45110 Rectal resection Medicare reimbursement rates in Oregon

This operation removes the rectum through both abdominal and perineal access and includes creation of a colostomy. Colorectal and general surgeons commonly perform it in a hospital operating room, often for rectal cancer when a restorative reconstruction is not planned. The operative report should establish the full extent of rectal removal, both approaches, and the colostomy.

Select this code when the documented operation matches that complete resection and colostomy combination, rather than a partial resection or a different operative approach. It has a 90-day global period that includes the day-before preoperative visit and related postoperative care during the following 90 days. For procedures performed in the same session, Medicare pays the highest-valued procedure in full and reduces other procedures under the standard multiple-procedure rule. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is not appropriate for this single-organ procedure.
