(1) refer to the other agency, as appropriate, cases involving fraud, abuse, or insufficient quality of care under the state Medicaid program;
(2) maintain a log of cases referred to the other agency;
(3) share information with the other agency, subject to confidentiality requirements, including investigative reports on cases within the jurisdiction of both agencies; and
(4) collaborate with the other agency in the investigation of cases and the initiation of appropriate disciplinary action whenever possible.
