coding echos-rheumatic vs non-rheumatic

I just wanted to clarify when I am coding an echo (transthoracic echocardiogram) The providers are interpreting what they found in the valves. When a pt has both mitral valve and tricuspsid valve disorder (multiple valve diseases) we code a combo code I08.1-Rheumatic disorders of both mitral valve,and tricuspid valves. Per the guidance this automatically becomes rheumatic whether the provider documents this in the note or not.

My question is what if a pt pt only has tricupsid...
