OAR 851-052-0010 frames physician consultation/referral as the CRNA's own professional judgment call, not a requirement, and OAR 851-052-0060 (office-based anesthesia care) imposes no physician proximity/availability standard. Oregon opted out of the CMS Medicare physician-supervision requirement for CRNAs (governor's letter, 2001) — confirm current opt-out status before relying on this for Medicare billing purposes specifically.

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

No physician proximity/availability requirement is codified for CRNA practice, including office-based anesthesia (OAR 851-052-0060).

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

'separateAgreementRequired' reflects the optional Board prescriptive-authority application, not a physician agreement — no physician sign-off is involved.

Written agreement

Not required

Unconditional under Oregon licensure law — no statute or Board of Nursing rule requires a CRNA to hold a physician supervision or collaboration agreement to practice. (A facility's own credentialing/billing rules, or Medicare Conditions of Participation, may still require physician involvement — that is a facility/payer requirement, not a state licensure one.)

Practice ownership (corporate practice of medicine)

Licensee-only ownership required — ORS 58.376's joint physician/PA/NP professional-corporation ownership pathway names only physicians, PAs, and 'nurse practitioner' licensees — CRNA is a separate license category under ORS 678.010, not a nurse-practitioner population focus, so it is unclear whether a CRNA independently qualifies as an ORS 58.376 licensee. This is an inference from statutory omission, not a confirmed holding — treat as an open item. Absent that pathway, a CRNA-involved entity likely defaults to the physician-majority PC under ORS 58.375.

Not independently confirmed against Board of Nursing or Medical Board guidance in this research pass.

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.
