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

Hawaii's corporate-practice doctrine

Not verified. Searches found no Hawaii Attorney General opinion on corporate employment of physicians, and the annotations that were reported to list one were on the statute host that blocked access. This guide therefore cannot say whether Hawaii recognizes a corporate practice doctrine or what professions it reaches.

Is ABA a licensed profession in Hawaii

Yes. The Department of Commerce and Consumer Affairs licenses behavior analysts: "a license may be issued to applicants who have passed the Board Certified Behavior Analyst (BCBA) examination and maintain active status with the Behavior analyst Certification Board" (DCCA behavior analyst FAQ, file dated November 2015). That FAQ may be dated, and the licensing statute, HRS chapter 465D, was not read, so whether it contains any ownership or entity rule is unchecked.

Professional-entity rules and the form of the clinical entity

The DCCA instructions state that "a professional corporation may render professional services in this State only through individuals permitted to render such services in this State." A professional service is any service that may lawfully be rendered only by persons licensed under the listed chapters, including 453 (Medicine and Surgery) and 465 (Psychologists). "Not less than one-half of the directors" and all officers other than the secretary and treasurer "shall be qualified persons," meaning individuals eligible to own shares (DCCA, FORM PC-1-INSTR). The codified text of HRS 415A-2 and 415A-14 was not read, and whether Hawaii permits a professional LLC for these professions was not checked.

Who is allowed to own the clinical entity

Not verified. The professional corporation list in the agency instructions does not include behavior analysts, which suggests the professional corporation rules do not reach an ABA practice. That is an inference from a list, not a statement in the statute. Confirm with counsel whether a non-licensee may own a Hawaii ABA entity.

Where the strict rules catch you: in-house diagnostics

The archetypes split here. An ABA-only practice depends on the open point above. A practice with an in-house physician or psychologist adds professions that the agency instructions list as professional services, so any such service should sit in a professional corporation owned by qualified persons, separate from the ABA entity. The two ownership structures can then be linked by a management agreement.

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 runs the business. A management services agreement ties them together, and the clinical entity pays the MSO a fee. In many states the MSO exists to solve an ownership problem, because non-licensees cannot own the clinical entity. Whether Hawaii presents that problem for a pure ABA practice depends on the points above, and this guide says which of them could be verified.

When an MSO helps in Hawaii

If the ABA entity is open to non-licensee ownership, an MSO is a tool for scale, exits, and separating an in-house diagnostics entity. If counsel concludes the opposite, an MSO becomes the route for outside capital. See the practice expansion and sale hub.

Transaction notice and private equity review

No Hawaii health care transaction notice law covering ABA practices was found in the sources searched. Searches pointed to a hospital acquisition statute (HRS 323D-71 and following) and a 2026 bill, SB 3175, described in law firm alerts as a broader transaction notice proposal. Neither was read from an official source, and the bill's status is unknown.

How Hawaii would evaluate your arrangement

These are the factors to run, based on what this guide could verify.

Fee-splitting and how to pay an MSO

Hawaii fee-splitting rules were not verified. Whatever a state's own rules say, the safe design for a management fee is a fixed or cost-plus amount set to fair market value and traceable to documented services, not a percentage of clinical revenue tied to patient volume. Where the practice bills Medicaid, the federal anti-kickback statute applies to payments that can be linked to referrals or volume (42 U.S.C. § 1320a-7b(b)).

Keeping clinical control clean

No Hawaii control rule for ABA was verified. Keep clinical decisions with the licensed clinicians and document the management relationship at arm's length. The management company should not hire, supervise, or discipline clinicians on clinical grounds, set treatment hours, or override a treatment plan. That discipline protects the clinical entity in a payor audit or a transaction, and it becomes essential the moment a psychologist or physician joins the clinical chain.

Medicaid ownership disclosure and change of ownership

The Med-QUEST provider participation agreement states: "I/We agree to disclose full and complete information regarding ownership information as described in 42 C.F.R. §455 Subpart B," and the form refers to reporting a change in ownership within thirty-five days (Med-QUEST provider participation agreement, DHS 1139, Rev. 11/2022). The rule text itself, HAR 17-1736-19, was seen only on a secondary site.

How this connects to the rest of your compliance stack

Ownership rules are one layer. Three others 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 the Medicaid and insurance hub.
• Licensing. The credential each analyst must hold is a separate analysis. See Hawaii licensing and credentialing.
• Entity structure. Choosing direct ownership versus an MSO-plus-entity structure is its own analysis. See entity structures in Hawaii, and the facility licensure and HIPAA hub for what a change of ownership does to facility and records obligations.

Setting it up in Hawaii: the sequence

1. Confirm who may own the entity. Have counsel read HRS chapters 465D and 415A, since this guide could not.
2. Credential the practitioners. Confirm every analyst holds a current DCCA license.
3. Separate any second profession. Place physician or psychologist services in a professional corporation of qualified persons.
4. Price the management fee at fair market value. Fixed or cost-plus, documented, and compliant with the federal anti-kickback statute.
5. Plan the Med-QUEST disclosure. Prepare the full ownership stack and the 35 day change-of-ownership report.
