Wearable electrocardiographic rhythm derived monitoring for 24 hours by continuous computerized monitoring and non-continuous recording, and real-time data analysis utilizing a device capable of producing intermittent full-sized waveform tracings, possibly patient activated; includes monitoring and real-time data analysis with report, physician review and interpretation

Wearable electrocardiographic rhythm-derived monitoring, as described by CPT® Code 93235, involves the collection of electrocardiographic (ECG) data over a continuous 24-hour period. This procedure is performed using a specialized device known as a Holter monitor, which the patient wears during their normal daily activities. The Holter monitor consists of electrodes or leads that are affixed to the patient's chest, allowing for the continuous recording of the heart's electrical activity. The device is designed to provide uninterrupted computerized monitoring of ECG signals throughout the day, capturing various heart rhythms and rates. During this monitoring period, the device analyzes the ECG data in real-time, identifying any abnormal rhythms that may occur. The patient may also have the option to activate the device manually if they experience symptoms, prompting the device to record and analyze the data at that moment. The Holter monitor generates intermittent full-sized waveform tracings or printouts of selected ECG rhythm strips based on the analysis of the recorded data. The information collected includes critical metrics such as heart rhythm and rate, ST segment analysis, heart rate variability, and T-wave alternans. After the monitoring period, a physician reviews and interprets the data to assess for potential heart arrhythmias. The comprehensive nature of this procedure, which encompasses monitoring, real-time data analysis, and physician interpretation, is encapsulated in the reporting of CPT® Code 93235. For cases where only monitoring and data analysis are performed without physician interpretation, CPT® Code 93236 is applicable, while CPT® Code 93237 is designated for instances where only the physician's review and interpretation of the data are reported.
