Summary & Overview
CPT 32124: Thoracotomy with Pneumonolysis
CPT code 32124 represents a thoracotomy performed with pneumonolysis — an open surgical chest incision to separate an adherent lung from the pleura. This thoracic surgical procedure is clinically significant for patients with pleural adhesions that limit lung expansion, and it carries implications for operative planning, resource use, and postoperative care across hospitals nationwide. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise interpretation of what the code covers, the typical clinical context and site of service, and which payers commonly adjudicate claims for this service. The publication also summarizes benchmark considerations, relevant coding relationships, and policy updates that affect coverage and billing practice. Where available, comparative benchmarks on utilization and reimbursement patterns are presented alongside practical notes on documentation elements that support the code assignment. Data not available in the input is noted explicitly in sections where specifics—such as associated taxonomies, ICD-10 pairings, or payer-specific reimbursement rates—are required but not provided.
Billing Code Overview
CPT code 32124 describes a thoracotomy with pneumonolysis, a surgical incision into the chest with separation of an adherent lung from the pleura. This procedure involves open surgical access to the thoracic cavity to release pleural adhesions and restore lung mobility.

Service type: Surgical, thoracic procedure
-
Typical site of service: Inpatient hospital operating room or other hospital surgical setting
Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old smoker presenting with persistent pleuritic chest pain, dyspnea, and recurrent lobar pneumonia despite antibiotics. Imaging (CT chest) demonstrates dense pleural adhesions and loculated pneumothorax with trapped lung requiring surgical intervention. The thoracic surgeon schedules a thoracotomy with pneumonolysis to gain access, separate dense pleural adhesions, and restore lung expansion. The workflow includes preoperative evaluation (history, physical, pulmonary function testing, optimization of comorbidities), informed consent, perioperative anesthesia assessment, operative thoracotomy with pneumonolysis under general anesthesia with single-lung ventilation, intraoperative hemostasis and chest tube placement, and postoperative monitoring in recovery or intensive care with chest tube management and chest radiographs to document re-expansion.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or time substantially exceeds typical for thoracotomy/pneumonolysis due to extensive adhesiolysis or unexpected complexity |
23 | Unusual anesthesia | Use when general anesthesia is deemed medically contraindicated and extraordinary anesthesia techniques are required |
