Family history of other specific disorders (Z83) ICD-10-CM
The Z83 code range covers family history of other specific disorders with 26 ICD-10-CM diagnosis codes. 19 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 Z83 Code Range
These codes describe family histories of specific diseases and disorders. They identify the type of condition in the family.
The subdivisions separate HIV disease and other infectious or parasitic diseases, blood and immune disorders, diabetes, other endocrine or metabolic diseases, eye and ear disorders, respiratory diseases, and digestive diseases. Some groups narrow further: Z83.4 includes family histories of specific endocrine and lipid disorders, while Z83.5 separates eye disorders from ear disorders. Within digestive diseases, Z83.71 distinguishes types of colon polyps, and Z83.72 identifies familial adenomatous polyposis.
