Summary & Overview

CPT 32440: Thoracotomy for Removal of Lung

CPT code 32440 represents a thoracotomy performed to remove a lung (pneumonectomy). This major thoracic surgical procedure is used for definitive treatment of extensive pulmonary disease, primary lung malignancy, or irreparable trauma. Nationally, accurate coding of 32440 is important for procedure classification, surgical quality metrics, and hospital resource planning given the complexity and inpatient nature of the service.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for thoracotomy and pneumonectomy, coding and billing considerations relevant to acute inpatient surgical care, and typical sites of service and service line placement for this procedure. The publication summarizes common modifier usage and payer-specific policy implications where available. It also outlines benchmarks and policy updates affecting coverage and inpatient authorization trends at a national level.

This analysis is intended to inform coding professionals, hospital revenue leaders, and clinical administrators about the clinical intent of CPT code 32440, how it is positioned within surgical service lines, and the payer landscape that commonly covers this high-acuity inpatient procedure.

Billing Code Overview

CPT code 32440 describes a thoracotomy with removal of a lung. This procedure involves a surgical incision into the chest wall (thoracotomy) to perform a pneumonectomy, removing an entire lung.

Service type: Surgical, thoracic surgery
Typical site of service: Inpatient operating room or surgical suite with postoperative inpatient care

Clinical & Coding Specifications

Clinical Context

A 64-year-old patient with a history of heavy tobacco use presents with progressive dyspnea and a radiographically confirmed mass occupying the right upper lobe. Tissue diagnosis confirms non-small cell lung carcinoma localized to the lung without distant metastasis. After multidisciplinary tumor board review, the thoracic surgery team schedules a formal thoracotomy and pneumonectomy to remove the entire right lung due to tumor size and central location.

The clinical workflow begins with preoperative evaluation (history, physical, pulmonary function testing, CT chest, PET as indicated, cardiology clearance), anesthesia pre-op assessment, and informed consent. On the day of surgery, the patient undergoes general endotracheal anesthesia, single-lung ventilation, and a posterolateral thoracotomy. The surgeon performs vascular control, bronchial division, and removal of the lung, with mediastinal lymph node sampling or dissection. Postoperative care includes ICU monitoring, chest tube management, pain control, respiratory therapy, and serial chest radiographs. Pathology review of the resected specimen guides adjuvant therapy decisions.
