Vascular dementia, mild, with other behavioral disturbance

This code signifies a form of dementia caused by cerebrovascular disease, presenting with mild cognitive impairment. Patients exhibit noticeable, but not severe, decline in memory, language, or executive function, accompanied by behavioral issues beyond typical cognitive decline, such as agitation, aggression, or psychosis.

Assign this code when documentation clearly indicates a diagnosis of vascular dementia that is mild in severity and includes specific mentions of other behavioral disturbances. Supporting documentation should detail both the cognitive deficits and the specific behavioral symptoms observed.

• Ensure the physician explicitly documents "mild" severity for the vascular dementia.
• "Other behavioral disturbance" requires specific mention of behaviors like agitation, aggression, or psychotic features, not just general cognitive decline.
• Do not use this code if the behavioral disturbance is specified as "psychotic disturbance" or "mood disturbance," as separate codes exist for those specific presentations.
