Summary & Overview
CPT 93243: ECG Recorder Scanning and Report After 48 Hours to 7 Days
CPT code 93243 covers the technician-performed scanning analysis and report of electrocardiographic data following ambulatory ECG recorder use for more than 48 hours up to 7 days. This code captures a common post-monitoring service in cardiac diagnostics that supports detection of arrhythmias and other rhythm disturbances outside the clinic setting. Nationally, accurate coding for extended ambulatory ECG analysis influences quality measurement, claims processing, and continuity of cardiac care.
Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing context for the service, the typical site of service, and which stakeholders are commonly involved in coverage and claims. The publication outlines how 93243 fits into ambulatory ECG workflows and identifies areas where payers commonly set coverage parameters.
This summary prepares readers for deeper sections covering benchmark payments, payer-specific coverage notes, coding guidance, and related service line considerations. Data not available in the input will be flagged in the detailed sections where applicable.
Billing Code Overview
CPT code 93243 describes the scanning analysis and reporting of electrocardiographic data after a patient has worn an ECG recorder for more than 48 hours up to 7 days to detect abnormal heart rates and rhythm. The service is performed by a processing center technician who conducts a scanning analysis and prepares a report of the electrocardiographic findings.
Service type: ECG monitor scanning and report after extended ambulatory monitoring
Typical site of service: Processing center or cardiac monitoring facility

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with episodic palpitations and intermittent lightheadedness is referred for ambulatory rhythm monitoring after initial evaluation in the outpatient cardiology clinic. The patient is fitted with a wearable continuous electrocardiographic recorder that will be worn for 5 days to detect paroxysmal atrial fibrillation and other arrhythmias. After completion of the wear period, the device is returned to a remote processing center where a trained technician performs scanning analysis and generates a summarized report of electrocardiographic findings for physician review. The cardiology clinic receives the technician report, the interpreting cardiologist reviews and correlates events with the clinical history, documents a final interpretation, and communicates significant findings to the patient and referring provider. Typical sites of service include outpatient cardiology clinics, ambulatory monitoring service centers, and remote processing facilities associated with the monitoring vendor.
