Connecticut collaborating physician requirements apply to a transitional-practice state with a defined and time-limited collaboration period for all newly licensed APRNs. Connecticut General Statutes § 20-87a requires that every APRN practice in collaboration with a Connecticut-licensed physician for the first three years after initial Connecticut licensure and for a minimum of 2,000 hours. Once both the time and hours thresholds are met and the APRN provides written notice to the Department of Public Health, full independent practice authority is granted.
For physicians entering collaboration roles in Connecticut, the compliance framework centers on the three-year collaborative period, the written agreement required specifically for prescriptive authority, the controlled substance authorization structure that applies during collaboration, and the documentation obligations that allow the APRN to eventually transition to independent practice. This guide covers every requirement a physician needs to understand in 2026, sourced directly from CGS § 20-87a and Connecticut DPH guidance.
Connecticut Collaborating Physician Overview: Where Connecticut Stands
Connecticut is classified as a transitional-practice state. The collaboration requirement applies specifically to newly licensed APRNs for their first three years of Connecticut practice. It is not a career-long obligation. After meeting both thresholds, time and hours, an APRN becomes a fully independent practitioner.
Governing Body
The Connecticut Department of Public Health (DPH), through its Board of Examiners for Nursing, governs APRN licensure, collaborative practice requirements, prescriptive authority, and disciplinary matters under CGS § 20-87a and related statutes.
The Collaboration Requirement Applies to All APRN Categories
The three-year collaboration requirement applies to all Connecticut-licensed APRN categories, including certified nurse practitioners, certified nurse midwives, clinical nurse specialists, and certified registered nurse anesthetists, with specific additional rules for CRNAs prescribing during surgery. This guide primarily addresses the NP and CNM context most relevant to the physician collaboration market.
The Three-Year Collaborative Practice Requirement: What It Covers
Under CGS § 20-87a, for the first three years after obtaining a Connecticut APRN license, every APRN must practice in collaboration with a physician licensed in Connecticut. Collaboration is defined in the statute as a mutually agreed upon relationship between the APRN and a physician whose education, training, or experience is related to the work of the APRN.
What Collaboration Encompasses
Under CGS § 20-87a(b), the collaboration must address all of the following:
- A reasonable and appropriate level of consultation and referral between the APRN and the physician
- Coverage for the patient in the absence of the APRN
- A method to review patient outcomes
- A method of disclosure of the relationship to the patient
These four elements define the minimum scope of every Connecticut collaboration arrangement during the three-year period. A relationship that does not address all four is not compliant with the statutory definition of collaboration.
What Collaboration Does Not Require
Connecticut collaboration during the three-year period does not require:
- A specific ratio of charts reviewed or a numerical review frequency beyond the agreement’s patient outcome review method
- Physical presence of the physician at the APRN’s practice location
- Prior approval or filing of the agreement with the DPH
- The physician to be the APRN’s employer or to hold any authority over the APRN’s clinical decisions
The Written Agreement Is Required Only for Prescriptive Practice
Under CGS § 20-87a(b), written documentation of the collaboration is specifically required for the APRN to exercise prescriptive authority. For clinical practice, including diagnosing and treating patients, the statute does not require the collaboration to be in writing. For prescribing, including controlled substances, the collaboration must be documented in a written agreement. In practice, because most Connecticut APRN clinics involve prescribing, the written agreement is the operational standard for almost all collaboration arrangements.
The Written Collaborative Agreement: When It Is Required
The written collaborative agreement is required when the APRN will exercise prescriptive authority during the three-year collaborative period. The DPH confirms that it will not collect copies of collaborative practice agreements on a routine basis. The written agreement is maintained by both the APRN and the physician and must be available when requested.
No Board Pre-Approval Required
Connecticut does not require the collaborative agreement to be submitted to the DPH before the APRN begins prescribing. The agreement must exist, be in writing, address the required elements, and be available when the DPH requests it. The absence of a pre-approval requirement does not reduce the importance of having a complete, signed, and current agreement in place.
DPH Public Profiling Requirement
Under CGS § 20-13j, the DPH must collect information to create individual public profiles for health care providers including APRNs. Each APRN’s public profile must indicate whether the APRN is practicing independently or in collaboration with a physician under a collaborative agreement. This distinction appears in the APRN’s public DPH record and is visible to patients and payers.
What the Connecticut Collaborative Agreement Must Address
For prescriptive practice, the written collaborative agreement under CGS § 20-87a(b) must address all of the following:
1. The Level of Schedule II and III Controlled Substances
The agreement must specify which Schedule II and Schedule III controlled substances the APRN is authorized to prescribe. This is not a general authorization. The specific substances or categories authorized must be named in the agreement. An agreement that authorizes general prescribing without specifically addressing Schedule II and III controlled substance levels does not satisfy this requirement.
2. A Method to Review Patient Outcomes
The agreement must include a method to review patient outcomes, including the review of medical therapeutics, corrective measures, laboratory tests, and other diagnostic procedures that the APRN may prescribe, dispense, and administer. The method must be described in the agreement. The frequency and scope of that review are determined by the parties, but the mechanism must be documented.
3. Consultation and Referral Level
The agreement must address a reasonable and appropriate level of consultation and referral between the APRN and the physician. This describes how the APRN will access the physician for clinical questions and how patients with complex needs will be referred.
4. Patient Coverage During APRN Absence
The agreement must address how patient care will be covered when the APRN is absent. The coverage plan must reflect a genuine continuity-of-care structure for the APRN’s patient population.
5. Patient Disclosure Method
The agreement must include a method by which the collaborative relationship will be disclosed to patients. Patients must know that the APRN is practicing in collaboration with a physician during the three-year period.
Physician Eligibility: The Related Experience Standard
A Connecticut collaborating physician must hold a current, active Connecticut medical license. The physician must be educated, trained, or have relevant experience related to the work of the APRN.
The Related Experience Standard
Connecticut does not use a strict specialty match requirement. The statute requires that the physician’s education, training, or experience is related to the APRN’s work. This is a functional standard that asks whether the physician can meaningfully contribute to the consultation, referral, and patient outcome review obligations the collaboration creates. A family medicine physician collaborating with a family NP satisfies this standard clearly. A physician whose entire clinical background has no connection to the APRN’s patient population will find it difficult to argue their experience is related to the APRN’s work.
Physician Must Be Connecticut-Licensed
The collaborating physician must be licensed in Connecticut. An out-of-state physician, even one licensed in a neighboring state, does not satisfy the Connecticut physician requirement for the statutory collaboration.
No Geographic Proximity Requirement
Connecticut does not impose a geographic proximity requirement on collaborating physicians. The physician does not need to practice near the APRN’s clinic location. Remote collaboration provided by phone or electronic communication satisfies the availability standard.
No Ratio Limit
Connecticut does not impose a statutory cap on the number of APRNs a physician may collaborate with simultaneously.
Schedule II and III Controlled Substance Authorization
The controlled substance prescribing framework during the Connecticut collaboration period distinguishes this state from both full-practice-authority states and permanently restricted-practice states.
During the Three-Year Collaborative Period
An APRN in the collaborative period may prescribe Schedule II, III, IV, and V controlled substances. However, the written collaborative agreement must specifically address the level of Schedule II and Schedule III controlled substances the APRN may prescribe. Schedule IV and V controlled substances may be prescribed under the agreement without the same specificity requirement.
This means the agreement must name the Schedule II and III substances or categories the APRN is authorized to prescribe. A physician who is uncomfortable delegating Schedule II authority must explicitly exclude those substances from the agreement. Silence on Schedule II authorization does not constitute blanket exclusion.
After the Three-Year Period
Once the APRN completes the three-year/2,000-hour requirement and notifies DPH of independent practice, the controlled substance authorization structure changes. An APRN practicing independently may prescribe Schedule II through V controlled substances without the need for agreement-specified authorization levels. The physician collaboration structure for prescribing ends entirely.
The DPH Notification and Documentation Requirements
The Written Notification Before Practicing Independently
Before an APRN who has met the three-year and 2,000-hour requirements begins practicing without a collaborative agreement, the APRN must submit written notice to the DPH of their intention to do so. This notification must be submitted prior to practicing without collaboration.
Documentation Retention Requirements
Under CGS § 20-87a(b), an APRN who elects to practice independently must maintain documentation of completion of the three-year/2,000-hour collaborative requirement for not less than three years after completing the requirement. The APRN must submit that documentation to the DPH within 45 days of the DPH’s request.
What Documentation Must Show
The documentation must demonstrate:
- That the APRN has held a Connecticut APRN license for a period of not less than three years
- That the APRN has engaged in the performance of advanced practice level nursing activities in collaboration with a Connecticut-licensed physician for not less than three years and not less than 2,000 hours
The physician’s role in this documentation process is practical, not procedural. The APRN bears the responsibility for maintaining the records, but the records must accurately reflect the collaboration. A physician who collaborates with an APRN but maintains no records of the hours or nature of the collaboration may be asked to attest to information they cannot document.
After Three Years and 2,000 Hours: Independent Practice
Once an APRN has met both the time and hours thresholds and filed the written notice with the DPH, the APRN may practice either alone or in collaboration with a physician or another health care provider licensed to practice in Connecticut. The physician collaboration requirement ends.
What This Transition Means for Physicians
When an APRN completes the three-year/2,000-hour requirement and provides DPH notice, the physician’s collaboration role ends. The physician is not required to take any action to enable the transition. The collaborative agreement becomes unnecessary for the APRN’s practice authority. Some APRNs choose to maintain voluntary physician relationships after independence for clinical, institutional, or professional reasons, but those are elective arrangements rather than statutory requirements.
What Independent APRNs May Do That Collaborating APRNs Cannot
Connecticut law draws a distinction between APRNs in the collaborative period and those who have achieved independent status in at least one context.
Under CGS § 21a-70f, starting in 2015, manufacturers of covered drugs, devices, biologicals, and medical supplies must annually report information on payments or other transfers of value made to APRNs who are not practicing in collaboration with a physician. This reporting requirement applies specifically to independent APRNs and reflects their elevated profile as independent prescribers.
Additionally, Connecticut’s medical marijuana program recognizes APRNs as providers who may recommend medical marijuana to qualifying patients. CRNAs prescribing and administering medical therapeutics during surgery must do so under specific conditions that differ from standard APRN prescriptive practice.
The Out-of-State Practitioner Rule
One of the most important and sometimes overlooked aspects of Connecticut’s framework is that the three-year/2,000-hour requirement applies to the first three years after Connecticut licensure, regardless of prior APRN practice experience in other states.
What This Means
An APRN who has practiced for ten years in a full-practice-authority state such as Oregon or Colorado must still complete a full three-year/2,000-hour collaborative practice period when they first obtain a Connecticut APRN license. Prior APRN practice in another jurisdiction, even a full-practice-authority jurisdiction, does not satisfy or waive the Connecticut requirement.
This rule distinguishes Connecticut from Massachusetts, which counts prior APRN practice in non-supervised states as equivalent to supervised practice years. Connecticut draws no such equivalency. Every newly Connecticut-licensed APRN enters the three-year collaborative period from the beginning.
Prescriptive Authority During and After Collaboration
During the Collaborative Period
APRNs in the three-year collaborative period may prescribe Schedule II through V controlled substances within the specific authorization levels described in the written collaborative agreement. DEA registration is required. The agreement must name the authorized Schedule II and III substances.
Prescription forms used by Connecticut APRNs must include the APRN’s name, address, and telephone number. The form may also include the collaborating physician’s name if appropriate under the circumstances.
After the Collaborative Period
Independent APRNs may prescribe any medication within their scope, including Schedule II through V controlled substances, without the need for a written agreement specifying controlled substance levels. DEA registration remains required.
Common Compliance Mistakes Connecticut Collaborating Physicians Make
Most Connecticut collaborative agreement compliance problems involve inadequate written agreement content, documentation gaps, and failure to understand the controlled substance specification requirement.
- Written agreement does not specify Schedule II and III controlled substances. The agreement must name the level of Schedule II and III controlled substances the APRN may prescribe. A general authorization for controlled substance prescribing without specifying these schedules does not satisfy CGS § 20-87a(b). The physician must either authorize specific Schedule II and III substances or explicitly exclude them.
- No method to review patient outcomes described. The agreement must include a method for reviewing patient outcomes, including medical therapeutics and diagnostic procedures. An agreement that mentions collaboration generally without specifying the review mechanism does not satisfy the statutory requirement.
- Physician is not Connecticut-licensed. The collaborating physician must hold a current Connecticut medical license. An out-of-state physician does not satisfy the CGS § 20-87a requirement for the three-year collaborative period regardless of their qualifications.
- No patient disclosure method in the agreement. The agreement must include a method of disclosure of the collaboration relationship to the patient. Agreements that address clinical processes but omit patient disclosure do not satisfy the statutory requirements.
- Not maintaining records that could support the APRN’s independence documentation. When the APRN applies for independent practice, they need to demonstrate the 3-year/2,000-hour collaborative period was completed. A physician who maintains no records of the collaboration hours or activities cannot support that documentation accurately.
- Treating all controlled substances the same. During the collaboration period, Schedule II and III require specific authorization in the agreement. Schedule IV and V do not require the same specificity. Applying one approach to all schedules creates either over-restriction or under-authorization.

Clinics Also Need to Understand Connecticut Collaboration Requirements
While this guide primarily covers the physician collaboration requirements in Connecticut, these regulations directly affect NP-operated clinics, medspas, and healthcare practices that depend on physician collaboration for their newly licensed APRNs. In many cases, clinic owners researching Connecticut collaboration rules are also trying to understand how to find a Connecticut-licensed physician whose experience is related to the APRN’s clinical area, who understands the Schedule II and III controlled substance specification requirement, and who can support the APRN’s documentation of collaborative hours toward eventual independence.
Need Help Finding a Connecticut Collaborating Physician?
For clinics, understanding the legal requirements is only one part of the process. The next challenge is finding a qualified Connecticut-licensed physician who understands the three-year transitional structure, is prepared to draft a written agreement that correctly specifies Schedule II and III controlled substance authorization levels, and can support the APRN’s documentation of the 2,000-hour requirement for eventual DPH notification of independent practice. Whether you are launching a new Connecticut clinic with a newly licensed APRN, replacing a physician mid-way through the three-year period, or approaching the independence threshold and needing to ensure documentation is complete, having the right physician in place matters.
If your clinic is actively looking for a Connecticut collaborating physician, our team can match you with a qualified physician, often within 24 to 48 hours. We work with clinics across Connecticut to simplify the physician matching process while supporting collaborative agreement drafting, Schedule II and III authorization documentation, and long-term collaboration needs.
Final Thoughts
Connecticut collaborating physician requirements reflect a state that has resolved the permanent-versus-independent collaboration debate by creating a defined, time-limited transition period for all newly licensed APRNs. The three-year/2,000-hour requirement is precise, applies regardless of prior out-of-state experience, and carries specific documentation obligations that ultimately support the APRN’s transition to full independence. The written agreement requirement is specifically triggered by prescriptive authority and must address controlled substance authorization at a level of specificity Connecticut does not leave to interpretation.
For physicians entering the Connecticut market, the most important steps are ensuring the written agreement specifically names the authorized Schedule II and III controlled substances, includes all five required elements, and is maintained in a way that supports the APRN’s eventual independence documentation.

Frequently Asked Questions
How long does a Connecticut APRN need to collaborate with a physician?
Under CGS § 20-87a, every APRN must collaborate with a Connecticut-licensed physician for the first three years after obtaining a Connecticut APRN license and for a minimum of 2,000 hours. Both the time and hours thresholds must be met. After completing both requirements and filing written notice with the DPH, the APRN may practice independently.
Does a Connecticut APRN who practiced in another state still need to complete the three-year collaborative period?
Yes. Connecticut’s three-year collaborative practice requirement applies from the date of initial Connecticut APRN licensure, regardless of how many years the APRN practiced in any other state. There is no equivalency provision for out-of-state experience. Every newly Connecticut-licensed APRN starts the three-year period from scratch.
Does the collaborative agreement need to be filed with the Connecticut DPH?
No. The Connecticut DPH states that it will not collect copies of collaborative practice agreements on a routine basis. The agreement must be maintained by both the APRN and the physician and submitted to the DPH within 45 days of a DPH request. The APRN is also required to maintain documentation of the 2,000-hour collaborative period for at least three years after completing the requirement.
What controlled substances can a Connecticut APRN prescribe during the three-year collaborative period?
An APRN in the collaborative period may prescribe Schedule II through V controlled substances. However, the written collaborative agreement must specifically address the level of Schedule II and III controlled substances the APRN is authorized to prescribe. Schedule IV and V controlled substances may be prescribed without the same specificity requirement.
Does the collaborating physician need to be physically present at the APRN’s clinic?
No. Connecticut does not impose a geographic proximity requirement on collaborating physicians. The physician does not need to be located near the APRN’s practice location. The collaboration must address a reasonable level of consultation and referral, patient coverage, and outcome review, but those obligations may be fulfilled remotely.
How many APRNs can one Connecticut physician collaborate with?
Connecticut does not impose a statutory cap on the number of APRNs a physician may collaborate with simultaneously. The physician must be able to genuinely fulfill the consultation, outcome review, and coverage obligations of each active collaboration arrangement.
