F01.51 ICD-10-CM

ICD-10-CM code F01.51 describes vascular dementia with behavioral disturbance. Vascular dementia accompanied by agitation, psychosis, mood, or other behavioral symptoms. It is a billable, specific code valid for claim submission. It is grouped under the “Neurocognitive & Organic Disorders” section of the mental, behavioral, and neurodevelopmental disorders chapter.

When to use F01.51

Assign a code in this group when a mental or behavioral disturbance is caused by a known physiological condition, such as delirium, dementia, or another organic mental disorder. Base the selection on the documented medical workup and the specific cognitive or behavioral presentation. For F01.51 specifically, vascular dementia accompanied by agitation, psychosis, mood, or other behavioral symptoms.

Documentation & billing

Document the underlying etiology, the cognitive or behavioral findings, and whether a behavioral disturbance is present. Pair with an etiology code (for example Alzheimer disease G30.9 or a cerebrovascular code) when the cause is identified.

Common pitfalls

• Coding dementia without documenting whether a behavioral disturbance is present.
• Omitting the underlying etiology code when the cause is known.
• Confusing acute delirium (F05) with chronic dementia.
