Holter monitoring is a form of long-term ECG recording. It is a diagnostic procedure that provides a continuous record of electrical activity of a patient’s heart while the individual is engaged in ordinary activities, including sleep. Holter monitoring is used to detect abnormalities related to rhythm, rate, conduction and ischemia, which are not observed using a standard ECG.
Basic components of Holter monitoring systems are a sensing element, an appropriate recording of ECG information or significant variations in rate or arrhythmia, and a component for graphically recording ECG data or for visual or computer assisted analyses of recorded taped information.
  • Detecting transient episodes of cardiac dysrhythmia, permitting correlation of these episodes with cardiovascular symptoms.
  • Evaluation of the patient with symptoms suggestive of a cardiac dysrhythmia when another cause cannot be established.
  • Evaluation of arrhythmias in patients with documented coronary artery disease, including the assessment of the immediate postmyocardial infarction patient.
  • Monitoring the effectiveness of antiarrhythmic therapy.
  • Syncope and presyncope are covered indications for Holter monitoring and real-time monitoring.

  • Holter monitoring and real-time monitoring are not covered for the detection of silent ischemia in patients without symptoms suggestive of ischemia. Routine screening in the absence of signs, symptoms, and complaints is not covered under Title XVIII of the Social Security Act, Section 1862(a)(7).
  • Holter monitoring and real-time monitoring are not covered for patients with incidental findings of conduction system defects absent a qualifying indication listed above.
  • Holter monitoring and real-time monitoring for vague symptoms such as dizziness are not covered in the absence of symptoms or signs that would suggest cardiac origin of the symptoms.
Notice: This LCD imposes diagnosis limitations that support diagnosis to procedure code automated denials. However, services performed for any given diagnosis must meet all of the indications and limitations stated in this policy, the general requirements for medical necessity as stated in CMS payment policy manuals, any and all existing CMS national coverage determinations, and all Medicare payment rules.
Contractors shall consider a service to be reasonable and necessary if the contractor determines that the service is:

  • Safe and effective.
  • Not experimental or investigational (exception: routine costs of qualifying clinical trial services with dates of service on or after September 19, 2000, which meet the requirements of the clinical trials NCD are considered reasonable and necessary).
  • Appropriate, including the duration and frequency that is considered appropriate for the service, in terms of whether it is:
    • Furnished in accordance with accepted standards of medical practice for the diagnosis or treatment of the patient’s condition or to improve the function of a malformed body member.
    • Furnished in a setting appropriate to the patient’s medical needs and condition.
    • Ordered and furnished by qualified personnel.
    • One that meets, but does not exceed, the patient’s medical need.
    • At least as beneficial as an existing and available medically appropriate alternative.

Bill Type Codes
Contractors may specify Bill Types to help providers identify those Bill Types typically used to report this service. Absence of a Bill Type does not guarantee that the policy does not apply to that Bill Type. Complete absence of all Bill Types indicates that coverage is not influenced by Bill Type and the policy should be assumed to apply equally to all claims.
11X, 13X, 21X, 22X, 23X, 71X, 73X, 75X, 77X, 85X
Bill Type Note: Code 73X end-dated for Medicare use March 31, 2010; code 77X effective for dates of service on or after April 1, 2010.
Revenue Codes
Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory; unless specified in the policy services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the policy should be assumed to apply equally to all Revenue Codes.

Providers are reminded to refer to the long descriptors of the CPT codes in their CPT book. The American Medical Association (AMA) and the Centers for Medicare & Medicaid Services (CMS) require the use of shortCPT descriptors in policies published on the Web.

Electrocardiograph Holter Monitoring Policy Status: Active  Effective: 12/01/2012

Please note: All policies are subject to the terms, conditions and limitations of the member’s plan or program


Holter monitors are portable devices that capture 48 hours or more of continuous external electrocardiographic (ECG) recording and storage, and are used to detect atypical heart rhythms.

The services comprising Holter monitoring can be reported by using one Current Procedural Terminology (procedure ®) code for the global service, or they can be reported by using a combination of the professional and technical component codes for:

• recording of the ECG (which includes the hook-up and disconnection)

• scanning analysis with report

• physician review and interpretation


1. Non-hospital setting:

ECG Holter Monitoring is eligible for reimbursement when billed as a global service which encompasses both the technical and the professional components, or when a combination of the technical and the professional component services are reported. When a participating provider utilizes an outside non-par vendor for some or all of the technical components of this service, the participating provider is responsible for billing the global service (technical and professional components) and reimbursing the subcontracted vendor.

This will avoid increased member financial liability due to your use of an out-of-network provider as well as member abrasion.

 2. Hospital Setting:

Hospital-Based Physicians and private physicians are only eligible to be reimbursed for the professional component. The hospital may bill for the technical components.

ICD-9-CM Codes That Support Medical Necessity
The CPT/HCPCS codes included in this LCD will be subjected to “procedure to diagnosis” editing. The following lists include only those diagnoses for which the identified CPT/HCPCS procedures are covered. If a covered diagnosis is not on the claim, the edit will automatically deny the service as not medically necessary.

Cardiac arrhythmias are abnormal heart rhythms. Although some patients with arrhythmias may experience palpitations, weakness, dizziness or fainting, other patients may have no symptoms at all. Effective treatment requires an accurate diagnosis. This can be difficult since arrhythmias can occur infrequently and unpredictably and may be asymptomatic (ECRI, 2014). The type and duration of ambulatory electrocardiography (ECG) monitoring is dictated by the frequency of symptoms.

• Holter monitors are portable devices that record heart rhythms continuously for up to 48 hours. These devices are used to record events that occur at least once a day.

• Non-implantable cardiac event monitors are portable devices that record heart rhythms intermittently for up to 30 days.

These devices capture ECG data before, during and after the time of activation.

• Standard loop recorders have just a few minutes of memory. Newer, more sophisticated devices have extended memory features that can store up to several hours of ECG data.

Recording can be patient-activated when symptoms occur or automatically triggered based on a computer algorithm designed to detect arrhythmias. These devices are used to record infrequent or irregular events.
Documentation Requirements
  • Documentation supporting medical necessity should be legible, maintained in the patient’s medical record and made available to Medicare upon request.
  • A formal report for every study must be generated that indicates the reason(s) for the test and includes the electrocardiographic interpretation.
  • An appropriate medical evaluation of the patient prior to the test must be documented in the patient’s record by the referring physician. This should include a history and physical examination that is of sufficient scope and detail to support medical necessity for the test.
  • To verify the necessity and reasonableness of the test, the performing physician should, at minimum, document the diagnostic impression of the referring physician and indicate the patient’s relevant signs, symptoms or pertinent history in his records. The simple statement of certain non-specific test indications (such as chest pain or palpitations, etc.) is unacceptable medical necessity documentation.
