How ABA Coverage Works in South Carolina

South Carolina has a state autism insurance mandate. That mandate requires state-regulated health plans to cover medically necessary ABA therapy. But it only applies to fully insured plans, which are plans where the employer buys coverage from an insurance company.

If your employer self-funds its health plan, the state mandate does not apply. Self-funded plans are governed by federal law, ERISA, and they are not bound by state mandates. Many self-funded plans still cover ABA, but they set their own rules.

This is why two families working for the same employer can get different answers. One might have a fully insured plan, the other a self-funded one. The coverage decision depends on which type you have.

Ask These Questions Before You Call an Agency

Before you call an ABA agency, find out exactly what your plan covers. Call the number on your insurance card and ask these questions:

Is my plan fully insured or self-funded?

Does my plan cover ABA therapy for autism?

Are there any limits on the number of visits or hours per year?

Do I need a referral or prior authorization?

What is my deductible and out-of-pocket maximum for ABA?

Are there in-network ABA providers I must use?

Ask for the name of your plan type and the specific benefits for autism treatment.
Ask for a written summary of your ABA coverage, including any limits.
Ask about the prior authorization process and what documents you need to submit.

The Prior Authorization Process

Most plans require prior authorization before ABA therapy starts. That means your provider must submit a treatment plan to your insurer for approval before you begin.

The treatment plan usually includes a diagnostic evaluation, a treatment plan with goals, and a recommended number of hours per week. Your ABA provider will handle most of this, but you need to be ready to provide your insurance information and any required referrals.

Ask your insurer how long prior authorization takes. Some plans respond in a few days, others take a few weeks. If you are waiting, follow up regularly and keep notes of who you spoke to and when.

What to Do If Your Claim Is Denied

If your claim is denied, you have the right to appeal. Start by reading the denial letter carefully. It will explain the reason and the deadline for filing an appeal.

You can file an internal appeal with your insurance company. If they deny that, you can request an external review by an independent third party. In South Carolina, the Department of Insurance handles complaints and can help if you feel your insurer is not following the rules.

Keep copies of all paperwork, including the denial letter, your treatment plan, and any correspondence. If you need help, your ABA provider may have a billing specialist who can assist with appeals.

Medicaid and Healthy Connections

If your family qualifies for Medicaid, Healthy Connections is the program that covers medically necessary ABA for children under 21. Medicaid covers ABA through the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit.

Your child must have a diagnosis of autism and a doctor's order for ABA. You will need to choose a Medicaid managed care plan, and the plan name is on your member card.

If you are not sure if you qualify, apply through the South Carolina Department of Health and Human Services. You can also contact your local Medicaid office for help with the application.

Find ABA Providers in Your Area

Common questions

Does South Carolina law require insurance to cover ABA therapy?

Yes, but only for fully insured plans. The state mandate applies to plans that are regulated by the state, which are typically individual and small group plans. Large employer plans that are self-funded are exempt under federal ERISA law.

My employer's plan is self-funded. Does that mean ABA is not covered?

Not necessarily. Many self-funded plans choose to cover ABA even though they are not required to. You need to check your specific plan documents or call your benefits administrator to see if ABA is included.

What is the maximum age for ABA coverage in South Carolina?

That depends on your plan. The state mandate has an age limit, but it changes and varies by plan. Ask your insurer directly: 'What is the age limit for ABA therapy coverage under my plan?'

How do I know if my plan is fully insured or self-funded?

Call the customer service number on your insurance card and ask. You can also ask your HR department. They should be able to tell you the type of plan you have.

Does Medicaid cover ABA therapy in South Carolina?

Yes, Medicaid covers medically necessary ABA for children under 21 through the EPSDT benefit. You need a diagnosis of autism and a doctor's order. Your Medicaid plan, which is named on your member card, will manage the coverage.

What if my insurance denies ABA therapy?

You have the right to appeal. Start with an internal appeal to your insurance company. If that is denied, you can request an external review. The South Carolina Department of Insurance can also help if you believe your insurer is not following the law.
