CMS proposes tighter oversight of Medicaid-funded autism ABA therapy

On Tuesday, the Centers for Medicare and Medicaid Services released a guidance package aimed at reshaping how states manage applied behavior analysis, the predominant therapy for autistic children on Medicaid. The document stresses tighter oversight, demanding clearer outcome metrics and cautioning against reliance on telehealth as the main delivery method due to fraud risks. ABA expenditures in Medicaid and CHIP have risen 421% between 2021 and 2025, with reports of both extravagant provider fees and widespread denial of services leading to long waitlists.

Although the toolkit does not carry regulatory force, insiders say states are likely to incorporate many of its recommendations over time. The move reflects growing scrutiny of rapid spending growth and seeks to balance access with accountability. Stakeholders anticipate a gradual shift in how autism care is funded and monitored across the United States.
