Eliminates requirements that Medicaid benchmark benefits: (1) provide minimum essential coverage, and (2) ensure parity in the financial requirements and treatment limitations in medical and surgical benefits, on the one hand, and mental health or substance use disorder benefits, on the other.

Amends the Patient Protection and Affordable Care Act (PPACA) to eliminate: (1) the extension of the Medicaid premium assistance subsidy to all individuals, regardless of age; and (2) the prohibition against any state requirement, as a condition of Medicaid eligibility, that an individual (or the individual's parent) apply for enrollment in qualified employer-sponsored coverage.

Amends SSA titles XIX and XXI (Children's Health Insurance Program) (CHIP) to eliminate the modified adjusted gross income standard for determining Medicaid and CHIP eligibility.

Amends SSA title XXI to: (1) eliminate the increased FMAP for CHIP; (2) reduce CHIP appropriations for FY2013 and eliminate them for FY2014-FY2015; (3) repeal the requirement that a state assure exchange coverage for targeted low-income children unable to be provided child health assistance as a result of funding shortfalls; (4) terminate after FY2013 (instead of the current extension through FY2015) the period during which the Secretary of Health and Human Services (HHS) must make grants to improve CHIP outreach and enrollment; and (5) reduce the amount of money for awarding such grants.

Reduces the amount of the one-time appropriations to CHIP under the Children's Health Insurance Program Reauthorization Act of 2009 (CHIPRA).

Amends the Internal Revenue Code to repeal the tax credit for premium assistance for coverage under a qualified health plan.

Amends PPACA to require a state's American Health Benefit Exchange to certify that, for purposes of the individual responsibility penalty under the Internal Revenue Code, an individual is exempt from the individual requirement to purchase qualified health care insurance (mandate) or from the penalty imposed by such section because the individual would have qualified for premium assistance under the Internal Revenue Code, medical assistance under Medicaid, child health assistance under CHIP, or reduced costing sharing, but for the enactment of this Act.
