South Carolina licenses behavior analysts and assistant behavior analysts through the Department of Labor, Licensing and Regulation, under the board that also regulates professional counselors and marriage and family therapists (S.C. Code Title 40, Chapter 75; § 40-75-5 et seq.). South Carolina does not require professionals, even physicians, to operate exclusively as a professional corporation, and it has no professional limited liability company, so licensed professionals may use an ordinary LLC (S.C. Code Title 33, Chapter 44). Its corporate-practice doctrine is common law reaching medicine and optometry, so it does not force licensed ownership of an ABA practice, a non-licensee may own the entity, and an MSO is optional. A transition provision allowed certain unlicensed providers approved by the Department of Health and Human Services to continue only until December 31, 2026. South Carolina has no general health care transaction-notice law. Federal anti-kickback rules apply to any Medicaid arrangement (42 U.S.C. § 1320a-7b(b)).

South Carolina's corporate-practice doctrine
South Carolina recognizes a corporate-practice-of-medicine doctrine, but it comes from common law rather than an explicit statute, grounded in the 1938 decision in Ezell v. Ritholz that a lay-owned company could not practice a licensed profession by employing licensed practitioners. Its reach is to medicine and the licensed clinical professions the courts had in view, and South Carolina notably does not mandate that even physicians operate exclusively through a professional corporation. Behavior analysis is licensed on its own track through the Department of Labor, Licensing and Regulation, so no rule forces an ABA practice into licensed ownership.
ABA is a licensed profession in South Carolina
South Carolina licenses behavior analysts and assistant behavior analysts through the Department of Labor, Licensing and Regulation, under the board that also regulates professional counselors, marriage and family therapists, addiction counselors, and psycho-educational specialists (S.C. Code Title 40, Chapter 75; § 40-75-5 et seq.). A transition provision permitted certain unlicensed providers who had been approved by the Department of Health and Human Services to continue only until December 31, 2026. Because ABA is regulated by LLR on its own track and is not the practice of medicine, the medical ownership principles do not reach it.
LLR licensure, no forced professional form, and the 2026 transition
Two South Carolina-specific points shape the structure. First, South Carolina is unusually flexible on entity form: it does not require even physicians to operate exclusively through a professional corporation, and it has no professional limited liability company at all, so licensed professionals routinely use an ordinary LLC under the general LLC Act (S.C. Code Title 33, Chapter 44). The professional corporation and professional association remain available under Title 33, Chapter 19, and if a professional corporation is used its owners must be licensed in the same profession, but the form is optional. Second, South Carolina ran a licensure transition: certain unlicensed providers approved by the Department of Health and Human Services could continue only until December 31, 2026, after which practice is limited to licensees and exempt persons. That transition affects who may practice, not who may own, so ownership remains open, and there is no general health care transaction-notice law to build in.
Who is allowed to own the clinical entity
For a pure ABA practice, a non-licensee may own the clinical entity in South Carolina. Because the state does not force professionals into the professional-corporation form and its corporate-practice doctrine reaches medicine and optometry rather than behavior analysis, an ABA practice may be organized as an ordinary limited liability company, owned in whole or in part by a non-licensee, that employs licensed behavior analysts (S.C. Code Title 33, Chapter 44; Title 40, Chapter 75). The professional corporation under Title 33, Chapter 19 is available and licensee-owned if elected, but it is not required. So the entity choice is a tax-and-liability decision, not an ownership constraint.
South Carolina does not force even physicians into a professional corporation, and its corporate-practice doctrine is common law reaching medicine and optometry. An ABA practice may be an ordinary LLC owned by a non-licensee.
Where the strict rules catch you: in-house diagnostics
The open answer is specific to a pure ABA practice. If a different licensed profession joins your clinical chain, that profession's rules apply to its service. The common trigger is in-house diagnostics: a licensed psychologist performing diagnostic evaluations brings the psychology license and the common-law corporate-practice concerns to bear on that service, and a physician adding psychiatry or medication management brings the medical doctrine, which Ezell v. Ritholz squarely supports. A multidisciplinary South Carolina group therefore tends to place the psychology or medical service in a separate, licensee-owned professional entity, keep the ABA entity as an openly owned LLC, and tie the two together with a management agreement. The South Carolina 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 South Carolina 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.

- Obscure the true owners at Medicaid enrollment
- Override professional judgment
When an MSO helps in South Carolina, since it is not required
Because ownership is open for pure ABA, the South Carolina MSO decision is strategic. 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 a South Carolina 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 LLC. For a single-site, ABA-only South Carolina practice, direct ownership through an ordinary LLC is usually the simplest path. See the practice expansion and sale page for the transaction view.
How South Carolina would evaluate your arrangement
South Carolina's questions are about licensure currency, form, and whether a second profession is in the chain, not ABA ownership. These are the factors to run.
Pure ABA ownership open
Is the entity owned by a non-licensee where desired, given the state does not force the professional form and the doctrine reaches medicine and optometry?
Licensure current
Are the behavior analysts licensed through LLR (S.C. Code Title 40, Chapter 75), given the transition ended December 31, 2026?
Transition confirmed
For any previously DHHS-approved provider, has the move to full licensure been completed?
Second profession separated
If a psychologist or physician is in the clinical chain, is that service placed in a separate, licensee-owned professional entity?
Fee at fair market value
Is any MSO fee a fair-market-value payment for services, not a share tied to referrals or volume?
Federal overlay for Medicaid
For Medicaid clients, does the structure satisfy the federal anti-kickback statute?
Fee-splitting and how to pay an MSO
South Carolina 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
South Carolina 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 and becomes essential the moment a psychology or medical service is added. Run business and clinical roles as though separate, especially if you plan to expand into corporate-practice states or add in-house diagnostics.
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 South Carolina: the sequence
- Confirm pure-ABA ownership is open. The state does not force the professional form and the doctrine reaches medicine and optometry, so a non-licensee may own an ordinary LLC.
- License the practitioners. Behavior analysts licensed through LLR (S.C. Code Title 40, Chapter 75), noting the transition ended December 31, 2026.
- Confirm any provider transitions. For previously DHHS-approved providers, confirm the move to full licensure is complete.
- 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.
- Price the management fee at fair market value. Fixed or cost-plus, documented, and compliant with the federal anti-kickback statute for Medicaid.

Where professional advice is essential, not optional
South Carolina is a permissive state for pure ABA ownership, so counsel's job is to confirm licensure currency after the 2026 transition, the entity form, and the fee structure, and to separate any second licensed profession cleanly. Confirm that ownership is open for your model, that practitioners are fully licensed through LLR, that any in-house diagnostics sit in a licensee-owned entity, and that any MSO fee is at fair market value, with South Carolina counsel.
The governing authorities to know are the behavior-analyst licensing provisions (S.C. Code Title 40, Chapter 75, § 40-75-5 et seq.) and the professional corporation and LLC chapters (S.C. Code Title 33, Chapters 19 and 44), with the federal anti-kickback statute (42 U.S.C. § 1320a-7b(b)) layered on for Medicaid.
