What 44147 covers
The surgeon removes a segment of colon and joins the remaining colon to the rectum low in the pelvis. The operation may include a colostomy. It is typically performed by a colorectal or general surgeon in a hospital operating room for conditions such as colorectal cancer or complicated diverticular disease when the planned resection and reconstruction require this low pelvic connection.
Report the code when the operative report supports partial colon removal and the low pelvic anastomosis; document the resection and reconstruction performed, including any colostomy. This major surgery has a 90-day global period: the day-before preoperative visit and related postoperative care during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.

44147 billing questions
How does this differ from 44145?
Both involve a low pelvic anastomosis after partial colectomy. Choose 44147 when the operative service also includes the colostomy specified for this code; 44145 describes the low pelvic anastomosis without that colostomy.
Is mobilization of the splenic flexure included?
When separately performed and documented, splenic-flexure mobilization may be reported with 44139. The operative report should support the additional mobilization.
What documentation supports reporting 44147?
Document the portion of colon removed, the low pelvic anastomosis to the rectum, and whether a colostomy was performed as part of the operation.
How does the 90-day global period affect postoperative visits?
The day-before preoperative visit and related postoperative care during the 90-day global period are included in the surgical service.
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.
