Medical malpractice in Washington
No enforceable damages cap
Washington medical malpractice claims generally have no enforceable statutory ceiling on economic or noneconomic damages. Timing is usually the later of three years from the care at issue or one year from discovery that the care caused the injury.

Damage caps
There is currently no enforceable statutory noneconomic damages cap for ordinary medical malpractice after Sofie and the later repeal of the old formula statute. Do not rely on any printed age-based formula as current law.
Not capped
Economic damages
Economic damages in an ordinary medical malpractice claim are limited by proof. Washington does not set a general statutory ceiling on those losses.
No cap
Noneconomic damages
There is currently no enforceable statutory noneconomic damages cap for ordinary medical malpractice. The 1986 formula in former RCW 4.56.250 was held unconstitutional under the jury-trial guarantee in the Washington Constitution, article I, section 21. The section was later repealed.
Do not rely on any printed age-based formula as current law. A secondary source that still quotes the repealed formula is stale.
Sofie v. Fibreboard Corp.. In 1989, the Washington Supreme Court held the noneconomic damages formula unconstitutional. Former RCW 4.56.250 was later repealed. This page does not show that formula as a current cap.
Punitive damages
Washington does not generally award punitive damages in ordinary personal-injury negligence. Confirm any statutory exception on the facts of the case.
Filing deadlines
File within three years of the act or omission, or within one year of discovery that the injury was caused by that care, whichever ends later. The eight-year outer limit still printed in the statute is not treated as enforceable after Washington Supreme Court rulings. A good-faith mediation request can toll the clock for one year. Mediation is generally required before trial.
- General rule
Commence the action within three years of the act or omission alleged to have caused the injury, or within one year from when the patient or representative discovered or reasonably should have discovered that the injury was caused by that act or omission, whichever period expires later.
- Printed repose
The statute still contains language that says the claim is barred in no event after eight years. That repose was held unconstitutional in DeYoung (1998), reenacted with legislative findings in 2006, and again held unconstitutional in Bennett v. United States (2023). Do not treat the eight-year bar as enforceable.
- Tolling
Fraud, intentional concealment, or a foreign body not intended for a therapeutic or diagnostic purpose can toll the period until actual knowledge. The claimant then has one year to sue.
- Mediation tolling
A written good-faith mediation request before filing tolls RCW 4.16.350 for one year.
- Mediation before trial
Health care damage actions are generally subject to mandatory mediation before a superior court trial. That requirement is not a pre-suit notice barrier. A former certificate-of-merit statute was held unconstitutional and later repealed. Do not treat a certificate of merit as a current filing requirement. Standard of care and causation still generally require qualified expert evidence at trial.
What cases often look like
These notes describe public legal patterns. They are not case counts, win rates, or rankings.
The noneconomic cap is not enforceable
Sofie struck the 1986 noneconomic formula, and the legislature later repealed that section. Landing copy should say there is no enforceable statutory noneconomic cap.
The printed eight-year repose is not enforced
RCW 4.16.350 still prints an eight-year outer limit. Washington Supreme Court rulings, including Bennett v. United States, do not treat that repose as enforceable.
Mediation is the remaining process gate
Mandatory mediation before trial is the main remaining statutory process gate. It is not a certificate-of-merit wall. Pure comparative fault can reduce recovery based on the plaintiff's share of fault. It does not bar recovery only because the plaintiff was partly at fault.
Payout context
Payment amounts vary by year, injury, and setting. This page does not state an average payout, a median, or a case count. To predict the payout for a Washington case, use MedMalPredict AI - Medical Malpractice Outcome Prediction.

Sources
Official statute and agency pages checked September 22, 2026. First research pass on September 22, 2026. This summary still needs legal review before it is treated as legal advice. There is no enforceable noneconomic or total medical malpractice damages cap after Sofie, and former RCW 4.56.250 was later repealed. Eight-year repose language is still printed in RCW 4.16.350, but it was held unconstitutional as reenacted in Bennett v. United States (2023), after an earlier invalidation in DeYoung (1998). The certificate-of-merit statute was struck and later repealed. Mandatory mediation before trial remains.
