Supervision Agreement for Certified Nurse-Midwives in Oklahoma
Yes, a written supervising-physician agreement is required. Oklahoma does not name a specific instrument.
This research pass found CNM grouped with CNP/CNS under H.B. 2298 in secondary summaries of the 2025 reform, but could not independently confirm CNM-specific statute text (as opposed to the general APRN framework) — treat the exact threshold and any CNM-specific carve-out as unconfirmed.
Independent practice requires: ≥6,240 hours of supervised clinical practice, then Board of Nursing approval — secondary sources describe CNM as covered by the same H.B. 2298 (2025) framework as CNP/CNS.
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)
Coded the same as general NP pending CNM-specific confirmation.
after Board approval of independent prescriptive authority: No proximity requirement
No ongoing proximity/availability requirement once independent.
Supervision ratio
Not codified — no cap on file
Chart review
Not codified — left to the agreement
Meeting cadence
Not codified — left to the agreement
Prescriptive authority
Separate prescribing terms required · controlled substances permitted
Coded the same as general NP — Schedule I–II excluded, Schedule III–V limited to a 30-day supply — pending CNM-specific confirmation.
Written agreement
Required
Coded the same as general NP — required only below the 6,240-hour threshold, per secondary sources; not independently confirmed for CNM specifically.
Practice ownership (corporate practice of medicine)
Non-licensee ownership permitted — Same as the general CPOM note above — Oklahoma has no CPOM doctrine.

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).
