PMHNP Practice Requirements in Texas: Scope, Prescribing & Collaboration

Practice Authority

What is Texas NP practice authority?

On the American Association of Nurse Practitioners (AANP) State Practice Environment map, Texas is categorized as a restricted practice state. In practical terms, that means a nurse practitioner in Texas does not practice fully independently: state law requires delegated authority from a physician to perform the medical aspects of patient care, typically through a written agreement. PMHNPs are APRNs and fall under this framework.

Because your license and your authority to prescribe are governed by two different bodies, it is worth knowing who does what: the Texas Board of Nursing licenses and regulates APRNs, while physician delegation is also addressed by the Texas Medical Board. For your specific obligations, always verify with the Texas Board of Nursing and the current text of the Texas Occupations Code rather than relying on any summary.

Collaboration & Agreements

Is a physician agreement required in Texas?

Generally, yes. Texas law provides for a prescriptive authority agreement (PAA), a written agreement through which a physician delegates prescribing authority to an APRN or physician assistant. In broad terms, a PAA is written, signed, and dated by the parties; identifies the parties and their license numbers; describes the practice setting; and identifies the categories of drugs or devices that may or may not be prescribed. The agreement is meant to be tailored to the specific practice relationship.

These agreements carry ongoing compliance duties, and the details, including any required meetings, chart review, or quality-assurance provisions, are set by statute and rule and can change. Do not treat any template as authoritative. Confirm the current PAA requirements, and how to register your delegating physician, with the Texas Board of Nursing.

Prescribing

Prescriptive authority and controlled substances

With a valid prescriptive authority agreement in place, Texas APRNs may prescribe within the categories the delegating physician has authorized. Controlled-substance prescribing is more tightly governed: it depends on the terms of the agreement, applicable state limits, and federal DEA registration. For PMHNPs, whose formularies frequently include controlled substances such as stimulants and certain anxiolytics, the specific limits and any restrictions on Schedule II prescribing are exactly the kind of detail you must verify against current law and Board guidance rather than assume.

We do not list statute numbers, day-supply limits, or physician-count caps here because those figures change; for any hard number, confirm with the Texas Board of Nursing, the Texas Medical Board, and the DEA. If a claim about your prescribing authority cannot be confirmed there, treat it as unverified.

Billing & Credentialing

What this means for your billing and credentialing

Texas restricted-practice rules shape more than clinical workflow; they shape how you get paid. Payers want to see a compliant delegation or prescriptive authority relationship on file, and your CAQH profile, group enrollments, and payer applications should reflect your APRN licensure, DEA registration, and supervising or collaborating physician arrangement accurately. Mismatches between what your agreement says and what your enrollment says are a common cause of denials and delayed effective dates.
