sedation or monitored anesthesia care, and post-procedure recovery with discharge instructions are part of the clinical workflow.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when reporting only the physician’s professional interpretation when separate technical component is billed. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned (e.g., limited visualization preventing full polypectomy). |
