Additional Info

• Classically there are four defects

• 1. pulmonary stenosis, narrowing of the exit from the right ventricle
• 2. a ventricular septal defect, a hole between the two ventricles
• 3. right ventricular hypertrophy, thickening of the right ventricular muscle
• 4. an overriding aorta, which allows blood from both ventricles to enter the aorta

• If it is associated with a genetic disorder combine with the disorder if known eg.. Downs Syndrome or Chromosomal abnormality, NOS

• Tetralogy of fallot

Alternate ICD10s to consider coding instead or in addition

• Heart NOS, congenital malformation
• Transposition of great vessels (corrected or not)
• Aortic valve or mitral valve, congenital malformation
• Atrial septal defect (ASD), congenital
• Ventricular septal defect (VSD), congenital
