Colorado collaborating physician requirements apply to a full-practice-authority state with a specific transitional prescribing mentorship period during which physicians play a defined and important role. Colorado APRNs may practice independently without any physician collaboration agreement. However, before an APRN may exercise full prescriptive authority for medications and controlled substances, the APRN must complete a structured prescribing mentorship of 750 hours under the supervision of either a physician or an APRN who already holds full prescriptive authority.
For physicians in Colorado, the relevant framework is the prescribing mentorship structure governed by Colorado Revised Statutes § 12-255-112 and Colorado Board of Nursing Rules Chapter 15. This is not a traditional collaborative practice agreement. It is a documented, structured prescribing mentorship tied to the APRN’s pathway from provisional to full prescriptive authority. This guide covers both the full practice authority context and what the prescribing mentorship requires of physicians in 2026.
Colorado Collaborating Physician Overview: Where Colorado Stands
Colorado is a full-practice-authority state for APRNs. The Colorado Supreme Court upheld the Board of Nursing’s authority to recognize APRNs as independent providers in a 2015 decision that confirmed APRNs do not require physician supervision or a collaborative agreement for practice. Colorado APRNs are recognized as primary care providers under state law and policy.
Governing Bodies
Two regulatory bodies govern healthcare practice in Colorado:
- Colorado Board of Nursing: Governs APRN licensure, inclusion on the Advanced Practice Registry (APR), prescriptive authority pathways, prescribing mentorship requirements, and disciplinary matters under Colorado Revised Statutes § 12-255-111, § 12-255-112, and Colorado Board of Nursing Rules.
- Colorado Board of Medical Examiners (now the Colorado Medical Board): Governs physician licensure and disciplinary matters. Physician preceptors and mentors in APRN prescribing mentorships are subject to their own board’s oversight standards.
The Advanced Practice Registry
Colorado does not use a traditional APRN license. Instead, APRNs are included on the Advanced Practice Registry (APR) maintained by the Board of Nursing after meeting qualifications including graduate education, national certification, and professional liability insurance. Prescriptive authority is a separate designation applied for through a specific pathway under CRS § 12-255-112.
Full Practice Authority in Colorado: What It Means for Physicians
Colorado APRNs with full prescriptive authority (designated as RXN on the APR) may independently:
- Diagnose and treat patients without physician oversight
- Prescribe legend drugs and pharmacologic treatments
- Prescribe Schedule II through V controlled substances with a valid DEA registration
- Open and operate independent practices
- Practice in any setting consistent with their specialty and population focus
No physician collaboration agreement is required for any of these activities. An APRN with full prescriptive authority in Colorado needs no physician agreement, protocol, or oversight structure under state law.
Collaboration as a Professional Standard
Colorado’s APRN regulatory framework includes an Articulated Plan requirement that expects APRNs to describe their ongoing collaborative relationships with physicians and other health care professionals as part of their prescribing approach. This is a professional documentation expectation built into the prescribing mentorship pathway, not an ongoing agreement requirement that continues after full prescriptive authority is granted.
The Prescribing Mentorship: Where Physician Involvement Still Applies
The Colorado prescribing mentorship is the primary structured context in which a physician’s involvement in an APRN’s practice is active, documented, and legally defined. The mentorship is not a traditional collaboration agreement. It is a supervised prescribing period that bridges provisional prescriptive authority and full prescriptive authority.
The Two-Stage Prescriptive Authority Pathway
Colorado’s prescriptive authority pathway moves through two stages:
Stage 1: Provisional Prescriptive Authority (RXN-P)
The APRN receives provisional prescriptive authority from the Colorado Board of Nursing after meeting initial requirements including graduate education, pharmacology coursework, national certification, APR inclusion, professional liability insurance, and an attestation of at least three years of combined clinical work experience as a professional nurse or APRN under CRS § 12-255-112.
Stage 2: Full Prescriptive Authority (RXN)
The APRN advances from provisional to full prescriptive authority by completing 750 hours of a documented prescribing mentorship with an approved preceptor and developing an Articulated Plan for safe prescribing. The mentorship must be completed within three years of receiving provisional authority.
Provisional Prescriptive Authority: How NPs Get to the Mentorship Stage
Before the physician’s mentorship role begins, the APRN must meet several threshold requirements to obtain provisional prescriptive authority. These are APRN obligations, but physicians considering a mentorship role should understand the stage at which the physician’s involvement begins.
Under CRS § 12-255-112(1), the requirements for provisional prescriptive authority include:
1. Graduate Degree
An appropriate graduate degree as determined by the Colorado Board of Nursing.
2. Educational Requirements in Controlled Substances
Satisfactory completion of specific educational requirements in the use of controlled substances and prescription drugs, either as part of the degree program or in addition to it.
3. National Certification
Certification from a nationally recognized accrediting agency as defined by board rule, unless the board grants an exception.
4. Professional Liability Insurance
Coverage as required by CRS § 12-255-113.
5. Advanced Practice Registry Inclusion
Inclusion on the APR pursuant to CRS § 12-255-111.
6. Three-Year Clinical Experience Attestation
A signed attestation stating that the APRN has completed at least three years of combined clinical work experience as a professional nurse or as an APRN in the same role and population focus as the prescriptive authority being sought.
The 750-Hour Prescribing Mentorship: What Physicians Must Do
Once the APRN holds provisional prescriptive authority (RXN-P), the mentorship period begins. The mentorship is the structured prescribing experience through which the APRN advances to full prescriptive authority (RXN).
The 750-Hour Requirement
Under Colorado Board of Nursing Rules Chapter 15 and CRS § 12-255-112, the APRN must complete 750 hours of documented prescribing experience in a mutually structured prescribing mentorship. These 750 hours are mentorship hours specifically tied to prescribing, not general clinical practice hours.
The Physician’s Role: Preceptor vs. Mentor
Colorado’s mentorship framework uses two terms for the physician’s role depending on the phase:
- Physician Preceptor: The physician who supervises the APRN during the initial prescribing mentorship period. The preceptor must provide oversight of the APRN’s prescribing, review prescribing decisions, and guide the development of the APRN’s safe prescribing practices.
- Physician Mentor: The physician who may serve in an ongoing consultative and guidance role as the APRN approaches and achieves full prescriptive authority.
The physician must hold a current, active Colorado medical license without disciplinary sanctions. A current restriction, limitation, or condition on the physician preceptor’s or physician mentor’s medical license, including confidential participation in a peer health assistance or alternative to discipline program, disqualifies the physician from serving in the preceptor or mentor role.
What the Physician Does During the Mentorship
During the 750-hour mentorship, the physician preceptor:
- Provides oversight of the APRN’s prescribing decisions within the APRN’s specialty and population focus
- Reviews prescriptions and prescribing patterns with the APRN
- Participates in developing the Articulated Plan for safe prescribing
- Maintains documentation of the mentorship hours completed
- Provides guidance on safe prescribing practices and appropriate clinical judgment in prescribing
The Mentorship Can Be With a Physician or an Experienced APRN
A key feature of Colorado’s framework that distinguishes it from traditional physician collaboration states is that the preceptor or mentor does not have to be a physician. The 750-hour mentorship may be completed under the supervision of either a physician or an APRN who holds full prescriptive authority (RXN designation on the APR) in the same or comparable role and population focus. This flexibility means physicians are one of two qualifying mentor types, not the exclusive option.
The Articulated Plan: Required Documentation for Every Mentorship
The Articulated Plan is a written document that is a mandatory component of every Colorado prescribing mentorship. It is not a general collaboration agreement. It is a specific planning document developed jointly by the APRN and their preceptor or mentor.
What the Articulated Plan Must Include
Under Colorado Board of Nursing Rules Chapter 15, the Articulated Plan must:
- Include a strategy for safe prescribing within the APRN’s role and population focus
- Outline how the APRN intends to maintain ongoing collaboration with physicians and other health care professionals in connection with the APRN’s practice of prescribing medications
- Address how the APRN will recognize and respond to clinical situations that require physician consultation or referral when prescribing
The Articulated Plan After Full Authority
The Articulated Plan describes the APRN’s ongoing collaborative relationships with physicians and other health care providers. After the 750-hour mentorship is completed and full prescriptive authority is granted, the Articulated Plan serves as a record of the APRN’s professional commitment to appropriate prescribing collaboration. It is not a legally binding ongoing collaboration agreement in the manner of restricted-practice states.
Who Qualifies as a Physician Preceptor or Physician Mentor in Colorado
A qualifying Colorado physician preceptor or mentor must:
- Hold a current, active Colorado medical license (MD or DO)
- Practice in a specialty or clinical area relevant to the APRN’s role and population focus
- Have no current disciplinary sanctions, restrictions, limitations, or conditions on their medical license, including confidential participation in peer health assistance or alternative to discipline programs
The Population Focus Alignment Expectation
The mentorship must occur within the APRN’s role and population focus as identified on the APR. A physician whose clinical practice is relevant to the APRN’s population focus provides the most clinically meaningful mentorship. A family medicine or internal medicine physician can meaningfully mentor an NP in a family health or adult gerontology focus. A psychiatrist or mental health physician is the appropriate preceptor for a psychiatric NP’s prescribing mentorship.
No Geographic Proximity Requirement
Colorado does not impose a geographic proximity requirement on physician preceptors or mentors. The mentorship may occur in person, by telemedicine, or through structured remote engagement. The physician and APRN must be able to genuinely engage in the oversight and review of prescribing decisions, but physical co-location is not mandated.
The Three-Year Completion Window
Under CRS § 12-255-112 and Colorado Board of Nursing Rules, the prescribing mentorship must be completed within three years of the APRN receiving provisional prescriptive authority.
What Happens If the Window Is Not Met
If the APRN does not complete the 750-hour mentorship within three years of receiving provisional prescriptive authority, the APRN cannot advance to full prescriptive authority (RXN). The APRN would need to address the incomplete mentorship with the Colorado Board of Nursing before full authority can be granted.
Implications for Physicians
Physicians entering prescribing mentorship arrangements in Colorado should understand that the APRN has a defined three-year window to complete the hours. A physician who begins a mentorship relationship and then becomes unavailable before the APRN completes the 750 hours creates a practical barrier to the APRN’s advancement. Physicians should plan mentorship commitments with the full duration of the engagement in mind.
Prescriptive Authority and Controlled Substances in Colorado
Colorado APRNs with full prescriptive authority (RXN) may prescribe Schedule II through V controlled substances independently with a valid DEA registration and compliance with DEA requirements. No physician involvement of any kind is required for controlled substance prescribing by fully authorized APRNs.
Prescribing Limits for APRNs Under CRS § 12-255-112(6)
Colorado places specific limits on opioid prescribing that apply to APRNs. Prescribing must remain within the APRN’s specialty and population focus. APRNs with prescriptive authority must complete at least two hours of training per renewal cycle in safe opioid prescribing or substance use prevention under CRS § 12-255-111 and Board Rule 1.20.
Documentation Retention
All Colorado nurses, including APRNs, must maintain documentation of their professional development and continuing education activities for at least four years in case of a Board audit. The Board conducts random audits and does not require submission of documentation at renewal, but documentation must be available.
Where Physician Collaboration Also Applies: The PA Framework
Physician assistants in Colorado are not covered by the APRN full practice authority framework. PAs must practice under a physician collaboration structure governed by the Colorado Physician Assistant Licensing Act and the Colorado Medical Practice Act.
Colorado PA Collaboration Requirements
Colorado PAs must have a formal relationship with a collaborating physician. The specific structure of that relationship is determined by the practice setting, and the degree of supervision required depends on the PA’s experience and the clinical context. Physicians who serve as collaborating physicians for Colorado PAs should verify current requirements with the Colorado Medical Board, as PA collaboration rules are maintained separately from the APRN framework addressed in this guide.
Common Compliance Considerations for Colorado Physician Preceptors and Mentors
Most Colorado prescribing mentorship compliance issues involve documentation gaps, incomplete hour tracking, and preceptor eligibility.
- Disciplinary status not confirmed before serving as preceptor. A physician with any current restriction, limitation, or condition on their license cannot serve as an APRN preceptor or mentor. This includes participation in confidential peer health assistance programs. Physicians must verify their own license status before agreeing to serve in this role.
- Prescribing hours not accurately documented. The 750-hour mentorship must be documented. Both the physician and the APRN should maintain records of mentorship hours, prescribing decisions reviewed, and clinical guidance provided. Undocumented hours cannot be counted toward the 750-hour requirement.
- Articulated Plan not developed jointly. The Articulated Plan must be a jointly developed document that reflects how the APRN will maintain ongoing collaboration with physicians and other providers in their prescribing practice. A generic plan prepared by one party and signed by the other does not reflect the mutual development the framework requires.
- Three-year window not tracked. The APRN must complete the 750-hour mentorship within three years of receiving provisional prescriptive authority. Physicians in long-term mentorship relationships should know where the APRN stands relative to that window and plan accordingly.
- Population focus mismatch between preceptor and APRN. The mentorship must occur within the APRN’s role and population focus. A physician whose practice is entirely outside the APRN’s specialty may provide a less defensible mentorship experience if the Board reviews the arrangement.

Clinics Also Need to Understand Colorado Collaboration Requirements
While this guide primarily covers the physician’s role in Colorado’s APRN prescribing mentorship framework, these regulations directly affect clinics of all types operating in the state. APRN-operated clinics with fully authorized RXN practitioners need no physician collaboration. Clinics employing NPs who are still in the provisional prescriptive authority stage must ensure those NPs have a qualified preceptor in place so the 750-hour mentorship can be completed within the three-year window.
Need Help Finding a Colorado Collaborating Physician?
For clinics that employ NPs who hold provisional prescriptive authority, the next challenge is finding a qualified physician preceptor who has no current license restrictions, whose specialty is relevant to the APRN’s population focus, and who is prepared to engage genuinely in the 750-hour documented mentorship and the joint development of the Articulated Plan. Whether you are launching a new clinic with an NP in the provisional authority stage, managing multiple NPs at different stages of the mentorship pathway, or navigating the PA collaboration requirements that remain active regardless of APRN practice authority, having the right physician relationship in place matters.
If your clinic is actively looking for a Colorado collaborating physician, our team can match you with a qualified physician, often within 24 to 48 hours. We work with clinics across Colorado to simplify the physician matching process while supporting prescribing mentorship documentation, Articulated Plan development, and long-term collaboration needs.
Final Thoughts
Colorado collaborating physician requirements reflect a full-practice-authority state where physician involvement in APRN practice is defined, limited, and structured around a specific prescribing mentorship period rather than a career-long collaboration obligation. The 750-hour mentorship with its Articulated Plan requirement is the primary active context for physician involvement in Colorado NP prescribing, and it is a genuine clinical partnership, not a formality.
For physicians entering the Colorado mentorship market, the most important steps are confirming clean licensure status before serving as a preceptor, aligning with the APRN’s specialty and population focus, documenting mentorship hours and prescribing reviews consistently, and developing the Articulated Plan jointly with the APRN so it reflects a genuine commitment to safe prescribing practice.

Frequently Asked Questions
Does a Colorado NP with full prescriptive authority need a collaborating physician?
No. Colorado APRNs who hold full prescriptive authority (RXN designation on the Advanced Practice Registry) may prescribe independently without any physician collaboration agreement, protocol, or oversight. Colorado is a full-practice-authority state, and fully authorized APRNs are recognized as independent providers under state law.
What is the 750-hour prescribing mentorship in Colorado?
The 750-hour prescribing mentorship is a structured, documented period of supervised prescribing that Colorado APRNs must complete to advance from Provisional Prescriptive Authority (RXN-P) to Full Prescriptive Authority (RXN). The mentorship must be completed with an approved preceptor, who may be either a physician with an active Colorado license and no disciplinary restrictions, or an APRN who already holds full prescriptive authority in a comparable role and population focus.
Does the Colorado prescribing mentorship preceptor have to be a physician?
No. Under CRS § 12-255-112 and Colorado Board of Nursing Rules Chapter 15, the 750-hour prescribing mentorship may be completed under a physician or an APRN who holds full prescriptive authority in the same or comparable specialty and population focus. The physician is one of two qualifying preceptor types, not the exclusive option.
What is the Articulated Plan in Colorado?
The Articulated Plan is a written document developed jointly by the APRN and their preceptor as part of the prescribing mentorship. It must include a strategy for safe prescribing within the APRN’s role and population focus and outline how the APRN intends to maintain ongoing collaboration with physicians and other health care professionals in their prescribing practice.
How long does the Colorado prescribing mentorship have to be completed?
The 750-hour prescribing mentorship must be completed within three years of the APRN receiving provisional prescriptive authority. If the mentorship is not completed within the three-year window, the APRN cannot advance to full prescriptive authority without addressing the incomplete mentorship with the Colorado Board of Nursing.
Can a Colorado physician with a disciplinary restriction serve as an APRN preceptor?
No. A physician with any current restriction, limitation, or condition on their Colorado medical license cannot serve as an APRN preceptor or mentor. This includes confidential participation in a peer health assistance or alternative to discipline program. Physicians must hold a clean, unrestricted Colorado license to qualify as a preceptor for the 750-hour prescribing mentorship.
