The Development
A recent analysis by Trilliant Health indicates a significant increase in Applied Behavior Analysis (ABA) service utilization across the United States, with overall ABA “visits” skyrocketing by 267% between 2019 and 2024. This substantial growth was observed in both Medicaid and commercial health claims, though with differing rates. Medicaid-covered services experienced a nearly 298% increase, outpacing the 249% rise in commercially covered services. The report highlights that this expansion was driven by factors beyond clinical need, suggesting systemic influences at play.
During the same five-year period, the number of clinicians providing ABA services also saw a dramatic increase, more than doubling by 135%. This growth in provider capacity varied significantly by state; for instance, Wyoming experienced a 32% decrease in providers, while neighboring Nebraska saw an astonishing 761% increase. Individual therapy sessions constituted the vast majority of services, accounting for 85% of all measured claims. Notably, the growth rate for Medicaid patients surged past commercial claims in 2022 and 2023, with Medicaid services increasing 341% in 2023 relative to 2019, compared to 169% for commercial claims in the same year.
Market Impact
The analysis raises critical questions for the ABA industry, particularly concerning whether diagnostic standards are consistently applied and if financial incentives are inadvertently driving inappropriate utilization. The report points to “supply-induced demand,” a well-established phenomenon in healthcare economics where an increase in provider availability can lead to higher service utilization irrespective of underlying patient need. This suggests that the sheer growth in the number of ABA clinicians may have contributed to the surge in demand.
Concerns also center on the “perverse incentives” created by a lack of stringent oversight regarding care quality, claims process rigor, and the absence of fixed industry standards within the current fee-for-service payment model. This structure, which reimburses based on service volume rather than outcomes, can misalign incentives, potentially leading providers to prioritize maximizing billable hours over achieving meaningful improvements in children’s functioning. Without systematic tracking of diagnostic processes or treatment outcomes, states lack the necessary data to determine if increased spending reflects appropriate service expansion or systemic issues like overdiagnosis and unnecessary treatment.
The report warns that runaway costs threaten the viability of service coverage, especially within Medicaid programs. Several states have already taken action to curb spending; Nebraska implemented rate cuts, and Indiana introduced cuts in 2023, later proposing limits such as lifetime-service-hour maximums. Weak oversight of providers is also noted as a potential harm to patients, as it may limit access for those who genuinely need care by diverting finite resources.
What’s Next
To address these challenges, the report’s recommendations largely align with the autism therapy industry’s growing advocacy for a transition to value-based care. Key proposals include mandates for collecting and reporting on care outcomes, comparing care delivery to established norms, and developing better parameters for assessing treatment progress. The goal is to ensure that every child meeting diagnostic criteria for autism can access appropriate, high-quality services from qualified providers, while preventing the diversion of resources to children who might benefit more from alternative interventions or to providers prioritizing billing optimization.
Further recommendations suggest that states consider implementing standardized diagnostic evaluations conducted by clinicians independent of treatment providers. Mandatory reporting of treatment hours relative to established guidelines, increased investment in audits, and case-level investigations of impropriety are also proposed. Crucially, the report advocates for tying reimbursement directly to care outcomes, shifting the focus from volume to the effectiveness of interventions. These steps aim to foster greater accountability and ensure that the significant investment in ABA services translates into tangible benefits for children and families.
