Systemic disorders of connective tissue in diseases classified elsewhere (M36) ICD-10-CM
The M36 code range covers systemic disorders of connective tissue in diseases classified elsewhere with 7 ICD-10-CM diagnosis codes. 6 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the M36 Code Range
These conditions affect connective tissue throughout the body and occur in diseases classified elsewhere.
The subdivisions separate conditions by the associated disease and, in some cases, the type of joint disorder. M36.0 identifies dermato(poly)myositis, a muscle disorder, in neoplastic disease. M36.1 identifies joint disorders in neoplastic disease. M36.2 identifies joint disorders in hemophilia, while M36.3 identifies them in other blood disorders. M36.4 covers joint disorders in hypersensitivity reactions classified elsewhere. M36.8 covers systemic connective tissue disorders in other diseases classified elsewhere.
