PMHNP Practice Authority in California: Independence, Physician Agreements and Schedule II

AANP's May 2026 map puts California in its restricted tier.

The label is AANP's advocacy classification; the legal default is BPC § 2836.1 — a nurse practitioner furnishes drugs under a standardized procedure developed and approved by the supervising physician and surgeon, the nurse practitioner and the facility administrator, with physician supervision that need not be physically present but requires telephonic availability at the time of patient examination.

AB 890 added the two exit tiers: a 103 NP practises without standardized procedures inside listed physician settings, and a 104 NP practises outside them.

Neither rung is automatic; both rest on years of qualifying practice.

Section 2837.103(a)(1)(D) requires three full-time equivalent years of practice or 4600 hours of transition to practice in California; an NP who has been practising as a nurse practitioner in direct patient care for that amount within the last five years may be deemed to satisfy it.

The attestation goes to the board, signed by a licensed physician and surgeon, a 103 NP or a 104 NP; the attester need not specialize in the applicant's § 2836 category, vouches only for completion, not competence, and carries no liability unless produced fraudulently.

The board issues the 104 certificate under § 2837.104(b) to an NP who meets every § 2837.103(a)(1) requirement, holds a valid and active California RN licence plus a master's degree in nursing or a related clinical field or a doctoral degree in nursing, and has practised three more years in good standing beyond the transition — lowered at the board's discretion for a Doctorate of Nursing Practice holder.

Two gaps: § 2837.101's transition-to-practice definition was not retrieved from leginfo (a 503); no calendar date for the first 104 certificates.

On the default path § 2836.1 caps the ratio: no physician and surgeon shall supervise more than four nurse practitioners at one time.

What replaces physician supervision differs by rung.

For a 103 NP it is the setting: § 2837.103(a)(2) allows the (c) functions only in listed settings where one or more physicians and surgeons practise with the NP — clinics, health facilities excluding correctional treatment centers and state hospitals, the facilities described in Health and Safety Code Chapter 2.5 (commencing with Section 1440), medical group practices, home health agencies and hospice facilities.

A 104 NP practises outside them, consulting and collaborating with other healing arts providers; physician consultation is obtained as specified in the individual protocols and required for emergent conditions after stabilizing care has started, problems not resolving as anticipated, history, physical or lab findings inconsistent with the clinical perspective, or patient request, and a referral plan with specific criteria is mandatory.

Both must tell every new patient, in language the patient understands, that a nurse practitioner is not a physician and surgeon.

Section 2837.103(c)(4)(B) authorizes a 103 or 104 NP to prescribe, administer, dispense and furnish pharmacological agents including controlled substances, and no Schedule II limit appears in §§ 2837.103 or 2837.104 as read — so nothing in the sections read bars outpatient Schedule II stimulant prescribing on that path.

On the default standardized-procedure path the rule is narrower: furnishing may include Schedules II through V within the drugs the standardized procedure names, and Schedule II or III furnishing must follow a patient-specific protocol approved by the treating or supervising physician, with the Schedule II protocol addressing the diagnosis.

An NP certified by the board who holds an active furnishing number, is authorized through standardized procedures to furnish Schedule II, and is registered with the DEA must also complete a Schedule II continuing-education course covering the risks of addiction.

A separate state controlled-substance registration was not located in the sources read.

Federally, the DEA registration covers only what California allows, and the telemedicine flexibilities running through December 31, 2026 lift none of these limits.

Without standardized procedures, a 103 or 104 NP may conduct advanced assessments; order, perform and interpret diagnostic procedures; establish primary and differential diagnoses; and prescribe, order, administer, dispense, procure and furnish therapeutic measures including pharmacological agents, plus delegate tasks to medical assistants.

The practice must stay within the NP's education, training and national certification — the 104 section says so expressly — and when a patient's condition is beyond the NP's education and training, the NP must refer to a physician and surgeon or other licensed provider.

The practice also posts a conspicuous notice that the Board of Registered Nursing regulates it, with the board's telephone number and the site where the licence can be checked.

The sections read name no separate psychiatric credential: a PMHNP performs the same (c) functions, bounded by education, training and national certification.

California has not enacted the APRN Compact; it is not among the five enacting states found (Delaware, North Dakota, South Dakota, Utah and Wyoming).

The compact comes into effect only when seven states enact it, so no APRN holds a multistate APRN licence today.

The Nurse Licensure Compact is an RN compact and gives no nurse practitioner authority in another state.

To practise in California you need BRN licensure on California's own terms — the 104 certificate expressly requires a valid and active California RN license plus a master's degree in nursing or a related clinical field, or a doctoral nursing degree (BPC § 2837.104(b)(2)).

Article 8.5, the article that holds both AB 890 tiers, was added by Stats.

2020, chapter 265, and the 104 pathway has been operative since January 1, 2023.

Both §§ 2837.103 and 2837.104 were then amended by Stats.

2024, chapter 481 (SB 1451), effective January 1, 2025.

The standardized-procedure default in § 2836.1 is older: it was last amended by Stats.

2018, chapter 693 (SB 1109), effective January 1, 2019.

One dated trap: the statute does not state when the first 104 certificates issued, so do not assume any 2026 issuance date without a Board of Registered Nursing source.

A 103 NP must carry professional liability insurance appropriate for the practice setting, and the 104 section imposes the same duty.

Any health care setting operated by the Department of Corrections and Rehabilitation is exempt from § 2837.103; the 104 section as read carries no parallel exemption.

On the other side, subject to the liability-insurance duty in subdivision (g) and the bylaws' conflict-of-interest policies, a 104 NP is eligible for organized medical staff membership under § 2837.104(a)(2) and, as a member, may vote at meetings of the department to which nurse practitioners are assigned under (a)(3).

The 104 section's corporate-practice sentence is blunt — corporations and other artificial legal entities have no professional rights, privileges or powers — but subdivision (i) lifts it where the certificate is inactive, surrendered, revoked or otherwise restricted by the board, or the NP is employed pursuant to the exemptions under Section 2401.
