When a PA practice reaches out to a physician about an oversight arrangement, the first question is usually about rate and availability. The question that physicians should ask first — but rarely do — is: what model of arrangement are you describing? The word “collaboration” in the PA practice context covers arrangements that range from a physician sitting in the same office for a defined minimum of hours each week to a physician who reviews a monthly chart sample from their home office and responds to secure-message consultation requests. These are not variations on the same arrangement. They are fundamentally different commitments with different time requirements, different income profiles, different liability postures, and different state-law requirements.
This guide maps every distinct physician assistant collaboration arrangement model available to PA practices — what each one involves, what it pays, how much time it requires, which states allow or require each model, and which physician specialties are best suited for each type. Understanding the full model landscape is what allows a physician to evaluate any specific PA opportunity accurately before agreeing to its terms.
According to the Centers for Medicare and Medicaid Services (CMS) guidelines on physician supervision of physician assistants, the supervision framework for PAs extends to billing and reimbursement — meaning that how a physician oversight arrangement is structured affects not just the physician’s legal obligations but also how the PA’s services are billed and reimbursed in Medicare and Medicaid contexts. This federal layer exists on top of state-specific PA practice act requirements, and physicians entering any PA arrangement must understand both dimensions.
The Six Physician Assistant Collaboration Models: A Structural Overview
What are the different types of physician collaboration arrangements available to PA practices — and how do they differ in terms of physician obligation?
The PA collaboration arrangement models differ along four key dimensions: physician physical presence requirement, chart review structure, controlled substance scope, and administrative involvement. At the lightest end, a consultation-protocol arrangement (Model 4) requires the physician primarily to be available for consultation when triggered by specific clinical criteria — with no routine chart review requirement in some states. At the heaviest end, a traditional on-site supervisory arrangement (Model 3) requires the physician to be physically present at the PA practice location for a defined minimum of hours per week, with active chart co-signature and direct supervisory engagement. The model that most income-seeking physicians want — and that most independent PA practices use in the current telehealth and independent practice era — is the remote asynchronous oversight model (Model 1), where the physician reviews a defined percentage of charts remotely and on an asynchronous schedule, without ever needing to be physically present at the practice location. Understanding which model a specific PA practice is proposing before the rate conversation begins is the most important structuring question a physician can ask. A PA practice that needs Model 3 on-site supervision should not be compensating the physician at Model 1 asynchronous review rates — and a physician who accepts Model 3 obligations at Model 1 compensation is creating a significant mismatch between time investment and income. The supervising physician requirements in Tennessee, for example, define specific oversight obligations that determine which model is legally sufficient in that state — and physicians unfamiliar with state-specific requirements may agree to a model that does not satisfy state law, creating compliance risk for both parties.
Each Arrangement Model in Detail: What It Involves, What It Pays, Who It Fits
The remote asynchronous oversight model is the dominant arrangement for independent PA practices — particularly telehealth-adjacent PA practices, solo PA practices in outpatient settings, and PA practices in states that permit remote supervision. The physician reviews a defined percentage of patient charts remotely on a scheduled asynchronous basis (typically weekly), is available for consultation by secure message or phone during defined hours, and maintains documentation of each review session and consultation response.
This is the highest income-per-hour model for physician collaborators because the work is specifically bounded, asynchronous, and does not require any physical presence at the practice location. The physician performs chart review from any location, responds to consultation messages on their own schedule within a defined response window, and maintains oversight documentation in whatever system the practice uses (often the practice’s HIPAA-compliant EHR or a shared secure messaging platform).
Most states that require physician supervision or collaboration for PA practice accept remote oversight as legally sufficient for outpatient and telehealth PA settings, though the specific chart review percentage required varies by state statute. Physicians should verify that their specific state’s PA practice act explicitly permits remote supervision before entering this model.
Telehealth-only PA practices — PAs who see all patients through synchronous video or asynchronous telehealth encounters with no physical office — are the fastest-growing segment of the PA practice market. Physician oversight in this context is structurally remote by definition: the PA is remote, the patients are remote, and the physician’s oversight role is conducted through the same digital infrastructure the practice uses. Chart review is of telehealth encounter documentation, consultation happens through secure messaging, and attestation is performed within the telehealth platform’s compliance system.
The telehealth-only model typically has lower clinical complexity per encounter than in-person practices — telehealth PAs see patients who have self-selected for virtual care, which skews toward less acute, more manageable clinical presentations. This makes the per-chart review workload somewhat lighter than in-person equivalent practices, and the oversight is conducted entirely through digital tools with no location constraint whatsoever for the physician.
The traditional on-site supervisory model is the oldest and most structured form of PA oversight — in some states, it remains the legally required model for certain PA practice settings. The physician must be physically present at the PA’s practice location for a defined minimum of hours per week or per month, actively supervising clinical activities, co-signing specific categories of orders or prescriptions, and being directly accessible during the PA’s working hours. The model is required by a decreasing but still significant number of state PA practice acts, particularly in hospital-based, surgical, and emergency medicine settings.
For income-seeking physicians, Model 3 has the highest nominal monthly rate but the lowest effective hourly rate — because the physical presence requirement substantially increases time investment and creates location constraints that limit a physician’s ability to hold multiple simultaneous arrangements. A physician earning $2,500 per month for on-site supervision but investing 10 hours per week earns $62.50 per hour — compared to $175 to $250 per hour for the same monthly income from remote asynchronous oversight. Physicians considering on-site supervisory arrangements should evaluate the effective hourly rate carefully before accepting.
In states that permit a more collaborative (as opposed to supervisory) model for PA practice — where the agreement defines specific clinical circumstances that require physician consultation rather than mandating routine chart review of a defined percentage — a consultation-protocol arrangement becomes possible. In this model, the agreement defines the specific clinical triggers (complexity thresholds, diagnosis categories, medication types, abnormal findings) that require the PA to escalate to physician consultation. Outside of those triggers, the PA practices with greater independence.
This model requires the least average physician time per month — perhaps one to three hours per week on average — but can be episodically more demanding when consultation triggers are frequently met (a high-complexity PA practice will generate more consultations than a routine primary care telehealth practice). The lower time average supports a strong effective hourly rate despite the lower nominal monthly fee.
In some states and practice contexts, a PA’s primary need for physician oversight is limited to controlled substance prescribing delegation — the PA can practice independently or with minimal oversight in most clinical areas but requires a physician to authorize their CS prescribing authority. This creates a narrow-scope arrangement where the physician’s primary function is co-signing or delegating CS prescriptions within the scope defined by the state and the agreement, rather than conducting broad clinical oversight.
This model is most common in pain management PA practices, addiction medicine PA practices, and surgical PA practices where post-operative pain management is the primary CS context. The physician must hold an active DEA registration and be willing to include CS prescribing delegation in the agreement scope — which typically commands a CS premium of $200 to $600 per month above a baseline non-CS rate. Physicians without an active DEA registration or who are unwilling to include CS scope are not candidates for this specific model.
Some PA practices — particularly multi-PA group practices, specialty clinics, and PA practices with significant organizational complexity — want both a clinical oversight physician and a medical director for organizational leadership. When a single physician fills both roles, the combined monthly compensation reflects both the clinical oversight obligation and the administrative/policy obligations of the medical directorship. This is the highest nominal fee of any PA arrangement model.
However, the hybrid model also carries the medical director role’s additional obligations: policy development, protocol governance, possibly committee participation, and the non-compete or exclusivity provisions that are standard in medical director agreements. A physician who accepts a Model 6 hybrid arrangement may find that their non-compete agreement restricts their ability to hold additional PA or NP oversight arrangements in the same specialty or geographic market — which can eliminate the income scalability advantage that makes Models 1 and 2 so financially attractive.
All Six Models Compared: The Complete Reference Table
| Model | Monthly Rate Range | Weekly Time | Effective Hourly Rate | Oversight Complexity | Physical Presence | Scalability (Multi-Arrangement) | Best Physician Specialty Fit |
|---|---|---|---|---|---|---|---|
| Model 1: Remote Async Oversight | $1,200–$3,000 | 2–5 hrs/wk | $140–$260/hr | Low-Moderate | Not required | ✅ High — 2–4 arrangements common | FM, IM, any specialty comfortable with asynchronous review |
| Model 2: Telehealth-Only | $1,200–$2,800 | 2–4 hrs/wk | $150–$280/hr | Low-Moderate | Not required | ✅ High — can stack with other models | FM, IM, specialty with telehealth comfort |
| Model 3: On-Site Supervisory | $1,500–$3,500 | 4–12+ hrs/wk | $80–$140/hr | High | Required — defined minimum hrs | ⚠ Low — location constraint limits arrangements | Specialty match required; surgical, EM, procedural |
| Model 4: Consultation Protocol | $1,000–$2,200 | 1–3 hrs/wk avg | $140–$250/hr | Low | Not required | ✅ High — low time base allows stacking | Any specialty; requires state-specific validation |

“The on-site model pays the most per month. The remote asynchronous model earns the most per hour. The consultation-protocol model demands the least time. And the combined NP plus PA remote portfolio earns the most annually. Understanding these differences before evaluating any specific arrangement is what separates an informed decision from an expensive one.”
Which PA arrangement model pays physicians the most — and how should physicians choose between models when a PA practice gives them options?
The honest answer is that the highest-paying model depends on what you are measuring. The highest nominal monthly fee comes from the Model 6 medical director hybrid — which can reach $4,000 to $6,000 per month for a comprehensive dual-role arrangement. But the highest effective hourly rate typically comes from Model 1 remote asynchronous oversight — where a physician earning $2,500 per month for four hours per week of chart review is earning $156 per hour effective rate, compared to a medical director hybrid paying $3,500 per month for 14+ hours of combined chart review and administrative work, which works out to $93 per hour. And the highest annual income comes from the combined NP + PA portfolio: a physician holding one NP collaboration arrangement at $2,000 per month plus two PA Model 1 remote arrangements at $1,500 per month each earns $60,000 annually from a total time investment of approximately 10 to 14 hours per week. When a PA practice offers a physician options — which is uncommon but does happen, particularly in states with evolving regulatory frameworks — the physician should choose based on effective hourly rate and scalability, not nominal monthly fee. Model 1 or Model 2 with a strong volume cap and explicit no-exclusivity provision typically produces the best income outcome for a physician who is building a multi-arrangement portfolio. Understanding the missouri collaborative practice agreement framework and the michigan nurse practitioner collaborative agreement requirements, for example, helps physicians understand which models each state’s law supports — ensuring the model they agree to actually satisfies state-specific oversight requirements.
Which PA Arrangement Model Fits Which Physician Specialty: The Match Matrix
Not every physician specialty is equally suited to every PA oversight model. The match between a physician’s clinical background and the PA practice’s scope is important — and so is the match between the physician’s preferred work style and the specific oversight model the arrangement requires.
| Physician Specialty | Best-Fit PA Model(s) | Why This Match Works | Monthly Rate Potential | State Market Notes |
|---|---|---|---|---|
| Family Medicine / Primary Care | Model 1Model 2 | Broadest PA practice type compatibility; outpatient primary care PA oversight is natural for FM; telehealth PA primary care oversight requires no specialty adjustment | $1,200–$2,400 | Active in all required-supervision states; highest volume market for FM physicians in Model 1 |
| Internal Medicine | Model 1Model 2 | Complex chronic disease PA practices prefer IM oversight; metabolic health, multicomorbid patients, and complex medication management benefit from IM clinical depth | $1,500–$2,800 | Premium over FM rate reflects clinical depth; active in both required and voluntary-PA states |
| Surgery / Orthopedics / ENT | Model 3Model 5 | Surgical PA practices frequently require on-site supervision for procedural activities; CS prescribing for post-op pain is a common oversight need; specialty match is clinically important | $1,500–$3,000 | On-site model dominates in surgical settings; specialty match expected by PA practices and state boards |
| Emergency Medicine | Model 3Model 5 | EM PA practices in many settings require immediate physician availability; acute care CS prescribing for pain and procedure sedation is common; real-time consultation availability is a core feature | $1,200–$2,800 | Hospital-based EM PA practices typically use Model 3; independent urgent care PA telehealth may qualify for Model 2 |
| Dermatology | Model 1Model 4 | Dermatology PA practices in states with remote supervision provisions benefit from specialty-matched asynchronous oversight; teledermatology PA practices are ideally suited to Model 2; specialty scarcity drives premium rates | $1,800–$3,500 | Specialty scarcity premium applies; dermatologist oversight of derm PA practices commands highest rates in the PA market |
| Psychiatry / Behavioral Health | Model 1Model 2 | Behavioral health PA practices — particularly telehealth psychiatric PA practices in required-supervision states — need psychiatrist or behavioral health physician oversight; specialty premium applies; telehealth behavioral health PA market growing rapidly | $2,000–$3,800 | Behavioral health PA practices growing in same states as behavioral health NP practices; psychiatrists who participate in PA oversight market command premium alongside their NP oversight income |
| Addiction Medicine | Model 1Model 5 | Addiction medicine PA practices frequently need both general oversight and MAT/buprenorphine CS delegation; physician must hold active DEA; buprenorphine delegation creates CS premium above baseline remote rate | $1,500–$3,000 | Active in states with high addiction medicine demand; CS delegation component is essential to the arrangement scope |
How Physicians Build Maximum Income From PA Arrangements — Model Selection and Portfolio Strategy
The key insight that emerges from mapping all six PA oversight models is that the income-optimized strategy is almost always to favor Models 1 and 2 — remote asynchronous and telehealth-only oversight — over Models 3 and 6, which require more time, impose location constraints, and typically include exclusivity provisions that limit income scalability. The remote models pay less per arrangement at the nominal monthly fee level, but generate more income per hour and permit the stacking of multiple arrangements that compounds annual income dramatically.
A physician holding two Model 1 PA remote oversight arrangements at $1,800 per month each, plus two NP collaboration arrangements at $2,000 per month each, earns $91,200 annually from approximately 14 to 20 hours of total weekly oversight work — with no exclusivity restriction, no location constraint, and no non-compete clause limiting future income growth. That portfolio is not a hypothetical — it is being built by physicians in required-supervision and required-collaboration states who understand both markets and have strategically licensed themselves into the highest-demand states for each.
The state-specific knowledge of where your license creates PA oversight demand — combined with knowing which model each state’s PA practice act requires or permits — is what allows physicians to target their licensing strategy for maximum income rather than accepting whatever arrangement type the first PA practice offers.
Can a physician hold multiple PA arrangement models simultaneously — and does mixing models create any compliance complications?
Yes, a physician can simultaneously hold multiple PA oversight arrangements using different models — for example, a remote asynchronous arrangement (Model 1) with one PA practice, a telehealth-only arrangement (Model 2) with a second PA practice, and a consultation-protocol arrangement (Model 4) with a third — without inherent legal conflict between the different models. Each arrangement is governed independently by the agreement between the physician and that specific PA practice, and each must individually satisfy the requirements of the state in which the PA practices. The compliance implications of mixing models are practical rather than legal: a physician who holds three simultaneous arrangements of different types must maintain separate oversight documentation for each, manage separate review schedules, and ensure that the total time commitment across all arrangements remains manageable. The practical limit most physicians report is four to six simultaneous arrangements across all models combined — beyond which the administrative complexity and documentation burden becomes difficult to manage without dedicated tracking systems. The mixing of PA and NP arrangements is similarly permissible and does not create compliance complications: PA oversight arrangements are governed by state PA practice acts and PA supervision agreement law; NP collaboration arrangements are governed by state NP practice acts and collaborative practice agreement law. The two bodies of law operate independently, and holding arrangements under both creates no conflict. The only caution is Model 6 medical director hybrid arrangements — their non-compete provisions should be reviewed carefully before adding any other arrangement of the same specialty in the same geographic market, as a broadly drafted non-compete could inadvertently restrict other PA or NP arrangements the physician wants to maintain.
The most common mistake physicians make when entering PA oversight arrangements: agreeing to a compensation structure that reflects one model while unknowingly accepting obligations from a more demanding model. A physician who is offered $1,500 per month — appropriate for Model 1 remote asynchronous oversight — but whose agreement language includes weekly on-site availability requirements (Model 3 obligations) has accepted a Model 3 time commitment at a Model 1 price. Read agreement obligations before rate; the obligations determine the model; the model determines what compensation is appropriate.
When evaluating any PA oversight arrangement, ask these four questions in order: (1) Does this state’s PA practice act permit the model the practice is proposing — specifically regarding physical presence, chart review percentage, and CS prescribing delegation? (2) What are the actual obligations as written in the agreement — chart review percentage, consultation availability hours, CS scope, any meeting requirements? (3) What is the implied oversight model based on those obligations — remote async, on-site, consultation-protocol, or hybrid? (4) Does the compensation reflect market rate for that model type — or does it reflect a lower model’s rate for a higher model’s obligations? Answers to these four questions define the arrangement more accurately than any title or label in the agreement document.

Find PA and NP Arrangements in Your State →Six Models, One Decision: Choosing the PA Oversight Model That Fits Your Income Strategy
The physician assistant collaboration arrangement market is not a single product. It is a menu of six distinct models — each with its own time requirement, income structure, scalability profile, and state-specific compatibility — that physicians can evaluate, select, and combine into an income portfolio that matches their professional goals and schedule constraints.
The physician who enters the PA oversight market without understanding this model landscape will accept whatever the first PA practice offers — which may be a Model 3 on-site commitment priced at Model 1 rates, or a Model 4 consultation arrangement from a state that actually requires Model 1 chart review to be legally compliant. Both are expensive mistakes that could have been avoided by understanding the full model landscape before the first arrangement conversation.
With that understanding now in hand: the income-optimized strategy for most physicians is Model 1 or Model 2 remote oversight, stacked across two to four simultaneous arrangements in required-supervision states, combined with a parallel NP collaboration income stream from the same or adjacent state licenses. That combination produces the highest annual income, the highest effective hourly rate, and the most flexible schedule of any physician oversight income model currently available in the market.
PA arrangement model descriptions and state-specific requirements in this guide reflect the regulatory landscape as of 2025–2026.
