PMHNP · Oklahoma
Supervision Agreement for Psychiatric Mental Health Nurse Practitioners in Oklahoma
Yes, a written supervising-physician agreement is required. Oklahoma does not name a specific instrument.
Secondary sources describing H.B. 2298 (2025) list 'CNP, CNS, and CNM' together as covered by the reform without carving out PMHNPs specifically — this project reads that as PMHNPs (a CNP population focus) following the identical general-NP framework, not a separate PMHNP-specific rule, but that inference wasn't confirmed against primary statute text naming PMHNPs.
Independent practice requires: ≥6,240 hours of supervised clinical practice, then Board of Nursing approval — identical threshold to general NP under H.B. 2298.
What the supervision must look like
The rules the physician relationship has to follow. Each fact comes from the statute or board rule listed under sources.
Proximity
below the 6,240-hour independent-prescriptive-authority threshold: Available remotely (no on-site requirement)
Same standard as general NPs.
after Board approval of independent prescriptive authority: No proximity requirement
No ongoing proximity/availability requirement once independent.
Supervision ratio
below the 6,240-hour independent-prescriptive-authority threshold: Up to 6 at a time (combined across provider types)
Same combined 6-PA/NP cap under OAC 435:10-13-2 as `pa`/`np` above, with the same post-reform-applicability caveat.

Prescriptive authority
Separate prescribing terms required · controlled substances permitted
Psychiatric prescribing in practice skews toward Schedule III–IV stimulants and benzodiazepines/hypnotics more heavily than general primary-care NP prescribing — not a different legal limit, reflected only in calculatorWeights below.
Written agreement
Required
Same as general NP — required only below the 6,240-hour threshold for prescriptive authority.
Practice ownership (corporate practice of medicine)
Non-licensee ownership permitted — Same as the general `np` entry — Oklahoma has no CPOM doctrine.

Estimate for one Psychiatric Mental Health Nurse Practitioner. This state's proximity rules add a small premium.
About Oklahoma's rules
HB 2298 (APRNs) and HB 2584 (PAs), both 2025 and effective Nov. 1, 2025, created new hours-based independent-practice pathways in a state with no prior pathway for either. Being this recent, secondary sources conflict on whether a 6-provider physician-ratio cap (OAC 435:10-13-2) still applies post-reform — flagged per-provider below rather than guessed. Oklahoma has no corporate-practice-of-medicine doctrine (Okla. A.G. Op. 77-168).
