ICD-10 Code F01.C0 – Vascular Dementia, Severe, Without Behavioral Disturbance, Psychotic Disturbance, Mood Disturbance, and Anxiety (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.C0 – Vascular dementia, severe, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety
What it is
This code identifies severe vascular dementia caused by cerebrovascular disease, with no documented behavioral, psychotic, mood, or anxiety disturbance. Use it when the record clearly states severe dementia and excludes those associated symptoms.
Clinical signs
Clinical features vary; refer to documentation. Severe vascular dementia commonly includes major cognitive impairment, poor judgment, and dependence in daily activities, with evidence linking the dementia to vascular injury.
When to use this code
Use F01.C0 when the provider documents severe vascular dementia and specifically notes the absence of behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. It also fits when severity is stated as severe and the chart supports a vascular cause. Check documentation if symptom qualifiers are unclear.
Do not use for
Do not use this code if the record documents behavioral, psychotic, mood, or anxiety disturbance with the dementia. Also avoid it when vascular dementia is not specified as severe or when the diagnosis is uncertain.
Coding tip
Verify both severity and the absence of qualifying disturbances before assigning F01.C0.
