Learn About Medicaid Age Requirements and Eligibility

Understanding Medicaid Age Requirements by State

Medicaid is a joint federal and state program that provides health coverage to millions of Americans. Unlike Medicare, which is primarily for people age 65 and older, Medicaid does not have a specific age requirement that applies everywhere. Instead, each state sets its own rules about age within federal guidelines. This means the age requirements for Medicaid coverage differ significantly depending on where you live.

The federal government sets a baseline, but states have flexibility to expand coverage to different age groups. Some states cover children up to age 19, while others extend coverage to age 26 for certain groups. For adults without children, age requirements vary widely—some states cover adults as young as 19, while others have different thresholds. Understanding your state's specific rules is the first step in learning about potential coverage options.

According to the Centers for Medicare & Medicaid Services (CMS), as of 2024, 38 states have expanded Medicaid to cover adults earning up to 138% of the federal poverty level, regardless of age (with some variations). In these expansion states, adults of working age may have coverage options they might not have in non-expansion states. The federal poverty level for 2024 is $15,060 annually for an individual, meaning expanded states often cover adults earning around $20,782 per year.

Non-expansion states maintain more restrictive rules, often limiting adult coverage to people with disabilities, parents of dependent children, or pregnant women. In these states, a working adult without children may not find coverage options through Medicaid, even if their income is low. This creates a significant gap in coverage across the country, affecting millions of people.

Practical takeaway: Before exploring other details about Medicaid, determine whether your state has expanded Medicaid. Visit your state's Medicaid website or contact your state health department to learn the specific age and income rules that apply where you live. This single step will clarify which coverage pathways may be available to you.

Medicaid Coverage for Children and Teenagers

Children represent one of the largest groups covered by Medicaid nationwide. Federal law requires states to cover children from birth through age 18 if they meet income limits set by each state. However, the income limits vary significantly. In some states, children in families earning up to 200% of the federal poverty level may have coverage options, while other states use lower thresholds. For 2024, 200% of the poverty level equals about $42,120 for a family of four.

Many states go beyond this federal minimum. The Children's Health Insurance Program (CHIP), a companion program to Medicaid, covers children in families earning too much for Medicaid but not enough to afford private insurance. CHIP coverage is available in all 50 states and the District of Columbia. In 2023, approximately 10.7 million children were covered through CHIP, according to CMS data. Some states combine CHIP and Medicaid into a single program, while others keep them separate.

For teenagers specifically, coverage extends through age 18 in all states that receive federal Medicaid funding. However, what happens at age 19 depends on your state. Some states cover certain teenagers through age 20 or 21 under special programs. Additionally, young adults ages 19-26 may remain on a parent's private health insurance plan under the Affordable Care Act—but Medicaid coverage at these ages is state-specific and generally available only to those with disabilities or other qualifying conditions in most states.

Medicaid coverage for children includes preventive services, doctor visits, hospitalizations, prescription medications, mental health services, and dental care. The scope of covered services is broader for children than for some adult populations. Newborns are automatically covered for the first month of life if born to a Medicaid-covered mother, providing important protection during vulnerable early days.

Practical takeaway: If you have children or are a teenager, research your state's specific income limits and coverage rules. Many families don't realize their children may have coverage options because they haven't checked their state's CHIP program. Income limits for children are often higher than for adults, so it's worth investigating even if adult family members don't qualify.

Medicaid for Adults: Age-Based Coverage Differences

Adult coverage under Medicaid has expanded significantly since 2014 when the Affordable Care Act took effect, but the details vary dramatically by state. In Medicaid expansion states, adults age 19-64 with income up to 138% of the federal poverty level may have coverage options, regardless of whether they have children or disabilities. This represents roughly 50 million adults nationwide who gained coverage options through expansion.

However, adults in non-expansion states face a much narrower path to Medicaid. In these states, coverage for non-disabled adults is typically limited to parents of dependent children, and even then, income limits are often very low. For example, some non-expansion states cover parents only if they earn less than 50% of the federal poverty level—about $7,530 per year for a family of three. This creates what's sometimes called the "coverage gap," where working adults earn too much to qualify for Medicaid but too little to afford private insurance.

Age 65 is a critical threshold where coverage rules change. Once people reach 65, they generally become eligible for Medicare, the federal health insurance program for seniors. However, some people remain on Medicaid alongside Medicare (called "dual eligible") because Medicaid helps pay Medicare premiums and covers services Medicare doesn't, like long-term care. States must cover people age 65 and older who meet income and resource limits, making this one of the few areas where Medicaid rules are truly uniform nationwide.

For adults ages 19-64, the specific rules in your state determine coverage possibilities. Some states have additional programs beyond standard Medicaid expansion. For instance, some states cover specific populations like breast cancer survivors, or they have special pathways for working people with disabilities. Understanding both the age and income rules for your state is essential for determining coverage options.

Practical takeaway: Adults in their working years should check whether their state has expanded Medicaid and what specific income limits apply. Don't assume you know the rules—state websites provide calculators or contact information to help you understand your situation. If you're approaching age 65, begin learning about Medicare at least three months before your birthday, even if you're currently on Medicaid.

Pregnant Women and Postpartum Coverage

Pregnancy creates a special category in Medicaid rules across all 50 states. Federal law requires states to cover pregnant women and women in the postpartum period, regardless of their family structure. This means a pregnant woman without children, living alone, may still have Medicaid coverage options in her state. Pregnant women also have higher income limits than other non-elderly, non-disabled adults in most states.

The postpartum coverage period was extended in 2023 through legislative changes. Previously, postpartum coverage lasted only 60 days after the end of pregnancy. Now, states are required to provide coverage for 12 months after pregnancy ends (including miscarriage, abortion, or stillbirth). As of January 2024, most states have implemented this extended postpartum period, though the exact date of implementation varies. This change affects hundreds of thousands of women annually and represents one of the most significant recent changes to Medicaid eligibility rules.

Income limits for pregnant women are often significantly more generous than for other groups. While a non-pregnant, non-disabled adult might be covered at 100% of the federal poverty level in an expansion state, pregnant women might be covered at 200% or higher of the poverty level. For 2024, this could mean a pregnant woman earning around $42,120 annually might have coverage options in some states.

Coverage for pregnant women includes prenatal care, labor and delivery, and postpartum care. Medicaid also covers family planning services and contraception, which can be accessed even before becoming pregnant. For women with existing health conditions, Medicaid coverage during pregnancy ensures access to ongoing management and treatment.

Practical takeaway: If you are pregnant or recently gave birth, contact your state Medicaid office immediately to learn about coverage options, even if you previously didn't qualify. The extended 12-month postpartum period means more women and families can maintain continuous coverage during this critical time. Don't wait—pregnancy-related coverage often has different rules and timelines than other Medicaid programs.
