2025 ICD-10-CM code Q24.4
(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 subaortic stenosis is a narrowing of the aortic valve located below the aortic valve.
Modifiers are not applicable to ICD-10 codes.
Medical necessity for diagnosis and treatment of Q24.4 is established based on the presence of symptoms (shortness of breath, chest pain, syncope, fatigue), the severity of the stenosis, and the impact on the patient's quality of life and hemodynamics.Severity of stenosis should be documented to support medical necessity.
The clinical responsibility for a patient with Q24.4 would rest with a cardiologist, cardiac surgeon, and potentially other specialists depending on the complexity of the case and associated conditions.Initial diagnosis and management are usually under the cardiologist's care, with surgical intervention (if necessary) overseen by a cardiac surgeon.

In simple words: Congenital subaortic stenosis is a birth defect affecting the heart's main artery (aorta). The opening to this artery is narrowed, making it harder for the heart to pump blood efficiently. This can cause tiredness, breathlessness, and chest pain but may also have no noticeable symptoms.
Congenital subaortic stenosis (Q24.4) refers to a narrowing of the aorta immediately below the aortic valve. This congenital heart defect restricts blood flow from the left ventricle to the aorta, leading to reduced blood circulation throughout the body.The severity varies, ranging from mild to severe, and can present with symptoms such as shortness of breath, chest pain, and fatigue, or it can be asymptomatic. Diagnosis often involves echocardiography, cardiac catheterization, and other imaging techniques. Treatment options depend on the severity and may include medication, surgical procedures (e.g., valvotomy, valvuloplasty), or interventional cardiac catheterization.
Example 1: A newborn infant is diagnosed with congenital subaortic stenosis via echocardiogram during a routine examination. The severity is mild, and the treatment plan involves close monitoring with regular echocardiogram follow-ups., A 5-year-old child presents with shortness of breath and fatigue.Echocardiography reveals moderate subaortic stenosis.The child undergoes a balloon valvuloplasty procedure to widen the narrowed aortic valve., A teenager experiences chest pain and syncope.Cardiac catheterization confirms severe subaortic stenosis, necessitating open-heart surgery for valve repair or replacement.
Detailed echocardiogram reports, cardiac catheterization reports (if performed), medical history including symptoms and family history of heart conditions, treatment plans, and relevant notes on patient progress are needed.Documentation should align with the severity and treatment plan (medical management versus surgical intervention).
