Learn About Medicaid Programs and Coverage Options

Understanding the Basics of Medicaid

Medicaid is a joint federal and state health insurance program that provides coverage to millions of Americans. Unlike Medicare, which is primarily for people age 65 and older, Medicaid serves people of all ages who meet certain income and other requirements. The program was created in 1965 as part of the Social Security Act and has grown to cover approximately 72 million people as of 2023.

Each state runs its own Medicaid program within federal guidelines, which means coverage options, income limits, and services vary significantly by location. What is covered in one state may differ substantially from another state's program. This state-by-state variation is important to understand because it means you'll need to look at your specific state's rules rather than assuming national rules apply to your situation.

Medicaid covers a broad range of services including hospital care, doctor visits, prescription medications, mental health services, dental care, vision care, and long-term care services. Some services are mandatory across all states, while others are optional and determined by individual states. For example, all states must cover emergency services, but coverage of dental care varies—some states offer comprehensive dental coverage while others offer limited or no dental services.

The program is funded through a combination of federal and state taxes. The federal government pays a percentage of costs (called the Federal Medical Assistance Percentage, or FMAP) which varies by state based on per capita income. Wealthier states typically receive a lower federal match, while less wealthy states receive a higher match. In 2023, federal funding ranged from 50% to approximately 78% depending on the state.

Medicaid also serves as a safety net for vulnerable populations. Approximately 38% of Medicaid beneficiaries are children, though they account for only about 17% of total program spending. The program also covers a significant portion of long-term care costs, including nursing home care, which can be extremely expensive for families to manage alone.

Practical Takeaway: Before learning about coverage specifics, identify which state you live in or plan to move to, as Medicaid rules and coverage options are different in each state. You can find your state's Medicaid agency through the Centers for Medicare & Medicaid Services (CMS) website at cms.gov.

Income and Financial Requirements Across Different States

Income limits are one of the primary factors that determine who may participate in Medicaid, though these limits vary considerably by state and category of coverage. Income is typically measured as a percentage of the Federal Poverty Level (FPL). In 2024, the federal poverty level for a single person is approximately $14,600 annually, and for a family of four it is approximately $30,000 annually.

States have flexibility in setting their own income thresholds. As of 2023, most states that have expanded Medicaid coverage (which became optional following the 2010 Affordable Care Act) allow coverage for adults with incomes up to 138% of the Federal Poverty Level. This means a single person in an expansion state could potentially have income up to roughly $20,157 per year. However, non-expansion states may have much lower limits—sometimes as low as 40-50% of the federal poverty level, or around $6,200 for an individual.

It's important to understand that "income" for Medicaid purposes isn't always the same as your gross income. Most states use Modified Adjusted Gross Income (MAGI), which counts most of your income but may exclude certain things like some types of support for disabled individuals or tribal income. Some Medicaid categories, particularly for elderly and disabled individuals, may use different income counting rules that allow for deductions of medical expenses or other costs.

Resource limits also apply in many Medicaid programs, particularly for seniors and people with disabilities. Resources typically include savings accounts, investments, property (excluding your home), and vehicles. In 2024, the general resource limit for an individual is $2,000, and for a couple it's $3,000, though these limits vary by program and state. Your primary home and one vehicle are usually not counted toward the resource limit.

Some states have implemented Medicaid expansion, which significantly increased income limits for adult coverage. The Medicaid expansion was optional under the Affordable Care Act, so as of 2024, about 39 states plus Washington D.C. have adopted expansion, while 12 states have not. This creates a coverage gap in non-expansion states where some adults earning too much for traditional Medicaid but not enough to afford marketplace insurance may have limited options.

Practical Takeaway: Look up your state's specific income and resource limits on your state Medicaid website. Note that if your income changes, you may need to report this change, as it could affect your coverage. Write down your state's income limit for your household size to use as a reference when reviewing your situation.

Categories of Medicaid Coverage

Medicaid includes several distinct coverage categories, each with its own rules and requirements. Understanding which category you might fit into helps clarify what coverage might be available. The main categories include children, pregnant people, parents and caretakers, elderly individuals, and people with disabilities.

Children's Medicaid coverage is one of the largest categories. All states cover children under age 19 in families with incomes at or below 139% of the Federal Poverty Level at minimum, though many states cover children at much higher income levels—some up to 400% of poverty level or more. As of 2023, approximately 27 million children were covered by Medicaid. Children's coverage typically includes preventive care, immunizations, dental care, vision care, and treatment for illness or injury. Many states also cover children through age 19 and some through age 20.

Pregnant people and new parents have special coverage categories in most states. Pregnant people can often access Medicaid at higher income levels than other adults in non-expansion states. Coverage for pregnant people and during the postpartum period typically includes prenatal care, delivery, and postpartum care. In 2022, 42% of all births in the United States were covered by Medicaid. As of 2024, the federal government extended postpartum coverage from 60 days to 12 months in all states.

Elderly individuals (typically age 65 and older) may be covered by Medicaid if they have limited income and resources, even if they also have Medicare. This group is sometimes called "dual eligible" when they have both programs. Medicaid can cover costs that Medicare doesn't pay, such as long-term care, which is particularly important for this population. Medicaid covers approximately 6.1 million seniors.

People with disabilities represent another major Medicaid category. Individuals receiving Supplemental Security Income (SSI) are usually automatically covered by Medicaid in many states. Even those not receiving SSI may be able to access Medicaid through disability programs. Additionally, some states offer coverage for people with specific conditions such as HIV/AIDS or cystic fibrosis. People with disabilities and chronic conditions often need substantial medical services, and Medicaid covers many of these services including long-term care and supports.

Many states also offer optional categories such as coverage for people transitioning out of foster care, coverage for certain workers with disabilities, or coverage for individuals with specific medical conditions. These options vary significantly by state.

Practical Takeaway: Identify which Medicaid category your situation most closely matches. This will help you understand what your state requires and what services might be available. Write down the category and check your state's website for the specific rules that apply to it.

Services and Coverage Details

Medicaid covers a wide range of medical services, though what's covered can differ by state and sometimes by which Medicaid category you're in. Federal law requires all states to cover certain "mandatory" services. These mandatory services include inpatient hospital care, outpatient hospital services, physician services, laboratory and x-ray services, skilled nursing facility services, home health services, prenatal care, and family planning services. Every state must provide these basic services to their Medicaid beneficiaries.

Beyond mandatory services, states may choose to cover "optional" services. These optional services include dental care, vision care, hearing aids, mental health services beyond the basics, rehabilitation services, and transportation to medical appointments. While these are optional for states, many states do offer them. For example, as of 2023, 50 states and Washington D.C. cover some form of dental services, though the extent
