    Clinical & Coding Specifications

    Clinical Context

    A 68-year-old patient with intermittent unexplained palpitations and syncope is followed after implantation of an insertable cardiac monitor (implantable loop recorder). The device continuously records cardiac rhythm and transmits data remotely through a patient transmitter or smartphone application. Within a 30-day period, the remote monitoring service receives transmissions that include arrhythmia alerts, device diagnostic data, and patient-initiated event recordings. A trained cardiac device technician performs receipt and preliminary technical review of the transmitted data, filters artifacts, documents relevant telemetry, and prepares a technical report for the supervising cardiologist or electrophysiologist. The supervising physician reviews the technician findings, performs clinical interpretation as indicated, and the clinic issues the monitoring results to the patient and referring provider. Typical workflow steps: device transmission receipt, technician review and triage, escalation of clinically significant events to the physician, physician interpretation and documentation, and distribution of results to the patient and referring clinician. Typical site of service is an outpatient cardiac device clinic, electrophysiology clinic, or remote monitoring center associated with a hospital or ambulatory practice. Service type is remote device interrogation and technical review of implantable cardiovascular physiologic monitor systems (implantable loop recorders) for up to 30 days, including receipt of transmissions, technician review, technical support, and distribution of results.
