Average concussion / mild tbi settlement amounts
Typical range (2026)
$20K – $125K
Severe cases with surgery or permanent impairment can reach $1 million or more.
Concussions are classed as mild traumatic brain injuries, but their effects — memory problems, headaches, mood changes, sensitivity to light — can persist for months or years (post-concussion syndrome). Insurers underpay these claims because symptoms don't show on standard imaging; documentation is everything.
Concussion / Mild TBI settlement amounts by severity
Averages hide more than they reveal — a handful of catastrophic outcomes pull every published average upward. Find the band that matches your own treatment instead.
| Severity | What it looks like | Typical range |
|---|---|---|
| Brief concussion, full recovery | Symptoms resolving within two to four weeks, no imaging findings, no lost work beyond a few days. | $15K–$40K |
| Prolonged recovery | Symptoms lasting one to three months, referral to a concussion clinic, restricted work or screen time. | $35K–$90K |
| Post-concussion syndrome | Symptoms past three to six months, neuropsychological testing showing measurable deficits, vestibular therapy. | $85K–$350K |
| Permanent cognitive deficit | Documented lasting impairment affecting employment, requiring accommodation or career change. | $300K–$1.5M |

Concussion / Mild TBI symptoms people report after a crash
- Headaches that persist for weeks after the crash
- Memory lapses and difficulty finding words
- Trouble concentrating or reading for long
- Light and noise sensitivity
- Sleep disruption and daytime fatigue
- Irritability, anxiety, or personality changes family members notice first
How treatment changes what the claim is worth
Each step up this ladder adds documented cost and, more importantly, moves the claim further from the insurer's soft-tissue formula.
Emergency CT scan
Rules out bleeding. A normal CT is expected in concussion and does not mean nothing happened — but the insurer will present it as if it does.
Documented symptom tracking in the first weeks
Concussion claims live or die on contemporaneous records. Symptoms reported at week two carry weight that the same symptoms recalled at month six do not.
Neurology or concussion-clinic referral
Specialist involvement moves the claim out of the soft-tissue bucket and signals that the injury was taken seriously.
Neuropsychological testing
The highest-leverage step in the entire claim. Standardized testing produces objective deficit scores an adjuster cannot wave away.
Vocational assessment
Where cognitive deficits affect work, a vocational expert translates them into a lost-earning-capacity figure — usually the largest number in the file.
What the insurer will argue about your concussion / mild tbi claim
None of these are unusual. Knowing which one is coming is most of the defense against it.
“The CT scan was normal”
Standard CT and MRI are not designed to detect the diffuse axonal injury underlying most concussions. A normal scan is the expected result. Adjusters use it anyway, and the counter is neuropsychological testing, which measures function rather than structure.
Attributing symptoms to stress or depression
Concussion symptoms overlap heavily with anxiety and depression, and the carrier will argue you are simply upset about the crash. Treatment by a provider who specializes in brain injury, rather than general primary care, makes this argument much harder to sustain.
Mining prior concussion history
A high-school sports concussion will be produced as the real cause. Prior concussions actually increase vulnerability to a new one — the medical literature supports aggravation, not exclusion.
Testing you before symptoms mature
An early independent medical examination, scheduled while you are still improving, produces a snapshot that undersells the eventual permanent deficit.
What moves your number
- Neuropsychological testing results
- Duration of post-concussion symptoms
- Time missed from work or school
- Prior concussion history
Proving a concussion / mild tbi claim
Documentation specific to this injury. Concussion claims typically take 8 to 18 months, longer than the injury itself, because value cannot be assessed until it is clear whether symptoms will resolve. Post-concussion syndrome claims routinely run two years or more.
Emergency record noting loss of consciousness, confusion, or amnesia
Neuropsychological test battery with standardized scores
Statements from family or coworkers describing observed changes
Employer documentation of accommodations, errors, or reduced hours
Symptom diary kept from the first week forward
What to do in the first two weeks
These apply to every injury claim, and each one is a mistake insurers count on.
Get treated within 72 hours, and do not skip visits
Treatment delay and gaps in care are the two most common reasons claims get discounted. If you have to pause treatment for money, work, or childcare, tell the provider so the reason appears in the chart rather than reading as recovery.
Photograph everything while it is fresh
Both vehicles from multiple angles, the scene, road conditions, skid marks, traffic controls, and your visible injuries as they develop. Bruising often looks worse on day three than on day one — photograph it again.
Keep a dated symptom journal
Pain scores, sleep disruption, and specific activities you could not do. Contemporaneous notes carry weight that a recollection twelve months later does not, and they are what make non-economic damages concrete.
Document work impact through your employer
A letter confirming missed shifts, modified duty, or lost overtime turns lost income from an assertion into a provable number.
Decline the early recorded statement
You are not obligated to give a recorded statement to the other driver's insurer. Early statements are taken before symptoms peak and are quoted back for the life of the claim.
Report every symptomatic area at the first visit
Injuries that hurt less at first get mentioned later, and the delay becomes the insurer's causation argument. List everything that hurts, even mildly.
How long a settlement actually takes
Six phases, and the first one is the longest. Nothing can be valued until treatment ends.
Treatment
Weeks to many monthsNothing can be valued until your doctor says you have stopped improving — maximum medical improvement. Settling before that point means paying for your own future care.
Demand package
2 to 6 weeks after treatment endsRecords, bills, wage documentation, and a written demand go to the adjuster. Assembling complete records from every provider is usually what takes the time.
Insurer review
1 to 8 weeksThe adjuster reviews the file, often runs it through claims-evaluation software, and sets an authority range. Complex or disputed claims go to a supervisor or a committee.
Negotiation
2 weeks to several monthsOffers and counters. Straightforward claims resolve in a handful of exchanges; disputed liability or serious injury can take many rounds, and sometimes a lawsuit filing to move.
Release and paperwork
Days to 2 weeksYou sign a release ending the claim permanently. Read it — a broad release can extinguish claims against parties you did not intend to release.
Payment and disbursement
2 to 6 weeksThe check goes to your attorney's trust account. Liens and medical providers are paid first, then fees and case costs, then the balance reaches you. Many states require the insurer to pay within roughly 30 days of the signed release.
Concussion / Mild TBI settlement questions people ask most
The questions people actually search for on this topic, answered in full.
What is the average settlement for a concussion from a car accident?
Published ranges cluster around $20,000 to $100,000 for mild traumatic brain injuries with recovery, rising into the hundreds of thousands where post-concussion syndrome persists or earning capacity is affected. The gap between a resolved concussion and a lasting one is roughly a factor of ten.
How much is post-concussion syndrome worth?
Claims with documented post-concussion syndrome past six months commonly settle between $85,000 and $350,000, and considerably higher when cognitive deficits change what work you can do. Neuropsychological testing is effectively required to reach the upper part of that range.
Can you have a concussion with a normal CT scan?
Yes — that is the norm. CT is designed to find bleeding and skull fracture, not the microscopic axonal injury that causes concussion symptoms. Insurers lean hard on normal imaging, which is precisely why functional testing matters so much in these claims.
How long does a concussion claim take to settle?
Typically 8 to 18 months. Attorneys generally wait for a full neurological prognosis rather than settling early, because a concussion that turns out to be permanent is worth many times one that resolves — and there is no way to reopen a signed release.
What proof do you need for a concussion claim?
The strongest file combines an emergency record noting confusion or memory loss, early and consistent symptom documentation, a specialist's diagnosis, and neuropsychological testing showing measurable deficits. Family and coworker statements about observed changes carry real weight, because the person with the injury is often the last to notice.
Do concussion settlements cover lost earning capacity?
They can, and in serious cases that is the largest component. It requires a vocational expert or economist to connect documented cognitive deficits to a specific reduction in what you can earn over your remaining working life.
Is a concussion considered a traumatic brain injury?
Yes. A concussion is classified medically as a mild traumatic brain injury. The word 'mild' describes the initial presentation, not the outcome — a meaningful minority of concussions produce symptoms lasting a year or more.
What if my concussion symptoms started days after the crash?
Delayed onset is common and does not defeat the claim, but it does hand the insurer an argument. Report the symptoms to a doctor as soon as they appear, and make sure the record connects them to the collision date rather than describing them as new and unexplained.
Fees, taxes and what you actually take home
The questions people actually search for on this topic, answered in full.
How much does a personal injury lawyer take from a settlement?
Contingency fees typically run 33% to 40%. The common structure is one third if the case settles before a lawsuit is filed, rising to 40% once litigation begins or the case approaches trial. Case expenses — filing fees, records, expert reports — are usually deducted on top of the fee rather than out of it, so ask specifically which structure the agreement uses.
Are personal injury settlements taxable?
Compensation for physical injury or physical sickness is generally not taxable federally. Portions allocated to lost wages, punitive damages, and interest generally are, and previously deducted medical expenses can be taxable when reimbursed. How the settlement is allocated among those categories has real consequences, so it is worth addressing before the documents are signed rather than at tax time.
How much of my settlement do I actually take home?
The order of payment is liens and medical providers first, then attorney fees and case expenses, then you. On a $100,000 settlement with a one-third fee, $4,000 in costs, and $15,000 in medical liens, the net is roughly $48,000 — and lien negotiation is frequently where the largest gains are available, because providers often accept substantial reductions.
How long does it take to get paid after a settlement is signed?
The insurer typically issues the check within two to four weeks of receiving the signed release, and most states require payment within a reasonable period commonly understood as 30 to 45 days. Disbursement to you then depends on how quickly liens are resolved, which can add several weeks.
Should I accept the insurance company's first offer?
Usually not. Industry analysis consistently places first offers at roughly half of a claim's fair value, and adjusters are evaluated in part on savings against reserves. Cases involving a genuine lowball frequently resolve for several times the opening number once the file is properly documented — but the first offer is also final if you accept it, because the release closes the claim permanently.
Do I have to repay my health insurance from a settlement?
In most cases yes. Health insurers, Medicare, Medicaid, and hospitals hold subrogation or lien rights against injury recoveries. Those liens are frequently negotiable — sometimes substantially — and reducing them raises your net recovery dollar for dollar without any further negotiation with the insurer.
Concussion / Mild TBI settlements by state
State law changes what an identical injury is worth. Filing deadlines, fault rules, no-fault thresholds, damage caps, and local verdict climates all move the number — sometimes by more than the injury itself does.
