ICD-10 Code F01.A2 – Vascular dementia, mild, with psychotic disturbance (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.A2 – Vascular dementia, mild, with psychotic disturbance
What it is
This code identifies mild vascular dementia caused by cerebrovascular disease, with a documented psychotic disturbance. Use it when the record shows dementia symptoms plus hallucinations, delusions, or similar psychotic features.
Clinical signs
Typical findings include mild cognitive decline affecting memory, judgment, or executive function, along with psychotic symptoms. Clinical features vary; refer to documentation for the specific disturbance and severity.
When to use this code
Use F01.A2 when the provider clearly documents vascular dementia, rates it as mild, and also notes psychotic disturbance. The chart should support both the dementia diagnosis and the psychotic feature. If severity or psychosis is not stated, check documentation before coding.
Do not use for
Do not use this code for Alzheimer’s dementia, unspecified dementia, or vascular dementia without psychotic disturbance. Also avoid it when the record does not confirm mild severity or the psychotic feature.
Coding tip
Confirm that both the dementia type and the psychotic disturbance are documented together before assigning F01.A2.
