What Medicaid Is and How It Works

Medicaid is a health insurance program run jointly by the federal government and individual states. Unlike Medicare, which is based on age or disability, Medicaid is primarily based on income level. The program was created in 1965 as part of the Social Security Act and has grown to cover millions of people across the United States.

Each state operates its own Medicaid program within federal guidelines, which means the specific rules, covered services, and income limits vary from state to state. This is an important distinction—what qualifies for coverage in one state may differ in another. For example, in 2023, states had different income thresholds for parents, children, and pregnant individuals seeking coverage under their programs.

Medicaid covers a range of health services including doctor visits, hospital stays, prescription medications, mental health treatment, and long-term care services. The federal government requires all state programs to cover certain "mandatory" services, but states can also choose to cover additional "optional" services. Some states cover vision care and dental services, while others may not include these benefits.

The program serves approximately 72 million people in the United States, making it one of the largest health insurance programs in the country. This includes children, adults, seniors, and people with disabilities. Medicaid also plays a significant role in funding nursing home care and other long-term care services, covering roughly 40% of all long-term care costs nationally.

Practical Takeaway: Understanding that Medicaid is state-specific helps you know where to find accurate information—your state's Medicaid agency website will have the most relevant details about what's available where you live.

Income Limits and Financial Thresholds Across States

Medicaid income limits are set by each state and determine whether someone's household income falls within the range for potential coverage consideration. These limits are expressed as a percentage of the Federal Poverty Level (FPL). For example, a state might set its income limit at 138% of the FPL for parents, meaning a family's income can be up to 138% of the federal poverty threshold and still potentially be within range.

As of 2024, the Federal Poverty Level for a family of four is approximately $31,200 per year. If a state sets its limit at 138% FPL for parents, that family would need to earn less than roughly $43,056 annually to potentially be considered. However, many states have different limits for different groups—children may have higher income thresholds than parents, and pregnant individuals may have different limits than other adults.

The variation among states is substantial. As of early 2024, states that expanded Medicaid under the Affordable Care Act (ACA) generally cover adults earning up to 138% of FPL. However, 10 states have not expanded Medicaid, meaning they maintain lower income limits for adults. In these non-expansion states, adults may need to earn considerably less to potentially be considered for coverage, sometimes as low as 50% of FPL depending on the state.

Income calculations in Medicaid programs typically include wages, self-employment income, Social Security benefits, unemployment benefits, child support, and other regular income sources. However, certain items are often not counted as income, such as some types of gifts, tax refunds, and certain disability payments. States use different methodologies for calculating income, which is why reviewing your specific state's rules matters.

Some states use "categorical" limits, meaning different income thresholds apply to different groups like children, pregnant women, parents, and disabled individuals. Other states use "modified adjusted gross income" (MAGI) methods for calculating income, which more closely mirrors federal tax calculations. Understanding which method your state uses helps you understand how your household income relates to potential coverage.

Practical Takeaway: Visit your state's Medicaid website and look for a chart or table showing current income limits for different household sizes and member types—this single piece of information is the starting point for understanding coverage possibilities in your area.

Different Medicaid Programs and Categories

Medicaid is not a single, one-size-fits-all program. Instead, it consists of multiple categories, each with different rules and coverage options. Understanding these categories helps you identify which one might be relevant to your situation.

Children have been covered under Medicaid since its creation, and this remains a major category. The Children's Health Insurance Program (CHIP), created in 1997, expanded coverage for children in families earning too much for traditional Medicaid but not enough to afford private insurance. Together, Medicaid and CHIP cover approximately 41 million children in the United States. Some states allow children in families earning up to 400% of the Federal Poverty Level through CHIP.

Pregnant individuals and new parents also have coverage categories. Pregnant women can potentially receive Medicaid coverage for pregnancy-related services and delivery, even if they don't otherwise meet income requirements. After childbirth, coverage for the new mother typically ends within 60 days in most states, though some states have extended this period. Newborns are typically covered for the first year of life if their mother was on Medicaid during pregnancy.

Elderly individuals and people with disabilities represent another major category. Medicaid covers nursing home care and home and community-based services for seniors and disabled persons. Many elderly individuals use Medicaid to pay for long-term care expenses after their personal resources are exhausted. Approximately 17% of Medicaid spending goes to seniors and disabled individuals, but they represent a smaller portion of total beneficiaries—showing that their care is more intensive and costly.

Adults in states that have expanded Medicaid under the ACA can potentially receive coverage if they earn up to 138% of the Federal Poverty Level, regardless of whether they have dependents or disabilities. This represents coverage for able-bodied, working-age adults—a significant expansion that began in 2014 and has been adopted by 40 states plus Washington D.C. as of 2024.

Supplemental Security Income (SSI) recipients—primarily very low-income elderly, blind, and disabled individuals—may also receive Medicaid coverage. SSI is a federal cash assistance program, and in most states, SSI recipients are automatically eligible for Medicaid.

Practical Takeaway: Identify which category best describes your situation (child, pregnant, elderly, disabled, or working-age adult), then look for that specific category's rules on your state's Medicaid website to get targeted information.

Covered Services and Healthcare Benefits

Medicaid programs must cover certain mandatory services that all states are required to provide. These include doctor visits, hospital care, laboratory and X-ray services, nursing facility services, and Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) services for children. EPSDT is a comprehensive benefit that covers preventive care, diagnostic services, and treatment for children under 21, including dental care, vision care, and hearing services in this age group.

Beyond mandatory services, states can choose to cover optional services, and many do. Common optional services include prescription medications, dental care for adults, vision care, mental health and substance use disorder treatment, rehabilitation services, and medical equipment and supplies. As of 2023, most states cover prescription drugs through Medicaid, but coverage rules and the list of covered medications vary.

Mental health and substance use disorder treatment coverage has expanded significantly. The Mental Health Parity and Addiction Equity Act requires that mental health and substance use disorder benefits be covered at the same level as medical and surgical benefits. This means if Medicaid covers hospital stays, it should cover inpatient mental health treatment in similar ways. Many states now cover medication-assisted treatment for opioid use disorder, including methadone and buprenorphine.

Medicaid covers long-term care services, which is a major distinguishing feature compared to private insurance. This includes nursing facility care, home health services, and home and community-based services (HCBS) waivers that allow people to receive services in their own homes and communities rather than institutions. Medicaid paid for approximately 48% of all long-term care costs in the United States in 2021.

Reproductive health services are covered, including contraception, pregnancy-related care, and delivery services. Postpartum care is covered for 60 days after childbirth in most states, though some states have extended this period. Family planning services are also typically covered.
