Ask Dr. Z

Presenting rhythm was atypical atrial flutter, patient does have a hx of A-fib, MD wants to bill 93656 & 93657. He documented that the patient had atypical AF originating from LA. So he performed ablation for a-fib (93656) in the same setting as well as posterior wall isolation for add'l lines (93657). He did not do cavotricuspid isthmus ablation which is performed for typical atrial flutter originating in the right atrium.

"PFA Catheter catheter was delivered to the LA, and the PVs were sequentially isolated to an endpoint of vein potential eradication and exit block. Posterior wall isolation was performed. Atypical flutter terminated upon ablation at the roof of the LUPV ostium.

Final dx: Symptomatic Recurrent Drug Refractory Persistent Atypical Atrial Flutter s/p Pulsed Field Ablation PVI."

No mention of A-fib just PVI. Is it still correct to bill PVI 93656 & 93657?
