CPT® Code 93602

The CPT® Code 93602 refers to the procedure known as intra-atrial recording, which is a diagnostic test used to assess the electrical activity within the atria of the heart. This procedure is particularly important for identifying conditions such as atrial flutter or atrial fibrillation, which may not be detectable through standard transthoracic electrocardiography (ECG). During the procedure, the physician obtains recordings from the atria, which are the upper chambers of the heart, to evaluate their electrical function. The process involves accessing the heart through veins, typically the femoral or jugular veins, where the skin is prepped, and the veins are punctured to insert sheaths. Using continuous fluoroscopic guidance, guidewires are carefully advanced into the heart, followed by the placement of catheters that are used to record the electrical activity. The recordings obtained are crucial for diagnosing arrhythmias and understanding the heart's electrical conduction system. After the procedure, the physician analyzes the recordings and generates a written report detailing the findings, which aids in determining the appropriate management for the patient’s condition.
