I12 — Hypertensive chronic kidney disease
I12 is a non-billable header ICD-10-CM code for hypertensive chronic kidney disease. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
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.
- acute kidney failure (N17.-)
Includes
Conditions this code covers.
Other codes that can never be billed with I12
These codes carry an Excludes1 note pointing at I12. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I12 alone.
- N26Unspecified contracted kidney
Risk adjustment
I12 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 I12
2 child codes. Green means billable.
