CPT code 93242: Ambulatory ECG recording, more than 48 hours, under 7 days2026 Medicare rate & RVUs in California

Medicare pays $12.63–$16.55 for 93242 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93242 covers

Code 93242 covers the technical recording portion of ambulatory electrocardiographic monitoring that runs longer than 48 hours but less than seven days. A patient wears an external monitor during usual activities so the recording can capture intermittent rhythm abnormalities that a brief office ECG may miss, such as episodic palpitations or unexplained fainting. Cardiology practices and other qualified monitoring providers commonly furnish the recording service in outpatient care.

Report 93242 for recording only, selecting it by the monitoring duration rather than symptoms or number of tracings. Documentation should support the device used and the recording period. Scanning analysis with a report and physician review and interpretation are separate services represented by 93243 and 93244, not work included in 93242. CMS classifies 93242 as technical-component-only, and a cardiovascular diagnostic multiple-procedure reduction applies to its technical component.
