Did the insurance company deny your Pasadena workers' comp claim? A denial is not the end of your case. It is the start of the fight for what you are owed. You have real ways to push back, and the deadlines are short.
If your claim or your treatment was turned down, you can appeal. A successful appeal can restore what the denial took. That means your paid medical treatment, your wage checks (two-thirds of your pay, up to 104 weeks), and your permanent disability award. You pay nothing up front to challenge a denial. The same rights protect you whether you nurse at Huntington Hospital, cook in Old Town, or work a Caltech lab.
Here is what to do today:
Yes. Almost every denial can be appealed. A denied treatment goes to Independent Medical Review. A denied claim or a bad ruling goes to a Petition for Reconsideration at the WCAB.
Insurers deny claims for all kinds of reasons. They say the injury did not happen at work. They blame an old condition. They cut off care a doctor ordered. None of that is the last word. California gives every injured worker a way to challenge a denial. The right path depends on what was denied, and we lay out both roads below.
Pasadena workers bring us the same denials again and again. A veteran nurse at Huntington Hospital or Kaiser watches apportionment slash her lumbar award. A Caltech or JPL technician with a thin paper trail gets a quick denial. A hotel housekeeper or line cook sees a needed surgery refused at review. Every one of these can be appealed.
It depends on what was denied. A denied treatment is fought through Independent Medical Review. A denied claim or a bad judge's decision is fought through a Petition for Reconsideration at the WCAB.
There are two very different kinds of denial, and they take two different roads. Getting on the wrong road wastes days you cannot spare. Here is how to tell which one is yours.
When your doctor requests surgery, therapy, or an MRI, the insurer sends it to utilization review. A reviewer you never meet can deny or change the request. You cannot take a treatment denial straight to a judge. You appeal it through Independent Medical Review, and you have 30 days from the denial to file. An outside doctor then weighs the decision against the state's treatment guidelines.
IMR is built to be the final word on medical necessity. Under §4610.6, you can challenge an IMR result only on narrow grounds, like fraud, a serious conflict of interest, or clear bias. That is why the first appeal has to be strong. We build it with your treating doctor's report, your imaging, and proof that simpler care already failed.
A denied claim is different from a denied treatment. So is a ruling you believe a judge got wrong. After a workers' compensation judge issues a Findings and Award, you challenge it with a Petition for Reconsideration under §5903. A panel of commissioners who run the WCAB then reviews what the judge did.
Labor Code §5903: "At any time within 25 days after the service of any final order, decision, or award... any person aggrieved thereby may petition for reconsideration upon one or more of the following grounds and no other."
The grounds matter. You can argue the evidence does not support the findings. You can argue the judge acted beyond the law, or that important new evidence has surfaced. Simply disliking the result is not enough. We frame the petition around the exact legal error, and we cite the pages of the record that prove it.
You file your petition electronically through the WCAB's EAMS system. The judge reports on it, a panel of commissioners decides, and a still-wrong result can go up to the Court of Appeal.
A Petition for Reconsideration is filed through the state's electronic system, called EAMS, at the district office where your judge sits. The judge who heard your case writes a report answering your arguments first. Then a three-member panel of WCAB commissioners reviews the whole record. They can uphold the decision, change it, or send it back for more evidence.
If the commissioners still rule against you, the fight is not always over. You can ask the Court of Appeal to review the decision, and you have 45 days to file. And if your case already closed but your injury later worsens, you have another option. You may be able to reopen it within five years of the original injury. Each step has a hard deadline, so do not wait to get advice.
Substantial medical evidence. Appeals are won on the record and the doctors' reports, not on how unfair the denial felt. A report's reasoning matters more than its conclusion.
Most appeals turn on one phrase: substantial medical evidence. A doctor's opinion only carries weight when it explains the how and the why behind it. A report that gives a conclusion with no reasons can be set aside, and a sharp appeal attacks exactly that gap. Weak reports decide cases that should have gone the other way.
Three errors drive most of the Pasadena appeals we take. The first is bad apportionment. On a long-tenure nurse at Huntington Hospital or Kaiser, the insurer pins the disability on old wear instead of the job. The rule from Escobedo v. Marshalls, a WCAB en banc decision, allows that split only with real medical reasons. A guess does not qualify.
The second error is a rating that ignores how hard the job is. On a hotel or light-industrial file, the wrong occupational adjustment can cut an award by thousands of dollars. The third is a botched panel QME process, like a missed strike or a mismatched specialty. On a thin Caltech or JPL file, we also fight fast denials that ignored the 90-day rule. We rebuild the record and force each report to meet the legal standard.
Not long. Most appeal clocks run 20 to 45 days, and a missed deadline can end your case for good. The table below shows the exact window for each kind of denial.
Appeal deadlines in workers' comp are short and unforgiving. Miss one and you can lose the right to fight, no matter how strong your case is. The date that starts the clock sits on the denial or the decision itself. Here is every appeal route and its deadline in one place.
| 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 |

Tap to call →It is one of the busiest appeal venues in the state. Eman Yazdchi files reconsideration petitions there and at the Pomona office, and knows the local judges and the panel process.
Most Pasadena cases are heard at the Los Angeles district office of the WCAB, at 320 W. 4th Street downtown. Some San Gabriel Valley files are venued at the Pomona district office instead. Your Petition for Reconsideration is filed through EAMS at the office where your judge issued the decision. Yazdchi Law appears regularly at both the Los Angeles and Pomona offices on appeal matters.
The work that defines Pasadena drives the appeals we handle:
Did a Huntington Hospital or Kaiser unit fail to keep a trained lift team or the right equipment? That gap can help show your injury came from the job. It can also support a serious-and-willful penalty claim, though that carries a high bar of proof. These claims get denied often, and a denial can be appealed. We know how to build the record the law requires. Related: California healthcare-worker injury claims.
Nothing up front. You pay no fee unless your appeal wins. A WCAB judge sets the fee in California, usually 12 to 15 percent of your recovery.
There is no hourly bill and no charge to begin your appeal. A WCAB judge sets the attorney fee, normally 12 to 15 percent of what your appeal recovers. You owe it only if we win. Lose, and you pay no fee at all. A housekeeper at the Langham gets the same representation as a Caltech researcher, whatever the paycheck.
