Rheumatic mitral valve diseases (I05)
The ICD-10 code I05 covers various rheumatic mitral valve diseases, conditions caused by rheumatic fever that affect the mitral valve in the heart. These codes help classify specific types of valve damage, including stenosis, insufficiency, or combinations of both.
These codes serve to identify disorders such as rheumatic mitral stenosis (I05.0), characterized by narrowing of the mitral valve, sometimes referred to by terms like mitral valve stenosis or pulmonary hypertension due to left-sided valvular heart disease. Rheumatic mitral insufficiency (I05.1) refers to valve leakage, also known as rheumatic mitral regurgitation. When stenosis and insufficiency occur together, I05.2 is used, encompassing conditions like mitral stenosis with regurgitation. Additional forms of rheumatic damage to the mitral valve, such as leaflet changes and annular calcification, fall under I05.8. For unspecified rheumatic mitral valve diseases or chronic rheumatic carditis affecting the valve, I05.9 applies. Using these codes accurately supports proper documentation and management of rheumatic heart complications.
Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- mitral valve disease specified as nonrheumatic I34
- mitral valve disease with aortic and/or tricuspid valve involvement I08
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Mitral Valve Stenosis
Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
