Colorectal surgery
About 44155: Total colectomy with proctectomy and ileostomy
Reports open removal of the colon and rectum with creation of an ileostomy, commonly for extensive colorectal disease when intestinal continuity is not restored.
This code describes an abdominal operation removing the colon and rectum and creating an ileostomy, rather than connecting the remaining small bowel to the anus. Colorectal or general surgeons may perform it in a hospital for conditions such as severe ulcerative colitis, familial adenomatous polyposis, or colorectal disease requiring removal of both organs. The ileostomy provides the route for intestinal waste after the resection.
Report the code when the operative record supports total colectomy, proctectomy, and ileostomy creation as part of the same operation. Documentation should identify the organs removed and the reconstruction performed; an ileoanal anastomosis or pouch points to a different code. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation. Team surgery is not permitted.

44155 billing questions
How is this different from 44150?
44150 describes total abdominal colectomy without proctectomy. Use 44155 when the operation also removes the rectum and creates an ileostomy.
When would 44151 be the better choice?
44151 describes total colectomy without proctectomy with a continent ileostomy. This code describes proctectomy with ileostomy creation, not a continent reservoir.
Can an ileoanal anastomosis be reported with 44155?
No. An ileoanal reconstruction is a distinguishing feature of codes such as 44156 through 44158; 44155 describes an ileostomy.
What supports reporting 44155?
The operative report should document removal of the colon and rectum and creation of an ileostomy. It should distinguish this reconstruction from an ileoanal anastomosis or pouch.
How do the global period and assistant rules affect billing?
The 90-day global includes the day-before preoperative visit and related postoperative care. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation.
Should modifier 50 be used?
No. Modifier 50 is inappropriate for this operation; report the procedure based on the documented resection and reconstruction.
