2025 ICD-10-CM code I34.2
(Active) Effective Date: N/A Revision Date: N/A Cardiovascular - Other forms of heart disease Diseases of the circulatory system Feed
Nonrheumatic mitral valve stenosis is a narrowing of the mitral valve that is not caused by rheumatic fever.
Modifiers may be applicable depending on the circumstances of the service provided (e.g., location, anesthesia, or other add-on codes).
Medical necessity for treatment of nonrheumatic mitral stenosis is established based on the presence of symptoms (dyspnea, fatigue, edema), the severity of the stenosis as determined by echocardiography, and the potential for complications (e.g., heart failure, pulmonary hypertension).
The clinical responsibility for managing a patient with I34.2 involves a comprehensive assessment of the severity of the stenosis, symptom management, and determination of the most appropriate treatment strategy. This may include medication to manage symptoms and the potential need for surgical intervention or other procedures, as determined by the cardiologist and/or cardiac surgeon.
In simple words: This code describes a problem with the mitral valve in your heart. The mitral valve is like a door between two chambers of your heart.In mitral stenosis, this "door" doesn't open all the way, making it harder for blood to flow through. This isn't caused by rheumatic fever.You might feel tired, short of breath, or have a fast heartbeat.
Nonrheumatic mitral valve stenosis (I34.2) refers to a narrowing of the mitral valve opening, hindering the blood flow from the left atrium to the left ventricle. This condition is not caused by rheumatic heart disease. The stenosis can result from various factors, including calcification of the valve leaflets, congenital abnormalities, or other degenerative processes.Symptoms may include shortness of breath, fatigue, palpitations, and edema. Diagnosis involves physical examination, echocardiography, and other cardiac investigations. Treatment options range from medical management to surgical intervention, depending on the severity of the stenosis and the patient's overall condition.
Example 1: A 60-year-old female presents with progressive shortness of breath and fatigue. Echocardiography reveals moderate nonrheumatic mitral stenosis with calcification of the valve leaflets.The patient is started on diuretics to manage fluid overload and referred for cardiac catheterization to assess the severity of the stenosis further before considering valve repair or replacement., A 45-year-old male with a history of congenital heart disease is diagnosed with mild nonrheumatic mitral stenosis during a routine check-up.The patient is asymptomatic and managed conservatively with regular echocardiographic monitoring., A 72-year-old female experiences acute pulmonary edema due to severe nonrheumatic mitral stenosis.She undergoes urgent mitral valve replacement surgery.
** This code is used for the diagnosis of nonrheumatic mitral valve stenosis. It's crucial to differentiate it from rheumatic mitral stenosis (I05.0) and other mitral valve disorders (I34.0, I34.1, I34.8, I34.9). The severity of the stenosis impacts treatment decisions and should be clearly documented.
