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

What 44143 covers

The surgeon removes a diseased portion of colon, brings the upstream bowel through the abdominal wall as an end colostomy, and closes the downstream bowel segment inside the abdomen. This open operation is commonly performed for sigmoid disease, such as perforated diverticulitis or an obstructing lesion, when the surgeon does not create an immediate bowel reconnection. General and colorectal surgeons typically perform it in a hospital operating room.

Select this code when the operative report supports partial colectomy, end colostomy, and closure of the distal segment; a colostomy alone or a resection with another reconstruction is not enough. The record should identify the resection and the resulting bowel configuration. 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 reduction. Modifier 50 is inappropriate for this procedure. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
