L95 vs M54.0
L95 (Vasculitis limited to skin, not elsewhere classified) compared with M54.0 (Panniculitis affecting regions of neck and back), 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. L95 carries an Excludes1 note covering M54.0: “panniculitis of neck and back (M54.0-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
