Most nurse practitioners who open their own practices have spent years becoming exceptional clinicians. The preparation is extensive — years of education, supervised practice, board certification, continuing education. What tends to be less prepared is the business.

That gap is not a character flaw. NP programs do not teach practice ownership. There is no standardized curriculum for what it takes to build a financially sustainable independent practice — how to sequence credentialing, what to look for in a payer contract, how to set up billing infrastructure that actually captures the complexity of the care being delivered. Most NPs learn this by doing it, which means learning it through expensive mistakes.

Duet works with NP-owned primary care practices at every stage of growth. What follows is drawn from that experience — the decisions that consistently separate practices that build something durable from those that spend their first two years putting out fires.

Before You Open: Confirm Your State's Practice Authority

This is the first question, because it shapes everything downstream — your business structure, whether you need a collaborating physician agreement, and how commercial payers will credential you.

As of 2026, 27 states plus Washington D.C. grant nurse practitioners full practice authority, meaning independent evaluation, diagnosis, treatment, and prescribing without physician oversight. Another 12 states require a collaborative practice agreement. The remaining states operate under restricted practice models requiring physician supervision.

Your state Board of Nursing is the authoritative source. Look it up before you sign a lease or form an entity.

This matters beyond compliance. In restricted-practice states, some commercial payers will only credential an NP under a supervising physician's NPI — which limits your ability to negotiate independently and establishes a billing structure that affects your revenue for as long as you are in that contract.

Write a Business Plan — A Real One

Not a 40-page document. An honest set of answers to questions that most people skip because the answers are uncomfortable.

Who will your patients be? Your payer mix determines your revenue per visit, which determines how many patients you need to break even. A practice built primarily on original Medicare reimburses differently than one with a commercial-heavy panel, and the operational implications — credentialing timelines, documentation requirements, value-based care eligibility — are different too.

What will it cost to open? Credentialing alone takes 60 to 120 days before you collect your first dollar from most payers. That means rent, EHR costs, malpractice insurance, and personal expenses all need to be covered before revenue stabilizes. Most practices that fail in the first year ran out of runway, not patients.

What does break-even look like? The answer requires knowing your overhead structure and your realistic revenue per visit — which requires knowing your payer mix. Practices that skip this step often discover the math only when it becomes a crisis.

What does growth look like? A solo lifestyle practice and a multi-provider clinic require different infrastructure from day one. Choosing with your intended scale in mind is worth the effort upfront.

Form Your Entity and Get Your NPI

Once your state's practice authority rules are clear, form your business entity — typically an LLC or professional corporation depending on your state — and establish your business bank account, EIN, and malpractice insurance. Keep personal and business finances strictly separate from the beginning. The practices that have the most trouble with financial clarity are the ones that blurred this line early.

You will need a Type 2 NPI — a National Provider Identifier for the practice entity — in addition to your existing Type 1 individual NPI. Both are required for billing. Apply for both before you begin credentialing.

Start Credentialing Earlier Than You Think You Need To

Medicare enrollment through PECOS takes 60 to 90 days. Most commercial carriers take 90 to 120 days. Some state Medicaid programs take longer. These timelines run on the payers' administrative schedules, not yours, and they do not compress no matter how persistently you follow up.

The practical implication: if you want to see insured patients in October, you need to start credentialing in May or June — earlier if your state has complex Medicaid requirements.

CAQH — the universal credentialing database that most commercial payers draw from — requires attestation every 120 days. A lapsed profile can restart the credentialing clock. Create it early and keep it current.

Every month of credentialing delay is revenue you cannot recover. A primary care practice seeing a typical volume of patients at average Medicare primary care rates loses tens of thousands of dollars in potential revenue for every month it cannot bill major payers. This is the most common financial shock for new practice owners, and it is entirely avoidable with earlier planning.

Choose Your EHR for Where You Are Going, Not Where You Are Starting

The EHR decision shapes how you document, how you bill, and whether you can participate in programs like ACO REACH or Medicare Promoting Interoperability. It is also a decision that is genuinely difficult to reverse once you have a built panel — migrating EHRs with active patients is disruptive in ways that are easy to underestimate.

We queried 1,000 NP-owned primary care practices to understand which systems they are running. Tebra is the most common, followed by Athenahealth and eClinicalWorks. The distribution reflects how most NP practices make this decision: based on price and recommendation rather than fit.

Several things are worth knowing before you choose. Not all EHRs are certified under the federal ONC Health IT Certification Program — a requirement for participation in government programs including ACOs. You can verify certification status on the Certified Health IT Product List before you commit. Some platforms bundle billing modules that function adequately at low volume and create revenue problems at scale. Some are inexpensive at launch and become expensive as you grow. And every platform performs differently depending on how it is configured — documentation templates, coding prompts, and billing workflows matter more than the software brand.

The right questions: Is this system ONC-certified? What does the billing module actually do with denials? What does pricing look like at twice my current size? Does this system support the payer mix and patient population I am building toward?

Duet has a partnership with Athenahealth that gives NP practices access to the platform at pricing and with implementation support that is not available independently. If EHR selection is part of your planning, it is worth a conversation.

Get Your Billing Right Before You Open

This is where most NP practices leave money on the table — and most of the time, they do not know it.

The 85% Medicare reimbursement differential for NP-owned practices is structural and not going away in the near term. But a significant portion of the revenue gap between what NP practices bill and what they collect is not structural — it is recoverable. It comes from undercoding visits that legitimately support a higher E&M level, from missing add-on codes for work that is already being performed in the exam room, and from billing infrastructure that catches denials but not the silent underpayment that never generates a denial at all.

Across Duet's network, the average number of add-on codes billed per E&M visit is low — meaning most visits capture no add-ons at all, despite the fact that screenings, assessments, and chronic care coordination are being performed. G2211, the longitudinal care complexity add-on for Medicare primary care visits, is captured inconsistently even among practices that know it exists. The work is happening. The billing is not reflecting it.

Getting this right from the beginning — with documentation templates that support accurate Medical Decision Making capture, a billing workflow that reviews remittances as well as denials, and systematic attention to add-on code utilization — is the difference between a practice that builds equity over time and one that works hard while quietly losing ground.

Who You'll Be Credentialing With

Credentialing priorities vary by state. The payers worth getting in front of first — based on commercial lives in each market — are the ones that will cover the largest share of your potential patient panel. Focusing your credentialing sequencing here avoids the trap of being enrolled with smaller carriers while your panel is ready to grow and the major payers are still pending.

New Hampshire: Elevance Health (Anthem) anchors the commercial market, followed by Point32Health, Cigna, and UnitedHealthcare. WellSense is important for Medicaid-covered patients.

Massachusetts: Blue Cross Blue Shield of Massachusetts is dominant by a wide margin, followed by Point32Health (Harvard Pilgrim and Tufts Health). WellSense and Mass General Brigham Health Plan (AllWays Health) round out the commercial landscape.

Connecticut: Elevance Health (Anthem) leads, followed by UnitedHealthcare, Aetna, and Cigna. The State of Connecticut administers HUSKY Health — the Medicaid program — which is significant volume for primary care practices serving lower-income populations.

New York: Elevance Health, UnitedHealthcare, and Aetna are the three largest commercial carriers by lives. Healthfirst and Excellus BlueCross BlueShield are significant in downstate and upstate markets respectively.

Oregon: Regence BlueCross BlueShield of Oregon leads commercial enrollment, followed by PacificSource, Kaiser, Providence Health Plan, Moda Health, UnitedHealthcare, and Cigna. Oregon's commercial market is more regionally fragmented than most states — getting into Regence and PacificSource first covers the most ground.

Florida: Florida Blue dominates by a significant margin, followed by Aetna, UnitedHealthcare, Humana, and Cigna. Oscar Health has meaningful presence in South Florida. Credentialing with Florida Blue is typically the highest-priority first step for any Florida practice.

Texas: Blue Cross and Blue Shield of Texas leads by a substantial margin, followed by UnitedHealthcare, Aetna, Humana, and Cigna. Baylor Scott & White Health Plan is significant in the DFW market specifically.

A few things worth knowing regardless of state: Medicare enrollment through PECOS is separate from commercial credentialing and should run in parallel, not sequentially. And in states where Medicaid managed care is significant — Connecticut's HUSKY, Oregon's CareOregon, Florida's Medicaid MCOs — those applications often have the longest timelines and the most documentation requirements. Start them early.

Build Your Patient Panel Before Everything Is Perfect

The instinct is to wait — all contracts live, full schedule open, website polished — before seeing anyone. This instinct costs practices more than they realize.

The period before commercial credentialing is complete is not dead time. Transparent cash pricing, reduced-cost initial visits, and in some cases pro bono care for patients who need it serve a function beyond the immediate revenue: they build your panel with people who have experienced your care before you needed anything from them in return.

Early patients become long-term patients with remarkable consistency when the initial experience is good. They become review writers, referral sources, and community advocates. The practices that grow fastest in their second and third years are often the ones that were most generous with access in their first six months.

Your Google Business profile should be active and complete before you see your first patient. It costs nothing, and it is where most prospective patients will look before they decide whether to call. A practice with thoughtful reviews feels established in a way that a practice with none does not, regardless of how good the care is.

What to Expect in Year One

Honest benchmarks, based on what we observe across the practices we work with:

Months one through three are usually harder than projected. Credentialing delays, slower patient volume, cash flow pressure. This is normal. Build for it financially.

Months four through six: the panel starts building. Billing rhythm establishes. First real data on revenue per visit and denial rates — which is when practices either discover their billing infrastructure is working or discover it has been leaking revenue since day one.

Months seven through twelve: practices with solid infrastructure are approaching or at break-even. The ones that struggled in this period almost always had a billing or credentialing problem that started in month one and compounded.

The practices that build durable businesses are not the ones that had the most patients earliest. They are the ones that got their infrastructure right before they opened their doors — and knew what they were walking into.
