I82.5 vs Z86.718

I82.5 (Chronic embolism and thrombosis of deep veins of lower extremity) compared with Z86.718 (Personal history of other venous thrombosis and embolism), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.

Can these codes be reported together?

No — do not report together. I82.5 carries an Excludes1 note covering Z86.718: “personal history of venous embolism and thrombosis (Z86.718)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
