Ask Dr. Z

CPT Assistant (November 2020) states that a patient does NOT have to be in Afib if patient has persistent or paroxysmal Afib in order to code 93657 (additional Afib ablation), although the code still reads Afib should be remaining. So if PVI is complete and a linear carina line is required, can we code for the 93657 when the patient is not still in Afib after PVI is complete? Also, if the carina line is performed for "right PVs were difficult and required carina line for isolation", could that be reported with 93657 or not since it sounds like they are still isolating the PVs?
