CPT code 32557 covers image-guided percutaneous placement of a small chest tube through a minimal incision to drain fluid or air from the pleural space. This procedure is a common, often urgent intervention for pleural effusion, empyema, or pneumothorax and is clinically significant for hospitals and imaging departments due to its implications for patient throughput, resource use, and post-procedure monitoring.

Key payers in the national landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage policies and payment vary by payer and by site of service; hospitals and interventional radiology units frequently bill this service in both inpatient and outpatient settings.

Readers will find practical context on clinical indications and typical settings for CPT code 32557, a summary of the payer mix addressed in the analysis, and an outline of what to expect in benchmarking and policy-related content.
