An Overview of Medicaid Eligibility and Benefits

In This Article

Covering more than 72 million Americans, Medicaid is the largest health insurance provider in the United States. The program, created under the Social Security Act Amendments of 1965, is available to low-income individuals in the fifty states, the District of Columbia, and U.S. territories. It is a collaboration between federal and state governments to provide coverage for basic health care.

Understanding how it works can help you to make the most of its benefits.

What Medicaid Covers

Medicaid does not necessarily cover everything, but it covers a lot. The federal government requires that certain services be offered to all Medicaid beneficiaries.

These mandatory services include the following:

However, each state has the option to expand on those services—and they often do. These optional services may include but are not limited to:

Who Can Get Medicaid?

Many people with low incomes would be unable to afford health insurance without government assistance. This is where Medicaid comes into play. The U.S. Department of Health and Human Services (HHS) determines the federal poverty level (FPL) every year, and these values are used to set the eligibility standards for Medicaid.

Not everyone is eligible for Medicaid, however, even if they have a low income. They also must fall into certain categories that meet federal and state requirements.

The Centers for Medicare and Medicaid Services (CMS) mandates that the following groups be covered by Medicaid in all states:

  • Children newborn to 5 years old with family incomes up to 133% of the FPL
  • Children 6 to 18 years old with family incomes up to 100% of the FPL
  • Elderly individuals with an income up to 75% of the FPL
  • Families with dependent children with an income up to 11% to 68% of the FPL (based on a state's Aid to Families with Dependent Children income threshold)
  • Individuals with disabilities on Social Security Insurance (SSI) with income up to 75% of the FPL
  • Pregnant women with incomes up to 133% of the FPL

The federal government sets the standard, but individual states can choose to expand coverage beyond these limits. For example, they can increase income thresholds to include more people. You can learn more information about what your state program covers on the website.

Impact of the Affordable Care Act

The Affordable Care Act (ACA or Obamacare), enacted in 2010, had a significant impact on Medicaid eligibility, as it is what offered Medicaid Expansion to states. In exchange for federal funding, states agreed to expand Medicaid coverage to anyone with incomes up to 133% of the FPL, regardless of other factors. (Childless individuals would no longer be excluded from coverage.) The remaining states continue to follow the traditional Medicaid eligibility guidelines.

Immigration Status and Eligibility

Being an American citizen assures that you can get Medicaid coverage as long as the other requirements are also met. The same cannot be said for those with immigrant status.

States decide whether or not they will offer coverage to people who are not U.S. citizens. If they do, federal guidelines are to be followed. Legal immigrants residing in the country prior to 1996 may be eligible for full benefits. With the exception of those on SSI, legal immigrants entering the country after 1996 can only become eligible for full benefits after five years of residency.

There are exceptions for refugees and those granted asylum, currently or before becoming lawful permanent residents (green card holders).

Immigrants who have entered the country illegally may be eligible for emergency services only, not the full Medicaid benefit.

Medicaid vs. Medicare

Both of these health care programs are regulated by the CMS, but there are a lot of differences between them.


  • State run

  • Offers care to the elderly and those with disabilities

  • Offers care to low-income individuals of all ages, regardless health status

  • Provides long-term nursing home care to its beneficiaries


  • Federally run

  • Offers care to the elderly and those with disabilities

  • Limits nursing home care to short-term recovery after a hospital stay

More than 8 million people are eligible for both Medicaid and Medicare. These people are referred to as dual eligible. Medicaid helps them to pay for services that Medicare doesn't cover.
