About I83
I83 is the ICD-10-CM diagnosis code for varicose veins of lower extremities. 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 5 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: I83.0 (with ulcer), I83.1 (with inflammation), I83.2 (with both ulcer and inflammation), I83.8 (with other complications) and I83.9 (extremities).
The conditions in its Excludes2 note aren't part of I83, but may be coded alongside it if the patient has both: varicose veins complicating pregnancy (O22.0-) and varicose veins complicating the puerperium (O87.4).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
