Z81.4: Family history of other substance abuse

Family history of other substance abuse, denoted by the ICD-10 code Z81.4, is a medical descriptor used to classify individuals who have a significant history of substance abuse in their family. Substance abuse refers to the harmful or hazardous use of psychoactive substances, which can lead to addiction. These could include, but are not limited to, illicit drugs, alcohol, prescription medications, and other substances used outside their medical or social conventions. Having a family history means that one or more relatives, such as parents or grandparents, have had an addiction to these substances. This genetic predisposition can increase the individual’s vulnerability to developing similar addiction problems, though it doesn't guarantee the occurrence. Signs of substance abuse might be behavioral changes, physical signs, withdrawal symptoms, and neglecting responsibilities.
