Starting a Practice While Employed: Contracts to Check

Starting a practice while employed is mostly a matter of paperwork your license already allows — forming an entity, binding malpractice, applying for payer credentialing. What can stop you, or narrow what you are allowed to do, is the employment agreement you signed with your current job. That contract, not your license, is the document to read first.

Most nurse practitioners planning an independent practice focus on the clinical and financial setup and treat the employment agreement as an afterthought they will deal with when they resign. By then the constraints are already set. This post covers the three clauses in a typical clinical employment agreement that decide what you can do while still on payroll: outside-work approval, non-compete, and malpractice and tail coverage.

Is starting a practice while employed even allowed?

In most cases, yes. The expensive, slow milestones in a new practice run on other people's timelines and have nothing to do with your employment status. Forming a PLLC, getting an EIN, building a CAQH profile, and submitting payer applications are administrative steps you can complete while drawing a salary. Payer credentialing alone commonly runs 90 to 120 days with commercial carriers, so starting it while employed is what keeps those months funded rather than draining savings. The full case for that sequencing is in why leaving your W-2 job should be the last step.

Those limits are contractual, and they live in the agreement you already signed. Your employment agreement can require you to disclose outside work and restrict where you practice after you leave. Neither clause stops you from building a practice — each one just shapes how and when. Pull your signed agreement and any employee handbook it references before you form an entity, and read the three areas below with a highlighter.

Do you need your employer's approval to work outside your job?

Often, yes. Many clinical employment agreements contain an outside-employment, outside-activities, or moonlighting clause. These range from a simple duty to disclose outside professional work to a requirement for written approval before you take on any. Some are written broadly enough that forming a professional entity or holding an ownership interest in another practice counts as outside activity you have to report.

Read the clause for three things. First, what triggers it: does it apply only to paid clinical work you perform, or to any ownership or professional interest, which would capture setting up your own PLLC before you see a patient? Second, what it requires: disclosure alone, or advance written approval? Third, whether it names conflicts of interest, which is where an employer objects to you building a practice that competes for the same patients while you are still on their payroll.

The safe path is to disclose early and get any approval in writing. Setting up an entity and credentialing quietly, then discovering the agreement required disclosure, hands your employer a clean breach argument at the exact moment you are trying to leave on good terms. If the clause is ambiguous about whether formation and credentialing count as "outside work," that ambiguity is worth a short conversation with your own attorney rather than a guess.

Can a non-compete stop you from opening your own practice?

It depends heavily on your state and on the date you signed. The federal picture is settled for now: the FTC's 2024 rule that would have banned most non-competes nationwide never took effect. A federal court enjoined it in 2024, and the FTC formally voted to vacate the rule and drop its appeals on September 5, 2025 (opens in new tab). State law governs, and in MA, MD, and CT it is unusually favorable to clinicians.

Massachusetts prohibits non-compete provisions in a nurse's employment or partnership agreement outright. M.G.L. c. 112, § 74D (opens in new tab) bars them for nurses registered by the Board of Registration in Nursing, which includes nurse practitioners, and there is no signing-date cutoff. A non-compete in a Massachusetts NP's contract is generally unenforceable regardless of when it was signed.

Connecticut limits, rather than bans, non-competes for advanced practice registered nurses. Under Public Act 23-97, effective October 1, 2023 (opens in new tab), an APRN non-compete cannot exceed one year in duration or a fifteen-mile radius from the APRN's primary practice site named in the agreement, and it must meet several other conditions to be valid. This applies only to agreements entered into, amended, extended, or renewed on or after October 1, 2023. An older Connecticut agreement is judged under the prior, less protective standard, so the date on your contract matters.

Maryland changed most recently. For healthcare professionals who provide direct patient care and earn total annual compensation of $350,000 or less, non-competes are unenforceable, effective for agreements entered on or after July 1, 2025 (opens in new tab). For those earning more than $350,000, a non-compete is unenforceable if it runs longer than one year or reaches more than ten miles from the professional's principal place of employment. The law is not retroactive, so an agreement signed before July 1, 2025 is not covered by it.

Where a non-compete is valid and enforceable, its radius is what determines where you can open. A fifteen-mile Connecticut restriction or a ten-mile Maryland one is measured from your current employer's site, so putting your new practice outside that radius can be the difference between a clean opening and a fight. In Massachusetts the question is generally moot for nurses. Because enforceability turns on the exact wording and date of your agreement, confirm your own situation with a Connecticut, Maryland, or Massachusetts employment attorney before you commit to a location; the summaries above are the current state of the law, not advice about your specific contract.

Does your hospital's malpractice insurance cover your own practice?

No. An employer's professional liability policy covers the care you deliver for that employer, within the scope of your employment. Patients you see through your own PLLC are outside that policy entirely, so you need your own malpractice coverage, bound to your new entity and naming it as an insured, before you see a single patient in the practice. Check your employer's certificate for the scope of what it covers rather than assuming it follows you; it almost never does.

Leaving a W-2 job raises a second question if your employer's policy is written on a claims-made basis, which most hospital and group policies are. A claims-made policy only responds to a claim if the policy is active both when the care happened and when the claim is filed. When you leave, that coverage stops, and any claim that arrives later about care you already delivered has nothing to respond to unless you buy tail coverage to extend the reporting window. Tail is a one-time cost that typically runs 150% to 300% of the annual premium, and who pays for it is a term you want settled in writing before your last day. The full breakdown of claims-made versus occurrence policies and when tail applies is in the guide to malpractice insurance for nurse practitioners.

For the setup phase, the timing is simple: buy your own policy around the time you form your entity, because credentialing applications generally require proof of active coverage. Your new coverage and your employer's coverage solve two different problems, and you will carry both for a while.

What can you finish before you give notice?

Nearly all of the slow work, once the contract questions above are settled. You can form the entity, get your EIN, bind your own malpractice, build and attest your CAQH profile, and submit payer applications while still employed. You can also check whether you can see patients before credentialing is complete, and map the full credentialing timeline so you know how early to start. Give notice when that work is done and your remaining risk is timing rather than whether the practice can function.

Frequently asked questions

Can you start a nurse practitioner practice while still employed?

Usually yes. Forming an entity, binding your own malpractice, and applying for payer credentialing are paperwork milestones your license allows while you are still on a W-2. What restricts you is your employment agreement, not your nursing license — so the real work before you start is reading your contract for outside-work approval and non-compete terms.

Do you need your employer's permission to start a practice on the side?

Often, yes. Many clinical employment agreements contain an outside-employment or moonlighting clause requiring you to disclose and sometimes get written approval for outside professional work. That clause usually governs your setup phase, when you are forming an entity and credentialing but not yet seeing patients. Read it before you file anything, and keep any approval you get in writing.

Can a non-compete stop a nurse practitioner from opening a practice in Massachusetts, Maryland, or Connecticut?

It depends on the state and on when you signed. The federal FTC ban never took effect, so state law governs. Massachusetts prohibits non-competes in nurse employment agreements with no signing-date cutoff. Connecticut caps APRN non-competes at one year and fifteen miles, but only for agreements entered, amended, or renewed on or after October 1, 2023. Maryland bans them entirely for direct-care clinicians earning $350,000 or less, but only for agreements entered after July 1, 2025.

Does your hospital's malpractice insurance cover a practice you run on the side?

No. An employer's professional liability policy covers care you deliver for that employer, within the scope of your job. Patients you see through your own practice are outside that policy, so you need your own coverage bound to your new entity before you see a single patient. If your employer's policy is claims-made, leaving it also raises a separate tail-coverage question.
