Cardiac Event Detection Monitoring - CPT 93268, 93270,93271, 93272 with DX LIST

Cardiac Event Detection involves the use of a long-term monitor by patients to document a suspected or paroxysmal dysrhythmia. Following the recording of events, the patient transmits data via telephone to a physician’s office or a specified station that is equipped and staffed to assess electrocardiographic data and to initiate appropriate management action. The device must be patient-activated.

The CPT/HCPCS codes that follow have two key distinguishing features:
  • The distinction between a monitor with and without presymptom loop.
  • The availability of full 24-hour attended coverage for certain specified services.
Indications
The covered indications are:
  • To detect, characterize and document symptomatic transient arrhythmias.
  • To aid in regulating anti-arrhythmic drug dosage.
  • To aid in the search for the cause of unexplained syncope, dizziness or giddiness.
Based on the above covered indications, the following clinical scenarios would be considered consistent with the above indications:
  • To detect the presence of symptomatic transient arrhythmias (the frequency of the symptom would make a 24-hour ambulatory electrocardiogram (Holter) not useful in documenting the rhythm).
  • To monitor for the purpose of regulating anti-arrhythmic drug dosages.
  • To monitor patients who have had surgical or ablative procedures for arrhythmias.
Limitations
A Cardiac Event Detection service is medically unnecessary if it offers little or no potential for new clinical data beyond that which has been obtained from a previous test or if other tests are better suited to obtain the clinical data relevant to the patient’s condition. The Cardiac Event Detection should be coordinated with results from standard EKGs, Holter monitor tests and stress tests.

For 24-hour attended monitoring services, the receiving station must be staffed on a 24-hour basis and should be able to direct the patient for the management of all emergencies. An answering service/answering machine would not fulfill this requirement.

In addition, systems utilizing computers to dial the physician’s office so the physician receives transmission by way of a relay is not a covered service since there is no attendance.
Cardiac event monitoring must be 24 hours a day, seven days a week attended for reimbursement.

A test may be ordered only by a physician or qualified non-physician practitioner treating the beneficiary.

Although the service is a 30-day service, it is recognized that the event recorder may be discontinued once the symptom-producing arrhythmia has been documented and diagnosed or following multiple transmissions during symptoms, without arrhythmia. It is unlikely that the arrhythmias would always be diagnosed on the first day of recording or that the service would always last only one day. The average duration of monitoring is anticipated to last 10–14 days or more.

The Cardiac Event Detection service is justified by the pre-test incidence of symptoms related to arrhythmias and is considered not medically necessary for those patients who are not having significant recurrent arrhythmias that are anticipated to require treatment.

Testing for more than 30 consecutive days is rarely medically necessary and the need for the continued monitoring must be justified by the treating physician. Failure to document an arrhythmia during a 30-day test period is not sufficient justification to reimburse a second or subsequent test. It is unlikely to be medically necessary to repeat a second test within a year in the absence of new or recurrent undiagnosed symptoms.

Event recorders must be patient-activated and may not use time-sampling technology. Accordingly, this test will be considered medically unnecessary for any patient who is unresponsive, comatose, severely confused or otherwise unable to recognize symptoms or activate the recorder.

Event recorders are not covered for outpatient monitoring of recently discharged postinfarct patients.

Because the Cardiac Event Detection service requires the diagnosis and evaluation of intermittent arrhythmias and patients must be continuously attached to presymptom loop recorders or be able to be attached at the start of symptoms to postsymptom loop recorders, each patient is required to have a recorder for his/her own exclusive use throughout the duration of the monitoring period. Recorders may not be “shared” amongst two or more patients, regardless of the environment or site of the service. It will be deemed medically unnecessary to perform cardiac event recording services when patients do not have exclusive use of a recorder for the entire service period (30 days).

Cardiac Event Detection is a 30-day packaged service. Tests may not be billed within 30 days of each other, even if the earlier of the tests was discontinued when arrhythmias were documented and the patient is now reconnected for follow-up of therapy or intervention.

Compliance with the provisions in this policy is subject to monitoring by postpayment data analysis and subsequent medical review.
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.
As published in CMS IOM 100-08, Section 13.5.1, to be covered under Medicare, a service shall be reasonable and necessary. When appropriate, contractors shall describe the circumstances under which the proposed LCD for the service is considered reasonable and necessary under Section 1862(a)(1)(A). 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.
12X, 13X, 18X, 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.
Note: TrailBlazer has identified the Bill Type and Revenue Codes applicable for use with the CPT/HCPCS codes included in this LCD. Providers are reminded that not all CPT/HCPCS codes listed can be billed with all Bill Type and/or Revenue Codes listed. CPT/HCPCS codes are required to be billed with specific Bill Type and Revenue Codes. Providers are encouraged to refer to the CMS Internet-Only Manual (IOM) Pub. 100-04, Claims Processing Manual, for further guidance.

Diagnoses That Support Medical Necessity
The following “E” codes may be used as a secondary diagnosis when other covered ICD-9-CM diagnosis codes are used as the primary diagnosis.
E942.0
Cardiac rhythm regulators causing adverse effects in therapeutic use
E942.1
Cardiotonic glycosides and drugs of similar action causing adverse effects in therapeutic use
E942.9
Other and unspecified agents primarily affecting the cardiovascular system causing adverse effects in therapeutic use
Note: Use of these “E” codes will provide further clarification of the need for the procedure, but does not affect coverage.
ICD-9-CM Codes That DO NOT Support Medical Necessity
N/A
Diagnoses That DO NOT Support Medical Necessity
All diagnoses not listed in the “ICD-9-CM Codes That Support Medical Necessity” section of this LCD.
Documentation Requirements
Documentation supporting medical necessity should be legible, maintained in the patient’s medical record and made available to Medicare upon request.
When requesting a written redetermination (formerly appeal), providers must include all relevant documentation with the request.

Records must include ECG rhythm strips with interpretation for each transmission, the date and time of each transmission, when the symptoms occurred and what the symptoms were must be documented for each transmission. The medical record should also include when the reviewing physician and the ordering physician were notified of the transmission and its results.

The Cardiac Event Detection provider’s records must include the referring physician’s request for the test and the indications for the test. This information should be incorporated into a formal report (interpretation) of the test.

Documentation of the necessity should include the referring physician’s diagnostic impression and an indication of relevant signs and symptoms.

It is not enough to link the procedure code to a correct, payable ICD-9-CM diagnosis code. The diagnosis or clinical suspicion must be present and documented in the clinical record for the procedure to be paid.

Utilization Guidelines
In a symptomatic patient, it is expected that it would not be necessary to perform a Cardiac Event Detection service (one 30-day service) more frequently than once every six months.
Notice: This LCD imposes utilization guideline limitations. Despite Medicare’s allowing up to these maximums, each patient’s condition and response to treatment must medically warrant the number of services reported for payment. Medicare requires the medical necessity for each service reported to be clearly demonstrated in the patient’s medical record. Medicare expects that patients will not routinely require the maximum allowable number of services.
