As policymakers debate next steps for expanding health insurance coverage and lowering health costs, some have introduced legislation that would broaden the role of public programs, such as Medicare and Medicaid. During the 115th Congress, eight such proposals were introduced, ranging from bills that would create a new national health insurance program for all U.S. residents, replacing virtually all other sources of public and private insurance (Medicare-for-All), to more incremental approaches that would create a new public plan option, as a supplement to private sources of coverage and public programs.

These eight legislative proposals differ in ways that have important implications for consumers, health care providers and payers, including employers, states, the federal government, and taxpayers. Key policy differences relate to eligibility, the size and scope of the public plan, covered benefits and cost sharing, premiums, subsidies for premium and cost sharing, cost containment strategies, and the likely interactions with current public programs and private sources of coverage. They also vary in their level of detail; some bills, according to their sponsors, are intended to serve as blueprints for reform, and are expected to include greater specificity over time. Given the timing of the legislative calendar, these bills are unlikely to advance in the current Congressional session; however, they illustrate the range of options that will likely serve as prototypes for legislation that may be introduced in the next session of Congress.

Greatly simplified, these public plan proposals fall into four general categories:

This policy brief summarizes key features of these proposals, highlights similarities and differences, and discusses key questions, trade-offs and potential implications. Several of these proposals have both a House and Senate sponsor; throughout the document, we refer to the sponsor who first introduced the legislation.
