M90 vs N25.0
M90 (Osteopathies in diseases classified elsewhere) compared with N25.0 (Renal osteodystrophy), 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. M90 carries an Excludes1 note covering N25.0: “renal osteodystrophy (N25.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
