Do you need an MSO for your ABA practice in Indiana?

Indiana's corporate-practice doctrine

Indiana does not apply a corporate-practice doctrine that reaches behavior analysis. Its professional-corporation statute carries licensed-owner rules for practices that elect that form, but Indiana does not force licensed professions generally into it, and it is a permissive state where non-licensees may own health care businesses. Behavior analysis is regulated as its own profession, so no doctrine forces an ABA practice into licensed ownership.

ABA is a licensed profession in Indiana

Indiana licenses behavior analysts, with the credential administered through the Indiana Professional Licensing Agency under the Medical Licensing Board (Indiana Professional Licensing Agency, behavior analyst licensure). Although the credential sits within the medical licensing agency, the practice of behavior analysis is regulated as its own profession and is not the practice of medicine, so the ownership and corporate-practice principles that govern physicians do not attach to it. Licensure is the gateway, without an ownership rule for ABA.

Indiana's broad 2024 transaction-notice law

The Indiana-specific point for an MSO is a notably broad deal-notice law. Effective July 1, 2024, Senate Enrolled Act 9 requires an Indiana health care entity involved in a merger or acquisition with another health care entity that has at least $10 million in total assets to notify the Attorney General at least 90 days before closing, and the Attorney General may analyze antitrust concerns and issue a civil investigative demand (Senate Enrolled Act 9 (2024)). The definition of health care entity is broad, reaching behavioral health providers, management services organizations, and private equity partnerships, and the law covers indirect acquisitions. Because the MSO is where enterprise value builds for a sale, any significant Indiana transaction should be screened against this law and its 90-day timing built into the deal.

Who is allowed to own the clinical entity

For a pure ABA practice, a non-licensee may own the clinical entity in Indiana. Indiana's professional-corporation form carries licensed-shareholder and licensed-director requirements, but Indiana does not force behavior analysis into that form and applies no corporate-practice doctrine reaching ABA, so the practice may be organized as an ordinary corporation or limited liability company with non-licensee ownership (IC 23-1.5-2-3). If the professional-corporation form is used, at least one shareholder must be Indiana-licensed and directors and officers licensed, with the secretary and treasurer excepted (IC 23-1.5-2-4), but the form is optional. So the entity choice is a tax-and-liability decision, with the 2024 transaction-notice law as the deal-stage consideration.

Where the strict rules catch you: in-house diagnostics

The open answer is specific to a pure ABA practice. The moment a different licensed profession joins your clinical chain, that profession's rules apply to its service. If a licensed psychologist performs in-house diagnostic evaluations, that psychology service carries the psychology license and the professional-corporation rules as they apply to psychology, and if a physician adds psychiatry or medication management, that service is the practice of medicine and within the corporate-practice doctrine. A multidisciplinary Indiana group therefore tends to place the psychology or medical service in a separate professional corporation owned by the relevant licensees, keep the ABA entity openly owned, and tie the two together with a management agreement. The Indiana question is whether a licensed profession beyond behavior analysis touches your clinical chain. If not, you are in the open lane.

What a management services organization actually is

An MSO is a separate company that provides the non-clinical side of a practice to a clinical entity it does not own. The clinical entity employs the clinicians and delivers care. The MSO employs everyone else and runs the business. A management services agreement ties them together, and the clinical entity pays the MSO a fee. In most states the MSO exists to solve an ownership problem, because non-licensees cannot own the clinical entity. In Indiana there is usually no ownership problem to solve, so the MSO is a tool of convenience, useful for scaling across sites or preparing for a transaction, rather than a compliance necessity.

When an MSO helps in Indiana, since it is not required

Because ownership is open for pure ABA, the Indiana MSO decision is strategic, with a significant deal-notice caveat. An MSO helps when an operator runs multiple entities and wants one management platform, when a group is preparing for a sale and wants enterprise value to accumulate in a scalable company, when an Indiana practice belongs to a multi-state group that uses the MSO-PC structure in stricter states, or when the group adds in-house diagnostics and must separate a licensee-owned entity from the openly owned ABA entity. In each case, screen any significant transaction against the 90-day Attorney General notice. See the practice expansion and sale page for the transaction view.

How Indiana would evaluate your arrangement

Indiana's questions are about form, fees, a broad deal notice, and whether a second profession is in the chain, not ABA ownership. These are the factors to run.

Fee-splitting and how to pay an MSO

Indiana does not impose a broad ABA-specific fee-splitting statute, so management-fee economics are governed mainly by the federal anti-kickback statute where the practice bills Medicaid, and by payor contract terms (42 U.S.C. § 1320a-7b(b)). The safe design remains a fixed or cost-plus management fee set to fair market value and traceable to documented services, rather than a percentage of clinical revenue tied to patient volume.

Keeping clinical control clean

Indiana does not force a clinical-control firewall on a pure ABA practice, but keeping clinical decisions with the licensed behavior analysts and documenting the management relationship at arm's length serves any future transaction, particularly given the broad transaction-notice review, and becomes essential the moment a psychology or medical service is added. Run business and clinical roles as though separate.

How this connects to the rest of your compliance stack

Ownership is permissive, but three other layers still bind:

• Payor and Medicaid disclosure. Your real ownership stack, including any MSO, is disclosed at enrollment and revalidation regardless of how it looks on paper (42 C.F.R. Part 455). See Medicaid and insurance mandates.
• Facility licensure. A change in the ownership or service model can affect facility and records obligations. See facility licensure and HIPAA.
• Entity structure. Choosing a direct-ownership entity versus an MSO-plus-entity structure is its own analysis in a permissive state. See entity structures for ABA practices.

Setting it up in Indiana: the sequence

1. Confirm pure-ABA ownership is open. No corporate-practice doctrine reaches ABA and the PC form is optional, so a non-licensee may own an ordinary entity.
2. License the practitioners. Behavior analysts licensed through the Indiana Professional Licensing Agency.
3. Own it directly, or add an MSO by choice. A non-licensee may own the ABA entity; add an MSO for scale, exits, multi-state, or to separate a diagnostics entity.
4. Separate any second profession. If a psychologist or physician is in the chain, place that service in a licensee-owned professional entity and manage it under an MSA.
5. Build in the 90-day notice. Screen any merger or acquisition against Senate Enrolled Act 9 and its 90-day timing.
