Repair Of Upper Heart Chamber Wall Defect

Michigan rates for HCPCS 33645

Open-heart surgery to close a hole in the wall between the two upper chambers of the heart, in the area where large veins enter. If veins returning blood from the lungs are draining into the wrong chamber, they are rerouted into the correct one during the same operation. Closing the hole stops oxygen-rich and oxygen-poor blood from mixing and relieves the extra load on the right side of the heart.
