Collaborative Practice Agreements: A Complete Guide for NPs and PAs

Collaborative practice agreements (CPAs) are foundational documents in healthcare that define the working relationship between nurse practitioners or physician assistants and their collaborating physicians. In states that require physician oversight, these agreements are not just paperwork. They are the legal authority that allows NPs and PAs to diagnose, treat, and prescribe. Getting them right is essential for both clinical operations and regulatory compliance.

Whether you are a telehealth startup building a clinician network or an NP launching an independent practice, this guide covers everything you need to know about collaborative practice agreements.

What Is a Collaborative Practice Agreement?

A collaborative practice agreement is a formal, written document that outlines the scope, terms, and protocols of the professional relationship between an advanced practice provider (NP or PA) and a supervising or collaborating physician. Depending on the state, these agreements may also be called supervisory agreements, practice agreements, or delegation agreements.

The core purpose of a CPA is to establish:

• The scope of practice for the NP or PA, including what conditions they can treat and what procedures they can perform
• The prescriptive authority granted, including whether controlled substances are included
• The physician's oversight responsibilities, including chart review frequency and availability for consultation
• Communication protocols between the collaborating physician and the NP or PA
• Terms for renewal, amendment, and termination of the agreement

What Should a CPA Include?

While requirements vary by state, a comprehensive collaborative practice agreement typically contains the following elements:

Identification of Parties

Full legal names, license numbers, and credentials of both the collaborating physician and the NP or PA. The agreement should specify the physician's specialty and confirm it aligns with the NP's or PA's practice area.

Scope of Practice

A detailed description of the clinical services the NP or PA is authorized to provide. This may reference specific conditions, patient populations, or clinical settings. Some states require this section to reference state-specific formularies or clinical guidelines.

Prescriptive Authority

Specific provisions addressing what the NP or PA can prescribe, including whether controlled substances (Schedules II-V) are included. Many states require separate DEA registration and may impose additional limitations on controlled substance prescribing even under a CPA.

Chart Review Protocols

The agreement should specify how often the collaborating physician reviews patient charts. Common requirements include:

• Percentage of charts to be reviewed (often 10-20% of patient encounters)
• Timeframe for chart review completion (typically within 30 days)
• Documentation requirements for the review itself
• How findings and feedback are communicated to the NP or PA

Chart review is not a formality. State medical boards audit these records, and finding that a collaborating physician has never actually reviewed charts is one of the most common compliance failures we see in practice.

Consultation and Referral Procedures

Protocols for when and how the NP or PA should consult with the collaborating physician, including availability requirements. Most agreements specify that the physician must be available by phone or secure messaging during the NP's or PA's practice hours, even if they are not physically present.

State Requirements: A Patchwork Landscape

The requirements for collaborative practice agreements vary enormously by state. Understanding where your state falls on the spectrum is critical:

• Full practice authority states (approximately 27 states as of 2025) allow NPs to practice independently without a CPA after meeting certain experience requirements
• Reduced practice states require a CPA but may have less stringent oversight requirements
• Restricted practice states require CPAs with specific, detailed supervision protocols including in-person physician involvement

For PAs, the landscape is shifting. Many states have moved or are moving toward a model called "optimal team practice" that replaces traditional supervision requirements with a more collaborative framework. However, most states still require some form of physician-PA agreement.

Key State-Specific Variations

• Physician-to-NP/PA ratios: Some states limit how many NPs or PAs a single physician can collaborate with, ranging from 3 to 7 depending on the state
• Geographic proximity: Certain states require the collaborating physician to practice within a specified distance of the NP or PA
• On-site requirements: A few states mandate periodic in-person physician visits to the NP's or PA's practice location
• Filing requirements: Some states require CPAs to be filed with the state medical board, nursing board, or both

Physician Compensation for Collaboration

Compensating a collaborating physician requires careful attention to both fair market value and anti-kickback statute considerations. The compensation must reflect the actual time and expertise the physician provides and cannot be tied to the volume or value of referrals.

Common compensation structures include:

• Flat monthly retainer: A fixed fee for availability, chart review, and consultation, typically ranging from $1,500 to $5,000 per month depending on volume and specialty
• Per-chart-review fee: Payment based on the number of charts actually reviewed, often $15-50 per chart
• Hourly rate: Compensation for time spent on consultation, chart review, and meetings, typically at fair market rates for the physician's specialty

Never structure collaborating physician compensation as a percentage of revenue generated by the NP or PA. This creates fee-splitting concerns and potential anti-kickback violations that can jeopardize both the physician's license and your business.

Renewal and Termination

Every CPA should include clear provisions for both renewal and termination:

• Term length: Most CPAs are set for one to two-year terms with automatic renewal provisions
• Notice requirements: Typically 30-90 days written notice for termination by either party
• Transition planning: Procedures for transitioning patients and responsibilities when a CPA ends
• Wind-down obligations: The collaborating physician's responsibilities during the transition period, including continued chart review and consultation availability

For telehealth companies, having a backup collaborating physician plan is essential. If your sole collaborating physician terminates their agreement, your NPs and PAs may be unable to legally practice until a replacement is in place. Building redundancy into your physician network prevents this operational risk.

Common Compliance Pitfalls

Having worked with hundreds of healthcare companies on their collaborative practice arrangements, we see certain mistakes repeatedly:

1. Using a template CPA across all states without customizing for state-specific requirements
2. Failing to actually perform chart reviews at the frequency specified in the agreement
3. Not updating the CPA when scope of practice changes or new services are added
4. Allowing the CPA to lapse without renewal, leaving NPs and PAs practicing without proper authorization
5. Selecting a collaborating physician whose specialty does not align with the NP's or PA's practice area

A well-drafted collaborative practice agreement, properly executed and consistently followed, protects everyone involved: the NP or PA, the collaborating physician, the patients, and the business. Treat it as a living document that requires regular attention, not a form to file and forget.
