Systemic lupus erythematosus (SLE) (M32) ICD-10-CM
The M32 code range covers systemic lupus erythematosus (sle) with 12 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the M32 Code Range
The ICD-10 code M32 series is specifically used to classify different forms and complications of systemic lupus erythematosus (SLE), a complex autoimmune disease. These codes cover everything from general SLE diagnoses to detailed organ or system complications and drug-induced lupus conditions.
For example, M32.0 is designated for drug-induced systemic lupus erythematosus, addressing lupus triggered by medications like procainamide or hydralazine. When SLE involves specific organs, such as the heart (M32.11 for endocarditis), lungs (M32.13), kidneys (M32.14 and M32.15 for glomerular and tubulo-interstitial nephropathies), or other systems (M32.19 for various neuropsychiatric or gastrointestinal involvements), distinct codes guide precise medical coding. These include terms such as lupus pneumonitis, lupus glomerulonephritis, and lupus vasculitis. M32.10 covers unspecified organ involvement, while M32.8 and M32.9 capture other forms and unspecified systemic lupus erythematosus, helping clinicians accurately reflect disease complexity in medical records and billing.
