The MSO and the friendly PC, in plain English

Look under any compliant telehealth brand in the United States and there are at least two companies: a management services organization, and a professional corporation owned by a licensed physician. Founders usually meet the MSO and friendly PC structure for the first time in a term sheet or a diligence checklist, described in a sentence and then waved past. It deserves a plain explanation, because the founder will live inside it for the life of the business, and the details decide whether the founder owns a clinic or rents one.

This post explains what each entity does, what makes the physician's practice "friendly," how money moves between the two, and what to check before relying on a structure someone else drafted. The state-by-state side of the underlying rule is covered in the post on corporate practice of medicine rules for telehealth; this one stays on the structure itself.

Why the two-company rule exists

Many states enforce some version of the corporate practice of medicine doctrine, a rule that a business corporation may not practice medicine or employ physicians to practice it on the corporation's behalf. The reasoning is old and simple. If a company owns the doctor, the company's interest in revenue can leak into the doctor's decisions about tests, prescriptions and follow-up. So the practice of medicine is reserved to entities owned by licensed clinicians, and anyone else who wants to be in the business contracts with such an entity rather than owning it.

Because the doctrine is state law, it varies. Some states enforce it through statute, some through board opinions and attorney-general letters, and some barely enforce it at all. The strict states include some of the largest patient markets, and an online clinic reaches all of them at once. The practical result is that a national telehealth brand builds the structure to satisfy the strictest state it operates in, which means building it properly everywhere rather than arguing about which states could be skipped.

What the friendly PC does

The professional corporation, in some states a professional limited liability company, is the clinical company. A licensed physician owns it. It employs or contracts the physicians and nurse practitioners, holds the clinical policies and protocols, decides who gets hired on the clinical side, and owns the medical records. Every prescription is written under its authority, every patient relationship is legally with it, and every clinical complaint is answered by it. The glossary entry on the friendly PC has the short definition.

The physician owner is not a figurehead on a good structure. The owner is typically the medical director, or supervises the physician who is, signs off on protocols, and answers to the state board if something goes wrong. A structure in which the physician owner has never read the protocols is a structure with a problem waiting for a board inquiry.

What the management services organization does

The management services organization, or MSO, is everything that is not the practice of medicine. It owns the brand, the trademarks, the website and software, the marketing, the customer support team and the working capital. It leases space or equipment where there is any, employs the non-clinical staff, runs billing and collections, negotiates with vendors, and provides all of this to the PC under a management services agreement in exchange for a fee.

Founders and investors own the MSO. It is where the equity lives and where enterprise value accrues, because the brand, the technology and the commercial relationships sit in it. A buyer acquiring a telehealth company buys the MSO and steps into its agreement with the PC. That is also why the agreement's terms on termination and succession matter as much as its terms on fees.

What makes the PC friendly

"Friendly" describes the relationship between the two companies, not a personality. The physician who owns the PC is aligned with the MSO by a set of agreements that keep the two together. The most important is usually a stock transfer restriction or succession agreement, which says what happens to the physician's shares if the physician dies, retires, loses a license, or wants out: the shares pass to another licensed physician designated under the agreement rather than to the physician's estate or a stranger. Without it, the clinical company could walk away with the practice, or a probate court could end up holding a medical practice.

The physician keeps genuine clinical authority; the MSO keeps continuity. Stricter states look hard at whether the physician's authority is real. If the succession agreement lets the MSO remove the physician owner at will and for any reason, some regulators read that as the MSO owning the practice in substance, which is the thing the doctrine forbids. Well-drafted agreements set out defined triggers and a process for choosing the successor physician, so continuity does not depend on control.

How the money moves

Patients pay the clinical company for medical services. The PC pays the MSO a management fee for the services the MSO provides. The fee has to be defensible as fair market value for those services, and how it is set is one of the most scrutinized terms in the structure. A flat monthly fee, or a fee built up from the cost of the services plus a reasonable margin, is the conservative design. A fee set as a percentage of the practice's revenue is common but draws attention in states with fee-splitting rules, because it can look like the MSO sharing in professional fees rather than being paid for management.

Regulators do examine these arrangements. In one example, the HHS Office of Inspector General's Advisory Opinion 25-03, summarized by the law firm McGuireWoods, approved a telehealth arrangement involving several MSOs because the payments fit within a federal anti-kickback safe harbor. Most cash-pay telehealth brands sit outside the federal programs that statute covers, but the opinion shows what a careful design looks like: fees for real services, at fair market value, not tied to referrals or prescription volume.

Cash flow follows the same lines. Because patients pay the PC, the PC's bank account is where revenue lands first, and the management agreement governs how and when it moves to the MSO. Founders sometimes find that a structure drafted by a platform routes patient payments through the platform's own merchant account rather than the brand's, which is convenient until the founder wants to leave.

The doctrine draws one line: clinical judgment belongs to clinicians. A well-drafted structure makes that line explicit, boring and easy to point to in an audit.

What founders should check

A platform or a law firm handing over this structure will call it standard. Standard structures still differ in the terms that matter. Before relying on one, verify the following:

• Which licensed physician owns the PC, and what the succession agreement says if that physician leaves. This is the most common point of failure in the structure.
• How the management fee is set: flat and documented as fair market value, or a percentage of revenue, which draws scrutiny in stricter states.
• Who owns the patient records and the data as a matter of contract, and what happens to both if the founder terminates the management agreement. The guide on who owns the patients covers this in detail.
• Whether the management agreement reserves clinical decisions, meaning protocols, clinician hiring and prescribing, to the PC on paper, and whether daily operations match.
• Whether the structure already exists, who drafted it, whether licensed clinicians run it, and whether the brand's patients, records and data leave with the brand. A platform's own PC serving several brands is a normal arrangement; a contract that keeps the patients with it is not.
• Whether the physician owner is licensed in the states the brand operates in, or whether the structure needs a separate PC in states that require in-state ownership.

That last point trips up more national brands than any other. A few states require the professional entity to be owned by a physician licensed in that state, so a single PC does not cover the map. The usual answer is a small set of PCs, each owned by a properly licensed physician and each with its own management agreement with the same MSO, which is one reason experienced counsel costs what it does.

Substance beats paperwork

One warning that health-care counsel will give unprompted: regulators read substance, not letterhead. If the MSO's executives are directing prescribing patterns in a group chat, adjusting protocols to move a product, or deciding which clinicians to hire, the cleanest documents will not help. The structure works when the operating reality matches it. Clinicians decide clinical questions, the business runs everything else, and the management fee is earned by services actually rendered.

None of this is an argument against the structure, which is the only one that works across strict states and is well understood by boards, buyers and lenders. The point is that the structure is a set of operating habits as well as a set of documents, and the habits have to be trained into a team that is used to running a consumer business.

Every brand Tessic Health stands up runs on one MSO and friendly-PC structure that already exists: a medical practice owned and run by licensed clinicians that serves every brand on the platform, with the client's company running the business of its own brand and the agreement written so the client's patients, records and data leave with it at any time. However a founder builds, the same terms are worth insisting on. They are the difference between owning a telehealth company and renting one.

Questions operators ask

Does a nurse-practitioner-led clinic need the same structure? In states that grant nurse practitioners full practice authority, a nurse practitioner may be able to own the professional entity, and some states have looser rules for non-physician clinicians. In states that restrict ownership to physicians, the structure is the same. Counsel should map ownership rules state by state, and the state pages on this site list where to start.

Can the founder be the physician owner? If the founder is a licensed physician, yes, and it simplifies alignment. It also concentrates risk: the founder's license, the clinical liability and the equity are all in one person, and the succession agreement still has to be drafted for the day the founder leaves.

What does the physician owner get paid? Typically a fixed fee or salary for the medical director role, documented as fair market value, separate from any profit of the PC. Some structures also pay a nominal amount for the ownership itself. What the physician cannot be paid for is referrals, prescriptions or volume.

Can a management services organization for telehealth be based in one state and serve patients everywhere? The MSO can be anywhere. The professional entity and the clinicians have to satisfy each state where patients are located, which is why the PC side of the structure is the one that multiplies.
