ICD-10 Code F01.B2 – Vascular dementia, moderate, with psychotic disturbance (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.B2 – Vascular dementia, moderate, with psychotic disturbance
What it is
Use this code for vascular dementia of moderate severity when psychotic symptoms are documented. It identifies cognitive decline caused by cerebrovascular disease, with hallucinations, delusions, or other psychotic disturbance noted in the record.
Clinical signs
Clinical features typically include impaired memory, slowed thinking, and reduced ability to manage daily activities at a moderate level. Psychotic disturbance may be present; clinical features vary, so refer to documentation.
When to use this code
Assign F01.B2 when the provider documents vascular dementia, confirms moderate severity, and also states psychotic disturbance. Use it for encounter notes that clearly link the dementia diagnosis to cerebrovascular disease and describe psychotic features. If severity or psychosis is not documented, check documentation.
Do not use for
Do not use this code for vascular dementia without psychotic disturbance, or when severity is not moderate. It is also incorrect for other dementia types unless the record specifically supports vascular dementia.
Coding tip
Verify both the dementia severity and the psychotic disturbance in the provider note before coding.
