Ask Dr. Z

Our physician did a PVI ablation for persistent atrial fibrillation. He then documents non-PVI foci ablations of the LA roof line and the LA anterior wall. Would this be considered one unit of 93657? Or two?

Here is an excerpt from the report:

"The four PVs were sequentially ablated with loss of PV potentials in all four veins and exit block. RF ablation line was created across the LA roof from RSPV to LSPV. RF ablation line was then connected from this RF line to the anterior MV annulus. At the conclusion of the ablation lesions in the left atrium, the catheter/sheath was removed as a unit from the left atrium."
