CPT 31634 Bronchoscopic Balloon Occlusion Reimbursement | OpenPayer

Summary & Overview

CPT 31634: Bronchoscopic Balloon Occlusion for Pulmonary Air Leak

CPT code 31634 denotes bronchoscopic placement and inflation of a balloon in the lung to identify and treat air leaks, with optional instillation of an occlusive agent and possible fluoroscopic guidance. This targeted therapeutic procedure addresses persistent pulmonary air leaks that can complicate thoracic surgery, trauma, or chronic lung disease and is significant for hospitals and procedural centers managing complex pulmonary patients. Nationally, the procedure matters for inpatient care pathways, resource utilization in thoracic surgery and pulmonary services, and payer coverage decisions for advanced bronchoscopic interventions.

Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of billing and clinical context for 31634, typical sites of service, common payer considerations, and the types of benchmarks and policy issues that influence coding, coverage, and reimbursement for bronchoscopic air-leak interventions. The publication also summarizes clinical indications and procedural elements relevant to documentation and claims submission. Data not available in the input for associated taxonomies, ICD-10 diagnoses, related codes, and detailed payer-specific policy limits is noted where applicable.

Billing Code Overview

CPT code 31634 describes bronchoscopic placement of a balloon in the lung with inflation to assess and treat an air leak; the procedure may include instillation of an occlusive substance to permanently seal the leak and may use fluoroscopic guidance. This procedure is performed using a rigid or flexible bronchoscope.

Service type: Therapeutic bronchoscopic procedure for air-leak management
Typical site of service: Hospital inpatient or outpatient operating room or procedural suite, and outpatient ambulatory surgery centers when clinically appropriate

Clinical & Coding Specifications

Clinical Context

A 62-year-old male with a persistent alveolar air leak following lobectomy for lung cancer is brought to the bronchoscopy suite. Prior chest tube drainage has failed to resolve the pneumothorax and prolonged air leak. The interventional pulmonologist performs bronchoscopic balloon occlusion to localize the bronchopleural fistula, assesses for residual air leak, and, if needed, deploys an occlusive agent or device to seal the leak. The procedure may be performed under conscious sedation or general anesthesia with endotracheal intubation, and fluoroscopic guidance is used when deploying occlusive material or confirming balloon position. The workflow includes pre-procedure consent and imaging review, airway inspection with flexible or rigid bronchoscopy, selective balloon inflation to isolate culprit airways, leak assessment via chest tube monitoring or saline instillation, application of occlusive substance (e.g., endobronchial valve, sealant, or glue) if indicated, post-procedure chest radiograph and chest tube management, and discharge instructions with follow-up imaging and pulmonary clinic review.
