Summary & Overview
CPT 93613: Electroanatomic Mapping with Arrhythmia Induction
CPT code 93613 denotes electrophysiology mapping with induction of arrhythmia and construction of a three-dimensional electroanatomic map to localize the origin of abnormal cardiac electrical activity. This procedure is a key diagnostic and pre-therapeutic step for patients with complex atrial or ventricular arrhythmias and informs subsequent ablation or device strategies. Nationally, the code matters for hospitals and cardiac centers because it drives resource use, impacts procedural scheduling in electrophysiology labs, and factors into payer coverage and prior authorization workflows.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of the clinical role of the procedure, typical sites of service, and the payer mix most commonly responsible for coverage. The publication outlines benchmarking context where available, notes common modifiers used with the service, and highlights the operational implications for electrophysiology programs.
This summary provides clinicians, coding professionals, and policy analysts with the clinical context and billing scope for 93613, helping stakeholders understand where the code fits in care pathways for arrhythmia diagnosis and management. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 93613 describes a procedure in which the provider induces a rapid heartbeat (arrhythmia) and uses multiple intracardiac and/or body-surface electrodes to construct a three-dimensional electroanatomic map of the heart in order to identify the origin of abnormal electrical activity. This mapping guides diagnostic localization and targeted treatment of arrhythmias.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with symptomatic, recurrent paroxysmal supraventricular tachycardia or suspected focal atrial tachycardia is referred to electrophysiology for invasive evaluation and catheter ablation planning. The patient presents with palpitations, presyncope, or documented narrow-complex tachycardia on ambulatory monitor despite medical therapy. After informed consent and pre-procedure evaluation (including anticoagulation management, imaging as indicated, and anesthesia assessment), the electrophysiology team induces the clinical tachycardia using programmed stimulation and/or isoproterenol infusion. Multiple intracardiac electrode catheters are placed and a three-dimensional electroanatomic mapping system is used to create a detailed map of electrical activation to identify the arrhythmia focus or circuit. This mapping procedure is performed in the cardiac catheterization lab or electrophysiology suite under moderate sedation or general anesthesia with continuous hemodynamic and fluoroscopic monitoring. Findings from the mapping guide targeted ablation, device placement, or further diagnostic maneuvers during the same encounter as clinically indicated.
