What 93243 covers
This code covers the technical processing of ambulatory ECG data collected over more than 48 hours but less than seven days. After the monitoring device is returned or its data are transmitted, technical staff or a monitoring service scan and analyze the recorded rhythm and prepare a report. Extended monitoring can help evaluate intermittent palpitations, fainting, or suspected arrhythmias that may not appear during a brief office ECG. The service is commonly performed through an outpatient cardiology practice or an ECG monitoring vendor.
Report 93243 for the scanning, analysis, and report portion; it does not include the physician’s review and interpretation, which is separately represented by 93244. The complete service may instead be reported with 93241, while 93242 represents recording only. Documentation should support the monitoring duration and the technical analysis and report provided. CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component, including this code, when the reduction is triggered by multiple procedures.
