Colon surgery
About 44144: Partial colectomy with colostomy and distal closure
Reports partial colon resection with colostomy formation and closure of the distal bowel segment in a Hartmann-type operation.
This code represents an open abdominal operation in which the surgeon removes part of the colon, brings the remaining proximal bowel out as a colostomy, and closes the downstream bowel segment. Colorectal or general surgeons may perform this configuration for conditions such as complicated diverticulitis, perforation, obstruction, or colon cancer when restoring bowel continuity is not part of the operation. The operative report should establish the extent of colon removed and how the bowel ends were managed.
Select the code from the documented procedure, not the diagnosis alone; distinguish it from other partial colectomy codes by the specific reconstruction and stoma work recorded. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

44144 billing questions
How is this code different from 44140?
44140 describes partial colectomy with anastomosis. This code describes a colostomy with closure of the distal bowel segment rather than reconnection of the bowel.
How should I distinguish this from 44143?
Both are in the Hartmann-type partial colectomy group. Use the code that matches the exact operative configuration and work documented; the diagnosis by itself does not decide between them.
Can the colostomy be billed separately?
The colostomy is part of the service represented by this code. Do not separately report it as an independent procedure when it is the stoma created as part of this colectomy.
Can modifier 50 be reported?
No. Bilateral adjustment is inappropriate for this colon procedure.
What should the operative report document?
Document the portion of colon removed, the creation of the colostomy, and closure of the distal bowel segment. These details support selection among the partial colectomy codes.
How are assistant and co-surgeon services handled?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; 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.
