ABA Therapy Medicaid Crackdown: What the Indiana Investigation Means for Families

A major story unfolding in 2026 is sending ripples through the ABA therapy world -- and it has direct consequences for families who depend on Medicaid to pay for their child's autism treatment.

In March 2026, Indiana barred Piece by Piece Autism Centers from billing the state Medicaid program after investigators found the company had collected an average of $340,000 per patient in a single year -- billing at rates as high as $640 per hour. The company, which operated seven centers in Indiana, announced it would shut down entirely by May 15, 2026. Operations are being transferred to Applied Behavior Center for Autism, another Indianapolis-based provider.

This is not an isolated case. Federal and state regulators are increasing oversight of ABA therapy billing nationwide. Here is what families need to understand -- and how to protect themselves.

What Happened in Indiana

A March 2026 Wall Street Journal investigation brought national attention to the billing practices at Piece by Piece Autism Centers. In 2023, Indiana Medicaid paid the company $29 million for ABA services provided to just 84 patients -- roughly $340,000 per child per year. For context, typical annual ABA therapy costs run $40,000 to $100,000 per patient, depending on hours and location.

Following the report, Indiana's Family and Social Services Administration (FSSA) revoked Piece by Piece's Medicaid provider agreements at all seven locations. The state also demanded that all ABA providers self-report any fraud, waste, or abusive billing practices by April 3, 2026.

This story is part of a broader pattern. Medicaid spending on ABA therapy has grown dramatically across the country as autism diagnosis rates have risen and insurance mandates have expanded. In North Carolina, for example, ABA Medicaid spending reached $639 million in fiscal year 2026 -- a 423% increase from $122 million in fiscal year 2022. This rapid growth has drawn regulatory scrutiny at both the state and federal level.

What This Means for Affected Families

For children who were receiving services at Piece by Piece, the closure is a serious disruption -- regardless of the billing disputes happening above them at the corporate level. Children with autism who depend on consistent ABA therapy do not simply pause their development while families search for alternative providers.

This is the hidden cost of provider misconduct: the families are the ones who bear the greatest real-world disruption when providers are held accountable. Established therapeutic relationships take time to rebuild. New providers may use different approaches, have waitlists, and require new insurance authorizations that take weeks to process.

The Broader Pattern: ABA Medicaid Scrutiny Is Growing

Federal and state regulators are tracking a wider set of billing concerns across the ABA industry. Legal analysts have identified several patterns drawing heightened scrutiny:

• Upcoding -- billing for more intensive service levels than were actually delivered
• Billing for services not rendered
• Excessive authorized hours without adequate medical necessity documentation
• Supervision deficiencies -- programs where RBTs (Registered Behavior Technicians) deliver services without adequate BCBA oversight

States are responding with new safeguards. Indiana has introduced rate reforms, stricter authorization requirements, and -- effective October 2026 -- an age limit cutting off Medicaid-funded ABA for adults 21 and older. Other states are closely watching Indiana's reforms and may introduce similar measures in the coming year.

How to Protect Your Family

The vast majority of ABA providers operate with integrity. Thousands of dedicated BCBAs and RBTs across the country are doing important, ethical clinical work every day. But families relying on Medicaid-funded ABA should take these practical steps to protect themselves.

Verify Your Provider's Credentials

Confirm that a Board Certified Behavior Analyst (BCBA) is actively supervising your child's program -- not just listed on paperwork. The BACB (Behavior Analyst Certification Board) maintains a free public certificate verification tool at bacb.com where you can confirm any clinician's certification status.

Review Your Explanation of Benefits

If your Medicaid managed care plan sends an Explanation of Benefits (EOB), take a few minutes to review it. Check that the dates of service, hours billed, and service codes match what you know about your child's actual therapy. Errors and irregularities do happen, and catching them early protects both you and the Medicaid program.

Understand What Proper Supervision Looks Like

Under BACB guidelines, RBTs delivering therapy must receive ongoing supervision from a BCBA -- typically a minimum of 5% of the hours they work, including direct observation of sessions. Ask your provider how often the supervising BCBA observes sessions directly and reviews your child's data. Supervision should be visible and consistent, not invisible.

Know Your Rights If Your Provider Closes

If your ABA provider closes or loses Medicaid authorization, contact your Medicaid managed care plan or your state Medicaid office immediately. Federal law requires managed care plans to support members in transitioning to new providers and to ensure continuity of care during the transition. Do not wait to start the process -- early action significantly reduces gaps in service.

Watch for These Warning Signs

Ethical ABA providers base hour recommendations on your child's clinical needs, not on maximizing authorized hours. Be alert to:

• Pressure to accept the maximum authorized hours without individualized clinical justification
• High staff turnover with little explanation
• The supervising BCBA appearing rarely or only briefly in your child's sessions
• Vague, unavailable, or hard-to-understand progress data
• Billing amounts that seem significantly higher than the hours of service you observed

What Increased Oversight Means in the Long Run

While provider closures are painful for families in the short term, accountability in ABA billing is ultimately good for the field and for families. When a small number of bad actors dramatically inflate costs, it strains the Medicaid budgets that fund care for thousands of families -- and it invites blunt policy responses like hour caps, age limits, and rate cuts that affect every family, regardless of their provider's conduct.

Greater accountability should, over time, help build a more sustainable and trustworthy system for families who depend on Medicaid for ABA access.

Finding a Provider You Can Trust

The best protection for your family is starting with a provider who has a strong reputation, verifiable credentials, transparent billing practices, and a real track record of clinical outcomes.
