Signed into law · Washington Senate · Co-sponsor
Making improvements to transparency and accountability in the prior authorization determination process.

Maddy summarySB 5395 requires health insurance carriers in Washington to improve transparency in prior authorization decisions for medical treatments and prescriptions. It sets strict time limits: carriers must decide on electronic standard requests within 3 days and expedited requests within 1 day, with clear communication if more information is needed. The bill mandates that denials include the credentials of the reviewing provider and requires carriers to use evidence-based clinical criteria that are updated annually and accessible in plain language. These rules directly affect insurance companies, doctors, and patients by making coverage decisions faster and more transparent.

Concerning the use of face coverings by law enforcement officers.

Maddy summaryThis bill requires Washington law enforcement officers to wear visible identification (like a clearly displayed name) and not cover their faces during routine public interactions. It defines "facial covering" to exclude medical masks, helmets for bicycle safety, and clear face shields, but prohibits items like balaclavas or tactical masks. Exceptions allow face coverings during active undercover operations or when tactical teams use protective gear for safety. Officers who violate this during detentions could face civil lawsuits seeking damages or court-ordered remedies. The law applies to all police officers during public duties, not just emergency situations.

Concerning the creation of building codes for kit homes.

Maddy summarySB 5552 aims to create a new category of building codes specifically for "kit homes" to increase affordable housing options. The bill defines kit homes as residential structures 800 square feet or smaller, built from prefabricated walls, floors, and roofs assembled on-site. It directs the State Building Code Council to establish these specific building codes for kit homes by December 31, 2025. This initiative is intended to provide more affordable small homes for homebuyers of modest means.

Passed · Washington Senate · Co-sponsor
Providing tax relief to Washington residents impacted by the atmospheric river and winter weather event.

Maddy summarySB 6343 provides property tax relief to Washington homeowners whose property was damaged or destroyed by the atmospheric river and winter weather events. It allows for reduced property valuations and tax refunds if the property lost over 20% value in a declared disaster area, with refunds calculated based on days remaining in the tax year after the damage. The bill also creates a three-year tax exemption for physical improvements to single-family homes rebuilt after qualifying disasters, limited to the value reduction amount. This relief applies to properties in areas declared disaster zones by the governor or county authority, with applications due by October 1, 2026, for recent weather events.

Addressing artificial intelligence, student discipline, and surveillance in public schools.

Maddy summarySB 5956 prohibits Washington public schools from using artificial intelligence (AI) or surveillance technologies to make or solely determine student discipline decisions, such as suspensions or expulsions. It bans "risk scores" predicting student misconduct, biometric tracking for emotional/mental health analysis, and automated watchlists, requiring human review for any discipline action involving AI or surveillance data. The law directly affects all K-12 public school districts, charter schools, and tribal education programs in Washington, mandating updates to policies to prevent discriminatory impacts on students of color, students with disabilities, and LGBTQ students. It also restricts sharing student data with law enforcement except in emergencies involving imminent serious physical harm.

Prohibiting interest charges for new and unpaid medical debt.

Maddy summarySB 5993 caps interest charges on new and unpaid medical debt at 1% per year, directly affecting patients with outstanding medical bills. The bill amends Washington law to prohibit interest above this rate, including for debt accrued before or after a court judgment. It excludes from the cap certain medical debt that is invalid, waived under state law, or unenforceable. This policy change reduces financial burdens for individuals struggling with medical debt while maintaining existing legal enforcement mechanisms for valid claims.

Recognizing Diwali and Bandi Chhor Divas.

Maddy summaryThis bill adds Diwali and Bandi Chhor Divas to Washington State's list of officially recognized days under RCW 1.16.050, specifically in section (7)(w). It does not create a paid holiday or alter employee leave policies; these days are recognized for ceremonial purposes only, similar to other designated observances like Eid al-Fitr. The recognition applies to state government practices but does not grant employees additional paid time off or change existing holiday entitlements. This change aligns with Washington's existing framework for acknowledging cultural and religious observances without legal holiday status.

Supporting the recovery of missing persons.

Maddy summaryWashington State's SB 6070 requires law enforcement to obtain a court order before using certain surveillance tools - including pen registers, trap and trace devices, and cell site simulators (devices that mimic cell towers) - to locate missing endangered persons. The bill amends existing laws to specify that these tools may only be deployed when investigating a missing person who qualifies as "endangered" under state law. Courts must approve such orders based on probable cause that the tools will help locate the missing person or gather evidence related to their disappearance. This law directly affects law enforcement agencies conducting missing persons investigations and ensures judicial oversight for these intrusive surveillance methods.

Concerning endometriosis.

Maddy summarySB 5985 requires the University of Washington (with Washington State University and stakeholders) to create an online resource center by July 1, 2028, providing evidence-based materials on endometriosis diagnosis, care, and communication tools for healthcare providers. It also mandates that Washington’s Office of Public Instruction update school health education standards to include menstrual health awareness, helping students recognize symptoms that may indicate endometriosis. The online resource center must be updated every three years and expire December 31, 2031, while the school curriculum changes expire June 30, 2029. This bill directly affects residents with endometriosis, healthcare systems, and public school students across Washington state.
