CPT code 44392 captures a colonoscopic excision of one or more abnormal masses performed through a previously created colostomy stoma. Nationally, this code represents a specialized endoscopic intervention used when standard transanal colonoscopy is not feasible due to prior colectomy and colostomy formation. The procedure has clinical importance for surveillance, diagnosis, and treatment of residual colonic pathology, and for obtaining specimens for histopathologic evaluation.

Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of clinical intent and typical settings, alongside payer coverage context and commonly applied modifiers. The publication outlines benchmarking elements and relevant policy considerations that affect coding, claims adjudication, and site-of-service designation for colonoscopic procedures performed via colostomy access.
