Supervision Agreement for Certified Registered Nurse Anesthetists in Wisconsin
Yes, a written supervising-physician agreement is required. Wisconsin does not name a specific instrument.
Same APRN Modernization Act transition threshold applies to CRNAs as to NP/CNS — Wisconsin does not carve out a stricter framework for CRNAs the way some states (e.g. UT) do.
Independent practice requires: ≥3,840 hours of professional RN practice over ≥24 months; ≥3,840 hours of advanced practice in the CRNA's Recognized Role while working with a physician or dentist immediately available for consultation, over ≥24 months.
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
below the 3,840-hour/24-month transition threshold: Available remotely (no on-site requirement)
No geographic proximity requirement; collaborating physician/dentist must be immediately available in person or by telecommunication.

Chart review

Prescriptive authority
Covered by the practice agreement · controlled substances permitted
Schedule II-V with DEA registration, same as other Wisconsin APRN roles; scope is typically periprocedural/anesthesia-related in practice, though no statutory scope limit specific to that context was located.
Written agreement
Required
Practice ownership (corporate practice of medicine)
Licensee-only ownership required — Service Corporation under Wis. Stat. ch. 180, subch. XIX — CRNAs ('nurse anesthetist') are named alongside physicians as an exception to the mandatory-malpractice-insurance rule for shareholders practicing outside physician direction (§ 180.1911), suggesting the statute treats CRNA supervision status distinctly from other APRN roles for that narrow purpose.

About Wisconsin's rules
The APRN Modernization Act (2025 Act 17) took effect September 1, 2026 — days before this data's last-verified date — replacing permanent NP/CRNA/CNS collaborative arrangements with a 3,840-hour/24-month transition to independent practice; CNMs are auto-licensed with NO such threshold. Given how recent this is, verify current DSPS/Board of Nursing implementation guidance before relying on transition-period details below.
