Congenital pulmonary valve stenosis

This code describes a congenital heart defect characterized by a narrowing of the pulmonary valve, which obstructs blood flow from the right ventricle to the pulmonary artery. This stenosis can range from mild to severe, impacting the heart's ability to pump blood effectively to the lungs.

Apply this code when documentation clearly indicates a diagnosis of congenital pulmonary valve stenosis. This typically includes findings from echocardiograms, cardiac catheterization, or clinical examination confirming the presence and severity of the valve narrowing from birth.

• Differentiate from acquired pulmonary valve stenosis, which would be coded differently.
• Specify any associated congenital heart anomalies using additional codes if documented.
• Ensure the documentation explicitly states "congenital" to support the use of this code.
