CPT® Code 49255

The procedure described by CPT® Code 49255 refers to an omentectomy, also known as epiploectomy, which is a surgical operation involving the resection of the omentum. The omentum is a significant anatomical structure in the abdominal cavity, consisting of a fold of peritoneum that contains fat and extends from the stomach to various other organs. Specifically, the greater omentum stretches from the lower edge of the stomach to the transverse colon, providing a protective layer that overlies the small intestine. This procedure is typically performed through an upper midline abdominal incision, allowing the surgeon to gain access to the omentum for exploration. During the operation, the omentum is carefully examined to identify any masses, lesions, or signs of disease or injury. Once the affected segment is located, it is meticulously dissected from surrounding tissues, with blood vessels being clamped and ligated to prevent excessive bleeding. The omentum is then removed, and if necessary, drains may be placed to facilitate postoperative recovery. Finally, the abdominal incision is closed, completing the procedure.
