CPT code 93662: Intracardiac ultrasound, EP procedure imaging2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 93662 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93662 covers

Intracardiac echocardiography uses an ultrasound catheter positioned inside the heart to produce real-time images during an electrophysiology procedure. An electrophysiologist commonly uses the images to assess cardiac anatomy and guide catheter work, including ablation or access across the atrial septum. The service is generally performed in an electrophysiology lab, often during a catheter ablation procedure.

93662 is an add-on code and is reported with a primary procedure; Medicare treats it as carrier priced, status C. CMS publishes no national physician fee schedule payment for this code, so the Medicare Administrative Contractor sets payment for each claim. The service falls within the primary procedure’s global period. Modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and reporting without either modifier represents the global service.
