    ICD-10-CM Code For Personality And Behavioral Disorders Due To Known Physiological Condition: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group F07 includes personality and behavioral disorders that result from an identifiable physiological condition affecting brain function, such as traumatic brain injury, neurodegenerative disease, or metabolic encephalopathy. These ICD-10-CM diagnosis codes are used to document behavioral disturbances secondary to medical or neurological disorders, capturing disease etiology and clinical complexity relevant to neuropsychiatric care. Accurate coding within the ICD-10-CM F07 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM F07: Personality And Behavioral Disorders Due To Known Physiological Condition Overview

    The ICD-10-CM F07 group captures personality and behavioral changes that are directly attributable to an identifiable physiological condition affecting the brain or nervous system. These diagnoses target neuropsychiatric manifestations secondary to traumatic brain injury, neurodegenerative disease, metabolic or structural brain disorders, and other medical conditions. Accurate coding matters for appropriate clinical documentation and reimbursement because it links behavioral symptoms to an underlying medical cause and supports medical necessity for services.

    When to Use

    Use a code from this group when behavioral or personality changes are documented as resulting from a specific physiological condition rather than a primary psychiatric disorder. Select the code that reflects the documented clinical presentation and the underlying medical etiology when available.

    Typical Clinical Scenarios

    • An older adult with a recent ischemic stroke develops new-onset disinhibition, impulsivity, and personality change noted by family over weeks; the patient is brought to neurology and behavioral medicine for evaluation after safety concerns at home. A diagnosis from this group is assigned because the personality and behavioral changes are clearly attributed to a recent identifiable physiological brain lesion affecting frontal networks. Typical codes: F07.0, F07.81
    • A middle-aged patient with long-standing HIV infection and progressive cognitive decline presents to an outpatient clinic with marked apathy, social withdrawal, and alteration in customary behavior over months; neuroimaging and infectious disease workup show cortical involvement related to the known medical condition. Because the behavioral syndrome is judged secondary to the established physiological illness rather than a primary psychiatric disorder, a code from this group is used to capture the disorder. Typical codes: F07.89, F07.9
    • A hospitalized patient in the medical ward with severe traumatic brain injury is observed to have acute personality changes including aggression, mood lability, and impaired judgment that complicate rehabilitation and discharge planning. The diagnostic assignment from this group documents the behavioral disturbance as a consequence of the identifiable neurologic injury and guides communication with rehabilitation and care coordination teams. Typical codes: F07.0, F07.81
