M32 vs M62

M32 (Systemic lupus erythematosus (SLE)) compared with M62 (Other disorders of muscle), 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. M62 carries an Excludes1 note covering M32: “myopathy in systemic lupus erythematosus (M32.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
