Date: Oct 10, 2022

Question:

EP provider completes PVI ablation and confirms entrance and exit block from the pulmonary veins (93656). He documented patient had known typical atrial flutter and does a CTI ablation (93655).

"And then complete ablation of the right atrial subeustachian isthmus and the left atrial Marshall bundle were identified as possible potentiating triggers for atrial fibrillation and were therefore ablated for atrial fibrillation remaining after pulmonary vein isolation."
