Electrophysiology
About 93655: Additional discrete arrhythmia ablation
Reports catheter ablation of an additional, distinct arrhythmia mechanism during a primary ablation procedure, such as atrial flutter treated during an atrial fibrillation ablation.
An electrophysiologist reports this code when a catheter ablation session treats an arrhythmia mechanism distinct from the session’s primary ablation target. For example, an atrial flutter circuit may be treated during a procedure whose primary target is atrial fibrillation. The separate target must represent another mechanism, not simply additional lesions directed at the primary arrhythmia. These procedures are typically performed in a cardiac electrophysiology lab using intracardiac catheters and electrophysiologic mapping.
Report 93655 only with a qualifying primary ablation code: 93653, 93654, or 93656. The record should identify the separate arrhythmia mechanism and document its evaluation and ablation. This is an add-on service, not a stand-alone claim line; CMS pays it within the primary procedure’s global-period framework. Report the additional mechanism treated, rather than counting individual lesions as separate units.

How this local rate is calculated
Each RVU component is multiplied by its own geographic practice cost index (GPCI). The three adjusted components are added, then multiplied by the conversion factor. These are the inputs used for 93655 in Alabama.

93655 billing questions
Which primary codes can accompany 93655?
Report it with 93653, 93654, or 93656. It is an add-on code and cannot stand alone.
Can 93655 be used for atrial flutter treated during an atrial fibrillation ablation?
Yes, when the flutter is a separately identified arrhythmia mechanism treated during the session, in addition to the primary atrial fibrillation target.
How is 93655 different from 93657?
93655 addresses ablation of a distinct arrhythmia mechanism. 93657 addresses additional atrial ablation for atrial fibrillation after the primary AF ablation.
Is 93655 reported for each lesion?
No. The code represents treatment of an additional discrete mechanism, not the number of lesions delivered.
What documentation supports 93655?
Document the separate arrhythmia mechanism, the findings that identify it, and the ablation performed for that target, alongside the primary ablation.
How does CMS handle payment for this add-on?
CMS pays 93655 within the primary procedure’s global-period framework. The code must be reported with a qualifying primary ablation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
