Repair of pulmonary atresia with ventricular septal defect, by construction or replacement of conduit from right or left ventricle to pulmonary artery.
Modifiers may be applicable to indicate specific circumstances of the procedure (e.g., increased procedural services, multiple procedures, etc.).
Medical necessity is established by the presence of pulmonary atresia and ventricular septal defect, which compromise normal blood flow and oxygenation, requiring surgical intervention for survival and improved quality of life.
The surgeon performs the procedure, including prepping the patient, establishing cardiopulmonary bypass, creating the conduit, closing defects, and closing the incision.
In simple words: This surgery fixes a birth defect where the heart's pulmonary valve and the wall between the lower heart chambers haven't formed correctly. The surgeon creates a new pathway for blood to flow from the heart to the lungs.A heart-lung machine is used during the operation.
The provider surgically repairs pulmonary atresia, a congenital anomaly where the pulmonary valve is underdeveloped, along with a ventricular septal defect. This involves creating a conduit between a ventricle (right or left) and the pulmonary artery.The procedure includes establishing cardiopulmonary bypass, constructing the conduit, closing the ventricular and atrial septal defects, and closing the surgical incision.
Example 1: A newborn is diagnosed with pulmonary atresia and a ventricular septal defect. This complex condition requires surgical intervention to create a pathway for blood to flow to the lungs., An infant with cyanosis (bluish skin discoloration) due to insufficient blood flow to the lungs is found to have pulmonary atresia and VSD. Code 33920 is used for the surgical repair involving conduit construction., A child with a combination of pulmonary atresia and ventricular septal defect undergoes surgical repair with cardiopulmonary bypass to establish normal blood circulation.
Documentation should include operative report detailing the surgical technique, pre- and post-operative diagnoses, use of cardiopulmonary bypass, type of conduit used, closure of defects, and any complications.
