For most licensed clinicians the choice is made by state law before it is made by preference: where a professional entity is required, you form a PLLC if your state offers one for your license and a PC (or professional association) if it does not, and a plain LLC is usually reserved for the non-clinical management company. A PLLC and a PC give the same basic liability protection; they differ in who may own them, how much corporate formality they carry and how they are taxed by default. Every rule below varies by state — confirm with a healthcare attorney before you file.
PC vs PLLC vs LLC for a medical practice: side by side
All three are creatures of state law, and all three keep business debts and other people’s mistakes away from your personal assets. Names vary: some states call the professional corporation a professional association (PA) or a professional service corporation (PSC).
| Factor | LLC | PLLC | PC (or PA / PSC) |
|---|---|---|---|
| Who can own it | Anyone, including non-clinicians and other companies | Licensed professionals only, usually in the same or a legally permitted related profession | Licensed professionals only, as shareholders |
| Can it deliver clinical care? | Only in states that do not require a professional entity | Yes, where the state offers a PLLC for your license type | Yes; the only option for physicians in some states |
| Default federal tax | Disregarded entity (one owner) or partnership | Same as an LLC | C corporation unless an S election is filed |
| S-corp election | Available | Available | Available |
| Governance | Operating agreement, annual report | Operating agreement, annual report, sometimes licensing-board sign-off on the filing | Bylaws, shareholders, directors, officers, minutes, annual report |
| Typical role in a telehealth hormone clinic | Management company (MSO), brand, marketing | Solo or small-group clinical entity | Clinical entity in PC-only states; the friendly PC in an MSO structure |
Two state-level facts usually settle the question. First, not every state offers a PLLC for every license: California, for example, does not let LLCs render licensed medical services, so physicians there practice through a professional medical corporation. Second, some states never require a professional entity at all and let clinicians use an ordinary LLC. Read your secretary of state’s filing options and your licensing board’s rules together; that tells you which column is actually open to you.
What the entity protects — and what it never does
No LLC, PLLC or PC shields a clinician from liability for that clinician’s own professional negligence. Malpractice insurance does that job. What the entity does is separate your personal assets from:
- Business debts and contracts: software agreements, leases, vendor and marketing disputes.
- Employment and contractor claims.
- In many states, the negligence of other clinicians and staff in the practice, as long as you were not the one supervising or directing the care in question.
The shield only holds if you maintain it: a separate bank account, no commingling of personal and practice money, contracts signed in the entity’s name, annual reports filed on time and adequate insurance in force.
The corporate practice of medicine doctrine drives the structure
The corporate practice of medicine (CPOM) doctrine is the rule — found in statute, board regulation or case law depending on the state — that only licensed physicians, or entities owned by them, may practice medicine or employ physicians to do so. The policy is simple: a business owner without a license should not control clinical judgment. California, Texas and New York are commonly cited as strict CPOM states; other states enforce the doctrine lightly or carve out broad exceptions.
For a telehealth hormone clinic, CPOM answers three practical questions:
- Who may own the entity that holds the patient relationship, engages the prescribers and collects fees for clinical services.
- Whether a non-physician — an NP, PA, RN, chiropractor or business partner — may own any part of that entity.
- Whether you need two entities instead of one.
Because telehealth care is generally treated as delivered where the patient is located, the CPOM rules of every state where you see patients matter, not only your home state. Entity structure is one piece of a wider telemedicine hormone clinic compliance picture that also includes licensure, prescribing rules and advertising.
MSO and friendly-PC structures
When the person building the clinic cannot legally own the clinical entity, or wants non-clinician partners or investors, the standard answer is a two-entity structure:
- The professional entity (PC or PLLC), owned by a physician or other permitted licensee — often called the friendly PC. It engages the clinicians, owns the patient records, sets clinical protocols and collects patient fees.
- The management services organization (MSO), usually an ordinary LLC that anyone may own. It supplies the non-clinical side: brand, website, marketing, software, support staff, billing and bookkeeping.
- The management services agreement (MSA) between them, under which the professional entity pays the MSO a management fee.
Guardrails that matter:
- Clinical decisions — who is treated, with what, at what dose, by which clinician — stay with the professional entity and its licensed owner.
- The management fee should reflect fair market value for services actually provided. Some states treat a percentage-of-revenue fee as prohibited fee-splitting, so a flat or cost-plus fee is often the safer drafting choice.
- Succession and stock-transfer agreements, which let the MSO help name a replacement owner, must not hand the MSO practical control of the practice.
- Scrutiny is rising. Oregon and California, among others, passed laws in 2025 limiting how much control management companies and investors may exert over medical practices. Have counsel check the current rule in each state you serve.
NP and PA ownership rules by state type
Whether a nurse practitioner or physician assistant can own the clinical entity depends on two separate things: scope-of-practice law and entity-ownership law. They do not always line up.
- Full-practice-authority states. An NP can generally evaluate, diagnose and prescribe without a physician agreement and can usually own a professional entity under a nursing license. Check whether that entity may also engage a physician, and what changes if it does.
- Reduced- or restricted-practice states. An NP may often still own the business, but must have a collaborating or supervising physician agreement in place to practice. In some of these states the physician’s role must be real and documented — chart review, availability, protocol sign-off — not a signature on file.
- Strict CPOM states with physician-ownership rules. Non-physician owners may be capped at a minority share or barred from the medical entity entirely. NPs and PAs commonly build here through an MSO paired with a physician-owned PC.
- PAs in any state. PA practice is tied to physician collaboration or supervision in most states. Some states allow PA ownership or co-ownership of a practice; others cap or prohibit it.
Treat these as categories, not answers. A state can be full-practice for nursing and still restrict who owns an entity delivering what its medical board considers medicine.
Multi-state telehealth: foreign registration
An entity formed in your home state is a foreign entity everywhere else. Once you treat patients in another state on a regular basis, that state may consider the entity to be doing business there and require it to register (foreign qualification). For professional entities this is not a formality:
- Some states will only qualify a foreign PC or PLLC if every owner — or at least the owners practicing there — holds that state’s license.
- Some strict states effectively require a separate in-state professional entity instead.
- Each registration brings a registered agent (commonly $100 to $300 a year, as an estimate), a filing fee, an annual report and sometimes a franchise or minimum tax — California’s $800 minimum franchise tax is the best-known example.
Decision rule: do not register in 20 states on day one. Launch in the one to three states where you are licensed and have demand, then add states in batches, with the entity question answered for each state before the first patient is seen there.
S-corp tax election: when it pays
S corporation is a tax status, not an entity type. An eligible LLC, PLLC or PC can elect it with the IRS. Without the election, a single-owner LLC or PLLC is taxed like a sole proprietorship, with self-employment tax on all net profit, and a PC is taxed as a C corporation.
With the election, the owner-clinician must be paid a reasonable salary through payroll; profit above that salary is distributed without the 15.3 percent self-employment tax. A worked illustration: a solo PLLC nets $200,000. Paying a $110,000 salary and distributing the remaining $90,000 can reduce payroll-type taxes by very roughly $10,000 a year, before the added costs of a payroll service and a separate corporate return (often $1,500 to $3,000 a year, as an estimate). Many CPAs use a rule of thumb that the election starts to make sense somewhere around $80,000 to $100,000 of net profit; below that, the compliance cost can eat the savings. State treatment of S corporations differs, and an unreasonably low salary invites IRS attention. This is an illustration, not tax advice — run your own numbers with a CPA who works with medical practices.
A decision sequence for a telehealth hormone clinic
- List your license type and every state where you will see patients in the first 12 months.
- For each state, determine whether a professional entity is required and which forms (PLLC, PC, PA) are available to your license.
- Check CPOM and ownership rules: may you own the clinical entity outright? If not, plan a friendly PC plus an MSO.
- If you have a free choice between PLLC and PC, most solo and small-group owners take the PLLC for lighter formalities and flexible tax treatment.
- Form the home-state entity, obtain an EIN, open the bank account and put malpractice coverage in the entity’s name.
- Decide on the S election with a CPA once profit is predictable.
- Foreign-qualify or form additional entities as each new state is added.
Entity formation is an early step in the wider sequence of starting a telemedicine hormone clinic. Licensing, DEA registration, pharmacy and lab accounts all key off the legal name and EIN, so mistakes here are expensive to unwind.
Common entity mistakes
- Forming a standard LLC online in a state that requires a professional entity for your license.
- Assuming the entity protects against your own malpractice, and under-insuring as a result.
- A non-physician owning the clinical entity outright in a strict CPOM state.
- A friendly PC whose physician owner has no real involvement while the MSO makes clinical calls.
- Seeing patients in new states without checking foreign registration and ownership rules.
- Electing S-corp status too early, or paying no salary at all.
FAQ
Is a PLLC or a PC better for a medical practice?
Where both are available, many solo and small-group practices choose a PLLC because it has fewer corporate formalities and flexible default taxation, and it can still elect S-corp status. A PC makes sense where the state requires it or where owners want a traditional corporate structure with shareholders and a board. Liability protection is essentially the same; confirm what your state allows.
Can a nurse practitioner own a telemedicine hormone clinic?
In many full-practice-authority states, yes, typically through a professional entity under the nursing license. In reduced- or restricted-practice states and strict CPOM states, an NP may need a collaborating physician, a physician-owned professional entity paired with an NP-owned MSO, or both. This varies by state — confirm with your board of nursing and a healthcare attorney.
Do I need a separate entity in every state where I see telehealth patients?
Not always. Many states let you register your existing professional entity as a foreign entity, sometimes on the condition that its owners hold that state’s license. A few effectively require a separate in-state professional entity. Answer the question state by state before you take patients there.
