N08 vs N16
N08 (Glomerular disorders in diseases classified elsewhere) compared with N16 (Renal tubulo-interstitial disorders in diseases classified elsewhere), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.

No — do not report together. N08 carries an Excludes1 note covering N16: “pyelonephritis in diseases classified elsewhere (N16)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
