Informational only, not legal advice. Requirements change, so verify with the Ohio Board of Nursing and the AANP State Practice Environment map. Last reviewed: July 2026. This page focuses on PMHNPs but reflects general nurse practitioner rules in Ohio, which change over time, so confirm your specific situation with the board.
Practice Authority
Ohio Practice-Authority Category (Reduced Practice)
The American Association of Nurse Practitioners (AANP) currently classifies Ohio as a reduced practice state. In practice, an Ohio PMHNP works under a required collaborative relationship with a physician for at least some elements of practice, most commonly documented as a standard care arrangement. Because these designations can change, confirm the current category directly with the Ohio Board of Nursing and the AANP map before you rely on it.
Collaboration
Is a Collaborative or Supervisory Agreement Required?
Ohio generally requires a nurse practitioner to have a standard care arrangement with a collaborating physician before providing care. What the agreement must contain, how it is documented, and how often it is reviewed are set by state rule and can change, so confirm the current requirements and forms with the Ohio Board of Nursing.
Prescriptive Authority
Prescriptive Authority and Controlled Substances
Ohio nurse practitioners who meet the state’s requirements may be granted prescriptive authority, which in general can extend to controlled substances when the appropriate conditions are met. Controlled-substance prescribing also requires a separate federal DEA registration, and some substances carry additional conditions. Because the specific scope and documentation are governed by state law and board rule, verify current details with the Ohio Board of Nursing and the U.S. Drug Enforcement Administration before prescribing.
Next Step
Credentialing Is a Separate Track
Scope of practice decides how you can practice in Ohio. Getting paid is a separate track, with its own payer rules, Medicaid program, and enrollment timelines. We cover that in detail on the Ohio credentialing and payer enrollment page, and nationally in our PMHNP credentialing guide.
