Can a Certified Registered Nurse Anesthetist administer anesthesia in NC without a physician's supervision?

Plain-English summary

Senator James Forrester asked the AG whether NC's Nursing Practice Act allows Certified Registered Nurse Anesthetists (CRNAs) to practice anesthesia without physician supervision. The question matters for surgical centers, dental offices, and rural hospitals trying to staff anesthesia coverage in a market where there aren't always enough anesthesiologists.

Senior Deputy AG Ann Reed and Special Deputy AG Gayl Manthei answered: physician supervision is required for CRNA-administered anesthesia, with one carve-out for dental anesthesia.

The analysis rested on the Nursing Practice Act's definition of "practice by a registered nurse" in G.S. 90-171.20(7). The Act lists nine components of nursing practice. Component (e) is the central one: a registered nurse can "collaborate with other health care providers in determining the appropriate health care for a patient but, subject to the provisions of G.S. 90-18.2, not prescribing a medical treatment regimen or making a medical diagnosis, except under the supervision of a licensed physician." So the Nursing Practice Act itself bars nurses from prescribing or diagnosing without physician supervision.

The Board of Nursing's CRNA rules (21 NCAC 36.0226) follow the statute. The rules list permitted CRNA activities (selecting preanesthetic medication, selecting anesthesia modalities, recognizing abnormal findings, managing fluid/blood/electrolyte/acid-base balance) but require that a CRNA "may not prescribe a medical treatment regimen or make a medical diagnosis except under the supervision of a licensed physician."

The AG's key step is the conclusion that anesthesia management is prescribing and diagnosing. "Management of a patient's anesthesia requires the prescription of medical treatment regimens and the making of medical diagnoses." Selecting which agent, how much, when to adjust, when to intervene for adverse responses, all involve prescribing and diagnosing. So even though CRNA rules permit a CRNA to perform these tasks, the Nursing Practice Act's physician-supervision requirement runs through them.

The dental exception. G.S. 90-30.1 authorizes dentists to use anesthesia or sedation in their practices pursuant to rules promulgated by the Board of Dental Examiners. A dentist who is himself authorized to administer anesthetics may be assisted by others, including CRNAs. The dentist's own authority covers the anesthesia administration, so the assisting CRNA doesn't need separate physician supervision. This is the only carve-out the opinion identifies.

The practical implication: CRNA practice in NC required physician supervision except in dental settings where an authorized dentist directs the anesthesia. Rural hospitals and standalone surgical centers using CRNAs needed an anesthesiologist (or, depending on the facility's structure, another physician) supervising the CRNA's anesthesia work.

Currency note

This opinion was issued in 1998. Subsequent statutory amendments, court decisions, or later AG opinions may have changed the analysis. Treat this page as historical context, not current legal advice. Verify current law before relying on any specific rule, deadline, or remedy mentioned here.

CRNA scope of practice has been intensely litigated and lobbied since 1998. Federal Medicare rules permit states to "opt out" of physician-supervision requirements, and many have. Several lawsuits and rule changes have refined CRNA practice rules in NC since this opinion. Any current question about CRNA supervision in NC should consult current Nursing Practice Act provisions (G.S. 90-171.20 et seq.), current 21 NCAC 36.0226 rules, and current Medicare conditions of participation rules for the relevant facility type.

Common questions

Q: What is a CRNA?
A: A Certified Registered Nurse Anesthetist. A registered nurse with additional graduate-level training in anesthesia. CRNAs administer all types of anesthesia (general, regional, local, sedation) but must do so within the scope-of-practice limits set by state law.

Q: Why does the Nursing Practice Act require physician supervision for prescribing?
A: To preserve the physician-nurse practice distinction. Nurses care for patients; physicians prescribe treatment and make diagnoses. The Nursing Practice Act lets nurses do many things, including some that overlap with physician duties, but only under physician supervision when prescribing or diagnosing is involved.

Q: Why does anesthesia count as "prescribing"?
A: Because choosing an anesthetic agent, dose, route, and timing is a prescription. Reading the patient's vitals and deciding whether to add a vasopressor, deepen sedation, or reverse the agent is diagnosing and prescribing in real time. The AG concluded that anesthesia management is inherently a prescribing-and-diagnosing activity.

Q: What is G.S. 90-30.1?
A: A statute giving dentists statutory authority to administer or supervise the administration of anesthesia and sedation in dental practice, subject to Board of Dental Examiners rules. The statute treats dentists as authorized providers for anesthesia in their practice.

Q: Can a CRNA assist a dentist?
A: Yes, under G.S. 90-30.1. A dentist who is authorized to administer anesthetics may be assisted by others, including CRNAs. The dentist's own authority covers the situation; the CRNA is assisting under the dentist's supervision.

Q: What is the supervising physician's responsibility?
A: General supervision and availability, not necessarily continuous physical presence. The Board of Nursing's CRNA rules at 21 NCAC 36.0226 spell out the supervision requirements. Practically, anesthesiologists often supervise multiple CRNAs simultaneously.

Background and statutory framework

NC's Nursing Practice Act (Article 9A of Chapter 90) regulates the practice of nursing. It defines what registered nurses can and cannot do without physician oversight. G.S. 90-171.20(7) is the central definitional provision, listing nine components of nursing practice with the prescribing-and-diagnosing limit running through component (e).

The Board of Nursing, like other licensing boards, has rulemaking authority. The Board's CRNA rules (21 NCAC 36.0226) detail the specific activities CRNAs may perform. The rules track the statutory limit: CRNAs cannot prescribe or diagnose without physician supervision.

Anesthesia is the central use-case for the CRNA category. CRNAs are trained specifically to deliver anesthesia, and their employment in hospitals, surgical centers, and (in this opinion's context) dental practices is widespread. The supervision question is essentially the question of how independently CRNAs can practice.

NC's answer in 1998 was "not independently, except in dental practice." The exception in G.S. 90-30.1 reflects the practical reality of dental anesthesia: dentists administer or supervise anesthesia in dental practice as part of routine treatment, and the legislature has explicitly given them authority to do so. A CRNA assisting an authorized dentist falls within that statutory framework, so no additional physician supervisor is needed for that setting.

This framework places NC closer to the more conservative end of the CRNA-scope-of-practice spectrum nationally. Other states permit fully independent CRNA practice without physician supervision; NC requires it. Federal Medicare opt-out provisions (added in 2001) let states choose to forgo the supervision requirement for Medicare reimbursement purposes, but NC has not opted out.

Original opinion text

[Excerpting the body of the opinion as preserved by the Sofya conversion. The opening date/addressee block was lost during markdown conversion.]

(7) The "practice by a registered nurse" consists of the following nine components:

a. Assessing the patient's physical and mental health including the patient's reaction to illnesses and treatment regimens;

b. Recording and reporting the results of the nursing assessment;

c. Planning, initiating, delivering and evaluating appropriate nursing acts;

d. Teaching, delegating to or supervising other personnel in implementing the treatment regimen;

e. Collaborating with other health care providers in determining the appropriate health care for a patient but, subject to the provisions of G.S. 90-18.2, not prescribing a medical treatment regimen or making a medical diagnosis, except under the supervision of a licensed physician;

f. Implementing the treatment and pharmaceutical regimen prescribed by any person authorized by State law to prescribe such a regimen;

g. Providing teaching and counseling about the patient's health care;

h. Reporting and recording the plan for care, nursing care given, and the patient's response to that care; and

I. Supervising, teaching and evaluating those who perform or are preparing to perform nursing functions and administering nursing programs and nursing services. [Emphasis added.]

The Nursing Practice Act prohibits the prescribing of a medical treatment regimen or the making of a medical diagnosis by a nurse, except under the supervision of a licensed physician, and allows the implementing of the treatment and pharmaceutical regimes only when prescribed by others with legal authority.

The Board of Nursing has promulgated rules governing CRNA anesthesia care (21 NCAC 36.0226) (the "CRNA rules"). The CRNA rules delineate the qualifications that a CRNA must meet in order to engage in nurse anesthesia practice (21 NCAC 36.0226(b)) and define the activities constituting nurse anesthesia practice that only a CRNA may perform (21 NCAC 36.0226(c)). Among those activities are such things as selecting preanesthetic medication; selecting general and regional anesthesia modalities consistent with the client's need; recognizing abnormal findings and implementing corrective action; and managing the client's fluid, blood, electrolyte and acid-base balance.

While the list of permitted activities is broad, those activities are limited by a requirement that a CRNA "may not prescribe a medical treatment regimen or make a medical diagnosis except under the supervision of a licensed physician." (21 NCAC 36.0226(b)(1)). Management of a patients' anesthesia requires the prescription of medical treatment regimens and the making of medical diagnoses. The CRNA rules, therefore, do not eliminate the requirement that the anesthesia care of a patient be under the supervision of a physician.

An exception to the requirement that a CRNA be supervised by a physician is provided by N.C.G.S. § 90-30.1, which authorizes dentists to use anesthesia or sedation in their practices pursuant to rules promulgated by the Board of Dental Examiners. A dentist who is himself authorized to administer anesthetics may be assisted by others, including CRNAs.
