ICD-10 for Mitral Valve Regurgitation: A Comprehensive Guide (2025 Edition)

Introduction

Mitral valve regurgitation (MR), also known as mitral insufficiency, is a condition in which the mitral valve does not close properly, allowing blood to leak back into the left atrium during systole. This can lead to a variety of symptoms, including shortness of breath, fatigue, and chest pain. In severe cases, MR can lead to heart failure.

The International Classification of Diseases, 10th Revision (ICD-10) is a system of codes used to classify diseases and health conditions. ICD-10 codes are used for a variety of purposes, including billing, research, and quality improvement.

The following ICD-10 codes are used to classify MR:

• I05.0: Acute rheumatic mitral valve regurgitation
• I05.1: Subacute rheumatic mitral valve regurgitation
• I05.2: Chronic rheumatic mitral valve regurgitation
• I05.8: Other rheumatic mitral valve regurgitation
• I05.9: Mitral valve regurgitation, unspecified
• I34.0: Mitral valve regurgitation with stenosis
• I34.1: Mitral valve regurgitation with prolapse
• I34.2: Mitral valve regurgitation with other specified mitral valve disorders
• I34.8: Mitral valve regurgitation with other specified heart disorders
• I34.9: Mitral valve regurgitation, unspecified

Epidemiology

MR is a common condition, affecting approximately 2% of the population. It is more common in women than in men, and the risk of developing MR increases with age.

Etiology

MR can be caused by a variety of factors, including:

• Rheumatic fever
• Endocarditis
• Ischemic heart disease
• Mitral valve prolapse
• Hypertrophic cardiomyopathy
• Dilated cardiomyopathy
• Congenital heart defects

Symptoms

The symptoms of MR can vary depending on the severity of the condition. Mild MR may not cause any symptoms, while severe MR can lead to a variety of symptoms, including:

• Shortness of breath
• Fatigue
• Chest pain
• Palpitations
• Lightheadedness
• Dizziness
• Syncope

Diagnosis

MR is diagnosed based on a physical examination and echocardiography. Echocardiography is an ultrasound test that can visualize the heart and its valves. Echocardiography can be used to assess the severity of MR and to identify the underlying cause.

Treatment

The treatment for MR depends on the severity of the condition. Mild MR may not require treatment, while severe MR may require surgery.

Medical treatment for MR may include:

• Diuretics to reduce fluid retention
• ACE inhibitors or angiotensin receptor blockers to lower blood pressure
• Beta-blockers to slow the heart rate

Surgery for MR may be necessary if the condition is severe and causing symptoms. The type of surgery performed will depend on the underlying cause of the MR.

Prognosis

The prognosis for MR depends on the severity of the condition and the underlying cause. Mild MR typically has a good prognosis, while severe MR can lead to heart failure and death.

Prevention

There is no sure way to prevent MR, but there are some things you can do to reduce your risk, such as:

• Getting vaccinated against rheumatic fever
• Practicing good oral hygiene to prevent endocarditis
• Managing your blood pressure and cholesterol levels
• Exercising regularly
• Maintaining a healthy weight

Conclusion

MR is a common condition that can cause a variety of symptoms, including shortness of breath, fatigue, and chest pain. The diagnosis and treatment of MR depends on the severity of the condition and the underlying cause. With proper treatment, most people with MR can live long, healthy lives.
