Heritage Health (Medicaid):

Effective May 1, 2026, there will be an update to the Holter Monitors clinical policy.  For additional information,  please review Holter Monitors under the clinical policies.

CP.MP.113 Holter Monitors

Policy Description: This policy provides medical necessity guidelines for Holter monitoring up to 48 hours. For Holter monitoring beyond 48 hours, see clinical decision support criteria. 

Ambulatory electrocardiogram (ECG) monitoring provides a view of cardiac activity over an extended period of time and can be performed using various techniques. The method selected to conduct ambulatory ECG monitoring depends on the desired outcome and the frequency and duration of symptoms. Continuous Holter monitoring for 24 to 48 hours is the most practical initial approach for those with daily or near daily unexplained symptoms, as well as for assessing the efficacy of medication and other treatments for cardiac arrhythmias. 

If you have questions, please contact Provider Relations.
