Summary & Overview
CPT 0574T: Reposition Substernal Implantable Defibrillator–Pacing Electrode
CPT code 0574T covers surgical repositioning of a previously implanted substernal implantable defibrillator–pacing electrode and reattachment to a pulse generator. The procedure is clinically important where subcutaneous or transvenous electrode approaches are not feasible, offering an alternative pathway for defibrillation and pacing in select patients. Nationally, this code reflects specialized cardiac device management and has implications for hospital procedural coding, device-related quality measurement, and reimbursement for advanced electrophysiology services.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a concise overview of the clinical scenario the code represents, typical settings where the service is performed, and which major payers commonly cover these services. The publication provides benchmarks and coding context, policy and coverage notes relevant to payers, and clinical background on when substernal electrodes may be used versus subcutaneous or transvenous systems.
This summary is intended for coding managers, cardiology practice leaders, revenue cycle professionals, and policy analysts seeking a national-level briefing on the role of CPT code 0574T in contemporary electrophysiology care and payer coverage considerations.
Billing Code Overview
CPT code 0574T describes the repositioning of a previously placed substernal implantable defibrillator–pacing electrode and its attachment to a pulse generator. This procedure is performed when a substernal electrode, implanted beneath the sternum, requires surgical repositioning and reconnection to the device that senses and regulates the heart rhythm.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with ischemic cardiomyopathy and recurrent ventricular tachycardia presents after prior attempts at subcutaneous and transvenous lead placement were deemed infeasible due to limited vascular access and infection risk. The electrophysiology team schedules the patient for a procedure to reposition a previously placed substernal implantable defibrillator–pacing electrode and attach it to a pulse generator. Typical workflow includes preoperative device interrogation and imaging review, informed consent discussing risks of bleeding, infection, lead displacement, and device malfunction, perioperative antibiotic prophylaxis, procedural anesthesia (general or monitored anesthesia care), surgical exposure of the substernal pocket and generator site, careful dissection to locate the previously tunneled substernal electrode, lead assessment and repositioning as needed, secure attachment to the pulse generator, intraoperative device testing including sensing and defibrillation threshold testing as indicated, wound closure, and postoperative device programming and chest radiograph to document lead position. Typical site of service is an operating room or cardiac electrophysiology procedure suite in an acute care hospital. Typical patient scenario: symptomatic ventricular arrhythmia or device malfunction in a patient with limited venous access, prior device infection, or anatomical considerations making substernal electrode the optimal approach.
