CPT 0573T: Removal of Substernal Implantable Defibrillator Electrode
CPT code 0573T captures the surgical removal of a previously placed substernal implantable defibrillator electrode following detachment from the pulse generator. This code is specific to explantation of substernal leads and is relevant for facilities and clinicians managing patients with implantable cardioverter-defibrillator systems that include substernal lead placement. Nationally, precise coding for lead removal affects claims adjudication, clinical documentation, and comparative utilization for complex device management.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for substernal lead explantation, expectations for typical sites of service, and the operational implications of coding this procedure. The publication outlines common billing modifiers used with complex surgical device procedures and summarizes payer coverage patterns where available. It also highlights benchmarks and policy updates relevant to device explantation, and provides guidance on documentation elements that support correct use of CPT code 0573T.
This content is intended for a national audience of billing professionals, clinicians, and revenue cycle managers who need clear information on coding, clinical context, and payer considerations for substernal implantable defibrillator electrode removal. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0573T describes removal of a previously placed substernal implantable defibrillator electrode after first detaching it from the pulse generator. The procedure involves explantation of a substernal defibrillator lead that had been implanted beneath the sternum.
-
Service type: Surgical lead explantation of a substernal implantable defibrillator electrode
-
Typical site of service: Hospital operating room or inpatient surgical setting; may also occur in an ambulatory surgery center depending on clinical status and facility capability
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who previously had a substernal implantable cardioverter-defibrillator (ICD) electrode placed for prevention of sudden cardiac death and now requires removal of that substernal lead. Indications for removal include lead malfunction (fracture, insulation breach), infection involving the device or pocket with potential extracardiac extension, chronic pain or erosion at the lead site, or need for lead extraction prior to device revision or upgrade. The procedure begins with preoperative evaluation including history, device interrogation, chest imaging (chest radiograph and often CT for substernal leads), and review of antimicrobial therapy if infection is present. In the operating room or electrophysiology lab under general anesthesia or monitored anesthesia care, the generator is exposed and detached from the substernal electrode. The provider then performs a substernal lead extraction using direct traction, specialized extraction tools, or an open approach as indicated by lead dwell time, adhesions, and patient anatomy. Intraoperative monitoring includes continuous ECG, fluoroscopy, and availability of surgical backup for sternotomy if needed. Postoperative workflow includes device interrogation, wound care, antimicrobial therapy when indicated, and short-term inpatient observation for complications such as bleeding, pneumothorax, cardiac injury, or mediastinal infection. Typical site of service is the hospital operating room or hospital-based electrophysiology/catheterization laboratory equipped for invasive lead extraction and emergent surgical intervention. Service type: surgical lead removal (extraction) procedure of a previously placed substernal defibrillator electrode.
