Summary & Overview
CPT 93618: Catheter Insertion to Induce Arrhythmia
CPT code 93618 denotes the insertion of a catheter specifically to induce an arrhythmia, a targeted cardiac electrophysiology procedure used to reproduce arrhythmic events for diagnostic mapping or to facilitate treatment. Nationally, this code is important because it captures a focused invasive step in electrophysiology studies and ablation workflows that can affect coding specificity, billing pathways, and utilization measurement across hospital and outpatient settings. Key payers considered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. This publication provides readers with a concise overview of clinical context, typical sites of service, and the operational role of the code within electrophysiology care. It outlines what to expect in benchmarking and payer coverage landscapes, highlights policy-relevant considerations for reimbursement coding consistency, and clarifies the clinical intent captured by the code. The content is aimed at billing professionals, hospital administrators, and clinicians involved in cardiac electrophysiology who need a clear description of the code’s purpose, how it fits into procedural sequences, and what national payers commonly recognize. Data gaps in associated taxonomies, specific ICD-10 pairings, and related codes are noted when input data are not available.
Billing Code Overview
CPT code 93618 describes the insertion of a catheter for the purpose of inducing an arrhythmia. This procedure is an interventional cardiac electrophysiology service performed to provoke or reproduce an arrhythmia for diagnostic evaluation, mapping, or to facilitate therapeutic intervention.
-
Service type: Cardiac electrophysiology procedure involving catheter insertion to induce arrhythmia
-
Typical site of service: Electrophysiology laboratory or cardiac catheterization suite; inpatient or outpatient hospital settings are common depending on clinical context

Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old referred to an electrophysiology (EP) lab for evaluation of recurrent palpitations, syncope, or supraventricular tachycardia not fully characterized by surface ECG and ambulatory monitoring. The procedure involves conscious sedation or general anesthesia; vascular access is obtained (femoral venous typically) and one or more diagnostic catheters are introduced into the heart. The provider intentionally induces an arrhythmia by programmed electrical stimulation or burst pacing using the catheter to reproduce clinical tachycardia for diagnostic mapping, to determine arrhythmia mechanism, to assess the need for ablation, or to test device/medication efficacy. Typical workflow includes pre-procedure consent and anticoagulation assessment, intra-procedural monitoring with intracardiac electrograms and fluoroscopy, arrhythmia induction and recording, and post-procedure recovery with rhythm monitoring before discharge or admission if complications occur.
