What 93609 covers
During an invasive electrophysiology study, the physician uses intracardiac catheter recordings and pacing information to map a tachycardia site within a ventricle. The mapping helps localize the area involved in the abnormal rhythm, commonly while evaluating or treating ventricular tachycardia. An electrophysiologist typically performs the service in a hospital electrophysiology laboratory alongside the primary diagnostic or ablation procedure. This code describes ventricular tachycardia-site mapping, rather than three-dimensional reconstruction of cardiac anatomy.
This is an add-on code and is reported only with an eligible primary procedure; Medicare treats it as paid within that procedure’s global period. Its physician fee schedule status is carrier priced (status C): CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for the claim. The service has professional and technical components. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical component, including equipment and staff, and no modifier represents the global service.

How to choose
- 936133D mappingIntracardiac electrophysiology
- 93613 describes intracardiac three-dimensional mapping. This code describes mapping a tachycardia site within a ventricle.
- 93612Ventricular pacingElectrophysiology study
- 93612 reports intraventricular pacing. This code reports mapping a ventricular tachycardia site, not pacing alone.

93609 billing questions
When is this code appropriate?
Use it for mapping a tachycardia site within a ventricle during an associated electrophysiology procedure. It is an add-on, not a stand-alone procedure code.
How does it differ from 93613?
This code describes mapping a ventricular tachycardia site. Code 93613 describes intracardiac three-dimensional mapping, a distinct mapping service.
Can it be reported by itself?
No. It must be reported with an eligible primary procedure and is paid within that procedure’s global period.
Which component modifiers can be used?
Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical component, including equipment and staff. Without either modifier, the code represents the global service.
How does Medicare determine payment?
The physician fee schedule status is carrier priced (status C). CMS publishes no national payment; the Medicare Administrative Contractor sets payment for each claim.
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.
