About I07
I07 is the ICD-10-CM diagnosis code for rheumatic tricuspid valve diseases. It belongs to block I05-I09 (chronic rheumatic heart diseases) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: I07.0 (stenosis), I07.1 (insufficiency), I07.2 (insufficiency), I07.8 (diseases) and I07.9 (unspecified).
Don't report I07 together with the conditions in its Excludes1 note: tricuspid valve disease specified as nonrheumatic (I36.-) and tricuspid valve disease with aortic and/or mitral valve involvement (I08.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
