Norwood Sano Procedure

A patient with hypoplastic left heart syndrome (HLHS) presented for first stage palliation (Norwood procedure) where the outflow from the right ventricle (pulmonary artery) and the outflow from the left ventricle (aorta) are connected side to side. An additional connection is made with either a Sano or Blalock-Taussig (BT) shunt for the blood flow into the lungs. During this procedure, the patient was placed on cardiopulmonary bypass, and a pulmonary homograft patch was utilized to augment the aortic arch reconstruction and a right ventricular to pulmonary artery (RV-PA) conduit (Sano shunt) was utilized to create a pathway for the blood to flow into the lungs. What codes are assigned for a Stage 1 Norwood Sano procedure with a RV-PA conduit? ...
