Acute kidney failure and chronic kidney disease (N17-N19) ICD-10-CM
The N17–N19 section covers acute kidney failure and chronic kidney disease with 18 ICD-10-CM diagnosis codes, of which 15 are billable in fiscal year 2027. The section is organized into the 3 code ranges listed below.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the N17–N19 Code Range
These conditions include acute kidney failure, chronic kidney disease, and kidney failure whose type is unspecified. Chronic kidney disease means kidney function is impaired by lasting kidney damage.
N17 separates acute kidney failure by whether tubular, cortical, or medullary necrosis (tissue death) is named, with other and unspecified options. N18 organizes chronic kidney disease by stage, from stage 1 through stage 5, and includes end stage renal disease and an unspecified option. N19 identifies kidney failure without a specified type.
