Colorectal surgery
About 45123: Partial rectal resection
Reports surgical removal of part of the rectum when the operative service is a partial proctectomy rather than a limited lesion excision or complete proctectomy.
A partial proctectomy removes a portion of the rectum as definitive surgery. Colorectal and general surgeons typically perform it in a hospital operating room for rectal disease that requires removal of rectal tissue, such as a malignancy or another condition requiring resection. The operative report should establish the extent of rectum removed and distinguish the resection from a biopsy or localized excision of a rectal lesion.
Select this code when the documented operation is a partial proctectomy; use a more specific neighboring code when the operative details meet that code’s definition. The 90-day global period includes 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. Modifier 50 is inappropriate for this anatomy and descriptor. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

45123 billing questions
How do I distinguish this from a limited rectal lesion excision?
Use 45123 for a partial proctectomy, not a localized excision of a rectal lesion. The operative report should support removal of part of the rectum as a resection.
How does this differ from a complete proctectomy?
This code represents removal of part of the rectum. When the operation removes the rectum completely, select the applicable complete-proctectomy code instead.
Can modifier 50 be reported?
No. Modifier 50 is inappropriate for this rectal resection; report the procedure without a bilateral adjustment.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
