Rheumatic disorders of both mitral and aortic valves

This code signifies the presence of rheumatic disease affecting both the mitral and aortic heart valves. This condition involves inflammation and damage to these valves, typically as a sequela of acute rheumatic fever, leading to valvular dysfunction such as stenosis or regurgitation.

Apply this code when documentation explicitly states a diagnosis of rheumatic involvement of both the mitral and aortic valves. This is appropriate for chronic conditions where the rheumatic etiology is confirmed or strongly suspected as the cause of the combined valvular disease.

• Ensure documentation specifies rheumatic etiology for both valves; otherwise, use non-rheumatic valvular disease codes.
• Do not use this code for isolated mitral or aortic rheumatic valve disease; separate codes exist for those conditions.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity impacting care.
