Arizona collaborating physician requirements reflect a full-practice-authority state for nurse practitioners with a modernized, two-track physician collaboration structure for physician assistants. Arizona has granted full practice authority to NPs since 2001, one of the first states in the country to do so. No physician collaboration agreement, protocol, or oversight is required for Arizona NP practice or prescribing under A.R.S. § 32-1601 et seq.
For physicians seeking collaboration income in Arizona, the active statutory framework centers entirely on physician assistants. Arizona’s enactment of HB 2043, effective January 1, 2024, created two distinct PA practice tracks based on AZPA-certified clinical experience. PAs with fewer than 8,000 certified hours must operate under a written supervision agreement with a supervising physician. PAs with 8,000 or more certified hours may practice collaboratively without a supervision agreement, though written individualized policies must still be developed with a collaborating physician or entity. This guide covers every requirement physicians need to understand in 2026.
Arizona Collaborating Physician Overview: Where Arizona Stands
Arizona is a full-practice-authority state for advanced practice registered nurses and has been since 2001. The Arizona State Board of Nursing (AZBN) governs APRN practice under A.R.S. § 32-1601 et seq. and Arizona Administrative Code Title 4, Chapter 19.
Governing Bodies
Two regulatory bodies govern provider practice in Arizona:
- Arizona State Board of Nursing (AZBN): Governs APRN licensure, scope of practice, prescriptive authority, and disciplinary matters. NPs in Arizona practice without any physician oversight requirement under AZBN authority.
- Arizona Regulatory Board of Physician Assistants (AZPA): Governs PA licensure, supervision agreement requirements, collaborative PA certification, and disciplinary matters under A.R.S. § 32-2501 et seq. The Arizona Medical Board (AZMD) coordinates with the AZPA on physician supervisory obligations.
Arizona’s Position on NP Collaboration
Arizona law does not require NPs to enter into any collaborative or supervisory arrangement with a physician as a condition of practice or prescribing. This has been Arizona’s position since 2001. Some employers or hospital systems may impose internal collaboration requirements, but these are institutional policies, not state law requirements.
NP Practice Authority in Arizona: Full Independence Since 2001
Arizona APRNs licensed under A.R.S. § 32-1601 et seq. may independently assess, diagnose, treat, and prescribe without any physician involvement at any stage of their career. Arizona was among the first states nationally to adopt this model and remains a leading example of how full practice authority functions in a large, geographically diverse state.
What Arizona APRNs May Do Without a Physician
A licensed Arizona APRN may independently:
- Conduct comprehensive health assessments and obtain medical histories
- Diagnose using clinical judgment and diagnostic tests
- Order and interpret laboratory and imaging studies
- Develop and implement treatment plans
- Prescribe legend drugs and pharmacologic treatments
- Prescribe Schedule II through V controlled substances with a valid DEA registration and CSPMP compliance
- Operate independent practices across any practice setting
The CSPMP Requirement
Under A.R.S. § 36-2606, APRNs prescribing controlled substances in Arizona must comply with the Controlled Substances Prescription Monitoring Program (CSPMP). This includes checking the CSPMP as required before prescribing opioids and certain other controlled substances. This is a prescribing compliance obligation, not a physician collaboration requirement.
Medspa and Procedural Settings
The Arizona State Board of Nursing issued a 2025 Advisory Opinion confirming that NPs performing Level II or III procedures in medspa or procedural settings must have a written provider order and a good-faith examination on file, which may be issued by an MD, DO, or NP. Physicians are not exclusively required for this function. The AZBN advisory opinion applies specifically to procedure-level protocols in those settings and does not create a physician collaboration requirement for NP prescribing or general clinical practice.
Where Physician Collaboration Applies: The PA Two-Track Framework
Active statutory physician collaboration requirements in Arizona apply exclusively to physician assistants under A.R.S. § 32-2531 as amended by HB 2043. As of January 1, 2024, every Arizona PA falls into one of two practice tracks:
- Track 1: PAs with fewer than 8,000 AZPA-certified clinical hours who must operate under a written supervision agreement with a supervising physician
- Track 2: PAs who have completed 8,000 or more AZPA-certified clinical hours and received board certification for collaborative practice, who may practice without a supervision agreement but must maintain written individualized policies with a collaborating physician or entity
The track that applies to a specific PA is determined by the AZPA’s certification of the PA’s completed clinical hours. The physician’s role, obligations, and legal liability differ significantly between the two tracks.
Track 1: The Supervision Agreement for PAs Under 8,000 Hours
Under A.R.S. § 32-2531, a physician assistant who has fewer than 8,000 hours of clinical practice certified by the AZPA must work in accordance with a supervision agreement that describes the PA’s scope of practice. A PA may not perform any health care tasks until a supervision agreement has been completed and signed.
No Physical Presence Required
Under A.R.S. § 32-2531, supervision may occur through electronic means and does not require the physical presence of the supervising physician at the time or place the physician assistant provides medical services. A physician in Scottsdale may supervise a PA practicing in Flagstaff without any proximity restriction.
Where the Agreement Must Be Kept
The supervision agreement must be kept on file at the main location of the physician assistant’s practice and made available to the AZPA board or the board’s representative on request. The agreement is not filed with the AZPA before the PA begins practice, but must be immediately available when requested.
Annual Update Requirement
Under AZPA guidance and A.R.S. § 32-2531(H)(4), the supervision agreement must be signed by the supervising physician and the physician assistant and updated annually. An agreement that has passed the one-year mark without a current signature from both parties is not current.
When the Track 1 Requirement Ends
On receipt of AZPA certification of the PA’s completion of at least 8,000 hours of clinical practice, the PA is no longer subject to the supervision agreement requirements of this subsection. The transition to Track 2 collaborative practice does not require the supervising physician’s action. It is triggered by AZPA board certification upon the PA’s application and documentation.
What the Arizona PA Supervision Agreement Must Contain
Under A.R.S. § 32-2531(H)(4) and AZPA board guidance, the supervision agreement must include at minimum:
1. Statement of Supervision and Legal Responsibility
The agreement must state that the supervising physician will exercise supervision over the physician assistant and that the physician retains professional and legal responsibility for the care rendered by the PA. This language is mandatory. A supervision agreement that does not contain this explicit statement of retained liability does not satisfy the statutory standard.
2. Scope of Practice Description
The agreement must describe the PA’s scope of practice. This description defines the health care tasks the PA is authorized to perform under the supervision arrangement. Health care tasks not described in the agreement are not within the PA’s authorized scope under the arrangement.
3. Signatures of Both Parties
The agreement must be signed by the supervising physician and the PA. An unsigned or one-party-only signed agreement is noncompliant.
4. Annual Update
The agreement must be updated annually. Each annual update requires a new signature from both parties with a current date.
Supervising Physician Duties Under ARS § 32-2531
Under A.R.S. § 32-2531(H), a supervising physician has specific statutory duties that apply during the Track 1 supervision relationship. These are not aspirational standards. They are enforceable legal obligations.
1. Meet AZPA Supervision Requirements
The supervising physician must comply with all requirements the AZPA establishes for physician supervision of PAs under the statute and board rules.
2. Accept Responsibility for Delegated Tasks
The supervising physician must accept responsibility for all tasks and duties delegated to the PA. This is the core liability obligation of the Track 1 supervision model. The physician’s professional and legal responsibility for the PA’s care is stated in the agreement and in the statute.
3. Notify AZPA and PA of Scope Exceedance
If the PA exceeds the scope of the delegated health care tasks described in the supervision agreement, the supervising physician must notify the AZPA and the PA in writing. This notification obligation is active and specific. A physician who is aware the PA is providing services outside the agreement’s scope and fails to notify the board is not meeting the statutory duty.
4. Maintain the Written Agreement
The supervising physician must maintain a written supervision agreement with the physician assistant. The AZPA confirms on its website that all supervising physicians must maintain a written delegation agreement with their assigned physician assistants.
Track 2: The Collaborative PA With 8,000 or More AZPA-Certified Hours
Under HB 2043 and A.R.S. § 32-2563, a PA who has completed at least 8,000 hours of clinical practice within the previous five years in Arizona or another jurisdiction and received AZPA certification for collaborative practice may practice without a supervision agreement.
The AZPA Certification Process
To become a certified collaborative PA, the PA must:
- Be licensed as a PA in Arizona and in good standing
- Have graduated from an accredited PA program
- Not currently be under investigation or subject to public or confidential disciplinary action
- Provide proof of completing at least 8,000 hours of clinical practice within the previous five years
The AZPA reviews the application and issues certification. Without AZPA certification, a PA with 8,000 hours of experience cannot operate as a collaborative PA. The hours must be documented and board-certified before the Track 2 framework applies.
The Physician’s Changed Role Under Track 2
For collaborative PAs, the physician or collaborating entity does not retain the same supervisory liability that applies in Track 2. Under A.R.S. § 32-2531, a PA who does not practice pursuant to a supervision agreement is legally responsible for the health care services they perform. The physician’s liability exposure under Track 2 is materially different from Track 1.
However, the physician or collaborating entity is still required to develop written individualized policies for each collaborative PA under their arrangement. These policies replace the supervision agreement as the core documentation framework.
What the Collaborative PA Individualized Policy Must Address
Under A.R.S. § 32-2531(B) and the AZPA’s collaborative practice FAQ, the collaborating physician or entity must develop written policies for each collaborative PA that are individualized to the PA’s education, experience, and practice setting. These policies must address:
1. Practice Setting and Specialty Comparability
The policies must reflect whether the PA’s new practice setting or specialty is substantially similar to the PA’s previous areas of practice. If the setting is substantially similar, the PA may begin practicing with the existing individualized policies in place.
2. Additional Training Requirements for New Settings
If the new practice setting or specialty is not substantially similar to the PA’s prior experience, the policies must describe the additional training, oversight, and education that will be provided to ensure the PA can safely practice in the new environment. This may include a temporary supervision agreement during the transition period.
3. Collaboration Structure
The policies must reflect how the collaborative PA will collaborate with, consult with, or refer to appropriate health care professionals as indicated by the patient’s condition, the community standards of care, and the PA’s education, experience, and competencies.
4. Documentation of Practice and Clinical Hours
The policies must document the PA’s prior practice history and how the 8,000-hour threshold was satisfied, to support the AZPA’s certification process.
Specialty Change and the New-Setting Transition Requirement
One of the most practically significant features of Arizona’s collaborative PA framework is the rule that applies when a certified collaborative PA moves into a practice setting or specialty that is not substantially similar to their prior experience.
When Additional Oversight Is Required
If a collaborative PA accepts a position in a clinical area with substantially different patient populations, procedures, or clinical demands than their prior 8,000-hour practice history, the collaborating physician or entity may determine that additional training, oversight, and education are warranted. The individualized policies must describe this additional support.
When a Temporary Supervision Agreement May Be Required
In cases where the new setting or specialty poses sufficient patient safety concerns, the collaborating physician may determine that a temporary supervision agreement is necessary during the transition period. Once the PA has demonstrated competency in the new setting, the supervision agreement may be terminated by written addendum to the individualized policies, and the PA may proceed under collaborative practice.
This specialty-change transition requirement prevents the 8,000-hour certification from functioning as a blanket authorization for PAs to practice without oversight in any clinical context regardless of their specific experience.
Physician Eligibility for Both PA Practice Tracks
A qualifying Arizona physician for Track 1 PA supervision or Track 2 PA collaboration must hold a current, active Arizona medical license issued by the Arizona Medical Board. The physician must be in good standing with no restrictions that would impair their ability to supervise or collaborate with a PA.
Scope Alignment
Under A.R.S. § 32-2531, the tasks and duties delegated to a PA in a Track 1 supervision arrangement must be within the scope of the supervising physician’s own medical practice. A physician cannot delegate clinical tasks to a PA that the physician is not themselves qualified to perform. For Track 2 collaborative PAs, the individualized policies must reflect the PA’s competencies and the clinical context, and the physician or entity developing those policies should have meaningful clinical familiarity with the PA’s practice area.
No Geographic Proximity Requirement
Arizona does not impose a geographic proximity requirement on supervising or collaborating physicians. Supervision and collaboration may occur through electronic means. A physician in Phoenix may serve as supervising physician for a PA practice in Tucson or any other Arizona location without any distance restriction.
No Ratio Limit
Arizona does not impose a statutory cap on the number of PAs a physician may supervise or collaborate with simultaneously.
Prescriptive Authority and Controlled Substances in Arizona
APRN Prescribing
Arizona APRNs with prescriptive authority may independently prescribe any drug within their scope, including Schedule II through V controlled substances, with a valid DEA registration and CSPMP compliance. No physician delegation or authorization is required for any APRN prescribing.
PA Prescribing
Under A.R.S. § 32-2531, Arizona PAs may prescribe medications including controlled substances within the scope of their supervision agreement or collaborative practice arrangement. PAs must hold a valid DEA registration for controlled substance prescribing. Under Track 1, prescribing authority is defined within the supervision agreement and delegated by the supervising physician. Under Track 2, prescribing authority flows from the PA’s collaborative practice certification and the individualized policies.
The CSPMP for PAs
Arizona PAs prescribing controlled substances must comply with the CSPMP under A.R.S. § 36-2606. This monitoring program requirement applies equally to PAs under both tracks.
The AZPA Board’s Investigation Protocol: Why the Written Agreement Is Critical
The AZPA’s stated policy on its public website makes the consequences of a missing supervision agreement explicit: the board will request the delegation agreement for every investigation opened on a PA. If the delegation agreement does not exist, an investigation will be opened on the supervising physician.
This policy means that any investigation of a Track 1 PA’s clinical conduct will automatically escalate to the supervising physician if the written agreement cannot be produced. The investigation is opened on the physician not as a secondary consequence, but as the direct, expected result of a missing document.
What This Means for Physicians
A supervising physician who signs an arrangement but does not maintain a current, executed, annually updated supervision agreement on file is creating a regulatory exposure that follows the PA into every future clinical complaint or investigation. The agreement is not an administrative afterthought. It is the legal foundation of the supervision relationship and the document the AZPA will specifically request when anything goes wrong.
Common Compliance Mistakes Arizona Collaborating Physicians Make
Most Arizona PA supervision and collaboration compliance problems involve documentation gaps, track misidentification, and failure to address the annual update requirement.
- Supervision agreement not updated annually. Under AZPA guidance and A.R.S. § 32-2531(H)(4), the supervision agreement must be updated and re-signed by both parties every year. An agreement executed more than one year ago without a current update is not compliant.
- Track misidentification: treating a collaborative PA as a supervised PA or vice versa. The physician’s obligations differ fundamentally between Track 1 and Track 2. A physician who develops a supervision agreement with a PA who is AZPA-certified as a collaborative practitioner is applying the wrong framework. A physician who skips the supervision agreement for a PA who has not yet received AZPA collaborative certification is not meeting the required Track 1 standard.
- Supervision agreement does not include the mandatory liability statement. The agreement must explicitly state that the physician retains professional and legal responsibility for the care rendered by the PA. An agreement that omits this language does not satisfy the statutory requirement.
- Delegating tasks outside the physician’s own scope. Under A.R.S. § 32-2531, delegated tasks must be within the supervising physician’s own practice scope. A physician who delegates clinical tasks they are not themselves qualified to perform creates a compliance problem in both the agreement and the clinical practice.
- No notification to AZPA when PA exceeds delegated scope. If a Track 1 PA performs services outside the supervision agreement’s authorized scope, the physician must notify the AZPA and the PA in writing. Physicians who become aware of scope exceedance without notifying the board are not meeting the statutory duty.
- Collaborative PA individualized policies not developed or not updated. For Track 2 collaborative PAs, the collaborating physician or entity must develop written individualized policies. These policies must reflect the PA’s specific education, experience, and practice setting. Generic policies that apply uniformly to all PAs do not satisfy the individualization requirement.

Clinics Also Need to Understand Arizona Collaboration Requirements
While this guide primarily covers the physician collaboration framework in Arizona, these regulations directly affect PA-operated clinics and healthcare practices that depend on physician collaboration for Track 1 supervision or Track 2 policy development. NP-operated clinics in Arizona do not require physician collaboration under state law. PA-operated clinics, or clinics that employ PAs, must have the correct framework in place for each PA’s track before the PA begins practice.
Need Help Finding an Arizona Collaborating Physician?
For clinics with Track 1 PAs, the next challenge is finding a qualified physician who is prepared to execute a compliant supervision agreement that includes the mandatory liability statement, update it annually, and fulfill the notification obligations if the PA exceeds the agreement’s scope. For clinics with Track 2 collaborative PAs, the challenge is finding a physician or entity willing to develop individualized written policies tailored to the PA’s specific education and practice setting. Whether you are launching a new PA-operated clinic, onboarding a new PA who has not yet reached 8,000 hours, or managing a collaborative PA who is transitioning into a new specialty area, having the right physician relationship in place from the start is essential.
If your clinic is actively looking for an Arizona collaborating physician, our team can match you with a qualified physician, often within 24 to 48 hours. We work with clinics across Arizona to simplify the physician matching process while supporting supervision agreement drafting, annual update tracking, individualized policy development, and long-term collaboration needs.
Final Thoughts
Arizona collaborating physician requirements reflect a state that has solved the NP collaboration question entirely through full practice authority while maintaining a structured, two-track physician collaboration framework for PAs. The Track 1 supervision agreement is a substantive legal instrument that places real liability on the supervising physician and will be the first document the AZPA requests in any investigation. The Track 2 collaborative framework reduces that liability but does not eliminate the physician’s role in developing individualized policies that reflect the PA’s specific experience.
For physicians entering the Arizona market, the most important steps are confirming which track applies to the specific PA, ensuring the supervision agreement includes all required elements including the annual update, understanding the scope delegation limits that apply to Track 1, and for Track 2, developing genuinely individualized policies that reflect the PA’s education and practice history.

Frequently Asked Questions
Does an Arizona NP need a collaborating physician?
No. Arizona has been a full-practice-authority state for NPs since 2001 under A.R.S. § 32-1601 et seq. Arizona NPs may independently diagnose, treat, and prescribe, including controlled substances, without any physician collaboration agreement, supervision, or protocol under state law. Some employers or hospitals may have internal policies requiring physician involvement, but these are institutional rather than statutory requirements.
Do Arizona PAs need a collaborating physician?
Yes. Arizona PAs fall into two tracks under HB 2043, effective January 1, 2024. Track 1 PAs with fewer than 8,000 AZPA-certified clinical hours must have a written supervision agreement with a supervising physician before performing any health care tasks. Track 2 PAs with 8,000 or more AZPA-certified hours and board certification for collaborative practice do not need a supervision agreement but must have individualized written policies developed with a collaborating physician or entity.
What is the AZPA’s policy on missing supervision agreements?
The AZPA has explicitly stated on its public website that it will request the delegation agreement for every investigation opened on a PA. If the agreement does not exist, the board will open an investigation on the supervising physician. This policy makes the existence and currency of the written supervision agreement a direct regulatory risk factor for physicians.
How often does an Arizona PA supervision agreement need to be updated?
Under AZPA guidance and A.R.S. § 32-2531(H)(4), the supervision agreement must be signed by both the supervising physician and the PA and updated annually. Each annual update requires current signatures from both parties. An agreement that has passed the one-year mark without an update is not compliant.
What changes when a PA reaches 8,000 AZPA-certified clinical hours?
When a PA completes and the AZPA certifies 8,000 or more hours of clinical practice within the previous five years, the PA is no longer subject to the Track 1 supervision agreement requirement. The PA receives AZPA certification as a collaborative practitioner and may practice without a supervision agreement. The PA also assumes legal responsibility for their own clinical care, reducing the physician’s liability exposure compared to Track 1. The collaborating physician or entity must still develop individualized written policies for the collaborative PA.
Can an Arizona PA transition from Track 1 to Track 2 on their own?
No. The transition requires both completion of 8,000 documented clinical hours and AZPA board certification. The PA must apply to the AZPA with documentation of the hours, and the board must certify completion before the Track 2 collaborative framework applies. The supervising physician does not need to take any action to enable the transition, but should be aware that the supervision agreement requirement ends on AZPA certification.
