How to report a workplace injury, file a workers' compensation claim, and meet deadlines in Washington.

Filing a workers' compensation claim in Washington involves specific steps and deadlines that must be followed carefully §51.04.010.

Step 1: Report the Injury

You must report your workplace injury to your employer within Worker must report the accident to the employer forthwith; employer must report qualifying injuries to L&I at once (immediately) §51.28.010; §51.28.025. Written notice is always recommended even if verbal notice is given.

⚠Failure to give timely notice can be used by the employer or insurer as grounds to deny your claim.

Step 2: Get Medical Treatment

1
Tell the doctor your injury is work-related
2
Follow the treatment plan completely

Keep copies of all medical records and bills
4
Report any work restrictions to your employer

Step 3: File the Formal Claim

Claims managed by L&I; protests and appeals heard by the Board of Industrial Insurance Appeals (BIIA) §51.52.050.

Step 4: Investigation and Response
