Multiple involvement of mitral and aortic valves

This code signifies the presence of a disease process affecting both the mitral and aortic valves of the heart. This involvement can manifest as stenosis, insufficiency, or a combination of both, impacting the proper function of these critical cardiac structures.

Use this code when documentation clearly indicates a pathological condition simultaneously affecting both the mitral and aortic valves. This is appropriate for conditions like rheumatic heart disease, endocarditis, or degenerative changes impacting both valves concurrently.

• Ensure documentation specifies both mitral and aortic valve involvement; do not use if only one valve is affected.
• This code is for multiple involvement, not just a single, isolated lesion on each valve.
• Always sequence this code after the underlying cause of the valvular disease, if known and documented.
