I80.22Phlebitis and thrombophlebitis of popliteal vein

I80.22 is the ICD-10-CM diagnosis code for phlebitis and thrombophlebitis of popliteal vein. It belongs to category I80 (phlebitis and thrombophlebitis), 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.

Within I80.2 (phlebitis and thrombophlebitis of other and unspecified deep vessels of lower extremities), I80.22 is specifically for phlebitis and thrombophlebitis of popliteal vein. Related codes cover unspecified deep vessels of lower extremities (I80.20), iliac vein (I80.21), tibial vein (I80.23), peroneal vein (I80.24), calf muscular vein (I80.25) and other deep vessels of lower extremities (I80.29).

To report this condition, pick the subcode that matches the documentation: I80.221 (vein), I80.222 (vein), I80.223 (bilateral) and I80.229 (vein).
