45113 Partial proctectomy Medicare reimbursement rates in Arkansas

A colorectal surgeon removes a portion of the rectum and creates a colostomy as part of the operative plan. The procedure is generally performed in a hospital operating room for conditions such as rectal cancer or other disease requiring resection. The operative report should make clear how much rectum was removed, the reconstruction performed, and the colostomy created.

Select this code when the documented operation matches partial rectal resection with the specified colostomy approach, rather than a more extensive complete proctectomy or a different reconstruction. Report the service for the surgeon’s operative work; documentation should support the indication, resection extent, and surgical details. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the following 90 days. 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% multiple-procedure reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
