CPT code 93610: Intracardiac pacing, atrial chamber2026 Medicare rate & RVUs in Missouri
Intracardiac electrical stimulation of the atrium is reported during an electrophysiology study to assess atrial response and conduction or evaluate arrhythmias.
CMS doesn’t publish an office rate for 93610 in Missouri.
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.

How to choose
- 93602Atrial recordingIntracardiac
- 93602 describes recording electrical activity in the atrium; 93610 describes delivering electrical stimuli to the atrium.
- 93612Ventricular pacingElectrophysiology study
- 93612 is for intracardiac ventricular pacing. Choose 93610 when the paced chamber is the atrium.
- 93618Arrhythmia inductionElectrical pacing
- 93618 identifies electrical pacing to induce an arrhythmia; 93610 identifies intra-atrial pacing.
- 93620EP evaluationRight-sided pacing
- 93620 describes a comprehensive EP evaluation, while 93610 identifies intra-atrial pacing as a specific service.
93610 billing questions
How is 93610 different from intra-atrial recording?
93610 identifies electrical stimulation delivered to the atrium. Code 93602 describes recording atrial electrical activity rather than pacing.
When should 93612 be considered instead?
Use 93612 for intracardiac pacing of the ventricle. Code 93610 is for pacing the atrium.
Can modifier 26 or TC be reported?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion. Without either modifier, the code represents the global service.
How does Medicare price 93610?
Status C means CMS publishes no national payment amount for the physician fee schedule. The Medicare Administrative Contractor prices each claim.
How does 93610 differ from a comprehensive EP evaluation?
Codes 93619 and 93620 describe comprehensive EP evaluations, while 93610 identifies intra-atrial pacing as a specific service.
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.
