Who Can Own a Med Spa in Michigan? 2026 CPOM Rules

Ask ten Michigan advisers who may own a med spa and you get two irreconcilable answers. One camp says only a physician may own a medical practice here. The other says Michigan barely enforces the corporate practice of medicine at all. Both are quoting something real, and the disagreement is what sends aspiring owners into a structure they later have to unwind.

The reconciliation is that Michigan's restriction is unusually narrow in reach and unusually hard in application. It comes from a short statutory list rather than a sweeping judicial doctrine, so much of Michigan's wellness economy falls outside it entirely. Cross into medicine and the rule admits no percentages and no good-faith exceptions. This guide walks that line under the Michigan Business Corporation Act, the Michigan Limited Liability Company Act, and the Michigan Public Health Code administered by LARA and the Michigan Board of Medicine. Settle staffing first — our guide to who can inject Botox in Michigan constrains every answer below.

Michigan's Corporate Practice of Medicine Posture: A Statute, Not a Doctrine

Most states that restrict medical ownership do it through a judicially developed doctrine that a medical board and a plaintiffs' bar then enforce. Michigan took a different route, and that difference explains nearly every disagreement about how strict the state is.

Where the Michigan rule actually comes from

Michigan's Attorney General concluded in OAG No. 2451 (March 7, 1956) that the practice of medicine was not a lawful corporate purpose, and that conclusion produced the Professional Service Corporation Act rather than a line of case law. The act was repealed in 2012 and folded into the Business Corporation Act as Chapter 2A, MCL 450.1281 to 450.1289, effective January 2013; the parallel LLC provisions sit at MCL 450.4901 to 450.4910. So Michigan has no common-law prohibition a court can stretch — it has a filing requirement with teeth, and a Public Health Code that disciplines the licensee who ignores it.

The learned-profession definition does most of the work

The operative trigger is MCL 450.1281: a corporation must incorporate as a professional corporation if formed to provide one or more services in a learned profession. That phrase is defined at MCL 450.1109 for corporations and in the mirror provision at MCL 450.4102 for LLCs, and the list is short — a dentist, an osteopathic physician, a physician, a surgeon, a doctor of divinity or other clergy, or an attorney-at-law. Nobody else is on it. A business rendering none of those services is not caught, which is why so much of the wellness market sits outside the rule while the injectables clinic next door sits inside it.

How Michigan compares to California and New York

The comparison is worth making precisely, because the shorthand misleads in both directions. New York routes professional entity formation through an Education Department approval step Michigan does not impose, and California layers an active medical board enforcement programme on top of its statute. In reach, Michigan is the more permissive of the three. On the narrow question of who may hold shares, California is more accommodating: its professional corporation statute lets registered nurses, physician assistants and a dozen other licensees hold up to 49% of a medical corporation. Michigan has no minority-ownership allowance at all.

Who Can Own a Michigan Med Spa: The Ownership Table

Here is the fast reference. The qualifier column matters more than the verdict column — in Michigan the same person can own one entity and not another, depending entirely on what that entity is formed to render.

Read the table against your service menu rather than your job title. Michigan does not license med spas, and no registration exists in which the state blesses your structure — the classification happens the first time a regulator or a buyer looks at what you actually sell.

Professional Corporations and PLLCs: Who May Hold Shares

If the business renders medicine, Chapter 2A of the Business Corporation Act or Article 9 of the LLC Act governs the equity. These provisions decide the ownership question, and they are more particular than most operators expect.

MCL 450.1283 and the shareholder test

One or more licensed persons may form a professional corporation, and the articles must state the specific professional service or services it provides. Every shareholder must be a licensed person in one or more of the professional services provided by the corporation, or an entity owned directly or beneficially only by such licensed persons. The definition at MCL 450.1282 reaches an individual authorised to practise, and also a corporation, partnership or LLC all of whose owners are licensed persons — which is how a physician holds their interest through a holding entity without breaking the chain. What it never reaches is a person with no licence.

The same-service rule for Public Health Code services

The general test loosens where an entity provides several professional services, but health care gets a tighter overlay. Under MCL 450.4904, if a professional limited liability company renders a professional service included within the Public Health Code, all members and managers must be licensed to render the same professional service, subject to the specific statutory combinations. MCL 450.1284 makes the professional corporation subject to the Public Health Code at MCL 333.16101 to 333.18838. Mixing licence types in the medical entity is therefore not a matter of negotiating percentages — it is permitted only where a statute names the combination.

The 2022 multidisciplinary amendment — and who it left out

2022 PA 31 and 2022 PA 32, effective March 2022, amended the LLC Act and the Business Corporation Act to let individuals licensed in chiropractic organise a PLLC or PC with individuals licensed in chiropractic, medicine, osteopathic medicine and surgery, or podiatric medicine and surgery. Physicians may separately organise with one or more physician assistants. That is the entire multidisciplinary permission. Nursing was not added in 2022 and has not been added since — so the amendment cited as evidence Michigan is loosening up did nothing for the licence type most likely to run a med spa.

Share transfers, directors, and the paperwork that outlives you

Ownership restrictions do not stop at formation. Shares of a professional corporation may pass only to a person eligible to hold them — another qualifying shareholder, the personal representative of a deceased or incapacitated shareholder, who may not decide anything about the professional service, or a qualifying trust. Build the buy-sell mechanics in on day one; the alternative is discovering that an estate has inherited shares nobody may hold. Non-compliance can put the entity itself at risk of forfeiture or dissolution.

Can a Non-Physician Own a Med Spa in Michigan?

This is the question that brings most readers here, and Michigan answers it in two parts that turn on what the business does rather than who is asking.

What a person with no health care licence cannot own

Verdict: not the entity that renders medicine. If your menu includes botulinum toxin, dermal filler, prescription weight-loss injections, or laser treatment for dermatological purposes, the treating entity provides physician services. It must be a PC or PLLC, and MCL 450.1283 shuts a non-licensee out of the share register completely — no minority stake, no non-voting class, no consulting workaround. A lay person holding equity in a Michigan medicine PC has an entity that was never validly constituted for the purpose.

What a person with no health care licence can own

Quite a lot, and this is where Michigan's narrow definition pays off. A non-licensee may own the building, the equipment, the laser platforms, the brand, the customer database, the software, and the entire non-clinical staff, and may own a management services organisation that provides all of it to the practice for a fee. They may also own an esthetics-only business outright — the services within MCL 339.1210, as expanded by Public Act 160 of 2024, involve no learned profession and need no professional entity. Many Michigan operators are better served by that model than by a medical one they cannot own.

The nonprofit exception under OAG No. 6770

Michigan recognises one clean exception, narrower than it sounds. In OAG No. 6770 (September 17, 1993) the Attorney General concluded that hospitals and other nonprofit corporations organised under the Nonprofit Corporation Act, 1982 PA 162, may provide medical services through employed physicians — the learned-profession rule exists to stop laypersons commercialising medicine, a risk thought absent where no shareholder profits. That reasoning is also the boundary: it does nothing for a for-profit med spa.

Can a Nurse Practitioner Own a Med Spa in Michigan?

Michigan is one of the few states where this question has no confident answer, and anyone who gives you one has not read the entity statutes. The uncertainty is not about nursing scope — it is about a list nursing was never put on.

Why Michigan's APRN prescribing authority raises the question at all

Michigan is classified as a reduced practice state, yet the specific authority an aesthetics practice needs sits with the APRN. Under MCL 333.17211a, following 2016 PA 499 effective April 9, 2017, an advanced practice registered nurse may prescribe nonscheduled prescription drugs in their own name — and botulinum toxin and dermal fillers are nonscheduled. A Michigan APRN can evaluate, order and inject without any physician delegating the act. Clinically the practice runs. The question is what entity it runs inside.

Nursing is not an enumerated professional service

Here is the statutory gap. The professional service definitions at MCL 450.1282 and MCL 450.4902 list public accountants, chiropractors, dentists, optometrists, veterinarians, osteopathic physicians, physicians, surgeons, podiatrists, chiropodists, physician assistants, architects, engineers, land surveyors and attorneys. Nurses are absent. Two consequences follow, cutting opposite ways: an APRN cannot hold shares in a corporation formed to practise medicine — but neither is an APRN-only practice obviously required to take professional form, because nursing is not a learned profession under MCL 450.1109.

Where the APRN-owned model quietly breaks

The defensible reading is an ordinary Michigan LLC, owned by the APRN, rendering nursing services within APRN scope, with no physician equity and no physician-delegated acts. Nothing forbids it and no reported Michigan decision or Attorney General opinion addresses it squarely — which is why it is a reading and not a rule. Two things break it. Scope creep: the moment the clinic offers something only a physician may order, the entity is rendering medicine. And delegation, since whether an APRN may be the delegating provider for a non-prescriber injector is itself unsettled here. Our national nurse practitioner med spa ownership playbook sets Michigan beside the states that answered by statute. Get written Michigan advice before you file.

RN, PA, Esthetician, and Pure-Investor Ownership

The remaining categories resolve faster, mostly because the statute either names them or conspicuously does not.

Registered nurses and LPNs

Verdict: the same statutory gap, with less to stand on. An RN faces the identical absence from the professional service list, so the same argument is available. What an RN lacks is the prescribing authority that makes the APRN version coherent. An RN-owned med spa still needs a prescriber to evaluate patients and order product, and that prescriber sits outside the ownership structure — the arrangement a regulator reads as a licensee lending authority to a business they do not control.

Physician assistants

Verdict: yes, but only with a physician. PAs are on the professional service list, and the statute expressly permits physicians to organise a professional corporation or PLLC with one or more physician assistants. The limit is equally express: an entity whose only members are physician assistants is not permitted. A PA can be a genuine co-owner of a Michigan medical practice — a real advantage over most states — provided a physician owner is in the structure.

Estheticians, cosmetologists, and the pure investor

Verdict: full ownership of the non-medical business, none of the medical one. Esthetics and cosmetology are licensed under Article 12 of the Occupational Code, a different statute from the Public Health Code, and those services are not medicine — so an esthetician may own their spa outright with no professional entity. The pure investor lands in the same place by another route: no licence, no shares in the practice, and a management company as the only lawful path to a return.

MSO and Management Structures — and Where They Tip Into Unlawful Control

Every Michigan med spa funded by someone who cannot hold shares ends up here. The management services organisation is a legitimate structure the state has never prohibited — and the one the Michigan State Medical Society has asked the Attorney General to examine.

The two entities

The clinical entity is a PC or PLLC owned by a physician, which employs or contracts the clinical staff, holds the patient records, bills for professional services, and owns every clinical decision. The MSO is an ordinary Michigan LLC owned by whoever has the capital; it holds the lease, the equipment, the brand and the non-clinical staff, supplied under a written management services agreement for a fee. Both entities are real and keep their own books — and the moment they stop behaving as two, the separation stops protecting anyone.

What the MSO can legitimately do

A great deal, and understating this leads people to build structures that cannot function. The MSO may own and maintain the premises and devices, employ receptionists, coordinators, marketers and administrators, run scheduling, purchasing, payroll, IT and bookkeeping, handle advertising, negotiate vendor contracts, and supply financial reporting. None of that is the practice of medicine. A well-drafted Michigan management agreement is long precisely because it enumerates these services rather than gesturing at management in the abstract.

Where an MSO tips into unlawful control

The tipping points are consistent, and they concern clinical authority rather than money. The MSO must not select or veto treatments, write or approve clinical protocols, set per-provider quotas, hire or fire clinical staff on clinical grounds, control the records, or decide the standard of care. Two features draw the sharpest scrutiny: a physician owner compensated as a figurehead rather than practising, and a stock transfer restriction agreement letting the MSO move the practice equity to a successor physician of its choosing. That combination is what MSMS and several specialty societies described in their October 23, 2023 letter to the Attorney General as ownership in name only.

Getting the management fee right

The fee is where a defensible structure most often goes wrong on paper. Fair market value, set in advance, documented, and not varying with the volume or value of referrals is the standard to design to. A percentage-of-collections fee is common in the market and the highest-risk formulation in Michigan, because it is most easily characterised as dividing a professional fee. A fixed or valuation-supported fee, revisited as the practice grows, is far easier to defend.

Fee-Splitting and Kickback Exposure in Michigan

Michigan attacks fee splitting from three separate statutes, and med spa owners routinely meet the criminal ones only after signing something. None requires a harmed patient.

MCL 750.428 and the criminal fee-division rule

The Michigan Penal Code makes it a misdemeanour for a physician or surgeon to divide fees with, promise part of a fee to, or pay a commission to another physician, surgeon or person who calls them in consultation or sends them patients for treatment or operation. The penalty is up to six months and a fine of up to $750 — small money, and beside the point, because a conviction reaches the licence: the board may revoke on a first conviction and must revoke on a subsequent one. Any med spa paying a per-patient referral incentive should read that twice.

MCL 333.16221 and the Health Care False Claim Act

On the licensing side, MCL 333.16221 makes unethical business practices grounds for discipline, and those expressly include dividing fees for the referral of patients and accepting kickbacks on services, appliances or medications purchased by or on behalf of patients. Separately, the Health Care False Claim Act at MCL 752.1004 makes soliciting, offering, paying or receiving a kickback or bribe a felony carrying up to four years or a $50,000 fine where an insurer pays. Cash-pay aesthetics narrows that statute without eliminating it.

Where med spas actually trip it

The recurring patterns are mundane. Paying staff or partners a percentage of treatment revenue they referred. Revenue-sharing with a landlord who sends clients upstairs. Management fees calculated as a share of professional collections. Affiliate programmes priced per booked treatment. Each would be unremarkable in retail, and each maps onto conduct three Michigan statutes describe. The fix is the same every time: pay for work performed at a rate set in advance.

Miller v Allstate and the Enforcement Gap Michigan Owners Misread

This is the case behind every claim that Michigan does not really enforce the corporate practice of medicine. It is a real holding with real consequences, and it protects less than people assume.

What the Michigan Supreme Court actually held

In Miller v Allstate Ins Co, 481 Mich 601 (2008), an insurer resisted paying for physical therapy on the ground that the provider had incorporated as an ordinary business corporation when it should have used professional form. The Michigan Supreme Court held that the Business Corporation Act creates an irrebuttable presumption of proper incorporation once articles are properly filed, and that only the Attorney General has standing to challenge a corporation's status. That removed the private-litigant challenge which polices the corporate practice rule elsewhere.

Why it is not the safe harbour it sounds like

Miller says who may attack the entity. It says nothing about the exposures that actually end med spa businesses. LARA and the disciplinary subcommittees can still act against the licensee under MCL 333.16221 however the corporation was filed. The unlicensed practice felony at MCL 333.16294 reaches an individual, not a charter. Fee-splitting statutes operate independently, management agreements can still be unenforceable, and a buyer's counsel will still find the defect in diligence. The one party Miller left with standing is the Attorney General — the office MSMS petitioned in 2023, with no publicly announced determination as of August 2026.

Where the Medical Director Fits in a Michigan Ownership Structure

Michigan has no med spa statute and no rule using the term medical director, yet the role is unavoidable in substance — and conflating it with ownership is one of the most common structural errors in the state.

When a physician is genuinely required

A physician is required whenever the clinic performs acts only a physician may perform or delegate. Under MCL 333.16215 a licensee may delegate an act to a licensed or unlicensed individual qualified by education, training or experience, within the delegator's own scope and under the supervision definition at MCL 333.16109. There is also a device rule: MCL 333.16276 bars a laser procedure for dermatological purposes except under physician supervision, with the patient's knowledge and consent.

Owner authority and clinical authority are different things

A medical director who owns no equity is normal and lawful; a director who owns the equity on paper while someone else runs the practice is the pattern regulators look for. Write the agreement so the clinical authority is real — the director sets protocols, approves the service menu, assesses delegatee competency, and can stop a treatment or a hire on clinical grounds. Our complete guide to the med spa medical director covers the duties behind the title, and the med spa regulations by state reference shows how Michigan's neighbours differ.

What Happens If a Michigan Med Spa Is Structured Wrong

Michigan rarely dissolves a defective entity. What it does instead is slower and generally more expensive, because the consequences land on people rather than on the corporate charter.

Exposure for the licensee inside the structure

The physician or APRN carries the licensing risk personally. MCL 333.16221 supplies the grounds — unethical business practices, negligent delegation and supervision whether or not injury results — and MCL 333.16226 supplies sanctions from fines and probation through suspension to revocation. A physician who lent their name to an entity they did not direct has no good answer when asked to describe their clinical role.

Exposure for the lay owner

A non-licensee who directs clinical decisions is not merely in breach of a corporate statute. Practising, or holding oneself out as practising, a health profession without a licence is a felony under MCL 333.16294, and control over treatment selection, protocols and clinical staffing is the evidence of practising. Miller does not help: nothing in it prevents an individual being charged for what they personally did.

Contract, insurance, and transaction fallout

The commercial consequences usually arrive first. A management agreement that splits professional fees may be void or unenforceable, which becomes a problem the day the parties fall out. Professional liability policies commonly exclude services not lawfully rendered, so a structural defect can be both the reason a claim exists and the reason it is uncovered. And every acquirer of aesthetics practices now runs corporate-practice diligence as standard — a defective entity or a percentage-of-collections fee reliably reprices a deal.

A Decision Framework by Your Own Licence

Strip the theory away and Michigan ownership resolves into four starting positions. Find yours, then take the corresponding first step.

If you are a physician (MD or DO)

You have the clearest path in the state. Form a PC or PLLC stating the practice of medicine as its purpose, hold the shares yourself or through a qualifying holding entity, and add a PA, podiatrist or chiropractor co-owner only where a statute names that combination. Put the transfer restrictions in place at formation, and if outside capital is coming, structure it as an MSO from the start.

If you are an APRN

You can run the clinical side of a Michigan aesthetics practice on your own prescribing authority; the entity question is the open one. Do not take shares in a medicine PC — you are not eligible. Get written Michigan advice on whether an APRN-owned ordinary entity fits your specific menu, scope that menu so nothing on it requires a physician order, and revisit the analysis each time you add a service.

If you are an RN, PA, or esthetician

A PA can co-own with a physician and should simply do that. An RN faces the APRN analysis without the prescribing authority that makes it work, so co-ownership or employment with a physician-owned practice is the realistic route. An esthetician can own an esthetics business outright — the cleanest position of the three, provided the menu stays inside MCL 339.1210.

If you hold no health care licence

Own the MSO, not the practice. Recruit a physician owner who will genuinely practise and genuinely direct clinical care, paper the management agreement in detail with a fixed or valuation-supported fee, and resist every temptation to reserve clinical control — that reservation is the single fact most likely to make a lawful structure unlawful. If you would rather not draft the agreements and oversight documentation from scratch, our library of ready-to-use med spa compliance SOPs covers the paperwork a compliant Michigan structure has to produce.

This article is for informational purposes only and does not constitute legal advice. Michigan entity, licensing and fee-splitting requirements are administered by LARA and the Michigan Board of Medicine and change over time. Several points here — APRN and RN ownership of a non-professional entity, the treatment of management fees, and the scope of any Attorney General review of ownership in name only — are genuinely unsettled. Confirm current requirements with the relevant agency and consult a Michigan healthcare attorney before choosing or changing an ownership structure.
