Ask Dr. Z

Should the following be reported as 33216 and 93642? Or 33216 and 93641? "Usual prep and drape was done in sterile fashion. Anesthesia used was 1% xylocaine. Following satisfactory anesthesia, the generator of the ICD was explanted using sharp and blunt dissection. Following this, the lead was disconnected from the device. A new right ventricular lead was then placed using sheath placement with Seldinger technique in the subclavian vein on the left. This was advanced into the apex of the right ventricle, and satisfactory pacing and sensing thresholds were obtained. This was then attached to the existing generator and the excess lead and generator placed in the pocket. The pocket was flushed with antibiotic solution and was closed using running 3-0 Dexon suture for the subcutaneous tissue and subcuticular running suture of same for the skin. Following this, the patient was placed in ventricular fibrillation with a T shock, and the device successfully cardioverted the patient back to a sinus mechanism with 10 joules."
