2025 CPT code 93224
(Active) Effective Date: N/A Revision Date: N/A Cardiovascular Monitoring Services Feed
External electrocardiographic recording up to 48 hours by continuous rhythm recording and storage; includes recording, scanning analysis with report, physician review and interpretation.
Modifier 52 can be applied if the service is significantly reduced.
Medical necessity for this code must be supported by documentation that justifies the need for continuous ECG monitoring over a 48-hour period to evaluate symptoms or conditions potentially related to cardiac arrhythmias.
The physician is responsible for the entire process, including patient instruction, application and removal of the recorder, analysis, interpretation, and reporting.
In simple words: A small, wearable device records your heart's electrical activity continuously for up to two days. This helps doctors find irregular heartbeats. The process includes attaching the device, wearing it, and then having a doctor review the recordings.
This code encompasses the complete process of Holter monitoring for up to 48 hours, including the application of the ECG recorder, continuous recording and storage of ECG data, scanning analysis of the recording, generation of a report, and the physician's review and interpretation of the findings. The procedure involves instructing the patient, placing electrodes, connecting the recorder, and subsequent removal and data download. It is used to detect abnormal heart rates and rhythms. The physician analyzes compiles, and interprets the data, correlating it with patient-logged diary events.
Example 1: A patient experiencing palpitations and dizziness undergoes a 48-hour Holter monitoring to assess for any underlying cardiac arrhythmias., A patient with a history of syncope undergoes Holter monitoring to evaluate for bradycardia or other rhythm disturbances that may be contributing to the episodes., Following a myocardial infarction, a patient undergoes Holter monitoring to detect any silent ischemia or arrhythmias that may not be apparent during a resting ECG.
Documentation should include the reason for the monitoring, the duration of the recording, a summary of the findings including any significant arrhythmias, and the physician’s interpretation and recommendations. Patient-logged diary events correlating symptoms with time are also crucial for accurate assessment.
