Wiki Mitral Stenosis with insufficiency

Question to all my fellow coders out there:

When the documentation states that patient has both conditions do you code them separately or use the combo code of I05.0? When you use the old I-9 Code and convert it to the I-10 you get the I05.0. However it does say rheumatic in the actual code definition. Yet all my research says that it doesn't matter if it is actually rheumatic in nature. You would still use the I05.1 When using the index it too takes you to the I05.0 code. This still leads me to question when the nonrheumatic code of I34.2 is used. Going on my assumption it would be used when no insufficiency is noted. Can anyone shed light on this for me? Or confirm that I am indeed correct in my assumption? Thanks:cool:
