CPT® Code 38747

Abdominal lymphadenectomy, regional, including celiac, gastric, portal, peripancreatic, with or without para-aortic and vena caval nodes (List separately in addition to code for primary procedure)

Abdominal lymphadenectomy, as described by CPT® Code 38747, refers to the surgical procedure involving the regional removal of lymph nodes located in the abdominal area. This procedure is typically indicated when a malignant neoplasm has metastasized to the lymph nodes, necessitating their removal to prevent further spread of cancer. The lymph nodes targeted during this procedure include those in the celiac, gastric, portal, and peripancreatic regions, and may also involve para-aortic and vena caval nodes. The process begins with the physician identifying the affected lymph node chains, often utilizing lymph node mapping techniques to locate the sentinel node. Once the involved lymph nodes are identified, the surgeon meticulously dissects them from the surrounding tissues, ensuring the preservation of adjacent blood vessels and nerves. The excised lymph nodes are subsequently prepared for pathological examination, which is essential for determining the extent of cancer spread and guiding further treatment decisions. This procedure is reported separately in addition to the code for the primary surgical procedure performed, highlighting its significance in the overall management of cancer treatment.
