I12Hypertensive chronic kidney disease

I12 is the ICD-10-CM diagnosis code for hypertensive chronic kidney disease. It belongs to block I10-I1A (hypertensive diseases) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: I12.0 (with stage 5 chronic kidney disease or end stage renal disease) and I12.9 (with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease).

Don't report I12 together with the conditions in its Excludes1 note: hypertension due to kidney disease (I15.0, I15.1), renovascular hypertension (I15.0) and secondary hypertension (I15.-).

The conditions in its Excludes2 note aren't part of I12, but may be coded alongside it if the patient has both: acute kidney failure (N17.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
