Relating to: reports on the competency of involuntarily committed individuals to refuse medication or treatment based upon an examination by an advanced practice registered nurse.

SB 646 amends Wisconsin statute 51.61(1)(g)3 to allow reports assessing whether involuntarily committed individuals can refuse mental health treatment to be based on examinations by advanced practice registered nurses (APRNs) with psychiatric expertise, not just physicians. This directly affects individuals in involuntary mental health commitments and expands the healthcare professionals authorized to certify treatment necessity and competency to refuse care. The bill requires such reports to include a signed statement from the APRN or physician confirming the individual needs treatment and lacks competence to refuse it. The change takes effect September 1, 2026, after a transitional period allowing either physicians or qualified APRNs to issue these reports until that date. The law maintains existing court hearing requirements for treatment decisions but broadens who can provide the foundational medical assessment.
