Collaborative Practice Agreement for Certified Nurse-Midwives in Oregon
No. Certified Nurse-Midwives practice independently here. Oregon does not require one.
Certified nurse-midwife is a population focus under the single NP license (OAR 851-050-0005(9)(e)) — Oregon has no separate CNM license or statute. CNMs independently provide care across pregnancy, childbirth, postpartum, newborn, family planning, and gynecologic needs, under the same FULL-independence framework as general NPs.
What the collaboration must look like
The rules the physician relationship has to follow. Each fact comes from the statute or board rule listed under sources.
Proximity
No proximity requirement
Same standard as general NPs — no physician availability/proximity requirement is codified.
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
Covered by the practice agreement · controlled substances permitted
Same statutory framework as general NPs (ORS 678.390, OAR division 56), scoped to the CNM population focus (obstetric/gynecologic and newborn care).
Written agreement
Not required
Unconditional — same as general NPs; no separate CNM statute imposes a physician agreement requirement.
Practice ownership (corporate practice of medicine)
Licensee-only ownership required — Same as the general `np` entry — professional corporation under ORS 58.376, since CNM is an NP population focus rather than a distinct license category.

About Oregon's rules
Oregon has no physician-supervision requirement for NP/CNS/CRNA and replaced PA 'supervision' with a non-supervisory 'collaboration agreement' (ORS 677.495-677.525, recodified by H.B. 4010, eff. June 6, 2024). CNM and PMHNP are population foci under the single NP license (OAR 851-050-0005), not separate license categories. CRNA/CNS entity co-ownership with physicians is unconfirmed — ORS 58.376 names only physicians, PAs, and NPs.
