Nonrheumatic pulmonary valve stenosis
ICD-10 I37.0 is a billable code used to indicate a diagnosis of nonrheumatic pulmonary valve stenosis.
Nonrheumatic pulmonary valve stenosis is a condition characterized by the narrowing of the pulmonary valve, which impedes blood flow from the right ventricle to the pulmonary artery. This condition can be congenital or acquired, with congenital cases being more common. Clinically, patients may present with symptoms such as exertional dyspnea, fatigue, and syncope, particularly during physical activity. The anatomy involved includes the right ventricle, pulmonary valve, and pulmonary artery. Over time, the increased pressure in the right ventricle can lead to right ventricular hypertrophy and potentially heart failure if left untreated. Diagnostic considerations include echocardiography, which is the primary tool for assessing the severity of stenosis, and cardiac catheterization in more complex cases. The progression of the disease can vary, with some patients remaining asymptomatic for years, while others may require surgical intervention, such as balloon valvuloplasty or valve replacement, depending on the severity of the stenosis and associated symptoms.

I37.0 specifically covers nonrheumatic pulmonary valve stenosis, which may be congenital or acquired, and does not include stenosis due to rheumatic heart disease.
I37.0 should be used when the pulmonary valve stenosis is confirmed to be nonrheumatic, differentiating it from rheumatic causes or other types of valve stenosis.
Documentation should include clinical findings, echocardiographic results, and any relevant history of congenital heart defects or previous interventions.
