International Classification of Diseases

Last updated: 3/24/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates that the mitral valve in your heart is not closing completely, allowing blood to leak backward from the left ventricle into the left atrium. This condition is specifically not caused by rheumatic fever or rheumatic heart disease. The mitral valve insufficiency (also called mitral regurgitation) can be caused by various factors such as age-related wear, heart muscle problems, or other conditions affecting the valve structure.

Additional Information

Severity can range from mild to severe. Treatment depends on the degree of valve insufficiency and symptoms. Some patients may need no treatment while others may require medications or surgical intervention.
