Ask Dr. Z

After a PVI ablation, patient remained in atrial fibrillation so decision was made to perform more extensive ablation including a roof and floor line with RF. A tacti-cath catheter was inserted through the flexcath advance. Atrial fibrillation terminated by CV. Remap of left atrium performed. Roof line cryoablated with 4 120 s lesions with achieve anchored in the LSPV, and 2 120 sec additional lesions with the achieve anchored in the RSPV. Floor line cryoablated with 2 120 s lesions with achieve anchored in the LSPV, and 3 120 sec additional lesions with the achieve anchored in the RSPV. Does the floor and roof line ablation post PVI ablation for continued a-fib support coding 93657 x 2?
