ICD-10 Code F01.C2 – Vascular dementia, severe, with psychotic disturbance (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.C2 – Vascular dementia, severe, with psychotic disturbance
What it is
Use this code for severe vascular dementia caused by cerebrovascular disease, when psychotic disturbance is documented. It indicates advanced cognitive decline with a vascular cause and accompanying psychotic symptoms.
Clinical signs
Clinical features may include major memory and thinking impairment, loss of independence, and behavioral changes. Psychotic disturbance can include hallucinations or delusions; clinical features vary, refer to documentation.
When to use this code
Assign this code when the provider documents vascular dementia as severe and specifically notes psychotic disturbance. Use it for confirmed cases in which the psychotic symptoms are part of the dementia picture, not a separate disorder.
If the record does not clearly state severity or psychotic disturbance, check documentation before coding. Make sure the vascular etiology is supported and that the note distinguishes this from other dementia types.
Do not use for
Do not use it for vascular dementia without psychotic disturbance, or when severity is not documented. Do not apply it to delirium, primary psychotic disorders, or dementia of another cause.
Coding tip
Verify both “severe” and “with psychotic disturbance” in the provider’s documentation before assigning F01.C2.
