CPT® Code 49595

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); greater than 10 cm, reducible

The CPT® Code 49595 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 49595 is designated for the repair of a reducible hernia, which is characterized by a defect greater than 10 cm in length. A reducible hernia means that the contents of the hernia sac can be pushed back into their normal position within the abdomen. During the repair process, large defects may require the use of a shoelace technique and often necessitate reinforcement with a mesh implant to prevent recurrence. The procedure begins with an incision made over the hernia defect for open repairs, or a small incision is created near the defect for laparoscopic approaches, where a trocar is inserted, and pneumoperitoneum is established to facilitate the introduction of a laparoscope. Additional incisions may be made to allow for the insertion of surgical instruments or robotic tools. The surgical team will first excise any existing scar tissue, dissecting the skin and fat away from the hernia sac. Any adherent omentum or bowel is carefully separated from the hernia sac and freed from the abdominal wall. The hernia sac, along with its peritoneal lining and any scar tissue or suture material, is excised. Following the reduction of the hernia, the closure of the defect may involve reconstructing the linea alba, which is a fibrous structure in the midline of the abdomen. This reconstruction is achieved by suturing the anterior rectus muscle strips together, ensuring that the lateral edges of the rectus sheaths meet at the midline and are anchored to the newly formed linea alba. If the abdominal contents have protruded through the anterior rectus or transversus abdominis and internal oblique muscles, the hernia sac is opened, inspected, and any healthy contents are returned to the abdominal cavity. The procedure concludes with the closure of the defect openings in the fascia and the placement of mesh or a prosthetic implant, which is typically performed to minimize the risk of recurrence. Various techniques, such as underlay, onlay, inlay, wrap-around, or a combination of these, may be employed for the mesh placement, which is cut to the appropriate shape to reinforce the hernia repair. It is important to note that if the repair necessitates the removal of any existing fractured, brittle, or aged mesh, this must be reported separately. For cases involving strangulated or incarcerated hernias greater than 10 cm, where the contents cannot be returned to their normal position and circulation is compromised, the appropriate code to use is 49596.
