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

AANP's May 2026 map puts Colorado in its full practice tier.

The legal fact behind the label is the Board of Nursing's own definition: independent practice is APRN practice for which the APRN is solely responsible and performs on their own initiative, in a setting where none of the rule's insurance exemptions applies.

Rule 1.14(E) — implementing § 12-255-113 — requires an APRN in independent practice to carry professional liability insurance of not less than five hundred thousand dollars per claim, with a one-million-five-hundred-thousand-dollar annual aggregate; its exemptions cover federal or military practice, employer-provided coverage at the statutory amounts, uncompensated care and public employees.

Every APRN must also practise to national professional-organization standards and maintain a safe mechanism for consultation or collaboration with a physician or, when appropriate, referral — a professional standard, not a delegating agreement.

An application evidences six statutory conditions: a graduate degree, controlled-substance and prescription-drug education, national certification unless excepted, liability insurance, registry listing and a signed attestation of at least three years of combined clinical work experience as a professional nurse or APRN.

Rule 1.15(F)(1) adds pathophysiology, pharmacology and physical-assessment coursework, a licence in good standing, and a mentor attestation — the mentor is named at the provisional application.

Paid, unpaid, volunteer and student work counts toward the three years; gratuitous care of friends or family does not.

The result: provisional prescriptive authority, already authorizing Schedules II through V within the role and population focus; full authority takes seven hundred fifty mentored hours within three years, or provisional authority expires.

Movers with prescriptive authority in another state or U.S. jurisdiction — military credentials deemed equivalent — who verify at least 750 prescribing hours and attest to the same three years apply directly for full authority, hours at the Board's sole discretion; with fewer, they seek provisional authority under the standard requirements and complete the balance in a Colorado mentorship within three years.

The only relationship the rules require is the prescribing mentorship, and it ends; no ongoing collaborative agreement appears in the statutes and rules read.

Before it begins, the RXN-P submits the plan to the Board of Nursing, not to a medical board, so the Board can judge whether the mentorship is sufficiently structured for the role and population focus.

The Mentorship Agreement is written, signed by the mentor and the RXN-P, and retained for three years after completion.

The mentor can be a physician or an APRN who already holds full prescriptive authority in Colorado; both must have an unrestricted DEA registration, a licence without disciplinary sanction, and an active Colorado practice corresponding with the RXN-P's role and population focus.

Remote mentoring counts if synchronous, and email does not count; if the mentor retires, falls ill or relocates mid-mentorship, any hours accrued without a mentor do not count toward the 750.

From the moment provisional prescriptive authority is granted, Rule 1.15 authorizes prescribing controlled substances Schedules II through V, and the RXN-P or RXN must hold a valid DEA registration alongside it.

No psychiatric or stimulant-specific limit appears in the statutes and rules read, so a Colorado PMHNP with prescriptive authority can prescribe Schedule II ADHD stimulants within the role-and-population-focus rule.

The statute points to outside law in two places: § 12-255-112(6) subjects prescribers to the prescription limitations in § 12-30-109, and § 12-255-112(8) requires all prescriptions to comply with applicable federal and state law, including the pharmacy act and Colorado's controlled-substance statutes; none of those provisions was read, so confirm their terms with the Board.

The federal layer adds nothing beyond state law: a DEA registration covers only what Colorado allows, and the DEA and HHS telemedicine flexibilities, in force through December 31, 2026 and extendable only by a fifth extension or a final special-registration rule, lift no Colorado limit.

No separate state controlled-substance registration was located in the sources read.

The APRN registration alone does not authorize prescribing; the Board must grant prescriptive authority as a separate application.

Prescriptive authority reaches only patients appropriate to the APRN's scope of practice, and prescribing outside it, or for other than a therapeutic purpose, can cost the authority and bring discipline.

Dispensing and distribution are excluded except, per Rule 1.15(I)(3), receiving and distributing a therapeutic regimen of prepackaged drugs prepared by a licensed pharmacist or an FDA-registered drug manufacturer and appropriately labeled, free samples supplied by a drug manufacturer, and distributing drugs for administration and use by other individuals as authorized by law.

None of the gating depends on a physician's sign-off: the consultation-and-referral duty is the professional-standard layer, and the prescribing gate is the Board's own grant.

Colorado has not enacted the APRN Compact.

The compact takes effect only once seven states enact it, and as of September 2026 five had (Delaware, North Dakota, South Dakota, Utah and Wyoming), so no APRN holds a multistate APRN licence today.

The Nurse Licensure Compact is an RN compact and gives no nurse practitioner authority, though it matters practically: Colorado's prescriptive-authority rules build reinstatement and renewal on an active Colorado or multi-state compact RN licence.

To practise as a PMHNP in Colorado you need Colorado APRN registration and Colorado prescriptive authority.

The sources read show revision activity inside the 2023-2026 window but do not describe its content: Rule 1.14's footer records a revision effective December 15, 2023, and the chapter's register notes list further revisions effective December 15, 2024 and June 14, 2025 — Rule 1.15's own footer ends at December 30, 2021, so those register entries look chapter-level rather than rule-specific.

The saved CRS text is the 2024 edition, and 2025-2026 session laws were not checked, so confirm with the Board of Nursing before assuming the rules are unchanged.
