Colorectal surgery
About 44146: Partial colectomy with low pelvic anastomosis and colostomy
Open partial colon resection with a low pelvic connection to the rectum and creation of a colostomy is reported for selected colorectal conditions.
This code represents an open operation removing part of the colon, joining the remaining colon to the rectum low in the pelvis, and creating a colostomy. General or colorectal surgeons may perform it in a hospital operating room for conditions such as rectosigmoid cancer or complicated diverticular disease when resection and a low pelvic anastomosis are performed along with a colostomy. The operative report should establish the bowel removed, the low pelvic connection, and the colostomy created.
Report this code when all three elements are performed; a partial colectomy with a low pelvic anastomosis but no colostomy is a different service. The resection, anastomosis, and colostomy are represented together rather than as separate component procedures. CMS 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 50% reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

44146 billing questions
How does this differ from 44145?
Both involve a partial colectomy with a low pelvic connection to the rectum. This code also includes creation of a colostomy; 44145 is the relevant sibling when no colostomy is created.
Can the colostomy be billed separately from this procedure?
The colostomy is part of the service represented by this code. The operative documentation should show that it was created as part of the same operation.
What should the operative report document?
Document the colon resected, the low pelvic anastomosis to the rectum, and the colostomy. Those details distinguish this service from other partial colectomy procedures.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What 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.
