About M32.1
M32.1 is the ICD-10-CM diagnosis code for systemic lupus erythematosus with organ or system involvement. It belongs to category M32 (systemic lupus erythematosus (SLE)), 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 7 subcodes must be used instead.
Within M32 (systemic lupus erythematosus (SLE)), M32.1 is specifically for systemic lupus erythematosus with organ or system involvement. Related codes cover drug-induced systemic lupus erythematosus (M32.0), other forms of systemic lupus erythematosus (M32.8) and systemic lupus erythematosus, unspecified (M32.9).
To report this condition, pick the subcode that matches the documentation: M32.10 (unspecified), M32.11 (erythematosus), M32.12 (erythematosus), M32.13 (erythematosus), M32.14 (erythematosus), M32.15 (erythematosus) and M32.19 (erythematosus).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
