Ohio: Ownership and Oversight
Moderate CPOM; SCA model with a 5-APRN prescribing cap. Ohio permits flexible business structures but runs tight, well-defined oversight: every APRN needs a standard care arrangement with a same-specialty Ohio physician, and the prescribing side carries a hard five-nurse cap.
Who the statute actually covers
- "Standard care arrangement" (SCA) (ORC § 4723.431): the written agreement between a CNP, CNM, or CNS and each collaborating physician or podiatrist; no Board pre-approval, retained by the employer, subject to Board review. The collaborating physician must be Ohio-authorized, actively engaged in direct clinical practice, and practicing in the same or a similar specialty; on-site presence is not required but a back-up plan is.
- The 5-nurse prescribing cap (§ 4723.431(A)(1)): a physician or podiatrist with SCAs covering more than five nurses may not collaborate at the same time with more than five nurses in the prescribing component of their practices. Outside prescribing, no numeric cap.
- "Supervision agreement" (ORC § 4730.19): the PA-side written agreement with a supervising physician describing delegated services, prescriptive delegation, and review mechanics; State Medical Board jurisdiction.
- Entity posture: Ohio permits physicians to provide services through authorized entities and permits non-physician ownership and management of business operations; risk arises when lay actors control diagnosis, treatment, prescribing, supervision, or medical records. Professional associations under ORC Ch. 1785 are available but not the only lane.
1. Who can own what
| Entity / Path | Who may own | Key limits |
|---|---|---|
| Physician practice entities | Professional associations (ORC Ch. 1785, licensee-owned) or other authorized structures; lay business ownership tolerated where clinical control stays with licensees. | State Medical Board polices lay interference, delegation, and fee-splitting. |
| APRN-owned practice | Viable; the APRN entity operates under the owner's SCA with a qualifying collaborating physician. | The 5-prescriber cap makes collaborating-physician capacity a real constraint; specialty match mandatory. |
| PA path | No distinct ownership lane; PAs practice under supervision agreements. | |
| Lay / MSO | Workable with clean clinical/business separation; injectables and device-based aesthetics are medical acts requiring physician oversight (§ 4731.22; OAC 4731-18). | Ohio medspa enforcement runs through the delegation rules. |
2. Collaborative and supervisory oversight
| Role | Agreement required | Oversight mechanics | Path to independence |
|---|---|---|---|
| PA | Written supervision agreement with a supervising physician (ORC § 4730.19) covering delegated services, prescriptive delegation (Board-issued prescriber number required), and review mechanics. | No statutory chart-review percentage; mechanics agreement-defined. Verify current State Medical Board rules on concurrent-supervision limits. | None. Ohio PAs have no independence pathway. |
| NP / APRN | Written SCA with each collaborating physician or podiatrist (§ 4723.431); employer retains it; collaborating physician names filed with the Board of Nursing within 30 days. | Same/similar specialty required; physician continuously available but not on-site; back-up plan required. Max 5 nurses per physician in prescribing at any one time. Prescriptive authority may not exceed the collaborating physician's own; exclusionary formulary governs; Schedule II carries setting-based restrictions. If physician terminates, APRN may continue under existing SCA for up to 120 days. | None. Ohio is a permanent-collaboration state for CNPs, CNMs, CNSs; CRNAs practice under supervision with immediate-presence requirements. |

Practical read: Ohio's five-prescriber cap is the binding constraint nobody models: a multi-site APRN group needs collaborating-physician capacity planned like any other scarce resource, specialty-matched and Ohio-active. And the 120-day continuation rule is genuinely useful in transitions — almost no other state gives an APRN four months of runway after losing a collaborator.
