About I83.1
I83.1 is the ICD-10-CM diagnosis code for varicose veins of lower extremities with 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 3 subcodes must be used instead.

Related codes cover with ulcer (I83.0), 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: I83.10 (inflammation), I83.11 (inflammation) and I83.12 (inflammation).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
