ICD-10 Code F01.A4 – Vascular Dementia, Mild, with Anxiety (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.A4 – Vascular dementia, mild, with anxiety
What it is
This code identifies mild vascular dementia with documented anxiety. Use it when cognitive decline is linked to vascular disease and the record also supports an anxiety symptom or disorder.
Clinical signs
Typical findings include impaired memory, slowed thinking, executive dysfunction, and reduced ability to manage daily tasks. Anxiety may appear as nervousness, worry, restlessness, or similar documented symptoms; clinical features vary, refer to documentation.
When to use this code
Use F01.A4 when the provider documents mild vascular dementia and specifically notes anxiety in the same encounter. It is appropriate when the anxiety is part of the dementia diagnosis or clearly associated with it. If the record does not support mild severity or anxiety, check documentation.
Do not use for
Do not use this code for vascular dementia without anxiety, or for anxiety alone without documented dementia. Do not assign it if the chart describes a different dementia type or the severity is not mild.
Coding tip
Verify both the dementia type and severity, and confirm that anxiety is explicitly documented before assigning F01.A4.
