CPT code 93609 identifies an invasive cardiac electrophysiology mapping procedure in which the clinician induces a rapid heartbeat and records electrical activity to locate the source of an arrhythmia. This diagnostic mapping is central to planning therapeutic interventions such as catheter ablation and is widely used across hospitals and specialized electrophysiology laboratories nationwide. The code matters nationally because accurate mapping guides high-cost downstream procedures and affects episode-of-care planning and resource use.

Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the role of CPT code 93609 in care pathways. The publication summarizes commonly observed billing patterns and benchmarks, highlights relevant policy and coverage considerations, and provides clinical context for how mapping with induced arrhythmia informs subsequent procedural decisions.
