CPT code 93610: Intracardiac pacing, atrial chamber2026 Medicare rate & RVUs

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

What 93610 covers

During an invasive cardiac electrophysiology study, the electrophysiologist delivers controlled electrical stimuli to atrial tissue through an intracardiac electrode catheter. These pacing maneuvers help assess the atrial electrical response and conduction and may help evaluate or provoke arrhythmias. The service is performed in a cardiac catheterization or electrophysiology laboratory, generally as part of a study that also involves catheter placement and intracardiac monitoring. This code identifies atrial pacing, not recording alone, ventricular pacing, or a complete EP evaluation.

For Medicare physician fee schedule purposes, 93610 has status C: CMS publishes no national payment, and the Medicare Administrative Contractor prices each claim. It is a diagnostic test with separately reportable professional (modifier 26) and technical (modifier TC) portions; reporting without either modifier represents the global service. The code has a 0-day global period, so same-day preoperative and postoperative care is included. Documentation should identify the atrial pacing performed and support the interpretation when billing the professional portion.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
