CPT® Code 32856

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; bilateral

The procedure described by CPT® Code 32856 involves the meticulous preparation of cadaver donor lung allografts prior to transplantation, specifically for double lung transplants. This backbench standard preparation is performed on both lungs and includes a series of critical steps to ensure the allografts are suitable for transplantation. The process begins with a thorough examination of the external surface of the lungs to identify any tissue damage or abnormalities that could affect the viability of the organs. The pulmonary veins and left atrial cuff are carefully inspected for adequate length and any signs of injury, as these factors are crucial for successful anastomosis during the transplant. Additionally, the pulmonary artery is assessed for length and potential injuries, and any thrombus present is meticulously removed and sent for laboratory examination and culture to rule out infection or other complications. Following the initial assessments, the pulmonary artery is dissected free from surrounding soft tissues, allowing for proper attachment during the transplant. The bronchial staples are then removed, and specimens of bronchial secretions are collected for laboratory cultures to ensure there are no infectious agents present. The bronchus is trimmed to the appropriate length to facilitate a secure connection to the recipient's airway. Throughout this preparation, suctioning and irrigation with saline are performed as necessary to maintain a clean surgical field. Once the preparation is complete, the lungs are placed in a sterile basin, packed in ice, or bathed in cold saline to preserve their viability until the transplant team is ready to proceed with the transplantation. This comprehensive preparation is essential for the success of the double lung transplant, ensuring that both lungs are optimally prepared for implantation into the recipient.
