    CPT 93271: Ambulatory External Event ECG Monitoring, Transmission and Analysis

    Medicare pays $144 on average nationally for this procedure.

    CPT code 93271 describes a combined technical and professional service for ambulatory external event electrocardiographic monitoring in which the provider places ECG leads and an event recorder on the patient to record and transmit cardiac rhythm data for up to 30 days while the patient experiences symptoms; the service type is ambulatory symptom-triggered event monitoring with remote transmission and analysis, and the typical site of service is outpatient clinic or ambulatory diagnostic center where the device is applied and transmission is reviewed and interpreted by the provider.

    Clinical & Coding Specifications

    Clinical Context

    A 62-year-old patient presents to a cardiology clinic with intermittent palpitations and exertional lightheadedness. The provider determines ambulatory rhythm monitoring is indicated to correlate symptoms with cardiac rhythm. In the clinic, the clinician places an external event recorder with ECG leads on the patient’s chest and programs the device for patient-activated transmissions and auto-triggering for up to 30 days. The patient is instructed to transmit tracings at the onset of symptoms (eg, chest pain, palpitations, syncope) and to perform scheduled transmissions if required. During the monitoring period, transmitted ECG data are received via a secure network, reviewed by the interpreting clinician or qualified clinical staff, and analyzed to identify arrhythmia, ischemic changes, or conduction abnormalities. The clinician documents review of transmitted tracings, provides interpretation, and issues patient-specific advice on actions to take, which may include urgent evaluation, medication adjustment, or routine follow-up. Billing for the combined technical and professional components of the event recording and analysis is reported with 93271.
