Getting Autism Therapy Covered by Insurance in Ohio

What Ohio law requires

Ohio's autism insurance mandate lives in two parallel sections of the Revised Code. Section 3923.84 covers sickness and accident insurers; section 1751.84 covers health insuring corporations, which is what Ohio calls HMOs. They say the same thing. Both were created by House Bill 463 and took effect on 6 April 2017, and both were last amended effective 20 March 2025.

The core duty has no age limit. A plan the law reaches must cover the screening, diagnosis and treatment of autism spectrum disorder, and it cannot terminate, refuse or refuse to renew someone's coverage solely because they have been diagnosed with autism or treated for it.

The guaranteed amounts stop at 14. This is the part families are most often told wrongly, and it changes what you should expect from a renewal. The statute sets out minimum benefits for an insured under the age of fourteen:

• 20 hours per week of clinical therapeutic intervention. This is the category ABA falls under — the statute defines clinical therapeutic intervention as evidence-supported therapies “including, but not limited to, applied behavioral analysis”.
• 20 visits per year of speech and language therapy, and 20 visits per year of occupational therapy, each performed by a licensed therapist.
• 30 visits per year of outpatient mental or behavioral health services, from a licensed psychologist, a licensed physician including a psychiatrist, or a clinical nurse specialist or certified nurse practitioner.

These are floors, not ceilings — the law says benefits shall cover these amounts at minimum, and a plan is free to cover more. In practice many insurers authorize to the floor and no further, so the floor is worth knowing by heart.

At 14 and older the plan must still cover autism treatment under the general duty above, but the statute stops naming amounts. Coverage then runs on the plan's own medical-necessity rules, which is a weaker position to argue from and the reason a teenager's authorization can shrink without the plan breaking any law.

Dollar limits are a parity rule, not an absence. Autism coverage cannot carry dollar limits, deductibles or coinsurance less favorable than those applying to substantially all medical and surgical benefits under the same policy. That is a comparison test. If your plan imposes a limit, the question is not whether a limit exists but whether the same limit applies to medical and surgical care generally.

Prior authorization is in the statute. Ohio law makes this coverage contingent on two things, and both are easy to trip over. The first is that the person obtains prior authorization. The second is that the services are prescribed or ordered by a psychologist trained in autism, a developmental pediatrician, or a clinical nurse specialist or certified nurse practitioner specializing in pediatric health. An order from a general pediatrician is not on that list, so ask who is signing before the request goes in.

Who may deliver ABA. Clinical therapeutic intervention must be provided by, or under the supervision of, a Certified Ohio Behavior Analyst as defined in Revised Code 4783.01, an Ohio-licensed psychologist, or someone licensed in Ohio to practice professional counseling, social work, or marriage and family therapy. Certified Ohio Behavior Analyst is a state credential and is the term the statute uses. BCBA is a national board certification, and holding one is not by itself what the Ohio statute asks for.

Which plans are not covered. Self-funded employer plans are generally pre-empted by federal ERISA law. Beyond that, the sections exclude nongrandfathered plans in the individual and small group markets, which are governed by the ACA essential health benefits benchmark instead, along with Medicare supplement, accident-only, specified disease, hospital indemnity, disability income, long-term care and other limited benefit policies. Confirm which category your plan is in before filing a complaint that rests on the mandate.

School services are separate. The statute says explicitly that it does not affect any obligation to provide services under an individualized family service plan, an individualized education program, or an individualized service plan. An insurer cannot point at the school district to avoid covering treatment, and a district cannot point at your insurance to avoid providing services on the IEP.

Prior authorization in Ohio

Prior authorization is not optional here — the statute conditions coverage on it. Your provider or the prescribing clinician submits the request. Documents to prepare:

• The autism diagnosis report, with DSM-5 criteria documented
• A letter of medical necessity from a prescriber the statute recognizes — a developmental pediatrician, a psychologist trained in autism, or a pediatric clinical nurse specialist or nurse practitioner
• The treatment plan with recommended weekly hours
• The treating provider's NPI and Ohio credential details
• Any prior authorization forms specific to your insurer

Get the approval in writing before the first session, and confirm the authorized hours, the number of sessions and the expiry date. Set a calendar reminder for renewal a month ahead.

On re-authorization: outside inpatient care, Ohio law lets the insurer review the treatment plan annually. More frequent review requires agreement between the insurer and your child's treating physician, nurse specialist, nurse practitioner or psychologist, and that agreement applies only to your child rather than to every patient the clinician treats. The insurer must also cover the cost of obtaining any review or treatment plan. If you are being asked to re-justify services every few months at your own expense, those are the provisions to quote.

Appeals

If your Ohio insurer denies autism coverage or prior authorization:

1. Request the denial reason in writing. Insurers must give a specific reason. You need it in order to answer it.
2. File a written internal appeal and have the prescribing clinician write a letter addressing the stated denial reason directly. Federal rules give you at least 180 days from the denial notice to start an internal appeal, so do not let anyone tell you the window is a month.
3. Request external review once the internal appeal is exhausted. You have 180 days after the final adverse determination to ask. A standard external review decision should take no more than 30 days, and an urgent one no more than 72 hours — that 30 days is the decision turnaround, not your deadline to file.
4. Contact the Ohio Department of Insurance at 800-686-1526 if you believe the mandate is being violated. The department runs a consumer toolkit specifically for appealing health coverage denials.

Ohio Medicaid

Ohio Medicaid covers ABA for children and young people under 21 through its managed care organizations. This runs on a different footing from the private mandate: federal EPSDT rules require Medicaid to cover medically necessary treatment for under-21s, so the under-14 minimums described above are not the ceiling here. If your child is on Medicaid managed care, prior authorization goes through the managed care plan.

Enrollment: apply through benefits.ohio.gov or your county Job and Family Services office. Children with disabilities may qualify through SSI-linked Medicaid regardless of household income.

Coordinating both: if your child has private insurance and Medicaid, the private plan is billed first and Medicaid picks up what remains. This is worth setting up even when the private plan covers most of the cost, because it is what absorbs the copays and the hours that fall past the private plan's authorization.
