Temporary Nontherapeutic Ambulatory Cardiac Monitoring Devices

Temporary non-implanted ambulatory cardiac monitoring devices (Holter, event recorders, patch, ELR, MCT/MCOT) are covered when used to diagnose or manage intermittent arrhythmia-related symptoms (infrequent episodes >24 hours apart), to guide antiarrhythmic medication management, after ablation/surgery, or to evaluate cryptogenic/non-lacunar stroke/TIA for atrial fibrillation and in select cardiomyopathies for ventricular arrhythmia assessment.
