WA HB2558

Narrows eligibility for mental health sentencing alternative to defendants with psychotic disorders (schizophrenia, schizoaffective disorder, bipolar disorder with psychotic features) rather than the broader category of "serious mental illness"

Adds domestic violence offenses against intimate partners as disqualifying crimes, unless both the victim and prosecuting attorney consent to the defendant's participation

Requires courts to find that the defendant's untreated psychotic disorder was a significant contributing factor in the offense and that the disorder can be appropriately managed with psychotropic medications

Mandates monthly progress hearings for the first six months and quarterly hearings thereafter, with courts required to increase hearing frequency if compliance concerns arise

Directs the Health Care Authority to contract with 1-4 providers specializing in psychiatric medicine to conduct mental health assessments and treatment plan development for participants
