CPT® Code 49591

Repair of anterior abdominal hernia(s) (ie, epigastric, incisional, ventral, umbilical, spigelian), any approach (ie, open, laparoscopic, robotic), initial, including implantation of mesh or other prosthesis when performed, total length of defect(s); less than 3 cm, reducible

The CPT® Code 49591 refers to the initial repair of anterior abdominal hernias, which include types such as epigastric, incisional, ventral, umbilical, and spigelian hernias. This procedure can be performed using various approaches, including open surgery, laparoscopic techniques, or robotic assistance. An anterior abdominal hernia occurs when tissue or parts of an organ, such as the intestines, protrude through a defect in the abdominal wall. The specific code 49591 is designated for the repair of a reducible hernia, which is defined as a hernia that can be pushed back into its normal position within the abdomen. The size of the defect in this case is less than 3 cm. During the repair process, the surgeon may make an incision directly over the hernia defect for open repairs, or utilize a laparoscopic approach, which involves making a small incision near the defect and inserting a trocar to establish pneumoperitoneum for the introduction of a laparoscope. Additional incisions may be made to allow for the insertion of surgical instruments or robotic tools. The procedure typically begins with the excision of any existing scar tissue surrounding the hernia sac, followed by the dissection of the skin on either side of the defect to fully expose the hernia sac. The contents of the hernia sac, which may include omentum and bowel, are carefully dissected away from the inner surface of the sac and freed from the abdominal wall. The hernia sac, along with its peritoneal lining and any scar tissue or previous sutures, is excised. For incisional hernias, the normal tissue of the linea alba is usually exposed, and the abdominal wall is sutured closed. If the hernia involves protrusion through the anterior rectus or transversus abdominis and internal oblique muscles, the sac is opened and inspected, with healthy contents being returned to the abdominal cavity. Any adhesions are also dissected free, and the defect in the fascia is closed. To minimize the risk of recurrence, mesh may be implanted during the repair. It is important to note that if the repair necessitates the removal of any existing mesh that is fractured or aged, this procedure is reported separately. For cases involving strangulated or incarcerated hernias, which cannot be reduced and may compromise circulation, a different code (49592) is utilized.
