Learn About Medicaid Programs Overview

What Medicaid Is and How It Works

Medicaid is a joint program run by the federal government and individual states that pays for medical care for millions of Americans. Unlike Medicare, which is based on age or disability regardless of income, Medicaid is designed primarily for people with lower incomes. Created in 1965, Medicaid has grown to cover over 72 million people across the United States as of 2023.

The program operates differently in each state because states have flexibility in how they design their programs within federal guidelines. This means the rules, covered services, and income limits vary significantly depending on where you live. For example, one state might cover dental care while another does not. Income thresholds that matter in one state may be different in another state nearby.

Medicaid pays healthcare providers directly for covered medical services. When you receive care from a provider that accepts Medicaid, you typically do not pay the full cost yourself. The state Medicaid program sends payment to the doctor, hospital, or other healthcare provider. This reduces the burden on individuals who might otherwise struggle to pay medical bills.

The program covers various types of healthcare including hospital care, doctor visits, prescription medications, dental work, mental health services, and long-term care. However, not all services are covered in every state, and coverage details differ. Understanding what your state covers is important for planning your healthcare.

Medicaid also includes special programs for specific groups. These include programs for children (CHIP - Children's Health Insurance Program), pregnant women, seniors, and people with disabilities. Each group may have different rules and coverage options.

Practical Takeaway: Medicaid coverage varies by state, so learning about your specific state's program rules, income limits, and covered services is the first step in understanding what programs that may help you or your family.

Income Limits and How States Set Them

Income limits are a key factor in determining who can participate in Medicaid programs. These limits are set as a percentage of the Federal Poverty Level (FPL). The FPL changes yearly based on inflation. In 2024, the federal poverty line for a single person is approximately $15,060 per year, and for a family of four, it is approximately $31,200 per year.

States have the power to set their own income limits within federal rules. The minimum federal requirement is that states cover adults up to 138% of the Federal Poverty Level, though this was optional following a 2012 Supreme Court decision. Some states go higher. For example, one state might cover adults earning up to 138% of FPL (about $20,800 for a single person in 2024), while another might cover those earning up to 175% of FPL (about $26,350 for a single person in 2024). A few states have set even higher limits.

Income is calculated in different ways depending on the program and your situation. Gross income (before taxes and deductions) is typically used, but some programs count net income. Self-employment income, rental income, and investment income all count. In some cases, child support payments or alimony count toward income limits. Understanding how your state counts income is important because it affects whether your income falls within program limits.

Family size matters significantly. A single person has a different income limit than a family of three or five. As family size increases, the income limit also increases. For instance, in a state that uses 138% FPL, a single person might have a limit of about $20,800, but a family of four might have a limit of about $43,100.

Income limits also vary by program type. The income limit for a parent in a state's Medicaid program might differ from the limit for a child in the CHIP program, or for a pregnant woman, or for a senior. Each category of person may have its own income threshold based on federal and state policy.

Practical Takeaway: To understand whether your household income level may fit within program parameters, find your state's specific income limits for the program category that applies to you (adult, child, pregnant woman, senior, or disability-based), and calculate your household's gross monthly or annual income according to your state's rules.

Types of Medicaid Programs and Coverage Options

Medicaid is not a single uniform program but rather a collection of programs, each with different rules and coverage. Understanding the main categories helps clarify which programs may apply to different people and situations.

Traditional Medicaid covers low-income individuals and families. This includes children, parents, pregnant women, seniors, and people with disabilities. Each group has different income and resource limits. Approximately 43 million people were enrolled in traditional Medicaid coverage in 2023.

The Children's Health Insurance Program (CHIP) is a separate but related program that covers children in families earning too much for Medicaid but not enough to afford private insurance. CHIP serves approximately 9.4 million children. The income limits for CHIP are typically higher than for adult Medicaid, making it possible for families with modest incomes to cover their children's healthcare.

Medicaid Expansion, allowed under the Affordable Care Act of 2010, extended coverage to more adults. States that adopted expansion cover adults earning up to 138% of the Federal Poverty Level, regardless of other factors. As of 2024, 40 states plus Washington D.C. have implemented expansion. The 10 states that have not are Alabama, Florida, Georgia, Kansas, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Wyoming. In expansion states, approximately 20 million additional people gained coverage.

Managed Care plans are how many states deliver Medicaid. Rather than paying providers directly for each service, states contract with health insurance companies (managed care organizations) to manage care for Medicaid members. Members typically choose or are assigned to a plan, select a primary care doctor, and coordinate care through that doctor. About 70% of Medicaid beneficiaries were in managed care plans as of 2022.

Fee-for-Service (FFS) Medicaid is the traditional model where the state pays providers directly for each service delivered. Some states still use this model, and some people in expansion states may have the option to stay in FFS rather than managed care.

Special programs exist for specific situations. Medicaid for the Blind, Medicaid for the Aged and Disabled, and various waiver programs that allow states to provide services outside normal Medicaid rules are examples. These programs may offer additional services or different rules than standard Medicaid.

Practical Takeaway: Identify which program category applies to you or your family (child, adult, pregnant woman, senior, person with disability), research whether your state has adopted Medicaid expansion, and learn whether your state uses managed care or fee-for-service models, as these factors affect which coverage options may be available to you.

What Medicaid Covers and What It Does Not

Medicaid covers many healthcare services, but coverage varies significantly by state and program. Federal law requires states to cover certain "mandatory" services. These include inpatient hospital care, outpatient hospital services, physician services, laboratory and X-ray services, home health services, nursing facility care for people 21 and older, early and periodic screening, diagnostic, and treatment (EPSDT) services for children, and family planning services.

Beyond these mandatory services, states can choose to cover "optional" services. Many states cover dental care, vision care, hearing aids, prescription drugs, mental health services, substance abuse treatment, and rehabilitation services. However, if a state chooses to cover an optional service, it must cover it for all Medicaid members, not just some. A state that covers dental care cannot limit it to only children or only adults.

Prescription drugs are covered in all state Medicaid programs as a mandatory service, though states can control costs by using formularies (lists of covered medications) and requiring prior authorization for certain drugs. Some medications may not be on the formulary, meaning Medicaid will not pay for them unless a doctor requests an exception.

Mental health and substance use disorder services have expanded significantly in recent years. All states must cover community mental health services. Many states also cover inpatient psychiatric care, outpatient counseling, medication-assisted treatment for opioid use disorder, and residential treatment programs, though details vary.

Services generally not covered by Medicaid include cosmetic surgery, most dental work for adults (though emergency dental is typically
