I15.1 — Hypertension secondary to other renal disorders
I15.1 is a billable, specific ICD-10-CM code for hypertension secondary to other renal disorders. It is valid for submission on a claim.
Other codes that can never be billed with I15.1
These codes carry an Excludes1 note pointing at I15.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I15.1 alone.
- I12Hypertensive chronic kidney disease
Risk adjustment
I15.1 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
I15.1 is named in 19 Medicare coverage policies — 19 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
