Summary & Overview
CPT 33977: Ventricular Assist Device Removal
CPT code 33977 represents the surgical removal (explantation) of a previously implanted ventricular assist device (VAD) from a single ventricle after the patient stabilizes following initial implantation. This code is used for inpatient surgical reporting and is significant for tracking high-acuity cardiac surgical care, resource utilization, and payment for advanced mechanical circulatory support services nationwide.
Key payers in the national market include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical procedure, typical sites of service, and the implications for hospital billing and surgical service lines. The publication outlines expected reporting contexts, common billing modifiers encountered in practice, and the service line implications for cardiothoracic surgery and advanced heart failure programs.
This overview provides clinical context and billing scope for hospital administrators, coding professionals, and policy analysts seeking clarity on when 33977 applies, how it fits into inpatient surgical workflows, and what to expect in payer interactions and documentation requirements. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 33977 describes the surgical removal of a previously inserted ventricular assist device (VAD) from the patient’s heart after the patient has stabilized following initial VAD placement. This procedure applies to the removal of a single ventricle assist device that had been implanted in a prior operation.
-
Service type: Surgical explantation of a ventricular assist device
-
Typical site of service: Hospital operating room or cardiac surgical suite
Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with advanced left ventricular failure was stabilized with a temporary ventricular assist device (VAD) placed emergently during cardiogenic shock. After clinical stabilization, hemodynamic improvement, and multidisciplinary team clearance, the cardiac surgery team schedules removal of the temporary VAD. The typical workflow begins with preoperative assessment in the cardiothoracic clinic or intensive care unit, review of anticoagulation and infection status, and imaging (echocardiography and chest radiograph) to confirm device position and ventricular recovery. On the day of service the patient is taken to the operating room or hybrid cardiac catheterization suite under general anesthesia. The surgeon removes the previously inserted VAD through the original access/incision, controls bleeding, inspects the cardiac repair site, and closes the wound. Postoperative care occurs in the intensive care unit with monitoring for bleeding, arrhythmia, hemodynamic stability, and wound infection. Typical sites of service are the operating room in an inpatient setting or an ambulatory surgical center when clinically appropriate. Service type: surgical removal of an implanted cardiac mechanical circulatory support device for a single ventricle.
