On March 24, the Indiana Capital Chronicle reported that FSSA Secretary Mitch Roob told ABA providers in a closed-door meeting that they must self-report any billing practices that could constitute fraud, waste, or abuse — by April 3.
That’s ten days’ notice.
This isn’t a proposed rule. It isn’t a public comment period. It’s a state Medicaid agency telling an entire provider class: come clean now, or we come find you.
And the self-reporting deadline is just one piece of a five-part enforcement package that takes effect over the next week. April 1, 2026 is shaping up to be the most consequential single day in ABA industry history.
What happened
A March 10 Wall Street Journal investigation named Indiana as “the nation’s hotbed of the booming autism therapy industry.” The numbers were staggering:
- Indiana’s Medicaid ABA spending went from $21 million in 2017 to $611 million in 2023 — a 2,900% increase in six years
- One provider, Piece by Piece Autism Centers, collected $29 million to treat 84 patients — roughly $340,000 per child
- Some providers were charging $600 per hour
- Indiana was home to 9 of the top 10 providers by per-patient spending nationally
The reason: Indiana’s reimbursement structure allowed providers to bill at whatever rate they wanted, with Medicaid paying 40% of the charged amount. Higher charges meant higher reimbursements. The incentive structure was, by design, uncapped.
Within two weeks of the WSJ article, FSSA Secretary Roob convened the meeting.
The five-part enforcement package
What makes Indiana unprecedented isn’t any single policy. It’s the combination — five major actions converging in the same week:
1. Self-reporting deadline: April 3
Providers must disclose any practices that could constitute fraud, waste, or abuse from before the program’s recent overhaul. Kim Dodson, CEO of the Arc of Indiana, described Roob’s tone as serious: “He was very disappointed in ABA providers because of that Wall Street Journal article.”
The implication is clear: self-report now and cooperate, or face consequences later when the state finds it themselves.
2. Lifetime cap: 4,000 hours, effective April 1
Indiana is implementing a lifetime allocation of 4,000 hours of ABA therapy per child. Once exhausted, children can access up to 15 additional hours per week if medically necessary.
The working group chose this over weekly caps and tiered care models. It’s more flexible — providers can front-load intensive treatment — but the total ceiling is firm. And it’s not retroactive: hours already used before April 1 don’t count against the cap.
3. Rate phasedown begins April 1
Reimbursement rates for individual ABA therapy are being reduced. The working group’s report authorized FSSA to “reduce current rates for individual ABA therapy as deemed necessary to stay within the agency’s appropriated budget.” Group therapy rates may increase, signaling a push toward group service delivery models.
4. New provider moratorium (timeline accelerating)
FSSA is requesting federal approval to temporarily block new providers or sites in designated counties from billing Medicaid. The moratorium follows the Florida model — AHCA imposed a similar freeze in Miami-Dade and Broward counties in 2018 in response to fraudulent overbilling. Existing providers stay in Medicaid; only new enrollments are blocked.
FSSA spokesman Marcus Barlow confirmed the moratorium and accreditation changes will be “accelerated,” though specific timelines haven’t been set.
5. Mandatory accreditation (accelerating)
Indiana currently has no accreditation or licensure requirements for ABA therapy organizations billing Medicaid — and no limits on provider growth. The working group agreed that must change.
The state is in “pre-conversations” with the Autism Commission on Quality (ACQ) about accreditation standards covering quality, service ratios, outcomes monitoring, risk management, and patient safety. Implementation is expected to be a yearlong process across all existing providers.
Why this matters beyond Indiana
Indiana isn’t acting in isolation. The same week these reforms take effect:
New York’s ABA Medicaid rate cut also hits April 1. Governor Hochul’s budget includes a 25% rate reduction phased through two 12.5% cuts. A provider survey found 72% will be forced to exit Medicaid if the second cut takes effect. That’s a potential access crisis for the state’s most vulnerable children.
April is Autism Acceptance Month. The industry enters its highest-visibility month under more regulatory scrutiny than it’s ever faced. Every legislator, payer executive, and journalist who read the WSJ investigation now has a reference point when ABA spending comes up in their state.
The OIG isn’t done. Federal audits have already documented $56 million in improper Indiana Medicaid payments for ABA. Audits in Wisconsin, Maine, and Colorado found documentation failures in 100% of sampled claims. More state audits are expected.
Centene is watching. The nation’s largest Medicaid MCO already stood up a 29-state ABA task force, hired BCBAs to audit BCBAs, and terminated providers in New York. Indiana’s enforcement gives payers additional justification to tighten their own oversight.
What providers should do now
Even if you don’t practice in Indiana, the enforcement model Indiana is building will be replicated. Florida did it in 2018. Indiana is doing it in 2026. Your state is watching.
This week:
-
Pull your billing data. Calculate your average per-patient annual cost. If you’re anywhere near the outlier thresholds that triggered Indiana’s review ($340K/patient, $600/hour), you need to understand why and document the medical necessity.
-
Audit your documentation against OIG findings. The same five failures appear in every federal audit: CPT code mismatches, missing signatures, non-therapy time billed as ABA, credentialing gaps, and missing assessments. If your system isn’t catching these before claims generate, that’s your vulnerability.
-
Check your supervision ratios. Centene is already flagging inadequate BCBA supervision as a billing vulnerability. Indiana’s accreditation standards will likely include supervision ratio requirements. Know your numbers.
-
Review your average treatment duration and hours per client. 40 hours/week for every patient and 5-10 year treatment durations are the patterns that draw scrutiny. If your caseload looks like that, either your documentation needs to clearly justify it or your clinical model needs to evolve.
This quarter:
-
Prepare for accreditation. Whether it’s ACQ, BHCOE, or a state-specific program, mandatory accreditation is coming. The providers who start now will be ready. The providers who wait will be scrambling.
-
Build your audit trail. The practices that survive increased scrutiny aren’t the ones that never make mistakes. They’re the ones that can show their work — treatment plans tied to assessments, session notes that match CPT codes, supervision logs that meet ratios, and outcomes data that demonstrates progress.
The bigger picture
More than 8,000 Indiana children rely on Medicaid to pay for ABA therapy. Most are between three and eight years old. Indiana has a waiting list of nearly 20,000 people for home and community-based services.
The providers who billed $600 an hour didn’t just commit fraud. They created the political conditions for the entire program to be cut. Every legitimate practice — the ones charging reasonable rates, documenting properly, and producing real outcomes — now operates under the cloud of an industry that failed to police itself.
Kim Dodson of the Arc of Indiana put it simply: “The consequences of abuse within the Medicaid system are being felt by families and people with disabilities.”
April 1 isn’t just a policy date. It’s the day the ABA industry finds out whether it built the infrastructure to survive real accountability.
StreamABA is built for the practices that want to prove their quality with data. Every feature — from CPT code validation at the point of entry to real-time supervision ratio tracking — exists because compliance shouldn’t be something you check after the fact.
