Official Description

Replacement of ventricular assist device pump(s); implantable intracorporeal, single ventricle, without cardiopulmonary bypass

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 33982 refers to the replacement of a ventricular assist device (VAD) pump that is implantable and intracorporeal, specifically designed for a single ventricle, and performed without the use of cardiopulmonary bypass. A ventricular assist device is a mechanical pump that supports heart function and blood flow in individuals with weakened hearts. The device is implanted within the body, allowing for a more natural integration with the patient's physiology. The procedure involves a surgical approach where a midline chest incision is made, extending into the upper abdomen to access the pump pocket. This replacement procedure is typically necessary when the existing pump experiences mechanical failure, necessitating its removal and substitution with a new pump. The process is intricate, requiring careful dissection and connection of various conduits and lines to ensure proper functionality of the new device. The absence of cardiopulmonary bypass during this procedure indicates that the heart is not temporarily stopped, allowing for a more straightforward surgical approach and potentially reducing recovery time for the patient.

1. Indications

The replacement of a ventricular assist device pump using CPT® Code 33982 is indicated for patients who require a new pump due to mechanical failure of the existing device. This procedure is typically performed in individuals with a single ventricle heart condition who are dependent on the VAD for adequate blood circulation and cardiac support. The need for replacement may arise from various complications associated with the device, such as pump malfunction or wear over time.

  • Mechanical Failure Replacement is indicated when the existing VAD pump has failed to function properly.
  • Single Ventricle Heart Condition Patients with a single ventricle anatomy who rely on the VAD for hemodynamic support.

2. Procedure

The procedure for replacing the ventricular assist device pump involves several critical steps to ensure successful implantation and functionality of the new device.

  • Step 1: Incision A midline chest incision is made and extended into the upper abdomen to provide access to the pump pocket.
  • Step 2: Pump Pocket Access The pump pocket in the upper abdomen is opened to facilitate the removal of the existing pump.
  • Step 3: Cardiopulmonary Bypass Consideration If cardiopulmonary bypass is required, it is initiated at this stage; however, for this specific code, it is performed without bypass.
  • Step 4: Inspection of Insertion Site The anterior surface of the heart insertion site for the VAD cannula is inspected to ensure there are no complications.
  • Step 5: Drive Line Management The drive line is located, inspected, and repaired or replaced as necessary to maintain device integrity.
  • Step 6: Conduit Dissection The inflow and outflow conduits are carefully dissected and separated from the pump housing to prepare for pump removal.
  • Step 7: Pump Removal The existing pump is meticulously dissected free from surrounding tissue and removed from the body.
  • Step 8: New Drive Line Tunnel Creation A new drive line tunnel is created as needed, extending from the thoracic cavity to the abdominal pocket for the new pump.
  • Step 9: New Pump Placement A new pump is placed in the abdominal pocket and connected to the inflow and outflow conduits to restore functionality.
  • Step 10: Drive Line Connection The drive line is connected to the new pump, ensuring proper electrical and mechanical integration.
  • Step 11: Reperfusion and Air Removal If cardiopulmonary bypass was used, the heart is reperfused, and cardioplegia is reversed. Air is removed from the VAD, and the new pump is activated.
  • Step 12: Function Evaluation The function of the new pump is evaluated to ensure it is operating correctly.
  • Step 13: Hemostasis Check Suture sites are checked for hemostasis to prevent postoperative bleeding.
  • Step 14: Pacing Wires and Drains Pacing wires are placed on the heart, and chest tubes are inserted to manage any potential fluid accumulation.
  • Step 15: Incision Closure Finally, the chest and abdominal incisions are closed to complete the procedure.

3. Post-Procedure

Post-procedure care following the replacement of a ventricular assist device pump includes monitoring the patient for any signs of complications, such as bleeding or infection at the incision sites. Patients are typically observed in a recovery area where vital signs are closely monitored. The function of the new pump is assessed regularly to ensure it is operating effectively. Patients may require additional imaging or tests to confirm the proper placement and function of the device. Pain management and rehabilitation may also be part of the recovery process, as patients adjust to the new pump and its integration into their cardiovascular system. Follow-up appointments are essential to evaluate the long-term success of the procedure and the overall health of the patient.
