Indiana Will Require Accreditation for Medicaid ABA Agencies

INDIANAPOLIS – Indiana will stop paying applied behavior analysis agencies that are not accredited. Under a bulletin the state issued in March, every newly enrolled and existing ABA group in the Indiana Health Coverage Programs (IHCP), the state’s Medicaid program, must be accredited by a recognized body by Oct. 1, 2027. The deadline providers are watching is much closer. Any agency already in the program has until August 1, 2026, to document that it has at least started the process, or the state will deactivate its enrollment.

The rule recognizes two accrediting organizations: the Autism Commission on Quality (ACQ) and the Behavioral Health Center of Excellence (BHCOE). Both are now controlled by the same trade group, a detail that turns a quality mandate into a question about who holds the keys to Medicaid revenue in the state.

Indiana is not the first state to take this step, and the people who run the accreditors expect it will not be the last. For ABA operators, accreditation is shifting from a credential that signals quality to a license to bill.

What the Bulletin Requires

The policy arrived in IHCP Bulletin BT202646, dated March 26, 2026. It sets two dates. By Aug. 1, 2026, every ABA group already enrolled must submit documentation showing it has initiated accreditation, either by emailing the state’s enrollment contractor or uploading a current accreditation through the IHCP provider portal. By Oct. 1, 2027, every agency must have finished the process and remain actively accredited to keep billing.

The penalty is blunt: an agency that misses the August documentation deadline will have its enrollment deactivated, according to the bulletin. The state framed the rule as a way to hold ABA agencies to consistent national standards for clinical quality, organizational oversight and ethical practice.

A footnote addresses providers already carrying a BHCOE credential. Indiana will accept an existing BHCOE accreditation until that agency comes up for reaccreditation with ACQ, signaling that the state sees ACQ as the destination over time.

Two Accreditors, One Owner

On paper Indiana names two accreditors. In practice the choice narrowed in December 2025, when the Council of Autism Service Providers (CASP), the industry’s main trade group, acquired Jade Health, the parent of BHCOE. CASP already operated ACQ, which it founded in 2022. The acquisition put both bodies the state recognizes under one roof.

CASP has said it will honor existing BHCOE accreditations in the near term, then fold the two frameworks into a single program run under the ACQ name. New applicants, in other words, are heading toward one accreditor. CASP is a nonprofit trade association that serves roughly 440 member organizations, and it has been candid that accreditation is becoming a condition of doing business.

“Governments are trying to figure out what is quality care and what is not. They need a third-party, neutral entity to evaluate providers.” – Lorri Unumb, CEO, Council of Autism Service Providers (2026)

Industry insiders believe that the number of states and health plans requiring accreditation would climb sharply, and would increase exponentially in the near term. More than a dozen payers already require an ABA provider to hold ACQ or BHCOE accreditation, according to the group. By naming those bodies, Indiana effectively outsourced the job of defining acceptable practice to a private third party.

The Cost and Timeline of Accreditation

For an operator facing the August deadline, the practical questions are price and time. ACQ’s application pricing starts at a minimum fee of $4,500 for smaller organizations and scales up with the volume of reimbursable service hours an agency provides, according to the body’s published guidance. The review is not a paperwork exercise. It includes a desktop review of policies, leadership interviews, clinical observations and satisfaction surveys from clients and staff, and ACQ says completion can take anywhere from under six months to about a year.

Chrissy Barosky, chief clinical officer at Indiana-based Bierman Autism Centers, which operates 32 clinics across seven states, described accreditation to Behavioral Health Business as a rigorous, months-long process that forces an organization to examine every policy and procedure against the standards. She supports the shift. The field needs standards, she said, so that families and payers can be assured everyone is meeting a minimum level of care.

Capacity is the open question. Indiana’s own ABA working group, whose recommendations prompted the rule, warned that the state should allow enough time for all providers to comply and should confirm the accrediting body has the bandwidth to finish reviews on schedule. With hundreds of Indiana agencies and a growing list of agencies in other states routing toward the same reviewer, the timeline is the variable that will decide whether the mandate widens or narrows access.

Massachusetts Set the Precedent

Indiana is following a path Massachusetts cut first. Effective Jan. 1, 2025, MassHealth, the state’s Medicaid program, began requiring its managed care entities to contract only with accredited ABA providers. Center-based providers must be accredited by Jan. 1, 2027, and all other providers by Jan. 1, 2028. Massachusetts recognized the same two bodies, ACQ and BHCOE, and its move followed Medicaid billing settlements and an inspector general finding that the program lacked proper quality controls.

Why Indiana, Why Now

The accreditation rule is one piece of a broader reform effort on what had been one of the fastest-growing lines in Indiana’s Medicaid budget. ABA spending peaked at $611 million in 2023 and fell to $445 million in 2024 after the state set standardized rates, according to the working group’s report.

A March 2026 Wall Street Journal investigation called Indiana the nation’s hotbed of the autism therapy industry and reported that nine of the 10 highest-billing providers by per-patient spending in 2023 operated there. More than 8,000 Hoosiers rely on Medicaid for ABA, most of them children between three and eight, according to the Indiana Capital Chronicle.

Accreditation now carries a second weight in Indiana. On June 6, the state began a six-month moratorium, approved by the federal Centers for Medicare & Medicaid Services, that blocks new ABA group enrollments and ownership changes. Agencies seeking an exception must be accredited under the same March bulletin, making the credential both a condition of staying in the program and the only route around the freeze.

The first real test is Aug. 1, when documentation comes due and the state begins switching off agencies that cannot show they have started. The enrollment moratorium is set for its first six-month review in December.
