The decision in one table
Four questions that decide it
1. Will a non-licensee own equity or exercise control?
This is the threshold question. In CPOM states, ownership of the professional entity is restricted to licensees of the same profession, and in the strictest states control matters as much as ownership. If the answer is yes, a non-clinician founder, an investor, a holding company, then the equity has to sit somewhere other than the professional entity, and that somewhere is the MSO. If the answer is no, and it will stay no, the structure may be unnecessary overhead.2. What does your state say, for your profession?
CPOM is not one rule. It is fifty-one separate bodies of law, and within each state it varies by profession. Roughly 32 states plus the District of Columbia recognize or enforce a CPOM doctrine in some form; the rest do not, though several of those still restrict professional-entity ownership to licensees through their professional corporation acts.1 Some patterns worth knowing before you look up your state:- A state can have no CPOM doctrine and still restrict who owns a PC. Delaware and Alaska, for example, have no meaningful CPOM doctrine but still limit professional corporation ownership to licensed persons.
- A state can have a workaround. Florida’s Health Care Clinic Act (Fla. Stat. ch. 400, pt. X) allows a non-physician-owned entity to bill for care if it holds a health care clinic license, which is a materially different structure from a friendly PC.2
- A state can be strict for one profession and loose for another. Mississippi is permissive for medicine and strict for optometry. Dentistry is frequently regulated more explicitly than medicine.
- The rules are moving. Oregon (SB 951, 2025), California (SB 351, effective January 1, 2026), and Vermont (Act 133, 2026) all tightened materially in the last two years. See the legislation tracker.
3. Do you intend to operate in more than one state?
Professional entities are state-chartered and generally cannot foreign-qualify to practice in another state. A five-state group is five PCs, each with an in-state-licensed owner, five sets of payer enrollments, and five sets of books. An MSO is the only thing in that picture that can be a single national entity. Once you have more than one PC, you effectively have an MSO whether or not you call it one, because something has to hold the brand, the technology, the contracts, and the non-clinical staff across all of them. See Why multi-state groups have one PC per state.4. Will you raise capital or sell?
Investors underwrite the MSO, because the MSO is the only side they can own. Every diligence process on an MSO-PC group reconstructs the same things: is the MSA enforceable in each state, was the management fee actually paid in cash, are the intercompany loans papered, and would the structure survive a CPOM challenge. Groups that improvise the structure early and clean it up before a raise pay for that in valuation and in legal fees. If a raise or a sale is plausible within three years, build the structure correctly at formation. See How investors read MSO-PC financials.The honest counter-cases
The MSO-PC structure is not free, and it is over-applied. Cases where you should push back on advice to build one: You are a solo or small-group clinician-owner in your own state. If you are the licensee, you own the practice, and no outside money is coming, a single professional entity is simpler, cheaper, and equally compliant. Adding an MSO you also own creates two tax filings, an intercompany fee that has to be FMV-supported, and no benefit you couldn’t get from a bookkeeper. You are testing an idea. Formation, an MSA drafted by healthcare counsel, and a stock transfer restriction agreement will run into the tens of thousands of dollars before you see a patient. If you are validating demand, validate it first, as a cash-pay service, as a contractor to an existing practice, or in a state that permits a simpler shape. Your business does not deliver care. Selling software, staffing, or RCM services to practices does not implicate CPOM. Plenty of companies build a “friendly PC” reflexively when they have no clinical delivery at all. A licensed founder can hold it alone, for now. Some groups start with a clinician-founder-owned PC and add the MSO when the first outside dollar arrives. That is a legitimate sequencing choice, but re-papering later means moving assets, contracts, and payer enrollments between entities, which is more painful than it sounds. See Alternatives to MSO-PC for the full set of other shapes: hospital employment, clinical franchising, licensing-only models, and the clinic-license route in states that offer it.If the answer is yes
