A year ago, on July 4, 2025, the One Big Beautiful Bill Act (OBBBA, H.R.1) was signed into law. The fireworks were literal; the damage to the U.S. mental health system is still unfolding. This is not a forecast anymore. The projections are becoming lived reality. Here is what has actually happened — and what is still in motion.
The Law That Is Already Reshaping Who Gets Care
The OBBBA enacted the largest reduction to Medicaid in American history: a $1 trillion cut — 15% — to federal Medicaid funding over the next decade. The nonpartisan Congressional Budget Office estimates 11.8 million people will lose Medicaid coverage directly; NAMI’s analysis, factoring in secondary effects, puts the number at roughly 17 million. Why does this matter for mental health specifically? Because Medicaid is the single largest payer of behavioral health services in the United States — covering approximately one in four dollars spent on mental health and substance use treatment. Among Medicaid enrollees, 35% of adults have a mental illness and 24% have a substance use disorder, rates far exceeding the general population.
The cuts target the very people who need the system most.
The consequences are already visible in hospital psychiatric units. Between 2023 and 2024 — before the law was even signed — 126 hospitals across the U.S. shut down their inpatient psychiatric units. These units already operated at a loss; at some hospitals, up to 80% of psychiatric inpatients are Medicaid-covered. The OBBBA removes their primary payer’s funding floor while simultaneously limiting states’ ability to use “state directed payments” to top up provider reimbursement above Medicare rates. The result: facilities that were barely surviving are now facing existential pressure.
New work requirements — requiring Medicaid recipients to document employment or community engagement to maintain coverage — take effect in phases. People with a “disabling mental disorder” are formally exempted, but APA Services warns that requiring individuals with serious mental illness to affirmatively document their exempt status will discourage enrollment and cause coverage lapses. As the Milbank Memorial Fund analysis documents, Medicaid expansion under the ACA had driven meaningful declines in overdose deaths and increases in treatment rates — progress that the OBBBA is now structurally reversing.
The SAMHSA Crisis: A Preview of What Instability Looks Like
On January 13–14, 2026, the behavioral health field got a 24-hour preview of what defunding looks like in practice. SAMHSA sent termination notices to between 2,000 and 2,900 grantees covering approximately $2 billion in federal grants — roughly a quarter of the agency’s budget. The grants targeted included treatment for pregnant and postpartum women, peer recovery support, HIV prevention programs, reentry services for people leaving incarceration, and Strategic Prevention Framework projects. No prior warning. No explanation tied to program performance. SAMHSA’s own staff were caught unaware.
Within 24 hours, after national outcry, HHS Secretary Robert F. Kennedy Jr. reversed the decision and restored all grants. But as iCarol’s detailed analysis noted: the immediate financial risk was removed, but the demoralization, planning chaos, and loss of trust in federal funding reliability are not so easily undone. Providers who had been halfway through four-year grant periods began contingency planning that has not stopped.
The administration has separately proposed dissolving SAMHSA entirely, merging it with the Health Resources and Services Administration into a new “Administration for a Healthy America,” with an additional $1 billion in proposed cuts to community mental health centers, suicide prevention initiatives, SUD treatment, and behavioral health workforce training. Congress has not enacted this restructuring — the FY2026 Consolidated Appropriations Act, as PA Providers reports, funded SAMHSA at $7.4 billion, relatively level with prior years. Congress also inserted new language requiring three days’ notice before any future grant termination. That is a check — but a thin one against an executive branch that has demonstrated its willingness to act abruptly.
Parity: The Promised Protection That Isn’t Being Enforced
In May 2025, the Trump administration announced it would not enforce the strengthened mental health parity regulations finalized in September 2024. Those rules — years in the making — would have required insurers to prove, using outcomes data and independent medical standards, that mental health benefits were genuinely comparable to medical and surgical benefits in practice, not just on paper. The rules were suspended following a legal challenge from the ERISA Industry Committee, representing large employers who objected to the compliance cost.
The suspension remains in force as of July 2026. The underlying Mental Health Parity and Addiction Equity Act (MHPAEA) remains law, but without the 2024 regulatory teeth, its practical enforcement against non-quantitative treatment limitations — prior authorization barriers, inadequate networks, restrictive medical necessity criteria — is dramatically weakened. Millions of insured Americans who depend on mental health parity protections do not currently have effective regulatory enforcement standing behind their coverage.
What’s Actually Moving in the Right Direction (Narrowly)
It would be incomplete not to note: the White House signed an executive order on April 18, 2026 directing ARPA-H to allocate at least $50 million from existing funds to support state programs advancing psychedelic treatments for serious mental illness — an acknowledgment, at least, that novel treatment modalities deserve federal investment. The $50 million is reallocated from existing budgets, not new appropriations, and its scope is narrow. Representative Jamie Raskin’s bipartisan STOP Suicide Act and 9-8-8 Connect Act, introduced in March 2026, represent genuine legislative intent — but both remain in the introductory stage with no committee votes reported.
The System Being Dismantled Was Already Failing People
It is worth saying plainly: the U.S. mental health system before the OBBBA was not a functioning system. Wait times were months long. Workforce shortages were chronic. Psychiatric bed capacity had been in freefall for decades. The OBBBA did not create these failures — it accelerated them, at the precise moment when post-pandemic mental health demand hit record levels and overdose deaths were beginning, for the first time in years, to decline.
The advocacy community — NAMI, MHA, APA, AFSCME, and hundreds of local organizations — fought this legislation hard and continues to fight its implementation. Their work matters. State policy now becomes the primary lever: states that strengthen their own parity laws, maintain behavioral health as a protected Medicaid benefit category, and resist the most damaging federal signals will diverge sharply from those that do not. That divergence is already underway.
Accountability requires honesty: what is happening to U.S. mental health funding and policy right now is not a course correction. It is a dismantling.
