I70.2 — Atherosclerosis of native arteries of the extremities
I70.2 is a non-billable header ICD-10-CM code for atherosclerosis of native arteries of the extremities. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Use additional code
Add a secondary code to capture the detail described below.
- code, if applicable, to identify chronic total occlusion of artery of extremity (I70.92)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Mönckeberg's (medial) sclerosis
Other codes that can never be billed with I70.2
These codes carry an Excludes1 note pointing at I70.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I70.2 alone.
Risk adjustment
I70.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead I70.2
8 child codes. Green means billable.
