CPT® Code 36455

The CPT® Code 36455 refers to the procedure known as exchange transfusion, specifically for patients other than newborns. This medical intervention involves the systematic removal of a patient's blood and simultaneous replacement with donor blood, aimed at correcting various hematological conditions. The exchange transfusion is typically performed using a two-catheter push-pull technique, which is a method that allows for the efficient and controlled exchange of blood. In this technique, the physician carefully selects an appropriate artery and vein for the procedure. Blood is withdrawn from the designated artery while donor blood is infused through the vein at an equal rate, ensuring that the patient's blood volume is maintained throughout the process. This procedure is crucial in managing conditions such as severe anemia, hemolytic disease, or other blood disorders where rapid correction of blood composition is necessary. The exchange transfusion can significantly improve the patient's overall blood quality and restore normal physiological function.
