CPT® Code 32670

Surgical thoracoscopy, commonly known as video-assisted thoracoscopic surgery (VATS), is a minimally invasive surgical procedure used to access the thoracic cavity. In the context of CPT® Code 32670, this procedure specifically involves the surgical removal of two lobes of the right lung, a process referred to as bilobectomy. The procedure is performed through small incisions in the chest wall, allowing for reduced recovery time and less postoperative pain compared to traditional open surgery. During the procedure, single left lung ventilation is established to facilitate access and visibility within the thoracic cavity. A 1 cm portal incision is made at the 7th or 8th intercostal space in the anterior axillary line to accommodate the camera, while a second portal incision is created posteriorly at the same intercostal spaces. Additionally, a larger 4 cm access incision is made over the 3rd, 4th, or 5th interspace, depending on the specific lobes being resected. The entry into the pleural space is followed by the injection of air to induce an artificial pneumothorax, which enhances visualization of the lung and surrounding structures. The procedure includes exploration for metastatic disease, identification and ligation of pulmonary veins, and careful dissection of the lung parenchyma to ensure complete removal of the targeted lobes. This comprehensive approach aims to achieve effective surgical outcomes while minimizing trauma to the patient.
