ICD-10 Code F01.A0 – Vascular dementia, mild, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.A0 – Vascular dementia, mild, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety
What it is
This code identifies mild vascular dementia caused by cerebrovascular disease, with no documented behavioral, psychotic, mood, or anxiety disturbance. Use it when the record shows dementia symptoms linked to vascular injury and the severity is mild.
Clinical signs
Clinical features vary; refer to documentation. Mild dementia usually includes measurable cognitive decline that affects complex tasks but preserves much daily independence, and the chart should not document associated behavioral or psychiatric disturbance.
When to use this code
Use F01.A0 when the provider documents vascular dementia and clearly states it is mild. It also applies when the note specifies absence of behavioral, psychotic, mood, and anxiety symptoms. If severity or associated disturbances are not stated, check documentation before coding.
Do not use for
Do not use this code for vascular dementia with behavioral disturbance or any psychotic, mood, or anxiety disturbance. Also avoid it if the dementia type is unspecified or if another cause of dementia is documented.
Coding tip
Confirm both the vascular etiology and the “mild” severity in the provider note before assigning F01.A0.
