CPT® Code 45402

The procedure described by CPT® Code 45402 involves a laparoscopic surgical technique known as proctopexy, which is specifically performed to address rectal prolapse. Rectal prolapse is a condition where the rectum, the final section of the large intestine, becomes displaced and protrudes through the anus. This can lead to various complications, including discomfort, difficulty with bowel movements, and potential damage to surrounding tissues. During this minimally invasive procedure, the physician utilizes a laparoscope—a thin, lighted tube equipped with a camera—to visualize the internal structures of the abdomen. Alongside the laparoscope, additional surgical instruments are inserted to facilitate the repair of the prolapse. In cases where the prolapsed section of the lower colon is also affected, the procedure may include a sigmoid resection, which involves the surgical removal of the affected portion of the sigmoid colon. This comprehensive approach aims to restore normal anatomy and function while minimizing recovery time and postoperative complications associated with traditional open surgery.
