Michigan has some of the most firmly established corporate practice of medicine restrictions in the Midwest, and its statutory framework is unusually explicit compared to states where the doctrine derives primarily from court opinions or regulatory guidance. For digital health founders eyeing the Detroit-Ann Arbor health technology corridor — or for out-of-state telehealth platforms treating Michigan patients — understanding Michigan's CPOM rules is non-negotiable before a single clinical encounter occurs. This guide covers the statutory basis for Michigan's CPOM doctrine, the enforcement framework, the MSO-PC structure requirements, and the compliance steps that matter most for founders.

The Statutory Basis: Michigan Public Health Code and Professional Corporation Act

Michigan's CPOM restrictions draw from two main statutes, and both are worth understanding because they operate in slightly different ways.

The Michigan Public Health Code (MCL 333.1101 et seq.) is the comprehensive statute governing licensed health professions in Michigan. Article 15 of the Public Health Code governs health professions and includes specific provisions about who may practice medicine and under what conditions. The Code prohibits the unlicensed practice of medicine and, through a combination of provisions, establishes that controlling or profiting from the practice of medicine is the functional equivalent of practicing medicine — making it illegal for unlicensed persons or entities to do so. The Michigan Board of Medicine derives its authority from the Public Health Code, and it is the Board's enforcement that gives these provisions their practical bite.

The Michigan Professional Corporation Act (MCL 450.221 et seq.) is the specific statute that governs physician-owned professional entities. This Act requires that any corporation organized to render professional services in Michigan — including medical services — be incorporated by and owned exclusively by persons licensed to render those professional services. For medicine, this means shareholders must be Michigan-licensed physicians. The Act does not permit minority ownership positions for non-physicians, PAs, or other allied health professionals, unlike some other states.

The combined effect of these two statutes is one of the clearest CPOM regimes in the country. Michigan does not leave founders to infer the prohibition from general licensure requirements or scattered administrative guidance — the statutes say what they say, and the Michigan Board of Medicine takes them seriously.

Statutory Exceptions: What They Cover and What They Don't

Michigan is one of the few states that explicitly codifies exceptions to its CPOM prohibition, rather than leaving exceptions to be defined through regulatory guidance or individual negotiations with the Board. The three main recognized exceptions are meaningful, but none of them create an opening for venture-backed digital health companies:

Licensed Hospitals

Michigan allows licensed hospitals to employ physicians directly, even though hospitals are not physician-owned professional entities. This exception reflects the reality that the hospital employment model has been the dominant form of physician employment in Michigan since at least the 1990s. Hospital employment does not require the MSO-PC structure — a licensed Michigan hospital can hire physicians as employees directly. However, this exception is limited to licensed hospitals. Health technology companies or startups cannot claim this exception, even if they have a partnership or contract with a hospital.

Nonprofit Foundations

Michigan recognizes that certain nonprofit foundations — particularly those affiliated with academic medical centers or established health systems — may employ physicians in ways that would otherwise raise CPOM concerns. This exception is narrowly construed and does not extend to for-profit entities or to nonprofits formed primarily to circumvent CPOM rules. A startup that creates a nonprofit affiliate and routes physician employment through it would face serious scrutiny about whether the arrangement is a genuine nonprofit operation or a CPOM workaround.

Licensed HMOs

Health Maintenance Organizations licensed under the Michigan HMO Act may employ physicians as part of their integrated care delivery model. This exception acknowledges the long history of staff-model HMOs in Michigan and the state's significant HMO marketplace. It does not extend to general health insurers, benefit managers, or companies that offer health services without an HMO license.

Michigan's exceptions are real and operationally important — but none of them were designed for digital health startups, and none of them can be reasonably stretched to cover an investor-backed telehealth company. For founders, the MSO-PC structure is the only viable path to compliance in Michigan.

The Michigan Board of Medicine's Enforcement Approach

The Michigan Board of Medicine enforces the Public Health Code's restrictions on physician practice through formal administrative proceedings. The Board's enforcement is reactive in the same way as most state medical boards — it primarily responds to complaints — but Michigan's Board is known for substantive follow-through when complaints reveal structural issues.

Enforcement risk for digital health companies in Michigan is most acute in three situations. First, when a clinical adverse event triggers an investigation that exposes the underlying corporate structure. Second, when a corporate transaction (acquisition, investment, or restructuring) brings external scrutiny that surfaces compliance problems. Third, and increasingly common, when competitors or payers file complaints about non-compliant structures being used by companies they believe are undercutting them in the market.

The consequences the Board can impose on physician participants in non-compliant structures include formal reprimand, probation, license suspension, and license revocation. For the company, the Board can refer matters to the Michigan Attorney General, which can pursue civil or criminal action for the unlicensed practice of medicine. The practical consequence that frightens founders most is contract voiding: management services agreements that are found to effect the corporate practice of medicine can be declared void and unenforceable, which unwinds the MSO-PC financial relationship and leaves both entities without a legal framework for their operations.

The MSO-PC Structure in Michigan

Michigan digital health companies must implement the MSO-PC model correctly and specifically. Michigan is more explicit than many states about one particular structural requirement: clinical employees must be employed by the PC, not the MSO. This is a point where many startup founders make mistakes, and in Michigan it is a clear statutory violation, not a gray area.

The Michigan Professional Corporation

The Michigan PC is formed under the Professional Corporation Act and must have a name that includes the designation "PC," "Professional Corporation," or an equivalent. All shareholders must be Michigan-licensed physicians — no exceptions, no PA or NP minority shareholders permitted under Michigan law. The PC is the entity that holds the medical practice, bills for clinical services, and contracts with payers.

The PC must employ or contract directly with all clinical personnel: physicians, physician assistants, nurse practitioners, medical assistants, and any other staff who deliver clinical care. This employment must be genuine — the PC must actually control the terms and conditions of clinical employment, including compensation, termination authority, and clinical supervision. If the MSO sets the terms of clinical employment and the PC simply ratifies them, Michigan regulators and courts would look through that arrangement and find that the MSO is effectively the employer.

The Investor-Owned MSO

The MSO provides the PC with non-clinical services under a Management Services Agreement. In Michigan, the importance of scrupulously non-clinical MSO functions is heightened by the statutory clarity of the CPOM prohibition. The MSO cannot employ clinical staff, it cannot set clinical protocols, it cannot control physician scheduling for clinical reasons, and it cannot make decisions about clinical quality or patient safety. These functions belong exclusively to the PC and its physician governance.

The MSO can employ non-clinical staff — marketing personnel, software engineers, billing coders, administrative coordinators, customer support staff, and similar roles. The MSA should enumerate these functions explicitly and should include affirmative representations that the MSO will not exercise control over clinical operations.

Employment Structure and the Clinical/Non-Clinical Line

One practical complication that Michigan's structure creates for digital health founders is the treatment of dual-role employees. A person who both writes clinical protocols (clinical function) and manages provider onboarding (administrative function) may need to be employed by the PC rather than the MSO, even though much of their day-to-day work looks administrative. Michigan's conservatism on this issue means founders should err on the side of PC employment for any role with a clinical dimension, and should consult Michigan healthcare counsel specifically about roles that do not fit neatly into one category.

Telehealth in Michigan: A Complex Regulatory Landscape

Michigan has historically had a more complex telehealth regulatory environment than progressive states like Colorado or Washington. Michigan's telehealth rules have evolved significantly since 2020, and the state now has more favorable coverage requirements for telehealth services, but navigating the specific payer-by-payer rules requires attention.

For CPOM purposes, the relevant Michigan telehealth rule is this: if a physician delivers clinical services to a patient located in Michigan via telehealth, that physician is practicing medicine in Michigan and the corporate structure employing that physician must comply with Michigan's CPOM requirements. An out-of-state telehealth company treating Michigan patients must have a Michigan-compliant PC structure — registering a foreign PC in Michigan and ensuring it meets Michigan's physician-ownership rules — or it faces exposure under the Public Health Code.

Michigan is a member of the Interstate Medical Licensure Compact (IMLC), which simplifies multi-state physician licensing. For telehealth companies building networks of clinicians who treat Michigan patients, IMLC membership substantially reduces the credentialing burden.

The Ann Arbor and Detroit Health Tech Ecosystem

Michigan's health technology ecosystem is anchored by the University of Michigan Medical School and Henry Ford Health System in Detroit, which together generate substantial clinical research activity, physician talent, and institutional knowledge about how Michigan's regulatory environment works in practice. Ann Arbor in particular has produced a series of digital health companies that have had to navigate Michigan's CPOM framework, and the local healthcare bar has substantial experience advising founders.

Detroit's emergence as a health technology hub — driven partly by investments in health equity and access-focused digital health — has brought additional attention to whether health tech companies operating in urban Michigan markets are complying with CPOM requirements. This market attention is worth noting: urban markets with complex payer mixes and significant health system presence tend to generate more competitive complaints and more regulatory scrutiny than rural markets.

What Makes Michigan Unique

Michigan's CPOM framework is distinctive in several ways that digital health founders need to understand explicitly:

Statutory explicitness. Michigan has written its CPOM restrictions into statute more comprehensively than most states. This means the prohibition is harder to argue around, but it also means the rules are more predictable. A founder who reads the Public Health Code and the Professional Corporation Act will have a clear picture of what is required — there is less need to infer the doctrine from scattered case law.

Clinical employment specificity. Michigan's requirement that clinical employees be employed by the PC — not the MSO — is more explicit than in many other states. This requirement has direct consequences for how you structure employment contracts, payroll, benefits administration, and supervision for your clinical workforce.

Named statutory exceptions. Unlike states where exceptions to CPOM are determined case-by-case or through informal Board guidance, Michigan's exceptions are in statute. This predictability is a compliance advantage — you know which structures are categorically acceptable and which are not — but it also means there is less room for creative structuring arguments.

Practical Compliance Steps for Michigan Founders

  1. Form a Michigan Professional Corporation under MCL 450.221 et seq. with 100% physician ownership before any clinical operations begin.
  2. Employ all clinical staff through the PC. Do not employ physicians, PAs, NPs, or other clinical staff through the MSO. This is the single most common structural error in Michigan and it is a clear violation of the Public Health Code.
  3. Draft an MSA that explicitly limits the MSO to non-clinical services and includes affirmative covenants that the MSO will not interfere with clinical governance, clinical hiring, or clinical protocols.
  4. Maintain documented physician governance. Michigan courts and the Board look at actual control. Physician governance that exists only on paper will not protect the structure.
  5. Structure management fees as fair market value compensation for enumerated non-clinical services. Document the valuation basis.
  6. Ensure all treating physicians are Michigan-licensed or IMLC-covered before they treat Michigan patients via telehealth.
  7. Consult Michigan healthcare counsel before any capital raise or acquisition that involves due diligence on your corporate structure.
