Decode This CRT Scenario With Ease

Question: The doctor implanted a cardiac resynchronization therapy (CRT) device, and he could not position the left ventricular (LV) lead. He opted for either a bundle of HIS lead or a left bundle branch (LBB) lead to act as the coronary sinus (CS) lead. He bills this as a CRT. I’m looking in the documentation for the CS lead, and there isn’t one. How should I bill this procedure?

Answer: Cardiac resynchronization therapy (CRT), also known as biventricular pacing therapy is used for patients who have left and right ventricles that do not pace in unison due to arrhythmia. In addition to the right ventricular lead, a pacing electrode commonly called the coronary sinus lead or left ventricular lead is placed. There are two types of CRT therapy, CRT-P for a biventricular pacemaker and CRT-D for a biventricular defibrillator. A bundle of HIS lead or a LBB lead is not considered a traditional biventricular lead placed vis coronary sinus and cannot be billed with +33225 (Insertion of pacing electrode, cardiac venous system, for left ventricular pacing, at time of insertion of implantable defibrillator or pacemaker pulse generator…). Some insurances may accept the unlisted code 33999.
