The Department must offer an opportunity for informal dispute resolution concerning Department rules and standards before the advisory committee under subsection (b) of Section 2310-560 of the Department of Public Health Powers and Duties Law of the Civil Administrative Code of Illinois. Participants in this process must include representatives from the Department, representatives of the hospital, and additional representatives deemed appropriate by both parties with expertise regarding the contested deficiencies and the management of health care facilities. If the Department does not resolve disputed deficiencies after the informal dispute resolution process, the Department must provide a written explanation to the hospital of why the deficiencies have not been removed from the statement of deficiencies.
