Medicaid remains the backbone of mental health and substance use disorder treatment in the U.S., covering nearly one-third of all adults with serious mental illness (SMI) and nearly one-quarter of adults with substance use disorders (SUD). Yet as states have expanded access to critical services—including Certified Community Behavioral Health Clinics (CCBHCs), Assertive Community Treatment (ACT), and Coordinated Specialty Care for First Episode Psychosis (CSC-FEP)—a looming fiscal reckoning threatens to unravel these gains.

New federal work requirements for Medicaid expansion enrollees, enacted in the 2025 reconciliation law, are projected to disenroll tens of thousands of individuals with behavioral health needs—disrupting continuity of care for a population already struggling with access barriers. Meanwhile, state budgets, still recovering from the pandemic and inflationary pressures, are bracing for higher spending on mental health services without guaranteed federal reimbursement increases.

For patients, providers, and policymakers, the question is urgent: Can states sustain the hard-won expansions in behavioral health coverage, or will fiscal constraints force painful rollbacks? The stakes could not be higher, as untreated mental illness and addiction drive rising emergency room visits, homelessness, and criminal justice system involvement.

Why Medicaid’s Role in Behavioral Health Is Non-Negotiable

Medicaid is not just a safety net—It’s the primary payer for behavioral health services in the U.S. According to the Kaiser Family Foundation (KFF), the program finances:

• Nearly 30% of all adults with serious mental illness (SMI), including those with schizophrenia, bipolar disorder, and major depression.
• Over 20% of adults with substance use disorders (SUD), with Medicaid covering nearly half of all adults with opioid use disorder (OUD).
• Critical medications, such as antipsychotics, mood stabilizers, and buprenorphine for opioid dependence, which are often unaffordable without public insurance.

These figures reflect a system under strain. Before the Affordable Care Act (ACA) expanded Medicaid eligibility in 2014, millions of low-income Americans with mental health or addiction issues were uninsured. Even today, 40% of non-elderly adults with SMI remain uninsured or underinsured, per a 2025 SAMHSA report. Medicaid fills this gap—but its future is now in flux.

Expansion Efforts: CCBHCs, ACT, and CSC-FEP as Lifelines

In response to decades of underfunding and fragmented care, states have increasingly turned to three evidence-based models to improve access:

1. Certified Community Behavioral Health Clinics (CCBHCs)

A federal demonstration program launched in 2013, CCBHCs provide integrated mental health and substance use treatment under a single roof, with mandatory 24/7 crisis services. Since 2024, 10 additional states have joined the CCBHC expansion, bringing the total to 30 states and territories participating in the program, according to the Centers for Medicare & Medicaid Services (CMS).

CCBHCs have shown promising results: A 2023 study in Psychiatric Services found that patients in CCBHCs had 30% fewer emergency department visits and 40% lower hospitalization rates compared to traditional care models. Yet participation remains uneven—only about 1 in 5 counties with high behavioral health needs have a CCBHC, leaving rural and underserved areas behind.

2. Assertive Community Treatment (ACT)

ACT teams deliver intensive, community-based care to individuals with SMI who are at high risk of hospitalization or homelessness. Medicaid covers ACT through state waivers, but funding varies widely. For example:

• California’s Medicaid program reimburses ACT teams at $120 per member per month, while New York’s rate is $150—a disparity that affects team size and caseload capacity.
• A 2025 study in Psychiatric Services found ACT reduced hospitalizations by 50% for participants compared to standard care.

However, Medicaid’s inadequate reimbursement rates for ACT—often below the cost of providing services—have led some states to cap enrollment or reduce team sizes.

3. Coordinated Specialty Care for First Episode Psychosis (CSC-FEP)

CSC-FEP programs, like the NAVIGATE model, provide early intervention for young adults experiencing their first psychotic episode. Medicaid covers these services through state innovation waivers, but only 12 states have active CSC-FEP programs, per the Treatment Advocacy Center.

Research shows CSC-FEP can reduce hospitalizations by 60% and improve employment outcomes—but participation is limited by Medicaid’s lack of standardized coverage requirements. Without federal mandates, states decide whether to fund these programs at all.

The Fiscal Pressure: Work Requirements and Coverage Losses

The 2025 federal reconciliation law introduced a major shift: work requirements for Medicaid expansion adults, effective January 1, 2026. These requirements apply to:

• Non-disabled adults aged 19–59 in expansion states.
• Individuals who must demonstrate employment, job training, or community service for at least 80 hours per month to retain coverage.

For people with SMI or SUD, these rules pose a double bind:

• Symptom severity: Many cannot work due to illness, yet exemptions are limited.
• Treatment dependency: Medication adherence and therapy are critical for recovery—but work requirements may force them to choose between employment and care.
• Disproportionate impact: A Commonwealth Fund analysis projects that 1 in 5 Medicaid enrollees with SMI could lose coverage under these rules.

States are already seeing the fallout. In Arkansas and New Hampshire, where work requirements were implemented in 2024, over 10,000 enrollees have been disenrolled—with behavioral health specialists warning of increased ER visits and untreated relapses. The Health Resources & Services Administration (HRSA) has flagged these states for higher-than-expected psychiatric hospitalizations among disenrolled individuals.

Who Is at Risk—and What Happens Next?

The fiscal pressures on Medicaid behavioral health coverage are not just about work requirements. Three additional threats loom:

1. Federal Funding Cuts

The Inflation Reduction Act (IRA) of 2025 included $5 billion in new Medicaid funding for behavioral health—but only through 2027. Without congressional reauthorization, states face budget shortfalls of up to $3 billion annually for mental health services, per the Congressional Budget Office (CBO).

2. Provider Burnout and Shortages

Medicaid’s low reimbursement rates—often 30–50% below private insurance—have led to a 20% decline in psychiatrists accepting Medicaid patients since 2020, according to the American Medical Association (AMA). This shortage is acute in rural areas, where only 1 in 10 counties has a psychiatrist.

3. The Opioid Crisis Backslide

Medicaid covers 45% of all adults with opioid use disorder (OUD), yet only 30% receive medication-assisted treatment (MAT), per the 2023 NSDUH report. Work requirements threaten to reduce MAT enrollment by 25%, reversing progress in overdose deaths, which rose 2% in 2025 after years of decline.

What’s Being Done—and What’s Next?

Advocates, states, and federal agencies are scrambling to mitigate the damage:

• State waivers: Some states (e.g., Oregon and Vermont) are seeking Section 1115 waivers to exempt behavioral health enrollees from work requirements.
• Federal pushback: The HHS Office of National Drug Control Policy has urged CMS to delay work requirements for OUD patients until 2027.
• Legislative fixes: The Medicaid Behavioral Health Access Act (introduced in March 2026) would mandate federal matching funds for CCBHCs and ACT programs, but it faces opposition in Congress.

The next critical deadlines:

• June 1, 2026: CMS must finalize guidance on Medicaid work requirement exemptions for behavioral health.
• July 2026: States must submit 2027 fiscal year budgets, which will determine funding for CCBHCs and ACT programs.
• September 2026: The CMS Office of Management and Budget will release data on Medicaid disenrollment rates by diagnosis.

Key Takeaways

• Medicaid is the dominant payer for mental health and SUD treatment, covering 1 in 3 adults with SMI.
• CCBHCs, ACT, and CSC-FEP have improved outcomes but face funding gaps and uneven state adoption.
• Work requirements risk disenrolling tens of thousands with behavioral health needs, worsening treatment gaps.
• Federal funding for expansions expires in 2027, leaving states to fill the gap with limited budgets.
• Providers are leaving Medicaid due to low reimbursements, exacerbating access crises in rural areas.

What You Can Do

If you or a loved one rely on Medicaid for mental health or substance use treatment:

• Check your state’s Medicaid work requirement rules and exemptions.
• Contact your local CCBHC or ACT team for enrollment assistance.
