N19 vs N28.9
N19 (Unspecified kidney failure) compared with N28.9 (Disorder of kidney and ureter, unspecified), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. N19 carries an Excludes1 note covering N28.9: “renal insufficiency (acute) (N28.9)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
