The Patient Protection and Affordable Care Act (ACA) ushered in the largest sea change to the US health care system in decades. Yet, states remain the laboratories of health system reform and transformation, experimenting with new delivery and payment models, often involving Medicaid programs as drivers of state health care system change.
Learn more about what is happening in states across the country with the following resources, which include state plan documents, analyses, summaries, and tools. Also included is information on the Centers for Medicare and Medicaid Innovation (CMMI, or Innovation Center), which was created by the ACA and provides funding to states in their health system transformation work. CMMI funding comes in several forms, including Model Pre-Design Awards, Model Design Awards, and Model Testing Awards. You will also find information on the Centers for Medicare and Medicaid Services (CMS) Medicaid Innovation Accelerator Program.
