The Medicaid statute provides several options for states to pay premiums for adults and children to purchase coverage through private group health plans, and in some case individual plans; in most cases, the statute conditions such arrangements on a determination that they are "cost effective." Cost effective generally means that Medicaid's premium payment to private plans plus the cost of additional services and cost sharing assistance that would be required would be comparable to what it would otherwise pay for the same services. Similar provisions also apply in the Children's Health Insurance Program (CHIP).
Under all these arrangements, beneficiaries remain Medicaid beneficiaries and continue to be entitled to all benefits and cost-sharing protections. States must have mechanisms in place to "wrap-around" private coverage to the extent that benefits are less and cost sharing requirements are greater than those in Medicaid. In addition under the statutory options in the individual market beneficiaries must be able to choose an alternative to private insurance to receive Medicaid benefits.
