Medicaid covers a core set of medical services that every state must provide, plus additional benefits that vary by state. The program is jointly funded by the federal government and individual states, which means your exact coverage depends on where you live. However, the baseline is broader than many people expect, and nearly all states go well beyond the federal minimum.
Benefits Every State Must Provide
Federal law requires all state Medicaid programs to cover a specific list of services for enrolled adults. These are non-negotiable: no state can opt out of them. The mandatory benefits include:
- Inpatient hospital care, including room, board, nursing, and related services during a hospital stay
- Outpatient hospital services, such as emergency room visits, same-day surgeries, and hospital-based clinic visits
- Doctor and physician services, whether provided in an office, hospital, or other setting
- Laboratory and X-ray services for diagnostic testing
- Nursing facility services for adults 21 and older who need long-term institutional care
- Home health services for people who qualify for nursing facility care but receive services at home
- Family planning services and supplies
- Nurse midwife and certified nurse practitioner services
- Federally qualified health center and rural health clinic services
- Transportation to medical appointments (non-emergency medical transportation)
If you’re enrolled in Medicaid in any state, you have a legal right to these services. States set some of the specific rules around how much care you can receive (for example, how many hospital days per year), but they cannot eliminate any of these categories entirely.
Benefits That Vary by State
Beyond the mandatory list, states can choose from a long menu of optional benefits. This is where coverage differences between states become significant. Common optional benefits include prescription drugs, dental care, vision care (including eyeglasses), physical therapy, occupational therapy, speech therapy, hearing services, dentures, prosthetics, hospice care, personal care services, and private duty nursing.
The most important optional benefit to know about is prescription drugs. Although pharmacy coverage is technically optional under federal law, every state currently covers outpatient prescription drugs for Medicaid enrollees. In practice, you can count on having drug coverage, though each state maintains its own list of covered medications and may require you to try a lower-cost drug before approving a more expensive one.
Dental coverage is one of the biggest gaps. Some states offer comprehensive dental benefits for adults, others cover only emergency extractions or pain relief, and a few provide almost nothing. If dental care matters to you, it’s worth checking your specific state plan.
Preventive Care and Screenings
If you’re enrolled through Medicaid expansion (available in states that expanded eligibility to adults earning up to 138% of the federal poverty level), you get a full range of preventive services with zero out-of-pocket cost. This includes blood pressure screening, depression screening, alcohol misuse screening and counseling, obesity screening and counseling, and all routine adult vaccines recommended by the CDC. Women’s preventive care, including contraceptive services and well-woman visits, is also covered without cost-sharing.
For adults in traditional (non-expansion) Medicaid, states are encouraged but not always required to waive cost-sharing for preventive services. The practical difference is small in most states, since Medicaid copays are already very low, but expansion enrollees have the strongest federal protections here.
Mental Health and Substance Use Treatment
Medicaid is the single largest payer for behavioral health services in the United States. Coverage includes outpatient counseling, inpatient psychiatric care, and crisis services. States can also offer certified community behavioral health clinic services, which provide a comprehensive package of mental health and substance use treatment regardless of a person’s ability to pay.
For substance use disorders specifically, all state Medicaid programs are now required to cover medication-assisted treatment for opioid use disorder. This includes the medications themselves and associated counseling. That mandate was made permanent by federal law, so it applies in every state. Many states go further and cover treatment for alcohol use disorder and other substance use conditions as well.
Nursing Facility and Long-Term Care
Nursing home care is one of the most significant benefits Medicaid provides. States are required to cover nursing facility services for adults 21 and older who meet the state’s level-of-care criteria, and they cannot impose waiting lists for this benefit. That makes nursing home care one of the few long-term care services with guaranteed access once you qualify.
Inside a Medicaid-covered nursing facility, the facility must provide (at no extra charge to you) nursing and related medical services, rehabilitative services, social services, pharmaceutical services, individualized dietary services, an activities program, emergency dental care, and room and board. Routine personal hygiene items are also included.
Home and community-based services, which let people receive long-term care in their own homes or communities rather than in a nursing facility, are optional under federal law. Most states offer some version of these programs, but they frequently have waiting lists. In some cases, nursing facility care may be available sooner than home-based alternatives simply because the nursing home benefit carries a federal access guarantee that home-based services do not.
Pregnancy and Postpartum Coverage
Medicaid covers prenatal care, labor and delivery, and postpartum care. Historically, postpartum coverage ended 60 days after delivery. Starting in 2022, states gained the option to extend that to a full 12 months. As of early 2026, 49 states have implemented the 12-month postpartum extension, with one additional state planning to do so. This means nearly every Medicaid-enrolled parent now keeps full coverage for a year after giving birth, covering follow-up visits, mental health treatment, chronic condition management, and any complications that arise.
What You’ll Pay Out of Pocket
Medicaid has the lowest cost-sharing of any insurance program in the country. Most enrolled adults pay nothing at all for covered services. When states do charge copays, federal rules cap them at nominal amounts, typically a few dollars per service. Adults below the poverty line face the smallest possible charges, and many services (like preventive care, emergency care, and family planning) are exempt from copays altogether.
There is also a federal cap on total out-of-pocket spending. Your combined premiums and cost-sharing cannot exceed 5% of your household income in any given period. For most Medicaid enrollees, whose incomes are low by definition, this means annual out-of-pocket costs stay in the range of a few hundred dollars at most.
How to Find Your State’s Specific Benefits
Because states have so much flexibility in choosing optional benefits, two people on Medicaid in different states can have noticeably different coverage. The best way to see exactly what your state covers is to contact your state Medicaid agency directly or visit their website. You can also call the number on the back of your Medicaid card and ask for a summary of covered benefits. If you’re enrolled through a Medicaid managed care plan (as most adults are), the plan itself will have a member handbook listing every covered service, any limits, and whether you need a referral or prior authorization.
