About I87
I87 is the ICD-10-CM diagnosis code for other disorders of veins. It belongs to block I80-I89 (diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: I87.0 (syndrome), I87.1 (vein), I87.2 ((peripheral)), I87.3 ((idiopathic)), I87.8 (veins) and I87.9 (unspecified).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
