What Is an MSO-PC Structure — and Why Does Your Digital Health Startup Need One?

As digital health and telemedicine startups expand into multiple states, they run into a complex and fast-changing legal landscape. One of the most effective and widely used ways to navigate it is the MSO-PC model. But what exactly is it, why is it essential for companies that want to scale — and why does the way you build it matter more in 2026 than it did even a year ago?

This article breaks down the MSO-PC structure, explains why it's the standard model for operating in states with Corporate Practice of Medicine (CPOM) restrictions, and covers what the newest state laws mean for how you design it.

What Is an MSO-PC Structure?

The MSO-PC model separates clinical and non-clinical functions between two entities:

1. Professional Corporation (PC). A physician-owned entity that delivers clinical care. In CPOM states, only licensed physicians may own the clinical entity and control medical decisions.
2. Management Services Organization (MSO). The business entity — typically owned by founders, investors, or a parent company — that provides non-clinical support: administration, technology, HR, billing, marketing, and more.

The MSO and the PC are connected by a Management Services Agreement (MSA) that defines each party's roles, responsibilities, and boundaries. Done correctly, this lets the business raise capital and scale while the licensed physician retains genuine authority over clinical care.

Why Startups Use the MSO-PC Model

• CPOM compliance. In many states, corporations may not practice medicine or employ physicians to deliver care. The MSO-PC model lets a company operate compliantly while keeping the business viable.
• Operational flexibility. The MSO runs day-to-day operations so the PC can focus on care delivery and clinical oversight.
• Investor participation. Investors can participate in the business entity (the MSO) without violating laws that restrict non-physician ownership of the clinical entity.
• Scalable expansion. A single MSO can support multiple PCs — or one "hub" PC that registers to do business across states — each structured to its local rules. That makes the model well-suited to nationwide digital health growth.

What Changed in 2025–2026 — and Why Structure Quality Now Matters More

For years, the MSO-PC model (sometimes called the "friendly PC" model) was treated almost as a formality. That era is ending. A wave of state action in 2025–2026 has put the structure — and especially how much control the MSO actually exerts — under real scrutiny:

• California. SB 351 and AB 1415 both took effect January 1, 2026. SB 351 codifies CPOM separation and bars private equity firms and hedge funds from controlling the clinical decisions of physicians and dentists. California's Attorney General has already examined friendly-PC arrangements and reached an enforcement settlement with a management company — a signal that regulators are looking past the paperwork to the substance of control.
• Oregon. SB 951 is the strictest CPOM law in the country to date. Most physician, physician-associate, and nurse-practitioner noncompetes became void as of June 9, 2025, and the law's restrictions on MSO control phase in on a staggered timeline — January 1, 2026 for MSOs and practices formed after June 9, 2025, and January 1, 2029 for those that already existed. Notably, the law is self-executing, with no state agency issuing waivers — which means compliance is on you and your counsel.
• A broader trend. Other states have introduced similar measures with mixed results (Washington's sweeping CPOM bill stalled in 2026, for example), but the direction is unmistakable: more transparency, tighter limits on corporate control, and a harder look at the friendly-PC model.

The takeaway: a structure that merely looks compliant on paper is no longer enough. The newest laws reward structures where the physician owner exercises genuine, independent control — and penalize arrangements where the MSO effectively runs the practice.

Best Practices for MSO-PC Structuring

• Have experienced CPOM counsel draft your documents. The PC formation, corporate documents, and the MSA are legal instruments. They should be drafted and executed by qualified counsel, and reviewed on the PC owner's behalf by their own attorney — standard practice in any sound arrangement.
• Preserve genuine PC independence. The physician owner should hold real authority over clinical matters. Avoid MSA provisions that hand the MSO control the newest laws restrict — for example, authority over clinical decisions, or restrictive covenants now void in states like Oregon.
• Keep clean financial separation between clinical revenue and MSO management fees, with fees set at fair market value.
• Design for the strictest state you'll touch. If you plan to operate in California or Oregon, build to their standard rather than retrofitting later.
• Review the structure on a schedule. State law is moving quickly. A structure that was compliant at launch can drift out of step as new laws take effect.

How MedPath Helps
