Summary & Overview
CPT 0571T: Implant or Replace ICD System With Substernal Electrodes
CPT code 0571T designates implantation or replacement of an implantable cardioverter–defibrillator (ICD) system using substernal electrodes, with necessary intraoperative testing and programming. Substernal ICD systems are an emerging alternative when subcutaneous or transvenous leads are contraindicated or not feasible, making this code relevant for hospitals, electrophysiology practices, and payers as adoption of alternative lead approaches expands nationally. The code matters for device-related surgical billing, perioperative resource planning, and policy decisions around coverage for novel ICD lead placements.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find context on the clinical use case for substernal ICD systems, the typical sites of service where these procedures occur, and the types of documentation and testing activities reflected by the code. The publication summarizes benchmarks and payment practice implications, highlights coding and clinical considerations for implantation and replacement procedures, and notes where input data for specific payers or taxonomies was not provided. This overview equips administrators, coding professionals, and policy analysts with a concise reference for understanding the purpose and setting of CPT code 0571T and where to look for additional payer-specific coverage guidance.
Billing Code Overview
CPT code 0571T describes replacement or implantation of an implantable cardioverter–defibrillator (ICD) system that uses one or more substernal electrodes, including intraoperative testing and programming of the system. The procedure addresses cardiac rhythm disorders by sensing and delivering therapy to regulate heart rate when subcutaneous or transvenous electrode approaches are not feasible.
Service type: Device implantation/replacement with device testing and programming
Typical site of service: Hospital inpatient or hospital outpatient surgical setting, including electrophysiology laboratories equipped for device implantation and intraoperative device testing.
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with ischemic cardiomyopathy, left ventricular ejection fraction 28%, and a history of sustained ventricular tachycardia presents for implantation of a new implantable cardioverter–defibrillator (ICD) system using one or more substernal electrodes. The patient previously had failed transvenous lead placement due to venous occlusion and was not an optimal candidate for a subcutaneous-only system due to body habitus and prior device infections.
Pre-procedure workflow includes preoperative cardiology evaluation, review of prior imaging and venous patency, informed consent specific to substernal electrode placement, and perioperative anesthesia assessment. The procedure is performed in an electrophysiology lab or hybrid operating room with fluoroscopic and intracardiac or epicardial mapping capability. The operator creates a substernal tunnel, places one or more substernal electrodes connected to a subcutaneous pulse generator, performs intraoperative sensing and defibrillation threshold testing as indicated, and programs the device. Postoperative workflow includes device interrogation, chest radiograph as indicated, wound care instructions, and short-term remote monitoring enrollment. Typical site of service is an inpatient or outpatient hospital-based electrophysiology suite or ambulatory surgical center with cardiac monitoring capability.
