The State Medicaid agency and the State CHIP agency may enter into an agreement with an Exchange established by the State under section 18031 of this title under which the State Medicaid agency or State CHIP agency may determine whether a State resident is eligible for premium assistance for the purchase of a qualified health plan under section 36B of the Internal Revenue Code of 1986 (and, if applicable, advance payment of such assistance under section 18082 of this title), so long as the agreement meets such conditions and requirements as the Secretary of the Treasury may prescribe to reduce administrative costs and the likelihood of eligibility errors and disruptions in coverage.
The State Medicaid agency and State CHIP agency shall participate in and comply with the requirements for the system established under section 18083 of this title (relating to streamlined procedures for enrollment through an Exchange, Medicaid, and CHIP).
The procedures established by State under paragraph (1) shall include establishing and having in operation, not later than January 1, 2014, an Internet website that is linked to any website of an Exchange established by the State under section 18031 of this title and to the State CHIP agency (if different from the State Medicaid agency) and allows an individual who is eligible for medical assistance under the State plan or under a waiver of the plan and who is eligible to receive premium credit assistance for the purchase of a qualified health plan under section 36B of the Internal Revenue Code of 1986 to compare the benefits, premiums, and cost-sharing applicable to the individual under the State plan or waiver with the benefits, premiums, and cost-sharing available to the individual under a qualified health plan offered through such an Exchange, including, in the case of a child, the coverage that would be provided for the child through the State plan or waiver with the coverage that would be provided to the child through enrollment in family coverage under that plan and as supplemental coverage by the State under the State plan or waiver.
Nothing in paragraph (1) shall limit or modify the requirement that the State assess an individual for purposes of providing home and community-based services under the State plan or under any waiver of such plan for individuals described in subsection (a)(10)(A)(ii)(VI).
