Mississippi collaborating physician requirements apply to a restricted-practice state with some of the most specific geographic and oversight obligations in the country. Mississippi does not grant nurse practitioners full practice authority. There is no independence pathway, no experience threshold that removes the physician requirement, and no transition period leading to autonomous APRN practice. A full practice authority bill that would have changed this framework failed in the Mississippi legislature in April 2025, leaving the collaboration requirement in place for the foreseeable future.
For physicians considering a collaboration role in Mississippi, the compliance obligations include a board notification requirement within seven working days, a 40-mile geographic proximity rule with a defined exception, a mandatory backup physician designation, an annual protocol review, and specific rules for acute care and emergency settings. Getting each of these right before and throughout the arrangement is what determines whether the collaboration is defensible. This guide covers every requirement a physician needs to understand in 2026, sourced directly from Mississippi statutes and board rules.
Mississippi Collaborating Physician Overview: Where Mississippi Stands
Mississippi classifies APRNs in the restricted-practice category with no expiration and no pathway to independence. Physician collaboration is a career-long legal requirement for every APRN who prescribes medications or provides advanced clinical care in the state.
Governing Bodies
Two regulatory bodies govern these arrangements:
- Mississippi State Board of Medical Licensure (MSBML): Governs physician licensure, collaboration standards, protocol filing, and disciplinary oversight of physicians in collaborative arrangements. The MSBML has published rules under Title 30, Part 2630 of its Administrative Code that define in detail what the standard of practice is for physicians in collaborative relationships with APRNs.
- Mississippi Board of Nursing (MSBN): Governs APRN licensure, prescriptive authority applications, controlled substance authority, and APRN practice site verification. The MSBN can investigate compliance failures independently and coordinate with the MSBML when both licensees are involved in the same arrangement.
Both boards retain independent authority to discipline their respective licensees. A complaint filed against an APRN can trigger scrutiny of the collaborating physician’s documentation, and a complaint against the physician can surface questions about the APRN’s compliance as well.
The 2025 Legislative Context
In April 2025, a full practice authority bill for Mississippi APRNs failed to pass in the state legislature. Mississippi remains a restricted-practice state, and the physician collaboration requirement continues in full force. Physicians considering long-term collaboration arrangements in Mississippi can plan around a stable regulatory environment that does not appear likely to move toward NP independence in the near term.
The Collaborative Protocol: Mississippi’s Core Compliance Document
Mississippi uses the term collaborative protocol rather than collaborative practice agreement or prescriptive authority agreement. The protocol is a written, signed, and dated agreement between the collaborating physician and the APRN that defines the scope of practice, the medication formulary, the shared responsibilities of both parties, and the procedures for handling emergencies and unexpected outcomes.
Without a current, signed protocol on file, the APRN has no legal framework for prescribing or providing advanced clinical care in Mississippi. The protocol is the foundation of every clinical act the APRN performs under the physician’s collaboration.
Primary and Secondary Collaborating Physicians
Mississippi recognizes both primary and secondary collaborating physicians. The primary collaborating physician is the physician who has executed the formal protocol and carries primary responsibility for the collaborative arrangement. A secondary collaborating physician may be designated to provide backup coverage when the primary physician is unavailable.
Both primary and secondary collaborating physicians are subject to the same eligibility requirements under the MSBML rules and must each meet the 40-mile proximity requirement unless the applicable exception applies.
What Must Be in a Mississippi Collaborative Protocol
Mississippi Board of Medical Licensure rules under Title 30, Part 2630 specify the required content of a valid collaborative protocol. Under Rule 1.3, the collaborative agreement must:
1. Remain at the Practice Site
The executed protocol must remain in the practice site of the APRN during any board site visit. The MSBML can appear at the practice location to review documentation, and the protocol must be physically present and available.
2. Define Scope of Practice
The protocol must define the scope of practice including mutually agreed-upon collaborative agreements and guidelines for the healthcare provided. The scope must be specific to the APRN’s training, certification, and the physician’s compatible specialty. A generic scope description that does not reflect the actual clinical services being provided creates a compliance gap.
3. Agree on a Medication Formulary
The protocol must include agreement on the medication formulary to be used by the APRN and physician in practice. The collaborating physician has the right to use the Mississippi Prescription Monitoring Program to review the APRN’s controlled substance prescribing practices. This is not optional. The formulary must be specifically agreed upon in the protocol.
4. Describe Individual and Shared Responsibilities
The protocol must describe the individual and shared responsibilities of both the APRN and the physician. Each party’s role must be clearly delineated. A protocol that lists only the APRN’s responsibilities without addressing the physician’s specific obligations does not meet this requirement.
5. Annual Review and Update
The protocol must be reviewed and updated annually by both the physician and the APRN. Each annual review must be documented. A protocol that has passed the one-year mark without a documented review is no longer current.
6. Emergency Procedures
The protocol must set out a procedure for handling patient emergencies, unexpected outcomes, or other urgent practice situations. The emergency plan must be specific enough to guide both parties when clinical situations arise outside the normal scope of the arrangement.
7. Quality Assurance Program
Each collaborative relationship must include and implement a formal quality assurance and quality improvement program maintained on-site and available for inspection by board representatives. The QA program must be sufficient to provide a valid evaluation of the practice and serve as a meaningful basis for clinical change when needed.
Board Filing Requirements: Submitting to the MSBML
Mississippi imposes a specific board notification obligation on physicians that distinguishes it from most other states.
The Seven Working Day Requirement
Under MSBML Rule 1.3(B), every primary and secondary collaborating physician must notify the Board within seven working days of entering into or termination of any collaborative agreement. This is one of the shortest notification windows of any state in the country.
A physician who begins a collaboration arrangement on Monday has until the following Wednesday to file notification with the MSBML. A physician who ends an arrangement must file the termination notice within the same seven-working-day window.
How to File
If a physician anticipates collaborating with an APRN, the physician must submit the required documentation through the MSBML’s online licensure gateway at gateway.msbml.ms.gov. Paper submissions are not the standard method. Physicians seeking to collaborate under the Primary Care Extended Mileage exception must also submit a separate letter through the gateway identifying the APRNs covered by the arrangement and affirmatively stating that the physician meets the extended mileage requirements.
Physician Eligibility: The Active Practice and Specialty Compatibility Standards
A Mississippi collaborating physician must hold a current unrestricted license to practice medicine in Mississippi. This is explicitly defined under MSBML rules: the physician must hold a current unrestricted license and must actively provide direct patient care for at least eight hours weekly. A physician whose license is restricted, whose practice is limited by a board order, or who does not meet the eight-hours-per-week direct patient care threshold is not eligible to serve as a collaborating physician.
Specialty Compatibility
Under MSBML Rule 1.3, a physician shall not enter into a collaborative agreement with an APRN whose training and practice is not compatible with that of the physician. This is a substantive standard, not a procedural one. The physician’s clinical background must be meaningfully compatible with the APRN’s training and practice area. A primary care physician cannot enter into a protocol with an APRN practicing in a clinical specialty in which the physician has no training or experience.
The rules do recognize specific exceptions for certain clinical models. It is recognized and accepted practice that surgeons, obstetricians, and dentists have collaborative arrangements with CRNAs in the anesthesia care team model.
Geographic Proximity: The 40-Mile Rule and Its Exceptions
Mississippi imposes one of the most specific geographic requirements of any state in the country. Under MSBML rules, a collaborative physician must be within 40 miles of the actively practicing APRN.
The Standard 40-Mile Requirement
Both primary and secondary collaborating physicians must satisfy the 40-mile requirement independently. If the primary physician is unavailable and a secondary physician is covering the arrangement, that secondary physician must also be within 40 miles of the APRN’s practice site. The distance is measured from the physician’s practice location to the APRN’s active practice site.
The Primary Care Extended Mileage Exception
Mississippi provides a specific exception to the 40-mile rule for qualifying primary care arrangements. The mileage restriction does not apply when all of the following conditions are met:
- The collaborative agreement is between a primary care physician and a primary care nurse practitioner
- The physician is in a compatible practice with the nurse practitioner (same specialty, treating the same patient population)
- The physician utilizes electronic medical records (EMR) in their practice, has direct access to the EMR used by the APRN, and also uses EMR in the formal quality improvement program
- The collaborating physician practices in Mississippi for a minimum of 20 hours per week or 80 hours per month. Telemedicine hours do not count toward this 20-hour weekly minimum
A physician who wishes to collaborate under this exception must submit a letter to the MSBML through the online gateway identifying the APRNs covered by the arrangement and affirmatively stating that the physician meets the extended mileage conditions.
Free Standing Clinic Definition
Mississippi defines a Free Standing Clinic as a clinic or facility where patients are treated by a nurse practitioner that is more than 75 miles away from the primary office of the collaborative physician. Licensed hospitals, state health department facilities, federally qualified community health clinics, and volunteer clinics are excluded from this definition. The Free Standing Clinic classification triggers additional regulatory considerations and should be confirmed with the MSBML and a healthcare attorney when applicable.
Backup Physician Requirements
Mississippi’s geographic proximity rule includes a direct obligation for backup coverage that physicians entering any arrangement must understand.
Alternate Physician Designation
The collaborating physician must designate an alternate collaborating physician for times when the primary collaborative physician is unavailable. Physicians with collaborative relationships must ensure backup physician coverage when they are outside the approved distance for the Extended Mileage exception or otherwise unavailable.
Backup Physician as Signatory
The backup physician must be a signatory to the collaborative protocol. A backup arrangement that is not documented in the protocol has no legal standing under Mississippi regulations.
When No Backup Can Be Secured
If securing backup coverage is not possible, the primary collaborator and the APRN may agree, via terms written explicitly in the protocol, that no patients will be seen when the primary collaborator is unavailable. This must be stated in the protocol itself; it cannot be an informal understanding between the parties.
Prescriptive Authority and Controlled Substances in Mississippi
Mississippi APRNs with full prescriptive authority may prescribe Schedule II through V controlled substances after completing a board-approved educational program and receiving controlled substance prescriptive authority from the Mississippi Board of Nursing.
The Monitored Practice Requirement
Before receiving controlled substance prescriptive authority, APRNs must complete a period of monitored practice hours as required by the MSBN. The application for DEA registration is not connected to monitored practice hours as of January 1, 2018, but the MSBN controlled substance prescriptive authority approval must be obtained before the APRN begins prescribing controlled substances.
Physician’s Role in the Formulary
The collaborative protocol must specify a medication formulary agreed upon by both the physician and the APRN. The physician has the right to access the Mississippi Prescription Monitoring Program to review the APRN’s controlled substance prescribing at any time. This monitoring right is expressly recognized in board rules and should be treated as an active oversight obligation rather than an optional review tool.
Schedule II Authorization
Unlike Georgia, which prohibits all Schedule II prescribing by APRNs, Mississippi allows APRNs to prescribe Schedule II through V controlled substances within the terms of the collaborative protocol and with proper board authority. The protocol’s formulary must reflect the specific controlled substance classes the APRN is authorized to prescribe.
Acute Care and Emergency Room Obligations
Mississippi imposes specific additional requirements when a collaborating physician’s APRN is working in acute care or emergency settings.
Acute Care Facilities
When an APRN is providing care in an acute care facility, there must be evidence reflected in the patient’s chart that a collaborating physician has seen and examined the patient within 12 hours of the APRN initially seeing the patient on admission. This chart documentation requirement applies regardless of whether the primary or secondary collaborating physician conducts the examination.
Emergency Rooms
When an APRN is working in or staffing an emergency room, the collaborative physician must be physically present in the building or no more than 10 minutes from the facility at all times. A board-approved telemanagement arrangement is the only recognized exception to this physical presence rule. This is one of the strictest proximity requirements for any specific practice setting in the country and eliminates the possibility of remote-only collaboration for ER-based APRN practice in Mississippi.
Termination Obligations and the 90-Day Grace Period
Mississippi provides a structured grace period for APRNs who lose their collaborating physician unexpectedly.
Physician Notification Obligation
When a collaboration terminates for any reason, the physician must notify the MSBML within seven working days of the termination. This is the same window that applies when the arrangement begins.
The 90-Day Grace Period
If an APRN is unable to secure a new collaborative physician after the termination of an existing arrangement, the Mississippi State Board of Medical Licensure or its designee may serve as the APRN’s collaborative physician with the agreement of the Mississippi Board of Nursing. The MSBN will assist the APRN in securing a new collaborative physician during this period. If a new collaborating physician has not been secured at the end of the 90-day period, an additional 90-day extension may be granted by mutual agreement of the Executive Committees of both boards.
Common Compliance Mistakes Mississippi Collaborating Physicians Make
Mississippi’s compliance requirements are specific enough that documentation failures are common even among physicians who understand their general obligations.
- Board notification not filed within seven working days. The notification window is among the shortest in the country. Physicians who delay filing even by a few days are out of compliance from the moment the window closes.
- Backup physician not designated as a signatory. The backup physician must sign the protocol. A verbal understanding or informal backup arrangement without a signed protocol entry has no regulatory standing.
- 40-mile rule not verified independently for backup physicians. The backup physician must satisfy the 40-mile requirement independently of the primary physician. A backup based more than 40 miles from the APRN’s practice site creates a compliance gap in the coverage structure.
- Active practice minimum not maintained. The physician must actively provide direct patient care for at least eight hours per week. A physician who has reduced their clinical hours below this threshold while continuing as a collaborating physician no longer meets the eligibility standard.
- Protocol not reviewed and updated annually. The annual review must be documented. A protocol that has passed the one-year mark without a review record is not current regardless of how specific it was when originally executed.
- Extended mileage letter not submitted to MSBML. A physician relying on the Primary Care Extended Mileage exception must submit a letter through the gateway affirmatively confirming eligibility. Relying on the exception without the required filing is a compliance failure from the start.
- Acute care chart documentation missing. When an APRN sees a patient in an acute care facility, a collaborating physician must see and examine the patient within 12 hours and that examination must be charted. Delegating this to a facility attending without ensuring proper documentation creates exposure for both the collaborating physician and the APRN.

Clinics Also Need to Understand Mississippi Collaboration Requirements
While this guide primarily covers the responsibilities and compliance requirements placed on collaborating physicians in Mississippi, these regulations directly affect APRN-owned clinics, medspas, and healthcare practices that depend on physician collaboration to operate. In many cases, clinic owners researching Mississippi collaboration rules are also trying to understand how to find a qualified physician who meets the eight-hours-per-week active practice standard, satisfies the 40-mile proximity requirement, and can provide a backup physician who is also documented as a signatory to the protocol.
Need Help Finding a Mississippi Collaborating Physician?
For clinics, understanding the legal requirements is only one part of the process. The next challenge is finding a qualified physician who is available, practices in Mississippi at the required minimum hours, is within 40 miles of the clinic location or meets the extended mileage exception, and has specialty training compatible with the APRN’s practice area. Whether you are launching a new clinic, managing the 90-day grace period after losing a collaborating physician, or replacing a physician whose arrangement terminated, having the right physician relationship in place quickly is essential in a state with a seven-working-day notification requirement.

Frequently Asked Questions
Does a Mississippi collaborating physician need to be physically present at the APRN’s clinic?
Not for routine outpatient clinic settings, but the physician must be within 40 miles of the actively practicing APRN under standard collaboration rules. For emergency room settings, the collaborating physician must be physically present in the building or no more than 10 minutes from the facility. For acute care facility admissions, the collaborating physician must see and examine the patient within 12 hours of the APRN initially seeing the patient on admission.
How quickly does a Mississippi physician need to notify the Board after entering a collaboration?
Within seven working days of entering into or terminating any collaborative agreement, the physician must notify the Mississippi State Board of Medical Licensure through the online licensure gateway. This is one of the strictest notification timelines of any state in the country.
What is the 40-mile rule in Mississippi?
The standard geographic proximity requirement for Mississippi collaborative physicians is that the collaborating physician, both primary and secondary, must be within 40 miles of the actively practicing APRN. The Primary Care Extended Mileage exception removes this restriction for qualifying primary care arrangements where the physician and APRN share a compatible primary care specialty, both use EMR with the physician having direct access, and the physician practices in Mississippi for at least 20 hours per week.
Can Mississippi APRNs prescribe Schedule II controlled substances?
Yes. Unlike Georgia, which prohibits Schedule II prescribing entirely for APRNs, Mississippi allows APRNs with board-approved controlled substance prescriptive authority to prescribe Schedule II through V controlled substances within the terms of the collaborative protocol and their formulary agreement. The APRN must have completed a board-approved educational program and received MSBN controlled substance prescriptive authority approval before prescribing.
What happens if a Mississippi APRN cannot find a new collaborating physician after losing their physician?
The Mississippi State Board of Medical Licensure or its designee may serve as the APRN’s interim collaborative physician with the agreement of the Mississippi Board of Nursing for an initial 90-day grace period. The MSBN will assist the APRN in securing a new physician during this period. If no replacement is found within 90 days, a mutual agreement between the Executive Committees of both boards may grant an additional 90-day extension.
How many APRNs can one Mississippi physician collaborate with?
Mississippi does not specify a ratio limit for the number of APRNs a physician may collaborate with simultaneously under the standard collaboration rules. The CRNA anesthesia care team model is recognized as an acceptable exception where one anesthesiologist may work with up to four CRNAs concurrently. For all other APRN types, no numerical cap is established by MSBML rules.
