If a nursing facility resident with mental illness or intellectual disability is admitted to a hospital for a short time and then wishes to return to the facility, must a Level II evaluation be completed prior to her return to the facility?

July 1, 2018


There is no federal requirement that a Level II evaluation be completed prior to the individual returning to the nursing facility (NF). A Level II evaluation is required when there is a significant change in a resident’s condition. When a resident is returning from a hospital stay, there may be a clear change in condition. In instances where the significant change is evident, the individual would be subject to a Resident Review upon their return to the nursing facility, per CFR §483.106(b)(3).

What is the role of the Mental Health Authority in the dementia exclusion for mental illness?

July 26, 2017


The dementia exclusion for mental illness allows for the Level II evaluator to stop the evaluation if they determine that the diagnosis of dementia is primary and the mental illness (MI) diagnosis is secondary. It is important to note that the diagnosis or verification of a diagnosis of MI and dementia are Level II functions required to be conducted by mental health professionals and cannot be done by Level I reviewers. The identification of dementia must be done by the Level II evaluator as part of the diagnosis or verification of the diagnosis of MI.
