Which states have opted out of Medicaid expansion?

The states that have opted out of Medicaid expansion are Texas and Florida. This decision stems from various political and economic considerations unique to each state. Texas, for instance, has historically favored limited government intervention in healthcare, leading to resistance against expanding Medicaid under the Affordable Care Act. Florida has also opted not to expand Medicaid, often citing concerns over the costs and implications for the state's budget as reasons for its decision.

In contrast, other state options provided do not accurately reflect states that have opted out. California and New York, for example, have embraced Medicaid expansion, seeking to increase coverage for lower-income residents. Similarly, Nebraska and Idaho have taken steps towards expansion, although their paths and specific implementations may vary. Ohio and Michigan have both participated in Medicaid expansion, leveraging federal funds to extend eligibility to more residents. Thus, B is correct as it identifies states that have not participated in this aspect of Medicaid reform.
