The AZ Medicaid program administration shall coordinate benefits provided under this article to a member so that any costs for services payable by the system are costs avoided or recovered from any available third party payor. The administration may require that the program contractors are responsible for the coordination of benefits provided pursuant to this article. The system shall act as a payor of last resort for members unless specifically prohibited by federal law. If the administration determines that according to federal guidelines it is more cost effective for a person defined as eligible under § 36-2934 to be enrolled in a group health insurance plan in which the person is entitled to be enrolled, the administration shall pay all of that person’s premiums, deductibles, coinsurance and other cost sharing obligations for services covered under § 36-2934. The person shall apply for enrollment in the group health insurance plan as a condition of eligibility under § 36-2934.
