PA Scope of Practice by State: What Employers Need to Know in 2026

By Blake Moser · Published March 17, 2026

Why Understanding PA Scope of Practice Is Critical for Employers

Physician assistant scope of practice is not uniform across the United States — and the differences matter enormously for healthcare employers. Where a PA can practice independently, what medications they can prescribe, how much physician oversight is legally required, and whether they can bill independently for telehealth services all depend on the state where they're licensed. Employers who understand these rules gain a decisive competitive advantage in PA recruiting: they can write accurate job descriptions, structure compliant collaborative agreements, offer realistic scope of practice in their offers, and attract candidates whose career goals align with the practice environment.

The employer who can tell a PA candidate "in this state, you'll have full prescriptive authority, no required on-site supervision, and the ability to see patients independently in our urgent care locations" will outcompete the employer who says "we'll figure out the supervision agreement after you start." This guide gives employers the working knowledge they need to recruit, hire, and retain PAs compliantly and competitively across all 50 states.

Section 1: PA Scope of Practice — The Foundations

What Scope of Practice Means for Physician Assistants

Scope of practice defines the procedures, actions, and services a PA is legally authorized to perform within their state of licensure. For physician assistants, scope is governed by:

State PA Practice Acts — The primary legislation defining what PAs can and cannot do within a state
State Medical Board rules and regulations — Administrative rules that interpret and implement the Practice Act
Collaborative or supervisory practice agreements — Required in most states, detailing the specific scope the PA is authorized to perform under their supervising or collaborating physician
Facility or employer policies — Even where state law is permissive, individual health systems and hospitals can impose additional restrictions through credentialing and privileging processes

The American Academy of Physician Associates (AAPA) maintains a state-by-state legislative tracker that employers should consult when evaluating multi-state recruiting strategies.

The Role of the Supervising Physician and Collaborative Agreements

In the majority of U.S. states, PA practice requires a formal relationship with a physician — traditionally called a "supervising physician," though many states have moved to "collaborating physician" language to better reflect modern team-based care. This relationship typically involves:

A written practice agreement or protocol document specifying the PA's authorized scope
A designated physician who is responsible for oversight (which may be general rather than on-site supervision in many states)
Chart review requirements (frequency varies by state — some require 10% monthly chart review, others require review only on request)
Availability requirements (the supervising/collaborating physician must generally be reachable by phone during the PA's clinical hours, even if not on-site)

For employers, establishing a compliant supervisory or collaborative agreement before the PA's first day is not optional — it is a prerequisite for the PA to be legally authorized to practice. Gaps in this documentation expose employers to licensing board complaints, malpractice coverage complications, and potential payor audits.

How PA Scope of Practice Differs from NP Scope of Practice

The most important structural distinction is this: nurse practitioners in 27+ states have full practice authority (FPA) and can evaluate, diagnose, and treat patients without any physician oversight. Physician assistants do not have an equivalent full independence pathway in most states. The closest equivalent is the Optimal Team Practice (OTP) framework — a policy position advanced by the AAPA that advocates for PA practice without mandatory supervision requirements. A handful of states have enacted OTP-aligned legislation, but even in those states, PAs typically still practice collaboratively with physicians by clinical preference.

Section 2: States with the Most Expansive PA Scope of Practice

Optimal Team Practice (OTP) States

The AAPA's Optimal Team Practice initiative advocates for state laws that allow PAs to practice without mandatory written supervision agreements, instead relying on team-based practice norms. As of 2026, the following states have enacted legislation aligned with OTP principles, removing mandatory supervisory agreement requirements for PAs:

Arizona — Removed mandatory supervision agreement requirement; PAs may practice independently in most settings
North Dakota — Enacted OTP legislation; collaborative practice without written agreement required
Wyoming — Legislation passed removing formal supervision agreement requirements
Kentucky — Updated PA Practice Act to remove supervisory agreement mandate
Michigan — Modernized PA practice law with expanded autonomy provisions

Additional states have introduced OTP legislation or are actively in the legislative process as of 2026. Employers recruiting in OTP states should verify current law with the relevant state medical or PA licensing board, as laws continue to evolve.

How OTP Impacts Hiring: Advantages for Employers in Permissive States

OTP and broadly permissive PA practice states offer concrete recruiting and operational advantages:

Faster operational deployment: No supervisory agreement negotiation means PAs can be credentialed and begin seeing patients faster after hire
Expanded PA candidate interest: Experienced PAs who have practiced with broad autonomy actively seek positions in states where that autonomy is preserved
Multi-site flexibility: In states with no on-site supervision requirement, PAs can rotate across multiple clinic locations without a supervising physician being physically present — a significant operational advantage for multi-location practices and telehealth programs
Telehealth expansion: OTP states generally allow PAs to initiate and conduct telehealth encounters with the same scope as in-person practice, without requiring synchronous physician co-presence

Section 3: States with the Most Restrictive PA Scope of Practice

States Requiring Direct Physician Supervision

Several states continue to require active, on-site physician supervision for PA practice, particularly in hospital and procedural settings. This means a licensed physician must be physically present in the facility (not just available by phone) during the PA's clinical activities. Employers in these states face:

Higher physician staffing costs to maintain supervision ratios
Constraints on PA deployment to satellite clinics or telehealth settings
Reduced candidate attraction — PAs who have practiced in permissive states often resist moving to states with direct supervision requirements

States with the most restrictive traditional supervision frameworks (as of 2026) include portions of the Southeast and certain Midwest states. Employers should verify current requirements with state medical boards directly, as laws change through legislative sessions annually.

States with Strict Prescriptive Authority Limitations

While PAs have prescriptive authority in all 50 states for most medications, the authority to prescribe Schedule II controlled substances — which includes opioids, stimulants, and many psychiatric medications — varies by state. In some states, prescribing Schedule II substances requires:

A specific prescriptive authority agreement (separate from the supervision agreement)
Physician countersignature on Schedule II prescriptions within a defined timeframe
Limits on the number of prescriptions or days' supply a PA can authorize per patient

For specialty practices in pain management, psychiatry, addiction medicine, and oncology — where Schedule II prescribing is central to clinical practice — these restrictions meaningfully shape the PA's scope and the employer's operational capabilities.

Impact on Recruiting: How Restrictions Affect Candidate Interest

PA candidates researching employers routinely evaluate state scope of practice laws as part of their job search process. MedicalRecruiting.com's candidate survey data consistently shows that experienced PAs (5+ years in practice) rate scope of practice laws among the top three factors influencing geographic job preferences — after compensation and practice setting. Restrictive states face measurable disadvantages in PA candidate attraction, which employers can partially offset through:

Higher base compensation ($8,000–$15,000 annual premium to attract candidates from permissive states)
Clear communication about the collaborative relationship structure — candidates who fear micromanagement need specific reassurance about how supervision works in practice
Sponsoring state-level advocacy through the state PA association, which signals investment in the profession

Section 4: Key Scope of Practice Factors for Employers

Prescriptive Authority — Schedule II Through V

All 50 states allow PAs to prescribe controlled substances in Schedules III–V. Schedule II prescriptive authority (the most restrictive category, including drugs like oxycodone, amphetamine, and fentanyl) is permitted in most states but subject to the additional requirements described above. The NCCPA and AAPA both maintain regulatory resources tracking controlled substance prescribing authority by state — these should be reviewed when onboarding a PA to a specialty where controlled substance prescribing is clinically essential.

Surgical First Assist Privileges

Surgical PA scope of practice involves a dual-layer authorization: the PA must be licensed to perform surgical first assist procedures under state PA practice law, AND the hospital or surgical facility must grant individual surgical privileges through their credentialing process. Even in states where the PA practice act broadly authorizes surgical first assist, a hospital's medical staff bylaws can impose stricter requirements. Employers hiring surgical PAs should coordinate with their credentialing department early in the recruiting process to understand privilege requirements — this directly affects how quickly a newly hired surgical PA can begin productive OR work. For more detail, see our guide: PA Recruiting for Surgical Practices.

Telehealth and Telemedicine Scope Variations

The pandemic-era expansion of telehealth created a patchwork of PA telemedicine regulations that employers operating multi-state or virtual-first practices must navigate carefully. Key considerations:

State of care vs. state of licensure: Most states require a PA to hold an active license in the state where the patient is physically located at the time of the telehealth encounter — not just where the PA is licensed
Supervisory presence for telehealth: In restrictive states, the supervising physician may need to be available synchronously during telehealth encounters — a logistical complication for asynchronous telehealth models
Compact licensure: Unlike nursing (which has the NLC compact), PAs do not yet have a national multistate compact, meaning each additional state license requires a separate application, fee, and processing time

For telehealth-forward employers, hiring PAs with existing licenses in multiple states — or budgeting for multi-state licensing support — is a practical necessity.

Practice Agreement Requirements vs. State License Independence

In most states, the practice agreement is a separate, employer-level document — distinct from the PA's state license. This means the practice agreement can be modified, updated, or renewed without affecting the PA's underlying licensure. Best-practice employer protocol:

Establish the practice agreement before the PA's first clinical day
Review and update the agreement annually or whenever the PA's scope expands to new procedures or settings
Maintain copies in both the PA's personnel file and the supervising physician's file
Confirm that the supervising physician named in the agreement maintains an active, unrestricted license — a supervising physician who loses their license invalidates the PA's authority to practice under that agreement

Section 5: How Scope of Practice Affects PA Recruiting

Candidates Prefer States with Broader Scope

The data is consistent: states that have modernized their PA practice laws see higher PA candidate interest, shorter time-to-fill for PA positions, and lower turnover among placed PAs. Experienced PAs who have built clinical confidence and independence over 5–10 years are unlikely to accept positions in states that will require them to operate under more restrictive supervision than their prior role. Understanding where your state sits on the scope spectrum helps employers calibrate expectations before the search begins.

Compensation Adjustments in Restrictive vs. Permissive States

State scope of practice laws create measurable compensation differentials in the PA market. National compensation benchmarks from the AAPA show that restrictive states — where PA practice requires more physician oversight and PA billing flexibility is reduced — tend to pay 5–12% less than permissive states for comparable PA roles. Employers in restrictive states who want to attract high-caliber PA candidates should benchmark compensation against national (not just regional) data and budget a scope-of-practice premium into their offer structure when recruiting from out of state.

Frequently Asked Questions: PA Scope of Practice for Employers

Do physician assistants have full practice authority like nurse practitioners?

No — physician assistants do not have a direct equivalent to the nurse practitioner Full Practice Authority (FPA) model. In 27+ states, NPs can practice, diagnose, and treat patients entirely independently. PAs, by contrast, practice under some form of physician collaborative or supervisory relationship in nearly all states. The AAPA's Optimal Team Practice (OTP) initiative advocates for laws that eliminate mandatory written supervisory agreements for PAs, and a small number of states have enacted OTP-aligned legislation — but even in those states, PAs typically continue to practice in collaborative team environments with physicians. The structural difference reflects the distinct training and certification pathways of the two professions, not a difference in clinical competency.

What is Optimal Team Practice (OTP) and which states have enacted it?

Optimal Team Practice is the AAPA's policy framework advocating for PA practice laws that eliminate mandatory supervisory agreement requirements, allow PAs to be compensated directly by health systems, and permit PAs to be employed without a physician acting as a legal intermediary. As of 2026, states that have enacted OTP-aligned legislation include Arizona, North Dakota, Wyoming, Kentucky, and Michigan, with additional states actively pursuing similar reforms. OTP does not mean PAs practice without physicians — it means the formal written agreement requirement is removed, allowing team-based practice to be governed by clinical norms rather than legal mandates. Employers in OTP states have greater flexibility in deploying PAs across settings and hiring them directly without physician co-employment structures.

Can a PA prescribe controlled substances in all 50 states?

PAs have prescriptive authority for controlled substances in all 50 states, but Schedule II prescribing authority varies. In most states, PAs can prescribe Schedule II controlled substances (including opioids, stimulants, and certain psychiatric medications) with a DEA registration. However, some states impose additional requirements — such as a specific prescriptive authority agreement separate from the supervision agreement, physician countersignature requirements within a defined period, or limitations on days' supply or quantity. For specialty practices in pain management, psychiatry, addiction medicine, or oncology where Schedule II prescribing is essential, employers should confirm the state's specific requirements with the relevant licensing board before structuring the PA's practice agreement.

Does a PA need to be licensed in each state where they see telehealth patients?

In most cases, yes. The prevailing standard for telehealth regulation is that the PA must hold an active license in the state where the patient is physically located at the time of the encounter — not just where the PA's home state license was issued. Unlike nursing, which has the Nurse Licensure Compact allowing multi-state practice under a single license, PAs do not yet have an equivalent national compact as of 2026. Employers operating telehealth programs that serve patients across multiple states should budget for multi-state PA licensing support — application fees, processing times (which can run 30–90 days per state), and ongoing license renewal costs all add up. Some employers offer licensing support as part of their PA benefits package, which is a meaningful differentiator in recruiting telehealth-oriented PA candidates.

How do PA scope of practice laws affect PA recruiting and compensation?

PA scope of practice laws have a measurable and direct impact on both candidate attraction and compensation benchmarks. Experienced PAs consistently rank scope of practice among the top three factors influencing geographic job preferences. States with restrictive supervision requirements see longer PA search timelines, higher candidate turnover rates, and compensation premiums needed to attract candidates from permissive states. AAPA national salary data shows that permissive-scope states tend to pay 5–12% more than restrictive states for comparable PA roles, partly reflecting the premium candidates command for broader practice autonomy. Employers in restrictive states should benchmark compensation nationally rather than regionally, communicate clearly about how supervision works in practice (candidates fear micromanagement, not collaboration), and budget for the recruiting premium that scope restrictions create.
