Summary & Overview
CPT 33990: Percutaneous Insertion of Left Ventricular Assist Device
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. Data not available in the input will be noted as such in relevant sections.
Billing Code Overview
CPT code 33990 describes the percutaneous insertion of a ventricular assist device (VAD) into the left heart using radiologic guidance. The procedure is performed by accessing the left heart via the arterial system and placing a mechanical circulatory support device to assist left ventricular function.
-
Service type: Percutaneous ventricular assist device insertion under imaging guidance
-
Typical site of service: Hospital-based interventional radiology suite or cardiac catheterization laboratory
Clinical & Coding Specifications
Clinical Context
A typical patient is a critically ill adult with advanced left ventricular failure who requires temporary percutaneous mechanical circulatory support. The patient frequently presents with acute decompensated heart failure, cardiogenic shock after myocardial infarction, or hemodynamic collapse during high-risk percutaneous coronary intervention. The interventional cardiology team evaluates vascular access suitability, reviews imaging, and obtains informed consent. In the cardiac catheterization laboratory or hybrid operating room, under fluoroscopic and radiologic guidance, the operator accesses the arterial system (commonly femoral or axillary artery), advances a catheter retrograde into the left ventricle, and deploys a percutaneous left ventricular assist device (VAD) to provide temporary circulatory support. Anticoagulation, hemodynamic monitoring, and post‑procedure ICU care are provided; device removal or conversion to durable therapy is planned based on recovery and clinical status.
