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

AANP's May 2026 map puts Wyoming in its full-practice tier; the label is AANP's advocacy classification, not a legal category.

The legal fact behind it is the statute's own APRN definition: a nurse who may prescribe, administer, dispense or provide nonprescriptive and prescriptive medications, except Schedule I drugs, and who has responsibility for the direct care and management of patients.

A second statute, W.S.

33-21-158, provides that — except as otherwise provided by law, and including the definition's Schedule I restriction — an APRN acting within scope may fulfill any requirement for a physician's signature, certification, verification, affidavit or endorsement, and nothing in it expands scope.

Nothing in Title 33 inserts a physician between the PMHNP and that authority.

Title 33's transitional status for a new graduate is a temporary permit: issued pending the results of the first board approved national licensure or certification examination offered after graduation, not issued to anyone who previously failed that exam, surrendered on failure, its holder may practice only under the direction and supervision of a registered professional nurse, issued only one (1) time, and nonrenewable (W.S.

33-21-132(c), (e); its reserved title is G.A.P.R.N., W.S.

33-21-136(b)).

Whether a permit holder may prescribe is not stated.

No hours-or-years gate appears in Title 33.

The Board may also issue a one-time temporary permit of up to ninety (90) days to an APRN currently licensed in good standing in another jurisdiction, on a written application satisfactory to the board (W.S.

33-21-132(a), (b)).

The CE duty attaches to prescribers: licensees who have prescriptive authority owe three (3) hours of controlled-substance CE every two (2) years (W.S.

33-21-129(e), quoted below), and the Board regulates APRN qualifications by rule (W.S.

33-21-122(a)(xiv)) — rules not read.

The research section records no collaborative or supervisory agreement requirement in Wyoming statute, and Title 33 contains none: no physician signature to obtain before prescribing, no ratio capping how many APRNs one physician may back, no meeting or chart-review cadence, nothing filed with a medical board.

The statutory costs that do exist sit elsewhere: the licence itself, and — under W.S.

33-21-129(e) — the three (3) hours of controlled-substance CE every two (2) years for licensees with prescriptive authority.

Because the Board's rules were not read, ask the Board to confirm that no rule-level agreement condition applies.

The definition's only drug exclusion is Schedule I, as defined in W.S.

35-7-1013 and 35-7-1014; no Schedule II limit appears in Title 33.

Said plainly: as far as the statutes read, an outpatient Wyoming PMHNP can prescribe Schedule II ADHD stimulants.

Title 33 sets no quantity or day-supply rule of its own — but only Title 33 was read.

Title 35, the state's Controlled Substances Act, was cited here only for its Schedule I definitions, so quantity or registration rules in Title 35 are undisclosed; a separate state controlled-substance registration also stayed not located in the sources read.

Title 33 does attach one prescriber condition: the three (3) hours of controlled-substance CE every two (2) years for licensees with prescriptive authority (W.S.

33-21-129(e), quoted in the transition section).

A PMHNP registers with the DEA as a mid-level practitioner, and that registration covers only what state law allows — Title 33 allows every schedule except Schedule I, so Title 33 sets no cap for the DEA form's Schedules II–V listing to exceed; whether Title 35 adds one was not resolved, because it was not read.

Telehealth: the DEA and HHS telemedicine flexibilities run through December 31, 2026 under the Fourth Temporary Extension, removing the federal in-person-exam requirement for remotely prescribing controlled substances.

They lift no state limit, and Title 33 imposes no Schedule II cap to lift.

The permanent replacement is still only a proposed special-registration rule, so re-verify before relying on the flexibilities into 2027.

Wyoming has enacted the APRN Compact (W.S.

33-21-301/302), and the title statute already contemplates APRNs practicing in this state pursuant to the compact (W.S.

33-21-134(b)).

Wyoming's enacted text is an older form of the compact: its own entry clause, Article X(a), brings it into limited effect only when it has been enacted in ten (10) party states.

The seven-state figure circulates from the versions Delaware, North Dakota, South Dakota and Utah enacted; under either threshold the compact is not in effect, because five enactments are known as of September 2026 — so no multistate APRN licence exists anywhere today.

The session-law year of Wyoming's enactment was not captured, and the South Dakota Board of Nursing list updated March 30, 2026 naming only DE, ND, SD and UT leaves three possibilities: Wyoming's enactment post-dates the list, the list is stale, or the list reflects that Wyoming's text is a different version.

Until the compact takes effect, practise in Wyoming on a Wyoming licence; the RN-level Nurse Licensure Compact confers no nurse practitioner authority.

The one 2023-to-2026 change the sources capture is the APRN Compact enactment, whose session-law year was not captured in the sources read.

No amendment to the prescribing definition itself surfaced in Title 33, and the research section records no other recent change.

Because the enactment year is unrecorded and the March 2026 board list noted above leaves the timing and the version question open, check the Wyoming Legislature or the Board of Nursing for the enacting chapter before quoting either a year or a threshold.

Nothing in the sources read alters day-to-day prescribing for a Wyoming PMHNP.
