What 44316 covers
This operation creates an internal reservoir from small bowel and forms a continent outlet at the abdominal wall. The patient empties the pouch by passing a catheter through the stoma rather than collecting output continuously in an external ostomy appliance. A colorectal or general surgeon may perform it for a patient requiring ileal diversion, including selected patients after colectomy for ulcerative colitis or familial adenomatous polyposis. The operative report should identify the reservoir and continent outlet being constructed.
Report 44316 when the continent ileostomy construction is the service represented, rather than a conventional ileostomy. When the surgeon performs it as part of a comprehensive colectomy that includes a continent ileostomy, use the applicable colectomy code instead of separately reporting the pouch construction. This major surgery has a 90-day global period, including the day-before preoperative visit and related postoperative care. For other procedures in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
