A Parent’s and Provider’s Field Guide to Handling ABA Network Inadequacy

The Plan Still Owes the Care

The autism therapy shortage is well documented. By one 2025 estimate, only 12 of the country’s 3,143 counties have enough providers to meet the distance standards CMS uses to judge network adequacy, and a small-sample October 2025 federal inspector general review found many Medicaid and Medicare Advantage plans had limited behavioral health networks that included inactive “ghost” providers. What gets less attention is what a family or a provider can actually do about it.

The starting point is a rule most families never hear about. Under federal Medicaid managed care regulations, if a plan’s network cannot provide a covered service to a particular enrollee, the plan must cover that service out of network, and at no greater cost to the family than an in-network visit, for as long as the network cannot provide it. The obligation does not disappear when the network runs out of providers; it moves out-of-network.

Commercial plans work differently, but they offer parallel tools, and specifics vary by state and plan. The moves below are the ones that reliably give parents and providers leverage.

What Parents Can Do

Families have more room to push than a waitlist suggests. Used together, the steps below shift the burden back onto the plan.

Document the search. Keep a written record of every in-network provider contacted, the quoted wait time, and every denial, including dates. This paper trail is what supports an out-of-network request, an appeal, or a complaint later. Insurers run their own provider search when they get such a request, so the specifics matter.

Ask for care at the in-network price. Families can call the plan and request out-of-network coverage through a single case agreement or network gap exception, a contract that lets a child stay with an out-of-network provider at in-network cost. Billing specialists say these are most often approved when in-network providers are unavailable, too far away, or backed up with long waits, or when switching providers would set a child back. For Medicaid enrollees, the law generally requires the plan to cover the service out of network at in-network cost when its network cannot deliver it, even if the plan will not contract with the specific provider a family prefers.

Appeal every denial, then go external. A denial is the start of a process, not the end of it. After the plan’s internal appeal, families can request an external review by an independent review organization, arranged through the state insurance department, at little or no cost, since any fee is capped at $25. Standard external reviews are decided within 45 days, and expedited reviews within 72 hours when a delay would endanger the child.

Use EPSDT if the child is on Medicaid. Medicaid’s Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit entitles enrollees under 21 to any service that is medically necessary to treat a diagnosed condition, whether or not the state separately lists it. All 50 states now cover ABA through Medicaid, according to Autism Speaks, so a medical-necessity denial for an eligible child is worth challenging on EPSDT grounds.

Invoke the directory-accuracy rules. If a family relied on the plan’s directory and booked a provider the directory wrongly listed as in-network, the No Surprises Act generally caps their cost at the in-network amount. Plans must verify directory accuracy at least every 90 days. However, a 2025 study found 40 percent of listings were still wrong after roughly 540 days, so families should save a copy of the directory entry they relied on.

File a parity complaint. The Mental Health Parity and Addiction Equity Act (MHPAEA) bars plans from treating behavioral health more restrictively than medical or surgical care. A family that sees tighter limits on ABA than on comparable medical services can file a complaint with the U.S. Department of Labor’s Employee Benefits Security Administration at 1-866-444-3272 for an employer plan, or with the state insurance commissioner for a fully insured plan.

Escalate to the state. Medicaid families can request a state fair hearing after exhausting the plan’s internal appeal, and many states run a Medicaid managed care ombudsperson, alongside the state insurance regulator, which handles access complaints. Regulators track these complaints, and they are part of how a state learns its networks are failing.

What Providers Can Do

Providers sit on the other side of the same gap, and several of the same tools work in their hands.

Set up single case agreements. When a plan’s network is full but a family needs care, an out-of-network provider can negotiate a single case agreement to treat the child at a set rate. Requesting it alongside the initial assessment authorization, with documentation of why in-network options fall short, improves the odds.

Keep your directory listing clean. Ghost listings, providers shown as available who are not, were flagged in the federal review as part of what makes thin networks look fuller than they are. Providers should confirm their status with every plan and send corrections promptly, since the No Surprises Act requires plans to post directory changes within about two business days of receiving them.

Use telehealth to extend reach. Telehealth is one of the few near-term options for serving families who cannot reach a clinic. A New York Medicaid evidence review in July 2025 found telehealth parent-coaching performed comparably to in-person care in the one head-to-head trial it examined, and CASP has published telehealth practice parameters for delivering ABA safely in the home.

Document the gap, and back families up. A clinical letter that spells out medical necessity, the data behind it, and the absence of a timely in-network alternative is often what wins an out-of-network approval or an appeal. A provider who supplies that record turns a family’s request into a documented case the plan has to answer.

File network adequacy complaints. Providers can report inadequate networks and unreasonable wait times to the state Medicaid agency or insurance department. Those complaints feed the same oversight that new federal access rules are trying to strengthen.

Weigh joining the network. Credentialing into a plan entirely removes the out-of-network hurdle for families. Providers can press on rates as a condition, since low payments are one reason networks remain thin.

None of these tools is a guarantee, and each depends on the specifics of a family’s state and plan. They also put the work on the people with the least time to spare, the parents and clinicians already stretched by the shortage. Under the CMS 2024 Medicaid managed care access rule, states are not required to conduct their first independent secret-shopper surveys of network accuracy until the rating period beginning July 10, 2028. Until then, the families and providers who know these rules are the ones most likely to get care through the gap.
