Summary & Overview
CPT 0515T: Wireless Cardiac Stimulator Implantation with LV Electrode
CPT code 0515T reports the implantation of a wireless cardiac stimulation system in which a generator (battery) and a transmitter are placed in separate subcutaneous pockets, connected by a tunneled cable, and a wireless electrode is inserted into the left ventricle with testing and programming adjustments performed. This procedure represents an advanced device-based therapy for patients requiring left ventricular electrical support or resynchronization and has implications for device utilization, facility resource planning, and payer coverage policies at a national level.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical and billing context for CPT code 0515T, national benchmarking metrics where available, common billing modifiers and situational coding considerations, and links to policy and coverage trends affecting device implantation services. The publication also summarizes typical sites of service and clinical scenarios prompting use of this code.
Where specific data elements are absent from the source input, the report notes those as unavailable rather than inferred. The content is intended to inform revenue cycle teams, device program administrators, and clinical coders about the operational and payer-related aspects of billing for wireless left ventricular stimulator implantation under CPT code 0515T.
Billing Code Overview
CPT code 0515T describes the placement of a wireless cardiac stimulation system consisting of a subcutaneously implanted generator (battery) and a separate transmitter, each seated in its own subcutaneous pocket and connected by a tunneled cable. The procedure also includes insertion of a wireless electrode into the left ventricle, intraoperative testing of the system, and adjustment of device programming. Imaging supervision and interpretation, if performed, are included in this code.
-
Service type: Implantation of a wireless cardiac stimulator system with leadless left ventricular electrode placement and intraoperative system testing and programming
-
Typical site of service: Hospital operating room or cardiac catheterization laboratory (inpatient or outpatient procedural setting)
Clinical & Coding Specifications
Clinical Context
A 72-year-old patient with symptomatic heart failure and reduced ejection fraction presents for implantation of a wireless cardiac stimulation system that provides pacing from a left ventricular endocardial electrode paired with an external generator/transmitter. The patient has recurrent dyspnea and fatigue despite guideline-directed medical therapy and is evaluated by a heart failure cardiologist and electrophysiologist. Pre-procedure workup includes transthoracic echocardiography, review of prior coronary angiography, anticoagulation assessment, and informed consent. On the day of the procedure, the patient undergoes conscious sedation or general anesthesia in a catheterization laboratory or hybrid operating room. The electrophysiologist creates two separate subcutaneous pockets: one for the generator (battery) and one for the transmitter, tunnels a connecting cable subcutaneously, and obtains trans-septal or retrograde arterial access to advance and deploy a wireless left ventricular endocardial electrode. After securing the electrode, the system is tested for sensing, pacing thresholds, and impedance. Device programming adjustments are performed to optimize pacing parameters and ensure appropriate communication between the electrode and the external transmitter/generator. Peri-procedural imaging (fluoroscopy) and hemodynamic monitoring are used as needed and are included in the global service when performed. Post-procedure monitoring includes device interrogation, wound checks, and short-term telemetry before discharge to home or a monitored inpatient bed.

78 | Return to operating/procedure room for a related procedure during the postoperative period | Use when the patient returns for a related unplanned procedure tied to 0515T during the global period. |
