Virginia’s new budget sets a 20-hour weekly Medicaid ABA cap and an autism diagnosis rule, softened by EPSDT exceptions and a coming utilization workgroup.
Key Takeaways
- A statutory cap, not just a guideline. Beginning July 1, 2026, Virginia’s budget directs the Department of Medical Assistance Services (DMAS) to impose a cumulative 20-hour weekly limit on Medicaid ABA per recipient, a threshold that until now lived in provider guidance rather than in law. The same language requires a confirmed autism spectrum disorder diagnosis before ABA can be authorized.
- The cap is written to bend. The limit can be exceeded when medical necessity is documented under EPSDT, the federal benefit that entitles Medicaid members under 21 to medically necessary care, which makes this a soft cap rather than a hard ceiling. Children age five and younger also gain a one-year provisional diagnosis pathway while a full evaluation is pursued.
- Virginia is following a national pattern. State Medicaid programs from North Carolina to Indiana to Nebraska have moved to cut ABA rates or cap hours as spending has surged and federal audits have flagged improper payments. Virginia’s own Medicaid forecast shows ABA becoming the largest behavioral health service even as the program faces a multibillion-dollar funding gap.
- The next fights are the SPA and the workgroup. DMAS must file a State Plan Amendment with the federal Centers for Medicare and Medicaid Services, where parity and EPSDT compliance questions could surface, before the changes take full effect. A new DMAS utilization workgroup, with a seat reserved for the Virginia Association for Behavior Analysis (VABA), will shape how the cap, documentation rules, and medical-necessity criteria are actually written.
Virginia became the latest state to tighten Medicaid spending on autism therapy when Gov. Abigail Spanberger signed the Commonwealth’s 2026 to 2028 budget, which was finalized June 29 and takes effect July 1. Tucked into the Medicaid language is a provision, which VABA identifies as Item 291, directing DMAS to cap ABA at 20 cumulative hours per recipient each week and to require an autism spectrum disorder diagnosis before services are authorized. In a member update, VABA’s Public Policy Committee said its effort to strike both the cap and the autism-only requirement during the session fell short.
The association framed the outcome as a fiscal one. The provision originated in the outgoing Youngkin administration’s introduced budget rather than as a new initiative from Spanberger or the current General Assembly, according to VABA, but the arithmetic of Medicaid growth made it difficult to dislodge once negotiations were underway. The governor and lawmakers, the committee wrote, were largely unmoved by the advocacy campaign mounted against it.
The 20-hour figure is not entirely new. A December 2025 DMAS bulletin had already reminded providers that service authorization requests above 20 hours per week required significant documentation and justification, and that clinic-based services needed a documented clinical rationale. What changes on July 1 is the status of that threshold: it moves from contractor guidance into budget language, paired with a statutory autism-diagnosis requirement and instructions for DMAS to run pre- and post-payment reviews with managed care organizations and to collect standardized reporting across them. That review apparatus has already produced contentious clawback disputes in other states.
Crucially, the cap is designed to bend. The budget allows the 20-hour limit to be exceeded “based upon documented medical necessity under” EPSDT, the federal provision that obligates Medicaid to cover medically necessary services for members under 21. That carveout is what separates a soft cap from a hard ceiling, and it mirrors the design other states have used to reconcile hour limits with EPSDT’s broad federal mandate. Nebraska, for instance, lets families receive up to 30 hours a week before additional review is triggered. The argument over those thresholds is part of a broader clinical debate over whether blanket hour levels serve children well.
VABA did secure two amendments it had pressed for. One creates a provisional-diagnosis pathway: children age five and younger may receive a provisional diagnosis for up to one year under a protocol DMAS designates, giving families whose children present with developmental delays a route to ABA while a comprehensive evaluation is pending. The second directs DMAS to convene an ABA benefit utilization workgroup, with VABA holding a seat, to examine expenditure and utilization trends and to recommend ways to control costs while preserving access for those who need the therapy.
Why Virginia Joined a National Wave of ABA Restrictions
Virginia’s move lands in the middle of a national reckoning over Medicaid ABA spending. Nationally, Medicaid spending on the therapy increased roughly 300 percent between 2019 and 2024, according to figures presented to North Carolina lawmakers. Individual states have seen far steeper climbs: North Carolina’s ABA payments are projected to reach about $639 million in fiscal 2026, up more than 400 percent from 2022, while Indiana’s grew from $21 million in 2017 to more than $600 million by 2023.
Those increases have triggered a wave of cost-control measures that Acuity has tracked across the country. Indiana paired rate cuts with a lifetime cap on comprehensive therapy hours and an under-21 restriction. New York imposed a 25 percent cut to its core technician rate. In Georgia, the dominant Medicaid plan moved to reimburse ABA at 80 percent of the state fee schedule. A handful of states, including Oregon, have held their ABA rates steady, a posture that now reads as the exception. Federal scrutiny has compounded the pressure: Office of Inspector General audits have identified improper payments across multiple states.
Virginia’s fiscal backdrop helps explain the appetite for limits. In a November presentation to the Senate Finance and Appropriations Committee, DMAS data showed ABA had quickly become the largest behavioral health service in Medicaid managed care, even as the agency flagged inadequate utilization controls on certain services. The broader Medicaid forecast projects a general fund need of roughly $410 million in fiscal 2026 and about $2.8 billion over the 2026 to 2028 biennium, driven largely by managed care rates and higher utilization. Looming federal Medicaid reductions under the 2025 reconciliation law add to the squeeze.
What the 20-Hour Cap Will and Will Not Touch
For providers and families, the immediate questions are about implementation. The budget exempts behavior therapy delivered by local education agency providers and reimbursed through the fee-for-service school-based Medicaid program, leaving that channel outside the cap. DMAS is authorized to promulgate emergency regulations within 280 days of enactment and to implement the change upon federal approval, even before any full regulatory process concludes, an unusually fast track that gives providers little runway to adjust. Virginia is not the only state rewriting its ABA rules for July 1: South Carolina is overhauling its Medicaid ABA provider manual to tighten telehealth, documentation, and medical-necessity standards the same month.
The autism-only requirement carries its own tension. The budget restricts ABA to recipients with an autism spectrum disorder diagnosis, yet the same legislation directs the new workgroup to evaluate the appropriateness of ABA for children with diagnoses other than autism, a sign that the question is not fully settled. Other states have been tightening the same gate: Alabama spent 2026 sharpening diagnostic authority and provider requirements for its Medicaid ABA benefit. How DMAS squares the diagnostic restriction with the workgroup’s mandate will matter for the caseloads of providers who have long served some children with related developmental conditions.
The SPA Filing and Workgroup Will Decide the Details
The most consequential near-term step is procedural. To change its program rules, DMAS must file a State Plan Amendment with the federal Centers for Medicare and Medicaid Services, which reviews and approves such changes. VABA’s policy committee said it does not expect the agency to reject the filing outright, but noted that rejection remains possible on compliance grounds, citing the Mental Health Parity and Addiction Equity Act and EPSDT requirements. Those are the same federal levers that have shaped ABA disputes in other states, and they give the filing at least some chance of friction before approval.
Much of the rest will be worked out in the utilization workgroup, which the budget requires DMAS to convene with public meetings and opportunities for public input. Its charge is broad: to examine utilization trends by diagnosis acuity, review service-authorization and medical-necessity criteria, evaluate provider qualification and supervision standards, and assess the managed care reporting data the budget now requires. The panel is to include center-based and home-based providers, managed care representatives, Virginia-licensed behavior analysts, and a child or adolescent psychiatrist. For VABA, a seat at that table is the consolation in a session that otherwise went against it, and the venue where the cap’s real contours, including how readily the EPSDT exception is granted, will be drawn.
