Usually yes, once you operate in more than one corporate-practice state, and the reason is not the corporate practice doctrine itself. It is the ownership tests each state writes into its professional corporation statute. Several require every shareholder to be licensed in that state, some require the state’s own board to certify it, and one renews the entity’s right to exist every two years. A single professional corporation cannot satisfy those tests in two states at once unless every owner holds every license.
The sequence
Work through the states you operate in, in this order. Stop at the first “no.”
- Does the state enforce the corporate practice of medicine? If not, a non-physician entity may own the clinic and the PC question falls away for that state (subject to step 4). Arizona, New Hampshire and Ohio sit here. If yes, go to step 2.
- Who may own the professional entity, and licensed where? This is where multi-state structures break. See the table.
- Does the entity itself need a certificate or registration? West Virginia and Alaska say yes. That is a filing per state, not per company.
- What else requires an in-state presence? Telehealth registration, facility licensure, registries, and pharmacy or lab accounts that require an in-state prescriber.
- Can the same physicians own every entity? If your physician-owner is licensed in three states, three PCs with one owner is straightforward. If each state needs a different licensed owner, you are building several friendly PCs and the MSO is the only thing they share.
Step 2: the ownership tests, in the statutes’ own terms
| State | Who may own | The detail that breaks a single-entity plan | Authority |
|---|---|---|---|
| California | Licensed physicians, under Moscone-Knox | Strictest enforcement; the medical entity must be physician-owned and the management company separately owned | B&P 2052, 2400; Corp. Code 13400 et seq. |
| Wyoming | Persons licensed to practice the profession by the state of Wyoming | The statute says licensed by Wyoming, not licensed anywhere | W.S. 17-3-101 |
| Michigan | All shareholders licensed or legally authorized in Michigan to render the service | In-state authorization for every shareholder | MCL 450.224 |
| Wisconsin | Licensed individuals only; a non-licensee may not have any part in ownership or control | Converts automatically to a business corporation if all shareholders cease to be licensed | Wis. Stat. 180.1901, 180.1921 |
| Nevada | Natural persons licensed in the same services | No transfer except to an eligible person; failure to require compliance is a ground for forfeiture of the charter | NRS 89.070 |
| Delaware | Persons licensed to render the same professional service | Automatic conversion if all shareholders cease to be licensed | Del. Code tit. 8 ch. 6 |
| District of Columbia | Shareholders, directors and officers each licensed for the service | One exception: the secretary of a sole-shareholder corporation | D.C. Code 29-508(b) |
| New Jersey | Licensed professionals | Allstate v. Northfield: designing and selling a structure with a figurehead physician owner was itself actionable under the Insurance Fraud Prevention Act | N.J. Sup. Ct. 076069 (2017) |
Read Wyoming and Michigan together and the single-PC plan is over: a physician licensed only in Texas cannot be a shareholder of the Wyoming entity, and a Wyoming PC cannot lawfully own the Michigan clinic. Each state’s clinic needs an entity whose owners pass that state’s test.
Step 3: states that license the entity, not just the people
West Virginia: it is unlawful for a corporation to practice medicine without a certificate of authorization from the Board, issued on proof that each shareholder is a licensed physician or podiatrist. The certificate runs two years and the corporation must register biennially or it expires automatically (W. Va. Code 30-3-15). The certificate is a per-entity, per-state obligation that lapses silently.
Alaska: a certificate from the profession’s regulatory board certifying that each incorporator, director and shareholder is licensed must be filed with the articles of incorporation (AS 10.45). The board checks the owners before the entity exists.
Neither can be satisfied by a foreign entity’s home-state paperwork.
Step 4: presence requirements that survive even in permissive states
- Telehealth registration. Florida lets an out-of-state provider register to deliver telehealth to Florida patients, but a registered provider may not open a physical office or provide in-person services in Florida (Fla. Stat. 456.47(4)). The moment you lease a room, you need a Florida structure.
- Facility statutes and registries. Florida’s clinic licensure, Tennessee’s and Indiana’s registries, Connecticut’s named-provider requirement and Rhode Island’s Medical Spas Safety Act attach to a location in the state.
- Collaboration rules with in-state hours. Mississippi requires the collaborating physician to practice in-state 20 hours a week, telemedicine excluded. A physician-owner in another state cannot supply that.
- Pharmacy and lab accounts. Many require a prescriber of record licensed in the patient’s state.
Step 5: what the multi-state structure actually looks like
One management company. One clinical entity per corporate-practice state, owned by a physician who passes that state’s ownership test. The same physician can own several where their licenses allow. Where they do not, a different licensed physician owns that state’s PC, and the management agreement, the stock transfer restriction agreement and the fixed management fee are what keep the model consistent across entities. The friendly PC and MSO structure is the template; the multi-state version repeats the PC half as many times as the states require. A national network of credentialed providers is what makes each state’s PC operable without recruiting from scratch.
New Jersey’s warning applies to every copy: the physician owner must actually own and actually direct. A figurehead who holds shares under an agreement never to exercise them is the Allstate v. Northfield fact pattern, and the New Jersey Supreme Court held that promoting and assisting the creation of that structure was itself a violation.
What this means for you
List the states where you have or plan a physical location. For each, answer the five questions in order and write the answer down with the statute next to it. Expect to end up with one PC per corporate-practice state, each owned by a physician licensed there, and one MSO that contracts with all of them on the same fixed-fee terms. Calendar West Virginia’s biennial registration and any state whose certificate lapses automatically. Keep telehealth-only states on telehealth registration and do not lease space there until the entity exists. And do not let anyone sell you a structure where the physician owner is a name on a certificate, because a court has already said what that is. See California’s version of the rules, Wyoming’s licensed-by-Wyoming test and the New Jersey case.

Frequently asked questions
Can one professional corporation operate in multiple states?
Rarely, once more than one corporate-practice state is involved. Wyoming requires shareholders licensed by Wyoming, Michigan requires every shareholder authorized in Michigan, and West Virginia and Alaska require the entity itself to be certified by the state board. A single PC cannot pass those tests in two states unless every owner holds every license, so the usual structure is one PC per state.
Do you need a separate MSO in every state?
No. The management company is not practicing medicine and is not subject to the professional corporation ownership tests. One MSO can contract with each state’s PC on the same terms. What must repeat is the clinical entity, and only in states that enforce the corporate practice of medicine.
Which states do not require a physician-owned entity?
Arizona, New Hampshire and Ohio are permissive on ownership, though each still requires licensed people to perform the medical acts and a physician or qualifying NP to direct them. Even in those states, facility statutes, telehealth registration rules and pharmacy requirements can require in-state presence.
What is a foreign professional corporation and can it register in another state?
A PC formed in one state may register to do business in another, but registration does not satisfy the second state’s ownership test. Michigan, Wyoming, Nevada and Delaware look at who the shareholders are and where they are licensed; West Virginia and Alaska require their own board’s certification. A foreign registration is a filing, not a license to practice.
Can a physician licensed in several states own the PC in each?
Yes, and that is the cleanest multi-state structure: one physician-owner with licenses in each state owns each state’s PC. Where the physician lacks a license, a different physician licensed there must own that PC, and the management agreement and stock transfer restriction agreement keep the model consistent across entities.
