Colon surgery
About 44160: Open partial colectomy with ileocolic anastomosis
Reports open resection of part of the colon that includes terminal ileum, followed by reconnection of the remaining bowel through an ileocolic anastomosis.
A surgeon removes a segment of colon together with the terminal ileum and reconnects the remaining bowel. The operation is commonly performed as an open abdominal procedure for conditions such as a right-sided colon cancer or Crohn disease affecting the ileocecal region. General and colorectal surgeons typically perform it in a hospital operating room. The amount of colon removed can vary; the defining feature is the terminal ileum resection and ileocolic reconstruction.
Choose this code when the operative report supports that resection and reconstruction, rather than a partial colectomy that leaves the terminal ileum in place or a more extensive colectomy. Documentation should identify the bowel removed, the anastomosis, and the operative approach. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures occur in one 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. Modifier 50 is inappropriate, and team surgery is not permitted.

44160 billing questions
How is this distinguished from 44140?
This operation includes removal of the terminal ileum and an ileocolic anastomosis. Use 44140 for a partial colectomy with anastomosis when that terminal-ileum resection is not part of the documented procedure.
Does the code include the ileocolic anastomosis?
Yes. The anastomosis is part of the resection and reconstruction represented by this code, not a separate service to report on its own.
What operative details support code selection?
The report should identify the colon and terminal ileum removed, describe the ileocolic reconstruction, and establish that the procedure was performed through an open approach.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How does the global period affect postoperative billing?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Should modifier 50 be used for resection involving both sides of the bowel?
No. Modifier 50 is inappropriate for this code; the anatomy and procedure are not treated as a bilateral service.
