Key authorities (official text)
SDCL § 36-4-8.1 · ch. 47-11 (§§ 47-11-1, 47-11-3, 47-11-7) · § 34-52-2 · § 36-4-41§ 36-4-8.1 · Chapter 47-11, Medical Corporation Act · § 34-52-2 telehealth · § 36-4-41 · South Dakota Board of Medical and Osteopathic Examiners.
South Dakota CPOM is Moderate on Foundry's guide, and the doctrine is written into statute. SDCL § 36-4-8.1 says that, except as provided in chapter 47-11, it is the public policy of the state that a corporation may not practice medicine or osteopathy. Chapter 47-11, the Medical Corporation Act, lets one or more physicians licensed under the Medical Practice Act (chapter 36-4) form a corporation, or a professional limited liability company, to own and run a medical practice. § 47-11-3 says every officer, director, and shareholder must at all times be licensed under the Medical Practice Act, that no unlicensed person may have any part in the ownership or control of the corporation, and that no proxy to vote its shares may go to an unlicensed person. Sioux Falls and Rapid City diligence wants a physician-owned medical corporation plus a fair-market-value MSA.
Why Moderate and not Strict? § 36-4-8.1 also says a corporation is not practicing medicine, and is not violating § 36-4-8, when it employs a licensed physician under an agreement that passes three tests. The agreement or the relationship it creates may not (1) directly or indirectly supplant, diminish, or regulate the physician's independent judgment about the practice of medicine or the diagnosis and treatment of any patient; (2) result in profit to the corporation from the practice of medicine itself, such as charging more for the physician's services than the physician would reasonably charge as an independent practitioner, though the corporation may add charges reasonably tied to the services, such as facility, equipment, or administrative charges; or (3) stay in effect for more than three years, after which both parties may renew it annually. That employment path is narrow. A lay company that sets visit templates, books the professional fee as its own margin, or signs a five-year physician contract fails it on the face of the statute.
For a venture-backed MSO, the practical reading is simple. The employment exception describes how a corporation may pay a physician. It does not let the MSO own the practice, hold the claim TIN, or keep the profit on professional services. The clean South Dakota structure is still a medical corporation owned by a licensed physician, with the MSO paid a fixed or FMV-supported fee for non-clinical work.
§ 47-11-1 lets licensed physicians form the medical corporation under the general corporation law and lets licensed physicians and chapter 47-11 corporations form a limited liability company for the same purposes. In either form, medical or surgical treatment, consultation, or advice may be given by employees only if they are licensed under the Medical Practice Act. § 47-11-1.1 reads "shareholders" to include LLC members and "directors or officers" to include LLC managers. § 47-11-2 sets the name: a corporation ends with "chartered," "limited," "Ltd.," "professional association," "P.C.," or "PC," and a limited liability company includes "professional limited liability company," "Prof. LLC," "P.L.L.C.," or "PLLC."
§ 47-11-3 is the rule buyers open first, and it reaches further than ownership. Officers and directors must be licensed too. Your CEO cannot be the medical corporation's secretary or treasurer, and an investor cannot hold a voting proxy. § 47-11-3.1 allows a revocable trust to hold shares only while the grantor is alive and eligible to be a shareholder. § 47-11-4 sets a book-value buyout for a deceased or disqualified shareholder if the articles or bylaws do not fix a price, so put the buyout terms and the stock transfer restriction in the governing documents on day one. § 47-11-5 lets the medical corporation sign personal-services contracts with licensed physicians for whatever term the parties agree.
Registration is a separate gate from incorporation. § 47-11-7 says no corporation may open, operate, or maintain an establishment for the § 47-11-1 purposes without a certificate of registration from the Board of Medical and Osteopathic Examiners. Under § 47-11-8 the board investigates and issues the certificate only if every incorporator, officer, director, and shareholder is licensed, no disciplinary action is pending against any of them, and the corporation appears set to run in compliance with law and board rules. The certificate runs until the next January 1, must be posted on the premises (§ 47-11-9), must be amended on a change of location (§ 47-11-10), cannot be assigned (§ 47-11-11), and renews annually (§ 47-11-12). § 47-11-13 lets the board suspend or revoke it, including when a licensee who loses a license is not promptly removed, or when the last shareholder dies. § 47-11-20 says the chapter controls if it conflicts with the Medical Practice Act.
Licensure follows the patient. SDCL § 34-52-2 says a health care professional treating a patient in South Dakota through telehealth must be fully licensed in the state, or employed by one of the licensed facilities or programs the section lists, and is subject to the rules of the South Dakota licensing body. SDCL § 36-4-41 says a nonresident physician who, from outside the state, provides diagnostic or treatment services electronically to a patient in South Dakota under a contract with a South Dakota licensed provider, clinic, HMO, PPO, or licensed facility is practicing medicine in South Dakota. SDCL § 36-4-8 makes practicing medicine without a license a Class 1 misdemeanor.
A South Dakota charter is not a CPOM passport. If you treat North Dakota, Minnesota, Iowa, Nebraska, Montana, or Wyoming patients, those states control. Utah patients need a domestic Utah professional entity under Utah Code § 16-11-7. See Utah CPOM. Foundry does not cover any of those states with a plug-in network. Collaboration for PAs and NPs is a different job from owning the Professional Corporation. See collaborating physician vs physician PC owner.
Typical PC / MSO structure in South Dakota
When South Dakota patients or a South Dakota clinical entity are in scope, form a chapter 47-11 medical corporation (or professional LLC) owned, directed, and officered by a physician licensed in South Dakota, and register it with the board before the practice opens. The MSO provides non-clinical services under a written MSA at fair market value. Clinical revenue lands in the medical corporation. Physicians the corporation employs sign agreements that keep clinical judgment with them. Foundry forms that structure ($15,000) and matches a friendly PC owner ($3,000/mo). Not a rented Super PC, and not a lay corporation leaning on the § 36-4-8.1 employment sentence as its whole compliance file.
When you still need a PC vs only an MSO
Use the table as an operator rule, not a filing opinion. Confirm with counsel.
| South Dakota fact pattern | Typical entity | Why |
|---|---|---|
| South Dakota-only, physician already owns a registered medical corporation | Stay on the existing chapter 47-11 entity | Still document clinical control and an FMV admin fee if an MSO is in the picture |
| Venture-backed or multi-state telehealth that includes Sioux Falls, Rapid City, Aberdeen, or Brookings patients | Medical corporation + FMV MSA, with South Dakota licenses for the clinicians who see those patients | § 36-4-8.1 bars corporate practice outside chapter 47-11, and § 34-52-2 follows the patient |
| Lay corporation that employs physicians directly | Possible only inside the three-part § 36-4-8.1 test | No control of judgment, no profit from the practice itself, term of three years or less with annual renewal |
| South Dakota HQ with patients only in other states | Form for the patient states; a South Dakota HQ alone is not enough | CPOM follows the patient, not the HQ charter |
| South Dakota plus North Dakota, Minnesota, or Montana | Form for each neighboring state you treat | Each state has its own share and licensure rules |
Fee-splitting and funds-flow risk
The profit clause in § 36-4-8.1 is the funds-flow test buyers read most closely. A percentage-of-collections management fee looks like the corporation profiting from the practice itself. Prefer a fixed or FMV-supported admin fee. Clinical cash lands in the medical corporation. The MSO invoices it. Pair South Dakota with the fee-risk table on CPOM compliance.
| South Dakota pattern | Risk | Safer pattern |
|---|---|---|
| Lay corporation bills the professional fee and keeps the margin | High: § 36-4-8.1(2) profit from the practice itself | Medical corporation bills; MSO paid an FMV admin fee |
| MSO paid a percentage of professional collections | High: diligence and fee-split overlay | Fixed FMV admin fee with a memo |
| MSO executive serves as officer or director of the medical corporation | High: § 47-11-3 requires licensed officers and directors | Licensed physician fills every officer and director seat |
| Investor voting proxy or unlicensed shareholder | High: § 47-11-3 bars both | Stock transfer restriction and buyout terms in the bylaws |
| Physician employment agreement longer than three years | Fails § 36-4-8.1(3) | Three-year term or less, then annual renewal |
| Practice opened before the board certificate issues | § 47-11-7 problem | Register first, post the certificate, renew each year |
| Physician-owned medical corporation + FMV MSA + separate books | Base case | Revisit FMV when volume changes |
Board vs buyer / payer checks
Licensing boards discipline licensees and register medical corporations. Buyers and payers run a different file. Use both columns. Full operating map: CPOM compliance.
| Who checks | What they sample | South Dakota fail signal |
|---|---|---|
| Board of Medical and Osteopathic Examiners | Current certificate of registration; licensed incorporators, officers, directors, and shareholders; annual renewal | Lapsed certificate; an unlicensed officer; a licensee who lost a license and was not removed |
| Buyer diligence | Shareholder ledger and officer slate vs § 47-11-3; physician employment terms vs § 36-4-8.1; one claim from payer to PC bank to MSA invoice | MSO lockbox; percentage MSA; lay proxy; five-year physician contract |
| Payer / credentialing | Claim TIN and group NPI on the physician-owned medical corporation | Marketing MSO TIN on the claim |

South Dakota CPOM FAQ
Does South Dakota have CPOM?
Yes. SDCL § 36-4-8.1 bars corporate practice outside the Medical Corporation Act. Foundry rates South Dakota Moderate on the CPOM 50-state guide because the same section allows physician employment that passes a three-part test. Ownership of a medical corporation stays with licensed physicians under § 47-11-3.
Do I still need an MSO-PC in South Dakota?
Yes for most venture-backed and multi-state models that treat South Dakota patients. The medical corporation holds clinical care and the claim TIN; the MSO is paid fair market value for non-clinical services.
Can an MSO executive be an officer of a South Dakota medical corporation?
No. § 47-11-3 requires every officer, director, and shareholder to be licensed, and bars proxies to unlicensed people. Keep the MSO team in the MSO.
Does a South Dakota entity replace state-by-state CPOM?
No. The rules follow the patient. Form for each patient state on the CPOM 50-state guide, including North Dakota and Minnesota. Utah patients need a domestic Utah professional entity. See Utah CPOM.
How does Foundry help with South Dakota CPOM?
MSO-PC formation is $15,000 one-time. A licensed physician PC owner is $3,000/mo. Foundry is not a law firm.
