CPT® Code 38780

The procedure described by CPT® Code 38780 refers to a retroperitoneal transabdominal lymphadenectomy, which is an extensive surgical operation aimed at removing lymph nodes located in the retroperitoneal space, specifically targeting pelvic, aortic, and renal nodes. This procedure is classified as a separate procedure, indicating that it is performed independently and is not part of a more extensive surgical intervention. The retroperitoneal space is an anatomical area located behind the peritoneum, which houses vital structures including the kidneys, aorta, inferior vena cava, and various lymph nodes. The lymphadenectomy is typically initiated on the same side as the malignancy, allowing for a focused approach to potentially affected lymphatic tissues. The surgical technique involves careful dissection to preserve critical anatomical structures such as the genitofemoral nerve and the psoas muscle, ensuring minimal damage to surrounding tissues. The procedure is comprehensive, involving the exploration and removal of lymph nodes from both sides of the body, and includes meticulous inspection for any signs of metastatic disease. This thorough approach is essential for accurate staging and treatment planning in patients with malignancies that may have spread to the lymphatic system.
