Ask Dr. Z

Should we use code 93618 for this procedure? "Patient has NICM and has a biventricular ICD for primary prevention. Although adequately biventricular paced, his QRS duration remains long and his intrinsic QRS seems shorter. Patient was brought to the lab in the post-absorptive state. IV antibiotics were administered prior to the procedure. After the left pectoral site was prepped and draped in the usual sterile fashion. The skin was infiltrated with 1% lidocaine and 1% bupivacaine for local anesthesia. Right axillary vein access was obtained using ultrasound guidance and seldinger technique. However, the wire could not be passed beyond the superior vena cava in spite of using multiple wires and multiple attempts. Then left axillary vein was accessed using ultrasound guidance. Although we tried using Biotronik and then Medtronik systems we could not identify the His location. Then right femoral groin access was obtained and then His mapping was attempted using RV and HIS catheters. But in spite of repeated attempts His could not be consistently mapped. Hence the procedure was aborted."
