G54 vs M54.1
G54 (Nerve root and plexus disorders) compared with M54.1 (Radiculopathy), 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. G54 carries an Excludes1 note covering M54.1: “radiculitis NOS (M54.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
