Summary & Overview
CPT 93248: Extended Ambulatory ECG Monitoring Interpretation
Headline: CPT code 93248 defines interpretation of extended ambulatory ECG recordings (7–15 days).
CPT code 93248 represents the professional review and interpretation of electrocardiographic data after a patient has worn an ECG recorder for more than seven days, up to 15 days. This service captures the clinician’s role in analyzing extended ambulatory monitoring to detect abnormal heart rates and rhythms, a critical element in diagnosing intermittent arrhythmias that shorter recordings may miss. Nationally, demand for extended monitoring has grown as wearable and patch-based technologies enable longer, patient-friendly surveillance.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context and typical sites of service, plus what to expect from coding and billing perspectives. The publication summarizes common modifiers and payer considerations, presents benchmarking examples where available, and outlines policy updates or coverage trends that affect reimbursement and utilization of extended ECG monitoring. Clinical implications for arrhythmia detection, workflow impacts for outpatient cardiology and remote monitoring programs, and documentation elements relevant to claims are described. Data not available in the input are noted where applicable.
Billing Code Overview
CPT code 93248 describes the review and interpretation of electrocardiographic data after a patient has worn an ECG recorder for more than seven days and up to 15 days to detect abnormal heart rates and rhythm. This service involves a clinician analyzing the extended ambulatory ECG recording, summarizing findings, and producing an interpretation report.
-
Service type: Extended ambulatory ECG monitoring interpretation and reporting
-
Typical site of service: Ambulatory or outpatient settings where long-term cardiac monitoring devices are applied and reviewed (for example, cardiology clinics, outpatient cardiac diagnostic centers, or remote monitoring programs)
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with intermittent palpitations and syncope wears an ambulatory electrocardiographic patch recorder continuously for 10 days prescribed to detect arrhythmia. The device is applied in the outpatient cardiology clinic and the patient returns the device to the clinic or mails it to the monitoring vendor at the end of the wear period. After data retrieval, a board-certified cardiologist or cardiac electrophysiologist performs an analysis, review, and formal interpretation of the >7 to 15 day continuous ECG tracing, documents findings in the patient record, and communicates actionable results to the referring clinician. Typical workflow elements include device set-up and patient education at device placement, secure data transmission from the device vendor, physician review of the entire tracings and event correlations, creation of an interpretation report, and billing for the review and interpretation service.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When billing only the physician interpretation separate from technical device services |
59 | Distinct procedural service | When the interpretation is distinct from another separately reportable evaluation or procedure |
