Family history of other specific disorders (Z83)

ICD-10 code Z83 covers a range of family history diagnoses for specific disorders, helping document hereditary risks in patients. This section includes codes to specify family histories of infectious diseases, blood disorders, diabetes, endocrine and metabolic diseases, eye and ear disorders, respiratory illnesses, and digestive system conditions.

Each subcode under Z83 provides detailed classification for various familial disorders. For example, Z83.0 refers to family history of human immunodeficiency virus (HIV) disease, often noted as maternal HIV infection or family history of AIDS. Codes like Z83.3 capture family history of diabetes mellitus, distinguishing type 1, type 2, and gestational diabetes. Family history of blood and immune disorders, including conditions such as hemophilia and sickle cell anemia, are included under Z83.2. For inherited metabolic issues, subcodes like Z83.42 for familial hypercholesterolemia help coders identify genetic predispositions to high cholesterol. Eye disorders (e.g., glaucoma in Z83.511) and respiratory system diseases are also recorded in this section. These codes guide clinicians and coders by linking commonly known terms; like “family history of tuberculosis” or “FH: Crohn's disease”; directly to the appropriate ICD-10 code for precise family history documentation.

Instructional Notations

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.
