CPT code 0745T denotes an image-guided localization and mapping procedure that fuses imaging data with electrical recordings (such as ECG) to identify the precise site of an arrhythmia prior to a separately reportable radiation ablation. This preparatory mapping is a specialized service that supports noninvasive or minimally invasive cardiac ablation workflows and is relevant to centers offering advanced electrophysiology and cardiac radiation services.

Key national payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for CPT code 0745T, typical sites of service, and the role of the procedure within arrhythmia management pathways. The publication also summarizes common billing considerations and the typical supporting documentation needed for medical review.

This summary equips clinicians, coding staff, and policy professionals with concise context on where CPT code 0745T fits in clinical care and billing. It highlights the procedure's purpose — mapping and localization to prepare for radiation ablation — and outlines what the reader will learn: definitions, payer coverage landscape, documentation expectations, and the clinical workflow implications for facilities that provide image-guided arrhythmia localization nationally.
