Medical Malpractice Laws in Washington.
Washington has no caps on medical malpractice damages — a 1986 cap was struck down as unconstitutional. The statute of limitations is 3 years from the act or 1 year from discovery, whichever is later. The 8-year statute of repose was ruled unconstitutional in 2023 (Bennett v. United States). Mandatory mediation is required before trial, and the pre-suit mediation request tolls the SOL for 1 year. The certificate of merit requirement was also struck down as unconstitutional.
