Using NJ FamilyCare and Private Insurance Together for ABA: Coordination of Benefits

In short: Coordination of benefits (COB) lets families use NJ FamilyCare alongside private insurance for ABA therapy, but the primary and secondary payer rules depend on each policy. Typically, private insurance pays first, then NJ FamilyCare covers remaining costs like copays or deductibles. Families must report dual coverage and work with providers to ensure claims process correctly.
Key takeaways
- Coordination of benefits allows NJ FamilyCare to act as secondary insurance after your private plan, reducing out-of-pocket costs.
- Your private insurance is usually primary; NJ FamilyCare pays for what's left, like copays or deductibles.
- You must report both coverages to NJ FamilyCare and your provider to avoid claim denials.
- ABA therapy is a covered benefit under many NJ FamilyCare plans (like Horizon NJ Health) when medically necessary.
What Is Coordination of Benefits for NJ FamilyCare and Private Insurance?
Coordination of benefits (COB) is the process that determines which health plan pays first-and how much the second plan pays-when a person has more than one insurance policy. For families in New Jersey seeking Applied Behavior Analysis (ABA) therapy for a child with autism, managing two plans like NJ FamilyCare (New Jersey's Medicaid program) and a private employer-based or marketplace insurance can reduce costs and expand access to care.
COB rules follow federal guidelines and state-specific regulations. The primary goal is to prevent duplicate payments and ensure that total benefits do not exceed 100% of the service cost. When done right, families can use both plans to cover ABA therapy with minimal or no out-of-pocket expense.

Why Combining NJ FamilyCare and Private Insurance Makes Sense for ABA Therapy
ABA therapy is a critical, evidence-based intervention for individuals with autism, but it can be expensive-often ranging from $50 to $150 per hour. Private insurance plans in New Jersey are required to cover ABA for medically necessary autism treatment under the state's autism insurance mandate. However, these plans may have deductibles, copays, coinsurance, or session limits.
NJ FamilyCare, as a second payer, can pick up those costs. For example, if your private plan has a $500 deductible or a $20 copay per session, NJ FamilyCare may cover those amounts after the private plan processes its portion. This can lead to zero out-of-pocket expenses for families who meet eligibility criteria.
How Coordination of Benefits Works: The Basic Rules
Primary vs. Secondary Payer
Generally, the primary payer is the insurance plan that pays first. According to NJ FamilyCare and federal COB rules, if a child has both private insurance and NJ FamilyCare, the private insurance is considered primary. NJ FamilyCare is the secondary payer, covering any remaining allowed charges-up to the plan's maximum.
Exceptions may apply if the private plan is a high-deductible health plan or has specific coordination language. Always check with both insurers to confirm the order.
What NJ FamilyCare Covers as Secondary
As secondary, NJ FamilyCare may pay for:
- Deductibles (the amount you owe before private insurance starts paying)
- Copays (fixed per-visit fees)
- Coinsurance (percentage of costs you pay after deductible)
- Services denied or not covered by private insurance (if those services are covered under NJ FamilyCare)
Note that NJ FamilyCare will not pay more than the amount that would have been paid if it were the only insurance.

Step-by-Step: How to Coordinate NJ FamilyCare and Private Insurance for ABA
Step 1: Check Your Private Insurance Policy
Review your private insurance plan's benefits for ABA therapy. Look for coverage limits, referral requirements, and out-of-pocket costs. Contact the insurance customer service to ask about coordination of benefits with Medicaid-some plans have specific rules.
Step 2: Enroll in NJ FamilyCare and Report Dual Coverage
If your child is eligible for NJ FamilyCare (based on income or disability), you must enroll. During application, disclose any other insurance. After enrollment, send a notice of other coverage to NJ FamilyCare. This can be done through your county's Board of Social Services or online via NJFamilyCare.
Step 3: Inform Your ABA Provider
Share both insurance cards with your ABA provider's billing team. They need to submit claims to the primary payer first, then to NJ FamilyCare. Many providers have experience with COB and can guide you.
Step 4: Obtain Prior Authorizations
Both plans may require prior authorization for ABA therapy. Your BCBA (Board Certified Behavior Analyst) must submit treatment plans-often including a diagnosis, functional assessment, and goals. Start this process early to avoid delays.
Step 5: Monitor Claims and Follow Up
After sessions, check your Explanation of Benefits (EOB) from both insurers. Ensure the primary plan paid its share, and the secondary plan processed the rest. If a claim is denied, work with your provider to fix the issue, such as providing correct billing codes or documentation.
Common Challenges and Mistakes to Avoid
- Failure to report dual coverage: Not telling NJ FamilyCare about private insurance can lead to overpayment and potential clawbacks.
- Assuming both plans cover 100%: NJ FamilyCare only pays up to its allowed amount. Any balance beyond that is not covered.
- Ignoring network requirements: Some NJ FamilyCare plans (like Horizon NJ Health or Aetna Better Health) have provider networks. Ensure your ABA provider is in-network for both plans.
- Delaying prior authorization: ABA authorizations can take weeks. Start as soon as you have a treatment plan.
- Not coordinating with your provider: The provider's billing department must understand COB. If they don't, ask to speak with a supervisor.

Special Considerations for ABA Therapy and NJ FamilyCare
ABA Coverage Under NJ FamilyCare
NJ FamilyCare covers ABA therapy for children under 21 when deemed medically necessary. Services include assessment, behavior intervention, and parent training, provided by a BCBA or supervised RBT. You must get a referral from a doctor and prior authorization from NJ FamilyCare's managed care organization (MCO).
Managed Care Organizations (MCOs)
Most NJ FamilyCare members are enrolled in an MCO like Horizon NJ Health, Aetna Better Health, or WellCare. Each MCO has its own rules for COB, prior authorization, and provider networks. Contact your MCO directly for guidance on how to coordinate with private insurance.
