I80 vs I82.5
I80 (Phlebitis and thrombophlebitis) compared with I82.5 (Chronic embolism and thrombosis of deep veins of lower extremity), 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. I80 carries an Excludes1 note covering I82.5: “venous embolism and thrombosis of lower extremities (I82.4-, I82.5-, I82.81-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
