This guide is for practice owners, clinic managers, medical directors, and HR teams at behavioral health organizations who need temporary PMHNP coverage. The regulatory points below reflect the rules as of October 2026, so confirm each with the board or government agency that sets it.
Locum tenens PMHNP coverage, booked through a staffing agency or a direct contract, fills a gap with an end date, such as a leave, a vacancy while you recruit, a new service, or a seasonal peak. Either way, put malpractice and tail coverage, credentialing, notice periods, and conversion terms in writing, and start licensing and payer enrollment early. As of October 2026, Medicare's locum tenens billing arrangements are written for physicians and some physical therapists, so enroll a locum PMHNP in Medicare as you would a permanent hire.
When Locum Coverage Makes Sense
The National Association of Locum Tenens Organizations (NALTO), a professional association of temporary physician staffing firms, says health care facilities benefit from locum tenens contracts by covering gaps in patient care during periods of growth or physician shortage (NALTO). For a PMHNP role, consider locum coverage in these situations:
- Leave coverage. A locum covers the panel during a parental, medical, or military leave or a sabbatical.
- Vacancy coverage. A locum keeps appointments, refills, and referrals moving while you recruit.
- New services. A new site, telehealth line, or program can open with locum coverage while you confirm demand.
- Seasonal demand. If your referral data shows predictable peaks, short assignments can cover them without a year-round salary.
Locum coverage fits less well when patients need one prescriber over the long term or when the gap will end before licensing and credentialing can be completed.
Two Ways to Arrange Coverage
Through a Locum Tenens Staffing Agency
NALTO describes locum tenens clinicians, most commonly physicians, as contracting with recruitment agencies to perform medical services for a health care organization over a set period. In its description, the physician works as an independent contractor paid through the staffing agency, and the facility pays the agency (NALTO). Its checklist for choosing a firm asks whether the firm offers services to make sure licensure, credentialing, hospital privileges, and travel and housing arrangements are in place when the physician arrives to work (NALTO).
These NALTO pages are written about physicians, so ask each locum tenens agency you consider which of these tasks it will handle for a nurse practitioner, and get every rate and fee in writing.
Contracting a PMHNP Directly
Hiring a locum psychiatric nurse practitioner directly means you find the clinician yourself, through a job posting or referrals, and sign an independent contractor or short-term employment agreement. Your practice then verifies credentials, arranges malpractice coverage, and pays the PMHNP.
Worker classification also becomes your decision. As of October 2026, the IRS groups the evidence of control and independence into three categories: behavioral, financial, and the type of relationship. It says the keys are to look at the entire relationship and to consider the extent of the right to direct and control the worker. A business that classifies an employee as an independent contractor without a reasonable basis may be held liable for employment taxes for that worker. Either the business or the worker can file Form SS-8 to have the IRS officially determine the worker's status (IRS). Check your state's rules as well, and see our 1099 vs. W-2 guide for employers.
What to Ask a Locum Tenens Agency
Settle these in writing before the agency presents candidates.
- Malpractice and tail coverage. Ask who carries the policy that covers the PMHNP's work for you, what its limits are, which states it covers, and whether it is written on an occurrence or a claims-made form. NALTO's checklist asks whether a firm provides malpractice insurance for the physicians it places (NALTO). The National Association of Insurance Commissioners (NAIC) describes a claims-made form as one that pays only if both the event that triggers the claim and the claim itself are submitted to the insurer during the policy term (NAIC). For a claims-made policy, ask who pays for tail coverage when the assignment ends. See also our guide to malpractice insurance for employers.
- Credentialing. Ask what the agency verifies (licenses, board certification, DEA registration, NPI, and exclusion status), whether it checks each item with the issuing source, and whether its file meets your credentialing policy. On exclusions, the HHS Office of Inspector General says excluded individuals can receive no payment from federal health care programs for items or services they furnish, order, or prescribe, and that anyone who hires one may be subject to civil monetary penalties (OIG).
- Employment status. Ask whether the PMHNP is the agency's employee or its independent contractor.
- Conversion or buyout terms. Ask whether hiring the PMHNP permanently triggers a fee, how the fee is calculated, whether it declines over time, and how long it applies after the assignment ends.
- Notice periods. Ask how much notice each side must give to end, shorten, or extend the assignment, whether a cancellation fee or guaranteed hours apply, and how quickly the agency replaces a PMHNP who leaves early.
Licensure and Credentialing Lead Times
Start licensing and enrollment the day the agreement is signed.
State License and Collaborative Agreement
As of October 2026, the Nurse Licensure Compact says nurses are required to be licensed in the state where the patient is located at the time service is provided, and that an APRN must hold an individual APRN license in each state of APRN practice (NLC). A locum licensed only in another state therefore needs an APRN license in your patients' state before the first visit. If your state requires a collaborative or supervisory agreement for nurse practitioner practice, name the clinician who will fill that role and confirm with the board of nursing what must be in place before the locum starts. Our practice authority map shows each state's classification, and our collaborative agreement guide explains what these agreements cover.
DEA Registration
As of October 2026, the DEA requires that all of a state's licensing requirements be met before it issues a registration in that state, and a practitioner with a practice location in more than one state needs a separate registration in each (DEA). Within one state, DEA rules do not require a separate registration for an office where a practitioner registered at another location in that state only prescribes and keeps no controlled substance supplies (21 CFR 1301.12). Confirm your setup with the DEA.
Payer Enrollment
As of October 2026, Medicare counts nurse practitioners among non-physician practitioners (42 CFR 424.518). For non-physician practitioners, billing privileges take effect on the later of two dates: the filing date of an enrollment application that a Medicare contractor approves, or the date the PMHNP first began furnishing services at a new practice location (42 CFR 424.520). If circumstances prevented enrolling in advance, Medicare allows billing for services at the enrolled practice location up to 30 days before the effective date, but only if all program requirements, including state licensure, were met (42 CFR 424.521). Ask each commercial plan for its processing time, and see our credentialing guide for the enrollment steps.
Medicare Billing for a Locum PMHNP
As of October 2026, the CMS Medicare Claims Processing Manual makes fee-for-time compensation arrangements (formerly called locum tenens arrangements) available to physicians and, under the 21st Century Cures Act, to physical therapists furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area (CMS Medicare Claims Processing Manual, chapter 1, section 30.2.11). Under these arrangements, a regular physician who is unavailable bills, with the Q6 modifier, for the services of a substitute physician whom the regular physician pays on a per diem or similar fee-for-time basis. The manual does not extend these arrangements, or the reciprocal billing arrangements in section 30.2.10, to nurse practitioners.
Plan instead on the same Medicare enrollment you would use for any PMHNP. As of October 2026, all reassignment actions are reported on the CMS-855I. A reassignment of benefits lets an eligible organization or group submit claims and receive payment for the Medicare Part B services that a practitioner provides as a member of that organization or group. Both the practitioner and the organization or group must be enrolled, or enrolling at the same time, before the reassignment takes effect, and a practitioner may reassign benefits to more than one organization or group. When the assignment ends, terminate the reassignment with your final claims in mind: after a termination's effective date, reassigned claims for the practitioner's services are no longer paid to the organization or group (CMS-855I).
As of October 2026, Medicare may pay a clinician's employer when the clinician must turn over fees as a condition of employment. It may also pay an enrolled entity that has a contractual arrangement with the clinician under which the entity bills for the clinician's services. In that case, the entity and the clinician are jointly and severally responsible for any Medicare overpayment to the entity (42 CFR 424.80). If an agency employs the PMHNP, ask your Medicare Administrative Contractor how to set up the reassignment, and ask each commercial plan in writing how it handles a temporary nurse practitioner.
Continuity of Care and Handoffs
A locum PMHNP takes over patients mid-treatment and hands them back on a set date, so plan both handoffs.
- Before the first visit. Write a summary for each active patient, starting with those at higher risk, that covers diagnoses, current medications, recent changes, monitoring due, controlled substance agreements, and pending prior authorizations. Set up EHR access, e-prescribing (including controlled substances if needed), and access to the state prescription drug monitoring program. Review crisis protocols, name a clinical contact, and tell patients who will see them and for how long.
- During the assignment. Keep each patient with the same locum where you can, hold regular case reviews, and track open items in one shared list: pending results, prior authorizations, and patients who need close follow-up.
- When the assignment ends. Get a written handoff to the returning or permanent clinician covering medication changes and open items, bridge refills to the next scheduled visit, and arrange a short overlap or call between the clinicians where you can. Then close system access, terminate the Medicare reassignment, and update each payer.
Locum Tenens vs. Permanent Hire
| Locum coverage | Permanent hire | |
|---|---|---|
| Fits | A gap with an end date | Ongoing demand and long-term patients |
| Commitment | Ends on the agreed date, subject to the notice terms | Open-ended, under the employment agreement |
| What you pay | The fees in the agency agreement or direct contract | Pay, benefits, employer payroll taxes, and recruiting costs |
| Earliest start | Set by licensure, credentialing, and payer enrollment | Set by the same steps, after recruiting |
| Credentialing | Repeats with each new locum | Done at hire, then at each recredentialing cycle |
| Continuity | A handoff at each end of the assignment | Builds on a stable panel |
The two can run together: a locum can hold the panel during the permanent search, and the conversion terms determine whether hiring that locum carries a fee. For the full budget of a permanent hire, see our guide to the cost to hire a PMHNP. For current advertised pay, see our salary guide.
