I87.31 is the ICD-10-CM diagnosis code for chronic venous hypertension (idiopathic) with ulcer. It belongs to category I87 (other disorders of veins), 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 4 subcodes must be used instead.

Use an additional code to specify site and severity of ulcer (L97.-).
