Colorectal surgery

About 45111: Partial abdominal proctectomy with anastomosis

Reports abdominal removal of part of the rectum with bowel reconnection, typically for rectal disease when the operative plan includes an anastomosis.

A colorectal surgeon removes a segment of rectum through an abdominal approach and reconnects the remaining bowel with an anastomosis. The operation may be performed for rectal cancer or selected benign disease when the surgical plan preserves bowel for reconstruction. It is generally performed in a hospital or other facility setting. This code represents a segmental rectal resection with reconnection, not a limited transanal excision of a rectal lesion.

Select the code from the operative report, which should support the partial resection, abdominal approach, and anastomosis. 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 others at 50%. Modifier 50 is inappropriate for this anatomy. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

45111 billing questions

How is this code distinguished from complete proctectomy?

This code describes removal of part of the rectum with an anastomosis through an abdominal approach. A complete rectal removal is represented by a different proctectomy code.

Can a transanal rectal tumor excision be reported instead?

Use a transanal excision code when the surgeon removes a localized tumor through the anus rather than performing an abdominal segmental rectal resection with anastomosis.

What operative details support reporting this code?

The operative report should establish that part of the rectum was removed through an abdominal approach and that the bowel was reconnected with an anastomosis.

Does the code include postoperative visits?

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

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures subject to the standard multiple procedure reduction are paid at 50%.

May 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.
