Which state has the highest coverage gap among those not expanding Medicaid?

Texas has the highest coverage gap among states that have not expanded Medicaid under the Affordable Care Act (ACA). The coverage gap refers to the situation where individuals earn too much to qualify for traditional Medicaid but not enough to qualify for subsidies to purchase health insurance on the marketplace.

In Texas, a significant number of low-income residents fall into this gap primarily because the state opted not to expand Medicaid, which would have provided coverage for many more low-income individuals and families. Other states that have not expanded Medicaid, like Florida, Georgia, and North Carolina, do have notable coverage gaps, but Texas's population size and the proportion of uninsured residents contribute to it having the largest gap.

This situation underscores the impact of state-level decision-making regarding Medicaid expansion and its consequential effects on health coverage availability for vulnerable populations.
