    CPT 93270: Ambulatory Event Recorder — Technical Connection/Recording

    Medicare pays $9 on average nationally for this procedure.

    CPT code 93270 describes the technical component for connection, recording, and disconnection of an ambulatory event recorder used to monitor and record a patient’s heart rhythm during symptomatic episodes; the device is configured with electrocardiogram leads on the chest and can transmit ECG tracings for up to 30 days while the patient activates transmissions before and during symptoms, with subsequent clinician analysis and advice. Service type: Technical component of ambulatory event monitoring (device connection/recording/disconnection). Typical site of service: Outpatient clinic, cardiac diagnostics lab, or ambulatory monitoring service with remote transmission capability.

    Clinical & Coding Specifications

    Clinical Context

    A 58-year-old patient presents to a cardiology clinic reporting intermittent palpitations and occasional chest discomfort lasting seconds to minutes over several weeks. The clinician determines that symptoms are intermittent and may not be captured on a standard 12-lead ECG or a 24–48 hour Holter monitor. The clinician places an ambulatory event recorder with ECG leads on the patient’s chest and connects the device, which the patient will wear and use to transmit symptomatic ECG tracings for up to 30 days. The patient is instructed to activate the recorder and transmit strips during symptoms and to perform any scheduled transmissions. The clinic’s cardiac technologist or technician performs the technical component: lead placement, device setup, patient education, technical monitoring, and device disconnection/return. The cardiologist or other credentialed provider subsequently reviews transmitted tracings, interprets rhythm events, documents findings, and communicates recommended next steps to the patient. Typical sites of service include outpatient cardiology clinics, ambulatory procedure centers, and occasionally emergency department observation areas when extended rhythm monitoring is indicated. This service represents the technical component (connection, recording, disconnection) of ambulatory event monitoring for symptomatic correlation over an extended recording period.
