CPT® Code 49650

The CPT® Code 49650 refers to a laparoscopic surgical procedure specifically designed for the repair of an initial inguinal hernia. In this minimally invasive technique, a small incision is made at the umbilicus, allowing for the insertion of a laparoscope, which is a specialized instrument equipped with a camera to visualize the internal structures of the abdomen. The abdomen is then inflated with gas to create a working space for the surgeon. Following this, two or three additional small incisions are made in the abdominal wall, through which trocars are inserted. Trocars are hollow tubes that facilitate the introduction of surgical instruments into the abdominal cavity. During the procedure, the surgeon identifies the hernia and makes a peritoneal incision that extends from the lateral aspect of the inguinal canal to the lateral umbilical ligament. Key anatomical structures, such as Cooper's ligament and the inferior epigastric vessels, are exposed, and in male patients, the spermatic cord is also identified and protected. The iliac vessels are carefully located to avoid injury. The abdominal wall is then exposed, and any surrounding fatty tissue is excised to provide a clear view of the hernia sac. The hernia sac is meticulously dissected from the surrounding tissues and pushed back into the abdominal cavity. The defect in the abdominal wall is then exposed, and a mesh patch is anchored to Cooper's ligament, which is a critical support structure in the groin area. This mesh is tacked to the abdominal wall over the defect to reinforce the area and prevent future hernias. Finally, the peritoneum is closed over the abdominal wall, completely covering the mesh to ensure proper healing. After the procedure, the laparoscope, surgical instruments, and trocars are removed, and the portal incisions are closed. This procedure is specifically coded as 49650 for the initial repair of an inguinal hernia, while 49651 is designated for the repair of a recurrent inguinal hernia.
