CPT® Code 32601

Thoracoscopy, as defined by CPT® Code 32601, is a diagnostic procedure that allows for the examination of the lungs, pericardial sac, mediastinal, or pleural space without the need for a biopsy. This procedure employs various techniques to gain access to the thoracic cavity, enabling healthcare professionals to visually inspect the pleura and lungs for any abnormalities. One common method involves blunt entry, where a clamp is passed over a rib and through the pleura, allowing for direct visualization of the pleural space. This ensures that there is adequate space for the insertion of the thoracoscope, which is then introduced under direct vision. The thoracoscope facilitates a thorough inspection of the pleura and lung, where any irregularities can be noted, and fluid can be evacuated using suction catheters if necessary. Another technique may involve making a small intercostal incision to insert a trocar into the intercostal space, which is the area between two ribs. This method may induce an artificial pneumothorax by injecting air into the pleural space, enhancing the visualization of the lung and pleura. The thoracoscope is then inserted through the trocar, allowing for a detailed examination. While diagnostic procedures are often performed through a single incision, additional small incisions may be made to introduce other surgical instruments as needed. In cases where the mediastinum or pericardial sac requires evaluation, the thoracoscope can be introduced at the right or left midaxillary line and the sixth or seventh intercostal space. Alternatively, for mediastinal disease assessment, a port may be placed in the subxiphoid region for access. During the procedure, the mediastinum or pericardial sac is visualized, and any abnormalities are documented. If the mediastinal space is being evaluated, structures such as the carina, main bronchi, and lymph nodes are examined. For pericardial sac evaluation, an incision is made in the pericardium to aspirate fluid for laboratory analysis, while the cardiac chambers, epicardium, and pericardium are inspected for lesions or implants. Throughout the procedure, photographs may be taken to document findings. Upon completion, the thoracoscope is withdrawn, air is evacuated from the pleural space, and a chest tube is placed to facilitate drainage if necessary.
