Medicaid covers the bottom of the range in Louisiana
Louisiana expanded Medicaid, so there is no coverage gap here: adults under 138% of the poverty guideline — about $22,025 for one person — go to Medicaid rather than falling between it and the subsidy.
333,790 under-65 Louisiana residents are uninsured all the same, 9.2% of them — 23rd of the 51 states and DC, and 0.9× the 26-state median of 9.9%.
