Colorectal surgery
About 44156: Total colectomy with proctectomy and continent ileostomy
Reports open removal of the entire colon and rectum with creation of a continent ileostomy, typically for extensive colonic disease requiring this reconstruction.
A colorectal surgeon removes the entire colon and rectum through an abdominal operation and forms a continent ileostomy from the small bowel. The internal reservoir connects to a catheterizable abdominal stoma, allowing the patient to empty it by catheter rather than use a conventional external ileostomy appliance. This reconstruction may be performed for extensive disease such as ulcerative colitis or familial adenomatous polyposis when proctectomy and a continent diversion are planned.
Report this code when the operative record supports total colectomy, proctectomy, and creation of the continent ileostomy; a conventional end ileostomy or ileoanal reconstruction represents a different operation. The service has 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 the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

Both describe a continent ileostomy with total colectomy, but 44151 does not include proctectomy. The operative report must establish whether the rectum was removed.
44157 describes ileoanal anastomosis after total colectomy and proctectomy. Use 44156 when the reconstruction is a continent ileostomy through an abdominal stoma.
44158 includes an ileal reservoir for ileoanal reconstruction; 44156 creates a continent abdominal ileostomy rather than an ileoanal connection.

44156 billing questions
How does this differ from 44155?
Both include total colectomy and proctectomy. Code 44156 includes creation of a continent ileostomy; 44155 describes a conventional ileostomy.
When is 44151 a closer match?
44151 describes total colectomy with a continent ileostomy without proctectomy. Use 44156 when the rectum is also removed.
Does this code include the continent ileostomy?
Yes. Creation of the continent ileostomy is part of the operation represented by this code, alongside total colectomy and proctectomy.
How does 44156 differ from 44157 or 44158?
44157 and 44158 describe ileoanal reconstruction after proctectomy, with 44158 including creation of an ileal reservoir. Code 44156 instead creates a continent abdominal ileostomy.
What documentation supports reporting 44156?
The operative report should establish removal of the entire colon and rectum and formation of a continent, catheterizable ileostomy. It should distinguish this reconstruction from a conventional ileostomy or ileoanal connection.
How are other same-session procedures and surgical assistants handled?
Under the CMS multiple-procedure rule, the highest-valued procedure is paid in full and other procedures at 50%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
