Direct Heart Surface Mapping During Open-Heart Surgery

Maryland rates for HCPCS 93631

This covers mapping the heart's electrical activity by placing electrodes directly on the outer and inner surfaces of the heart during open-heart surgery, done to locate the source of an abnormal heart rhythm in real time. Because it is performed with the heart exposed during an operation, it gives very precise, direct information that guides the surgical treatment of the rhythm problem. This is a specialized step within a larger heart surgery.
