Vascular dementia, unsp severity, with psychotic disturb

This code signifies a cognitive decline caused by cerebrovascular disease, where the severity of dementia is not specified, and the patient exhibits psychotic symptoms such as hallucinations or delusions. It indicates a significant impairment in cognitive function directly attributable to vascular brain injury, accompanied by a disruption in thought processes or perception.

Apply this code when documentation clearly states a diagnosis of vascular dementia with co-occurring psychotic features, but the physician does not specify the severity (e.g., mild, moderate, severe). This is appropriate when the medical record describes symptoms like paranoia, hallucinations, or delusions in a patient with a confirmed vascular etiology for their dementia.

• Ensure documentation explicitly links the psychotic disturbance to the vascular dementia, not a separate psychiatric condition.
• Avoid using this code if the severity of the vascular dementia is clearly documented; instead, choose a more specific F01.5- subcategory.
• Do not code psychotic symptoms separately if they are integral to the vascular dementia presentation as described by this code.
