On Demand: EP Series Part 3: The Basics of EP Studies and Ablations-Webinar Recording

Video Transcription

Video Summary

This webcast was part three of an EP coding series, led by Michelle and Tammy, focused on electrophysiology studies, arrhythmias, and ablation coding. The presenters reviewed heart conduction anatomy, common rhythms such as atrial flutter, atrial fibrillation, and ventricular tachycardia, and explained how providers document EP findings.<br /><br />Michelle covered diagnostic EP studies, including comprehensive and component codes, catheter pacing and recording, left atrial and left ventricular add-on services, 3D mapping, medication testing, intracardiac echo (ICE), and drug challenge testing. She also emphasized the importance of precise provider documentation and specificity in diagnosis coding.<br /><br />Tammy then explained ablation procedures, including AV node ablation, SVT ablation, VT ablation, and atrial fibrillation pulmonary vein isolation (PVI). She reviewed key add-on codes like 93655 and 93657, noted when mapping codes are or are not reportable, and highlighted coding nuances for posterior wall ablation, box lesions, coronary sinus work, and repeat PVI cases. She also discussed newer technologies such as pulse field ablation (PFA) and vein of Marshall ablation.<br /><br />Several case examples illustrated how to assign codes based on the documented procedures and arrhythmias treated. The session concluded with a Q&A addressing common issues such as discontinued procedures, cardioversion edits, ICD-10 rhythm coding, mapping documentation, and when additional posterior wall or coronary work can be separately reported.
