PA State Regulations
PA State Regulations: OTP Framework, Supervision Requirements & Prescriptive Authority
The Optimal Team Practice model has reshaped PA practice authority in 29 states and D.C. Understanding which framework governs your state determines what services you can offer, how you structure your practice agreements, and what you can legally communicate on your website.

1. The OTP Framework: What It Changes and What It Does Not
The AAPA's Optimal Team Practice model is the most significant shift in PA regulatory history. It replaces the physician-supervision requirement with a collaborative practice model that treats PAs as full members of the healthcare team rather than supervised extenders.
What OTP removes:
- • Mandatory written supervision agreements with a designated supervising physician
- • Requirements for physician co-signatures on documentation
- • Defined percentages of chart review by a supervising physician
- • Mandatory on-site physician presence during PA patient care
- • Physician responsibility for PA prescribing decisions
What OTP does not change:
- • PA scope of practice remains defined by education, training, and experience
- • PAs still cannot practice without a valid PA license
- • Controlled substance prescribing still requires DEA registration
- • Hospital credentialing may still require physician relationship documentation
- • Medicare billing under the PA's own NPI still reimburses at 85% physician rate
The practical effect in OTP states: PAs can practice in settings without an employed supervising physician, work in rural and underserved areas with less administrative overhead, and structure their own practices with physician collaboration rather than supervision.
2. OTP-Adopted States: Current Map (2026)
As of May 2026, 29 states and the District of Columbia have adopted OTP legislation or regulations that remove mandatory physician supervision requirements. This number has grown from 18 states in 2022, reflecting accelerating legislative momentum.
OTP-adopted jurisdictions (2026):
Arizona, Colorado, Connecticut, Delaware, District of Columbia, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Mexico, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Dakota, Utah, Vermont, Washington, Wyoming

OTP adoption does not follow a simple geographic pattern. Rural-heavy states with provider shortage areas have driven much of the adoption, but several coastal states with historically restrictive PA practice laws remain in the traditional supervision category.
Multi-state practice:If you hold licenses in multiple states, you operate under each state's individual framework. A PA licensed in Pennsylvania (OTP) and New York (traditional supervision) must comply with New York requirements when seeing New York patients — even via telehealth.
3. Traditional Supervision States: Requirements and Administrative Burden
In the 21 states that have not yet adopted OTP, PAs must maintain a formal supervision relationship with a licensed physician. The specific requirements vary significantly by state, but all share a common administrative overhead that affects practice structure.
- Written supervision agreements: Most traditional supervision states require a formal, signed supervision agreement that defines scope, availability, and review responsibilities. These must typically be filed with the state medical or PA licensing board.
- Physician availability requirements:States typically require the supervising physician to be reachable within defined timeframes (often "immediately" or within 1–2 hours). This limits PAs practicing in settings where physicians are not readily available.
- Chart review percentages: Many states require the supervising physician to review a defined percentage of PA-generated charts — commonly 10–20% for established PAs. Some states require 100% review for new PAs in their first 6–12 months.
- Prescribing limitations: Traditional supervision states may restrict PA prescribing to drug categories specifically authorized in the supervision agreement or state formulary.
Finding and maintaining a supervising physician is itself a significant challenge for PAs seeking independent-adjacent practice in these states. Many PAs pay formal supervision fees ($500–$3,000/month) to physicians who provide this relationship without clinical involvement.
Practice note:If you are in a traditional supervision state, your website should accurately reflect your supervision arrangement. Describing yourself as "independently practicing" when you require a supervision agreement creates both a credentialing risk and a potential board complaint exposure.
5. Supervision and Collaboration Agreements: What to Include
Whether your state requires a supervision agreement or a collaborative practice agreement, the document serves a practical purpose beyond regulatory compliance: it defines the scope, liability, and communication expectations between you and your collaborating physician.
Core agreement elements:
- • Scope of practice: specific services, patient populations, procedures authorized
- • Geographic scope: locations where the agreement applies
- • Availability and consultation protocols: how and when to contact the collaborating physician
- • Chart review obligations: percentage, frequency, and documentation method
- • Prescriptive authority: drug classes, schedule levels, and any formulary restrictions
- • Agreement duration, renewal, and termination provisions
- • Compensation or fee structure (if physician is being compensated)
Paid supervision relationships:It is legal and common for PAs to pay physicians for supervisory or collaborative relationships. Document the agreement carefully and ensure the physician's malpractice coverage addresses their supervisory role. An attorney with healthcare licensure experience should review any supervision agreement before signing.
Store signed agreements in a secure, accessible location. State boards can request them during audits, licensing renewals, or complaint investigations. Maintain copies for at least 7 years after the agreement ends.
6. How Regulations Affect What You Can Say on Your Website
Your state's regulatory framework directly shapes the language you use on your practice website. Overstating your authority — even inadvertently — creates board complaint exposure.
- OTP states:You may accurately describe a collaborative or team-based practice model. Avoid language like "independent practice" unless your state has explicitly removed all physician relationship requirements — most OTP states still require a collaboration framework, not full independence.
- Traditional supervision states:Never describe yourself as practicing independently. Use accurate language: "practicing in collaboration with [physician name/group]," "PA-led practice with physician oversight," or "physician-supervised care."
- Title use:Following the AAPA's 2021 name change, "physician associate" is now the preferred full title, though "physician assistant" remains on most state licenses. Use the title as it appears on your state license in all formal materials and on your website credential display.
- Prescribing disclosures: If you offer medication management services, confirm your state allows you to advertise prescribing authority without additional disclaimers. Some states regulate how APP prescribing is described in marketing materials.
A compliant website is also a credibility asset. Patients and referral sources who understand PA practice will recognize accurate regulatory language as a sign of professionalism.
