I83.20Varicose veins of unspecified lower extremity with both ulcer and inflammation

I83.20 is the ICD-10-CM diagnosis code for varicose veins of unspecified lower extremity with both ulcer and inflammation. 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 7 subcodes must be used instead.

Within I83.2, choose I83.20 (unspecified lower extremity with both ulcer and inflammation) only when documentation doesn't support a more specific option: right lower extremity with both ulcer and inflammation (I83.21) and left lower extremity with both ulcer and inflammation (I83.22).

To report this condition, pick the subcode that matches the documentation: I83.201 (inflammation), I83.202 (inflammation), I83.203 (inflammation), I83.204 (inflammation), I83.205 (inflammation), I83.208 (inflammation) and I83.209 (inflammation).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
