Other nonrheumatic mitral valve disorders

This code represents various non-rheumatic conditions affecting the mitral valve that are not specifically classified elsewhere. These disorders involve structural or functional abnormalities of the mitral valve apparatus, excluding those caused by rheumatic fever. This can include congenital anomalies, degenerative changes, or other acquired conditions impacting valve function.

Use this code when documentation specifies a non-rheumatic mitral valve disorder that doesn't have a more specific ICD-10-CM code. Examples include mitral valve prolapse with regurgitation not specified as myxomatous, or other congenital mitral valve anomalies not otherwise categorized. Documentation should clearly state the non-rheumatic etiology and the specific mitral valve abnormality.

• Always seek a more specific code if available (e.g., I34.0 for nonrheumatic mitral valve insufficiency).
• Ensure documentation explicitly rules out a rheumatic origin for the mitral valve disorder.
• Do not use this code for conditions like mitral stenosis or insufficiency if a more precise code exists.
