Medicaid ABA Billing Fraud: The Session Has to Match the Claim

Medicaid ABA billing fraud involves knowingly false claims about the treatment delivered, the units billed or the qualifications of the person who did the work. A technician may know what happened in the room. A behavior analyst may know what supervision or treatment changes occurred. A billing employee may know which version reached Medicaid. The autism-treatment audits put those connections under scrutiny: the session note, the worker and the payment need to tell the same story.

How ABA Treatment Becomes a Medicaid Claim

Applied behavior analysis is a treatment approach for autism and other developmental disabilities, usually focused on social and communication skills. The HHS Office of Inspector General’s audits examined fee-for-service payments: claims for identified services. This is a provider billing question, with the treatment, person delivering it and supporting documentation behind each claim.

Children’s coverage has a particular foundation. Medicaid’s Early and Periodic Screening, Diagnostic and Treatment benefit requires medically necessary covered categories of health care for people under twenty-one, even when the state’s adult benefit package omits them. ABA billing sits within that obligation to provide treatment.

Billing for treatment nobody delivered takes money meant for the child’s care. The taxpayer pays, and the child still needs the treatment. We start with whether the session happened as billed and who was qualified to deliver it.

What the Medicaid ABA Audits Found

In the Indiana, Wisconsin, Maine and Colorado autism-treatment audits, the HHS Office of Inspector General found at least one improper or potentially improper charge in all 100 sampled months of individual children’s care in each state. We find that repetition striking: every sampled month raised a payment question. In every state examined.

The Indiana audit examined services billed in 2019 and 2020 and estimated at least $56 million in improper payments. The state’s own spending had risen from $14.4 million in 2017 to $101.8 million in 2020.

Wisconsin’s audit examined 2021 and 2022 payments and estimated at least $18.5 million in improper payments. Maine’s review covered 2023 and estimated at least $45.6 million. The Office of Inspector General includes both reviews in its autism-treatment audit series.

The Colorado audit examined 2022 and 2023 payments and estimated at least $77.8 million in improper payments. Its recommendations reached the documentation of treatment, billable time, practitioner credentials and the contractor checking prior authorizations.

Colorado’s Improper and Potentially Improper Payment Estimates

The Colorado audit puts concrete amounts behind the billing problems: the Office of Inspector General recommended a refund of $42,649,438 in federal funds for noncompliant payments. It also asked the state to review an estimated $112,542,978 in federal funds associated with potentially improper payments and return amounts found improper.

The audits identify payments that need answers. A civil whistleblower case connects a false claim to what people inside the provider knew. For someone inside a clinic, that connection starts with the session: what did the claim say, and what does the person who delivered the treatment know about it?

The Session Records Behind ABA Billing

Behavioral health billing depends on the relationship between the service, its units, the practitioner and the requirements for payment. The ABA audits make that relationship unusually concrete. They ask about the person who rendered treatment, the work supporting the code, the detail in the note and the authorization behind the service.

Who Rendered the Treatment?

Wisconsin’s audit identified a payment problem involving CPT code 97153, adaptive behavior treatment by protocol. The Office of Inspector General called for the state to verify who rendered the service and pay according to that person’s specialty level. The distinction reaches the technician’s work and the analyst’s rate.

We see the problem in plain terms: changing the name or specialty on the bill cannot change who treated the child. The clinical employee knows who did the work. The billing employee sees whose identity and specialty the claim used. Connecting those facts can expose a payment based on a different practitioner from the one who delivered the service.

That is why credentials and supervision belong beside the session record. We examine the person’s actual role and qualifications against the state’s requirements for that treatment.

What Changed in the Treatment Protocol?

CPT code 97155 concerns protocol modification with the patient present. The HHS Inspector General asked Wisconsin to require documentation of how issues were resolved or what changed in the treatment protocol or plan of care. Colorado’s recommendations likewise called for guidance about the services needed to support that code.

For a behavior analyst, the question is recognizable: what issue did the session address, and what did the practitioner do about it? A note that identifies the problem, the work and the resulting treatment decision gives the reviewer something specific to compare with the billed service. A code entered in the billing system supplies none of that clinical detail on its own.

Which Units Does the Note Support?

The audits put session-note detail, signatures and billable time together. Indiana and Colorado both received recommendations for clearer guidance about what counts as billable ABA time and how providers must document it. The number of units on the claim needs support in the treatment record.

A technician knows what happened during the session. A biller sees the units entered for payment. We work through that connection with the person who knows the work: does the note describe the time spent treating the child, and does the bill match it? If a claim describes work you know never happened, you can explain what the paperwork conceals.

What Supported the Authorization?

Prior authorization reaches the diagnostic evaluation and treatment referral behind the services. The Office of Inspector General asked both Indiana and Colorado to review how their authorization contractors verified those requirements. The authorization decision, the treatment documentation and the claim belong in the same examination.

Someone reviewing requests may know what the contractor checked. Someone providing treatment may know what occurred afterward. We connect those views to the service Medicaid paid for.

What Triggers a Medicaid Fraud Investigation?

Claims analysis, audits and referrals can bring provider billing to investigators’ attention. In ABA, the Inspector General’s audit series shows how a review moves from paid claims into the records supporting treatment and practitioner qualifications.

Applying Business Intelligence Concepts to Medicaid Claim Fraud Detection, published in the Journal of Information Systems Applied Research in 2012, explains the handoff from unusual billing to expert review. Statistical methods can identify outliers for investigation, after which expertise is needed to determine whether the transactions are valid. The study used Nevada medical-supply claims. Its useful lesson for ABA is the method: payment data identifies a question. Knowledge of the service helps answer it.

A study of healthcare fraud controls published in the Journal of Insurance Medicine in 1996 examined a deeper weakness in claims-processing checks. Those checks tested whether the submitted information justified payment:

That explains why we care about what a technician or analyst saw. A claim can pass a payment check built around the information it contains. The person who was in the room can explain whether that information describes the session.

What the States Were Asked to Change

The Office of Inspector General’s recommendations put responsibility on state oversight as well as provider documentation. Colorado was asked to improve provider guidance, conduct statewide reviews after payment that include medical records, and examine the authorization contractor’s procedures. Wisconsin was asked to verify the rendering provider and review session notes after payment.

For an insider, the important connection is what changed inside the provider after a review or request for better documentation. We examine the notes and claims together with the explanations given for them. A payment system can ask for a better record. The people doing the work know whether the record became more accurate.

I Run a Behavioral-Therapy Company and Discovered Possible Medicaid Fraud by a Behavior Analyst. What Should I Report?

Talk with us about the treatment you know was delivered and how it differs from the claim or supporting record. We work through the state requirements, authorization, practitioner qualifications, supervision, session notes and billed units with you. Your firsthand knowledge supplies the connection between the clinical work and the payment.

We bring the clinical, billing and compliance perspectives together to evaluate a case about knowingly false Medicaid claims.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. Our role is to connect your knowledge to the payment and the decisions behind it, then bring in Medicaid fraud whistleblower lawyers with the experience your case needs.

You Know What Happened in the Session

If the treatment you delivered or reviewed became a different story on the Medicaid claim, speak with our whistleblower experts about that difference. We build the case with you around the session, the practitioner and the billing decisions, and stay beside you as the Medicaid fraud whistleblower lawyers we bring in pursue it.
