Your Child's ABA Insurance Coverage: Terms Explained

Insurance letters can make a straightforward question (“what will this cost and when can we start?”) feel impossible. This is a plain-English glossary for the terms families most often hear while arranging ABA. Your plan documents and EOB remain the final word for your coverage.

The cost-sharing terms

Term	Plain-English meaning	Question to ask about ABA
Deductible	The amount you may pay for covered services before the plan starts paying its share, depending on the plan rules.	Does this service apply to the individual or family deductible? How much has been met this plan year?
Copay	A fixed amount a plan may require for a covered service.	Is there a copay for the assessment, each therapy session, or both?
Coinsurance	The percentage of an allowed charge that you may pay after the deductible, if the plan uses coinsurance.	What percentage applies after the deductible, and is the provider in network?
Out-of-pocket maximum	The most you generally pay for covered, in-network benefits in a plan year, subject to the plan’s terms.	What spending counts toward it, and how much has already been credited?
Allowed amount	The amount the plan recognizes for a covered service, often used to calculate the plan and member share.	Is the estimate based on the plan’s allowed amount or an unverified billed charge?

The legal ceiling on your out-of-pocket maximum. Most non-grandfathered plans cannot set an in-network out-of-pocket maximum above the federal limit. For 2026 that limit is $10,600 for one person and $21,200 for a family. For plan years starting in 2027 it rises to $12,000 and $24,000 (CMS, January 2026). Your plan’s own maximum is often lower. HSA-eligible high-deductible plans have a lower cap: $8,700 for one person and $17,400 for a family in 2027. Our deductibles and HSA guide explains how that plays out across a year of ABA.

The HealthCare.gov glossary explains these terms in more detail. It is a useful neutral reference when a plan representative uses a word differently from the one you expected.

The paperwork and approval terms

Term	What it usually means	What to save
Benefits verification	A check of what the plan says about coverage, network, and member cost sharing.	Date, representative, and call reference number.
Prior authorization	A plan review before a service. It may also be called preauthorization, prior approval, or precertification.	The approval or request number, decision letter, and effective dates.
Assessment authorization	Approval, when required, for the initial clinical assessment.	Whether the assessment is authorized and any date limits.
Treatment authorization	Approval, when required, for the proposed treatment plan or a period of services.	The approved setting, date range, and any stated limits.
Reauthorization	A later review if a plan requires another approval period.	The current end date and when the provider submitted the next request.
EOB (Explanation of Benefits)	A statement explaining how the plan processed a claim. It is not automatically a bill.	The EOB alongside the provider invoice, before paying a disputed amount.

Reauthorization is where hours most often change. Our guide to ABA reauthorization explains what the plan reviews and what you can do before the next request goes in.

Prior authorization can be important, but it is not a promise of payment. HealthCare.gov specifically cautions that preauthorization does not guarantee coverage of the cost. Ask the plan what is covered, what it needs, and what amount remains your responsibility.

How to read an EOB without panicking

Look for four things:

1. The date of service and provider. Make sure they are correct.
2. The amount billed, allowed, paid by the plan, and assigned to you.
3. Any reason code or note explaining a reduction or denial.
4. Whether the document says you owe a provider, or simply explains how the plan processed the claim.

Compare the EOB with any invoice from the provider. If they do not match, pause before paying and ask both the provider and insurer to explain the difference. A denied claim can be a documentation or network issue, not necessarily the final coverage answer.

The questions worth asking on every benefits call

• Is this provider in network for ABA or adaptive-behavior services?
• Is authorization required for the assessment, treatment, or both?
• Which costs apply: deductible, copay, coinsurance, and out-of-pocket maximum?
• Does the plan use an approval period or renewal date?
• Can you give me a written benefit summary or call reference number?

If a plan says no to a treatment or claim, save the notice. Washington residents can review the Office of the Insurance Commissioner’s health-insurance denial and appeal guidance, then use our ABA denial and appeal checklist.
