CPT® Code 38381

The procedure described by CPT® Code 38381 involves the suture and/or ligation of the thoracic duct through a thoracic approach. The thoracic duct is a critical component of the lymphatic system, serving as the primary channel for lymph fluid, which is essential for immune function and fluid balance in the body. It typically originates in the abdomen at the cisterna chyli, located near the second lumbar vertebra, and ascends through the thoracic cavity, crossing from the right side to the left at the level of the fourth or fifth thoracic vertebra before draining into the left jugular-subclavian venous junction. Due to its delicate structure, the thoracic duct is vulnerable to injury, which can result in lymphatic leaks. This procedure is performed to repair such leaks, which may occur due to surgical trauma or other injuries. The surgical approach is determined by the location of the injury, and the procedure involves careful dissection to expose the duct, locate the site of the leak, and perform the necessary repairs using sutures or ligation. Following the repair, additional measures, such as the placement of gauze pads and chest tubes, are taken to ensure proper healing and to monitor for any further leakage.
