About I83.0
I83.0 is the ICD-10-CM diagnosis code for varicose veins of lower extremities with ulcer. It belongs to category I83 (varicose veins of lower extremities), 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 3 subcodes must be used instead.
Within I83 (varicose veins of lower extremities), I83.0 is specifically for varicose veins of lower extremities with ulcer. Related codes cover with inflammation (I83.1), with both ulcer and inflammation (I83.2), with other complications (I83.8) and Asymptomatic varicose veins of lower extremities (I83.9).
To report this condition, pick the subcode that matches the documentation: I83.00 (ulcer), I83.01 (ulcer) and I83.02 (ulcer).
