A nurse practitioner can open their own practice in most states, but not in all of them. Thirty states, Washington, D.C., and two U.S. territories grant full practice authority, letting an NP diagnose, treat, prescribe, and own a clinic without a physician relationship. Everywhere else, opening a practice starts with securing a collaborating physician. Even in full practice states, certain clinic types, including medspas, hormone therapy clinics, and IV hydration businesses, still trigger a physician oversight requirement under state medical practice law.
Key takeaways
- Whether you can open a practice depends on your state’s practice authority tier. Full practice states allow independent ownership; restricted states require a collaborating physician before an NP can practice at all. (Jump to Section)
- More than half of U.S. states now grant full practice authority. But even there, clinic types like medspas and IV hydration businesses can still require physician oversight. (Jump to Section)
- NPs in restricted and reduced practice states need a collaborating physician agreement in place before opening. Medical Director Co. places a vetted physician in twenty-four hours. (Jump to Section)
- Practice authority determines whether you can open a practice. Your service menu determines whether you need a physician on record, no matter what your state allows. (Jump to Section)

The Three Practice Authority Tiers Explained
Every state classifies nurse practitioners into one of three practice authority tiers, and the American Association of Nurse Practitioners (AANP) tracks all three nationally. The tier determines whether an NP needs a physician relationship to diagnose, prescribe, or open a clinic. Here is what each tier actually permits.
- Full practice authority: An NP can evaluate patients, diagnose conditions, order and interpret tests, and prescribe medications, including controlled substances, entirely under the state board of nursing’s licensure, with no physician sign-off required.
- Reduced practice authority: An NP can run day-to-day clinical operations but needs a documented collaborative agreement with a physician for at least one function, most often prescribing controlled substances.
- Restricted practice authority: State law requires ongoing physician supervision or delegation across most or all clinical decisions, so an NP cannot legally open an independent practice without a supervising physician in place from day one.
The tier your state assigns is set by the board of nursing, but it only answers part of the ownership question. A physician relationship required at the nursing-board level is separate from any physician oversight your specific clinic type might trigger under state medical practice law, which the sections below cover in detail.
Full Practice Authority States: Where NPs Can Practice Independently
Thirty states, Washington, D.C., and two U.S. territories currently grant full practice authority. NPs in these jurisdictions can open a clinic and run it without a collaborating physician for standard clinical services. Several still impose a one-time transition period, a supervised-hours requirement, or a mentorship before full independence takes effect.
State/Territory | Full Practice Since | Key Notes |
|---|---|---|
Alaska | Long-standing FPA | No transition-to-practice period required |
Arizona | Long-standing FPA | Practice limited to NP’s certified specialty |
Colorado | FPA after 750 supervised hours | Attestation of hours required; NPs cannot sign DNR orders |
Connecticut | FPA after transition-to-practice period | Requires collaborative period before independence |
Delaware | FPA after 4,000 hours and 2 years | APRN transition period applies |
Guam | Territory-level FPA | Follows AANP full practice classification |
Hawaii | Long-standing FPA | Recognized as primary care providers |
Idaho | Long-standing FPA | Recognized as primary care providers |
Iowa | Long-standing FPA | No transition period |
Kansas | FPA since 2022 | Transition-to-practice period applies to new NPs |
Maine | Long-standing FPA | No transition period |
Maryland | FPA after 18-month mentorship | Mentorship with a physician or certified NP required |
Massachusetts | FPA since 2021 | Fifteen hours of continuing education every two years |
Minnesota | Long-standing FPA | No transition period |
Montana | Long-standing FPA | No transition period |
Nebraska | Long-standing FPA | No transition period |
Nevada | Long-standing FPA | No transition period |
New Hampshire | Long-standing FPA | No transition period |
New Mexico | Long-standing FPA | State offers rural practice tax incentives |
New York | FPA tied to experience threshold | Status under legislative review in 2026; confirm current rules |
North Dakota | Long-standing FPA | No transition period |
Northern Mariana Islands | Territory-level FPA | Follows AANP full practice classification |
Oregon | Long-standing FPA | No transition period |
Rhode Island | Long-standing FPA | No transition period |
South Dakota | Long-standing FPA | No official primary care designation in state law |
Utah | Long-standing FPA | No transition period |
Vermont | Long-standing FPA | No transition period |
Washington | Long-standing FPA | No transition period |
Washington, D.C. | Long-standing FPA | No transition period |
Wyoming | Long-standing FPA | No transition period |
Last updated: July 2026. State legislatures amend scope-of-practice law regularly. Confirm current status with your state board of nursing or the AANP State Practice Environment map before making a business decision.
Once you finish your transition period, it is done for good. You will not repeat it if you move within the state or add new services later. But full practice authority only covers your license, not your clinic. Open a medspa, hormone therapy clinic, or IV hydration business in any of these states, and you may still need a physician on record under that state’s medical practice law.
Reduced Practice Authority States: What Is Still Required
Fifteen states and territories fall into reduced practice authority. An NP here can run most of the clinical practice alone, but state law requires a signed collaborative agreement with a physician for at least one function, almost always prescribing. That agreement is a legal requirement, so it’s not a formality you can skip if you find the right supervising arrangement.
State/Territory | What Requires Physician Collaboration | Notes |
|---|---|---|
Alabama | Prescribing, including controlled substances | Collaborative agreement filed with the state |
American Samoa | Prescribing authority | Territory-level classification |
Arkansas | Controlled substance prescribing | Agreement scope defined by state statute |
Illinois | Controlled substance prescribing | Written collaborative agreement required |
Indiana | Controlled substance prescribing | Agreement must specify prescribing protocols |
Kentucky | Controlled substance prescribing | CAPA-CS agreement required for Schedule II-V |
Louisiana | Prescribing and select clinical decisions | Collaborative practice agreement on file |
Mississippi | Controlled substance prescribing | Agreement required with a Mississippi-licensed physician |
New Jersey | Controlled substance prescribing | Joint protocol required |
Ohio | Prescribing, including controlled substances | Standard Care Arrangement required |
Pennsylvania | Prescribing, including controlled substances | Collaborative agreement required |
Puerto Rico | Prescribing authority | Territory-level classification |
U.S. Virgin Islands | Prescribing authority | Territory-level classification |
West Virginia | Controlled substance prescribing | Collaborative agreement required |
Wisconsin | Controlled substance prescribing | Written collaborative agreement required |
The agreement itself is not one-size-fits-all. In some states, like Illinois or Wisconsin, it only has to cover prescribing. In others, like Missouri-style chart review states, it can extend to site visits, referral protocols, or specific procedures your clinic performs. Before you open, ask your collaborating physician’s agreement to spell out exactly what it covers, because “collaborative agreement” means something different in Ohio than it does in Kentucky.
Restricted Practice Authority States: Where a Collaborating Physician Is Required Before You Can Open
Eleven states classify NP practice as restricted, requiring ongoing physician supervision or delegation across most clinical decisions. An NP here cannot legally open an independent practice without a physician relationship established first. That physician has to sign off before the clinic opens, not after.
State | Oversight Required | What a Collaborative Agreement Must Cover | Notes |
|---|---|---|---|
California | Supervision or standardized procedures | Scope of practice, prescribing protocols, review intervals | Recent reforms allow limited autonomy after experience thresholds |
Florida | Supervision for autonomous practice designation | Protocol agreement and chart review terms | Autonomous practice option exists with added certification |
Georgia | Supervision agreement | Prescribing scope and delegation terms | Nurse Protocol Agreement required |
Michigan | Supervision or collaborative agreement | Prescribing and treatment protocols | Agreement filed with the state |
Missouri | Collaborative practice agreement | Site visit and chart review requirements | Distance and frequency requirements apply |
North Carolina | Collaborative practice agreement | Prescribing authority and quality assurance review | Recently updated supervision ratios |
Oklahoma | Supervision agreement | Prescribing scope and delegation | State medical board involvement required |
South Carolina | Collaborative practice agreement | Prescribing scope and review terms | Agreement renewal required periodically |
Tennessee | Collaborative practice agreement | Prescribing scope, chart review, and site visits | Site visit frequency defined by statute |
Texas | Prescriptive authority agreement | Prescribing protocols and quality assurance | Agreement required for controlled substance prescribing |
Virginia | Practice agreement during transition period | Prescribing scope and supervision terms | Full autonomy available after experience threshold |
Most of these states also set a minimum site-visit or chart-review frequency, so the agreement is not a one-time signature. Missouri and Tennessee, for example, require your collaborating physician to conduct periodic reviews on a schedule set by statute, and skipping them can put your license at risk during an audit. Some states, like California, Florida, and Virginia, also offer a path to more autonomy once you clear a set number of practice hours, so restricted today does not always mean restricted for your entire career.
If You Are in a Restricted Practice State: Your Immediate Next Step
If your state falls into this tier, you need a signed collaborative agreement with a licensed physician before you can open your doors. Most malpractice carriers will not issue a policy without one on file, and practicing without it puts your license at risk. Medical Director Co. places a vetted, attorney-reviewed collaborating physician within 24 hours for $799 a month, with no setup fees and no long-term contract.
What NPs Still Need Even in Full Practice States
Full practice authority means your nursing board does not require a physician for standard clinical practice. It says nothing about whether your specific clinic type needs one anyway. Many full practice states still require a physician relationship for certain services, and here is where that most often applies.
- Medspas: Injectables, laser treatments, and other aesthetic procedures often fall under medical board rules that require a medical director, regardless of your NP practice authority.
- Hormone therapy clinics: Prescribing hormone therapy frequently triggers physician oversight requirements that sit outside your nursing board’s scope-of-practice rules.
- IV hydration clinics: Compounded medications and certain infusion protocols can require a physician on record under state pharmacy or medical board law.
- GLP-1 weight loss clinics: Prescribing GLP-1 medications often requires a documented physician relationship, even in states where your general prescribing authority is unrestricted.
Nursing board licensure and medical board oversight of clinic operations are two separate systems, and they do not always move in step. An NP in a full practice state can be fully licensed to practice independently and still need a physician relationship to legally operate one of these clinic types. Check both your nursing board’s rules and your state’s medical practice law before you finalize your service menu, not after you have already signed a lease.
How Your Service Menu Affects the Physician Requirement
Practice authority tier is one variable in whether you need a physician. Your service menu is the other, and it applies no matter which tier your state falls into. These are the factors that most often trigger a physician requirement regardless of your state’s classification.
- Prescription medications: Controlled substances and GLP-1 medications often require a documented physician relationship, even in states with otherwise broad NP autonomy.
- Delegated medical procedures: Injectables, laser treatments, and IV therapies frequently fall under medical board rules rather than nursing board rules.
- Medspa-specific state requirements: Some states require a medical director for aesthetic clinics regardless of your general practice authority status.
- Additional staff: Employing other NPs or physician assistants who need oversight themselves adds a compliance layer that a solo full practice NP would not otherwise face.
Before you finalize your business plan, check your service menu against both your nursing board’s rules and your state’s medical board rules. The Small Business Administration can help with the general startup process, like registering your business and getting funding. But it won’t tell you whether your services need a physician. Answer that question before you sign a lease, not after.

FAQ
Can a nurse practitioner open their own practice in 2026?
Thirty states, Washington, D.C., and two U.S. territories grant full practice authority, letting an NP open and run a clinic without a physician. Everywhere else, an NP needs a signed collaborating physician agreement before opening. Check your state’s classification first, since it determines your entire path to ownership.
What states allow NPs to practice independently?
Full practice states include Alaska, Arizona, Colorado, Connecticut, Delaware, Hawaii, Idaho, Iowa, Kansas, Maine, Maryland, Massachusetts, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wyoming, Washington, D.C., Guam, and the Northern Mariana Islands. Several of these states still require a one-time transition period or supervised-hours threshold before full independence kicks in. See the full breakdown above for reduced and restricted states.
Do NPs need a collaborating physician to open a practice?
Reduced and restricted practice states require a signed collaborating physician agreement before an NP can open at all. Full practice states don’t require one at the nursing board level. Certain clinic types, like medspas or hormone therapy clinics, can still require a physician under separate medical board rules.
Can an NP open a medspa without a physician?
Medspa ownership depends on both your state’s practice tier and the specific services you offer. Injectables, laser treatments, and prescription-based services often fall under medical board oversight rules, separate from your general NP scope of practice. That requirement can apply even in full practice authority states.
How do I find a collaborating physician to open my NP practice?
Medical Director Co. matches nurse practitioners with vetted, licensed collaborating physicians, typically within twenty-four hours. Every placement comes with an attorney-reviewed agreement before either party signs. The flat monthly rate covers the match and the paperwork, with no separate setup fee.
Locking In Your Physician Requirement Before You Sign
Your state’s practice authority tier tells you whether you need a physician to open at all. Your service menu tells you whether you need one regardless of that tier. Both questions have to be answered before you sign a lease or take your first patient. If you have confirmed your state’s classification and you need a collaborating physician or medical director in place, Medical Director Co. can match you with a vetted physician in 24 hours, with attorney-reviewed paperwork and no long-term contract.
