V18.4
ICD-9-CMThis code indicates a documented family history of intellectual disabilities, also known as developmental disabilities or mental retardation. It signifies that a patient has a blood relative (e.g., parent, sibling, grandparent) who has been diagnosed with an intellectual disability. This is a risk factor, not a current condition of the patient.
Use this code when a patient's medical record explicitly states a family history of intellectual disabilities. This is often identified during initial patient intake, family history questionnaires, or genetic counseling. It's relevant for assessing potential genetic predispositions or for counseling purposes.
