Maryland presents a compliance puzzle that is, in some ways, harder to solve than states with clear CPOM statutes. When a state like Michigan puts its prohibition in black-letter law, you know exactly what you are dealing with. When a state like Maryland assembles its doctrine from professional corporation provisions, Board guidance, and Attorney General opinions — with no single controlling statute — compliance requires a different kind of analysis. The Baltimore-DC health technology corridor is home to a growing number of digital health companies, telehealth startups, and healthcare IT ventures, and many of them underestimate Maryland's CPOM exposure precisely because the prohibition is not written in the obvious places. This guide explains what Maryland's CPOM doctrine actually says, how the Maryland Board of Physicians interprets it, and how to build a structure that holds up.

Why Maryland's CPOM Framework Is Different

Most strong CPOM states have some version of a statute that says corporations cannot practice medicine or that the practice of medicine is restricted to licensed individuals. California has Business and Professions Code §2400. Michigan has its Public Health Code. Texas has the Texas Medical Practice Act. Maryland does not have an equivalent provision. The absence of a single prohibitory statute creates the ambiguity that characterizes Maryland CPOM analysis.

What Maryland does have is a comprehensive professional corporation framework in Health General Article §14-401 et seq., which establishes that corporations rendering health professional services must be owned by licensed health professionals. This provision accomplishes a CPOM-equivalent result through entity structure requirements rather than through a direct prohibition. The Board of Physicians interprets this framework as establishing the limits of permissible corporate employment of physicians, and Attorney General opinions have confirmed that the framework effectively prohibits lay corporate control of medical practices.

The practical consequence of Maryland's structural approach to CPOM is that compliance analysis is heavily dependent on how the Board of Physicians interprets specific arrangements at any given time. A broad, bright-line statute like California's leaves less room for the Board to take positions that surprise careful planners. Maryland's framework, by contrast, gives the Board interpretive authority that it has exercised in ways that are not always predictable. Founders need to treat Maryland as a state where the rules can shift with Board personnel, Attorney General opinion changes, and evolving regulatory priorities — even if the underlying statutes do not change.

The Statutory Framework: Health General Article §14-401 et seq.

Maryland's professional corporation provisions are contained in the Health General Article (Md. Code Ann., Health-Gen. §14-401 et seq.). These provisions establish that a professional service corporation providing health professional services must be organized, owned, and controlled by individuals who are licensed to render those services. For medical professional corporations, this means physician ownership is required.

Health General Article §14-404 specifies the requirements for professional corporations: the corporation must be organized solely for the purpose of rendering professional services, all shareholders must be licensed professionals authorized to render those services, and the corporation must maintain a licensed practitioner as its responsible agent for purposes of professional regulation. Non-professionals may not own shares in a Maryland medical professional corporation.

The statute also specifies permissible corporate forms: Maryland allows both professional corporations (PCs) and professional limited liability companies (PLLCs) for physician-owned entities. In practice, both forms are used. The PLLC has become increasingly common because of its governance flexibility and pass-through tax treatment, but both forms satisfy Maryland's ownership requirements.

The Role of the Maryland Board of Physicians

The Maryland Board of Physicians is the primary enforcement body for CPOM-related violations in Maryland. The Board's enforcement authority derives from Md. Code Ann., Health Occ. §14-101 et seq., which grants the Board broad power to discipline licensed physicians for unprofessional conduct, including participation in non-compliant corporate arrangements.

The Board's approach to CPOM enforcement is notably interpretation-driven. Unlike states with bright-line statutory rules, Maryland's Board has issued guidance through policy statements and informal communications that attempt to define the line between permissible and impermissible corporate arrangements. This guidance has the practical effect of law for Maryland founders, even though it does not carry the formal weight of statute or regulation.

Maryland's CPOM doctrine lives in the space between statute and Board policy. That space gives well-counseled founders flexibility — but it also gives the Board unpredictability. In Maryland, the quality of your legal counsel and the robustness of your structural documentation matter more than in most other states.

The Board has been clear on one important point: the three categories of entities that may employ physicians in Maryland are professional service corporations, licensed hospitals and health facilities, and licensed HMOs. An investor-backed technology company that does not fit into one of these categories cannot directly employ physicians for clinical service delivery. This position is not just the Board's preference — it is grounded in the Health General Article's ownership requirements and has been confirmed by Attorney General opinion.

Attorney General Opinions and Their Significance

Maryland's Office of the Attorney General has issued several opinions that bear directly on CPOM compliance, and these opinions carry significant weight in Maryland regulatory practice even though they are not formal law. AG opinions addressing the corporate practice of medicine have consistently reinforced the Board of Physicians' position that lay corporate ownership of medical practices is impermissible, and they have addressed specific structural variations — including management company relationships — with varying degrees of specificity.

The importance of AG opinions for Maryland CPOM compliance cannot be overstated. When the Board of Physicians takes an enforcement action or denies a registration, it frequently cites AG opinions as authority. Courts reviewing Board actions defer substantially to AG opinions as interpretations of state law. And investors and acquirers conducting due diligence in Maryland will ask about AG opinion analysis of your structure.

Founders should ensure that their Maryland healthcare counsel has specifically reviewed relevant AG opinions as part of the structural analysis — not just the statutory text, and not just the Board's public guidance.

Permitted Employer Categories: The Three Safe Harbors

Maryland's Board of Physicians has identified three categories of entities that may employ physicians to deliver clinical services:

Professional Service Corporations and PLLCs

Physician-owned professional service corporations and PLLCs organized under Maryland law are the primary vehicle for compliant clinical entity structures. These entities must satisfy Health General Article §14-404's ownership requirements — licensed physicians holding all equity — and must operate with physician control over clinical governance. For digital health founders, this is the clinical entity that sits at the top of the MSO-PC structure.

Licensed Hospitals and Healthcare Facilities

Maryland licensed hospitals and licensed healthcare facilities (including ambulatory surgical centers and certain outpatient facilities licensed by the Maryland Health Care Commission) may employ physicians as part of their licensed operations. This exception reflects the reality of the hospital employment market in Maryland, which has one of the highest rates of hospital physician employment in the country — driven by the dominance of large health systems like Johns Hopkins, University of Maryland Medical System, and Medstar Health.

This exception is not available to digital health startups unless they are organized as and licensed as a healthcare facility under Maryland law — which is a separate, substantial regulatory undertaking.

Licensed HMOs

Maryland-licensed Health Maintenance Organizations may employ physicians as part of their integrated care delivery operations. Like the hospital exception, this is not available to investor-backed technology companies that have not obtained HMO licensure.

The MSO-PC Structure in Maryland

For investor-backed digital health companies, the MSO-PC structure is the only viable path to compliant Maryland operations. Maryland's version of the MSO-PC structure works the same way as in other states, but with greater emphasis on documentation quality and physician governance substance — because Maryland's interpretation-dependent CPOM framework means the Board will look more carefully at whether the actual operation of the arrangement reflects genuine physician independence.

Structural Requirements for the Maryland PC

The Maryland professional corporation or PLLC must be 100% physician-owned and must maintain genuine physician control over all clinical governance. The articles of incorporation or operating agreement should explicitly vest clinical authority in the physician owners: authority over clinical protocols, authority to hire and terminate clinical staff, authority to set standards of care, and authority to accept or reject patients.

Maryland healthcare attorneys generally recommend that the Maryland PC maintain written clinical governance policies that are adopted by the physician owners in documented meetings — not policies that are handed to the PC by the MSO for pro forma adoption. The Board will look at whether the PC's clinical governance is substantively physician-driven, and documentation of genuine physician deliberation is the best evidence that it is.

The Management Services Agreement in Maryland

The MSA in Maryland should be drafted conservatively given the interpretive uncertainty of the CPOM doctrine. Provisions to treat with particular care in Maryland MSAs:

Baltimore and the DC Corridor: Market-Specific Considerations

The Baltimore-Washington, DC corridor is one of the densest healthcare markets in the country, home to major federal health agencies (NIH, FDA, CMS, HRSA), a concentration of academic medical centers, and a growing health technology startup ecosystem. Several features of this market are relevant to CPOM compliance planning:

Federal contractor presence. Many Maryland health technology companies do significant business with federal agencies. Federal contracting relationships create their own compliance frameworks, and CPOM violations that surface in the context of federal contracting can have consequences beyond Maryland state enforcement — including False Claims Act exposure if federal program funds are involved in a non-compliant arrangement.

Health system dominance. Maryland's healthcare market is dominated by large health systems that have both political influence with the Board of Physicians and competitive reasons to challenge non-traditional care delivery models. Digital health companies entering Maryland markets should anticipate that established health systems may scrutinize their corporate structures.

Mental health and behavioral health growth. Maryland has seen significant expansion of telehealth-delivered mental health services, driven by both demand and Maryland's relatively favorable parity law for behavioral health coverage. Behavioral health companies operating in Maryland need to be aware that Maryland has separate professional practice acts for psychologists and social workers, each with their own corporate practice implications.

Telehealth in Maryland

Maryland has a robust telehealth framework, with insurance coverage parity requirements that apply to most telehealth services. Maryland participates in the Interstate Medical Licensure Compact (IMLC), making multi-state physician credentialing more manageable for telehealth companies treating Maryland patients from outside the state.

For out-of-state telehealth companies treating Maryland patients, the CPOM compliance question is the same as for in-state companies: the clinical entity employing your physicians must satisfy Maryland's professional corporation requirements if it is regularly delivering services to Maryland patients. The Board of Physicians evaluates jurisdiction based on where the patient is located, not where the company is incorporated or where the physician holds primary licensure.

Practical Compliance Steps for Maryland Founders

  1. Form a Maryland professional corporation or PLLC under Health General Article §14-401 et seq. with 100% physician ownership. Do not use a general LLC or standard corporation for the clinical entity.
  2. Commission a formal AG opinion review from Maryland healthcare counsel covering your specific MSO-PC structure before launch. Given Maryland's interpretation-dependent framework, a generic structural analysis is insufficient.
  3. Draft the MSA with conservative clinical independence provisions. Maryland's ambiguous doctrine means the MSA's clinical governance language will receive more scrutiny than in states with clearer rules.
  4. Hold substantive documented physician governance. In Maryland especially, nominal physician governance is not enough. Board meeting minutes, written clinical policy adoptions, and evidence of actual physician deliberation are the paper trail that protects the structure.
  5. Structure management fees with a documented FMV basis. A third-party valuation of the management services is a strong protective measure in Maryland given the Board's interpretive discretion.
  6. Ensure Maryland licensure or IMLC coverage for all physicians treating Maryland patients.
  7. Build structural review into your fundraising and M&A processes. Maryland CPOM ambiguity is a known due diligence issue — proactively addressing it reduces transaction friction.
