Family history of other mental and behavioral disorders

This code indicates a documented family history of mental or behavioral health conditions that are not specifically categorized elsewhere. It signifies a genetic predisposition or familial pattern of psychiatric illness, excluding conditions like mood disorders, schizophrenia, or substance abuse, which have their own specific family history codes.

Apply this code when a patient's family history includes conditions such as anxiety disorders (excluding mood disorders), personality disorders, eating disorders, or neurodevelopmental disorders (e.g., ADHD, autism spectrum disorder) that are not covered by more specific Z codes. This is often relevant for risk assessment, screening, or when considering differential diagnoses.

• Always ensure the specific mental or behavioral disorder is not covered by a more precise family history code (e.g., Z81.0 for schizophrenia, Z81.3 for mood disorders).
• Documentation must clearly state "family history of" the relevant mental/behavioral disorder.
• This code is for family history only; do not use it for a patient's personal diagnosis.
