Nonrheumatic mitral (valve) stenosis
ICD-10 I34.2 is a billable code used to indicate a diagnosis of nonrheumatic mitral (valve) stenosis.
Nonrheumatic mitral stenosis is a condition characterized by the narrowing of the mitral valve, which impedes blood flow from the left atrium to the left ventricle. This condition can result from various factors, including degenerative changes, calcification, or congenital anomalies. Clinically, patients may present with symptoms such as dyspnea, fatigue, palpitations, and signs of heart failure due to increased left atrial pressure. The anatomy involved includes the mitral valve leaflets, chordae tendineae, and surrounding structures. Over time, untreated mitral stenosis can lead to significant complications, including atrial fibrillation, pulmonary hypertension, and heart failure. Diagnosis typically involves echocardiography, which assesses valve morphology and hemodynamics, and may be supplemented by cardiac catheterization in complex cases. Understanding the progression of the disease is crucial for timely intervention, which may include medical management or surgical options such as balloon valvuloplasty or valve replacement.

I34.2 specifically covers nonrheumatic mitral stenosis, which can arise from degenerative changes, calcification, or congenital defects, but does not include rheumatic causes.
I34.2 should be used when the mitral stenosis is confirmed to be nonrheumatic in origin, differentiating it from I34.1, which is used for rheumatic causes.
Documentation should include clinical findings, echocardiographic results indicating mitral stenosis, and any relevant history that rules out rheumatic disease.
