Summary & Overview
CPT 32672: Lung Volume Reduction Surgery, Thoracic Procedure
CPT code 32672 represents a thoracic surgical procedure for lung volume reduction in patients with severe emphysema. The operation visualizes the chest cavity and removes about 30% of poorly functioning lung tissue to improve respiratory mechanics. This code matters nationally because lung volume reduction surgery is a specialized, resource-intensive intervention with implications for surgical capacity, hospital resource use, and payer coverage policies for advanced COPD and emphysema care.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent and typical setting for CPT code 32672, comparisons of coverage and utilization benchmarks among major payers, and context on billing and service-line implications for thoracic surgery programs. The publication highlights service delivery considerations, expected site-of-service patterns (inpatient hospital or ambulatory surgical center operating rooms), and common billing modifiers encountered in practice.

Billing Code Overview
CPT code 32672 describes a surgical procedure to visualize the chest cavity and remove emphysematous sections of lung tissue. The procedure involves identifying and excising approximately 30% of poorly functioning lung to achieve lung volume reduction in patients with advanced emphysema.
Service Type: Surgical lung volume reduction, thoracic operative procedure
Typical Site of Service: Inpatient hospital or ambulatory surgical center (operating room/thoracic surgery suite)
Clinical & Coding Specifications
Clinical Context
A typical patient is a sixty-year-old current or former heavy smoker with severe, heterogeneous emphysema who presents with progressive dyspnea, impaired exercise tolerance, and frequent exacerbations despite optimized medical therapy (bronchodilators, inhaled corticosteroids as indicated, pulmonary rehabilitation, and smoking cessation). Preoperative evaluation includes pulmonary function testing (reduced FEV1, increased residual volume), high-resolution CT chest demonstrating upper-lobe–predominant emphysematous destruction with relatively preserved interlobar septae, arterial blood gases, cardiopulmonary exercise testing if needed, and multidisciplinary review by thoracic surgery and pulmonology.
The clinical workflow: the patient is admitted to an operating room or an ambulatory surgery center that supports thoracic procedures and general anesthesia. Under general endotracheal anesthesia with single-lung ventilation, the thoracic surgeon performs a thoracoscopic lung volume reduction procedure to resect approximately 30% of the most emphysematous, nonfunctional lung tissue. Intraoperative documentation includes informed consent, anesthesia record, laterality, estimated percent lung removed, specimens submitted if applicable, and perioperative complications. Postoperatively the patient is monitored in a post-anesthesia care unit or inpatient ward, with attention to chest tube management, pulmonary toilet, and early ambulation. Discharge planning includes pulmonary rehabilitation, outpatient follow‑up with thoracic surgery and pulmonology, and home oxygen assessment if required.
