About 93613: Intracardiac three-dimensional mapping
Report intracardiac three-dimensional electroanatomic mapping as an add-on when it is performed to guide a qualifying electrophysiology procedure, such as arrhythmia ablation.
An electrophysiologist uses a catheter-based mapping system to build a three-dimensional representation of cardiac anatomy and electrical activity. The map can show catheter position and activation patterns within a heart chamber, helping the physician locate arrhythmia pathways or tissue targeted during catheter ablation. This service is typically performed in a hospital electrophysiology lab during an invasive EP procedure.
Report 93613 only with a primary procedure, such as an ablation for supraventricular tachycardia, ventricular tachycardia, or atrial fibrillation; it is not a stand-alone service. The record should support that three-dimensional intracardiac mapping was performed and describe its role in the procedure. CMS treats this as an add-on code billed with the primary procedure and paid within that procedure’s global period. The mapping service is not selected by the number of map points or lesions documented.

93613 billing questions
Can 93613 be reported by itself?
No. It is an add-on code and must be reported with a qualifying primary procedure, such as an EP ablation.
Which ablation procedures are commonly paired with 93613?
It may accompany procedures such as 93653 for supraventricular tachycardia ablation, 93654 for ventricular tachycardia ablation, or 93656 for atrial fibrillation ablation when three-dimensional mapping is performed.
How is 93613 different from 93609?
93613 represents intracardiac three-dimensional mapping. Code 93609 describes a different intracardiac mapping service; choose based on the mapping performed, not simply because an ablation took place.
What documentation supports 93613?
Document the three-dimensional mapping performed, the cardiac area mapped, and how the map supported the EP procedure or ablation.
Are units based on map points or lesions?
No. Map points and ablation lesions are not separate units of 93613; report the add-on service with its associated primary procedure.
