In contrast, the other groups listed—children under 19, pregnant women, and low-income seniors—have established pathways that frequently allow them to qualify for Medicaid regardless of whether a state has chosen to expand their Medicaid program. Each of these groups has specific eligibility criteria as outlined by federal and state laws aimed at ensuring access to health care for vulnerable populations.

Pregnant women can access Medicaid with coverage often available for those with incomes significantly above the Federal Poverty Line during pregnancy. Additionally, low-income seniors are eligible for Medicaid under both the aged and disabled categories, ensuring that older adults receive necessary health care services.
