CPT code 93619: EP evaluation, without arrhythmia induction2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 93619 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 93619 covers

An invasive EP study uses intracardiac electrode catheters to assess cardiac conduction and rhythm by recording from the right atrium, right ventricle, and His bundle, with pacing and recording. Electrophysiologists typically perform it in a hospital EP laboratory when evaluating suspected arrhythmias or conduction abnormalities, including unexplained palpitations or syncope. This code represents the comprehensive right-sided evaluation without arrhythmia induction or attempted induction, which distinguishes it from 93620.

Medicare lists 93619 as carrier priced (status C): CMS publishes no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for each claim. The diagnostic test may be billed globally or by component: modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Its 0-day global period includes same-day preoperative and postoperative care. Medicare's standard multiple-procedure reduction applies when multiple procedures are performed in the same session.
