Concerning evidence of medical, hospital, or similar expenses occasioned by an injury.

HB 2571 changes how medical expense evidence is used in lawsuits against local governments in Washington State. It prohibits using billed medical, hospital, or similar expense amounts to prove damages in civil cases or related arbitration/mediation for personal injuries. Instead, plaintiffs must show only the actual amount they paid for these expenses. This applies to all local governments, including cities, counties, school districts, hospital districts, and other special districts defined in the bill. The law directly affects injury victims suing local entities over medical costs.
