Summary & Overview
CPT 33979: Implantable Ventricular Assist Device Insertion, Single Ventricle
Headline: CPT code 33979 — Implantable Ventricular Assist Device Insertion for Single Ventricle
Lead: CPT code 33979 identifies the surgical implantation of an implantable ventricular assist device (VAD) for patients with heart failure or severely reduced ventricular function when a single ventricle is being supported. The code captures a high-acuity cardiovascular procedure with implications for hospital resource use, device management, and post-operative care.
CPT code 33979 represents a major cardiac surgical service used in advanced heart failure management. Nationally, this procedure is significant because of its impact on inpatient surgical capacity, specialized cardiac surgery workforce requirements, and durable medical device utilization. Payors commonly covering services of this type include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn clinical context for the procedure, typical sites of service, and the types of benchmarks and policy considerations relevant to high-cost, high-complexity cardiac device implantation. The publication offers an overview of coverage considerations and common billing practices, expected service lines, and areas where policy updates and payer rules can affect authorization, payment, and post-implant care coordination. Data not available in the input for specific payer rates, ICD-10 pairings, and associated taxonomies.
Billing Code Overview
CPT code 33979 describes the surgical insertion of an implantable ventricular assist device (VAD) into a patient’s heart. This procedure is performed for patients with weakened cardiac function or heart failure and is applicable when a single ventricle is supported.
-
Service type: Implantation of an implantable ventricular assist device (surgical cardiovascular procedure)
-
Typical site of service: Inpatient hospital or specialized cardiac surgery center (operating room/bypass-capable surgical suite)
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage systolic heart failure (NYHA class IV) is evaluated for durable mechanical circulatory support. The patient has refractory symptoms despite maximal medical therapy and inotrope dependence. After multidisciplinary heart failure team review, the cardiac surgery team schedules implantation of a continuous-flow implantable ventricular assist device for left ventricular support. The procedure is performed in an operating room under general anesthesia with cardiothoracic surgical staff, perfusion team on standby, and transesophageal echocardiography for intraoperative assessment. Typical workflow includes preoperative optimization (hemodynamic monitoring, anticoagulation planning, informed consent), device implantation via median sternotomy or thoracotomy, device pump and outflow graft anastomosis to the ascending aorta, deairing, hemostasis, closure, and transfer to cardiothoracic intensive care for immediate postoperative management and device programming. Postoperative care includes anticoagulation management, infection surveillance, driveline care, and coordinated discharge planning for long-term VAD management or bridge-to-transplant evaluation.
