CPT® Code 93613

Add-On Code

The CPT® Code 93613 refers to the procedure of intracardiac electrophysiologic three-dimensional (3D) mapping, which is performed to analyze and understand the electrical activity of the heart, particularly in cases of tachycardia. This procedure is essential for identifying the specific sites within the heart where tachycardia originates, as well as mapping the electrical pathways that the tachycardia follows. During this process, the physician utilizes specialized intra-cardiac catheters, which are placed in a separate, reportable procedure, to gather data from multiple electrodes positioned on the same catheter. The 3D mapping technique allows for simultaneous recordings, which are crucial for accurately reconstructing the electrical activity of the heart in three dimensions. This detailed mapping is instrumental in diagnosing and treating arrhythmias, as it provides a comprehensive view of the heart's electrical landscape. Following the mapping, the physician reviews all recordings and the generated 3D map to confirm the origin of the arrhythmia, investigate any additional arrhythmias, and compile a written report summarizing the findings and implications for further treatment.
