CPT 44390: Colonoscopy Through Colostomy Stoma with Foreign Body Removal
CPT code 44390 represents an endoscopic examination of the residual colon performed through an existing colostomy stoma, including identification and removal of foreign bodies. This procedure is clinically important for managing obstructions, preventing intestinal injury, and assessing the stoma-accessible colon after prior colectomy. Nationally, the code is used across acute and outpatient surgical settings where colostomy care and endoscopic access are required.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a longstanding colostomy following a low anterior resection for colorectal cancer presents for routine surveillance and evaluation of intermittent stoma bleeding and passage of mucus. The patient is scheduled for an endoscopic evaluation of the remaining colon through the existing colostomy stoma. In the pre-procedure workflow, the provider reviews history and indications, confirms informed consent, assesses anticoagulation status, and arranges appropriate bowel preparation through the stoma if required. On the day of service the patient is placed in a monitored procedural area (endoscopy suite) with intravenous access. The colonoscope is inserted through the previously created colostomy stoma to inspect the colonic mucosa for metachronous neoplasia, anastomotic recurrence, strictures, foreign bodies, or sources of bleeding. Therapeutic maneuvers may include removal of obstructing foreign material, targeted biopsies, or limited polypectomy if appropriate. Post-procedure, the patient is recovered in the observation area, given discharge instructions specific to stoma care and signs of complication, and follow-up arranged with the colorectal surgery or gastroenterology team as indicated.
