Twenty-four hour electrocardiographic (ECG or EKG) monitoring is also referred to as long-term ECG recording, Holter monitoring or recording and dynamic electrocardiography. It is a diagnostic procedure that provides a continuous record of the ECG waveform during daily activities. This procedure is used to identify the existence of, and determine the frequency of, clinically significant rhythm disturbances and waveform abnormalities that are missed on a standard ECG. These codes are to be reported and billed only one time in any given twenty-four-hour period.
CPT Codes ranges: 93224 - 93227 and 93230 - 93233
