Supervision Agreement for Clinical Nurse Specialists in Ohio
Yes, a written supervising-physician agreement is required. Ohio does not name a specific instrument.
No independence pathway exists regardless of tenure. Unlike some other states' CNS role, Ohio's CNS has the SAME full prescriptive-authority grant as CNM/NP — confirmed directly ('A CNS in collaboration with one or more physicians may prescribe drugs and therapeutic devices'), no narrower carve-out found.
Independent practice requires: Same SCA framework as `np`/`cnm` (Ohio Rev. Code §4723.431/§4723.43(D)) — no hours- or experience-based exit exists; unlike `cnm`, the CNS's collaborator may be a physician OR a podiatrist.
What the supervision must look like
The rules the physician relationship has to follow. Each fact comes from the statute or board rule listed under sources.
Proximity
No proximity requirement
Same as `np`/`cnm` — no codified proximity/mileage standard.
Supervision ratio
Up to 5 at a time (combined across provider types)
Same shared cap as `np`/`cnm` (Ohio Rev. Code §4723.431).
Chart review
Not codified — left to the agreement
Meeting cadence
Annually, in person or via telehealth
Same annual/semiannual chart-review-plus-conference cycle as `np`/`cnm` (OAC 4723-8-05).
Prescriptive authority
Covered by the practice agreement · controlled substances permitted
Same Schedule II/exclusionary-formulary/OARRS/abortion-drug-prohibition framework as `np`/`cnm` (§4723.481, §4723.151(C)) — full prescriptive authority, no CNS-specific narrowing found. Nationally-recognized CNS certifications in Ohio include Adult-Gerontology, Pediatrics, Neonatal, and Psychiatric-Mental Health (PMHCNS).
Written agreement
Required
Unconditional — written SCA required with a collaborating physician OR podiatrist (if podiatrist-collaborating, scope limited to procedures the podiatrist is authorized to perform, Ohio Rev. Code §4731.51). Generally requires specialty-matching between the CNS and collaborator, EXCEPT Psychiatric-Mental-Health-certified CNSs, who may collaborate with a physician in psychiatry, pediatrics, or primary/family care instead.
Practice ownership (corporate practice of medicine)
Non-licensee ownership permitted — Same framework as `np`/`cnm` — no CNS-specific ownership rule found.

About Ohio's rules
Ohio recently relaxed CRNA supervision from 'immediate presence' to facility-wide 'collaboration' (H.B. 52, eff. 6/8/2026, now current law), and will loosen RN laser-delegation rules similarly (H.B. 377, eff. 8/25/2026 — NOT yet law as of this file's date). No independent-practice pathway exists for NP/PMHNP/PA despite active pending reform bills (a 2,000-hour NP threshold, PA proximity removal) — none enacted. Ohio has no corporate-practice-of-medicine doctrine (State Medical Board, 2012). Non-nurse midwifery has no current licensure pathway.
