Below is a list summarizing the CPT codes for repair procedures for single ventricle and other complex cardiac anomalies.
CPT Code 33600
CPT 33600 describes closure of atrioventricular valve (mitral or tricuspid) by suture or patch.
CPT Code 33602
CPT 33602 describes closure of the semilunar valve (aortic or pulmonary) by suture or patch.
CPT Code 33606
CPT 33606 describes the Damus-Kaye-Stansel procedure, which is an anastomosis of the pulmonary artery to the aorta.
CPT Code 33608
CPT 33608 describes the construction or replacement of a conduit from the right or left ventricle to the pulmonary artery for the repair of a complex cardiac anomaly other than pulmonary atresia with ventricular septal defect.
CPT Code 33610
CPT 33610 describes the repair of complex cardiac anomalies, such as single ventricle with subaortic obstruction, through surgical enlargement of ventricular septal defect.
CPT Code 33611
CPT 33611 describes the repair of double outlet right ventricle with intraventricular tunnel repair.
CPT Code 33612
CPT 33612 describes repair of double outlet right ventricle with intraventricular tunnel repair, as well as repair of right ventricular outflow tract obstruction.
CPT Code 33615
CPT 33615 describes the repair of complex cardiac anomalies, such as tricuspid atresia, through closure of an atrial septal defect and anastomosis of the atria or vena cava to the pulmonary artery in a simple Fontan procedure.
CPT Code 33617
CPT 33617 describes the repair of complex cardiac anomalies, such as single ventricle, by a modified Fontan procedure.
CPT Code 33619
CPT 33619 describes repair of single ventricle with aortic outflow obstruction and aortic arch hypoplasia (hypoplastic left heart syndrome) such as the Norwood procedure.
CPT Code 33620
CPT 33620 describes the application of right and left pulmonary artery bands (eg, hybrid approach stage 1).
CPT Code 33621
CPT 33621 describes transthoracic insertion of a catheter for stent placement, followed by catheter removal and closure using a hybrid approach stage 1.
CPT Code 33622
CPT 33622 describes a complex cardiac anomaly reconstruction with palliation of single ventricle, creation of cavopulmonary anastomosis, and removal of right and left pulmonary bands.
