CPT® Code 93226

External electrocardiographic recording up to 48 hours by continuous rhythm recording and storage; scanning analysis with report

External electrocardiographic recording, identified by CPT® Code 93226, involves the continuous monitoring of a patient's heart rhythm for a duration of up to 48 hours. This procedure utilizes an external electrocardiogram (ECG) device, commonly referred to as a Holter monitor, which is worn by the patient during their normal daily activities. The process begins with the placement of electrodes or leads on the patient's chest, allowing for the capture of the heart's electrical activity. The Holter monitor records this activity continuously, generating original ECG waveforms that are stored on a magnetic tape or a digital medium for subsequent analysis. The data collected during this monitoring period includes critical information such as heart rhythm, heart rate, ST segment analysis, heart rate variability, and T-wave alternans. After the monitoring period concludes, the patient returns the device to the healthcare provider, where the stored data undergoes a detailed scanning analysis. This analysis involves visual superimposition scanning, which provides a comprehensive overview of the entire recording, enabling the identification of various ECG waveforms and selective rhythm strip samples. A report is generated following this analysis, which is then reviewed and interpreted by a physician or qualified healthcare professional to assess for any heart arrhythmias. It is important to note that this code specifically pertains to the analysis of the scanning with report, distinguishing it from other related codes that cover different aspects of the procedure.
