Colorectal surgery
About 44156: Total colectomy with proctectomy and continent ileostomy
Reports open removal of the entire colon and rectum with creation of a continent ileostomy, typically for extensive colonic disease requiring this reconstruction.
A colorectal surgeon removes the entire colon and rectum through an abdominal operation and forms a continent ileostomy from the small bowel. The internal reservoir connects to a catheterizable abdominal stoma, allowing the patient to empty it by catheter rather than use a conventional external ileostomy appliance. This reconstruction may be performed for extensive disease such as ulcerative colitis or familial adenomatous polyposis when proctectomy and a continent diversion are planned.
Report this code when the operative record supports total colectomy, proctectomy, and creation of the continent ileostomy; a conventional end ileostomy or ileoanal reconstruction represents a different operation. The service has 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 the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How does 44156 differ from 44157 or 44158?
44157 and 44158 describe ileoanal reconstruction after proctectomy, with 44158 including creation of an ileal reservoir. Code 44156 instead creates a continent abdominal ileostomy.
What documentation supports reporting 44156?
