Dementia

 Dementia

ICD-10-CM classifies dementia on the basis of: etiology, severity and associated behavioral disturbances. 

Etiology refers to the type of dementia. This can include:

    Vascular dementia F01

    Dementia in other diseases classified elsewhere F02

    Unspecified dementia F03

Severity includes mild, moderate and severe:

                Mild - Clearly evident functional impact on daily life, affecting mainly instrumental activities. No longer fully independent; requires occasional assistance with ADLs.

                Moderate - Extensive functional impact on daily life with impairment in basic activities. No longer independent; requires frequent assistance with ADLs.

                Severe - Clinical interview may not be possible. Complete dependency due to severe functional impact on daily life with impairment in basic activities, including basic self-care.

The diagnoses include options for associated behavioral disturbances: (5th-6th digits in code)

                0 = without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety

                11 = with agitation

                18 = with other behavioral disturbance

                2 = with psychotic disturbance

                3 = with mood disturbance

                4 = with anxiety

 

Also include documentation of:

Complications to dementia: Wandering Z91.83, Sundowning F05, restlessness, violence, delirium, etc.

 

Documentation tips:

Dementia should be linked to any known etiology with causal language, e.g. “Dementia due to Parkinson’s disease.” This documentation results in two codes: Parkinson’s G20, Dementia in diseases classified elsewhere F02.80.
