Rheumatic aortic valve disease, unspecified

This code signifies a form of heart valve disease affecting the aortic valve, specifically caused by rheumatic fever, where the precise nature or severity of the valve involvement (e.g., stenosis, insufficiency) is not documented. It indicates a history of rheumatic fever has damaged the aortic valve, but the specific functional impairment is unknown or unstated.

Use this code when documentation confirms rheumatic etiology of aortic valve disease but lacks further specificity regarding the type (e.g., stenosis, regurgitation) or extent of the valve dysfunction. This is appropriate when the physician notes "rheumatic aortic valve disease, unspecified" or similar language without additional details.

• Avoid using this code if the documentation specifies aortic stenosis, insufficiency, or both due to rheumatic fever; instead, use the more specific codes.
• Ensure the medical record clearly links the aortic valve disease to a rheumatic origin.
• Query the provider for greater specificity if the documentation only states "rheumatic heart disease" without mentioning valve involvement or if the aortic valve involvement is specified but the rheumatic etiology is unclear.
