Medicaid provides free or very low-cost health coverage that includes doctor visits, hospital stays, prescription drugs, mental health care, and much more. It is the largest source of health coverage in the United States, and its benefits go well beyond basic medical care. For many enrollees, especially children, pregnant women, and people with disabilities, Medicaid covers services that most private insurance plans either limit or exclude entirely.
Core Medical Services Every State Must Cover
Federal law requires every state Medicaid program to cover a specific set of services, regardless of where you live. These mandatory benefits include inpatient and outpatient hospital care, physician visits, lab work and X-rays, nursing facility care, and home health services. Family planning services, nurse midwife care, and certified nurse practitioner services are also guaranteed.
One benefit that often surprises people is non-emergency medical transportation. Every state must help Medicaid enrollees get to and from medical appointments, which removes a barrier that keeps many low-income people from receiving care in the first place. Medication-assisted treatment for opioid and other substance use disorders is also a mandatory benefit, covering the specific medications used to treat addiction alongside counseling and behavioral therapy.
Beyond these federal requirements, states can add optional benefits like dental care for adults, vision services, physical therapy, and prescription drugs. In practice, all 50 states and Washington, D.C., cover outpatient prescription drugs through the Medicaid Drug Rebate Program, which requires drug manufacturers to offer rebates in exchange for Medicaid covering their products. This keeps drug costs extremely low for enrollees.
Minimal Out-of-Pocket Costs
The financial protection Medicaid offers is one of its most significant benefits. While states can charge small copayments or premiums, these costs are capped at levels far below what you would see with private insurance. For enrollees with incomes at or below 150 percent of the federal poverty level (about $21,150 a year for a single person in 2025), copayments are limited to nominal amounts, often just a few dollars per service.
Certain groups pay even less. Children and pregnant women are exempt from most out-of-pocket costs. Copayments for prescription drugs are capped at nominal amounts for lower-income enrollees, though states can charge up to 20 percent of a drug’s cost for non-preferred medications if your income is above 150 percent of the poverty level. Total out-of-pocket spending for any Medicaid household cannot exceed 5 percent of family income, a ceiling that prevents medical costs from becoming unmanageable.
Children’s Coverage Is Uniquely Comprehensive
Medicaid’s benefits for children stand apart from nearly every other insurance program in the country, thanks to a requirement called Early and Periodic Screening, Diagnostic, and Treatment, or EPSDT. This benefit applies to everyone under 21 enrolled in Medicaid and requires states to provide comprehensive preventive care and to treat any condition that screening uncovers, even if that specific service is not otherwise covered in the state’s Medicaid plan.
Screening services include a full developmental history, a comprehensive physical exam, all recommended immunizations, lead toxicity blood tests at 12 and 24 months, and health education for families. Children between 24 and 72 months who missed earlier lead screenings must also receive one. Vision services include eye exams, glasses, and treatment for vision problems on a regular schedule. Hearing services cover screening, diagnosis, and hearing aids when needed.
Dental coverage for children on Medicaid must include pain relief, infection treatment, tooth restoration, ongoing dental maintenance starting as early as necessary, and orthodontic services when medically required. If any screening reveals a physical or mental health condition, the state must provide whatever treatment is needed to correct or improve it. This makes EPSDT one of the most expansive pediatric health benefits available anywhere in the U.S. health system.
Long-Term Care and Home-Based Services
Medicaid is the primary payer for long-term care in the United States, covering nursing home stays that would otherwise cost tens of thousands of dollars a year out of pocket. But the program has shifted significantly toward helping people stay in their own homes and communities rather than moving into institutions. In 2021, 86.2 percent of people receiving long-term services through Medicaid were getting home and community-based care, and 63.2 percent of all long-term care spending went toward those services.
Home and community-based services can include personal care assistance with daily tasks like bathing and dressing, home modifications, adult day care, and respite care for family caregivers. These services allow older adults and people with disabilities to remain in familiar surroundings while still receiving the support they need. For families caring for a loved one with a chronic condition or disability, this benefit can be transformative.
Mental Health and Substance Use Treatment
Medicaid covers a broad range of behavioral health services, and its role in treating substance use disorders has expanded considerably. Since federal law now requires every state to cover medication-assisted treatment as a mandatory benefit, people enrolled in Medicaid can access the specific medications proven most effective for opioid use disorder, along with counseling and recovery support. Many states have gone further, using waivers and demonstration programs to cover residential treatment, peer support services, and other recovery-oriented care that fills gaps traditional insurance often leaves open.
Mental health services, including therapy, psychiatric care, and crisis intervention, are available through Medicaid in every state. For children under 21, EPSDT requires treatment for any mental health condition identified during screening, making Medicaid a critical safety net for youth mental health care.
Preventive Care Without Cost Sharing
For adults who gained Medicaid coverage through expansion (available in most states to adults earning up to 138 percent of the federal poverty level), preventive services come with no copays or cost sharing at all. These include all screenings and immunizations recommended by major federal advisory bodies: cancer screenings, blood pressure checks, diabetes screenings, cholesterol tests, depression screenings, recommended vaccines, and more. This zero-cost preventive care makes it far easier to catch health problems early, when they are cheaper and simpler to treat.
Pregnancy and Postpartum Coverage
Medicaid covers a significant share of all births in the United States, and its benefits for pregnant women are extensive. Prenatal visits, labor and delivery, and postpartum care are all covered, along with nurse midwife and freestanding birth center services. Tobacco cessation counseling for pregnant women is a mandatory benefit. Pregnant women are also exempt from most cost sharing.
Historically, pregnancy-related Medicaid coverage ended 60 days after delivery, a gap that left many new mothers without insurance during a medically vulnerable period. A growing number of states have now extended postpartum coverage to a full 12 months, and federal policymakers have recommended making this extension permanent. During the extended postpartum period, the federal government covers 100 percent of the cost, removing the financial barrier for states to offer it.
Protection Against Medical Debt
Beyond covering specific services, Medicaid enrollment has a measurable impact on financial health. Research from the University of Michigan found that enrollees in the state’s Medicaid expansion program saw their medical debt in collections drop by an average of $983 per person over seven years. Even more striking, the share of enrollees with subprime credit scores fell by 23 percentage points over the same period. Medical debt is the most common type of debt in collections in the U.S., and Medicaid’s low cost-sharing structure directly prevents the kind of surprise bills and unaffordable charges that push people into financial hardship.
For a family of four in 2025, Medicaid eligibility in expansion states reaches household incomes up to about $44,367 a year (138 percent of the federal poverty level). Children often qualify at higher income thresholds. If you fall within these ranges, Medicaid’s combination of comprehensive coverage, minimal out-of-pocket costs, and protection from medical debt makes it one of the most valuable public benefits available.
