CPT 33016: Percutaneous Pericardiocentesis with Imaging Guidance
CPT code 33016 represents percutaneous pericardiocentesis — the insertion of a needle through the chest wall into the pericardial space to aspirate or drain fluid, with imaging guidance included when performed. This procedure is clinically important for diagnosing and treating pericardial effusion, hemopericardium, and related pericardial conditions that can cause hemodynamic compromise. Nationally, accurate coding of pericardiocentesis affects acute care workflows, hospital billing, and quality measurement for cardiovascular procedural services.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes coverage nuance, bundling guidance related to imaging for needle guidance, common clinical indications, and comparator codes that may be reported in related encounters.
Readers will learn the clinical context for reporting CPT code 33016, typical sites of service, common diagnosis pairings used with the procedure, and how imaging guidance is treated for coding purposes. The review also highlights related echocardiography and ultrasound guidance codes that may appear in the clinical record and notes which imaging services are generally considered included with 33016. This summary is intended to support coding professionals, clinicians, and policy analysts seeking a concise reference to the procedure, coding relationships, and payer coverage scope at a national level.

National Reimbursement Benchmarks
Medicare reimbursement for CPT 33016 centers around a mean of $204.50, substantially lower than BUCA’s commercial average of $629.40—a difference of $424.90 that highlights a meaningful gap between federal and commercial pricing for this service. This gap reflects Medicare’s lower average relative to a commercial aggregator and helps contextualize where commercial rates sit versus government payment levels.
