CPT® Code 32505

The procedure described by CPT® Code 32505 refers to a thoracotomy performed with a therapeutic wedge resection, specifically targeting a mass or nodule within the lung. A thoracotomy is a surgical procedure that involves making an incision in the chest wall to gain access to the thoracic cavity. In this case, the incision is strategically placed over the area of concern, typically at the level of the identified mass or nodule. The incision may extend around the back to facilitate better access, depending on the location of the mass. During the procedure, the surgeon dissects through the soft tissues and exposes the ribs, allowing entry into the chest cavity through the intercostal space. In some instances, a rib may be removed to enhance access to the lung tissue. Once the chest cavity is accessed, the surgeon identifies the specific section of lung tissue that contains the mass or nodule. This section is excised along with a margin of healthy lung tissue to ensure complete removal of any potentially abnormal cells. A pathology examination is performed on the excised tissue to confirm that the margins are free of abnormal tissue. If any abnormal tissue is detected at the margins, further lung tissue is removed until clear margins are achieved. To manage any air, fluid, or blood that may accumulate in the pleural space post-surgery, a temporary drainage tube may be inserted. Finally, the chest incision is closed, completing the procedure. This code is specifically used for the first wedge of lung tissue excised for therapeutic purposes, while additional resections from different sites within the same lung are reported using CPT® Code 32506.
