I70.1Atherosclerosis of renal artery

Billable / specific codeICD-10-CM

I70.1 is a billable, specific ICD-10-CM code for atherosclerosis of renal artery. It is valid for submission on a claim.

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.

  • atherosclerosis of renal arterioles (I12.-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Goldblatt's kidney

Other codes that can never be billed with I70.1

These codes carry an Excludes1 note pointing at I70.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I70.1 alone.

  • N28.0Ischemia and infarction of kidney

Risk adjustment

I70.1 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.

Medicare coverage

I70.1 is named in 29 Medicare coverage policies 29 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
