Vascular dementia, mild, with mood disturbance

This code signifies a diagnosis of vascular dementia that is classified as mild in severity, and where the patient also exhibits mood disturbances. Vascular dementia is a cognitive decline caused by brain damage from impaired blood flow, and in this specific instance, the cognitive impairment is not severe enough to significantly impact daily living, but mood changes are present.

Use this code when documentation clearly states a diagnosis of mild vascular dementia accompanied by mood disturbance, such as depression, anxiety, or irritability. This code is appropriate when the physician's assessment confirms both the mild cognitive impairment due to vascular causes and the co-occurring mood symptoms.

• Ensure the documentation specifies "mild" severity for the vascular dementia and explicitly mentions "mood disturbance."
• Do not use this code if the dementia is moderate or severe, or if behavioral disturbances other than mood are the primary concern (e.g., psychotic features, agitation).
• Consider additional codes for the specific type of mood disturbance (e.g., F32.9 for major depressive disorder) if further detail is provided and clinically appropriate.
