ICD-10 Code F01.A11 – Vascular dementia, mild, with agitation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.A11 – Vascular dementia, mild, with agitation
What it is
This code identifies mild vascular dementia with documented agitation. It applies when cognitive decline is caused by vascular disease and the chart specifically notes agitation.
Clinical signs
Typical findings include mild memory or thinking problems with evidence of vascular brain injury, such as a history of stroke or ischemic disease. Agitation may appear as restlessness, irritability, or disruptive behavior; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents vascular dementia, mild severity, and agitation together in the same encounter. It is appropriate when the record clearly links the dementia to vascular causes and identifies agitation as an associated behavioral feature.
If the note describes dementia without severity or without agitation, check documentation before assigning this code. You should not infer agitation from general confusion, anxiety, or delirium unless the provider states it.
Do not use for
Do not use this code for nonvascular dementia, unspecified dementia, or vascular dementia without mild severity. Also avoid it when agitation is not documented or is better explained by another condition; check documentation.
Coding tip
Code only when both mild vascular dementia and agitation are explicitly documented together.
