CPT code 93624: EP follow-up study, pacing and recording2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 93624 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 93624 covers

An electrophysiology follow-up study uses intracardiac pacing and recording to assess the effect of prior arrhythmia treatment. The electrophysiologist tests whether the arrhythmia can be induced or remains inducible after therapy, such as medication or catheter ablation. This is a follow-up assessment, rather than a comprehensive diagnostic EP evaluation performed to investigate an arrhythmia. The study is typically performed in an electrophysiology laboratory.

Medicare assigns this code physician fee schedule status C, carrier priced: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The service may be reported globally or split into professional and technical components with modifier 26 or TC, respectively; the unmodified code represents the global service. The 0-day global period includes same-day preoperative and postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others are paid at 50%. Modifier 50 is inappropriate because a bilateral adjustment does not apply.
