Nonrheumatic aortic (valve) stenosis
ICD-10 I35.0 is a billable code used to indicate a diagnosis of nonrheumatic aortic (valve) stenosis.
Nonrheumatic aortic stenosis is a condition characterized by the narrowing of the aortic valve, which impedes blood flow from the heart into the aorta and subsequently to the rest of the body. This condition often arises from age-related calcific degeneration of the valve, leading to a tri-leaflet valve becoming stiff and less able to open fully. Patients may present with symptoms such as exertional dyspnea, angina, syncope, and heart failure due to the increased workload on the heart. The anatomy involved includes the aortic valve, left ventricle, and aorta, with potential downstream effects on the coronary arteries and systemic circulation. Disease progression can lead to severe left ventricular hypertrophy, heart failure, and increased mortality if left untreated. Diagnostic considerations include echocardiography to assess valve morphology and function, Doppler studies to measure pressure gradients, and cardiac catheterization in certain cases. Regular monitoring and timely intervention, such as valve replacement, are crucial for managing this condition effectively.

I35.0 covers nonrheumatic aortic stenosis, primarily due to age-related calcific degeneration or congenital anomalies. It does not include rheumatic causes or other types of aortic valve disorders.
I35.0 should be used when the aortic stenosis is confirmed to be nonrheumatic in nature, particularly when the etiology is degenerative or congenital, distinguishing it from rheumatic or other causes.
Documentation should include a detailed clinical assessment, echocardiographic findings indicating aortic stenosis, and any relevant history of valve disease. Imaging reports and treatment plans are also essential.
