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

Webinar Slides

Pdf Summary

This MedAxiom webcast provides a practical overview of electrophysiology (EP) studies and ablations, focusing on anatomy, arrhythmia interpretation, and coding rules. It explains the heart’s electrical system and common ECG patterns, then reviews major arrhythmias such as atrial flutter, atrial fibrillation, ventricular tachycardia, and torsades de pointes, including their clinical and coding distinctions.<br /><br />The presentation outlines why EP studies are performed: to identify the origin and cause of abnormal rhythms and guide treatment. It describes what may appear in a comprehensive EP report, including catheter placement, pacing and recording from multiple heart chambers, arrhythmia induction, and physician interpretation. It distinguishes comprehensive EP study codes from component codes used when only portions of the study are performed.<br /><br />The session also covers mapping, including standard 2D mapping and 3D electroanatomic mapping, and notes that 3D mapping supersedes standard mapping when both are used. Additional diagnostic codes discussed include programmed stimulation after IV drug infusion (93623) and intracardiac echo (93662). The webcast highlights documentation clues coders should look for in reports.<br /><br />A major section addresses ablation coding: AV node ablation (93650), SVT ablation (93653), VT ablation (93654), and pulmonary vein isolation for atrial fibrillation (93656). It explains bundled services and separately reportable add-on codes such as 93655 (separate arrhythmia mechanism), 93657 (additional AF ablation after PVI), 93623, 93662, 93462, and 93621/93622 when appropriate. It also reviews NCCI edits, ultrasound restrictions, cardioversion rules, and device evaluation limitations.<br /><br />Several case studies illustrate how documentation supports code selection for EP studies, drug challenges, AV node ablation, SVT ablation, VT ablation, and complex AF ablation using pulsed-field ablation.
