Quick questions
What counts as a catastrophic injury
We represent the person hurt in Los Angeles County and the family member reading on their behalf, usually a spouse, a parent, or an adult child. The claim turns on what the term means in California, how a permanent injury is proved, where the money comes from, what the liens take (the repayment claims against the settlement), and the deadlines. Workers' compensation benefits and Social Security disability are separate systems.
No California statute defines a catastrophic injury for a personal injury lawsuit, and there is no separate cause of action. The elements are ordinary negligence: that the defendant was negligent, that you were harmed, and that the negligence was a substantial factor in causing the harm, as CACI No. 400 instructs the jury, resting on the duty of ordinary care in Civil Code section 1714.
The phrase does appear in California law, in the workers' compensation code. Labor Code section 4660.1, subdivision (c), bars a higher impairment rating for a psychiatric disorder arising from a physical injury, then excepts a victim of a violent act and a catastrophic injury, "including, but not limited to, loss of a limb, paralysis, severe burn, or severe head injury." That list exists to set a workers' compensation rating. It does not govern a personal injury lawsuit.
The injuries lawyers and insurance adjusters mean by the word are a short list: severe traumatic brain injury, spinal cord injury and paralysis, amputation, severe burns, permanent fractures, loss of vision or hearing, and loss of an internal organ. What they share is that the person needs something for life, and someone has to pay for it.
| What is being compared | Ordinary injury claim | Catastrophic claim |
|---|---|---|
| Legal elements | Negligence, harm, substantial factor | The same three, proved in far more depth |
| Who proves the damages | Treating doctors and the bills | Doctors, a life care planner, a vocational expert, an economist |
| The number in dispute | Past bills and lost wages | Future care and lost earning capacity, for life |
| What limits the recovery | The value of the injury | The insurance and assets that exist |
| When it can be valued | When treatment ends | When the prognosis is known, not before |
The injuries that count as catastrophic
Severity defines the category, but the proof problems belong to the injury. Each one has its own medicine, its own defense argument, and its own page.
Severe traumatic brain injury
A traumatic brain injury is damage to the brain caused by an outside force. The CDC counted 214,110 TBI-related hospitalizations in 2020 and 68,663 TBI-related deaths in 2023, more than 586 hospitalizations and 190 deaths a day. In a severe case the dispute is rarely whether the brain was hurt; it is what the person will be able to do in ten years. See our brain injury attorney page.
Spinal cord injury and paralysis
Paralysis follows damage to the cord that interrupts signals between the brain and the body. Tetraplegia affects all four limbs; paraplegia affects the legs and, depending on the level, the trunk. These are the most expensive injuries in civil litigation, and the cost data is public. See our spinal cord injury page and its guide to the lifetime cost of care.
Amputation and limb loss
A limb is lost at the scene, or a surgeon takes it days later when circulation cannot be restored. The damages problem is the prosthesis, which is never a one-time purchase. Our guide to amputation and limb loss claims covers the mechanisms, the replacement cycle, and returning to work.
Severe burns
Burns are classified by depth, and the depth decides the surgery. The National Library of Medicine's MedlinePlus page on burns describes the most serious: third-degree burns "damage or destroy the deepest layer of skin and tissues underneath." Our guide to severe burn injury claims covers grafting, scarring as damages, and the fact patterns behind most Los Angeles burn cases.
Polytrauma, and the losses that get missed
Polytrauma is injury to more than one body system at once, which is what a high-speed collision or a fall from height produces. No single diagnosis looks severe on paper; the combination is. Vision and hearing losses get missed the same way, and they decide what work is still possible.
How catastrophic injuries happen in Los Angeles
The mechanism decides who the defendants are and which policies exist. Our first question is what hit you and who owned it, because that determines the defendants and the coverage.
- Trucks and freeway collisions. Weight and speed produce the injuries that do not heal, and the trucking company (the carrier), the broker, and the shipper may each carry coverage. See truck accidents.
- Motorcycles and pedestrians. With no cage and no crumple zone, the body absorbs the whole impact. See motorcycle and pedestrian accidents.
- Construction sites. Falls from height, crushing injuries, electrocution, and equipment failures, usually with a workers' compensation claim plus a claim against someone other than the employer. See construction accidents.
- Dangerous property. Stairs, balconies, pools, unlit garages, and building fires. See premises liability and slip and fall.
- Defective products and machinery. A manufacturing defect, a design defect, or a missing warning, each its own route to liability under CACI No. 1200.
- Fatal outcomes. When the injury kills, statute decides who may bring the claim. See wrongful death.
Cal/OSHA's Census of Fatal Occupational Injuries, published April 2026, counted 419 workplace deaths in California in 2024, construction second among industries at 81, a fatality rate of 6.2 per 100,000 workers against a statewide average of 2.5. The report is at the Department of Industrial Relations. Deaths are counted; survivors with permanent injuries are not.
How we prove a permanent injury
Negligence is the failure to use reasonable care. The elements do not change because the injury is severe, and on a property case the jury gets CACI No. 1000 instead. What changes is depth: in an ordinary case the medical records are the damages evidence, and here they are only the start.
Preserving what will otherwise disappear
Spoliation is the destruction or concealment of evidence. Trucks get repaired, machines get rebuilt, and video overwrites itself on a cycle measured in days. Early on, we send preservation letters, written demands that evidence be kept, because CACI No. 204 lets a jury decide that evidence a party concealed or destroyed would have been unfavorable to it. That instruction is worth more when the letter went out in week one.
The people who prove a permanent injury
- Treating physicians. The surgeon, the physiatrist (a rehabilitation physician), and the neurologist establish what happened and what comes next.
- A life care planner. Usually a rehabilitation nurse or physician, who prices the care, equipment, medication, therapy, attendant care, and home and vehicle changes the person needs for life.
- A vocational rehabilitation expert. Establishes what work is still possible, and what it pays.
- A forensic economist. Converts a lifetime of care and lost earning capacity into a number a jury can award today.
- An accident reconstruction engineer. Establishes speeds, forces, sightlines, and what the evidence rules out.
- A human factors expert. Explains what a person could perceive and do in the seconds before impact.
Loss of earning capacity is its own item of damage, separate from lost wages. Under CACI No. 3903D the jury compares what the person could have earned without the injury to what they can still earn with it, and the instruction states that it is not necessary that the person have a work history. That sentence carries injured students, homemakers, and young workers whose tax returns understate what they were going to earn.
Two more instructions decide many of these cases. CACI No. 3927 tells the jury that a defendant who worsens a preexisting condition pays for the effect on it. CACI No. 3928 requires full damages even if the plaintiff was more susceptible to injury than a normally healthy person. Every catastrophic file draws a defense examination built around the word "degenerative," and those two instructions are the answer.
We document the life, not only the injury: the therapy session, the modified bathroom, and the people who knew the person before. CACI No. 3905A tells jurors there is no fixed standard for noneconomic damages and that they must use their judgment, and that judgment is informed by what we put in front of them.
The life care plan decides your case
A life care plan is a written projection of everything a person will need because of the injury, item by item, with a cost and a replacement interval for each: surgeries, medication, therapy, equipment, attendant care, transportation, and home modification. A planner prices it against real regional charges, and an economist reduces the total to present cash value, the lump sum today that would cover those future costs. Without one, future care is an argument; with one, it is an itemized document the defense has to challenge line by line.
California sets the standard the plan has to meet. CACI No. 3903A requires proof of "the reasonable cost of reasonably necessary medical care that [the plaintiff] is reasonably certain to need in the future." The standard is reasonable certainty, not possibility, so a plan built on what treating physicians have recommended survives cross-examination and a wish list does not.
For scale, the National Spinal Cord Injury Statistical Center publishes cost estimates by severity in its 2026 SCI Data Sheet, drawn from 38,647 people tracked through August 2025 at 31 federally funded centers. The figures are in 2025 dollars, the lifetime columns are discounted at 2 percent, and they exclude indirect losses such as wages and benefits, which the same document puts at an average of $97,787 a year.
| Severity | First year | Each later year | Lifetime, injured at 25 | Lifetime, injured at 50 |
|---|---|---|---|---|
| High tetraplegia (C1 to C4) | $1,446,827 | $251,246 | $6,419,617 | $3,528,112 |
| Low tetraplegia (C5 to C8) | $1,045,459 | $154,128 | $4,690,573 | $2,885,122 |
| Paraplegia | $705,131 | $93,409 | $3,139,165 | $2,060,139 |
| Motor functional at any level | $472,190 | $57,353 | $2,144,693 | $1,513,784 |
Those are averages for one injury type, not a valuation of anyone's case. Our guide to life care plans and future medical costs explains the table, names who writes a plan, shows how the defense attacks it, and explains how a future cost becomes a present number.
Where the money comes from
Policy limits are the maximum a policy pays for one claim or one accident. In a serious case the first policy is rarely the last, and the work is finding the rest early.
| Source | When it applies | What triggers it |
|---|---|---|
| Primary liability policy | Any at-fault driver, owner, or business | The at-fault party's own coverage |
| Excess or umbrella policy | Commercial and higher-asset defendants | Primary limits are exhausted |
| The at-fault person's employer | The person was working | Conduct within the scope of employment |
| The owner of the vehicle | Someone else was driving with permission | Vehicle Code 17150, capped by section 17151 |
| Your underinsured motorist coverage | Your own auto policy | The at-fault limits are exhausted |
| A manufacturer or seller | A defective vehicle, part, or machine | Manufacturing or design defect, or failure to warn |
| A public entity | Public property, vehicle, or employee | A written claim within six months |
| A contractor or property owner | Job sites and premises | Retained control, or a dangerous condition |
Underinsured motorist coverage is the coverage most people own and overlook. It is your own policy paying the gap when the at-fault driver's limits are smaller than your loss, and Insurance Code section 11580.2 governs it, including the rule that the coverage "does not apply to any bodily injury until the limits of bodily injury liability policies applicable to all insured motor vehicles causing the injury have been exhausted."
More than one defendant brings in a rule most families have not encountered. Under Civil Code section 1431.2, adopted by Proposition 51, each defendant's liability for noneconomic damages is several only and not joint. Several liability means each defendant pays its own percentage and no more, so one found 20 percent responsible pays 20 percent of the pain and suffering even if the others are uninsured. Economic damages are not divided that way.
Sometimes every policy in the file adds up to less than the plan. That outcome has its own strategy, covered in our guide on what happens when the insurance is not enough.
What the family keeps after liens
A medical lien is a right to be paid out of your recovery, held by a provider who treated you or a health plan that paid. Subrogation is the related right of an insurer to step into your shoes and recover what it spent. Both come out before the family sees anything, which is why a gross settlement figure is never the client's number.
California caps some of them. Under Civil Code section 3045.1 a hospital that treats an accident victim has a lien for its reasonable and necessary charges, and section 3045.4 limits what the paying party must satisfy to 50 percent of the money due under the settlement or judgment. Where Medi-Cal paid, Welfare and Institutions Code section 14124.78 bars the director, meaning the state Medi-Cal program, from recovering more than the beneficiary recovers after attorney's fees and litigation costs are deducted.
Where a person is on Medicare, or will be, the future medical part of a settlement has to be handled so that Medicare's interest is considered rather than ignored. When coverage runs out, lien reduction is one of the few remaining ways to raise what the family keeps.
How long you have to file
| Who the defendant is | Deadline | Source |
|---|---|---|
| A private person or business | 2 years from the injury | Code of Civil Procedure 335.1 |
| A city, county, or state entity | 6 months to present a written claim | Government Code 911.2 |
| A public entity that rejected the claim | 6 months from that written notice to sue | Government Code 945.6 |
| A public entity that sent no written rejection | 2 years from when the claim accrued | Government Code 945.6 |
| Your own underinsured motorist claim | 2 years from the crash to sue or demand arbitration | Insurance Code 11580.2(i) |
The sources are Code of Civil Procedure section 335.1, Government Code section 911.2, and section 945.6. A case filed in the Central District of Los Angeles goes to an Independent Calendar department at the Stanley Mosk Courthouse, a change the Superior Court announced on December 14, 2023 and put into effect on January 8, 2024.
Why these cases take longer
A catastrophic case cannot be valued until the medicine settles. Until a physician can say what function returns and what does not, no life care planner can price the future and no economist can total it. Settling before maximum medical improvement means guessing low on the largest part of the case.
The first offer usually arrives while the client is still in rehabilitation. That is a negotiating position, not a valuation, made early because early is when the file looks smallest.
Waiting has a cost, and families in this position are usually out of income. That is a conversation about liens, medical financing, and available coverage, not a reason to take the first offer.
When the injury is not catastrophic
Many serious injuries are not catastrophic, and that is good news for the person hurt. Four situations change the answer:
- The injury is expected to resolve. A fracture that heals is an ordinary claim, and adding experts to it costs the client money without adding value.
- The only defendant is your employer. Workers' compensation is the exclusive remedy under Labor Code section 3602, with three narrow exceptions: a willful physical assault by the employer, fraudulent concealment of an existing injury, and a defective product the employer made and sold to a third party. If the employer never secured coverage, Labor Code section 3706 opens a direct action for damages.
- The at-fault party carries minimum limits and owns nothing. The case is still worth pursuing, but the work moves to underinsured motorist coverage and lien reduction.
- The deadline has passed. A missed six-month government claim is sometimes revived by an application for leave to present a late claim. That is worth a call the same week you learn of the missed date.
How we work a catastrophic case
- 1Get the treatment right first
The person has to be in front of the right doctors, with the imaging ordered. Everything else is built on that record.
- 2Preserve the evidence
Preservation letters go to the trucking company, the contractor, and anyone holding video. Vehicles and equipment are inspected before they are repaired or scrapped.
- 3Find every policy
The primary policy, any excess or umbrella policy above it, the employer, the vehicle owner, the contractor, the manufacturer, and your own underinsured motorist coverage.
- 4Build the future, not only the file
A life care planner, a vocational rehabilitation expert, and an economist, brought in once the medical picture is stable enough for their work to hold up.
- 5Handle the adjuster
We take the calls and the recorded statement request. The family should be at the hospital, not on the phone with someone building a defense file.
- 6Reduce the liens before the money moves
Hospital, health plan, and public benefit claims are negotiated down before disbursement, when the money is paid out. The net number is the one that pays for care.
Two of our results involved the longest treatment: $6,300,000 for a man sideswiped on the freeway by a semi-truck, whose concussion required extensive treatment with a neurologist, and $1,250,000 for a man rear-ended by a texting driver on the job, whose herniated disc required surgery. Neither client was paralyzed and neither lost a limb. We publish the cases we have, on our case results page.
Truck collision, concussion
Sideswiped on the freeway by a semi-truck. Settled on the eve of trial.
Rear-end crash, herniated disc
Hit at a stoplight by a texting driver on the job. Back surgery, then a real settlement.
Prior results do not guarantee a similar outcome. Every case depends on its own facts, injuries, and insurance coverage. Amounts shown are gross recoveries before attorney's fees, costs, and medical liens.
Talk to a catastrophic injury lawyer
An injury is catastrophic when it permanently changes what a person can do, earn, and need. California gives you no separate claim for it and no threshold to cross. It gives you the same negligence case carrying a far heavier damages burden, on a two-year deadline that shrinks to six months against a public entity.
Keep every appointment and follow the treatment plan. Write down this week what the person could do before and cannot do now. Give the other side no recorded statement. Find out what insurance exists before anyone repairs the truck.
