Z83: Family history of other specific disorders
Z83.0: Family history of human immunodeficiency virus [HIV] disease
The term "Family history of human immunodeficiency virus [HIV] disease" refers to a specific medical history in which a person has immediate family members (such as parents, siblings, or children) who have been diagnosed with HIV. HIV is a virus that weakens the immune system by attacking crucial defensive cells called CD4 cells. Over time, as the immune system becomes severely compromised, disease progression can lead to acquired immunodeficiency syndrome (AIDS), the most advanced stage of HIV infection. Having a family history of HIV does not necessarily mean an individual will contract the virus, as HIV is not inherited genetically but primarily transmitted through unprotected sexual intercourse, sharing of contaminated needles, or mother-to-child during birth or breastfeeding. Nonetheless, a family history can have psychological implications and may influence a person's behavior or decisions pertaining to potential risk factors.
