I70.2 vs I73.9
I70.2 (Atherosclerosis of native arteries of the extremities) compared with I73.9 (Peripheral vascular disease, unspecified), 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. I73.9 carries an Excludes1 note covering I70.2: “atherosclerosis of the extremities (I70.2--I70.7-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
