Collaborative Drug Therapy Management for Nurse Practitioners in Wisconsin
Yes, a written agreement with a physician is required before you prescribe and adjust drug therapy. Wisconsin calls it a Collaborative Arrangement.
New as of the APRN Modernization Act (2025 Act 17), eff. Sept. 1, 2026 — replaces Wisconsin's prior permanent collaborative-arrangement model. Employers, medical staff bylaws, credentialing standards, and payors may still require a collaborative agreement even after Board authorization to practice independently — this is a licensure floor, not a ceiling on private contracts.
Independent practice requires: ≥3,840 hours of professional RN practice over ≥24 months (shortfall against 24 months, if any, is added to the APRN-role requirement below); ≥3,840 hours of advanced practice in the NP's Recognized Role while working with a physician or dentist immediately available for consultation, over ≥24 months.
What the physician relationship 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)
Under both the prior (Wis. Stat. § 441.16, WAC ch. N 8) and current frameworks, Wisconsin imposes no geographic proximity requirement — the collaborating physician/dentist need only be 'immediately available for consultation and referral,' in person or by telecommunication.
Supervision ratio
Not codified — no cap on file
Chart review
Not codified — left to the agreement
Meeting cadence
Not codified — left to the agreement
Prescriptive authority
Covered by the practice agreement · controlled substances permitted
Pain-management NPs using invasive techniques must continue collaborating with a pain-medicine physician even after reaching independent-practice status (secondary-sourced characterization of Act 17 — verify against final DSPS rule text).
Written agreement
Required
Practice ownership (corporate practice of medicine)
Licensee-only ownership required — Service Corporation under Wis. Stat. ch. 180, subch. XIX — NPs, as health care professionals, may co-own a multi-discipline service corporation alongside physicians or other licensees; non-licensees may not hold equity.
An NP shareholder practicing independently (not under physician direction, post-transition) must independently carry malpractice coverage meeting § 655.23(4) minimums (§ 180.1911).

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.
