CPT code 33990 denotes the percutaneous insertion of a ventricular assist device (VAD) into the left heart via arterial access under radiologic guidance. This high-acuity interventional cardiac procedure is a key option for short-term mechanical circulatory support in patients with severe left ventricular dysfunction and can be performed in catheterization laboratories or interventional radiology suites. Nationally, the code reflects advanced cardiac care capabilities and has implications for hospital resource allocation, procedure authorization, and payer coverage policies.

Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context and typical care settings, summaries of payer coverage themes, and benchmarking information where available. The publication outlines common billing considerations and coding context for hospital-based interventional cardiac services, and it highlights areas where policy updates or prior authorization practices may affect access and reimbursement.
