Earlier this year, California submitted a proposal to renew its Section 1115 waiver, which is due to expire at the end of October. The state is currently negotiating with the federal government over the terms and conditions of this waiver renewal. In this post, we examine key issues and concerns related to the availability of federal funding for California’s proposal. The post provides a primer on how Section 1115 waivers are generally financed, an overview of California’s proposal, and a discussion of the challenges the proposal faces within that financing structure.
