What Is Medicaid? Eligibility, ACA Expansion & CHIP (2024)

Medicaid is a joint federal-state program that provides free or very low-cost health insurance to low-income individuals and families. Unlike Medicare (which is age-based), Medicaid is needs-based. About 92 million Americans are enrolled. Each state runs its own Medicaid program within federal guidelines, so eligibility and covered services vary by state.

Who Qualifies for Medicaid?

Traditional Medicaid covers specific groups: low-income families, pregnant women, children, people with disabilities, and elderly individuals. The ACA added a new pathway:

GroupIncome Limit (approx.)Notes

CHIP: Children's Health Insurance Program

CHIP covers children in families who earn too much for Medicaid but can't afford private insurance. Key facts:

  • Covers children up to age 19
  • Income limits typically 200%–300%+ FPL (varies dramatically by state; some states up to 400%)
  • Low or no premiums, minimal copays
  • Comprehensive coverage: doctor visits, dental, vision, hospital care, prescriptions
  • Some states offer CHIP for pregnant women

How to Apply

Apply through your state's Medicaid agency or HealthCare.gov. You can apply any time—Medicaid has no open enrollment period. If your income drops due to job loss, you can enroll immediately. Applications are often processed within 45 days (90 days for disability-based cases).

10 states haven't expanded Medicaid

If you live in a non-expansion state (TX, FL, GA, etc.) and earn below 100% FPL, you may fall into the "coverage gap"—too much income for traditional Medicaid but not enough for Marketplace subsidies (which start at 100% FPL). Check your state's specific rules at Medicaid.gov.
