Role of Functional Assessment
In order to establish rehabilitative medical necessity and to guide a rehabilitation plan, the functional assessment must do two things:
- Describe how the person is functioning in each of the areas
- Describe how the mental illness is interfering with and impacting the functioning
- Descriptive data clearly describes how the person is functioning in each of the areas and clarifies how the symptoms of the mental illness are interfering and impacting the functioning in a life domain.
