CPT® Code 62294

The procedure described by CPT® Code 62294 involves an injection procedure that targets the arterial occlusion of an arteriovenous malformation (AVM) located in the spinal region. An AVM is a complex vascular anomaly that consists of a tangle of abnormal blood vessels, specifically arteries and veins, which are interconnected by abnormal channels known as fistulas. These malformations can be congenital, meaning they are present at birth, or acquired due to factors such as trauma or infection that lead to the formation of abnormal connections between arteries and veins. The goal of this endovascular occlusion procedure is to effectively block the abnormal blood flow associated with the AVM, thereby reducing the risk of complications such as hemorrhage or neurological deficits. The procedure typically involves accessing the femoral artery, through which a catheter is navigated to the spinal artery supplying the AVM. Once in position, various materials, including liquid tissue adhesives, micro-coils, or micro-particles, are injected to occlude the affected artery. This intervention is crucial for managing the risks associated with spinal AVMs and improving patient outcomes.
