Vein of Marshall ablation for flutter

Date: Nov 2, 2023

Question:

We performed a PVI ablation for atrial fibrillation. Following the PVI, we ablated the floor line and roof line (box set). “During this, the patient went into atrial fibrillation." Next, we performed a vein of Marshall ablation on the “mitral isthmus flutter”, followed by a CTI. We think this is coded with 93656 (PVI), 93657 (box set), and 93655 x2 (VOM for atrial flutter and CTI). Do you agree with these codes?
