Colorectal surgery
About 45112: Complete proctectomy with pelvic lymphadenectomy
Reports complete rectal removal through an abdominal and perineal operation, with colostomy and pelvic lymph node dissection, commonly for rectal cancer.
This operation removes the rectum through abdominal and perineal access, creates a colostomy, and includes pelvic lymph node dissection. Colorectal or general surgeons commonly perform it in a hospital for rectal cancer requiring this extent of resection. The operative report should establish the complete rectal resection, the colostomy, and the lymph node dissection; a limited rectal resection or a procedure using a different reconstruction belongs to a different code pathway.
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 available. Co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted. Modifier 50 is inappropriate for this operation.
