Informational only, not legal advice. Requirements change, so verify with the Louisiana State 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 Louisiana, which change over time, so confirm your specific situation with the board.
Practice Authority
Louisiana Practice-Authority Category (Reduced Practice)
The American Association of Nurse Practitioners (AANP) currently classifies Louisiana as a reduced practice state. In practice, a Louisiana PMHNP works under a required collaborative relationship with a physician for at least some elements of practice, including aspects of prescribing. Because these designations can change, confirm the current category directly with the Louisiana State Board of Nursing and the AANP map before you rely on it.
Collaboration
Is a Collaborative or Supervisory Agreement Required?
Louisiana generally requires a nurse practitioner to have a collaborative relationship or agreement with a physician for at least some functions before providing the full scope of care. What any 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 Louisiana State Board of Nursing.
Prescriptive Authority
Prescriptive Authority and Controlled Substances
Louisiana 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 Louisiana State 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 Louisiana. Getting paid is a separate track, with its own payer rules, Medicaid program, and enrollment timelines. We cover that in detail on the Louisiana credentialing and payer enrollment page, and nationally in our PMHNP credentialing guide.
