We have 93657 and 93655. Questioning if the dissociated PV potentials ablated that is noted here would meet criteria for code 93657.

"DX persistent A fib/typical A Flutter. CTI ablation 5:30-6:00 position of the TV annulus. Line interrogated and block confirmed. Geometry created of LV and pulmonary veins. Low voltage areas over posterior wall. Four vein pulmonary isolation done; first pass achieved right side isolation. Linear carina ablation. Gaps ablated in the region of the left posterior carinal region. After isolation, block confirmed. Dissociated PV potentials noted in the bilateral pulmonary veins. Lesions of posterior wall were contained to 5 seconds or less. Impedance drop of 10 ohms, current delivery and FTI index was closely monitored."
