    ICD-10-CM Code For Dementia In Other Diseases Classified Elsewhere: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group F02 includes dementia syndromes that occur as a direct result of other identified medical conditions, such as vascular disease, Parkinson disease, or other systemic and neurological disorders. These ICD-10-CM diagnosis codes are used to document cognitive impairment caused by another diagnosed condition, capturing disease severity, associated organ or system involvement, and clinical complexity relevant to management. Accurate coding within the ICD-10-CM F02 group supports appropriate reimbursement, complete clinical documentation, and proper claim adjudication.

    ICD-10-CM F02: Dementia In Other Diseases Classified Elsewhere Overview

    The codes in this group represent dementia syndromes that arise as direct consequences of other underlying medical conditions rather than primary neurodegenerative disorders. They target cognitive decline affecting memory, thinking, and behavior due to identifiable physiological causes affecting the nervous system or systemic disease. Accurate coding matters for reimbursement because it links dementia to the causative condition and supports appropriate claim adjudication and resource allocation.

    When to Use

    Use a code from this group when clinical documentation attributes dementia signs and symptoms to a specific underlying disease rather than primary dementing disorders. Select the code that specifies the causative condition and the presence of dementia to reflect clinical complexity and support claims processing.

    Typical Clinical Scenarios

    • An 82-year-old nursing home resident with long-standing Parkinson disease develops progressive memory loss, visuospatial impairment, and fluctuating attention over months; caregivers report increasing falls and daytime hallucinations prompting evaluation for cognitive decline related to the neurologic disorder. A coder assigns a dementia due to another neurologic disease classified elsewhere when the cognitive deficits are attributable to Parkinson disease and are documented as dementia. Typical codes: F02.81, F02.818
    • A 68-year-old man with documented stroke six months prior presents to neurology with new global cognitive impairment, executive dysfunction, and slowed processing that interferes with independent living, leading to initiation of home health services. Because the cognitive disorder is a direct consequence of cerebrovascular disease and is persistent, the dementia due to another disease classification is used to capture the post-stroke dementia. Typical codes: F02.80, F02.81
    • A 60-year-old woman with longstanding HIV infection and progressive decline in memory, attention, and behavior over several months is hospitalized for acute confusion and inability to perform activities of daily living; workup attributes the cognitive syndrome to HIV-associated neurocognitive disorder evolving into dementia. In this setting a dementia code linked to the underlying systemic disease is assigned to reflect dementia secondary to the known physiologic condition. Typical codes: F02.A0, F02.A11
