Texas collaborating physician requirements are among the most structured in the country. Texas does not grant nurse practitioners full practice authority. NPs must operate under written delegation agreements with a physician to prescribe medications, diagnose patients, and manage clinical protocols. That means every NP-owned or NP-operated clinic in Texas depends on a qualified, properly registered collaborating physician to function legally.
For physicians exploring this type of supplemental role, understanding the full compliance picture before signing anything is essential. The Texas Medical Board enforces these rules actively, and both the physician and the NP can face disciplinary action when something is not done right. This guide covers what the law requires, what the documentation looks like, and what compliance actually demands day to day.
Texas Collaborating Physician Overview: Where Texas Stands
Texas is a restricted-practice state for nurse practitioners. That classification matters because it defines the entire framework a collaborating physician steps into when agreeing to work with an NP or PA in the state.
In full-practice-authority states, NPs can diagnose, prescribe, and operate practices without physician oversight. Texas does not permit that. State law ties key aspects of NP practice, most notably prescriptive authority, directly to physician delegation. The physician is not just a name on a document. They are the legal anchor of the NP’s ability to prescribe and manage patients.
Two governing bodies share oversight of these arrangements:
- Texas Medical Board (TMB): Governs physician delegation, prescriptive authority agreements, and registration requirements.
- Texas Board of Nursing (TBON): Regulates NP licensure, scope of practice, and APRN credentialing.
Both boards can investigate compliance failures and take action against both the physician and the NP involved. Understanding what each party is responsible for is the first step toward a defensible arrangement.
Who Qualifies as a Collaborating Physician in Texas
A Texas collaborating physician must hold a full, active, and unrestricted Texas medical license (MD or DO). The TMB is specific about eligibility. Physicians are not eligible to register online if their license is under a current board order, if they have notified the TMB that they are not actively practicing medicine, or if they hold a temporary physician or Faculty Temporary License. A physician is also not eligible to delegate prescriptive authority if they are licensed under Voluntary Charity Care Status or hold a Telemedicine, Public Health, or Conceded Eminence license.
Specialty is generally not a barrier in most outpatient settings. The law does not require specialty alignment between the physician and the NP in most practice types. However, the physician must have competence for the oversight tasks they take on and must be able to fulfill quality assurance obligations related to the clinical area. For high-risk settings like controlled substance prescribing or psychiatric practice, specialty alignment becomes more practically important even if not always legally mandated.
Texas Practice Authority Classification
Texas places NPs in the restricted-practice category, which means career-long physician supervision is required. There is no pathway to independent NP practice after accumulating experience hours, the way states like California and New York have established. In Texas, the collaboration requirement does not expire. Every NP who prescribes medications needs a valid, signed Prescriptive Authority Agreement with a registered physician for the entire duration of their practice.
The Prescriptive Authority Agreement: The Core Compliance Document
The Prescriptive Authority Agreement, commonly called a PAA, is the foundation of every Texas collaborating physician arrangement. Without it, the NP has no legal authority to prescribe medications or controlled substances. Getting this document right is the most important compliance task for any physician entering a Texas collaboration.
Under Texas Occupations Code §157.0512, a physician may delegate to an advanced practice registered nurse or physician assistant, acting under adequate physician supervision, the act of prescribing or ordering a drug or device as authorized through a prescriptive authority agreement between the physician and the advanced practice registered nurse or physician assistant.
The PAA is not a formality. It is a binding legal instrument that defines what the NP can prescribe, how the physician will supervise, and what happens when something goes wrong.
What Must Be in a Texas PAA
Texas law specifies exactly what a PAA must contain at a minimum. A prescriptive authority agreement must, at a minimum: be in writing and signed and dated by the parties to the agreement; state the name, address, and all professional license numbers of the parties; state the nature of the practice, practice locations, or practice settings; identify the types or categories of drugs or devices that may be prescribed or the types or categories that may not be prescribed; provide a general plan for addressing consultation and referral; provide a plan for addressing patient emergencies; state the general process for communication and the sharing of information between the physician and the NP or PA related to patient care and treatment.
The agreement must also include a quality assurance and improvement plan. This plan must specify methods for documenting chart reviews and periodic meetings. The number of charts to be reviewed is determined by the physician and NP together, but the meetings must occur at a set minimum frequency.
In addition to these mandatory elements, the PAA must:
- Designate one or more alternate physicians who can provide supervision when the primary physician is unavailable
- Be reviewed and re-signed at least once a year, with annual review dates and signatures documented
- Be made available to the TMB or TBON within three business days of a request
- Accurately reflect how care is actually being delivered in practice, not just how the parties intend to practice
One practical note: the PAA must be produced quickly on request. If your documentation does not match real-world practice, that gap becomes a compliance problem the moment a board investigator asks for the file.
Registering the PAA with the TMB
A written PAA alone is not enough. Texas Occupations Code 157.0511 requires physicians to register with the TMB if the physicians delegate prescriptive authority to PAs or APNs. The physician must register through the TMB’s Online Supervision and Prescriptive Delegation Registration System before the NP begins prescribing under the agreement.
Any changes to the delegation, including adding NPs, changing practice locations, or modifying the scope of the arrangement, must be updated in the system within 30 days. Hard copy forms are no longer accepted.
NP-to-Physician Ratio and Supervision Limits in Texas
One of the most frequently misunderstood Texas collaborating physician requirements is the cap on how many NPs a single physician can supervise at the same time. The rule is specific and the exception is narrow.
In facility-based hospital practices and in practices that serve medically underserved populations, there are no limitations. In all other practice settings, one physician may delegate to no more than seven full-time equivalent APRNs and PAs (1:7 FTEs).
This limit applies across all non-hospital, non-underserved settings. An outpatient clinic physician collaborating with NPs at multiple private practices counts all of those relationships together toward the seven FTE cap. If you are working with three clinics and each has two full-time NPs, you are at six out of seven and near the limit.
The exception for medically underserved areas is meaningful for physicians in those markets. For most outpatient and commercial clinic settings, the 1:7 rule applies without exception.
Geographic Proximity Requirements
Texas does not impose a geographic proximity requirement on collaborating physicians. SB 406 eliminated site-based prescriptive authority. The law is silent regarding the practice location of the physician and its proximity to the practice site of the APRN or PA.
That said, the same source is clear that this does not eliminate the supervision obligation. In any given case, the distance between a physician’s primary practice and the practice site at which the physician’s delegates provide medical services may be an important factor in determining the quality of the physician’s supervision. All prescriptive delegation requires adequate supervision under the Medical Practice Act.
In practical terms, Texas allows remote collaboration. A physician in Dallas can collaborate with an NP in Houston. But the physician must still provide real supervision, respond to clinical questions, conduct chart reviews, and attend monthly meetings. Distance does not reduce the oversight obligation.
Quality Assurance Requirements: What Ongoing Supervision Looks Like
The Texas collaborating physician model requires active, documented oversight. This is not a sign-once-and-forget arrangement. The PAA must describe a quality assurance plan, and both parties must actually follow it.
Texas law requires periodic meetings between the physician and the NP. These meetings must take place at least once a month, in a manner determined by both parties. The meetings must include discussion of patient treatment and care, needed changes in patient care plans, and referral-related issues.
Every meeting must be documented. If a TMB investigator opens a file on a Texas collaboration and there are no meeting records, the assumption is that the meetings did not happen.
Chart Review Requirements
The PAA must specify chart review as part of the quality assurance plan. The number of charts to be reviewed is set by mutual agreement between the physician and the NP, meaning there is no mandatory minimum number set by law. However, the review must actually happen and must be documented.
Best practice is to pick a chart review volume you will actually maintain and document every review with dated records. A chart review that exists on paper but was never conducted creates more legal exposure than a smaller but consistently completed review process.
Controlled Substance Prescribing
Texas places additional conditions on the prescribing of controlled substances. Prescribing Schedule II medications requires direct physician involvement and stricter documentation. The PAA must define exactly which controlled substances are authorized under the agreement, and the physician’s DEA number must appear on any prescription for a controlled substance written by the NP.
For controlled substances, the physician’s DEA number is required to be included on the prescription drug order.
Physicians who do not want to be involved in Schedule II prescribing need to explicitly exclude those drug classes in the PAA. Leaving that section vague or silent creates ambiguity that can become a compliance problem.
What Happens at Inspection and Board Investigations
Texas collaborating physicians need to be prepared for two types of regulatory scrutiny: routine inspections and formal board investigations triggered by complaints. Both require the same documentation, so maintaining a ready compliance file at all times is the safest approach.
When the TMB opens an investigation involving a prescriptive authority arrangement, they will ask for the PAA, meeting documentation, chart review records, the delegation registration in the TMB system, and any documentation of license disclosure that should have occurred before the PAA was signed.
Prior to signing a prescriptive authority agreement, a licensee must disclose to the other party to the prescriptive authority agreement any prior disciplinary action by the board. This disclosure obligation applies to both the physician and the NP. Skipping it creates a compliance gap before the arrangement even starts.
Both the TMB and TBON can act freely or cooperatively when investigating compliance failures. That means a complaint filed against an NP can trigger scrutiny of the collaborating physician’s documentation and vice versa. The physician’s compliance file needs to be complete and current regardless of which party the investigation originates from.
Common Compliance Mistakes Texas Collaborating Physicians Make
Most Texas collaborating physician compliance problems come down to documentation, not intent. Physicians generally understand their obligations but underestimate how much proof regulators expect to see. Here are the most common failure points:
- Stale PAAs. Agreements must be reviewed and re-signed annually. Many arrangements remain on the original agreement long past the one-year mark. Each annual review needs a documented date and both parties’ signatures.
- No delegation registration update. Adding a new NP or changing a practice location requires updating the TMB system within 30 days. Physicians who collaborate with multiple clinics often miss updates when staffing changes.
- Missing meeting documentation. Monthly meetings must happen and must be documented. A general note that meetings occurred is not enough. Records should capture what was discussed, who was present, and any follow-up actions.
- Vague PAA scope. Agreements that list broad drug categories without specifying excluded substances or procedures create compliance risk. The PAA should be specific enough that any regulator reading it understands exactly what is and is not authorized.
- Exceeding the 1:7 ratio. Physicians collaborating across multiple clinics can easily lose track of total FTE NPs across all agreements. Regular ratio audits prevent accidentally exceeding the limit.
- Inadequate alternate physician coverage. The PAA must designate one or more alternate physicians. When the primary physician is unavailable, someone must be available for supervision. Gaps in coverage leave the NP in a legally uncertain position.

Final Thoughts
Texas collaborating physician requirements exist to protect patients, not to create administrative burden. When the documentation is in order, the agreement reflects real practice, and the oversight is genuine, the arrangement works for everyone. Physicians who treat the PAA as a live, working document rather than a one-time task build defensible arrangements that hold up under scrutiny.
For physicians considering entering the Texas collaboration market, the compliance framework is manageable with the right structure. The key is getting the PAA right from the start, registering properly with the TMB, and building a documentation habit that keeps the quality assurance trail current.

Frequently Asked Questions
Does a Texas collaborating physician need to be physically present at the clinic?
No. Texas eliminated site-based prescriptive authority and does not require geographic proximity between the physician and the NP’s practice location. Remote collaboration is permitted. However, the physician must still provide adequate supervision, including monthly meetings, chart reviews, and real availability for clinical consultation.
How many NPs can one physician collaborate with in Texas?
Outside of hospital settings and medically underserved areas, one physician may supervise a maximum of seven full-time equivalent NPs and PAs combined. This cap applies across all non-exempt settings, so physicians collaborating with multiple clinics need to track their total FTE count across all arrangements.
How often does a Texas PAA need to be reviewed?
The Prescriptive Authority Agreement must be reviewed and re-signed at least once a year. Each annual review requires dated signatures from both the physician and the NP. The PAA must also be updated whenever the scope of practice changes, a new practice location is added, or the NP roster changes.
Does a Texas collaborating physician need to register with the TMB?
Yes. Under Texas Occupations Code §157.0511, physicians must register their prescriptive delegation relationships with the TMB through the Online Supervision and Prescriptive Delegation Registration System before the NP begins prescribing. Any changes to the delegation must be updated in the system within 30 days.
Can a Texas collaborating physician delegate Schedule II prescribing authority?
Schedule II prescribing requires more direct physician involvement and stricter documentation. The PAA must explicitly identify which controlled substances are authorized or excluded. If you do not intend to authorize Schedule II prescribing, that exclusion must be stated clearly in the agreement.
What happens if a Texas physician’s PAA is not compliant?
Both the physician and the NP can face disciplinary action from their respective boards. The TMB can investigate the physician’s delegation practices, and the TBON can act against the NP. Compliance failures can result in license restrictions, formal board orders, and in serious cases, license suspension. Maintaining current documentation is the most effective way to avoid regulatory exposure.
