Massachusetts CPOM Rules 2026: Who Can Own a Practice

Massachusetts enforces a strong corporate practice of medicine (CPOM) rule, and unlike most states it is written down. The Board of Registration in Medicine's regulations list the entities physicians may practice through: professional corporations, qualifying LLCs and partnerships, nonprofits, and licensed health care facilities. General business corporations are not on the list. As of October 2026, a non-physician founder should plan on a friendly PC-MSO structure, and should expect more state attention to investor-backed deals after a 2025 market review law brought significant equity investors into the Health Policy Commission's notice process. NP founders have a real option: Massachusetts granted nurse practitioners full practice authority in 2021, after a period of supervised practice. PA founders still need physician involvement.

Key takeaways

The Massachusetts Board of Registration in Medicine's regulations at 243 CMR 2.07 list the business forms physicians may practice through, and general business corporations are not among them.
Massachusetts courts have long held that a licensed professional may not practice as the servant of an unlicensed person or corporation, a principle commentators trace to McMurdo v. Getter.
Physicians may practice as employees of licensed health care facilities, which is the main route for lay-controlled employment.
An Act Enhancing the Market Review Process, signed in January 2025, expanded Health Policy Commission material change notices to cover transactions involving significant equity investors.
Massachusetts nurse practitioners gained full practice authority in January 2021, after completing a period of supervised practice.

Does Massachusetts have a corporate practice of medicine doctrine?

Yes, and it has two layers.

Case law. Massachusetts courts have long held that a licensed professional may not practice as the servant of an unlicensed person or a corporation. Commentators cite McMurdo v. Getter for the principle and describe its concern as divided loyalty: a physician employed by a business may serve the employer's interests before the patient's.

Board regulation. In 2012 the Board finalized rules that put the doctrine in writing. Under 243 CMR 2.07, physicians may practice through:

a professional corporation organized under M.G.L. c. 156A,
a nonprofit organization, including hospital and medical service corporations,
an LLC organized under M.G.L. c. 156C, as long as the operating terms do not limit the physician's liability for their own negligence or intentional torts,
a partnership, or
a similar entity organized outside Massachusetts.

As Mintz noted when the rules were finalized, an early draft allowed general business corporations, and the final rule dropped them. That omission is the core of the Massachusetts rule. A Massachusetts health law overview from Hooper Lundy adds that the restrictions do not stop a physician from working as an employee of a licensed health care facility.

Who can own a medical practice in Massachusetts?

Licensed professionals own the professional entity. Under chapter 156A, a professional corporation exists to render professional services, and the Secretary of the Commonwealth's rules in 950 CMR 105.00 say chapter 156A controls when it conflicts with the general corporation statute. A professional corporation can merge only with entities whose shareholders are all licensed to render the relevant service.

Exceptions run through the nonprofit and facility routes. Hospitals, nonprofit organizations and licensed health care facilities can employ physicians. A for-profit investor, by contrast, cannot hold equity in a medical PC.

Can nurse practitioners and physician assistants own a practice in Massachusetts?

Nurse practitioners. Massachusetts made NP full practice authority permanent through legislation effective January 1, 2021, and the Board of Registration in Nursing finished its implementing rules in 2021. An NP must first complete a period of supervised practice under a physician before practicing independently. Sources differ on how that period is measured, so confirm it with the Board of Registration in Nursing. After that, an NP can open an independent practice. Massachusetts commentators describe ownership of medical practices as limited to licensed physicians and certain nurse practitioners. Whether an NP can co-own a medical professional corporation with physicians is a question for Massachusetts counsel.

Physician assistants. PAs did not get the same independence. Plan on a supervising physician arrangement and a physician-owned entity for a PA-staffed clinic. See our guide to the collaborating physician role.

How does the friendly PC-MSO model work in Massachusetts?

The friendly PC-MSO model is the standard path: a Massachusetts-licensed physician owns a chapter 156A professional corporation, and your company's MSO provides non-clinical services under a management services agreement. Clinical decisions stay with licensed providers.

Two Massachusetts features shape the deal.

Fee splitting and profit sharing. Massachusetts law and Board rules restrict fee splitting and payments tied to referrals. Massachusetts practitioners warn against MSA terms that amount to the lay company sharing in the profits of the physician's practice. A percentage-of-revenue fee paid to the MSO invites that question. A flat or cost-plus fee tied to documented services is easier to defend. See our management services agreement guide.

The 2025 market review law. An Act Enhancing the Market Review Process (H.5159) was signed in January 2025. As summarized by Ropes & Gray and McGuireWoods, it:

adds transactions involving "significant equity investors," including private equity, to the Health Policy Commission's material change notice process,
defines management services organizations, mainly to identify investors with a financial interest in providers or MSOs,
lets the Commission request detailed investor financial and ownership information, and
left out earlier Senate proposals that would have restricted MSOs directly.

Several firms read the law so that an investment solely in an MSO may not need notice unless the MSO is also a "provider organization." A small founder-funded MSO may be outside its reach. A venture-backed or PE-backed brand should run the analysis before any transaction.

What does this mean for a telehealth brand serving Massachusetts patients?

CPOM follows the patient. If your clinicians treat people located in Massachusetts, Massachusetts rules apply wherever your company sits.

Massachusetts has no out-of-state telehealth registration. Every physician, NP and PA treating Massachusetts patients needs a Massachusetts license. Our telehealth licensing by state guide compares states.

A practical setup: a physician-owned 156A professional corporation, Massachusetts-licensed NPs and PAs inside it, and a flat-fee MSA. If your investors include private equity, add a material change notice review to your diligence list. Neighboring guides: New Hampshire, New York, Connecticut.

Frequently asked questions

Can a non-physician own a medical practice in Massachusetts?

Not directly. Board of Registration in Medicine regulations limit physicians to professional corporations, qualifying LLCs and partnerships, nonprofits and licensed facilities. A non-physician can own the MSO that manages a physician-owned practice.

Can a Massachusetts physician work for a business corporation?

Generally not, unless the employer is a licensed health care facility. The Board's 2012 rules left general business corporations off the list of permitted practice entities.

Does the 2025 Massachusetts market review law apply to MSOs?

It can. The law brought significant equity investors, including private equity, into the Health Policy Commission's material change notice process and defined MSOs. Whether a particular MSO deal must be reported depends on the structure, so have Massachusetts counsel review it.

Can a nurse practitioner own a practice in Massachusetts?

Yes, after completing the required period of supervised practice. Massachusetts granted NPs full practice authority in 2021. Co-owning a medical professional corporation with physicians is a separate question for counsel.

Can out-of-state clinicians treat Massachusetts patients by telehealth?

Only with a Massachusetts license. Massachusetts has no out-of-state telehealth registration, so plan on full licensure for each physician, NP and PA.
