CPT® Code 44143

The procedure described by CPT® Code 44143 refers to a partial colectomy, which involves the surgical removal of a segment of the colon, specifically performed with the creation of an end colostomy and the closure of the distal segment. In simpler terms, this means that a portion of the large intestine is excised through a midline incision in the abdomen. The distal end of the bowel, which is the segment that remains after the diseased or damaged portion is removed, is sutured closed, creating what is known as a Hartmann pouch. This type of procedure is particularly relevant when the distal segment of the bowel and the rectum are preserved rather than removed. The end colostomy is established using the sigmoid colon, which is the lower segment of the bowel. This is done by making a small incision in the skin at the site where the colostomy will be created, followed by careful dissection through the subcutaneous tissue and fascia to access the colon. The procedure requires meticulous attention to the blood supply of the colon and surrounding structures to ensure proper healing and function post-surgery. The colon is then brought through the abdominal wall, everted, and sutured to the skin, allowing for the diversion of fecal matter into a colostomy bag. This procedure is typically indicated in cases where there is significant disease or damage to the colon that necessitates removal while still allowing for some bowel continuity through the Hartmann pouch.
