CPT® Code 32674

Add-On Code

Thoracoscopy, surgical; with mediastinal and regional lymphadenectomy (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 32674 refers to a surgical thoracoscopy that includes the resection of mediastinal and regional lymph nodes. This procedure is typically performed in conjunction with other thoracic surgeries, such as lobectomy or pneumonectomy, particularly in patients diagnosed with malignancies affecting the lungs. The mediastinal lymph nodes are critical in assessing the extent of cancer spread, as they can indicate whether the cancer has metastasized beyond the primary tumor site. During the thoracoscopic approach, surgeons utilize specialized instruments to access the thoracic cavity through small incisions, minimizing trauma to the surrounding tissues. The procedure involves careful dissection of lymphatic tissue from adjacent structures, ensuring that all targeted nodes are completely mobilized for accurate pathological evaluation. The use of electrocautery aids in controlling bleeding during the dissection, while endoclips may be employed to secure lymphatic vessels. The entire nodal tissue is then collected and removed from the body in a contained manner, typically using an endobag, to prevent spillage of potentially cancerous cells. This meticulous approach not only aids in staging the cancer but also plays a crucial role in determining the appropriate treatment plan for the patient.
