Ohio collaborating physician requirements apply to a large and active healthcare market with permanent physician oversight obligations for nurse practitioners. Ohio is a restricted-practice state for APRNs. The Standard Care Arrangement requirement does not expire after accumulating experience hours, and there is no pathway to independent APRN practice regardless of years in the field. Every certified nurse practitioner, certified nurse-midwife, and clinical nurse specialist in Ohio must maintain a written SCA with a collaborating physician for the full duration of their practice.
For physicians considering a collaboration role in Ohio, the compliance framework is specific and governed by Ohio Revised Code § 4723.431 and Ohio Administrative Code Chapter 4723-8. Understanding the specialty similarity requirement, the exclusionary formulary, the physician availability standard, and the termination obligations before entering any arrangement is essential. This guide covers every requirement a physician needs to understand in 2026.
Ohio Collaborating Physician Overview: Where Ohio Stands
Ohio classifies APRNs in the restricted-practice category with no independence pathway. The SCA requirement applies to certified nurse practitioners (CNPs), certified nurse-midwives (CNMs), and clinical nurse specialists (CNSs). All three must practice only in accordance with a Standard Care Arrangement entered into with each physician or podiatrist with whom the nurse collaborates.
Governing Body
The Ohio Board of Nursing governs APRN licensure, SCA requirements, and board notification obligations under ORC § 4723.431 and OAC Chapter 4723-8. The State Medical Board of Ohio governs physician licensure and retains independent disciplinary authority over physicians participating in SCAs. The APRN’s prescriptive authority may not exceed that of the collaborating physician, meaning restrictions on the physician’s license directly limit the APRN’s prescribing scope.
The Legislative Landscape
House Bill 508, introduced in 2025, would remove the SCA requirement entirely and allow Ohio APRNs to practice independently. As of the publication of this guide, HB 508 has not been enacted. The SCA requirement remains in force, and physicians entering Ohio collaboration arrangements should monitor the status of this legislation, as its passage would materially change the demand for physician collaboration in this state.
The Standard Care Arrangement: Ohio’s Core Compliance Document
Under ORC § 4723.431(A)(1), a CNP, CNM, or CNS may practice only in accordance with a Standard Care Arrangement entered into with each physician or podiatrist with whom the nurse collaborates. A copy of the SCA must be retained on file by the nurse’s employer.
The SCA is defined under ORC § 4723.01(N) as a written, formal guide for planning and evaluating a patient’s health care that is developed by one or more collaborating physicians or podiatrists and a CNS, CNM, or CNP and meets the requirements of ORC § 4723.431.
Filing and Retention
The SCA does not need to be filed with the Ohio Board of Nursing before practice begins. The OBON may request to review the SCA at any time. The agreement must be retained on file by the employer and be available for inspection. Under Ohio law, the SCA must be retained for a minimum of three years.
The SCA must be reviewed and re-approved at least annually. Each annual review must be documented as part of the agreement.
What Must Be in an Ohio SCA
Ohio Administrative Code Rule 4723-8-04 and ORC § 4723.431 specify the required content of a valid Standard Care Arrangement. The agreement must address all of the following:
1. Scope of Practice and Authorized Actions
The SCA may specify actions the APRN is authorized to take or is prohibited from taking as part of the nurse’s practice in collaboration with the physician. The SCA shall not authorize any action that is otherwise prohibited by the Revised Code or board rules.
2. Criteria for Referral and Consultation
The agreement must include criteria for when the CNP, CNS, or CNM must refer a patient to the collaborating physician or podiatrist, or to other physicians, specialists, or health care facilities. It must also include a procedure for regular review of those referrals.
3. Process for Obtaining Consultation
The SCA must describe a process for the APRN to obtain consultation with the collaborating physician when clinical situations require it.
4. Chart Review Process
The SCA must establish a process for chart review in accordance with OAC §§ 4723-8-04 and 4723-8-05. The frequency and method of review are determined by the parties and documented in the agreement.
5. Infant and Pediatric Care Statement
The SCA must include a statement regarding the health care of infants up to the age of one and recommendations for provider visits through three years of age.
6. Emergency and Absence Coverage Plan
The agreement must include a plan for coverage of patients in instances of emergencies or planned absences of either the APRN or the collaborating physician.
7. Dispute Resolution Process
The SCA must describe a process for resolution of disputes regarding patient care or management between the APRN and the collaborating physician.
8. Annual Review Requirement
The SCA must include quality assurance measures, including periodic review and re-approval of the arrangement on at least an annual basis.
9. Death Certificate Obligation
Under ORC § 4723.431(A)(5), the SCA must include an agreement that the collaborating physician will complete and sign the medical certificate of death for the APRN’s patients when required under ORC § 3705.16.
Board Notification Requirements
Ohio requires the APRN to notify the Ohio Board of Nursing of the collaborating physician’s identity at two points under OAC Rule 4723-8-04(H) and ORC § 4723.431:
- Within 30 days of first engaging in practice as a CNP, CNS, or CNM, the nurse must submit to the Board the name and business address of each collaborating physician or podiatrist.
- Within 30 days of any change in the collaborating physician’s name or business address, the nurse must notify the Board.
The physician does not file the SCA with any board. The notification obligation belongs to the APRN. However, physicians entering Ohio collaboration arrangements should confirm that the APRN has submitted the required board notification and maintain their own record of the arrangement start date.
At license renewal, the APRN uploads a document with the collaborating physician’s information through the Ohio eLicensing system. If a change occurs between renewals, the APRN submits updated information through the same portal.
Physician Eligibility and the Specialty Similarity Standard
A Ohio collaborating physician must hold a current, active license to practice medicine or osteopathic medicine in Ohio under ORC § 4723.431(A)(2). The physician must be authorized to practice in Ohio and must be practicing in a specialty that is the same as or similar to the APRN’s nursing specialty. The physician’s practice must be at least similar. An identical specialty match is not required, but meaningful overlap must exist.
The Psychiatric-Mental Health Exception
Under ORC § 4723.431(A)(2)(c) and OAC Rule 4723-8-04(C), a CNS certified as a psychiatric-mental health CNS or a CNP certified as a psychiatric-mental health NP may enter into an SCA with a physician practicing in any of the following specialties:
- Psychiatry
- Pediatrics
- Primary care
- Family practice
This expanded list reflects the real-world clinical context for psychiatric APRNs and avoids unnecessarily restricting collaboration to psychiatrists only.
Prescriptive Authority Cannot Exceed the Physician’s
One critical practical point: under ORC § 4723.481(B), an APRN’s prescriptive authority cannot exceed that of the collaborating physician. If the collaborating physician is restricted from prescribing controlled substances by the State Medical Board or the DEA, that restriction flows directly to the APRN. Physicians should disclose any prescribing restrictions to the APRN before the SCA is signed.
Physician Availability: What Collaboration Means in Ohio
Under ORC § 4723.01(L), collaboration means that one or more physicians with whom the APRN has entered into an SCA are continuously available to communicate with the CNP or CNS either in person or by radio, telephone, or other form of telecommunication.
Continuous availability does not mean constant physical presence. Ohio does not impose a geographic proximity requirement on collaborating physicians. A physician in Columbus can serve as a collaborating physician for a CNP practice in Cleveland. Remote collaboration is fully permitted.
What it does mean is that the physician must be reachable at all times when the APRN is practicing under the arrangement. A collaborating physician who is regularly unreachable during the APRN’s practice hours is not meeting the statutory definition of collaboration.
Prescriptive Authority and the Exclusionary Formulary
Ohio uses an exclusionary formulary approach for APRN prescribing under OAC Rule 4723-9-10. An APRN may prescribe any drug or device that is not expressly excluded by the exclusionary formulary, so long as the prescription is also consistent with the terms of the SCA and does not exceed the collaborating physician’s own prescriptive authority.
Conditions for Valid APRN Prescriptions in Ohio
Under OAC Rule 4723-9-10, for an APRN’s prescription to be valid, all of the following must apply:
- The APRN holds a current, valid license and certificate to prescribe
- The prescription is consistent with the terms of the SCA
- The prescription does not exceed the prescriptive authority of the collaborating physician
- The drug or device is not excluded by the exclusionary formulary
- The prescription meets all state and federal law requirements
- A valid prescriber-patient relationship exists
What the Exclusionary Formulary Means in Practice
The exclusionary formulary lists specific drugs, drug subtypes, or therapeutic devices that APRNs may not prescribe or furnish. Physicians and APRNs should review the current formulary together when drafting the SCA to ensure the authorized drug categories are accurate. The Ohio Board of Nursing publishes the current exclusionary formulary at nursing.ohio.gov.
Controlled Substance Prescribing in Ohio
APRNs in Ohio may prescribe controlled substances within the terms of the SCA and consistent with the exclusionary formulary. Ohio does not impose a blanket prohibition on Schedule II prescribing for APRNs practicing under an SCA.
OARRS Requirement
Under OAC Rule 4723-9-12, APRNs prescribing controlled substances must check the Ohio Automated Rx Reporting System (OARRS) under certain mandatory circumstances. The SCA must describe the APRN’s process for OARRS compliance and documentation of findings.
DEA Registration
APRNs prescribing controlled substances must hold a current DEA registration. Prescriptive authority for controlled substances is subject to the same ceiling as the collaborating physician’s authority. If the physician lacks DEA registration or has a restricted DEA registration, the APRN’s controlled substance prescribing is limited accordingly.
The Physician-to-APRN Ratio in Ohio
Under ORC § 4723.431, if a collaborating physician enters into SCAs with more than five nurses, the physician shall not collaborate at the same time with more than five nurses in the prescribing component of their practice.
What This Means
A physician can have SCAs with more than five APRNs but cannot simultaneously supervise more than five APRNs in the prescribing component of practice at any one time. The practical effect for most outpatient collaboration arrangements is a cap of five concurrent prescribing APRNs per physician.
Hospital Exemption
This limitation does not apply to collaborative arrangements of hospital employees providing inpatient care services. The ratio applies to outpatient, clinic-based, and independent practice settings.
Termination Obligations and the 120-Day Grace Period
Ohio provides a structured termination process that includes a meaningful protection for APRNs when collaboration ends unexpectedly.
Physician’s Termination Obligations
Under ORC § 4723.431(D)(1), if the physician terminates the collaboration before the SCA expires:
- The physician must give the APRN written or electronic notice of the termination
- The APRN must notify the Ohio Board of Nursing of the termination as soon as practicable by submitting a copy of the physician’s termination notice
The 120-Day Grace Period
After submitting the termination notice to the Board, the APRN may continue to practice under the existing SCA without a collaborating physician for up to 120 days. This grace period gives the APRN time to find a replacement collaborating physician without an immediate gap in practice. The 120-day window is not automatic and requires timely board notification.
If the collaboration terminates because of the physician’s death, the APRN must notify the Board as soon as practicable.
Common Compliance Mistakes Ohio Collaborating Physicians Make
Most Ohio SCA compliance problems come from documentation gaps, specialty mismatches, and failure to understand the prescriptive authority ceiling.
- Specialty mismatch between physician and APRN. The physician’s specialty must be the same as or similar to the APRN’s nursing specialty. A physician whose practice has no meaningful overlap with the APRN’s clinical area does not satisfy the similarity standard and creates compliance exposure for both parties.
- Prescriptive authority restrictions not disclosed. The APRN’s prescriptive authority cannot exceed the physician’s. A physician with DEA restrictions or State Medical Board prescribing limitations must disclose those restrictions to the APRN before signing the SCA. Failure to do so results in the APRN unknowingly operating beyond their legal prescribing scope.
- Annual review not documented. The SCA must be reviewed and re-approved at least annually. Documentation of the review must be maintained as part of the arrangement. Undocumented annual reviews leave the agreement without a current compliance record.
- Board notification not filed within 30 days. The APRN must notify the Ohio Board of Nursing of the collaborating physician’s identity within 30 days of engaging in practice, and within 30 days of any change. Physicians should confirm this notification has been filed and maintain their own record.
- Ratio exceeded. A physician may not collaborate with more than five APRNs in the prescribing component of practice simultaneously. Physicians with multiple clinic arrangements need to track their active prescribing APRN count across all arrangements.
- Physician unreachable during APRN’s practice hours. Continuous availability is a statutory element of collaboration in Ohio. A physician who is consistently unreachable when the APRN is seeing patients is not meeting the legal definition of collaboration regardless of what the SCA states.

Clinics Also Need to Understand Ohio Collaboration Requirements
While this guide primarily covers the responsibilities and compliance requirements placed on collaborating physicians in Ohio, these regulations directly affect CNP-owned clinics, medspas, and healthcare practices that depend on physician collaboration to operate. In many cases, clinic owners researching Ohio collaboration rules are also trying to understand how to find a qualified physician relationship that satisfies the specialty similarity standard and the continuous availability requirement.
Need Help Finding an Ohio Collaborating Physician?
For clinics, understanding the legal requirements is only one part of the process. The next challenge is finding a qualified physician whose specialty is the same as or similar to the APRN’s nursing specialty, who is available for continuous telecommunication during practice hours, and who understands Ohio’s exclusionary formulary and prescriptive authority ceiling rules. Whether you are launching a new clinic, replacing a physician whose SCA has been terminated, or navigating the 120-day grace period and need a new collaborating physician quickly, having the right physician relationship in place is essential.
If your clinic is actively looking for an Ohio collaborating physician, our team can match you with a qualified physician, often within 24 to 48 hours. We work with clinics across Ohio to simplify the physician matching process while supporting onboarding, SCA documentation, board notification filings, and long-term collaboration needs.
Final Thoughts
Ohio collaborating physician requirements are built around a permanent, structured oversight framework that applies for the full duration of an APRN’s career. The Standard Care Arrangement is not a background document. It is the legal instrument governing every prescription the APRN writes and every clinical act performed under the physician’s collaboration. The specialty similarity standard, the prescriptive authority ceiling, and the continuous availability obligation are all active compliance requirements from the day the SCA is signed.
For physicians entering the Ohio market, the compliance framework is workable when the SCA is drafted specifically, the specialty match is genuine, and the annual review is consistently documented. An arrangement built on those foundations holds up under scrutiny from either the Ohio Board of Nursing or the State Medical Board of Ohio.

Frequently Asked Questions
Does an Ohio collaborating physician need to be physically present at the APRN’s clinic?
No. Ohio does not impose a geographic proximity requirement on collaborating physicians. Remote collaboration is fully permitted. However, collaboration under ORC § 4723.01(L) requires the physician to be continuously available to communicate with the APRN either in person or by phone or other telecommunications. The physician must be reachable at all times when the APRN is practicing under the arrangement.
How often does an Ohio SCA need to be reviewed?
The Standard Care Arrangement must be reviewed and re-approved at least annually. Documentation of each annual review must be maintained as part of the agreement. The agreement itself must be retained for a minimum of three years.
Does the SCA need to be filed with the Ohio Board of Nursing?
No. The SCA does not need to be filed with the OBON before practice begins. The agreement must be retained on file by the APRN’s employer and made available to the Board upon request. The APRN must notify the Board of the collaborating physician’s name and business address within 30 days of starting practice, and within 30 days of any change.
How many APRNs can one Ohio physician collaborate with?
A physician may not collaborate with more than five APRNs in the prescribing component of practice simultaneously. A physician can have SCAs with more than five nurses, but may not supervise more than five in the prescribing component at any one time. Hospital inpatient collaborative arrangements are exempt from this limit.
What happens when an Ohio physician terminates a Standard Care Arrangement?
The physician must provide written or electronic notice of the termination to the APRN. The APRN must notify the Ohio Board of Nursing as soon as practicable by submitting a copy of the termination notice. After submitting that notice, the APRN may continue to practice under the existing SCA without a collaborating physician for up to 120 days, giving time to secure a replacement.
Does the APRN’s prescriptive authority in Ohio depend on the physician’s license status?
Yes. Under ORC § 4723.481(B), an APRN’s prescriptive authority cannot exceed that of the collaborating physician. If the physician has restrictions on their prescribing authority, those restrictions flow directly to the APRN’s practice under the SCA. Physicians must disclose any such restrictions before the SCA is signed.
