Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The procedure described by CPT® Code 32856 is indicated for patients requiring a double lung transplant. The specific indications for this procedure include:

  • End-stage lung disease Patients suffering from conditions such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, or cystic fibrosis may require a double lung transplant due to the irreversible decline in lung function.
  • Severe pulmonary hypertension Individuals with severe pulmonary hypertension that is unresponsive to medical therapy may be candidates for a double lung transplant to improve their quality of life and survival.
  • Acute respiratory failure Patients experiencing acute respiratory failure due to various causes, including trauma or severe infections, may necessitate a double lung transplant as a life-saving intervention.

2. Procedure

The procedure for the backbench standard preparation of cadaver donor lung allografts prior to transplantation involves several critical steps:

  • Examination of the lung The external surface of the cadaver donor lung is thoroughly examined for any signs of tissue damage or abnormalities that could compromise the transplant.
  • Inspection of pulmonary veins and left atrial cuff The pulmonary veins and left atrial cuff are inspected for adequate length and any injuries. This assessment is crucial for ensuring proper anastomosis during the transplant.
  • Assessment of the pulmonary artery The pulmonary artery is checked for length and any injuries. If thrombus is present, it is carefully removed and sent for laboratory examination and culture.
  • Dissection of the pulmonary artery The pulmonary artery is then dissected free from surrounding soft tissues to facilitate its connection to the recipient's circulatory system.
  • Removal of bronchial staples The bronchial staples are removed, and specimens of bronchial secretions are collected for laboratory cultures to ensure the absence of infectious agents.
  • Trimming of the bronchus The bronchus is trimmed to the desired length to ensure a secure connection to the recipient's airway during transplantation.
  • Suctioning and irrigation The bronchial and lobar orifices are suctioned and irrigated with saline as needed to maintain a clean surgical field.
  • Preparation for transplantation Once all preparations are complete, the lungs are placed in a sterile basin and packed in ice or bathed in cold saline until the transplant team is ready to begin the transplant procedure.
  • Additional steps for double lung transplant In a double lung transplant, the attached pericardium may need to be excised, and the posterior wall of the left atrium is divided between the left and right pulmonary veins. Non-vascular staples are placed along the bronchial-carinal junction of the first lung to be transplanted, and the main bronchus is divided distal to the staple line. The first lung is prepared and delivered to the transplant recipient team, while the second lung is prepared in the same manner and delivered subsequently.

3. Post-Procedure

Post-procedure care following the backbench preparation of cadaver donor lung allografts involves monitoring the allografts for viability and ensuring that they remain in optimal condition until transplantation. The lungs must be kept in a sterile environment and maintained at appropriate temperatures to preserve their function. The transplant team will also prepare for the surgical implantation of the lungs into the recipient, ensuring that all necessary equipment and personnel are ready for the procedure. Continuous communication between the preparation team and the transplant team is essential to coordinate the timing of the transplant and ensure a smooth transition from preparation to implantation.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
GC This service has been performed in part by a resident under the direction of a teaching physician
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
