ICD-10 Code F01.B0 – Vascular dementia, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F01.B0 – Vascular dementia, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety
What it is
This code identifies moderate vascular dementia caused by cerebrovascular disease. Use it when documentation confirms dementia severity is moderate and no behavioral, psychotic, mood, or anxiety disturbance is present.
Clinical signs
Typical findings include impaired memory, slowed thinking, and reduced ability to manage daily activities, with a vascular pattern of cognitive decline. Clinical features vary; refer to documentation.
When to use this code
Use F01.B0 when the provider documents vascular dementia and specifically states the condition is moderate. The record should also state that behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety are absent.
If the note describes dementia from prior strokes or other cerebrovascular disease, this code may fit. Check documentation for severity and for any associated behavioral or psychiatric features before assigning it.
Do not use for
Do not use this code if the dementia is mild or severe, or if any behavioral, psychotic, mood, or anxiety disturbance is documented. Check documentation if the type of dementia is uncertain.
Coding tip
Always match the documented severity and all excluded disturbances before coding F01.B0.
