Left atrial roof ablation after pulmonary vein isolation

Date: Sep 18, 2020

Question:

I have a physician who reports that "additional radiofrequency energy was delivered across the left atrial roof and floor to achieve posterior wall electrical isolation". He does not state that atrial fibrillation continued, so we can't report 93657 for this. I was wondering if we can report 93655. The MD does not state the "discrete mechanism of arrhythmia". Can we assume that there was another discrete mechanism if he performed those additional ablations?
