Did the insurance company deny your Calabasas workers' comp claim, or cut off the treatment your doctor ordered? Take a breath. A denial is not the end of your case. It is the beginning of the fight for what you are owed.
Here is the part insurers hope you never learn. Almost every denial can be appealed. A denied surgery or therapy can go to an independent doctor. A bad ruling from a judge can go to a higher panel. You pay nothing up front to push back, and the clock to act is short.
Two deadlines matter most. If your treatment was denied, you have 30 days to appeal it. If a judge ruled against you, you have about 25 days to ask for reconsideration. Miss either window and the denial can stick. So the first move is simple: find the date on your denial letter.
Here is what to do today:
- Find the denial letter or the judge's decision. Look for the date it was mailed or served. Your deadline counts from that date.
- Mark the deadline now. Some appeal windows are as short as 20 days. Do not wait for it to feel urgent.
- Call before the clock runs out. A free review tells you which appeal fits and what proof you need. Reach us at (661) 273-1780.
Was your Calabasas claim denied? You can fight it.
Most likely yes. A denied treatment, a rejected claim, or a bad ruling can each be appealed, if you act inside the deadline.
Most injured workers think a denial letter is the final word. It is not. California gives you a clear path to challenge nearly every kind of denial. The insurer is betting you will give up or miss the deadline. Many people do. The workers who appeal on time, with the right proof, often win the care or money the insurer first refused.
It does not matter where in Calabasas you work. A server at The Commons has the same right to appeal as a medical assistant at a Cedars-Sinai office. So does an aide in the Las Virgenes schools or a groundskeeper at the country club. Your immigration status does not change that right. We handle the paperwork, the deadlines, and the hearings for you.
UR vs IMR vs a WCAB appeal: which path is yours?
It depends on what was denied. A denied treatment goes to Independent Medical Review. A denied claim or ruling goes to the Appeals Board.
There is no single appeal. The right path depends on what the insurer or the judge said no to. Picking the wrong route wastes time you may not have. Here are the three paths that cover almost every case.
Denied treatment: Utilization Review, then IMR
When your doctor asks to approve a surgery or therapy, the insurer sends it to Utilization Review. A reviewer who never examines you can approve, change, or deny it. If they deny or cut it, you do not argue with that reviewer. You appeal to Independent Medical Review, within 30 days. An outside doctor then checks your records against the state treatment guidelines.
IMR is where many workers get stuck, because the result is hard to undo. By law, an IMR decision is treated as correct and is final on the medical question. You can challenge it only on narrow grounds, and the bar is high.
Labor Code §4610.6: "The determination of the administrative director shall be presumed to be correct and shall be set aside only upon proof by clear and convincing evidence of one or more of the following grounds for appeal."
Those narrow grounds under §4610.6 include fraud, a reviewer with a conflict of interest, bias, or a plain mistake of fact. This is exactly why the first IMR appeal has to be done right. A strong record up front beats a long-shot challenge later.
Denied claim or a bad ruling: Petition for Reconsideration
A different route applies when the insurer rejects your whole claim. The same is true when a workers' comp judge rules against you after a trial. That written ruling is called a Findings and Award. To challenge it, you file a Petition for Reconsideration under §5903. It goes to the Workers' Compensation Appeals Board, a panel of commissioners who review the judge's work.
You have a short window. The deadline is 25 days if the decision was mailed to you, or 20 days if it was served electronically. Your petition has to name the legal error, such as a finding the evidence does not support. We draft it to hit those grounds squarely.
Closed case getting worse? You may reopen it.
What if you settled, or your case closed, and now the same injury is worse? You may be able to reopen the case for new or worse disability. The window is five years from the date of injury. This route is easy to miss, so it is worth a quick call to check your dates.
What does the appeal process actually look like?
You file on time, the judge reviews it, then the Appeals Board decides. If they refuse, the next stop is the Court of Appeal.
The process sounds formal, but the steps are clear. Here is the path a Reconsideration takes from the Van Nuys office.
- File on time. The petition goes through the state EAMS system to the Van Nuys district office, addressed to the Appeals Board. The deadline is the hard part.
- The trial judge responds. The same judge who ruled can change course, or write a report defending the decision and send it up.
- The Appeals Board reviews. A panel of commissioners reads the record and your petition. They can grant relief, order a new trial, or deny it.
- The Court of Appeal, if needed. If the Board denies you, you can ask the Court of Appeal to review it, within 45 days. This is called a Writ of Review.
Most appeals are decided on the written record, not a new hearing. That is why what you filed, and what was in the trial record, decides the outcome. The strongest petition points to a specific error and the exact evidence that proves it.
What evidence wins a workers' comp appeal?
A complete medical record, a doctor's report that meets the legal standard, and proof the first decision got a key fact or law wrong.
Appeals are not won by frustration. They are won by the record. The most common reason a denial falls apart is that it rested on a weak medical report. The law calls a solid report substantial medical evidence. That means it explains the how and why, not just a conclusion.
For a denied treatment, a winning IMR appeal usually shows three things. It shows that conservative care already failed, that imaging confirms the injury, and that your doctor ties the request to the state guidelines. For a denied claim, the medical-legal report from the panel evaluation process often decides everything. We make sure that report is built right, because a sloppy one sinks good claims.
We also read the insurer's own paperwork closely. A denial can miss a deadline, ignore a report, or lean on a doctor who never explained the how and why. Each of those is a denial we can attack. If your employer punished you for filing, that is illegal retaliation with its own penalty.
A successful appeal can restore the surgery, the wage checks, or the disability award the insurer denied. Our firm has recovered up to $5,000,000 for a catastrophic spinal-cord injury and $1,500,000 for a cervical-spine injury. Past results do not guarantee future outcomes, and every case is different.

How long do you have to appeal?
Not long. Treatment denials give you 30 days. A judge's ruling gives you about 25 days. Missing the date can end your appeal for good.
Deadlines are the whole game on appeal. The insurer knows that. Tracking your date is the single most important thing you can do right now. This table lays out the main routes, what each one is for, and how long you have.
| What was denied | Your appeal route | Deadline | Law |
|---|---|---|---|
| Treatment denied at Utilization Review | Independent Medical Review | 30 days from the denial | §4610.5 |
| IMR upheld the denial | Appeal only on narrow grounds (fraud, bias, conflict) | 30 days | §4610.6 |
| A judge's decision (Findings & Award) | Petition for Reconsideration | 25 days if mailed, 20 if served electronically | §5903 |
| Reconsideration denied | Writ of Review to the Court of Appeal | 45 days | §5950 |
| New or worse disability after a closed case | Petition to Reopen | Within 5 years of the injury | §5803 |
One more deadline matters before any appeal. After you file a claim, the insurer has 90 days to accept or deny it. While they decide, up to $10,000 in treatment is owed right away. If they blow the 90 days, the law can presume your injury is covered. Not sure where your clock stands? A free call sorts it out: (661) 273-1780.

Tap to call →What is special about appeals at the Van Nuys WCAB?
Calabasas decisions come from the Van Nuys district office. Eman Yazdchi files and argues appeals there often, and knows its judges and routines.
Where is the Van Nuys WCAB, and who does it cover?
Calabasas workers' comp cases are heard at the Van Nuys district office of the Workers' Compensation Appeals Board. The address is 6150 Van Nuys Boulevard, near the corner of Calvert Street. It is a short walk from the Metro Orange Line station. The district covers Calabasas and much of the San Fernando and Conejo Valleys. Its reach runs from Agoura Hills and Woodland Hills across to Van Nuys and Sherman Oaks. Yazdchi Law appears there regularly on denied claims and Reconsideration petitions.
Which Calabasas jobs drive the appeals we see?
The denials that come out of Calabasas track the city's own mix of work:
- Retail and dining: clerks, servers, and kitchen staff at The Commons at Calabasas and the Old Town restaurants. Lift and slip injuries here often get denied as not work-related.
- Corporate offices: staff at Calabasas Hills headquarters such as The Cheesecake Factory and Harbor Freight Tools. Repetitive-strain claims there often draw a Utilization Review denial.
- Healthcare: medical assistants and nurses at Cedars-Sinai outpatient offices, whose treatment requests get cut at Utilization Review.
- Entertainment-adjacent offices: assistants at the talent, management, and post-production firms along Calabasas Road.
- Schools and grounds: custodians, aides, and bus drivers for Las Virgenes Unified, plus kitchen and grounds crews at Calabasas Country Club.
How is an appeal different from the first claim?
The first claim is about proving your injury. An appeal is about proving an error. The Appeals Board does not usually take new testimony. It reads the trial record and asks whether the judge followed the law and the evidence. That changes the strategy. We focus on the exact finding that went wrong and the report that should have controlled. The state QME directory is here.
Denied treatment at a Calabasas clinic?
Did a Cedars-Sinai outpatient office, an urgent care, or a surgeon's request get cut at Utilization Review? Then the IMR clock starts the day of that denial, and 30 days goes fast. Bring us the denial letter and your records. We build the appeal around the treatment guidelines the reviewer is supposed to follow.
What does a Calabasas appeal lawyer cost?
Nothing up front, and nothing unless we win. The judge sets the fee, usually 12 to 15 percent of what we recover for you.
You do not pay by the hour, and you pay nothing to start. In California workers' comp, the WCAB judge sets the attorney fee. It is usually 12 to 15 percent of what your appeal recovers, and only if it recovers something. If there is no recovery, you owe no fee. A retail clerk at The Commons gets the same representation as anyone else.

Frequently Asked Questions
Can I appeal if the insurance company denied my Calabasas workers' comp claim?
Yes. A denial is not final. If the insurer rejected your claim, you can take it to a workers' comp judge at the Van Nuys WCAB. If a judge already ruled against you, you can file a Petition for Reconsideration, usually within 25 days. The key is to act fast and show the denial got a fact or the law wrong. Call (661) 273-1780 for a free review.
My doctor's treatment was denied. How do I appeal it?
A denied treatment goes to Independent Medical Review, not to court. You have 30 days from the denial to ask for it. An independent doctor then reviews your records against the state guidelines. A strong appeal shows failed conservative care, imaging that confirms the injury, and your treating doctor's support. We handle these appeals for workers across Calabasas.
What is the difference between Utilization Review and Independent Medical Review?
Utilization Review is the insurer's first check on a treatment request. Its reviewer can approve, change, or deny what your doctor ordered. If they deny it, Independent Medical Review is your appeal. An outside doctor takes a fresh look at your records. IMR is meant to be final, so the first appeal needs a complete medical record to have the best chance.
How long does a workers' comp claim take to settle in California?
It varies. Many claims settle within one to three years, once your condition is stable and a doctor rates the lasting damage. An appeal can add time, but it can also recover benefits you would otherwise lose. We push to move your case along while protecting its value. A free call gives you a realistic timeline for your situation.
Should I take a lump sum or keep my medical care open?
That depends on your injury and your future needs. A Compromise and Release is a one-time lump sum that usually closes future medical care. A Stipulated Award keeps weekly payments and your medical treatment open. A lump sum can feel good now but fall short later. We walk you through both before you sign anything.
How much of my settlement do I keep after attorney fees?
Most of it. In California workers' comp, the judge sets the attorney fee, usually 12 to 15 percent of your award or settlement. So on a typical case you keep about 85 to 88 cents of every dollar. You pay nothing up front, and the fee comes out only if we recover for you.
Can I be fired for appealing a denied claim in Calabasas?
No. Punishing you for filing or appealing a claim is illegal retaliation under California law. If your employer fires you, cuts your hours, or demotes you, you can win your job back, your lost pay, and a penalty added to your award. Tell us right away if your treatment at work changed after you reported an injury.
Can I appeal a denial if I am undocumented?
Yes. California workers' comp protections apply to every employee, whatever your immigration status. Undocumented retail, restaurant, healthcare, and grounds workers in Calabasas have the same right to appeal a denial as anyone else. Your employer cannot threaten to report you for filing or appealing. That threat is its own violation of California law. Our office is bilingual.
