CPT code 32484 denotes a segmental lung resection, a surgical procedure removing a portion of lung tissue smaller than an entire lobe. This code is nationally relevant because segmental resections are key options for treating localized pulmonary disease, including early-stage malignancy and select benign conditions, offering a balance between oncologic control and preservation of lung function. Payers have distinct coverage policies and prior authorization requirements for thoracic surgical procedures, making consistent coding important for clinical and administrative teams.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for segmental lung resection, typical sites of service, common billing modifiers associated with surgical services, and how payers commonly approach authorization and reimbursement for thoracic resections. Coverage comparisons outline where policy language and documentation requirements diverge across national payers.

The publication provides benchmarks for utilization and payment trends where available, summarizes relevant policy updates affecting inpatient and outpatient settings, and highlights documentation elements frequently required by payers to support medical necessity. Data limitations are noted where input information is unavailable. The content is designed for billing managers, surgical practices, and health plan policy teams engaged in thoracic surgical care coding and reimbursement.
