California Standardized Procedure for Registered Nurses

Recognized but not required in every case. The Standardized Procedure is the written instrument California law names for a Registered Nurse working with a physician. Below: the board that governs it, what it contains when one is used, and the supervision rules that apply either way.

FULL for general nursing scope (Bus. & Prof. Code §2725) — no physician-supervision requirement for baseline RN practice. SUPERVISED_ONLY carve-out for medical-aesthetic delegation (Botox/fillers/laser): treated as a delegated medical act, not baseline RN scope, per Medical Board of California guidance and 16 CCR §1364.50.

What a voluntary Registered Nurse agreement covers in California

California requires no written agreement for registered nurses. These are the clauses a practice includes when it chooses to put one in writing. The California Board of Registered Nursing governs registered nurses here.

  1. A standardized procedure used by Registered Nurse is a policy and protocol developed by a licensed health facility or an organized health care system through collaboration among administrators and health professionals, including physicians and nurses.

  2. The Standardized Procedure also carries 1 scope clauses, authored in the document itself.

Statutes and rules these clauses cite

  1. Cal. Bus. & Prof. Code § 2725statute

    Defines the practice of registered nursing, including medication administration, immunization techniques and implementation of standardized procedures; subdivision (c) defines standardized procedures as policies and protocols developed by a licensed health facility or organized health care system through collaboration among administrators and health professionals including physicians and nurses.

What California does require

The supervision and prescribing rules that apply to registered nurses regardless of any agreement.

Proximity

physician-delegated elective cosmetic procedure using a laser or intense pulsed light device: Available remotely (no on-site requirement)

16 CCR §1364.50 (confirmed verbatim via direct fetch): the delegating physician need not be on-site but must be 'immediately available' — defined as 'contactable by electronic or telephonic means without delay, interruptible, and able to furnish appropriate assistance and direction throughout the performance of the procedure.' The regulation says 'licensed health care provider' generically rather than naming RNs by profession, though MBC's own Medical Spas guidance describes this standard as applying to RN-performed procedures.

Prescriptive authority

No agreement needed to prescribe · no controlled-substance authority

Confirmed: general RNs (non-APRN) have no independent prescriptive authority — §2725 ties medication administration to orders from a physician, dentist, podiatrist, or clinical psychologist.

Written agreement

Not required

Unconditional for general nursing practice. For medical-aesthetic delegation, a written delegation order/standardized procedure from a supervising physician is required — legal hook is 16 CCR §1474 (general standardized-procedure content rules) plus §1364.50 (physician-availability standard specific to laser/IPL). The Medical Board's own 'Medical Spas' guidance page confirms: medical-scope procedures 'must be owned by physicians,' and qualified personnel are limited to physicians, RNs under physician supervision, and PAs under physician supervision.

Practice ownership (corporate practice of medicine)

Licensee-only ownership required — An RN CANNOT own the medical-scope portion of a med-spa business outright (Bus. & Prof. Code §2400). Corp. Code §13401.5(a), CONFIRMED via direct fetch, allows RNs (among 15 listed allied professions) to hold shares in a MEDICAL professional corporation as a minority (≤49%) shareholder, capped further at not exceeding the number of physician shareholders — distinct from an RN wholly owning their OWN nursing-scope entity (fine for nursing services, not for medical services like injectables).

Corp. Code §13401.5(a)'s RN-inclusion and percentage structure are confirmed via a dedicated follow-up fetch, superseding the original secondary-sourced hedge (an early fetch attempt had incorrectly suggested RNs were absent from the list; two later, independent fetches confirmed they are included).

About California's rules

California's NPs reach genuine full independence (AB 890/SB 1451, ~6 years total) and CNMs need zero physician involvement for definitionally 'low-risk' pregnancy care — no hours threshold. NPs/PAs may also majority-own their own practice corporations (Corp. Code §13401.5), cutting against the assumption that CA's strict, actively-enforced CPOM regime (2026 AG settlements against Carbon Health, Aspen Dental) blocks all non-physician ownership. CRNA is order-based, not supervision-based. Esthetician laser use is a flat criminal misdemeanor — no delegation pathway exists.
