"Section 1332 of the Patient Protection and Affordable Care Act (ACA; P.L. 111-148, as amended) provides states with the option to waive specified requirements of the ACA. In the absence of these requirements, the state is to implement its own plan to provide health insurance coverage to state residents that meets the ACA's terms. Under a state innovation waiver, a state can apply to waive ACA requirements related to qualified health plans, health insurance exchanges, premium tax credits, cost-sharing subsidies, the individual mandate, and the employer mandate. The state can apply to waive any or all of these requirements, in part or in their entirety. To obtain approval for a waiver application, a state must show that the plan it will implement in the absence of the waived provision(s) meets certain requirements. The state's plan must ensure that as many state residents have health insurance coverage under the plan as would have had coverage absent the waiver, and the coverage must be as affordable and comprehensive as it would have been absent the waiver. Additionally, the state's plan cannot increase the federal deficit. The Secretary of the Department of Health and Human Services (HHS) and the Secretary of the Treasury share responsibility for reviewing state innovation waiver applications and deciding whether to approve applications. The earliest a state innovation waiver could have gone into effect was January 1, 2017."
