Colon surgery
About 44150: Open total abdominal colectomy without proctectomy
Report this open operation when the surgeon removes the entire colon, preserves the rectum, and creates an ileostomy or ileoproctostomy.
The surgeon removes the colon through an abdominal approach while leaving the rectum in place. The reconstruction is an ileostomy or a connection from the ileum to the rectum. This operation may be performed for conditions such as ulcerative colitis or familial adenomatous polyposis when the surgical plan removes the colon but preserves the rectum. It is typically performed in a hospital operating room by a general or colorectal surgeon.
Choose the code when the operative report supports removal of the entire colon, preservation of the rectum, and one of the specified reconstructions; partial colectomy and procedures that remove the rectum belong elsewhere. The code includes the reconstruction, so do not separately report creation of the ileostomy or ileoproctostomy. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

44150 billing questions
How does this differ from a partial colectomy?
Use this code when the entire colon is removed and the rectum is preserved. A partial colectomy, such as 44140, removes less than the whole colon.
Is the ileostomy or ileoproctostomy separately reported?
No. The reconstruction is part of this colectomy service; the operative report should identify which reconstruction was performed.
When should 44151 be used instead?
44151 is for total abdominal colectomy without proctectomy when the reconstruction is a continent ileostomy. This code covers an ileostomy or ileoproctostomy.
How does rectum removal change code selection?
This code preserves the rectum. When the operation includes proctectomy, consider the total-colectomy codes that describe rectal removal and the resulting reconstruction, such as 44155 or 44156.
What documentation supports reporting this code?
The operative report should establish that the entire colon was removed, the rectum was retained, and the reconstruction was an ileostomy or ileoproctostomy.
How are assistant and co-surgeon services handled?
CMS may pay for an assistant at surgery. Co-surgeon payment requires supporting documentation; team-surgery payment 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.
