Applied Behavior Analysis (“ABA”) providers in New Jersey are operating in a markedly different environment than they were just a few years ago. Regulators and payors have begun actively auditing providers, and the pressure is coming from several directions at once: a broad federal crackdown on Medicaid program integrity, increasing scrutiny from managed care organizations (“MCOs”) and insurers, ABA-specific audit activity by the U.S. Department of Health and Human Services, Office of Inspector General (“HHS-OIG”), and a recently implemented New Jersey regulatory framework.

For many providers, the immediate risk is not a fraud prosecution; it is a payor demand for a refund years after services were rendered because the documentation, credentialing, supervision, or billing file does not support the claim in the manner an auditor expects. For that reason, the issue is not merely compliance in the abstract; it is payment protection.

Federal Government Scrutiny of Reimbursement of ABA Services

Any discussion of ABA enforcement must begin with the broader federal Medicaid landscape. HHS-OIG has made ABA a recurring Medicaid audit priority and states that federal and state agencies have identified “questionable billing patterns” by some ABA providers and payments to providers for “unallowable services.” HHS-OIG’s current work plan makes clear that it is continuing to audit whether state Medicaid ABA payments complied with federal and state requirements.

That scrutiny is not theoretical. HHS-OIG has already issued ABA-related audit findings in multiple states, and those findings are specific enough to serve as a roadmap for providers regarding the focus areas for regulators. In Colorado, for example, HHS-OIG found at least $77.8 million in improper fee-for-service Medicaid ABA payments and specifically recommended that the state provide additional guidance to ABA facilities on documenting ABA services, including services necessary to support CPT code 97155, signature requirements, and the information needed in session notes; billing ABA, including what counts as billable ABA time; and credentialing requirements for ABA providers. HHS-OIG also recommended statewide post-payment review to educate providers and recover noncompliant payments. Indiana and Maine produced similar themes, with HHS-OIG emphasizing documentation deficiencies, signature issues, provider credentials, and the need for stronger post-payment review and provider guidance.

New Jersey is already part of that federal review effort. HHS-OIG’s active ABA audit series includes Project OAS-25-02-019, which was announced on November 12, 2024, and remains one of three active projects in the series. HHS-OIG’s public work plan does not identify the project title or state while the project remains pending, but provider correspondence confirms that this project currently includes an audit of Medicaid ABA services in New Jersey. According to that correspondence, the stated objective is to determine whether the New Jersey Department of Human Services ensured that its MCOs complied with federal and state requirements for Medicaid ABA services during the period from July 1, 2022, through June 30, 2024.

That distinction matters. Although the audit is formally directed at the State agency and the MCOs, providers are still very much in the crosshairs because HHS-OIG is using sampled provider claims and provider records to test whether the larger Medicaid system functioned properly. In practice, that means a provider may be drawn into a federal audit that is not nominally “about” the provider and still be required to produce records that could reveal deficiencies in documentation, supervision, credentialing, authorization support, payroll support, or billing practices.

For many ABA providers, the practical reality is that they are operating within a layered Medicaid system involving state oversight, managed care authorization, and federal review. When HHS-OIG audits that system, individual providers can be pulled directly into the process because their claims and records are what regulators use to test whether the larger system functioned properly.

The key point is that federal regulators are no longer looking only for obvious phantom billing; they are also asking whether a provider can prove, in a detailed and auditable way, that the right service was rendered by the right person, at the right time, under the appropriate authorization, with the appropriate documentation and supervision.

New Jersey’s ABA Framework is Relatively New, and Oversight Has Been Catching Up

What makes New Jersey especially challenging is that this heightened enforcement is landing in a space where the legal and administrative framework has been developing quickly over the last several years.

On the licensure side, New Jersey’s State Board of Applied Behavior Analyst Examiners (“Board”) finalized its regulations on May 6, 2024, less than two years ago. State materials issued later in 2024 reflect that the Board had only recently opened applications for licensed behavior analysts and licensed assistant behavior analysts. That is a relatively recent development for a field that is now facing aggressive documentation and payment scrutiny regarding the credentialing of its providers.

On the Medicaid and provider-operations side, the framework is also heavily administrative. New Jersey Medicaid is administered by the Division of Medical Assistance and Health Services (“DMAHS”), and ABA providers must navigate formal enrollment requirements, managed care authorization processes, staffing qualifications, supervision expectations, and detailed billing support obligations. New Jersey Medicaid’s ABA enrollment materials reflect a system that expects providers to maintain significant supporting documentation as a condition of participation and reimbursement.

That does not excuse noncompliance. But it does explain a reality many providers know firsthand: that after a few years of lax oversight, the rules are now being actively enforced, the audits are real, but the guidance, tools, and operational support needed to implement everything cleanly have not always matured at the same pace. Providers have had to navigate licensing changes, Medicaid enrollment requirements, managed care authorization processes, staff qualification rules, and evolving documentation expectations while continuing to deliver services in a high-demand clinical environment.

This is one reason why the risk in New Jersey is not limited to intentional fraud. Many providers face exposure because their internal systems were not designed to withstand the level of retrospective scrutiny now being applied.

The New Jersey Audit Trend is About More Than Traditional Fraud

For providers, the most immediate threat is often not a criminal or civil fraud case. It is a recoupment demand, overpayment finding, or audit result concluding that the file does not support what was billed to the payor.

Recent audits by the New Jersey Office of the State Comptroller(“OSC”) show the same pattern. In an audit report issued on March 18th, 2026, regarding Family Therapy and Consultation Services/United Family Services (“Family Therapy”), OSC found that more than 13 percent of reviewed claims failed to meet Medicaid requirements, citing issues such as missing proof of education for behavioral assistants, missing or inaccurate documentation, and progress note deficiencies. OSC framed these rules as safeguards designed to ensure medically necessary care, proper billing, and protection against fraud, waste, and abuse and recommended that Family Therapy reimburse the Medicaid program for the overpayment amount of $1,076,621.

Likewise, the OSC’s June 2025 audit of Greater New Jersey Creative Counseling (“Greater New Jersey”) found substantial claim failure rates tied to provider documentation and compliance issues and recommended that Greater New Jersey reimburse the Medicaid program the overpayment amount of $2,711,289. These reports and reimbursement recommendations make clear that legitimate providers can face major repayment exposure even where services were actually rendered, if they cannot produce the records needed to support the claim.

The federal document requests in the New Jersey ABA audit show exactly what regulators expect a provider to be able to produce on demand. Based on those requests, regulators are looking not just at whether a session note exists, but at the full claim lifecycle, including:

  1. autism diagnosis and DSM-5 support;
  2. referral for ABA therapy;
  3. prior authorization requests and MCO approvals;
  4. session notes and medical records;
  5. supervision documentation;
  6. credentials and related staff qualification records, including documentation for BCBAs, BCaBAs, RBTs, BTs, and other rendering or supervising personnel, together with proof of education, training, employment, and any other records supporting their qualifications;
  7. criminal background checks;
  8. timesheets and pay records;
  9. parental or guardian consent;
  10. provider rosters and credentialing;
  11. Medicaid enrollment status;
  12. supervision policies and documentation methods;
  13. exclusion-check and background-check policies;
  14. record-storage and retrieval systems;
  15. site-of-service and telehealth practices; and
  16. provider-specific guidance received from the State or MCOs.

In other words, ABA providers are being audited not just as clinicians, but as billing entities, supervisors, employers, and record custodians all at once. That is why the recoupment risk is so heightened: both the federal government and the state of New Jersey are testing whether the organization has a defensible compliance infrastructure, not just whether a patient receives treatment.

How Mandelbaum Barrett PC can help

ABA providers need more than abstract legal advice; they need practical guidance on how to operate in a way that is compliant, defensible, and sustainable, particularly when they are interfacing with Medicaid, MCOs, commercial insurers, and multiple regulators at once. The best time to address these issues is before an auditor or payor identifies them.

Our firm helps ABA providers:

  1. evaluate whether clinicians, staff, and contractors are properly credentialed and documented;
  2. review Medicaid enrollment and qualification files for gaps before an auditor or payor finds them;
  3. assess whether supervision practices and records support the services being billed;
  4. tighten authorization, treatment-plan, progress-note, and billing workflows;
  5. strengthen background-check, exclusion-check, and HR documentation systems;
  6. prepare for insurer, MCO, Medicaid, and HHS-OIG audits;
  7. respond to overpayment allegations, recoupment efforts, and record requests; and
  8. build compliance practices that support both patient care and payment retention.

The goal is not simply to avoid enforcement headlines; it is to help providers continue delivering needed services, bill appropriately for those services, and keep what they are paid when scrutiny comes.

For many providers, the central question is not whether they are acting in good faith. It is whether their systems are strong enough to protect the reimbursement they earn. Providers that invest now in audit-ready compliance practices will be in a much stronger position to continue billing and, just as importantly, to defend those claims later.
