2025 CPT code 33979

Insertion of implantable ventricular assist device (VAD), intracorporeal, single ventricle.

Use code 33979 for single ventricle support. For biventricular support, use 33976 (extracorporeal) or other appropriate codes based on the device and approach.

Modifiers may be applicable in specific circumstances (e.g., 59 for distinct procedural services). Refer to current CPT guidelines for modifier usage.

Medical necessity is established by documentation of severe heart failure refractory to medical management, as a bridge to transplant, or for temporary support during cardiac surgery.

The surgeon prepares the patient, makes an incision, creates a pocket for the VAD, connects the device to the heart, and ensures proper functioning before closing the incision.

IMPORTANT Related codes for VAD procedures include 33975, 33976, 33977, 33978, 33980-33983, 33990-33992, and 33995-33997.

In simple words: The surgeon inserts a mechanical pump (VAD) inside the chest to help one side of the heart pump blood to the rest of the body. This is done for people with weak hearts or heart failure.

This code describes a procedure where a ventricular assist device (VAD) is implanted within the body (intracorporeal) to support a single ventricle of the heart. This procedure is typically performed for patients with weakened hearts or heart failure.

Example 1: A patient with severe heart failure who is not a candidate for a heart transplant undergoes VAD implantation as destination therapy., A patient with a severely weakened heart after a heart attack requires VAD implantation as a bridge to transplant while waiting for a donor heart., A patient undergoing open-heart surgery experiences complications and requires temporary support from an intracorporeal VAD.

Documentation should include the patient's medical history, heart failure symptoms, imaging studies, pre-operative evaluations, operative report detailing the procedure, and post-operative care plan.
