CPT code 33213 covers the insertion of a dual pacemaker pulse generator connected to previously placed leads. The code applies to procedures where the pulse generator (the device that creates electrical impulses) is implanted or replaced while the existing atrial and ventricular leads remain in situ. Nationally, this service is a routine component of cardiac electrophysiology care and influences device utilization, facility resource planning, and outpatient versus inpatient site-of-service decisions.

Key payers in the coverage landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for generator replacement or implantation with existing leads, typical sites of service (hospital OR or ambulatory surgery center), and the billing implications tied to device-based cardiac procedures. The publication presents national benchmarks where available, summarizes relevant policy and coverage considerations affecting payment and site-of-care settings, and outlines common clinical scenarios that drive use of this code. Data not available in the input will be noted as such elsewhere in the report.
