Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

pulmonary valve disorder specified as congenital (Q22.1, Q22.2, Q22.3)
pulmonary valve disorder specified as rheumatic (I09.89)
