What Is the Average Settlement for Traumatic Brain Injury from WA L&I

A traumatic brain injury (TBI) can change everything from how you think and communicate to whether you can keep your job. Even if you look fine, memory loss, confusion, fatigue, or emotional changes can make it impossible to work. Washington State law allows compensation for job-related brain injuries, but the Department of Labor and Industries (L&I) doesn’t pay for pain. It pays for permanent disability. 

If your symptoms aren’t documented or rated correctly, your traumatic brain injury claim will be undervalued. Most insurance companies know this and try to get you to settle early. If your injury changed how you live or work, your claim has value, but you’ll need to fight to get it.

What Brain Injuries Qualify for Workers’ Compensation?

A mild traumatic brain injury (TBI) happens when a blow, jolt, or other force disrupts the brain’s normal function. Even a mild concussion can result in lasting symptoms such as memory loss, difficulty concentrating, headaches, mood swings, or speech problems. Washington law allows you to file a workers’ comp claim if your brain injury happened at work, or if work made a prior condition worse. These injuries aren’t always obvious, and they don’t always show up on an MRI. But they’re real, and compensable when properly documented.

Here are the most common traumatic brain injury cases we see in workers’ compensation claims:

Injury or Condition	How It Happens or Presents
Concussion	Sudden impact or whiplash causes short-term or lasting dysfunction, often without loss of consciousness.
Post-concussion syndrome	Lingering symptoms after a mild TBI: headaches, brain fog, light sensitivity, mood swings, fatigue.
Cerebral contusion	Brain bruising from direct impact; often includes confusion, dizziness, or behavior changes.
Traumatic axonal injury (TAI)	Shearing of brain tissue from high-speed or violent motion (e.g., falls, vehicle crashes). Often results in severe injuries.
Skull fracture with brain trauma	A bone fracture plus underlying brain injury can cause swelling, bleeding, or permanent damage.
Brain hemorrhage (subdural or epidural)	Internal bleeding after trauma can cause seizures, memory loss, and long-term deficits.
Seizure disorder (post-traumatic epilepsy)	Onset of seizures after brain injury may develop days, weeks, or months after impact.
Cognitive impairment without visible trauma	Problems with memory, focus, decision-making, or speech, even when scans are clear.
Work-aggravated pre-existing TBI	A prior brain injury worsens due to a fall, head bump, or repeated strain at work.
Chronic traumatic encephalopathy (CTE)	Long-term degeneration from repeated blows, common in high-risk fields like construction or law enforcement.
Anosmia / Ageusia (loss of smell or taste)	Often caused by damage to the olfactory nerve or brain structures near the nose or frontal lobe.

Any of these may qualify if there’s a medical link to your job. You don’t need to lose consciousness or show bleeding on a scan. What matters is the long-term impact and how it limits your ability to work or function.

What Is the Average Workers’ Comp Settlement for TBI?

According to NCCI data, active workers’ comp TBI claims between 2013 and 2018 averaged about $136,000 in total incurred costs, more than double the average for all lost-time claims, and around 2.5% of these claims exceeded one million dollars.

The NSC also reports that head and central nervous system injuries had the highest average lost-time claim cost compared to other injuries, about $91,844 per claim in 2021 and 2022. These figures reflect national workers’ comp costs, not Washington payouts. Still, they underscore a truth: brain injuries cost more, and the more serious the injury, the deeper their financial and life impact.

In Washington, mild brain injuries may qualify for low-end mental impairment ratings (e.g., Category 2 at about $25,700), while a more severe traumatic brain injury, involving seizures, speech issues, or major cognitive loss, may push a properly rated claim into the six-figure range. Combined ratings, when mental, convulsive (seizures), speech, and sensory loss are each documented and accepted, can significantly increase the final settlement amount.

How Brain Injuries Are Rated in Washington’s Partial Permanent Disability System

For traumatic brain injuries, the maximum award for total permanent disability under the mental health schedule is $185,032.50, according to the 2025 permanent partial disability (PPD) award schedule. 

Most workers receive a percentage of that amount, depending on the severity of their symptoms and the number of impairment categories that apply. Unlike a broken bone, a TBI might qualify for multiple ratings, including mental, seizure-related, speech-related, and sensory loss, each of which can be awarded separately and combined to increase your total settlement. Below are the four categories that most often apply to TBI victims in Washington.

Mental Health Impairments

Most TBI-related settlements start here. Washington classifies cognitive, emotional, and behavioral symptoms as “mental” impairments, including things like memory loss, poor concentration, confusion, irritability, anxiety, and post-traumatic stress disorder. These symptoms may not show up on a scan, but they can permanently affect your ability to work, focus, and interact with others.

L&I assigns a category rating from 2 to 5 based on a psychologist’s or psychiatrist’s evaluation. Each category corresponds to a percentage of total body impairment and a dollar value based on the most recent PPD schedule:

Category	% Impairment	Award
2	10%	$26,433.21
3	25%	$66,083.04
4	45%	$118,949.46
5	70%	$185,032.50

Example: A construction worker with a Category 4 rating for cognitive fog, emotional dysregulation, and short-term memory loss might receive $118,949.46, with additional awards possible if medical experts confirm that other categories apply.

Convulsive Disorder (Seizures)

Some traumatic brain injuries result in post-traumatic epilepsy or seizure disorders. These are classified separately under Washington’s PPD schedule and can significantly increase your overall TBI settlement if present. Labor and Industries considers the frequency and severity of seizures when assigning a rating, regardless of whether the seizures are fully controlled with medical treatment.

Category	% Impairment	Award
2	10%	$26,433.21
3	55%	$92,516.25
4	69%	$158,599.29

Example: A factory worker who experiences monthly tonic-clonic seizures post-TBI might be rated at Category 3, entitling them to around $92,516.25, depending on the impact on daily functioning and whether future medical care is required.

Speech Impairments

Brain injuries that affect the parts of the brain responsible for language, articulation, or verbal expression may qualify under the speech impairment schedule. These can include slurred speech, stuttering, difficulty finding words, or the complete loss of the ability to speak. Ratings reflect the severity and permanence of the impairment, as well as whether medical care is ongoing.

Category	% Impairment	Award
2	5%	$13,216.62
3	10%	$26,433.21
4	20%	$52,866.42
5	30%	$79,299.63
6	35%	$92,516.25

Example: A delivery driver who experiences chronic aphasia (difficulty forming or understanding words) after a car crash might receive a Category 5 rating, leading to an award of around $79,299.63, especially if the condition limits his ability to work with customers, coworkers, or even family members who rely on his communication.

Sensory Losses

Some traumatic brain injuries result in permanent loss of sensory functions, like taste, smell, hearing, or vision. These impairments are rated differently depending on which sense is affected. Loss of taste and smell are considered low-percentage impairments under the neurological schedule, while hearing and vision losses are rated under the miscellaneous schedule and paid out as a percentage of the full award amount.

Loss of Taste and Smell (Neurologic Schedule)

Post-concussive loss of taste and smell, especially common in frontal lobe injuries, is rated under the neurological schedule and receives a flat award.

Category	% Impairment	Award
1	3%	$7,929.96
2	3%	$7,929.96

Hearing and Vision Loss (Miscellaneous Schedule)

Though less common, hearing and vision loss can occur with moderate to catastrophic injuries, particularly if the injury involved a blow to the side of the head, a skull fracture, or inner ear trauma. Damage to the brain’s auditory or visual processing centers may also result in permanent sensory deficits. 

The following values represent 100% loss for each listed sense. Most cases receive a percentage of these amounts, depending on the severity of impairment:

Injury Type	Award Amount
Loss of one eye by enucleation (surgical removal)	$63,439.65
Loss of central visual acuity (sharpness or clarity of vision) in one eye	$52,866.42
Complete loss of hearing in both ears	$126,879.72
Complete loss of hearing in one ear	$21,146.46

Example: A worker who loses 50% of their hearing in one ear from a TBI could be awarded roughly half of the $21,146.46 maximum, around $10,573.23, in addition to any other PPD ratings tied to the brain injury, which together may provide fair compensation.

How Does L&I Handle a TBI That Falls in Multiple Categories?

Washington’s PPD system allows a single brain injury claim to be rated in multiple impairment categories, but only if each impairment is properly documented, evaluated, and submitted. L&I will not automatically combine ratings for you. It’s up to you (or your legal representative) to ensure each relevant category is pursued and supported.

• For example, a TBI that leaves a worker with cognitive dysfunction (mental rating), occasional seizures (convulsive neurologic rating), slurred speech (speech rating), and partial hearing loss (sensory rating) can qualify for four separate awards, each calculated as a percentage of its respective maximum. 
• If any one impairment is left out or unreported, L&I typically pays only for the documented portions, significantly reducing the potential settlement.
• Ratings in different categories are not mutually exclusive. L&I will combine but not add them together, creating a higher combined payout. Again, only if each rating is independently approved.

Example: An injured worker rated at 35% for mental impairment ($92,516.25), with a seizure disorder rated at 60% ($158,599.28), plus 50% hearing loss in one ear (~$10,573.23), could receive a combined PPD award.

This stacking of multiple PPD categories is central to maximizing compensation for injury victims, but it requires intentional documentation, multiple medical evaluations, and legal advocacy.

Why Mild TBIs and Concussions Still Lead to Major Settlements

Traumatic brain injuries aren’t always dramatic. You don’t have to lose consciousness or fracture your skull for a brain injury to turn your life upside down. Many mild TBIs, especially repeat concussions, lead to long-term problems with memory, focus, mood, sleep, and even personality changes. These symptoms fall under the mental category of Washington’s award schedule, which can result in significant compensation if rated correctly.

Labor and Industries doesn’t just look at the injury itself. They base awards on how much function you’ve lost and whether those impairments are permanent. Even “mild” injuries can lead to moderate or severe ratings if they affect your ability to work, manage daily tasks, or maintain relationships. Outcomes can vary significantly depending on the circumstances.

Because of this, it’s not uncommon to see claims for mild TBIs or concussions begin in the $25,000 to $50,000 range and grow larger depending on the number and type of categories affected. In a few examples, claimants have secured higher settlements when multiple impairments were properly documented.

When more than one category applies, say, mental impairment plus taste loss or hearing damage, the total settlement can rise sharply. Labor and Industries is required to pay for each separate impairment, as long as it’s backed by credible medical evidence. That’s why several factors, including timing, documentation, and proper ratings, play such a major role in determining the fair settlement.

Why You Need a Lawyer for a TBI Claim

Traumatic brain injuries are some of the most complex and misunderstood injuries in Washington’s workers’ compensation system. They don’t always show up on scans. They don’t heal in predictable ways. And most importantly, they can involve multiple, overlapping types of impairment that L&I won’t rate unless they’re documented correctly. Without legal guidance, it’s easy to miss out on major parts of your settlement. Here’s why hiring an experienced TBI lawyer is especially important in a TBI case:

• Your claim may involve multiple rating categories. Mental, convulsive, sensory, and speech impairments are all evaluated separately. If even one is overlooked or dismissed by your attending physician, your settlement amount decreases.
• L&I does not combine ratings automatically. They will not volunteer to stack awards from different categories unless your claim clearly establishes the basis for each one, and a lawyer makes sure nothing gets missed.
• You need medical opinions that L&I respects. Not all doctors understand the PPD schedule, and some may be unfamiliar with how TBI symptoms translate into award percentages. A lawyer can help you get evaluated by the right specialists and focus on proving how your TBI qualifies for compensation under L&I’s rating system.
• Your long-term symptoms may not show up right away. Many TBI-related impairments, like memory loss or emotional regulation, emerge weeks or months later. Legal representation ensures those developments are captured before your claim closes.
• A small difference in your rating can make a big difference in your compensation. With the maximum TBI awards set at $256,982.43, even a 10% change in your impairment rating could mean more than $25,000 gained or lost, depending on life expectancy and ongoing care.
• Employers or claims managers may try to close your claim early. A lawyer steps in when you’re being rushed or pressured to accept a settlement offer that doesn’t reflect the full extent of your injury.
• Your symptoms might be misdiagnosed as other conditions. If L&I attributes your cognitive changes to aging, stress, or pre-existing mental health issues, your attorney can fight to keep the focus where it belongs: on your injury and the impact of someone else’s negligence.
• You may need to challenge a low IME rating. If your impairment was minimized by an independent medical examiner, a lawyer can help you contest it with a second opinion.

FAQs – Average Traumatic Brain Injury Settlement

What counts as a TBI under Washington workers’ comp?

Any brain injury caused by a workplace accident (concussions, skull fractures, brain bleeds, loss of consciousness, or cognitive changes) can be considered a TBI. You don’t need to have been hospitalized or diagnosed on day one.

What if my symptoms didn’t show up until later?

That’s common. Many workers don’t realize they’re having memory issues, emotional changes, or other cognitive symptoms until weeks or months later. A lawyer can help reopen the claim or request additional ratings if your condition evolves.

Can I get rated under more than one PPD category?

Yes, and in TBI cases, you often should be. The schedule allows separate awards for mental, convulsive, speech, vision, hearing, smell/taste, and other impairments. But L&I doesn’t add these up automatically. You need strong documentation for each, which is why legal help matters.

Do I have to see an IME to get rated?

Not always. If your attending physician is familiar with L&I’s rating system and willing to submit the right paperwork, you may not need an Independent Medical Exam. But if you get a low IME rating or your provider won’t rate certain conditions, a lawyer can help get you a second opinion.

Can I reopen my claim later if my TBI gets worse?

Yes. Washington allows you to reopen your claim for aggravation of a condition. But there are deadlines, and you’ll need solid objective medical evidence showing your condition has worsened. Don’t wait too long. Talk to a lawyer before your window closes.
