Colorectal surgery

About 45120: Complete abdominal proctectomy with colostomy

Reports complete rectal removal through an abdominal approach with colostomy, such as for rectal disease requiring resection rather than a partial proctectomy.

This operation removes the rectum completely through an abdominal approach and includes creation of a colostomy. Colorectal surgeons typically perform it in a hospital operating room for conditions such as rectal cancer when the planned operation requires complete rectal removal and a colostomy. The operative report should establish the extent of rectal resection, the abdominal approach, and the colostomy created as part of the procedure.

Choose this code when the documented operation matches those elements, rather than a partial rectal resection, a combined abdominal-perineal operation, or a reconstruction using a reservoir. The colostomy is included in the reported service. Medicare 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 multiple-procedure reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. Modifier 50 is inappropriate, and team surgery is not permitted.

Is colostomy creation included?

Yes. Colostomy creation is part of the service described by this code and should be reflected in the operative documentation.

Can an assistant surgeon be reported?

What postoperative care is included in the global period?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
