Summary & Overview
CPT 93745: Wearable Cardioverter Defibrillator Setup and Programming
CPT code 93745 describes the initial setup and programming of a wearable cardioverter defibrillator (WCD). The service combines technical device configuration, baseline data collection transmitted to a central monitoring system, and patient education on device use. This code is nationally relevant because WCDs play a role in short-term protection from sudden cardiac arrest for high-risk patients, and accurate billing for initial setup affects device access and care coordination.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for 93745, expected sites of service (outpatient device or cardiology clinics and hospital outpatient departments), and the components typically included in the billed service.
The publication summarizes common billing and service elements tied to the code, clarifies what CPT code 93745 represents in practice, and highlights content areas readers can expect: service definition, typical care setting, payer coverage landscape, and operational considerations such as data transmission and patient education workflows. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old man recently discharged after an acute myocardial infarction with severely reduced left ventricular ejection fraction (LVEF 28%) and transient ventricular arrhythmias. The cardiology team determines he is at high short-term risk for sudden cardiac death but is not yet a candidate for an implantable cardioverter-defibrillator (ICD) due to recent myocardial infarction, ongoing recovery, or awaiting revascularization. The provider performs initial setup and programming of a wearable cardioverter defibrillator (WCD) at an outpatient cardiology clinic or hospital-based device clinic. The clinical workflow includes verifying patient identity and indication, reviewing current medications and allergies, obtaining baseline vitals and 12-lead ECG, fitting the garment and electrodes, entering device parameters, recording baseline diagnostic data, transmitting baseline data to the device-monitoring central station, and providing structured patient education on device use, alarms, charging, and troubleshooting. Follow-up scheduling and remote monitoring enrollment are completed prior to discharge to home. Typical sites of service are hospital outpatient departments, cardiology clinics, or accredited device clinics with access to remote monitoring systems.
