How Medicaid Defines Low Income
Medicaid does not use a single national income number. Instead, it compares household income to the federal poverty level and applies state-specific limits. Whether someone qualifies depends on household size, composition, and the specific Medicaid category, such as adults, children, pregnant women, or people with disabilities.

Federal Poverty Level as a Benchmark
The federal poverty level, or FPL, is the standard reference. For 2024, the FPL for a single individual is about $15,060, and for a family of four it is about $31,200. Many states set Medicaid eligibility at or below 138% of the FPL for adults, but limits differ for children, pregnant women, and other groups.
State Variation and Expansion
States that expanded Medicaid under the Affordable Care Act generally cover adults up to 138% FPL. Non-expansion states often have much lower limits for adults without dependents or with limited medical conditions. Some states use modified income standards or count assets differently, which can change what counts as low income in practice.
Income That Counts
Medicaid counts wages, self-employment income, Social Security, pensions, unemployment, and certain other benefits. Some states exclude specific income types or apply deductions for medical expenses, childcare, or household members who are elderly or disabled. The exact treatment varies, so the same gross income can produce different results in different states.
Who Qualifies and How to Apply
Eligibility depends on the intersection of income, household composition, age, disability status, and citizenship or immigration status. People who fall below their state's threshold for their category may qualify even if their income is higher than they expect, especially if medical expenses reduce countable income. Applicants should check their state Medicaid agency or healthcare.gov for current limits and application routes.
| Factor | What It Affects | Context |
|---|---|---|
| Household size | Income threshold | Larger households have higher limits |
| State expansion status | Adult eligibility | Expansion states use 138% FPL |
| Category | Typical Limit | Notes |
| Adults in expansion states | Up to 138% FPL | Varies by state implementation |
| Pregnant women | Often higher than adults | Varies by state |
| Children | Often up to 200%+ FPL | Depends on CHIP and state rules |
| Non-expansion adults | Often below 100% FPL | Many states limit without dependents |
Why the Definition Matters
Medicaid is the primary safety net for low-income individuals and families, and its income definitions shape who can access coverage. Because limits change with FPL updates and state policy, checking the current year's rules in your state is essential before applying.
