2025 ICD-10-CM code Q23.0
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Congenital malformations - Congenital malformations of the circulatory system Congenital malformations, deformations and chromosomal abnormalities (Q00-Q99) Feed
Congenital stenosis of the aortic valve, a narrowing of the aortic valve present at birth.
Medical necessity for this diagnosis code is established by the presence of symptoms (such as dyspnea, chest pain, syncope), documented hemodynamic compromise (such as reduced cardiac output), or echocardiographic evidence of significant aortic stenosis impacting cardiac function. Treatment necessity is determined by the severity of symptoms and hemodynamic effects.

In simple words: This code means the baby was born with a narrowed aortic valve.The aortic valve is a heart valve that lets blood flow out of the heart to the body.A narrowed valve makes it harder for blood to flow. This can cause problems depending on how severe it is.
Q23.0, Congenital stenosis of the aortic valve, refers to a narrowing of the aortic valve that is present from birth.This congenital defect restricts blood flow from the left ventricle to the aorta, potentially leading to various symptoms depending on the severity of the stenosis.The condition may range from mild, asymptomatic cases to severe, life-threatening situations requiring immediate medical intervention.Associated conditions might include left ventricular hypertrophy and other congenital heart defects.
Example 1: A newborn infant presents with cyanosis and respiratory distress.Echocardiography reveals severe congenital aortic stenosis. The infant requires immediate surgical intervention., A 10-year-old child is diagnosed with mild aortic stenosis during a routine check-up.They are asymptomatic and managed conservatively with regular cardiac monitoring., An adult patient experiences exertional chest pain and syncope. Diagnostic testing confirms moderate aortic stenosis.The patient is considered for valve repair or replacement surgery.
Detailed echocardiography report, cardiac catheterization findings (if performed), clinical examination notes, and any relevant imaging studies (chest X-ray, CT scan).
