CPT® Code 32855

Backbench standard preparation of cadaver donor lung allograft prior to transplantation, including dissection of allograft from surrounding soft tissues to prepare pulmonary venous/atrial cuff, pulmonary artery, and bronchus; unilateral

The procedure described by CPT® Code 32855 involves the meticulous preparation of a cadaver donor lung allograft prior to its transplantation into a recipient. This preparation is conducted on a backbench, also known as a backtable, where the lung is carefully examined and processed to ensure its suitability for transplant. The external surface of the lung is inspected for any signs of tissue damage or abnormalities that could affect the transplant outcome. Critical components of the lung, including the pulmonary veins and the left atrial cuff, are assessed for their length and integrity, ensuring that they are free from injuries that could compromise the transplant. Additionally, the pulmonary artery undergoes a thorough examination for length and potential thrombus presence. If thrombus is detected, it is meticulously removed and sent for laboratory analysis and culture to rule out any infectious processes. The dissection process involves carefully freeing the pulmonary artery from surrounding soft tissues, which is essential for proper attachment during transplantation. The bronchial staples are removed, and specimens of bronchial secretions are collected for laboratory cultures, which are vital for identifying any potential infections. The bronchus is then trimmed to the appropriate length to facilitate a successful anastomosis during the transplant procedure. Throughout this preparation, the bronchial and lobar orifices are suctioned and irrigated with saline as necessary to maintain cleanliness and reduce the risk of contamination. Once the preparation is complete, the lung is placed in a sterile basin, packed in ice, or bathed in cold saline to preserve its viability until the transplant team is ready to proceed with the transplantation. This procedure is specifically for unilateral lung preparation, distinguishing it from the preparation of both lungs, which is covered under a different CPT® code.
