Nonrheumatic mitral valve disorder, unspecified

This code signifies a general, unspecified problem with the mitral valve that is not caused by rheumatic fever. It indicates a structural or functional abnormality of the mitral valve, such as regurgitation, stenosis, or prolapse, without a more specific diagnosis being documented.

Use this code when the medical record indicates a mitral valve disorder but lacks further specificity regarding the type of disorder (e.g., stenosis, insufficiency) or its etiology. This is appropriate when the provider has diagnosed a mitral valve issue but has not yet determined or documented the precise nature of the condition.

• Avoid using this code if more specific documentation regarding the mitral valve disorder is available (e.g., I34.0 for mitral valve insufficiency).
• Query the provider for further specificity if the documentation only states "mitral valve disorder" to allow for more precise coding.
• This code should be used as a last resort when no other specific nonrheumatic mitral valve disorder code can be assigned.
