ABA demand is strong, but economics are tightening and scrutiny is rising. See what four years of data show about execution across the care journey.
Demand for autism and intellectual and developmental disabilities (IDD) care remains strong. But beneath the growth, the market is changing, and strong demand doesn’t make it easier to operate.
Reimbursement rates aren’t always keeping pace with the cost and complexity of care. Audit activity and documentation scrutiny is rising. Care delivery is becoming more complex while workforce instability constrains capacity. And payers and families increasingly expect clearer evidence of outcomes and quality.
Those pressures don’t land in one place. They show up at every stage of the care journey: plan treatment, deliver care, measure quality, and grow revenue.
How We Evaluated the Shift: Four Years, 699 Organizations
CentralReach analyzed four years of continuous data from 699 provider organizations, including:
$24.3
billion in insurance
$167
million claims
$424
million service hours
> 417,000
providers
> 613,000
clients
Taken together, the data show where the pressure is building at each stage, and where top performers are pulling ahead.
1. Plan Treatment: complexity starts before the first session
ABA organizations are managing more learners, clinicians, locations, and models of care than ever. Clinic-based delivery is now the most common service location, and multidisciplinary care is growing as organizations add services to meet more holistic needs.
Every treatment plan has to become an authorization, and every authorized hour has to become a scheduled session with the right clinician. That means scheduling, authorization management, documentation, reporting, and billing can’t function as separate workflows. Each depends on accurate information moving across teams and systems. When it doesn’t, clinically appropriate authorized hours go unused, which means missed care and unrealized revenue.
Complexity isn’t going away. The strategic question is whether an organization’s technology adds to that burden or helps absorb it.
2. Deliver Care: documentation is the fault line
Scrutiny of ABA billing intensified in 2026. CentralReach’s revenue cycle management team reported an unprecedented increase in audits among its customers. At the federal level, the HHS Office of Inspector General completed additional state audits in Maine and Colorado as part of its ongoing review of Medicaid payments for ABA and related services.
In each audit, all 100 sampled enrollee-months contained at least one claim line classified as improper or potentially improper. Documentation was a recurring issue, with findings citing insufficient session notes, missing signatures, and unclear evidence of billable time.
An improper payment isn’t necessarily evidence of fraud. It can result from documentation, billing, credentialing, or other compliance gaps. But the financial consequences can still be serious: even clinically appropriate care may face denials, payment delays, or recoupment if the documentation doesn’t clearly show the service met payer requirements. Providers that stay audit-ready will be the ones that document correctly the first time.
Delivery also depends on people. Staffing gaps limit capacity and disrupt continuity of care, and the gains from improving retention are significant: across the organizations in our data, a 10-percentage-point improvement in turnover would mean approximately 10,000 more people staying with their organizations. Caregiver training is another opportunity.
3. Measure Quality: the performance gap is where the proof lives
Payers and families increasingly expect clear evidence of outcomes and quality. The market data contains an encouraging signal: providers facing similar external pressures are achieving vastly different results. Authorization utilization is slowly improving across provider segments, but the gap remains substantial.
