CPT® Code 32440

The CPT® Code 32440 refers to the surgical procedure known as pneumonectomy, which involves the complete removal of a lung. This procedure is typically indicated for patients with severe lung conditions, such as lung cancer, that necessitate the removal of an entire lung to prevent the spread of disease or to alleviate significant respiratory issues. The operation is performed through a posterolateral thoracic incision, which is strategically made in the intercostal space, starting just below the shoulder blade and extending around to the front of the chest. In some cases, to enhance access to the lung, a rib may be removed during the procedure. Once access is achieved, the lung is deflated, and the major blood vessels supplying the lung are carefully ligated and divided to prevent excessive bleeding. The main bronchus, which is the airway leading to the lung, is then clamped and incised, allowing for the complete removal of the lung. After the lung is excised, the remaining segment of the bronchus is either stapled or sutured closed to ensure proper healing. Following the removal, a chest tube is placed to facilitate drainage and prevent fluid accumulation, and the chest incision is subsequently closed. This procedure is critical in managing advanced pulmonary diseases and requires careful consideration of the patient's overall health and specific medical conditions.
