CPT® Code 32602

The procedure described by CPT® Code 32602 is known as diagnostic thoracoscopy, which may also be referred to as pleuroscopy. This minimally invasive procedure is performed to examine the lungs and pleural space for any abnormalities. During thoracoscopy, various techniques can be utilized to gain access to the pleural cavity. One common method involves blunt entry, where a clamp is passed over a rib and through the pleura, allowing for direct inspection of the pleural space to ensure there is sufficient room for the insertion of the thoracoscope. Once the scope is inserted under direct vision, the pleura and lung are thoroughly inspected, and any abnormalities are documented. In some cases, fluid may be evacuated from the pleural space using suction catheters to facilitate a clearer view. Another technique involves making a small intercostal incision in the chest wall, through which a trocar is inserted into the intercostal space, the area between two ribs. After entering the pleural space, air is injected to induce an artificial pneumothorax, which enhances visualization of the lung and pleura. An endoscope is then introduced through the trocar for a detailed examination. While diagnostic procedures are often conducted through a single incision, additional small incisions may be made to introduce other surgical instruments as needed. During the procedure, any fluid present in the chest is drained, and the lung and pleura are inspected again for abnormalities, which may include photographing lesions for further analysis. Upon completion of the examination, the thoracoscope is withdrawn, air is evacuated from the pleural space, and a chest tube is typically placed to ensure proper drainage. If a biopsy of the lung or pleura is performed, specific tools such as cusp forceps or a surgical stapling device are utilized to obtain tissue samples for further evaluation.
