Temporary Nontherapeutic Ambulatory Cardiac Monitoring Devices

Temporary non-implanted ambulatory cardiac monitoring devices (Holter, event/patch/loop recorders, MCT/MCOT) are covered when used for diagnostic evaluation of infrequent symptomatic arrhythmias (>24 hours between episodes), for arrhythmia medication management, post-procedure monitoring, or to detect atrial fibrillation after cryptogenic/non-lacunar stroke or TIA, and for arrhythmia surveillance in specified cardiomyopathies and channelopathies. Devices must be FDA-cleared, patient- or event-activated with intermittent or continuous monitoring, monitored by a 24-hour staffed monitoring station with emergency notification capability, and are generally limited to a 30-day packaged service; testing beyond 30 days or repeated testing within 30 days (or usually within a year) requires documented justification and is rarely covered.
