Medical malpractice claims in Washington are governed by a special statute of limitations under RCW 4.16.350. The rules are more complex than the standard three-year injury deadline, and missing them can end a valid claim.
The Core Timing Rules
Under RCW 4.16.350, a medical malpractice claim must generally be filed within three years of the negligent act or omission, OR within one year of the date the patient discovered (or reasonably should have discovered) the injury — whichever is later.
There is also an outer limit, or statute of repose: in most cases, no claim may be brought more than eight years after the act, regardless of when the injury was discovered.
Why Discovery Matters in Medical Cases
Medical injuries are often hidden. A surgical error, a misread scan, or a delayed diagnosis may not cause obvious harm for months or years. The discovery rule exists because it would be unfair to start the clock before the patient could reasonably know they were harmed.
Insurers and hospital defense teams frequently dispute when a patient 'should have known,' making early legal review important.
Other Requirements
Washington previously required a mandatory pre-suit notice and certificate of merit, though some of these provisions have been limited by court decisions. The procedural landscape is complex and evolving.
