Oregon collaborating physician requirements reflect a full-practice-authority state for nurse practitioners with a modernized, collaboration-based framework for physician associates. Oregon APRNs, including nurse practitioners, certified nurse-midwives, and clinical nurse specialists, practice independently under the exclusive licensure authority of the Oregon State Board of Nursing under ORS Chapter 678. No physician collaboration agreement, supervising physician, or prescriptive protocol is required for Oregon NP practice or prescribing.
For physicians seeking collaboration income in Oregon, the active statutory framework centers on physician associates, the term Oregon law now uses for what were previously called physician assistants following the title change enacted by HB 4010 in 2024. Oregon modernized its PA practice framework through HB 3036 (2021) and HB 2584 (2023), completing the transition from supervision to collaboration by December 31, 2023. Every Oregon PA must now have a written collaboration agreement in place before practicing, with additional requirements for PAs early in their clinical careers. This guide covers every requirement a physician needs to understand in 2026, sourced directly from ORS 677.495, ORS 677.510, and OAR 847-050.
Oregon Collaborating Physician Overview: Where Oregon Stands
Oregon is a full-practice-authority state for APRNs. The Oregon State Board of Nursing governs APRN practice and prescribing under ORS Chapter 678, and Oregon APRNs function as licensed independent practitioners across all four recognized APRN roles.
Governing Bodies
Two regulatory bodies govern healthcare providers in Oregon:
- Oregon State Board of Nursing (OSBN): Governs APRN licensure, scope of practice, prescriptive authority, and disciplinary matters under ORS Chapter 678 and Oregon Administrative Rules Chapter 851.
- Oregon Medical Board (OMB): Governs physician licensure, physician associate licensure, collaborative practice agreements for PAs, chart review requirements, and disciplinary matters under ORS Chapter 677 and OAR Chapter 847.
The Transition to Collaborative Practice for PAs
Oregon completed a multi-phase transition from physician supervision to physician collaboration for all PAs as follows:
- HB 3036 (2021): Began removing supervision requirements and shifting to collaborative practice
- HB 2584 (2023): Fully implemented collaborative practice for all Oregon PAs
- January 1, 2024: All Oregon licensed PAs required to be operating under a collaboration agreement
The Oregon Medical Board provided a transition FAQ confirming that no PA could practice on or after January 1, 2024 without a written collaboration agreement in place.
NP Practice Authority in Oregon: Full Independence Without a Physician Agreement
Oregon APRNs licensed under ORS Chapter 678 may independently diagnose, treat, and prescribe without any physician involvement under state law. The OSBN issues prescriptive authority as part of APRN licensure for qualified practitioners and the physician’s role in NP practice is not defined by statute or rule as a compliance requirement.
What Oregon APRNs May Do Without a Physician
An Oregon APRN may independently:
- Assess and diagnose patients within their certified scope
- Order and interpret diagnostic tests and laboratory work
- Prescribe legend drugs and pharmacologic treatments
- Prescribe Schedule II through V controlled substances with a valid DEA registration
- Manage acute and chronic conditions independently
- Open and operate independent practices
Collaboration as Good Clinical Practice
Oregon ORS Chapter 678 and OSBN rules reflect that APRNs collaborate with other healthcare providers as a professional standard tied to clinical appropriateness and patient need, not as a regulatory requirement tied to prescribing authority. An Oregon NP who consults a specialist or refers a complex patient to a physician is fulfilling a professional obligation. That obligation does not require a formal written agreement with a specific physician.
Where Physician Collaboration Still Applies: The Physician Associate Framework
Active statutory physician collaboration requirements in Oregon apply specifically to physician associates under ORS 677.510 and OAR 847-050-0082. Every Oregon PA must have a written collaboration agreement in place before practicing medicine, entered into with either a physician or an employer as defined in OAR 847-050-0010(4).
Who Can Sign the Oregon PA Collaboration Agreement
Oregon’s framework distinguishes this state from most others: the collaboration agreement may be signed by a physician or an employer. Under OAR 847-050-0010(4), an employer is defined as a health care entity, including a hospital, medical group, health system, or other licensed healthcare organization, that employs or contracts with the PA.
This means that in Oregon, a large clinic or health system may sign the collaboration agreement as the employer party rather than requiring an individual named physician to sign. In smaller practice settings without institutional employer structures, the agreement is signed by an individual physician.
The Collaborative Practice Agreement Under ORS 677.510 and OAR 847-050-0082
Under OAR 847-050-0082(1), a physician associate may not practice medicine unless the physician associate has entered into a written collaboration agreement signed by a physician or employer as described in the rule.
Filing and Retention
Collaboration agreements are not filed with the Oregon Medical Board before the PA begins practice. Under OMB guidance, collaboration agreements must be kept on file at the PA’s primary location of practice and only made available to the Oregon Medical Board upon request. The physician or employer who signs the agreement must provide a copy to the PA. Both parties should retain accessible copies.
Multiple Agreements
Under OAR 847-050-0082(6), a PA may enter into multiple collaboration agreements for each employer or practice. A PA who works at multiple clinic locations may need a separate agreement for each practice setting.
Agreement Updates
Under OAR 847-050-0082(5), a collaboration agreement must be replaced or amended in writing to add, remove, or change requirements. Verbal understandings or informal changes to the arrangement do not constitute a valid amendment.
What Must Be in an Oregon PA Collaborative Practice Agreement
Under OAR 847-050-0082(2), the collaboration agreement must include, but is not limited to, all of the following:
1. PA Identification
The PA’s name, Oregon license number, and primary location of practice.
2. Physician or Employer Identification
The name of the physician or employer with whom the PA is entering the collaboration agreement.
3. Description of Collaboration Process
A general description of the PA’s process for collaboration with physicians and, if applicable, any differences in the collaboration process based on practice location. This description should reflect how the PA will access consultation, how referrals are made, and how the PA engages with the health care team when the patient’s condition or clinical situation requires it.
4. Performance Assessment Plan (If Required)
If the PA has fewer than 2,000 hours of post-graduate clinical experience, the collaboration agreement must include a plan for consistent and quality collaboration with a specified physician on a regular basis. The requirements and details of this plan are addressed in the next section.
Additional Requirements
Under OAR 847-050-0082(3), the collaboration agreement may include additional requirements specific to the PA’s practice as required by the physician or employer, including additional levels of oversight, limitations on autonomous judgment, and designating a primary contact for collaboration. These optional provisions allow practices to tailor the agreement to the specific clinical context.
The 2,000-Hour Performance Assessment Plan
Oregon’s performance assessment plan is one of the most distinctive features of the state’s PA collaboration framework. It applies to PAs who have not yet accumulated 2,000 hours of post-graduate clinical experience and requires a more structured collaboration structure during that early-career period.
What Qualifies as Post-Graduate Clinical Experience
Under OAR 847-050-0082(2)(d)(A), post-graduate clinical experience means the professional practice as a physician associate applying principles and methods to provide assessment, diagnosis, and treatment of patients. Hours from PA school clinical rotations do not count toward the 2,000-hour threshold.
What the Plan Must Provide
If the performance assessment plan is required, the collaboration agreement must include a plan for consistent and quality collaboration with a specified physician on a regular basis. The plan must:
- Identify a specific named physician with whom the PA will regularly collaborate
- Describe how that collaboration will occur, including the frequency and method
- Be documented in the collaboration agreement
Under OAR 847-050-0082(2)(d)(C), collaboration with the specified physician during the performance assessment period may occur in person and through synchronous and asynchronous technology.
Tracking Responsibility
Under OAR 847-050-0082(2)(d)(D), the PA, or the physician or employer with whom the PA has entered into the collaboration agreement, is responsible for tracking the 2,000 hours of post-graduate clinical experience to determine when the plan is no longer required. When the PA reaches 2,000 hours, the plan requirement ends and the collaboration agreement must be amended in writing to remove or modify the plan.
Why This Matters for Physicians
A physician who signs a collaboration agreement that includes a performance assessment plan is committing to regular, specific collaboration with the PA during that early-career period. The regularity and documentation of that collaboration are not optional features of the plan. They are its substance. A physician who signs the agreement but provides no meaningful regular collaboration during the performance assessment period is not fulfilling the obligation the plan creates.
Physician and Employer Eligibility in Oregon
Physician Eligibility
A qualifying Oregon physician must hold a current, active Oregon medical license as an MD, DO, or DPM. Under ORS 677.495 and OAR 847-050, the physician who signs a PA collaboration agreement must have a license in good standing. A physician whose license is restricted or under a disciplinary order may not serve as a PA collaborating physician during the period of restriction.
No Specialty Alignment Requirement
Oregon does not impose a formal specialty alignment requirement on the collaborating physician. The collaboration agreement must describe the PA’s process for collaboration with physicians as clinically indicated, and the physician or employer determines the appropriate degree of collaboration based on the PA’s education, experience, and the community standards of care. The absence of a formal specialty mandate does not eliminate the expectation that the physician’s background is clinically relevant to the PA’s practice area.
No Geographic Proximity Requirement
Oregon does not impose a geographic proximity requirement on collaborating physicians. A physician in Portland may sign a collaboration agreement with a PA practicing in Eugene without any distance restriction. The physician must be accessible for consultation and collaboration as the PA’s practice requires, but physical proximity is not mandated.
No Ratio Limit
Oregon does not impose a statutory cap on the number of PAs a physician may have collaboration agreements with simultaneously.
Chart Review Obligations for Oregon Physician Collaborators
Under ORS 677.495(5) and OAR 847-050-0037(6), a physician providing oversight under a collaboration agreement must provide regular and routine oversight and chart review. Oregon does not specify a minimum percentage of charts to be reviewed or a mandatory review frequency beyond the requirement that the review be regular and routine.
The expectation is that chart review occurs as part of a functioning collaborative practice, not that it satisfies a numerical quota. A physician who conducts no chart review at all is not meeting the oversight standard. A physician who reviews charts regularly and adjusts the frequency based on the PA’s experience, the practice context, and the community standard of care is fulfilling the obligation.
During the performance assessment plan period for PAs with fewer than 2,000 hours of experience, the regularity of collaboration and oversight is heightened by the plan’s requirement for consistent and quality collaboration on a regular basis with the named physician.
The Title Change: Physician Assistant Becomes Physician Associate
HB 4010 (2024), enacted and effective June 6, 2024, changed the title of physician assistant to physician associate throughout Oregon statute. This change is reflected in all Oregon Medical Board communications, forms, and publications effective that date.
What This Means for Collaboration Agreements
Collaboration agreements signed before June 6, 2024 that use the term physician assistant remain valid and do not need to be reissued solely because of the title change. New agreements executed after that date should use the current statutory term physician associate. The Oregon Medical Board clarified this in its guidance on HB 4010.
Prescriptive Authority in Oregon
APRN Prescribing
Oregon APRNs with prescriptive authority may independently prescribe any drug within their scope of practice, including Schedule II through V controlled substances with a valid DEA registration. No physician agreement, protocol, or authorization is required for any aspect of Oregon APRN prescribing.
PA Prescribing
Oregon PAs may prescribe medications, including controlled substances, within the scope defined by their collaboration agreement. Under ORS 677.510, a PA practicing under a collaboration agreement may issue prescriptions consistent with the collaboration agreement and applicable state and federal law.
Pain Management Education
Under ORS 677.510, a PA who prescribes controlled substances for the treatment of pain must complete pain management continuing education as required by the Oregon Medical Board. Physicians should be aware of this obligation when entering collaboration agreements with PAs who treat pain patients.
Common Compliance Considerations for Oregon Collaborating Physicians
Most Oregon PA collaboration compliance issues involve documentation gaps, inadequate performance assessment plan content, and failure to update agreements when circumstances change.
- Agreement not in place before PA commences practice. Every Oregon PA must have a written collaboration agreement before practicing medicine. A PA who begins seeing patients before the agreement is signed is operating without the required legal structure.
- Performance assessment plan not included for sub-2,000-hour PAs. If a PA has fewer than 2,000 post-graduate clinical hours, the collaboration agreement must contain the performance assessment plan. A standard collaboration agreement that omits this plan for a newer PA does not satisfy OAR 847-050-0082(2)(d).
- 2,000-hour threshold not tracked. The PA, physician, or employer is responsible for tracking hours toward the 2,000-hour threshold. When the threshold is reached, the performance assessment plan must be removed from the agreement by written amendment. Agreements that still require a performance assessment plan for a PA who has exceeded 2,000 hours are outdated.
- Multiple practice locations not addressed. If the PA practices at more than one location, the collaboration agreement must address any differences in the collaboration process based on practice location. A single-site agreement for a multi-site PA may not be adequate.
- No genuine chart review occurring. The physician must provide regular and routine chart review under ORS 677.495(5). A physician who never reviews any charts under the arrangement is not meeting the oversight standard regardless of what the agreement says.

Clinics Also Need to Understand Oregon Collaboration Requirements
While this guide primarily covers the physician collaboration framework in Oregon, these regulations directly affect PA-operated clinics and healthcare practices that depend on physician collaboration to operate. NP-operated clinics in Oregon do not require physician collaboration under state law. PA-operated clinics or clinics that employ PAs must have compliant collaboration agreements in place for every PA, with performance assessment plans included for any PA with fewer than 2,000 post-graduate clinical hours.
Need Help Finding an Oregon Collaborating Physician?
For clinics with PA providers, the next challenge is finding a qualified physician or identifying an employer structure that satisfies the collaboration agreement requirement, with particular attention to the performance assessment plan obligations for newer PAs. Whether you are launching a new PA-operated clinic, employing your first PA, managing the 2,000-hour hour-tracking obligation for a newer PA, or updating an existing agreement after a PA’s practice location changes, having the right physician relationship in place from the start matters.
If your clinic is actively looking for an Oregon collaborating physician, our team can match you with a qualified physician, often within 24 to 48 hours. We work with clinics across Oregon to simplify the physician matching process while supporting collaboration agreement drafting, performance assessment plan documentation, and long-term collaboration needs.
Final Thoughts
Oregon collaborating physician requirements reflect a state that has fully modernized its approach to both APRN and PA practice. NPs operate with full independence. PAs operate under a collaborative framework that recognizes the physician’s role as a consultation and oversight partner rather than a supervisor, with enhanced structured collaboration required during the PA’s first 2,000 hours of clinical experience.
For physicians entering the Oregon market, the most important steps are confirming that the collaboration agreement contains all required elements including the performance assessment plan for newer PAs, tracking hours toward the 2,000-hour threshold, conducting regular and routine chart review as the oversight standard requires, and updating the agreement in writing whenever circumstances change.

Frequently Asked Questions
Does an Oregon NP need a collaborating physician?
No. Oregon is a full-practice-authority state for APRNs. Nurse practitioners in Oregon may independently diagnose, treat, and prescribe, including controlled substances, without any physician collaboration agreement, protocol, or oversight under ORS Chapter 678. Collaboration with other providers is a professional clinical standard, not a regulatory prerequisite tied to licensure or prescribing authority.
Do Oregon PAs need a collaborating physician?
Yes. Under ORS 677.510 and OAR 847-050-0082, every Oregon PA must have a written collaboration agreement in place before practicing medicine. The agreement must be signed by a physician (MD, DO, or DPM) or an employer as defined in OAR 847-050-0010(4). Oregon PAs transitioned to this collaborative practice model by December 31, 2023.
What changed when Oregon renamed physician assistants to physician associates?
HB 4010 (2024), effective June 6, 2024, changed the title from physician assistant to physician associate throughout Oregon statute. Existing collaboration agreements using the old title remain valid and do not need to be reissued solely because of the title change. New agreements should use the current term physician associate.
What is the Oregon 2,000-hour performance assessment plan?
For PAs with fewer than 2,000 hours of post-graduate clinical experience, the collaboration agreement must include a performance assessment plan that identifies a specific named physician for regular collaboration and describes how and how often that collaboration will occur. The PA, physician, or employer tracks the hours toward the 2,000-hour threshold. When the threshold is reached, the plan must be removed from the agreement by written amendment.
Does an Oregon physician need to file a PA collaboration agreement with the Oregon Medical Board?
No. Collaboration agreements are not filed with the OMB before the PA begins practice. The agreement must be kept on file at the PA’s primary location of practice and produced to the OMB upon request. The physician or employer must provide a copy of the agreement to the PA.
Can an Oregon employer sign the PA collaboration agreement instead of a physician?
Yes. Under OAR 847-050-0082 and ORS 677.495, the collaboration agreement may be signed by a physician or an employer as defined in OAR 847-050-0010(4). An employer in this context includes a health care entity such as a hospital, medical group, or health system. In smaller practice settings without an institutional employer structure, an individual physician signs the agreement.
