Medicaid is a federal-state program primarily for which of the following groups?

Medicaid is primarily designed to assist individuals with limited income and resources, making it especially beneficial for vulnerable populations. The program targets various groups, but it is particularly focused on the blind and disabled, as well as low-income families and children. The inclusion of the blind and disabled in the Medicaid program stems from the need to provide essential healthcare services and support for those who may struggle to afford medical care due to their disabilities.

While individuals over 65, such as those who qualify for Medicare, may also be covered under Medicaid if they meet specific income thresholds, the core aim of Medicaid is to address the needs of those who are disabled or blind. This targeting helps ensure that individuals who require additional healthcare support due to their conditions are not left without adequate coverage.

The other options do not accurately reflect the primary scope of Medicaid. Individuals with high-income status and those with premium health insurance are generally not eligible for Medicaid assistance, as the program is intended for those with lower incomes who cannot afford healthcare. Thus, the correct answer reflects the program's primary focus on providing critical healthcare support to those with disabilities and blindness.
