Mitral and aortic valve diseases, unspecified

This code signifies the presence of co-occurring mitral and aortic valve disorders where the specific nature or etiology of these valvular diseases is not documented. It indicates a general diagnosis of combined dysfunction affecting both the mitral and aortic heart valves without further detail.

This code is appropriate when documentation indicates simultaneous involvement of both the mitral and aortic valves, but lacks specificity regarding the type (e.g., stenosis, insufficiency), severity, or cause of the valvular disease. It is used when the physician's diagnosis is simply "mitral and aortic valve disease" without further elaboration.

• Avoid using this code if more specific ICD-9-CM codes for mitral or aortic valve diseases (e.g., stenosis, insufficiency) can be assigned based on documentation.
• Review the medical record carefully for any clues that might lead to a more precise diagnosis, such as echocardiogram reports or physician notes detailing the specific valve pathology.
• This code represents an unspecified diagnosis; query the provider for greater specificity if possible to improve coding accuracy and data quality.
