Key Takeaways
- Behavioral health demand has outpaced every other care category over the past six years. Visit volume rose 62.6% between 2018 and 2024, with ABA specifically growing 309.2% since dedicated CPT codes took effect in 2019, the report’s stand-alone case study in behavioral health vulnerabilities.
- The workforce cannot meet need, and federal parity enforcement has been paused. The national mental health professional adequacy rate sits at 27.3%, and the Trump Administration has discontinued enforcement of the Mental Health Parity Rule even as the FY 2027 Budget Request proposes consolidating HRSA, SAMHSA, CDC, and OASH into a new Administration for a Healthy America.
- Deal volume reflects the demand-supply gap and is accelerating into 2026. The sector recorded 167 behavioral health transactions in 2025, anchored by Spring Health’s pending acquisition of Alma (expected Q2 2026 close) and Universal Health Services’ announced acquisition of Talkspace in March 2026.
- Trilliant’s structural argument points operators toward value-based reorientation. The combined picture of demand, supply, parity retrenchment, and pricing variance reframes the industry around a common standard of value for money, a shift payers are already pushing through utilization scrutiny and outcomes-based contracting.
The number of data stories in Trilliant Health’s 2026 Behavioral Health Report runs past 50, and the one that investment bankers and autism services operators will spend the most time with sits on page 48. Between the introduction of dedicated CPT codes in 2019 and the end of 2025, ABA visit volume grew 309.2%. The report’s authors, led by Chief Research Officer Allison Oakes, Ph.D., treat this not as a success story but as a warning shot: an example, in their framing, of how fee-for-service incentive structures combined with a newly codeable service line can produce growth that outpaces the clinical and regulatory infrastructure meant to oversee it.
The authors write that Medicaid-driven growth in particular has drawn scrutiny from payers and policymakers who question whether the trajectory reflects genuine unmet need or patterns of overutilization and, in some cases, fraud. That framing matters. It is the analytic scaffolding underneath the wave of MassHealth audit activity, Indiana Medicaid’s phased rate reduction, and CareSource’s 20% rate cut for Georgia ABA providers that Acuity has been tracking across the ABA beat. The Trilliant report is unusual among payer-facing industry analyses in putting that scrutiny inside the same evidence base as the growth numbers themselves.
The tension the report maps is the one M&A advisors and provider operators have been navigating in fragments: escalating demand meeting a provider workforce, coverage regime, and affordability structure that are not scaling with it. Oakes, in a statement accompanying the April 14 release, called behavioral health “America’s preeminent public health challenge.”
The specific demand numbers in the report are more precise than most headline versions of this story have captured. The 62.6% overall utilization increase is calculated on a rate basis (visits per 1,000 commercially insured people) rather than raw visit counts, so comparisons to primary care volumes require careful sourcing. What the report does establish with national all-payer claims data is that growth is broad-based across diagnoses. Anxiety disorder visits rose 89.3% between 2018 and 2024. Behavioral and emotional disorders, the category the report defines to include ADHD and conduct disorders, grew 51.0%. Among children specifically, pervasive developmental disorders (the category that includes autism) grew 93.0%, and speech and language developmental disorders accounted for 240.3 visits per 1,000, the second-highest pediatric utilization category.
Behavioral Health Workforce Shortage: A Supply Side Falling Further Behind
The workforce data in the report is the other half of the story M&A advisors and payers are reading. Fewer than 10% of behavioral health providers are MD or DO psychiatrists. The majority of the roughly 600,000 billing providers are master’s-level clinicians whose scope of practice does not include prescribing. Allied health providers (nurse practitioners and physician assistants) now account for 34.3% of behavioral health prescription volume, up from 20.7% in 2018, and have surpassed psychiatrists to become the most common prescriber type.
By 2038, demand is projected to exceed supply by 36,780 FTEs in adult psychiatry and 99,780 FTEs in mental health counseling. Only psychiatric nurse practitioners are tracking toward meeting demand. Even with residency growth from 1,556 positions in 2018 to 2,388 in 2025, the match rate has stayed near 100%, which the report reads as evidence that supply is artificially constrained by the number of funded positions rather than by applicant interest. Burnout data compounds the structural picture: 83% of behavioral health providers reported burnout in 2023, with therapists reporting the highest mental health fatigue rate of any specialty at 77% and most commonly citing low compensation as the driver.
Mental Health Parity Rule Enforcement Discontinued as Federal Budget Retrenches
The Trilliant report documents something that deserves more attention in behavioral health coverage than it has received: the Trump Administration has discontinued enforcement of the Mental Health Parity Rule, which the report says increases financial and administrative barriers independent of any budget action. Separately, the President’s FY 2027 Budget Request proposes to reduce NIH funding by $5 billion and to consolidate HRSA, SAMHSA, CDC, and OASH into a new Administration for a Healthy America. For behavioral health providers already operating inside the supply constraints above, the combined effect is fewer federal enforcement levers at exactly the moment payer-side utilization scrutiny is intensifying.
Cost, meanwhile, remains the single largest barrier to care. The report finds that 65.2% of adults with unmet mental health needs cite cost, and that commercial psychotherapy rates vary by as much as 7x for the same CPT code. The median UnitedHealthcare rate for CPT 90837 (individual psychotherapy) is $147, with a range of $78 to $542. That variance, applied at scale, is what Oakes means when she says the industry needs to reorient around a common standard: value for money.
Behavioral Health M&A Activity Reflects the Demand-Supply Mismatch
The M&A read-through is direct. The sector recorded 167 behavioral health transactions in 2025, led by 111 mental health deals, including Spring Health’s planned acquisition of Alma (expected to close in Q2 2026) and Universal Health Services’ announced acquisition of Talkspace in March 2026. That activity sits on top of the consolidation Acuity has tracked across autism services, where a recent study found that private equity acquired nearly 600 autism therapy sites in a decade and the ten largest ABA providers now anchor much of the sector’s clinical footprint.
What the report makes newly measurable is the pace at which that consolidation is happening against a backdrop of unmet demand. Workforce shortages are present across the behavioral health workforce generally, and the payer scrutiny the Trilliant report predicts will intensify is already visible in the state Medicaid audit and rate-cut cycle autism providers are navigating.
Emerging Treatments, Prescription Digital Therapeutics, and Behavioral Telehealth
The report devotes meaningful space to emerging treatment modalities, including ketamine, psilocybin, and MDMA for treatment-resistant conditions, and to FDA-regulated prescription digital therapeutics (PDTs) for anxiety, depression, PTSD, and substance use disorders. The December 2025 FDA approval of Flow Neuroscience’s at-home brain stimulation device for depression marked the first at-home non-invasive neuromodulation device approved by the agency. Telehealth now accounts for 65.6% of behavioral health visits, up from 18.4% in 2018.
What the Trilliant Data Means for Behavioral Health Operators in 2026
For operators, the Trilliant data is less a set of new findings than an empirical scaffolding for pressures the industry has been absorbing in fragments. Demand is rising across nearly every diagnosis category. Supply is constrained at the provider level by training capacity, reimbursement, and burnout. Federal parity enforcement has stopped. Payer-side scrutiny of high-growth service lines, most visibly ABA, is increasing. Valuations are being set against that combination. The report’s call for value-based reorientation is the structural argument that follows. Whether operators position against it or with it will shape the next two years of the behavioral health M&A cycle.
