CPT code 44150: Total colectomy, rectum retained; ileostomy or ileoproctostomy2026 Medicare rate & RVUs

Medicare pays $1,730.50 for 44150 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 44150 covers

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.
