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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
