L93 vs M32
L93 (Lupus erythematosus) compared with M32 (Systemic lupus erythematosus (SLE)), 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. L93 carries an Excludes1 note covering M32: “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).
