How to Start a PMHNP Private Practice: A Step-by-Step Checklist for Psychiatric Nurse Practitioners

To start a PMHNP private practice, confirm your state’s practice authority rules, form your business and get a tax ID, set up your NPI, DEA registration and malpractice coverage, choose an EHR with e-prescribing, complete your CAQH profile, and apply to insurance plans 4 to 6 months before you want insured patients. Credentialing is the longest step, often 90 to 180 days, so many PMHNPs open with self-pay patients and add insurance as each plan approves them.

Demand for psychiatric prescribers is high in almost every state, which makes private practice a realistic path for psychiatric mental health nurse practitioners. The clinical work is familiar. The business steps, such as entity setup, prescribing registrations, insurance enrollment and billing, are where most new practices lose time and money. This checklist puts those steps in order. Psychiatrists (MD or DO) can follow our psychiatry private practice guide.

The checklist at a glance

Step	What to do	Typical time
1	Confirm your state’s practice authority and prescribing rules	1 to 2 weeks
2	Form your business, get an EIN and open a business bank account	1 to 3 weeks
3	Set up NPI, DEA, state controlled substance and PDMP registrations	2 to 8 weeks
4	Get malpractice and business insurance	1 to 2 weeks
5	Choose an EHR with e-prescribing and telehealth	1 to 2 weeks
6	Complete CAQH and apply to insurance plans	90 to 180 days
7	Plan telehealth and each additional state: licenses, DEA, payers	90 to 180 days per state
8	Set your fees, policies and HIPAA basics	1 to 2 weeks
9	Set up billing and send your first claims	When each plan approves you

Several steps run at the same time. The order that matters most: start credentialing as early as you can, because it takes the longest.

Step 1: Check your state’s practice authority

Your state decides how independently you can practice and prescribe.

Practice environment	What it means for a PMHNP practice
Full practice	You can evaluate, diagnose, treat and prescribe independently. Some states require a transition-to-practice period first.
Reduced practice	A collaborative agreement with a physician is required for at least one part of practice, often prescribing.
Restricted practice	Physician supervision or delegation is required for one or more parts of practice.

Roughly half of states, plus Washington, D.C., now grant full practice authority, and the list changes almost every year. Check the current status with your state board of nursing and the AANP state practice environment map before you sign a lease or apply to insurance plans. Our PMHNP requirements by state tool shows each state’s category and links to its official board of nursing.

Example: Georgia. Georgia requires a written nurse protocol agreement with a delegating physician who practices in a comparable specialty. Georgia expanded what physicians can delegate to APRNs in 2024, so confirm current prescribing rules with the Georgia Composite Medical Board.

If you need a collaborative or supervising physician, put the agreement in writing before you apply to insurance plans. Payers ask for it, and a missing agreement is a common reason applications are returned.

Step 2: Form your business

• Choose a business structure. Many PMHNPs form a PLLC or LLC. Some states limit who can own a professional entity or which entity type nurse practitioners can use, so check your state’s rules or ask a local attorney.
• Get an EIN (federal tax ID) from the IRS. It is free.
• Open a business bank account and keep practice money separate from personal money.
• Register with your state and city or county as required, including any business license.

Step 3: Set up your provider numbers and prescribing registrations

• Individual NPI (Type 1) with the psychiatric/mental health nurse practitioner taxonomy, 363LP0808X. Make sure your NPPES address and taxonomy match what you will put on insurance applications.
• Group NPI (Type 2) if you will bill under your business’s tax ID. Some payers want the group NPI and a group contract; others let a solo NP bill under the individual NPI with the business tax ID.
• DEA registration in each state where you will prescribe controlled substances, tied to an address in that state.
• State controlled substance registration, if your state requires one in addition to DEA.
• PDMP account in each state where you prescribe controlled substances.
• Electronic prescribing of controlled substances (EPCS). Many states and Medicare Part D require controlled substance prescriptions to be sent electronically, so choose an EHR or e-prescribing tool that supports EPCS.

Step 4: Get insurance for the practice

• Malpractice (professional liability) insurance in your own name, covering the states and services you will provide, including telehealth. Many insurance plans ask for limits of $1 million per claim and $3 million aggregate; check each plan’s requirement.
• General liability insurance if you rent office space.
• Cyber liability insurance is worth considering because you will store patient records.

Step 5: Choose your EHR and telehealth tools

For a psychiatric practice, look for an EHR that includes:

• E-prescribing with EPCS
• Psychiatric note templates and E/M documentation
• Built-in telehealth, or a HIPAA-compliant video tool that will sign a BAA
• Insurance claims and ERA support, or easy access for your billing company
• Patient portal, intake forms and reminders

Common choices for psychiatry and PMHNP practices include Osmind, Valant, SimplePractice, Tebra and AdvancedMD.

Step 6: Get credentialed with insurance plans

This is the longest step. Start it as soon as your NPI, malpractice and business details are final.

1. Complete your CAQH ProView profile and attest it. See our CAQH guide.
2. Pick your payers. Look at which plans your target patients have. In many areas, a few commercial plans and Medicare cover most adult patients.
3. Watch for behavioral health carve-outs. Many health plans send mental health to a separate company (for example Optum, Carelon or Evernorth), which needs its own application.
4. Enroll in Medicare through PECOS if you will see Medicare patients. Medicare pays nurse practitioners 85% of the physician fee schedule.
5. Enroll in Medicaid if you will see Medicaid patients. In Georgia, see our Georgia Medicaid credentialing guide.
6. Follow up every week until each plan sends a signed contract and an effective date.

PMHNP credentialing often takes 90 to 180 days end to end. See how long credentialing takes, by payer and our full PMHNP credentialing guide.

Step 7: Telehealth and practicing in more than one state

Many PMHNP practices see patients by telehealth in several states. The rule that decides everything: the patient’s location at the time of the visit sets the requirements, not where you sit.

For each additional state, you generally need:

Requirement	What it means
RN and APRN license in that state	An APRN license requires an RN license valid in that state. A multistate RN license under the Nurse Licensure Compact covers the RN part in member states, but you still need a separate APRN license. The APRN Compact, which would allow a multistate NP license, is not in effect yet.
That state’s practice rules	If the state is reduced or restricted practice, you need a collaborative or supervising physician who meets that state’s rules, even if your home state is full practice.
DEA registration in that state	Required to prescribe controlled substances to patients located there, plus any state controlled substance registration and a PDMP account.
Credentialing with that state’s payers	Insurance networks are organized by state or market, and Blue Cross Blue Shield plans are separate companies in each state. Each state is its own credentialing project, often 90 to 180 days.
That state’s Medicaid program	Only if you will see Medicaid patients there. Each state runs its own enrollment.
Malpractice coverage for that state	Confirm your policy covers patients located in every state you serve.
Business registration	If you have staff, an office or other presence in that state, your business may need to register there. Ask your accountant or attorney.
That state’s telehealth rules	Consent, prescribing and documentation rules differ. Some states have stricter rules for prescribing certain medications.

Controlled substances by telehealth. Federal telemedicine flexibilities currently allow DEA-registered practitioners to prescribe controlled substances by telehealth without a prior in-person visit through December 31, 2026. A permanent rule has not been finalized, and state rules can be stricter.

How to expand without losing months:

• Start with one or two states where most of your patients are and where your payers are open.
• Add states one at a time, and start credentialing for the next state 4 to 6 months before you want to see insured patients there.
• Keep a tracker for every state: license, DEA, CAQH, payer applications, effective dates and renewal dates.
• Bill telehealth correctly. Payers use different place-of-service codes and modifiers. See POS 02 vs 10 and modifier 95.

Real example: we have run credentialing and billing for a telehealth psychiatry practice in 23 states, with more than 100 payer enrollments over 3 years. See also the multi-state section of our PMHNP credentialing guide.

Step 8: Fees, policies and HIPAA

• Self-pay rates for evaluations and follow-ups, based on your local market.
• Good Faith Estimates. Under the No Surprises Act, uninsured and self-pay patients are generally entitled to a Good Faith Estimate of expected charges.
• Office policies: cancellations, no-shows, controlled substance agreements, refills and after-hours contact.
• HIPAA basics: a risk assessment, written policies, and a business associate agreement (BAA) with every vendor that handles patient information, including your EHR, telehealth tool and billing company.

Step 9: Billing and your first claims

The codes most PMHNP practices bill:

Code	What it is
90792	Psychiatric diagnostic evaluation with medical services
99202 to 99205	New patient office visits (E/M)
99212 to 99215	Established patient office visits (E/M)
90833, 90836, 90838	Psychotherapy add-ons with an E/M visit
90785	Interactive complexity add-on, when it applies

Most medication-management follow-ups use an E/M code, with a psychotherapy add-on when you also provide documented psychotherapy. See billing 99214 with 90833, 90791 vs 90792 and incident-to billing for PMHNPs.

Before your first insured visit, confirm each plan’s effective date, set up electronic claims, ERA and EFT, and verify every patient’s benefits, including behavioral health carve-outs.

A realistic timeline

When	What to do
4 to 6 months before opening	Confirm practice authority, form the business, get EIN and NPI, start CAQH and credentialing
3 months before	DEA and state registrations, malpractice insurance, collaborative agreement if needed, choose EHR
1 month before	Set fees and policies, set up telehealth, test e-prescribing, set up billing
Opening	See self-pay patients, and insured patients for plans that have approved you
First 6 months	Add remaining plans as they approve you; review collections and denials monthly

Common mistakes

• Starting credentialing too late, then waiting months for insured patients.
• Seeing insured patients before the effective date, which leads to out-of-network denials.
• Missing behavioral health carve-outs, so claims go to the wrong company.
• No DEA registration in a telehealth state where you prescribe controlled substances.
• NPI, taxonomy or address mismatches between NPPES, CAQH and applications.
• Billing an E/M visit and a psychotherapy add-on without separate documentation for each.

This guide is general information, not legal, tax or clinical advice. Practice authority, prescribing and telehealth rules change, so confirm current requirements with your state board of nursing, the DEA and each payer before you act.
