Colorectal surgery
About 44146: Partial colectomy with low pelvic anastomosis and colostomy
Open partial colon resection with a low pelvic connection to the rectum and creation of a colostomy is reported for selected colorectal conditions.
This code represents an open operation removing part of the colon, joining the remaining colon to the rectum low in the pelvis, and creating a colostomy. General or colorectal surgeons may perform it in a hospital operating room for conditions such as rectosigmoid cancer or complicated diverticular disease when resection and a low pelvic anastomosis are performed along with a colostomy. The operative report should establish the bowel removed, the low pelvic connection, and the colostomy created.
Report this code when all three elements are performed; a partial colectomy with a low pelvic anastomosis but no colostomy is a different service. The resection, anastomosis, and colostomy are represented together rather than as separate component procedures. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of 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. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
