I87.02Postthrombotic syndrome with inflammation

I87.02 is the ICD-10-CM diagnosis code for Postthrombotic syndrome with inflammation. It belongs to category I87 (other disorders of veins), 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 I87.0 (Postthrombotic syndrome), I87.02 is specifically for Postthrombotic syndrome with inflammation. Related codes cover without complications (I87.00), with ulcer (I87.01), with ulcer and inflammation (I87.03) and with other complications (I87.09).

To report this condition, pick the subcode that matches the documentation: I87.021 (of right lower extremity), I87.022 (of left lower extremity), I87.023 (of bilateral lower extremity) and I87.029 (of unspecified lower extremity).

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