PMHNP · Ohio
Supervision Agreement for Psychiatric Mental Health Nurse Practitioners in Ohio
Yes, a written supervising-physician agreement is required. Ohio does not name a specific instrument.
Same SCA framework as general `np` — PMHNP is a certification within the CNP role, not a separately codified category. OAC 4723-8-04 contemplates an ANCC/AANPCB-certified psychiatric-mental-health CNP entering the same standard-care-arrangement process as any other CNP, with no independent-practice carve-out found.
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` — no codified proximity/mileage standard.
Supervision ratio
Up to 5 at a time (combined across provider types)
Same shared cap as `np` (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` (OAC 4723-8-05) — no PMHNP-specific deviation found.
Prescriptive authority
Covered by the practice agreement · controlled substances permitted
Same Schedule II terminal-condition/72-hour/institutional-setting framework as `np` (§4723.481) — CONFIRMED no drug-class-based carve-out exists for psychiatric medications specifically (restrictions apply uniformly across Schedule II substances). The practical tension this could create for psychiatric prescribing (e.g. Schedule II stimulants) is meaningfully softened by the institutional-settings exemption, which includes community mental health providers and outpatient behavioral-health practices with employed-physician collaboration — settings much of PMHNP practice likely occurs from (see `np`'s restrictions for the full list).
Written agreement
Required
Same SCA requirement as `np`. Possible specialty-matching flexibility: a psychiatric-mental-health-certified provider may be allowed to collaborate with a physician in psychiatry, pediatrics, OR primary/family care rather than requiring an exact specialty match — directly confirmed for the parallel PMH-CNS role via the Ohio Board of Nursing's official guide, but not independently confirmed for PMHNP specifically; treated as likely-parallel.
Practice ownership (corporate practice of medicine)
Non-licensee ownership permitted — Same framework as `np` — no PMHNP-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.
