Summary & Overview
CPT 93619: Intracardiac Electrophysiology Study with Multiple Electrode Catheters
CPT code 93619 denotes an intracardiac electrophysiology procedure in which multiple electrode catheters are inserted and repositioned in the right atrium, His bundle region, and right ventricle to evaluate abnormal cardiac rhythms. This code represents both technical and professional components of the diagnostic study and is integral to the identification and localization of arrhythmia sources. Nationally, electrophysiology studies are central to care pathways for syncope, palpitations, and complex arrhythmias and influence downstream therapeutic decisions such as ablation or device implantation.
Key payers included in analyses are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise synthesis of clinical context, common billing modifiers, typical sites of service, and the role of CPT code 93619 in the diagnostic workup of rhythm disorders. The publication provides benchmarks where available, summarizes relevant policy and coding considerations, and outlines coding relationships relevant to service lines that include cardiac electrophysiology and catheter-based diagnostics. Data not available in the input is noted when applicable.
Billing Code Overview
CPT code 93619 describes the insertion and repositioning of multiple electrode catheters in the right atrium, His bundle region, and right ventricle to evaluate abnormal heart rhythm disturbances. This service includes both the technical and professional components and is performed to map intracardiac electrical activity for diagnosis of arrhythmias.
-
Service type: Diagnostic intracardiac electrophysiology study involving multiple electrode catheters
-
Typical site of service: Cardiac catheterization laboratory or electrophysiology laboratory in an acute care hospital or ambulatory surgical center
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of hypertension and symptomatic palpitations is referred to electrophysiology for evaluation of recurrent supraventricular tachycardia. Noninvasive testing including ECG and ambulatory monitoring suggests intermittent narrow-complex tachycardia with episodes of fast regular rhythm and pauses. The electrophysiology study is scheduled in the cardiac electrophysiology lab. Under conscious sedation or monitored anesthesia care, the electrophysiologist obtains femoral venous access, advances multiple electrode catheters into the right atrium, the His bundle region, and the right ventricle, and repositions them as needed to record intracardiac electrograms, perform programmed stimulation, and map conduction pathways. The procedure includes both the technical component (catheter placement, fluoroscopy, recording equipment) and the professional component (arrhythmia interpretation, stimulation protocols, and reporting). Post-procedure monitoring occurs in a recovery area with observation for vascular complications, arrhythmia induction, or conduction disturbances before discharge or admission.
