What 44151 covers
This operation removes the colon without removing the rectum and creates a continent ileostomy from the end of the small intestine. The surgeon forms an internal reservoir, commonly called a continent pouch, and brings it to the abdominal wall as a catheterizable stoma. It is performed by a colorectal or general surgeon, typically in a hospital operating room, for patients needing total colectomy who are candidates for this type of diversion.
Choose this code when the operative report supports total abdominal colectomy without proctectomy and creation of a continent ileostomy. Documentation should identify the bowel removed, confirm that the rectum was retained, and describe construction of the reservoir and stoma. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation. Modifier 50 is inappropriate for this operation, and team-surgery payment is not permitted.
