What This Code Means

Mid-stage dementia caused by reduced blood flow to the brain with behavioral problems other than agitation.

Coding Tips

•Use this code for behavioral disturbances such as wandering, inappropriate sexual behavior, or personality changes
•Document the specific behavioral manifestations to support the diagnosis and treatment plan

Clinical Significance

Moderate vascular dementia with other behavioral disturbance captures intermediate-stage vascular cognitive decline with non-agitation behavioral symptoms such as wandering, sundowning, hoarding, or inappropriate behaviors. At the moderate stage, these behaviors often necessitate increased supervision and environmental modifications.

Documentation Requirements

✓Diagnosis of vascular dementia with cerebrovascular etiology
✓Severity explicitly documented as 'moderate'
✓Specific behavioral disturbance described (not agitation)
✓Cognitive testing supporting moderate impairment
✓Functional assessment and supervision needs
✓Environmental safety modifications implemented or recommended
✓Behavioral management plan

Use Additional Code

code, if applicable, to identify wandering in vascular dementia (Z91.83)
