Adult osteomalacia (M83) ICD-10-CM
The M83 code range covers adult osteomalacia with 9 ICD-10-CM diagnosis codes. 8 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 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 M83 Code Range
Adult osteomalacia is a bone disorder in the broader group of disorders of bone density and structure.
The subdivisions distinguish puerperal M83.0 and senile M83.1 osteomalacia. They also separate cases due to malabsorption M83.2 or malnutrition M83.3. Aluminum bone disease M83.4 and other drug-induced osteomalacia M83.5 have separate subdivisions, as do other M83.8 and unspecified M83.9 adult osteomalacia.
