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.
