Systemic lupus erythematosus (SLE) (M32) ICD-10-CM

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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the M32 range.
Drug Induced Lupus Erythematosus
An autoimmune disorder, similar to systemic lupus erythematosus, that is caused by certain drugs.
Lupus Erythematosus, Systemic
A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.
About the M32 Code Range
Systemic lupus erythematosus, or SLE, is a recurring inflammatory disorder of connective tissue. It often affects the skin, joints, and kidneys.
M32 separates drug-induced lupus from lupus with organ or system involvement, other forms, and unspecified lupus. Within M32.1, codes distinguish heart, lung, and kidney involvement. They also distinguish unspecified organ or system involvement from other organ or system involvement.
