One Number Decides What Your Case Is Worth

At some point in a serious California comp claim, your injury gets converted into a percentage. Twelve percent. Thirty-one percent. Whatever the number is, it will determine how many weeks of permanent disability you’re paid, and it will anchor every settlement conversation that follows.

Most injured workers see that number for the first time on a piece of paper, with no idea how it was constructed or that it could have been constructed differently. Understanding how it’s built is the difference between accepting a rating and evaluating one.

It Starts at Permanent and Stationary

Nothing gets rated until you’re permanent and stationary — meaning your condition has stabilized and isn’t expected to materially improve with further treatment. In more current usage you’ll also see “maximum medical improvement.”

Two things about that milestone are worth knowing.

First, it is a medical opinion, not a fact, and doctors can reach it too early. A treating physician who declares you permanent and stationary while you’re still actively improving locks in a rating that understates where you would have ended up.

Second, it changes your benefits. Temporary disability generally ends at permanent and stationary, and the case moves into its permanent phase. If you’re surprised to be declared stable, that’s worth raising immediately rather than after the report is final. Our article on temporary versus permanent disability covers the distinction in more detail.

How the Rating Gets Built

California builds a permanent disability rating in layers. Each one can be argued.

1. Whole person impairment

The evaluating physician assigns an impairment rating under the AMA Guides to the Evaluation of Permanent Impairment, Fifth Edition — the standard California uses. This is a clinical measurement: range of motion, strength, neurological findings, diagnosis-based criteria depending on the body part.

This is the foundation, and errors here propagate through everything downstream. An incomplete examination, a body part left unaddressed, or a measurement taken on a good day produces an impairment number that is wrong before any adjustment is applied.

2. Statutory modifier

The impairment is adjusted by a statutory factor. For injuries on or after January 1, 2013, California applies a flat modifier in place of the older future-earning-capacity adjustments used for earlier dates of injury.

3. Occupational adjustment

Your occupational group then adjusts the figure. The same shoulder impairment means something very different for a framing carpenter than for a dispatcher, and the schedule accounts for that.

This step is more contestable than it looks. Occupational group assignment depends on what you actually did, not on your job title. “Maintenance worker” covers an enormous range. If your group number was assigned from a title rather than a real description of your duties — the weights, the climbing, the tools, the conditions — the adjustment can be materially wrong.

4. Age adjustment

Your age at the time of injury adjusts the rating, on the reasoning that the same impairment affects remaining working life differently at 28 than at 58.

5. Apportionment

Finally, apportionment divides the disability between industrial and non-industrial causes. Only the work-related share is compensable.

This is where the largest reductions happen, and where cases are most often quietly lost. An evaluator who attributes half your spinal disability to degenerative change has cut your award in half in a single sentence — a sentence that may or may not be well supported.

What the Percentage Actually Buys

The final percentage converts to a number of weeks of permanent disability payments under the statutory schedule, paid at a weekly permanent disability rate.

The relationship is not linear — higher percentages yield disproportionately more weeks, so a few points of rating can be worth considerably more than they appear. That’s precisely why arguing about what looks like a small difference in impairment is often worth doing.

At 100%, the disability is permanent total, which carries lifetime payments.

Where Ratings Go Wrong

In practice, the recurring problems are these:

• An incomplete evaluation. Body parts you complained about that never made it into the report, because they weren’t in the referral or you didn’t raise them clearly.
• A thin job description. The occupational adjustment built on a title rather than actual duties.
• Unchallenged apportionment. A conclusory statement that half your disability is degenerative, accepted because nobody pushed on it.
• Premature permanent and stationary status. Rated while still improving.
• Psychiatric or sleep components never addressed. Where legitimately present and properly supported, these can add to a rating — and they are routinely omitted.
• Nobody explaining the report to the worker. The rating arrives, it’s incomprehensible, and it goes unquestioned because it looks official.

Every one of these is addressable — before the report becomes the settled record. Afterward, it’s much harder.

Challenging a Rating

A rating you believe is wrong isn’t necessarily final. Depending on the posture of your case, the avenues include supplemental reports from the evaluating physician addressing what was missed, a deposition of the evaluator, cross-examination, and in some circumstances a further evaluation.

All of these are time-limited and procedurally technical, which is the real argument for getting advice as soon as a report you disagree with arrives — not months later when the case is being settled.

Frequently Asked Questions

How is permanent disability calculated?

A physician assigns whole person impairment under the AMA Guides, Fifth Edition. That figure is adjusted by a statutory modifier, your occupational group, and your age, then reduced by any apportionment.

Does my percentage mean I lost that much of my body?

No. It’s a scheduled measure that converts to weeks of payments, not a statement about your body or how disabled you feel.

Why did my rating drop because of apportionment?

Because only the work-related share of your disability is compensable. Whether the apportionment opinion is properly supported is a separate — and contestable — question.

Can I be rated for more than one body part?

Yes, multiple impairments can be combined under the schedule. Making sure every affected body part is actually evaluated is one of the most valuable things you can do before the exam.

What if I’m rated but still can’t work?

A rating short of 100% doesn’t mean you’re employable in practice. Depending on your circumstances, a job displacement voucher, vocational evidence, or Social Security Disability may be relevant.

Have the Report Reviewed Before It Becomes Final

A permanent disability rating is built from a medical report, a job description, and an apportionment opinion. Each of those can be incomplete, and each is far easier to fix before it hardens into the record everyone settles from.

Two Doors, and They Don’t Lead to the Same Place

Eventually most California workers’ compensation cases arrive at a settlement discussion. And when it arrives, the injured worker is usually presented with a number and very little explanation of the structure behind it.

There are two basic ways to resolve a California comp case, and the difference between them is not primarily about the dollar amount. It’s about what happens to your medical care afterward.

• Compromise and Release (C&R) — a lump sum. The case closes, generally including future medical treatment.
• Stipulations with Request for Award (“Stips”) — agreed permanent disability paid over time, with future medical care for the injury generally remaining open.

Understanding which one you’re being offered is the difference between an informed decision and a signature.

Compromise and Release: Money Now, Door Closed

In a C&R, the parties agree on a single sum resolving the claim. You receive a lump payment, and the case is closed — ordinarily including your right to future medical treatment for that injury.

The genuine advantages:

• Certainty and finality. The case ends. No more appointments coordinated through an adjuster, no more authorization fights, no more surveillance.
• Control over your own care. You choose your doctors and your treatment on your own terms, outside the utilization review machinery.
• A meaningful amount of money at once, which for a household that has been running on two-thirds pay can matter enormously.
• A clean break from the employer relationship, which some workers value more than any of the above.

The cost, and it’s the whole thing: future medical care for that injury becomes yours to arrange and pay for. If you need an injection series in six years, or the hardware in your knee fails in twelve, that’s on your own insurance and your own money.

So the central question in evaluating a C&R is not “is this a lot of money?” It’s “is this enough money for the medical care I’m actually going to need for the rest of my life?” — which requires an honest projection of your medical future, not an optimistic one.

One Complication Worth Knowing About

If you’re a Medicare beneficiary, or have a reasonable expectation of becoming one, federal rules require that Medicare’s interests be considered when settling a claim that closes future medical care. In practice this often means a Medicare Set-Aside — a portion of the settlement earmarked for injury-related care that Medicare would otherwise cover.

This is a technical area with real consequences for how much of the settlement you can actually spend, and it should be addressed before you agree to a number, not after.

Stipulations: Payments Over Time, Medical Stays Open

With Stips, the parties agree on the facts — most importantly your permanent disability rating — and a judge issues an award based on that agreement.

The advantages:

• Future medical care generally remains open for treatment reasonably required to cure or relieve the effects of the injury. For a worker facing a probable future surgery, this can be worth far more than any lump sum on the table.
• You can generally petition to reopen for new and further disability within five years of the date of injury if your condition worsens.
• Steady payments over time, which some households manage better than a lump sum.

The tradeoffs:

• You stay in the system. Treatment still runs through utilization review and network rules, with all the friction that implies.
• No lump sum. Payments arrive on a schedule.
• The relationship continues with the carrier, and so can the disputes.

How to Actually Think About the Choice

Set the dollar figure aside for a moment and work through these:

What does your medical future realistically look like? A soft-tissue injury that resolved is a different proposition from a fused spine or a knee with hardware in it. The more future treatment you’re likely to need, the more open medical care is worth — and the more skeptical you should be of a lump sum that closes it.

Do you have other health coverage? A worker with solid group coverage through a spouse is in a different position than one with none.

How stable is your condition? If there’s a real chance you get worse, the ability to reopen within five years has value.

What’s the money actually for? A lump sum used to eliminate debt or fund retraining is different from one that covers six months of expenses and disappears.

How much do you want out? This is a legitimate factor, not a soft one. Some workers do genuinely better closing the file and moving on, and that has real value even when the arithmetic is close.

A Judge Has to Approve It — but Don’t Rely on That

Every California workers’ compensation settlement requires approval by a workers’ compensation judge, who reviews it for adequacy and can reject a settlement that shortchanges the injured worker.

That’s a meaningful safeguard, and it is not a substitute for representation. A judge reviewing a settlement is working from the record in front of them. If the record understates your permanent disability — because the evaluation was thin, or your job duties were never properly described, or apportionment went unchallenged — then a settlement consistent with that record can be approved as adequate while still being far less than your case was worth.

The safeguard protects against unfairness relative to the record. It does not protect against a record that was built badly.

Frequently Asked Questions

What’s the main difference between a C&R and Stips?

A C&R is a lump sum that generally closes future medical care. Stips pay permanent disability over time and generally keep future medical open.

Can I get a lump sum and keep my medical open?

That’s not the standard structure of either resolution, though case-specific arrangements exist. Be cautious of any description of a settlement that sounds like it gives you both without tradeoffs.

Can I reopen my case later?

After Stips, a petition to reopen for new and further disability is generally available within five years of the date of injury. A C&R ordinarily closes the case permanently.

How long do I have to decide?

Settlement offers aren’t usually subject to a hard statutory deadline, but your underlying claim is subject to strict time limits. Don’t let an offer sit indefinitely without advice.

Is the settlement taxable?

Workers’ compensation benefits are generally not taxable as income, though interactions with Social Security and other benefits can be complicated. Confirm with a tax professional about your specific circumstances.

Before You Sign Anything

A settlement is the one moment in a comp case that can’t be undone. Everything else — a bad report, a denied treatment request, a lowball rating — can be worked on. A signed and approved Compromise and Release generally cannot.

Kim LaValley and Kyle Adamson have evaluated settlement offers for injured workers across Nevada County, Placer County, and the Sierra foothills for decades. If there’s a number in front of you, call 530-362-7188 before you sign it. Reviewing an offer costs nothing.

There Was No Single Moment

Most people assume a workers’ compensation claim requires an accident — a fall, a crush, a moment you could point to on a calendar. So when a framer’s shoulders give out after eighteen years, or a nurse’s back finally stops tolerating patient transfers, or a mill worker realizes he’s been asking people to repeat themselves for a decade, the thought often isn’t I have a claim. It’s I’m getting old.

California law disagrees. Injuries that build up over time are covered, and they have their own name: cumulative trauma.

What Counts as Cumulative Trauma

Labor Code section 3208.1 defines a cumulative injury as one occurring from repetitive mentally or physically traumatic activities extending over a period of time, the combined effect of which causes any disability or need for medical treatment.

Unpack that and you get three elements: repeated activity, over time, whose combined effect causes disability or the need for treatment. No single traumatic event is required. The work itself, done long enough, is the injury.

Conditions commonly handled as cumulative trauma include:

• Spine and joint injuries from years of lifting, bending, climbing, or vibration
• Shoulder and rotator cuff damage from overhead work
• Knee deterioration from kneeling, squatting, and stairs
• Carpal tunnel and other repetitive strain injuries of the hands and wrists
• Hearing loss from prolonged noise exposure
• Respiratory conditions from dust, smoke, or chemical exposure over time
• Psychiatric injury from prolonged workplace stress, which carries additional statutory requirements

In this part of California that list maps onto real jobs: logging and mill work, construction and framing, heavy-equipment operation, road crews, ski-resort maintenance, casino and hospitality work, agriculture in the valley, and healthcare.

The Hardest Question: What’s the Date of Injury?

Every workers’ compensation deadline runs from a date of injury. For a fall, that’s easy. For an injury that developed across fifteen years, it’s the central legal question in the case.

Labor Code section 5412 supplies the answer. The date of injury for a cumulative trauma is the date upon which the employee first suffered disability and either knew, or in the exercise of reasonable diligence should have known, that the disability was caused by their present or prior employment.

Two elements, and both must be present:

1. Disability — not merely symptoms. Generally this means compensable lost time or an impairment of earning capacity, not simply that your back had been aching for years.
2. Knowledge — you knew or reasonably should have known the disability was work-related.

This matters enormously, and usually in the injured worker’s favor. Aching through a decade of shifts without missing work and without anyone connecting it to your job does not necessarily start the clock. The clock starts when disability and knowledge arrive together — which is often when a doctor first tells you the condition came from your work.

That is also why “I waited too long” is frequently wrong. Workers talk themselves out of viable claims on a mistaken assumption about when their date of injury was. It is worth having someone actually apply section 5412 to your facts before concluding you’re out of time.

The corollary: once you do have both elements, the deadlines are real and short. The moment a physician tells you your condition is work-related is the moment to get advice, not to wait and see.

Apportionment: the Fight You Should Expect

Every cumulative trauma case eventually arrives at the same argument from the other side: this is just degeneration. This is age. This would have happened anyway.

Apportionment divides your disability between industrial causes (the work) and non-industrial causes (pre-existing conditions, prior injuries, degenerative disease, aging). Only the industrial share is compensable, so apportionment directly reduces the award.

Here’s the thing worth understanding: the presence of degenerative change is not the question. Nearly every adult over forty has degenerative findings on imaging. Plenty of people have them with no disability at all. The real question is how much of your current disability is attributable to your work — and that is a medical opinion, built on your job history, your exposure, and your clinical course.

Which means it can be developed properly, or developed badly. An evaluator who receives a thorough job description — actual weights, actual repetitions, actual years, actual conditions — reaches a different conclusion than one handed a job title and a stack of imaging. Getting that record right before the evaluation is far more effective than arguing about the report afterward.

If You Think This Describes You

1. Tell your doctor about your work. In detail. Many cumulative trauma claims are never identified because nobody ever asked what the patient does for a living.
2. Write down your job history — employers, dates, and what the work physically involved. Years later, this is hard to reconstruct and enormously valuable.
3. Report it, even without an accident. You can file a claim for a cumulative injury. The absence of an incident report is not a bar.
4. Don’t self-diagnose the deadline. Section 5412 is more favorable than most people assume, and getting it wrong in either direction is costly.
5. Get advice promptly once a doctor links it to your work. That’s typically the moment the clock has meaning.

Frequently Asked Questions

What is a cumulative trauma injury?

An injury caused by repetitive traumatic activities over a period of time whose combined effect causes disability or the need for medical treatment, under Labor Code section 3208.1. No single accident is required.

How is the date of injury determined?

Under Labor Code section 5412, it’s when you first suffered disability and knew or should have known it was work-related. Both elements must be present.

Can I still file after leaving the job?

Possibly. Because the date of injury depends on when disability and knowledge coincided rather than your last day worked, a claim can still be timely. It’s fact-specific — get advice quickly rather than assuming either way.

What if I worked for several employers doing the same work?

Cumulative trauma claims can involve multiple employers and insurers over the exposure period, with liability allocated among them. That complexity is between the carriers; it shouldn’t stop you from filing.

Will they blame my age?

Expect apportionment to be argued. The answer isn’t that degeneration doesn’t exist — it’s establishing how much of your actual disability came from your work.

Find Out Before You Talk Yourself Out of It

The most common way a cumulative trauma claim dies is that the worker decides on their own that it’s just age, or that too much time has passed, and never asks.

Kim LaValley and Kyle Adamson have handled California workers’ compensation claims for decades throughout Nevada County, Placer County, and the Sierra foothills, including injuries that built up over a career rather than happening in a moment.

The First Thing People Ask After Getting Hurt

You’ve had the same doctor for twelve years. She knows your history, she knows your back, and she’s the person you’d call about anything else. Then you hurt yourself at work, and you’re told to go to an occupational clinic you’ve never heard of, to see a physician who has thirteen minutes for you.

The question is immediate and completely reasonable: can’t I just see my own doctor?

In California, the honest answer is: usually not — unless you took a specific step before you got hurt. But the picture has more room in it than most injured workers are told, and knowing where the room is matters.

The Default: Your Employer Directs Early Care

If you did nothing in advance, your employer or its claims administrator generally controls your medical treatment at the start of the claim — typically the first 30 days — and will send you to a provider of its choosing.

Beyond that initial period, the controlling question is whether your employer has a Medical Provider Network.

An MPN is a group of physicians the employer or insurer has assembled to treat work injuries. Where a valid MPN applies, your treatment generally has to come from within that network. Most substantial California employers have one.

Two things about MPNs are worth being clear-eyed about. They are not inherently a scam — plenty of competent physicians participate. But they are assembled by the party paying the claim, and the incentives are not neutral. Which is exactly why the escape hatch below is valuable.

Predesignation: the Step Almost Nobody Takes

California lets you name your own physician in advance to treat a future work injury. It’s called predesignation, and a validly predesignated personal physician may treat you regardless of any MPN — which generally extends to specialists your physician refers you to as well.

It’s a genuinely powerful right. Almost nobody uses it, because almost nobody hears about it until after they’re hurt, at which point it’s too late.

To predesignate, these conditions generally must be met before the injury:

1. Written notice to your employer identifying your personal physician — provided before the injury occurs.
2. You have health care coverage for nonoccupational injuries and illnesses on the date of injury.
3. Your physician agrees in advance to be predesignated, documented before the injury.
4. The physician is your regular personal physician — the doctor who has previously directed your medical treatment and retains your records and history.

The Division of Workers’ Compensation provides DWC Form 9783 for this. Using the form isn’t strictly required, but it’s recommended, and it removes any argument later about whether the requirements were met.

If you are reading this and are not currently injured, this is the single most useful paragraph on this page. Ask your doctor whether they’ll agree, complete the form, give it to your employer, and keep a dated copy for yourself. It costs nothing and takes fifteen minutes, and it is worthless the day after you get hurt.

Personal Chiropractor or Acupuncturist

California also allows an employee to notify the employer in advance of a personal chiropractor or acupuncturist, which permits switching to that provider after the initial treatment period. The rules differ from physician predesignation, including limits on chiropractor visits and on serving as treating physician after a cap is reached.

You Can Change Doctors Inside the Network

Suppose you didn’t predesignate — which describes most people — and you’re stuck with an MPN physician you don’t trust. You are not actually stuck.

You can change treating physicians within the MPN. The network is a list, not a single assigned doctor. You can review the roster and select a different provider, and you don’t need the adjuster’s permission to prefer another doctor in the network.

If your disagreement is about diagnosis or treatment rather than bedside manner, the MPN process also gives you the right to a second opinion, and then a third opinion, from other physicians in the network. If the dispute persists after that, it can move to independent medical review.

Injured workers under-use these rights dramatically. A treating physician who minimizes your symptoms, rushes your exam, or declares you permanent and stationary before you feel anywhere near stable is going to shape your permanent disability rating and your entire case. Changing doctors early is far easier than repairing a bad record later.

When the MPN May Not Apply at All

An MPN only controls if it’s valid and properly noticed. Some situations where the picture changes:

• Your employer has no MPN. Then after the initial period, your choice of treating physician is considerably broader.
• You were never properly notified of the MPN. Employers have notice obligations, and failures can affect whether the network can be enforced against you.
• The claim was denied. If the employer denies your claim outright, the analysis of who directs treatment changes.
• Emergency care. Emergency treatment is not restricted by network rules — if you’re seriously hurt, go to the nearest emergency room and sort out the paperwork afterward.
• No appropriate specialist within reasonable geographic access. Access standards apply, which matters in rural Nevada County and the Tahoe basin where the nearest in-network specialist may be a long drive.

That last point deserves emphasis locally. If you live in Nevada City, Downieville, or Truckee and the network’s nearest orthopedist is in Sacramento, network access standards are a real issue and worth raising rather than absorbing. Note also that travel to authorized treatment is reimbursable at 72.5 cents per mile for travel on or after January 1, 2026.

Frequently Asked Questions

Can I see my own doctor for a work injury?

Generally only if you predesignated in writing before the injury and met the other requirements. Otherwise, treatment usually has to come from the employer’s Medical Provider Network.

Is it too late to predesignate now that I’m hurt?

Yes, for this injury — predesignation must be in place before the injury occurs. It’s still worth doing going forward.

Can I switch to a different doctor in the MPN?

Yes. You can select another physician from the network roster, and you can request second and third opinions within the network if you disagree about diagnosis or treatment.

What if I go outside the network anyway?

Treatment obtained outside a validly applicable MPN may not be paid for by the claims administrator, and it can complicate your case. Get advice before doing it rather than after.

Can my regular doctor at least review what the comp doctor said?

Nothing stops you from discussing your condition with your own physician using your regular health coverage. What’s restricted is who directs and bills the industrial treatment.

If Your Treating Doctor Isn’t Listening

The treating physician’s reports drive your temporary disability, your treatment authorizations, your work restrictions, and ultimately your permanent disability rating. A doctor who isn’t documenting your actual condition is a problem that compounds every month it goes unaddressed.

Medical control rules depend on your employer’s network, the notices you received, and what you did before your injury. For advice about your situation, speak with a workers’ compensation attorney. Authoritative source material: California Division of Workers’ Compensation; 8 CCR § 9783.

A Different Set of Rules for the People Who Run Toward It

Most injured Californians on workers’ compensation take a significant pay cut. Temporary disability replaces about two-thirds of average weekly wages, and it’s subject to a statutory ceiling — which for 2026 is $1,764.11 per week.

For a worker earning well above that cap, the drop is steep and immediate.

California treats certain public safety employees differently. Under Labor Code section 4850, an injured firefighter, police officer, or sheriff’s deputy is entitled to a leave of absence at full salary — not two-thirds, and not subject to the temporary disability cap — for up to one year.

In a region served by CAL FIRE, the Nevada County and Placer County Sheriff’s Offices, and the police departments of Grass Valley, Nevada City, Truckee, and Auburn, this is not a niche provision. It’s the rule that governs a large share of the serious work injuries around here.

Who Section 4850 Covers

The statute applies to specified public safety classifications rather than to public employees generally. Covered groups include:

• City police officers and county sheriffs and deputy sheriffs
• Firefighters
• Certain other city, county, and district peace officers
• California Highway Patrol officers
• Lifeguards employed by a county, city, or district

Eligibility generally requires regular, full-time employment, and the disability must arise from a job-related injury or illness. Notably, there is no minimum length-of-service requirement — a deputy hurt in their first month is covered the same as one with twenty years in.

Because the statute works by listed classification, whether a particular position qualifies is not always obvious from the job title alone. Dispatchers, corrections staff, seasonal fire personnel, and district employees sit near the boundaries, and the answer depends on the specific classification and employer. If you’re near that line, it’s worth confirming rather than assuming.

What the Benefit Actually Provides

The core of section 4850 is straightforward: your salary continues during the period of temporary disability, up to one year, instead of the ordinary temporary disability check.

The practical differences are substantial:

• 100% of regular salary rather than roughly two-thirds
• No temporary disability maximum. The 2026 cap of $1,764.11 per week doesn’t truncate a higher salary.
• Health benefits generally continue during the leave
• Pension contributions generally continue, which protects retirement service credit — a significant long-term item that’s easy to overlook while focused on the immediate injury
• The tax treatment differs from ordinary wages, and many employees find their take-home pay lands closer to normal than the gross figures suggest. How that applies to you is a question for a tax professional, not for a workers’ compensation article.

The one-year term runs as a period of disability, and how it interacts with intermittent time off, modified duty, and multiple injuries can get technical quickly.

The Presumptions — a Second Major Advantage

Public safety employees also benefit from something ordinary workers don’t have: statutory presumptions that certain conditions are work-related.

In an ordinary comp claim, the injured worker carries the burden of showing the injury arose out of and in the course of employment. That’s manageable for a fall from a ladder and very difficult for a disease that developed over years.

For covered public safety employees, California law presumes that certain conditions — depending on classification, these can include heart trouble, cancer, certain infectious and respiratory diseases, hernia, and others — arose out of employment. The burden shifts to the employer to rebut the presumption, which is a fundamentally different posture.

For a firefighter in the Sierra foothills with a cancer diagnosis after years of wildland smoke exposure, that presumption may be the entire case. The specific presumptions, the classifications they attach to, and the periods during which they extend after separation from service are all statute-specific — this is an area where the details genuinely decide outcomes, and where getting advice early is worth far more than getting it later.

What Happens After the Year Runs

Section 4850 provides up to one year. If you’re still temporarily disabled when it ends, you generally transition to ordinary temporary disability payments, subject to the caps that apply to your claim — meaning the drop to two-thirds arrives at the twelve-month mark.

That transition point is usually when several other questions arrive at once:

• Industrial disability retirement. For many public safety employees this is the most consequential decision in the entire case, with tax and pension consequences that dwarf the workers’ compensation award itself.
• Permanent disability rating, once you’re declared permanent and stationary.
• Whether you can return to full duty, and what happens if you can’t.
• Social Security Disability, where the condition is long-term — and how it coordinates with a pension.

These decisions interact. Getting the workers’ compensation piece right while ignoring the retirement piece can cost far more than it saves, which is why public safety cases are worth handling as one connected problem rather than a series of separate forms.

Frequently Asked Questions

What is Labor Code 4850?

It’s the statute giving specified California public safety employees a leave of absence at full salary — instead of ordinary temporary disability — for up to one year following a job-related injury or illness.

How is it different from regular temporary disability?

Regular temporary disability pays about two-thirds of wages up to a statutory maximum ($1,764.11 per week in 2026). Section 4850 pays full salary with no such cap, for up to a year.

Do health benefits and pension contributions continue?

Generally yes, which protects both your coverage and your retirement service credit during the leave.

Do I have to prove my heart condition or cancer came from the job?

Where a statutory presumption applies to your classification and condition, the condition is presumed industrial and the employer bears the burden of rebutting it. Which presumptions apply depends on your specific classification.

What happens when the year is up?

If you’re still temporarily disabled you generally move to ordinary temporary disability. That’s also typically when industrial disability retirement and permanent disability questions come to the front.

Get Advice Before the Year Runs Out

Public safety claims carry better benefits than ordinary comp claims and considerably more complexity — presumptions, salary continuation, pension interaction, and industrial disability retirement all moving at once.
