In simple words: This code indicates a problem with the aortic valve in your heart caused by rheumatic heart disease. It's used when the problem isn't simply a narrowed valve, a leaky valve, or both.

Other rheumatic aortic valve diseases. This code specifies that the aortic valve is affected by rheumatic heart disease, but doesn't fit the descriptions of stenosis, insufficiency, or combined stenosis and insufficiency.

Example 1: A patient with a history of rheumatic fever presents with symptoms of shortness of breath and fatigue. Echocardiography reveals thickening and scarring of the aortic valve, but without significant stenosis or insufficiency. The diagnosis of other rheumatic aortic valve disease is made, and code I06.8 is assigned., A patient with long-standing rheumatic heart disease is found to have mild aortic regurgitation on physical exam. However, imaging studies suggest that the primary valve abnormality is not regurgitation, but rather a combination of fibrosis and calcification. In this scenario, I06.8 would be appropriate., A patient is admitted for management of heart failure. The patient has a known history of rheumatic heart disease, with documentation of both mitral stenosis and aortic valve involvement. If the aortic valve issue is not clearly stenosis or regurgitation, I06.8 might be used in addition to the code for mitral stenosis.

Documentation should clearly state the specific type of rheumatic aortic valve disease present, as well as any associated symptoms or clinical findings. Echocardiography or other imaging results should be included to support the diagnosis. The documentation must also exclude the presence of aortic stenosis (I06.0), aortic insufficiency (I06.1), and combined stenosis and insufficiency (I06.2).

** If the patient has rheumatic involvement of multiple heart valves, including the aortic valve, use codes I08.- (Multiple valve diseases) instead of I06.8. Be sure to specify the type of dysfunction for the other affected valves.
