Description: There has been a proliferation of proposals to expand access to public health insurance plans, either to strengthen insurance markets under the Affordable Care Act (ACA) or to replace the ACA marketplaces or other health insurance programs altogether. These proposals range from creating a public plan that would operate alongside private plans in the ACA marketplaces, to allowing individuals to buy into Medicare or Medicaid, to expanding Medicare to all. The terms used to describe these various options are often used interchangeably but they would be structured differently and have different impacts depending on the implementation details. Panelists at this session will discuss the general approaches for expanding access to public plans and their potential implications.
