A Washington workers’ compensation claim starts with a Report of Accident filed with the Department of Labor and Industries, and you have one year from the date of a workplace injury (or two years from the date a doctor tells you in writing that you have a work-related occupational disease) to get it in. An approved claim pays the full cost of medical treatment, replaces 60 to 75 percent of your wages while you can’t work, and can provide a lump-sum award for permanent impairment or funding for retraining if you can’t return to your old job. The system is no-fault: you don’t have to prove your employer did anything wrong, and in exchange you generally can’t sue your employer over the injury.
The Deadlines That Matter First
Two clocks run from the moment you’re hurt, and missing either one can end your claim before it starts.
For a sudden workplace injury, you have one year from the date of injury to file. For an occupational disease that develops over time, you have two years from the date a doctor gives you written notice that your condition is work-related and that you may file a claim. Both deadlines come from RCW 51.28.050 and are enforced strictly.
Separately, report the accident to your employer as soon as it happens. Your employer is supposed to notify L&I once you’ve received medical treatment, missed work, been hospitalized, or died as a result. Don’t rely on that. File your own claim so the statutory window closes on your terms, not theirs.
How to File the Claim
The claim document is called the Report of Accident, or ROA. You fill out your part (name, Social Security number, date of birth, employer’s name and location, the date and time of the incident, what you were doing when it happened, and any witnesses), and a medical provider fills out the other part with a diagnosis, clinical findings, and a statement confirming the condition is work-related.
The fastest route is L&I’s FileFast online portal, which your treating provider can submit electronically. Electronic filing gets your claim into the system sooner and speeds up treatment authorization. Paper forms can be faxed or mailed instead, and you can pick them up at a doctor’s office, from your employer, or on the L&I website.
Once L&I has the ROA, your claim gets a unique claim number. That number tracks every piece of medical treatment, correspondence, and payment going forward, so keep it somewhere you can find it. L&I notifies your employer and gives them a chance to respond.
What Counts as a Covered Injury or Illness
Washington recognizes two categories of compensable conditions, and the category your situation falls into controls the proof you’ll need.
An industrial injury is a sudden, identifiable event with a prompt physical result. A fall from scaffolding, a burn from hot equipment, a hand caught in machinery. The statute calls for something “tangible” and “traumatic,” meaning one specific incident rather than a gradual breakdown.
An occupational disease develops over time from workplace exposure. Carpal tunnel from assembly-line work, hearing loss from prolonged noise, respiratory illness from chemical fumes. To qualify, the condition has to arise naturally from the job and be tied to conditions specific to that work, not an ordinary disease of life that the general public faces outside of work.
Mental Health Claims Are Narrow
Purely mental health claims are mostly excluded. Under RCW 51.08.142, stress-related mental conditions generally do not qualify as occupational diseases. The legislature carved out PTSD for firefighters, law enforcement officers, public safety dispatchers, and direct care registered nurses, and even for them, PTSD is not compensable if it stems from good-faith disciplinary action, job evaluations, transfers, demotions, or termination. If your mental health condition grew out of a physical workplace injury, it can still be covered as part of that injury claim no matter what job you hold.
Who Is Covered
Washington treats coverage as the default. The question isn’t whether you’re on a list of covered workers; it’s whether you fall into one of the specific exclusions. L&I decides independent contractor status by looking at whether the hiring entity controls how and when the work gets done, and contract language saying otherwise doesn’t settle it.
The exclusions under RCW 51.12.020 are narrower than most people expect:
- Domestic workers in a private home where the employer has fewer than two workers regularly working 40-plus hours per week.
- Casual laborers hired for work outside the employer’s regular trade or business.
- Sole proprietors and partners, who may voluntarily elect coverage but aren’t automatically included.
- Certain corporate officers and LLC members who are also directors and shareholders and who primarily manage rather than perform manual labor.
- Volunteers for religious or charitable organizations who serve only in exchange for aid or sustenance.
- Children under 18 employed by their parents in agricultural work on the family farm.
- Newspaper carriers and vendors acting as independent contractors.
Workers at self-insured employers get the same legal protections as workers covered through the State Fund. Only the funding source differs.
What an Approved Claim Pays
How much you receive depends on how badly you’re hurt and how long it keeps you off work.
Medical Treatment
L&I covers the full cost of medical treatment related to your workplace condition: doctor visits, surgery, prescriptions, physical therapy. No deductible, no copay. Treatment has to be authorized and provided by an L&I-approved provider, and your treating doctor becomes a central figure throughout the life of the claim.
Time-Loss Compensation
If your injury keeps you from working, time-loss compensation replaces part of your wages. The base rate is 60 percent of your gross monthly wages if you’re single with no dependents. Add 5 percent for a spouse or domestic partner, and 2 percent for each dependent child up to five children. A married worker with five or more children hits the 75 percent ceiling.
There’s a three-day waiting period before benefits begin. You won’t be paid for those three days unless you’re still unable to work on the seventh day after your injury, at which point the waiting period is paid retroactively. Time-loss is capped at a monthly maximum tied to the statewide average wage, which L&I updates annually.
Permanent Partial Disability Awards
When your condition stabilizes but leaves lasting impairment, you may receive a permanent partial disability (PPD) award. These are lump-sum payments calculated as a percentage of the total bodily impairment value, which for injuries occurring between July 2025 and June 2026 is $264,332.13. The percentage depends on which body part is affected and how severe the rating is. A Category 5 cervical spine impairment is rated at 35 percent, producing roughly $92,500. A Category 2 dorsolumbar impairment at 5 percent would yield about $13,200.
Vocational Retraining
If you can’t go back to your old job because of the injury, L&I may authorize vocational retraining. Two options exist, each with a maximum training budget of $20,914.12 (adjusted each July 1). Option 1 follows an L&I-approved plan built by a vocational rehabilitation counselor, with a two-year time limit. Option 2 lets you develop your own plan and pick your own L&I-approved program, with a five-year limit. Both cover tuition and training costs.
When the Claim Winds Down
At some point your treating doctor will decide that more treatment isn’t likely to significantly improve your condition. That point is called maximum medical improvement, or MMI. Reaching it doesn’t automatically cut off all medical care; you may still need ongoing treatment, medications, or therapy. But time-loss compensation typically ends, and L&I evaluates whether you qualify for a permanent disability rating. If you have lasting impairment, your PPD award is calculated now. If the injury leaves you permanently and totally unable to work, you may qualify for ongoing permanent total disability benefits instead.
If L&I Denies the Claim or You Disagree With a Decision
You have 60 calendar days from receiving an L&I decision to protest it or appeal. For decisions specifically about vocational benefits, the window shrinks to 15 days. Miss the deadline and the decision becomes final and binding.
A protest goes to your claim manager at L&I. Write a letter explaining why you disagree, put your claim number on every page, include the date and type of decision you’re challenging, and attach any supporting medical documentation. You can submit through L&I’s online Claim and Account Center or by mail.
You can also skip the protest and appeal straight to the Board of Industrial Insurance Appeals (BIIA). The board notifies L&I and gives the department a chance to reconsider. If L&I holds its position, the board schedules a hearing. BIIA proceedings are formal and resemble a court case, which is where legal representation starts to carry real weight.
When You Can Sue Someone Besides Your Employer
Workers’ compensation is your exclusive remedy against your employer. You can’t sue your employer in civil court for a workplace injury, even if the employer was clearly at fault. That trade-off is the whole deal: guaranteed benefits without proving fault, in exchange for giving up the right to sue.
A third party is different. If a subcontractor’s negligence, a defective product, or another driver’s recklessness caused your injury on the job, you can bring a personal injury suit against that third party and collect workers’ comp at the same time. RCW 51.24.060 sets out how any recovery gets divided: legal costs and attorney fees are shared proportionally, you receive 25 percent of the remaining balance, and L&I is reimbursed for benefits already paid. Anything left after that goes to you. L&I then pauses further benefit payments until the remaining balance (minus L&I’s share of costs) is exhausted, and benefits resume afterward as if the third-party recovery hadn’t happened.
These cases can substantially increase total compensation compared to workers’ comp alone, particularly when the injury involves serious permanent disability or significant lost future earnings.
What a Lawyer Can Charge
Washington caps attorney fees in workers’ compensation cases. For services before L&I, an attorney cannot charge more than 30 percent of the increase in benefits secured through their representation, and the fee has to be approved by L&I’s director. If your case goes to the BIIA on appeal and you win additional benefits, the board sets a reasonable fee subject to the same general limit. For claim resolution structured settlement agreements, the cap drops to 15 percent of the total paid to you after the agreement becomes final.
You don’t need an attorney to file a claim or to protest a decision. Representation matters more at the BIIA appeal stage and for complex issues like permanent total disability determinations or third-party suits.
