The MSO-PC structure is the backbone of most healthcare startups founded by non-physicians. If you are building a company that delivers clinical services but you are not a licensed doctor, this dual-entity model is likely how you will need to organize your business. Understanding how it works, and how to set it up correctly, is critical to your long-term success. This model is the primary solution to the Corporate Practice of Medicine (CPOM) doctrine.

What Is an MSO?

A Management Services Organization (MSO) is a business entity that provides administrative, operational, and non-clinical support services to a healthcare practice. The MSO is the entity that the founder or investors typically own. It handles everything that does not involve practicing medicine.

Common services an MSO provides include:

The MSO can be structured as an LLC, C-Corp, or any other standard business entity. It is not restricted by medical practice laws because it does not practice medicine.

What Is a Professional Corporation (PC)?

A Professional Corporation is a special type of corporate entity that exists in most states specifically for licensed professionals, including physicians, dentists, psychologists, and in some states, nurse practitioners. The PC is the entity that holds the medical practice and employs or contracts with the clinicians who deliver patient care. For more on this, see our guide on healthcare entity formation.

The PC is the entity that holds the medical practice and employs or contracts with the clinicians who deliver patient care.

The critical distinction is ownership: the PC must be owned by a licensed healthcare professional authorized to practice medicine in the relevant state. This requirement is what satisfies the Corporate Practice of Medicine (CPOM) doctrine. In some states, the entity may be called a Professional Limited Liability Company (PLLC) instead of a PC, but the concept is the same.

How the MSO and PC Work Together

The magic of the MSO-PC structure lies in how the two entities interact. While the PC owns the clinical practice and employs the providers, the MSO provides all the non-clinical infrastructure the practice needs to operate. This relationship is formalized through a Management Services Agreement (MSA).

Think of it this way: the PC is the medical practice, and the MSO is the business engine that powers it. The MSA is the contract that connects them.

The Management Services Agreement (MSA)

The MSA is arguably the most important document in the entire structure. It defines the specific services the MSO will provide, the fees it will charge, and the boundaries between administrative and clinical functions. A well-drafted MSA should cover:

  1. Scope of services — Detailed description of every administrative service the MSO provides.
  2. Fee structure — How the MSO is compensated, whether through a flat fee, percentage of revenue, or cost-plus model.
  3. Clinical independence — Explicit language preserving the PC's autonomy over all clinical decisions.
  4. Term and termination — Duration of the agreement and conditions for ending it.
  5. Intellectual property — Who owns the technology, brand, and other assets.
  6. Compliance provisions — Requirements for maintaining regulatory compliance.

Ownership Rules and the "Friendly PC" Model

Since the PC must be owned by a licensed physician, non-physician founders typically work with a "friendly physician" who agrees to serve as the PC owner. This physician holds legal ownership of the PC but allows the MSO (and its founder) to manage the business operations. Finding the right physician is key — see our guide on how to find a Friendly PC owner.

The friendly PC arrangement is common and widely accepted, but it must be structured carefully. The physician owner cannot be a figurehead with no real involvement. They must genuinely oversee clinical operations, have authority over hiring and supervising clinicians, and maintain independence in clinical decision-making.

Key ownership considerations include:

Benefits of the MSO-PC Structure

When set up correctly, the MSO-PC model offers significant advantages:

Getting Your MSO-PC Structure Right

The MSO-PC model is powerful, but only when implemented correctly. Poorly structured arrangements can result in regulatory enforcement, loss of medical licenses, voided contracts, and failed fundraising rounds. The details matter: the MSA language, fee structures, physician compensation, and state-specific filing requirements all need to be handled with precision.

Working with advisors who specialize in healthcare corporate structures is not optional. This is one area where cutting corners can have catastrophic consequences for your business.
