Medicaid covers a broad range of medical services, from doctor visits and hospital stays to lab work and home health care. The exact list depends on where you live, because the program operates as a partnership between the federal government and individual states. Federal law sets a floor of services every state must provide, but states can add dozens of additional benefits on top of that baseline.
Benefits Every State Must Provide
Regardless of which state you live in, your Medicaid plan is required to cover a core set of services. These mandatory benefits include inpatient and outpatient hospital care, physician services, laboratory and X-ray services, and home health services. Nursing facility care for adults 21 and older is also mandatory, as are family planning services and supplies.
This federal floor means that even in states with leaner Medicaid programs, you can count on coverage for a hospital admission, a visit to your primary care doctor, diagnostic bloodwork, and basic imaging. States cannot impose waiting lists for nursing facility services the way they sometimes can for home-based alternatives.
Benefits That Vary by State
Beyond the mandatory list, states choose from a long menu of optional benefits. These are services the federal government allows Medicaid to cover but doesn’t require. Some of the most commonly added options include prescription drugs, dental care for adults, physical therapy, occupational therapy, speech therapy, eyeglasses, prosthetics, hospice care, and personal care services.
A few of these “optional” benefits are so widely adopted that they’re effectively universal. Prescription drug coverage is the best example. Technically optional under federal law, every state currently covers outpatient prescription medications for its Medicaid enrollees. Other optional benefits like adult dental care are far less consistent. Some states offer comprehensive dental coverage for adults, others cover only emergency extractions, and a few provide almost nothing. There are no minimum requirements for adult dental benefits, so the gap between states can be significant.
States can also offer case management, private duty nursing, respiratory care for ventilator-dependent individuals, community behavioral health clinic services, and home and community-based services as alternatives to institutional care. If a benefit matters to you and you’re comparing coverage across states, your state Medicaid agency’s website will list exactly which optional services it has adopted.
Children Get the Broadest Coverage
Medicaid covers children more comprehensively than adults through a benefit called EPSDT (Early and Periodic Screening, Diagnostic and Treatment). This applies to everyone under 21 enrolled in Medicaid, and it’s one of the most generous pediatric health benefits in the country.
EPSDT requires states to provide regular well-child checkups that include a full physical exam, developmental screening, vision and hearing tests, immunizations following the standard recommended schedule, and lead blood tests at 12 and 24 months. Any child between 24 and 72 months who missed a lead screening must also receive one. Dental care for children is mandatory and must cover at minimum pain relief, infection treatment, tooth restoration, and ongoing dental maintenance starting as early as needed. Medically necessary orthodontic services are also included.
The real power of EPSDT is what happens when a screening finds a problem. If a checkup reveals a health condition, the state must cover whatever treatment is needed to address it, even if that specific service isn’t normally part of the state’s Medicaid plan. This means a child’s coverage can extend to services that adult enrollees in the same state wouldn’t have access to.
Mental Health and Substance Use Treatment
Medicaid covers behavioral health services including psychotherapy, counseling, and inpatient mental health care. Substance use disorder treatment, including medication-assisted approaches, is also covered. Pre-existing mental health conditions cannot be excluded, and there are no yearly or lifetime dollar caps on these benefits.
Federal parity rules apply, meaning the financial and treatment limits on mental health and substance use services can’t be more restrictive than those placed on medical and surgical care. If your plan allows 30 visits for a physical condition, it can’t cap mental health visits at a lower number. The same principle applies to copayments, deductibles, and requirements for pre-authorization.
Nursing Homes and Long-Term Care
Medicaid is the single largest payer of long-term care in the United States. Nursing facility coverage is a mandatory benefit for adults 21 and older, covering three main categories: skilled nursing and medical care, rehabilitation for injuries or illness, and ongoing long-term care for people with chronic physical or mental conditions who need a level of support beyond what’s available in the community.
To qualify, you must meet your state’s “level of care” criteria, which evaluate whether you genuinely need the intensity of services a nursing facility provides. People with serious mental illness or intellectual disability go through an additional screening process to confirm that a nursing home is the appropriate setting rather than a community-based alternative.
Coverage only applies to facilities that are state-certified as Medicaid nursing facilities. Not every nursing home accepts Medicaid, so verifying certification matters before admission. Many states also offer home and community-based services as an alternative to nursing home placement, allowing people to receive personal care, case management, and other supports while staying in their own home. These programs often have waiting lists, unlike nursing facility services.
Transportation to Appointments
One benefit many people don’t realize exists is non-emergency medical transportation. Medicaid covers rides to and from medical appointments for enrollees who lack other means of getting there. This can include public transit vouchers, van services, or mileage reimbursement depending on how your state administers the benefit. If you’ve been skipping appointments because you can’t get a ride, contact your Medicaid plan to arrange transport.
What You’ll Pay Out of Pocket
Medicaid is designed to keep costs extremely low for enrollees, but it isn’t always completely free. States can charge small copayments or coinsurance for certain services, though federal rules cap these amounts. For people with incomes at or below 150% of the federal poverty level, copayments are limited to nominal amounts, often a few dollars. For those with slightly higher incomes, copays can be somewhat larger. Non-preferred prescription drugs, for instance, can carry a copayment up to 20% of the drug’s cost for people above that income threshold.
Several groups are largely shielded from out-of-pocket costs. Children and pregnant women are exempt from most copayments. Emergency services are exempt from all out-of-pocket charges regardless of who you are. And if you’re using the emergency room for a non-emergency issue, states may charge a higher copay to enrollees above 150% of the poverty level, but only under specific conditions.
Total out-of-pocket spending is capped, so even if your state does impose copays across multiple services, there’s a ceiling on what you’ll pay in a given year. The practical effect is that Medicaid coverage comes with far less financial exposure than most private insurance plans.
