The code for an electrophysiological procedure does not include which of the following?

The code for an electrophysiological procedure does not include ablation. Electrophysiological procedures focus on evaluating and treating electrical conduction issues within the heart. While ablation is a common treatment option included in certain electrophysiological coding, it is categorized separately due to its specific procedural nature and often requires distinct coding guidelines.

Electrocardiogram (ECG) is essential in identifying arrhythmias and assessing heart function, and thus it is typically included within the scope of electrophysiological studies. Cardiac monitoring refers to ongoing observation of the heart's electrical activity, which is relevant during electrophysiological evaluations. Heart mapping, particularly in the context of electrophysiology, involves identifying the source of arrhythmias and is a critical component of many procedures performed. Therefore, ablation stands out as the choice that does not belong in the grouping of activities classified under electrophysiological procedure coding.
