Summary & Overview
CPT 93662: Intracardiac Echocardiography, Add-On Image Guidance
CPT code 93662 is an add-on code for intracardiac echocardiography used to provide real-time ultrasound imaging of cardiac structures during a therapeutic or diagnostic cardiac intervention. As a guidance modality, intracardiac echocardiography supports procedural safety and precision during electrophysiology and structural heart procedures, and its use is increasingly relevant as complex catheter-based interventions expand nationally. The code captures the imaging service performed concurrently with another primary procedure rather than a standalone service.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coverage considerations and billing context across major payers, common modifier interactions, and clinical context about when intracardiac echocardiography is typically employed. The publication summarizes national billing benchmarks where available, highlights policy updates that affect add-on imaging codes, and outlines practical documentation elements that support accurate coding and claims adjudication.
This summary is written for clinicians, coding professionals, and policy analysts seeking concise information about the clinical role and billing context of CPT code 93662. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 93662 describes an add-on intracardiac echocardiography procedure performed by a provider to image the interior structures of the heart using ultrasound while a therapeutic or diagnostic cardiac intervention is underway. This imaging technique provides real-time visualization of cardiac anatomy and device position to guide procedures.
Service type: Image guidance during cardiac intervention
Typical site of service: Cardiac catheterization laboratory or interventional cardiology suite
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old male with symptomatic atrial fibrillation undergoing catheter ablation. The electrophysiologist performs transseptal puncture and delivers radiofrequency energy to isolate the pulmonary veins. During the procedure, intracardiac echocardiography (IC E) using the add-on code 93662 is used to visualize cardiac structures, guide transseptal access, monitor catheter position, and detect pericardial effusion in real time. The clinical workflow includes pre-procedure consent and imaging review, vascular access in the electrophysiology lab, insertion of the intracardiac ultrasound catheter via femoral venous access, continuous imaging during mapping and ablation, and post-procedure monitoring in the recovery area. Typical site of service is an ambulatory surgical center or hospital-based electrophysiology laboratory. The service type is an intra-procedural imaging add-on performed by the operator to support diagnostic or therapeutic intracardiac interventions.
