Why ABA Is Facing So Many Audits and Closures Right Now — And What It Actually Means for New RBTs

If you’ve been seeing headlines about ABA companies getting investigated or shutting down — like Piece by Piece Autism Centers in Indiana closing in May 2026 after averaging $340,000 per patient in Medicaid payments — you’re probably wondering what’s really going on.

This isn’t random. It’s the result of years of extremely fast growth in Medicaid-funded ABA with relatively weak oversight in several states.

As ABA services expanded rapidly, some providers scaled aggressively. A handful pushed billing practices to extremes. The Wall Street Journal investigations and multiple federal OIG audits have been bringing this to light. So far, the audits have found:

• Colorado: At least $77.8 million in improper Medicaid payments for ABA (with potentially improper payments adding significantly more).
• Indiana: Over $56 million in improper payments.
• Similar large findings in Wisconsin and Maine.

The most common issues across these audits are consistent: incomplete or insufficient session notes, weak documentation of supervision, and billing for services that didn’t clearly meet documentation or medical necessity requirements.

Why is this happening now?

For several years, the main focus in many states was expanding access to ABA as quickly as possible. Money flowed in, but the systems for supervision, auditing, and compliance didn’t grow at the same pace. Once ABA spending became one of the fastest-growing parts of Medicaid in several states, regulators and state budgets started paying much closer attention.

We’re now in the “reckoning” phase. States are under fiscal pressure, and cases of aggressive billing or poor documentation are triggering a strong response: more audits, heavier scrutiny, and in some cases, providers being forced to shut down.

What does this actually mean for you as a new RBT?

It’s not that every provider is in trouble. Most of the audits are targeting clear patterns of abuse or serious documentation failures. However, the overall standard is rising for everyone.

Your documentation is no longer just admin work — it’s protection. In this environment, clear, objective session notes that demonstrate medical necessity have become a form of job security. Companies that invested in strong documentation systems and proper supervision are much better positioned to survive this wave of scrutiny. The ones that treated compliance as an afterthought are paying the price.

Long-term, this will likely push the field toward higher professionalism and accountability. Short-term, it means more pressure on documentation quality — and more value for RBTs who can document well and work inside compliant systems.

The uncomfortable reality is that a small number of providers damaged trust across the entire field. Now everyone has to deal with tighter standards. The RBTs who treat documentation as a real clinical skill (not just something you rush through at the end of the day) are going to be in a stronger position moving forward.

If you’re early in your career, pay attention to how the companies you work for — or are considering joining — handle documentation, supervision, and compliance. That’s now one of the clearest signals of long-term stability.
