CPT 32853 Bilateral Lung Transplant Reimbursement | OpenPayer

Summary & Overview

CPT 32853: Bilateral Lung Transplant Without Cardiopulmonary Bypass

CPT code 32853 denotes a bilateral lung transplant performed without cardiopulmonary bypass, replacing both lungs with donor organs. This high-complexity surgical code captures one of the most resource-intensive thoracic procedures performed at specialized transplant centers. Nationally, accurate coding for bilateral lung transplantation affects hospital case mix, reimbursement pathways, and quality reporting for transplant programs.

Key payers commonly involved in coverage and payment for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, payer coverage patterns, and the types of benchmarks and policy topics typically associated with lung transplant billing and reimbursement. The analysis also highlights common documentation elements and service-line implications for inpatient surgical and intensive post-operative care.

This publication is intended to provide a clear, practical reference for billing staff, revenue cycle leaders, and policymakers seeking a national perspective on coding, payer considerations, and the clinical setting tied to CPT code 32853.

Billing Code Overview

CPT code 32853 describes a surgical procedure in which the provider performs a bilateral lung transplant without the use of cardiopulmonary bypass, replacing both diseased lungs with healthy lungs from a cadaveric or living donor. This is a major thoracic surgical intervention focused on organ replacement.

Service type: Surgical — bilateral lung transplantation without cardiopulmonary bypass
Typical site of service: Inpatient hospital setting, performed in an operating room with post-operative intensive care and transplant unit care

Clinical & Coding Specifications

Clinical Context

A 48-year-old patient with end-stage pulmonary fibrosis is evaluated for bilateral lung transplantation. The patient has progressive hypoxemic respiratory failure despite maximal medical therapy, recurrent hospitalizations for respiratory decompensation, and meets transplant center criteria. Preoperative workup includes pulmonary function testing, high-resolution chest CT, right heart catheterization, infectious disease screening, psychosocial evaluation, and multidisciplinary transplant committee approval. On the day of surgery the patient is brought to the operating room, under general anesthesia, and undergoes a bilateral lung transplant without the use of cardiopulmonary bypass. Intraoperative steps include native lung pneumonectomy, implantation of donor lungs sequentially, airway anastomoses, pulmonary artery and left atrial cuff anastomoses, and intraoperative bronchoscopy to assess anastomotic integrity. Postoperative care includes mechanical ventilation in the intensive care unit, immunosuppression initiation, hemodynamic monitoring, chest tube management, serial bronchoscopies for airway clearance and biopsy surveillance, and early mobilization. Typical sites of service are an acute-care hospital operating room and cardiothoracic surgical intensive care unit. This procedure is typically performed by thoracic and cardiothoracic transplant surgeons with multidisciplinary support from pulmonology, anesthesia, perfusion (if needed), and critical care teams.
