CPT® Code 93609

Add-On Code

Intraventricular and/or intra-atrial mapping of tachycardia site(s) with catheter manipulation to record from multiple sites to identify origin of tachycardia (List separately in addition to code for primary procedure)

The CPT® Code 93609 refers to the procedure of intraventricular and/or intra-atrial mapping of tachycardia sites, which involves the use of catheter manipulation to record electrical activity from multiple sites within the heart. This procedure is essential for identifying the origin of tachycardia, a condition characterized by an abnormally fast heart rate. During this mapping process, intra-cardiac catheters are strategically placed within the heart chambers to capture detailed electrical signals. The standard technique employed is sequential mapping, where electrode-mounted catheters are repositioned systematically from one location to another within the heart. This allows for the collection of sequential recordings from each site, which are then analyzed to construct a comprehensive mapping of the tachycardia sites. The physician meticulously reviews these recordings and the resulting mapping to determine the precise electrical pathways involved in the tachycardia. A written report is generated to document the findings and support further clinical decision-making. It is important to note that this code is reported separately in addition to the code for the primary procedure performed during the arrhythmia induction process.
