What 44340 covers
A surgeon revises an existing colostomy with a limited, skin-level procedure, such as correcting a narrowed or poorly functioning stoma by revising its superficial opening. The work is confined to the stoma and does not involve deep bowel resection or reconstruction. This is typically performed by a colorectal or general surgeon in a hospital operating room or ambulatory surgical setting when local revision is needed to improve stoma function or fit with an ostomy appliance.
Report 44340 when the operative work supports a simple revision rather than a more extensive reconstruction or repair of a parastomal hernia. The operative note should identify the existing colostomy, the problem addressed, and the extent of revision. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is statutorily restricted, co-surgeons require supporting documentation, and team surgery is not permitted.
