PMHNP Practice Requirements In Oklahoma: Scope, Prescribing & Collaboration
Short answer: AANP lists Oklahoma as restricted practice, so a PMHNP prescribes under a written supervision agreement with an Oklahoma licensed physician until the Board grants independent prescriptive authority after 6,240 clinical practice hours with supervised prescriptive authority (59 O.S. § 567.4a; § 567.4c, effective November 1, 2025). No APRN may prescribe Schedule II, even with independent authority, and Schedule III through V prescriptions are capped at a 30 day supply (63 O.S. § 2-312(C); OAC 485:10-16-5).
Oklahoma PMHNP Rules At A Glance
| Topic | Oklahoma Rule |
|---|---|
| Practice authority | Restricted practice on the AANP map. Prescriptive authority runs through a supervising physician until the Board approves independent prescriptive authority under HB 2298 (59 O.S. § 567.4a; § 567.4c). |
| Physician agreement | A written supervision agreement covering referral, consultation, collaboration and physician availability goes to the Board with your initial and renewal applications; changes are filed within 30 days (59 O.S. § 567.4a(1)). |
| Transition period | 6,240 clinical practice hours with prescriptive authority supervised by a physician, then apply through the Nurse Portal; approved APRNs no longer need a supervising physician or agreement (59 O.S. § 567.4c; Board HB 2298 FAQ). |
| Controlled substances | No Schedule I or II for any APRN, supervised or independent (63 O.S. § 2-312(C); Board Exclusionary Formulary P-50B). Schedule III through V allowed with DEA and OBNDD registration, no more than a 30 day supply (OAC 485:10-16-5). |
| PDMP | Check the Oklahoma PMP at the initial opioid prescription and at least every 180 days after, and document the check in the medical record (63 O.S. § 2-309D; Board Guideline P-55). |
| Regulator | Oklahoma Board of Nursing licenses APRNs and grants prescriptive authority recognition; supervising physicians must be licensed by the State Board of Medical Licensure and Supervision or the Board of Osteopathic Examiners (59 O.S. § 567.4a). |

Practice Authority
Oklahoma Practice-Authority Category (Restricted Practice)
AANP currently classifies Oklahoma as a restricted practice state on its State Practice Environment map. A PMHNP in Oklahoma can’t practice fully independent of a physician relationship, and state law requires supervision, delegation, or team management by an outside health professional for at least one element of practice. Recent legislation created a pathway toward more independent prescriptive authority after an extended period of supervised practice, so the environment is in transition.
The AANP State Practice Environment map and AANP’s practice information by state show how Oklahoma compares with other states. The rules that bind you, though, come from the Oklahoma Board of Nursing and the Oklahoma State Board of Medical Licensure and Supervision.
Collaboration
Is A Collaborative Or Supervisory Agreement Required?
Oklahoma generally requires an NP to practice under supervision, delegation, or a written collaborative arrangement with a physician, and oversight may be shared between the Oklahoma Board of Nursing and the Oklahoma State Board of Medical Licensure and Supervision. State rule sets what the arrangement must contain, how supervision and quality assurance are documented and how often it’s reviewed.
What goes into these agreements is covered in our guide to PMHNP collaborative practice agreements. The PMHNP scope of practice by state overview answers the same questions for every other state.
Prescriptive Authority
Prescriptive Authority And Controlled Substances
Oklahoma NPs who meet the state’s requirements can be granted prescriptive authority, and it can extend to controlled substances once the conditions are met. In Oklahoma, though, some or all prescribing may be tied to the required collaborative or supervisory arrangement. You’ll also need your own federal DEA registration for controlled substances, and some carry additional federal or state conditions. State law and board rule set the specific scope, any limits and the documentation. The U.S. Drug Enforcement Administration handles the federal side, and the Oklahoma Board of Nursing handles the state side.
Next Step
Credentialing Is A Separate Track
None of this gets you paid on its own. Credentialing in Oklahoma is a separate track with its own payer rules, Medicaid program and enrollment timelines, and the Oklahoma credentialing and payer enrollment page covers it in detail. For the national view, see our PMHNP credentialing guide.
Going out on your own? Our guide on how to start a PMHNP practice and the 90-day launch checklist cover licensure, collaboration and enrollment in the order they have to happen. Setting aside money for the launch starts with knowing what PMHNP credentialing costs and what it costs to start a PMHNP practice.
If you want help with the setup itself, First Practice Launch handles payer enrollment, the EHR, portals and billing for a first practice at $6,000, or four monthly payments of $1,500.
FAQ
Frequently Asked Questions
Can A PMHNP Practice Independently In Oklahoma?
It depends on what you mean. Since November 1, 2025, a certified nurse practitioner with 6,240 clinical practice hours under supervised prescriptive authority can apply for independent prescriptive authority, and once approved no supervising physician or agreement is required (59 O.S. § 567.4c). The Board’s FAQ says HB 2298 changed nothing else about scope of practice, and AANP still lists Oklahoma as restricted.
How Many Hours Do I Need For Independent Prescriptive Authority In Oklahoma?
It depends on your record, but the statutory number is 6,240 clinical practice hours with prescriptive authority supervised by a physician (59 O.S. § 567.4c(B)(2)). Hours earned before the law took effect count, and the Board’s FAQ says the supervising physician didn’t have to be Oklahoma licensed, so out of state hours can count too. You also need 45 contact hours or three academic credits in pharmacotherapeutics within the three years before you apply (59 O.S. § 567.4a(3)).
Can A PMHNP Prescribe Adderall In Oklahoma?
No. Schedule II controlled dangerous substances are off limits for every APRN with prescriptive authority, and the Board’s HB 2298 FAQ confirms independent prescriptive authority didn’t change that (63 O.S. § 2-312(C); Exclusionary Formulary P-50B). Schedule III through V are allowed once you hold DEA and OBNDD registration, capped at a 30 day supply (OAC 485:10-16-5).
This is general information, not legal advice. It applies the general nurse practitioner rules in Oklahoma to PMHNPs, and those rules aren’t the same for every role. Rules change, so check with the Oklahoma Board of Nursing, the Oklahoma State Board of Medical Licensure and Supervision, and the AANP State Practice Environment map before you act on it.
