A collaborative practice agreement (CPA) is a written agreement between a nurse practitioner and a supervising or collaborating physician that defines the scope of the NP's clinical practice. In most states with Reduced or Restricted Practice authority, an NP cannot legally see patients, prescribe, or order diagnostics without one. Getting the CPA right is therefore not a paperwork formality — it is the legal foundation of the NP's ability to practice.
This 2026 guide walks through where CPAs are required, what they typically must contain, how they must be filed, and the mistakes that most often trigger Board of Nursing investigations or delayed APRN license issuance.
Which States Require a CPA
The NCSBN classifies state APRN practice authority into three tiers:
- Full Practice (FPA): No CPA required. NPs evaluate, diagnose, prescribe, and manage treatment independently under the exclusive licensure authority of the Board of Nursing.
- Reduced Practice: A CPA or other collaborative relationship is required for at least one element of practice (commonly prescribing).
- Restricted Practice: Career-long supervision, delegation, or team management by a physician is required for the NP to provide patient care.
States such as Texas, Florida, North Carolina, South Carolina, and Georgia maintain some of the more prescriptive CPA frameworks, with detailed rules on chart review, prescribing parameters, and physician availability. Meanwhile, several states have moved away from CPAs entirely — California's AB890 created a pathway to drop the standardized procedure requirement after a transition-to-practice period, and other states have converted to FPA in recent legislative cycles. Always verify the current status with the state Board of Nursing before relying on any tier classification.
Elements Commonly Required in a CPA
While every state writes its own rules, most CPAs must address a similar core set of clinical and administrative elements:
- Scope of practice: The patient populations, conditions, and procedures the NP is authorized to manage.
- Prescriptive authority parameters: Drug categories, formulary limits, and any exclusions on Schedule II–V controlled substances.
- Consultation and referral protocols: When the NP must consult the collaborating physician, when patients must be referred out, and how consults are documented.
- Quality assurance plan: How clinical performance is monitored, including peer review and outcome tracking.
- Chart review frequency: Many states require the collaborating physician to review a specified percentage of charts (often a quarterly sample) and to sign off in writing.
- Controlled substance prescribing rules: Whether the NP may prescribe controlled substances at all, additional registrations required, and any quantity or refill limits.
- Physician availability: How the collaborating physician is reachable (in-person, by phone, by telehealth) and within what timeframe.
- Practice site information: Locations covered by the agreement; some states require a separate filing for each site.
Some states publish a mandatory CPA template or required-elements checklist; others leave the structure to the parties and only require that certain topics be addressed. Using a generic out-of-state template is one of the fastest ways to have a CPA rejected by the Board of Nursing.
Filing With the Board of Nursing
A common and costly misconception is that the CPA only needs to be kept on file in the practice. In many Reduced and Restricted states, the CPA — or a formal notice of collaboration — must be filed with the Board of Nursing (and sometimes the Board of Medicine) before the NP can legally bill or prescribe. Filing requirements may include:
- Submission within a defined number of days of execution.
- Re-filing whenever the collaborating physician, practice site, or scope changes.
- Annual or biennial attestation that the agreement remains in force.
- Notarization or physician license verification.
Failure to file is treated by some Boards as practicing without authorization, regardless of whether the underlying clinical work was within scope.
Quality Assurance and Chart Review
Quality assurance language is where states diverge most. Some require the collaborating physician to review a defined percentage of the NP's charts each quarter and to document the review in a log. Others require periodic in-person meetings, joint case conferences, or peer review committee participation. A few states tie chart review frequency to the NP's years of independent experience — with reduced oversight after a transition-to-practice period. Confirm the exact cadence with the state Board of Nursing rather than relying on prior employer templates.
What Happens When the Collaborating Physician Leaves
If the supervising or collaborating physician retires, dies, switches employers, or terminates the agreement, the NP's authority to practice typically ends immediately. This is one of the largest continuity-of-care risks in Restricted Practice states. Best practice is to:
- Identify a backup collaborating physician in advance and have a draft agreement ready.
- Track the physician's licensure status and DEA expiration alongside the NP's own.
- Notify the Board promptly — many states give only days, not weeks, to file a replacement agreement.
Specialty Considerations: CRNAs and CNMs
CRNAs generally do not operate under generic NP collaborative agreements. Anesthesia services are governed by separate supervision rules — often requiring an anesthesiologist, operating surgeon, or other qualified physician to supervise — and the federal CMS opt-out status of the state also affects what is required for facility billing. CNMs typically maintain their own collaborative agreements with an OB/GYN that address obstetric scope, hospital privileges, and emergency transfer protocols. Applying a generic NP CPA to a CRNA or CNM is a frequent and serious compliance error.
Common Pitfalls
- Generic templates: Downloading a CPA from a national association site that omits state-specific required elements.
- Keeping it in a drawer: Drafting and signing the CPA but never filing it with the Board.
- Failing to update: Not amending and re-filing when the physician, site, or scope changes.
- Confusing employment with collaboration: Assuming a W-2 relationship satisfies the CPA requirement — it does not.
- Ignoring controlled substance restrictions: Prescribing Schedule II medications under a CPA that excludes them.
- Stale quality assurance logs: Skipping the required chart-review percentage during busy periods.
