Short answer: Usually not. Texas did not expand Medicaid under the ACA, so an adult under 65 who is not pregnant, disabled or raising a child generally cannot get Texas Medicaid at any income level.
Texas Medicaid is built around categories, not income alone: children, pregnant women, very-low-income parents and caretaker relatives, former foster youth, and people who are aged, blind or disabled. Texas has no ACA adult (expansion) group, so a healthy adult without dependent children usually has no Medicaid pathway however low the income.
That leaves many low-income Texas adults in the “coverage gap”: too poor for Marketplace premium tax credits and not in a Medicaid category. Screen each household member separately, because the children in the same family may still qualify for Children’s Medicaid or CHIP even when no adult does.
