I82.81Embolism and thrombosis of superficial veins of lower extremities

I82.81 is the ICD-10-CM diagnosis code for embolism and thrombosis of superficial veins of lower extremities. It belongs to category I82 (other venous embolism and thrombosis), 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.

To report this condition, pick the subcode that matches the documentation: I82.811 (extremity), I82.812 (extremity), I82.813 (bilateral) and I82.819 (extremity).
