Mitral valve stenosis and aortic valve stenosis

This code signifies the co-occurrence of two distinct valvular heart diseases: narrowing of the mitral valve and narrowing of the aortic valve. Both conditions impede blood flow through the heart, potentially leading to symptoms like shortness of breath, fatigue, and chest pain.

Apply this code when documentation explicitly states the presence of both mitral valve stenosis and aortic valve stenosis. This diagnosis is typically supported by echocardiogram findings, cardiac catheterization reports, and physician notes detailing the severity and impact of both stenotic lesions.

• Ensure both mitral and aortic stenosis are clearly documented; do not assume co-occurrence from general valvular heart disease.
• If the documentation specifies the etiology (e.g., rheumatic), consider additional codes for the underlying cause.
• This code represents a combined condition; avoid separate codes for isolated mitral stenosis and isolated aortic stenosis when both are present and documented as such.
