Louisiana collaborating physician requirements apply to a permanent restricted-practice market with one of the most board-intensive approval structures in the country. Louisiana does not grant nurse practitioners full practice authority. Every APRN who engages in acts of medical diagnosis, prescription, or management must practice under a Louisiana State Board of Nursing-approved Collaborative Practice Agreement with a qualifying physician. The CPA must be submitted to and approved by the LSBN before the APRN may exercise prescriptive authority.
For physicians considering a collaboration role in Louisiana, the compliance obligations include board approval before prescribing begins, a comparable specialty standard, an alternate physician designation requirement, strict availability rules that prohibit prescribing when the physician is unreachable, and a 30-day notification window for any changes. This guide covers every requirement a physician needs to understand in 2026, sourced directly from Louisiana Revised Statutes and Louisiana Administrative Code.
Louisiana Collaborating Physician Overview: Where Louisiana Stands
Louisiana classifies APRNs in the restricted-practice category with no independence pathway. There is no experience threshold, no hours accumulation process, and no legislative movement toward full practice authority for NPs in Louisiana as of 2026. Physician collaboration is a career-long legal requirement under R.S. 37:913 and LAC 46:XLVII.
Governing Bodies
Two regulatory bodies govern these arrangements:
- Louisiana State Board of Nursing (LSBN): Governs APRN licensure, CPA review and approval, prescriptive authority certification, controlled substance authority applications, and disciplinary matters under R.S. 37:911 et seq. and LAC 46:XLVII.
- Louisiana State Board of Medical Examiners (LSBME): Governs physician licensure, standards of medical practice in collaborative arrangements, and disciplinary oversight of physicians involved in CPAs under the Louisiana Medical Practice Act.
Both boards can independently investigate compliance failures. A complaint involving an APRN can surface questions about the collaborating physician’s qualifications and availability, and vice versa.
CRNAs: A Separate Framework
Certified Registered Nurse Anesthetists in Louisiana are not required to have a collaborative practice agreement to provide anesthesia care and ancillary services to patients in a hospital or other licensed surgical facility. This exclusion is confirmed under LAC 46:XLVII.4513. CRNAs practicing in non-hospital or outpatient settings should verify the applicable rules for their specific context with the LSBN.
The Collaborative Practice Agreement: Louisiana’s Core Compliance Document
Under R.S. 37:913(9), a collaborative practice agreement is defined as a formal written statement addressing the parameters of the collaborative practice which are mutually agreed upon by the advanced practice registered nurse and one or more licensed physician or dentist. Acts of medical diagnosis and prescription by an APRN must be in accordance with a collaborative practice agreement unless otherwise provided in R.S. 37:930.
The CPA is not effective upon signing. The LSBN must review and approve the agreement before the APRN may exercise prescriptive authority. APRNs are required to use the LSBN’s official CPA template. Parties may add supplemental pages to address the specific clinical context of their arrangement, but the template structure must be followed.
The CPA Must Be Maintained at the Clinical Site
Under LSBN rules, a copy of the signed CPA and all prescriptive authority approval letters issued by the LSBN must be maintained at the clinical site where prescriptive authority privileges are exercised. The agreement must be available for review during any site visit by either board.
The CPA Remains in Effect Until Cancelled
Once approved by the LSBN, the CPA remains in effect until one or more of the collaborating professionals notify the LSBN in writing to cancel the agreement. There is no automatic expiration date. The agreement does not expire on a set cycle the way it does in states like Georgia or Tennessee.
What Must Be in a Louisiana CPA
Louisiana Revised Statutes § 37:913(9) and LAC 46:XLVII.4513 specify the minimum required content of a valid collaborative practice agreement. The agreement must address all of the following:
1. Availability of the Collaborating Physician
The CPA must document the availability of the collaborating physician for consultation, assistance with medical emergencies, or patient referral when the physician is not physically present in the practice setting. The APRN may not prescribe if the collaborating physician or dentist is not available physically, by telephone, or by direct telecommunications.
2. Methods of Practice Management Including Clinical Practice Guidelines
The agreement must include methods of management of the collaborative practice. These methods must include clinical practice guidelines that are mutually agreed upon by both parties, consistent with current standards of care and evidence-based practice for the APRN’s specialty, and document the types, categories, and schedules of drugs available for prescription by the APRN.
3. Coverage of Patient Care During Absences
The CPA must address coverage of the health care needs of patients during any absence of the APRN, the physician, or both parties. The coverage plan must specify how patient care will continue when either party is unavailable.
4. Plan of Accountability
Under LAC 46:XLV.7911, the CPA must include a plan of accountability that addresses the prescriptive authority of the APRN and the responsibilities of the collaborating physician, a plan for hospital and other healthcare institution admissions and privileges, arrangements for diagnostic and laboratory testing, and a plan for documentation of medical records.
5. Alternate Collaborating Physician Designation
The CPA must include identification of an alternate collaborating physician and an organizational policy that allows and provides for designation of that alternate. The alternate must meet all conditions required of the approved primary collaborating physician.
6. DEA Schedule Authorization
If the APRN will prescribe controlled substances, the CPA must identify the requested DEA schedules. Louisiana uses a tiered controlled substance authorization structure, and the specific schedule levels must be named in the agreement.
Board Approval: How the Process Works
Louisiana’s CPA approval requirement is one of the most consequential compliance steps in the state’s framework. The APRN must submit the CPA to the LSBN for review and approval through the LSBN Nurse Portal before prescriptive authority can be exercised.
The Submission Process
The APRN submits the completed CPA along with the prescriptive authority application and associated documentation through the Nurse Portal. The physician does not submit separately but must confirm that the APRN has submitted the required materials before any prescribing begins. The LSBN reviews the submission and notifies the APRN of approval or denial through the Portal.
Controlled Substance Authority Requires Additional Steps
If the APRN is applying for controlled substance prescriptive authority, additional documentation is required. The APRN must submit a detailed letter describing the clinical need for controlled substance privileges within the patient population served by their practice. A three-hour board-approved continuing education course on controlled substance prescribing practices must also be submitted as part of the application. The specific DEA schedule levels requested must be identified in the CPA and in the application materials.
The Physician’s Obligations at Approval
The collaborating physician must ensure the CPA is complete and compliant before signing. The physician also completes a Registration as a Supervising Physician on the LSBME website when entering into a Louisiana collaboration arrangement. The registration on the LSBME side is separate from the LSBN’s CPA review process.
Physician Eligibility: Active Practice and Specialty Comparability
Under LAC 46:XLV.7911 and LSBN guidance, a qualifying Louisiana collaborating physician must meet all of the following:
Active Louisiana Practice Required
The physician must be actively engaged in the provision of direct patient care in Louisiana. This is not a residency requirement, but it does mean the physician must be practicing clinical medicine in Louisiana, not merely holding a Louisiana license without active patient care activity in the state. Collaborating physicians who have moved their practice out of Louisiana or who are no longer actively seeing patients do not meet this standard.
Current Unencumbered License
The physician must hold a current and valid medical license issued by the LSBME, in good standing with no pending disciplinary proceedings.
Specialty Comparability
The physician must practice in an area comparable in scope, specialty, or expertise to that of the APRN. This is a substantive standard, not a paperwork requirement. The clinical overlap between the physician’s practice and the APRN’s specialty must be genuine. A physician whose day-to-day practice has no meaningful relationship to the APRN’s clinical focus does not meet this standard.
No Geographic Proximity Requirement
Louisiana does not impose a geographic proximity requirement on collaborating physicians. A physician practicing in Shreveport can collaborate with an APRN clinic in New Orleans without any distance restriction. What Louisiana requires is availability, not proximity.
No Ratio Limit
Louisiana does not impose a statutory cap on the number of APRNs a physician may collaborate with simultaneously. The physician must be genuinely available to each APRN they collaborate with, and the availability obligation is the practical constraint on how many concurrent arrangements are sustainable.
The Alternate Collaborating Physician Requirement
Louisiana is one of a small number of states that requires an alternate collaborating physician to be identified in the CPA itself and confirmed through an organizational policy allowing for that designation.
Who the Alternate Must Be
Under LAC 46:XLVII.4505, an alternate collaborating physician is a physician designated by the primary collaborating physician, previously approved to collaborate with the APRN by the LSBN, who agrees to serve in this capacity. The alternate must be actively engaged in clinical practice and the provision of direct patient care in Louisiana and must hold a current, valid Louisiana medical license. Importantly, the alternate must be engaged in clinical practice in the same or a comparable scope, specialty, or expertise to that of the APRN.
Why This Matters
The alternate physician designation is not optional or informal. It must be documented in the CPA. When the primary collaborating physician is unavailable, the alternate assumes responsibility for consultation and collaboration. If no alternate is named and the primary physician becomes unavailable, the APRN cannot prescribe. The alternate physician provides the coverage structure that keeps the APRN’s prescriptive authority active when the primary physician cannot be reached.
Prescriptive Authority and Controlled Substances in Louisiana
Louisiana uses a tiered controlled substance prescriptive authority system that is more granular than most other states. The APRN’s prescriptive authority is not a single approval covering all scheduled substances. Instead, the specific DEA schedule levels must be identified in the CPA and separately approved by the LSBN.
The Schedule Tiers
Louisiana distinguishes between the following controlled substance authorization levels, all of which must be specified in the CPA:
- Schedules III through V: The base level of controlled substance authority for APRNs with the relevant application approval
- Schedule II non-narcotic (ADD/ADHD medications): Separately authorized; stimulants such as methylphenidate and amphetamine salts fall in this category
- Full Schedule II narcotics: The most expansive controlled substance authority, requiring the highest level of clinical justification in the application letter
APRNs must apply specifically for each tier they need. The LSBN does not automatically upgrade an APRN’s controlled substance authority when schedules change. When a drug is reclassified, the APRN must submit documentation requesting the change.
DEA and State Registration
An APRN authorized to prescribe controlled substances must provide their DEA registration number on all written, electronic, oral, or faxed prescriptions for controlled substances. Both a DEA registration and a Louisiana state controlled dangerous substance license are required before controlled substance prescribing may begin.
The No-Prescribing Rule When Physician Is Unavailable
Under R.S. 37:913 and the LSBN CPA template, if the collaborating physician or dentist is not available physically, by telephone, or by direct telecommunications, the APRN will not prescribe. This prohibition is absolute. It applies regardless of the clinical circumstances and regardless of whether the alternate physician is also unavailable. If no physician is reachable, prescribing must stop.
The APRN Cannot Prescribe When the Physician Is Unavailable
This rule deserves particular attention because it is among the strictest availability standards of any state in the country. The prohibition on prescribing when the physician is unavailable is not a best-practice recommendation. It is a regulatory requirement built directly into the CPA template that every Louisiana APRN must sign.
Practical Implications for Physicians
A physician who enters a Louisiana collaboration arrangement must maintain genuine, consistent availability to the APRN during practice hours. Physicians who frequently travel, take extended periods of unreachability, or regularly go days without telecommunications access are creating conditions under which the APRN cannot legally prescribe.
The alternate physician designation is the mechanism for managing planned absences. When the primary physician knows they will be unavailable, the alternate physician takes over the availability obligation. An arrangement with no alternate physician and a primary physician who is periodically unreachable creates recurring compliance gaps.
Termination and Change Notification Obligations
The APRN’s 30-Day Notification Window
The APRN must notify the LSBN in writing within 30 days of all changes regarding prescriptive authority, including the addition or deletion of collaborating physicians or practice sites. This notification window applies to any material change in the arrangement, not just full terminations.
Cancellation of the Agreement
Once approved by the LSBN, the CPA remains in effect until one or more collaborating professionals notify the LSBN in writing to cancel. Either the physician or the APRN may initiate the cancellation. The written notice to the LSBN is the official act that closes the arrangement on the board’s records.
LSBN Registration as Supervising Physician
Physicians entering Louisiana collaboration arrangements must also complete a Registration as a Supervising Physician on the LSBME website. This registration is separate from the LSBN’s CPA review process and must be completed on the physician side of the arrangement.
Common Compliance Mistakes Louisiana Collaborating Physicians Make
Most Louisiana CPA compliance problems involve availability gaps, specialty mismatches, and failure to properly handle the alternate physician designation.
- No alternate physician named in the CPA. The alternate must be identified in the agreement and supported by an organizational policy. An arrangement with no named alternate leaves the APRN without a coverage structure when the primary physician is unavailable and creates conditions under which prescribing must stop.
- Alternate physician not meeting all eligibility requirements. The alternate must be actively practicing in Louisiana, hold a current LSBME license, and practice in a comparable scope or specialty to the APRN. An alternate who does not meet these requirements is not a valid substitute.
- Physician not actively practicing in Louisiana. The physician must be actively engaged in direct patient care in Louisiana. A physician who holds a Louisiana license but is no longer practicing in the state does not satisfy the active practice requirement.
- Controlled substance schedule not specified in the CPA. The DEA schedule levels authorized must be named in the CPA. A general statement that the APRN is authorized to prescribe controlled substances without identifying the specific schedule tiers does not satisfy the requirement.
- Prescribing allowed when physician is unreachable. The prohibition on prescribing when the physician is unavailable is absolute. Physicians who are aware that their APRN continues to prescribe during periods of unavailability are party to a compliance violation.
- LSBME registration not completed. Physicians must complete a Registration as a Supervising Physician on the LSBME website separately from the LSBN CPA process. Missing this step leaves the physician’s side of the arrangement unregistered.

Clinics Also Need to Understand Louisiana Collaboration Requirements
While this guide primarily covers the responsibilities and compliance requirements placed on collaborating physicians in Louisiana, these regulations directly affect APRN-owned clinics, medspas, and healthcare practices that depend on physician collaboration to operate. In many cases, clinic owners researching Louisiana collaboration rules are also trying to understand how to find a qualified physician who is actively practicing in Louisiana, whose clinical background is comparable to the APRN’s specialty, and who can serve as the primary available contact the APRN needs to legally prescribe at every practice session.
Need Help Finding a Louisiana Collaborating Physician?
For clinics, understanding the legal requirements is only one part of the process. The next challenge is finding a qualified physician who meets Louisiana’s active clinical practice standard, holds a current LSBME license in good standing, practices in a scope comparable to the APRN’s specialty, and understands the no-prescribing rule that makes genuine availability a legal necessity rather than a general expectation. Whether you are launching a new clinic, replacing a physician whose CPA has been cancelled, or adding a new practice site that requires an updated CPA filing with the LSBN, having the right physician in place before the board review is completed matters.
If your clinic is actively looking for a Louisiana collaborating physician, our team can match you with a qualified physician, often within 24 to 48 hours. We work with clinics across Louisiana to simplify the physician matching process while supporting CPA drafting, LSBN Nurse Portal submissions, controlled substance schedule applications, and long-term collaboration needs.
Final Thoughts
Louisiana collaborating physician requirements are built around a board-approval framework that makes LSBN sign-off a prerequisite for every prescription the APRN writes. The CPA is not a private agreement between two parties. It is a board-approved instrument, and any prescribing that precedes that approval is outside the legal framework from the first prescription.
For physicians entering the Louisiana market, the most important steps are confirming active Louisiana practice status, ensuring specialty comparability with the APRN’s clinical area, naming a qualified alternate physician in the CPA, completing the LSBME registration, and maintaining genuine availability throughout the collaboration so the no-prescribing rule never becomes a clinical emergency.

Frequently Asked Questions
Does a Louisiana collaborating physician need to be physically present at the APRN’s clinic?
The physician is not required to be physically present at the practice location. Louisiana does not impose a geographic proximity requirement. However, the physician must be available by telephone or direct telecommunications at all times when the APRN is practicing. If the physician is not available physically, by phone, or by direct telecommunications, the APRN may not prescribe. This no-prescribing rule is absolute.
Does a Louisiana CPA need to be filed with the board before prescribing begins?
Yes. The CPA must be submitted to the Louisiana State Board of Nursing through the LSBN Nurse Portal for review and approval. The APRN may not exercise prescriptive authority until the LSBN issues approval. The physician should confirm that approval has been received before the APRN begins any prescribing under the arrangement.
What is the alternate collaborating physician requirement in Louisiana?
The CPA must identify an alternate collaborating physician who can assume consultation and collaboration responsibilities when the primary physician is unavailable. The alternate must be actively practicing in Louisiana, hold a current LSBME license, and practice in a clinical area comparable to the APRN’s specialty. The alternate must also be confirmed through an organizational policy included in or attached to the CPA.
Can a Louisiana APRN prescribe Schedule II controlled substances?
Yes, with board approval. Louisiana uses a tiered controlled substance authority structure. APRNs may be authorized for Schedules III through V as a base level, Schedule II non-narcotics for ADD/ADHD separately, and full Schedule II narcotics at the highest tier. Each tier requires its own application documentation, including a detailed letter describing the clinical need and a three-hour CE certificate for initial controlled substance authority requests.
How many APRNs can one Louisiana physician collaborate with?
Louisiana does not impose a statutory ratio cap on the number of APRNs a physician may collaborate with. However, the physician must be genuinely available to every APRN they collaborate with, and the no-prescribing rule applies across all active arrangements. The practical constraint is the physician’s capacity to maintain real availability, not a numerical limit.
What happens when a Louisiana CPA is terminated?
The APRN must notify the LSBN in writing within 30 days of the deletion of a collaborating physician or a practice site that had been previously approved by the LSBN. The CPA remains in effect until one or more collaborating professionals notify the LSBN in writing to cancel. Once cancelled, the APRN’s prescriptive authority associated with that arrangement is inactivated.
