About M32

M32 is the ICD-10-CM diagnosis code for systemic lupus erythematosus (SLE). It belongs to block M30-M36 (systemic connective tissue disorders) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: M32.0 (erythematosus), M32.1 (involvement), M32.8 (erythematosus) and M32.9 (unspecified).

Don't report M32 together with the conditions in its Excludes1 note: lupus erythematosus (discoid) (NOS) (L93.0).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
