Medicaid covers a broad range of mental health services, from therapy and psychiatric evaluations to inpatient hospitalization and substance use treatment. The exact list depends on where you live, because each state builds its own Medicaid plan on top of a federal baseline. Every state must cover certain core services, but many go further by adding options like residential treatment, peer support, and crisis intervention.
Services Every State Must Cover
Federal law requires all state Medicaid programs to cover a set of foundational mental health services when they are medically necessary. These include inpatient hospital services for psychiatric care, outpatient hospital services, physician services (including psychiatry visits), nursing facility services, and home health services. If you need mental health care that falls into one of these categories, your state cannot exclude it from coverage.
Since 2020, states are also required to cover medication-assisted treatment for opioid use disorder. This was made permanent in 2024, meaning every Medicaid program must pay for the medications used to treat opioid addiction, along with the counseling and behavioral therapy that go with it.
Optional Services That Vary by State
Beyond the federal floor, states can choose to cover additional mental health services. Most do, but the specifics differ significantly from one state to the next. Common optional services include:
- Individual and group therapy with licensed counselors, psychologists, or social workers
- Psychological testing and evaluations
- Residential treatment for mental health or substance use conditions
- Detox services
- Case management to coordinate care across providers
- Medication management visits with a prescriber
- Psychoeducational services that teach coping skills and self-management
- Respite care for caregivers of people with serious mental illness
To find out which of these your state covers, check your state Medicaid agency’s website or call the number on your Medicaid card. The benefits listed in your member handbook are your most reliable guide.
Broader Coverage for Children and Teens
Children and adolescents enrolled in Medicaid get a stronger set of protections through a benefit called Early and Periodic Screening, Diagnostic, and Treatment (EPSDT). This is one of the most important and least understood parts of Medicaid. It requires states to screen children for mental health conditions at regular intervals, provide diagnostic evaluations when a screening flags a concern, and then cover whatever treatment is medically necessary to address the condition, even if that service isn’t normally part of the state’s adult Medicaid plan.
In practical terms, this means a child on Medicaid can access services like applied behavior analysis, intensive outpatient programs, or therapeutic foster care if a provider determines they need it. States must evaluate medical necessity on a case-by-case basis. If your child has been denied a mental health service, it’s worth asking whether EPSDT applies, because it often expands what’s available beyond the standard benefits list.
Substance Use Disorder Treatment
Substance use treatment is covered under Medicaid as a behavioral health service, though the depth of coverage varies. All states now cover medications for opioid use disorder, including the office visits and counseling tied to that treatment. Many states also cover detox services, residential rehabilitation, outpatient counseling for alcohol and drug use, and intensive outpatient programs.
One important limitation applies to residential treatment. Federal Medicaid law generally prohibits the federal government from sharing costs when a Medicaid enrollee receives care in a large psychiatric or residential facility (defined as more than 16 beds), known as an Institution for Mental Disease. This rule has historically limited access to inpatient psychiatric care for adults between 21 and 64. However, many states have obtained special waivers from the federal government that allow them to cover short-term stays in these facilities for people with serious mental illness or substance use disorders. The waiver requires states to also invest in community-based alternatives, so the tradeoff is meant to improve the overall system. For people under 21, inpatient psychiatric services in these facilities are covered without a waiver.
Crisis Services
A growing number of states now cover community-based mobile crisis intervention through Medicaid. These are teams that respond to mental health emergencies in the community rather than routing people through emergency rooms. Since 2021, states have had the option to add these services to their Medicaid plans, and CMS awarded $15 million in planning grants to 20 states to help them set up these programs. If your state participates, you can access a mobile crisis team that comes to you, assesses the situation, and connects you to follow-up care.
Not every state has implemented this yet. If you’re unsure, calling the 988 Suicide and Crisis Lifeline can connect you to local crisis resources regardless of your insurance status.
Peer Support Services
Peer support, where someone with lived experience of mental illness or addiction recovery helps you navigate your own treatment, is now covered by Medicaid in almost every state. Peer support providers must be certified, though the specific training and certification requirements are set by each state. These providers are typically people who self-identify as being in recovery and who have completed a state-approved training program.
Peer support can look like one-on-one meetings to set recovery goals, help connecting to housing or employment resources, or coaching through difficult moments. It fills a gap that traditional clinical services sometimes miss, offering guidance from someone who has been through something similar.
Telehealth for Mental Health
Medicaid treats telehealth as a way to deliver services rather than a separate benefit category. This gives states wide flexibility in deciding how to handle it. Most states now reimburse therapists, psychiatrists, and other mental health providers for visits conducted by video or phone, but the rules around what types of telehealth are covered, which providers can bill for it, and whether it’s available statewide all differ by state.
If your state covers telehealth for mental health, your provider can bill Medicaid for the visit just as they would for an in-person appointment. Some states also reimburse for the technology costs involved. Where telehealth is not available, states must still ensure you can access covered services through in-person visits. This can be especially relevant in rural areas where mental health providers are scarce.
Finding Providers Who Accept Medicaid
Coverage on paper only matters if you can find a provider who accepts Medicaid. Federal law requires Medicaid managed care plans to maintain provider networks with enough mental health professionals to serve their enrolled members. States must consider factors like the number of providers accepting new Medicaid patients, travel distance and time, available transportation, and physical accessibility for people with disabilities.
Since 2016, states have been required to set time and distance standards specifically for behavioral health providers, both for adults and children. Plans must also ensure timely access based on the urgency of your need. If your managed care plan’s network can’t provide a necessary mental health service, the plan is required to cover out-of-network care at no extra cost to you.
In practice, finding an available provider can still be difficult. Starting with your plan’s online provider directory or member services line is the fastest route. If you’re having trouble getting an appointment within a reasonable timeframe, filing a complaint with your managed care plan or state Medicaid agency can sometimes accelerate the process, since plans are held to access standards they’re required to meet.
