PVI and Additional Lines

Please note this question was answered in 2014. The coding advice may or may not be outdated.


We are debating a case and need your expert advice. Our EP physicians are saying we should be able to bill code 93657 x 2 for both of the additional ablations, and they indicated the medical necessity in their dictation. Due to the allowed space, I have only sent you their conclusion. "Successful EP study with successful ablation of the mitral isthmus line, anterior line, and septal line. Successful ablation guided by 3D mapping. Left atrial recording successful. Uncomplicated transseptal puncture assisted by intracardiac echo. EP study after Isuprel infusion with induction of typical right atrial flutter. Successful ablation of cavotricuspid isthmus with bidirectional block demonstrated. Successful cardioversion out of atrial fibrillation at the start of the procedure to determine whether the previous lines were blocked." We billed codes 93656, 93613, 93622, 93623, 93655, and 93657 x 2. Is there any time that you can bill 93657 x 2? We don't see this very often and would appreciate your advice and direction.
