The Arizona health care cost containment system is established consisting of contracts with contractors for the provision of hospitalization and medical care coverage to members. Except as specifically required by federal law and by § 36-2909, the system is only responsible for providing care on or after the date that the person has been determined eligible for the system, and is only responsible for reimbursing the cost of care rendered on or after the date that the person was determined eligible for the system. Additionally, the statute orders the administrator of this program to establish peer review and utilization review for all contractors within the system
