About I13

I13 is the ICD-10-CM diagnosis code for hypertensive heart and 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 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: I13.0 (with heart failure and stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease), I13.1 (without heart failure) and I13.2 (with heart failure and with stage 5 chronic kidney disease, or end stage renal disease).

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