Nonrheumatic mitral (valve) insufficiency
ICD-10 I34.0 is a billable code used to indicate a diagnosis of nonrheumatic mitral (valve) insufficiency.
Nonrheumatic mitral valve insufficiency is a condition characterized by the inability of the mitral valve to close properly, leading to the backflow of blood from the left ventricle into the left atrium during systole. This condition can result from various etiologies, including degenerative changes, ischemic heart disease, or congenital defects. Clinically, patients may present with symptoms such as dyspnea, fatigue, palpitations, and signs of heart failure. The anatomy involved includes the mitral valve, which consists of two leaflets, chordae tendineae, and papillary muscles that maintain valve function. Disease progression can lead to left atrial enlargement, pulmonary hypertension, and ultimately heart failure if left untreated. Diagnostic considerations include echocardiography, which is the primary imaging modality used to assess mitral valve structure and function, along with Doppler studies to evaluate the severity of regurgitation. Other diagnostic tools may include chest X-rays and cardiac MRI in complex cases.

I34.0 covers nonrheumatic mitral valve insufficiency, which may arise from degenerative changes, ischemic heart disease, or congenital anomalies. It does not include rheumatic causes or other valvular insufficiencies.
I34.0 should be used when the mitral valve insufficiency is confirmed to be nonrheumatic in nature, differentiating it from I34.1, which is specifically for rheumatic causes.
Documentation should include a detailed clinical history, physical examination findings, echocardiographic reports demonstrating mitral valve insufficiency, and any relevant lab results that support the diagnosis.
