CPT® Code 32850

The procedure described by CPT® Code 32850 refers to a donor pneumonectomy, which involves the surgical removal of one or both lungs from a cadaver donor, specifically a brain-dead patient. This complex operation is performed to prepare the lungs for transplantation into a recipient. The process begins with the careful removal of the lungs, which are typically extracted en bloc with the heart, meaning both organs are taken together as a single unit. A significant incision is made in the chest to access the thoracic cavity, allowing the surgeon to open the thorax and gain visibility and access to the vital structures within. During the procedure, the great vessels, including the aorta and the vena cavae, as well as the trachea, are meticulously dissected free from the surrounding tissues to ensure a clean removal. To prevent clotting during the surgery, systemic heparin, an anticoagulant, is administered. The pulmonary arteries are then cannulated, which involves inserting a tube into the arteries to facilitate the flushing of the pulmonary vasculature with a cold preservation solution. This step is crucial as it helps to preserve the lung tissue for transplantation. As the procedure progresses, the heart and respiration of the donor are intentionally stopped. The surgeon then divides the superior and inferior vena cava, the aorta, and the trachea, allowing for the complete removal of the heart and lung block. Following this, the heart is separated from the lungs, along with the attached portions of the superior and inferior vena cavae and the aorta. In some cases, the lungs may also be separated from each other. Once harvested, the lungs are placed in a crystalloid solution, packed in ice, and transported to the recipient transplant site, ensuring they remain viable for transplantation. This detailed and intricate procedure is essential for facilitating successful lung transplants, ultimately aiming to save the lives of patients in need of lung replacement.
