Did the insurance company deny your claim, or cut off care your doctor said you still need? A denial is not the end. It is the beginning of the fight. You have the right to appeal, and starting that fight costs you nothing up front.
Maybe you stock shelves in a Pico-Union warehouse, lift patients at Good Samaritan, cook in a Koreatown kitchen, or sew in a garment shop off Olympic. A denial letter is one company's opinion. It is not a final ruling. California gives you clear appeal routes, and each one has its own deadline.
The deadline is what matters most today. Miss it and the decision usually becomes final, even when it was wrong. That is the one mistake you cannot undo. So your first job is simple. Find out which clock is running and how many days are left.
An appeal costs you nothing out of pocket. The fee is a share of what we win, set by the judge, and only if we recover. Your immigration status does not change any of this.
Here is what to do today:
Very likely yes. A denied claim, cut-off treatment, or a judge's decision that shorted you can each be appealed if you act before the deadline.
Most workers think a denial is the last word. It is not. The insurer that denied you is just one side of a dispute. You get to take that dispute to a neutral decision-maker. What changes is the route you use. A denied treatment, a denied claim, and a bad ruling from a judge each travel a different path. Pick the wrong one, or miss the date, and you can lose a strong case on a technicality. So the first step is naming your route.
It depends on what was denied. Cut-off treatment goes to medical review. A denied claim or wrong ruling goes to a Petition for Reconsideration.
When Utilization Review cuts off therapy, a surgery, or medicine your doctor ordered, you do not start with a judge. You appeal to Independent Medical Review within 30 days of the denial. An outside doctor then checks the decision against the state's treatment guidelines. This is the path for the Good Samaritan nurse whose physical therapy stopped halfway through her recovery.
That medical review is hard to undo. If it still upholds the denial, you can challenge the result only on narrow grounds, like fraud, bias, or a clear conflict of interest. So the medical-review round is the one that counts. We build the strongest record we can before that 30-day window closes.
A denied claim is different. The insurer might reject your whole case. Or a workers' comp judge might issue a decision that gets the facts or the law wrong. Either way, you fight back with a Petition for Reconsideration under §5903. This is the spine of a Los Angeles appeal, and the law is strict about it.
Labor Code §5903: "At any time within 25 days after the service of any final order, decision, or award made and filed by the appeals board or a workers' compensation judge granting or denying any claim for compensation, any party aggrieved thereby may petition for reconsideration upon one or more of the following grounds and no other."
Read that deadline again. Twenty-five days. You also have to name one of five legal grounds and tie it to the trial record. A petition that just says the judge was unfair, with no grounds and no record cites, gets denied. If reconsideration fails, the last step is a Writ of Review to the Court of Appeal. And a case that already closed can sometimes be reopened for new or worse disability.
Not long. Treatment denials give you 30 days. A mailed judge's decision gives you 25 days. Miss the date and the ruling usually becomes final.
Every appeal route runs on a short clock. The clock starts when the decision is served, not when you understand it. Here is the full set, side by side.
| 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 |
In Los Angeles, a reconsideration petition is e-filed through the state's EAMS system to the WCAB Reconsideration Unit. Not sure which clock is yours? One free call sorts it out fast: (661) 273-1780.
You file a verified petition. The insurer answers within 20 days. The appeals board then has 60 days to act on it.
Reconsideration is paperwork-driven. It is not a brand-new trial. You file a verified petition that lays out your grounds and cites the record from your hearing. The insurer then has 20 days to file an answer. After that, the WCAB Reconsideration Unit has 60 days to act on your petition. It can grant it, deny it, or send the case back to your trial judge for another look.
If the board denies reconsideration, your file can move up. You ask the California Court of Appeal, Second Appellate District, to take the case by writ. That court covers Los Angeles County. Writ review is discretionary and granted sparingly. Still, it is the only door to a higher court after a final board order. We map this whole sequence out at the first meeting, so no deadline catches you off guard.
Substantial medical evidence and a clean record. Appeals are won on the doctor's reasoning and the trial transcript, not on how unfair the result felt.
Appeals are not won by anger. They are won by the record. The Second District reviews a board decision under the substantial-evidence standard. That is the same test that governs every California administrative appeal. So the question is whether real evidence backs the result. Three things tend to carry the most weight.
This is detail work. It is where a Certified Specialist earns the fee. We find the weak point in the denial and put it in front of the board in writing.
Every step above rests on these California Labor Code sections. Each link opens the official statute text.

Tap to call →The downtown LA board hears a heavy volume of South LA appeals. Eman Yazdchi files reconsideration there often and knows its judges, clerks, and timelines.
Olympic Park cases are heard at the Los Angeles district office of the Workers' Compensation Appeals Board. The address is 320 West Fourth Street, Suite 600, in downtown Los Angeles. It sits a short ride from the Olympic and Western corridor by Metro Rail and the 110, 101, and 5 freeways. The office covers Los Angeles County. Petitions are e-filed through EAMS to the Reconsideration Unit. Related: Los Angeles workers' comp claims.
The neighborhood's mix of hospitals, warehouses, and small businesses drives the denials we appeal:
After you e-file through EAMS, the insurer has 20 days to answer your petition. The Reconsideration Unit then has 60 days to act. It can grant review, deny it, or return the case to your trial judge. The judge who heard your case writes a report recommending how the board should rule. That is why a clean trial record matters so much. Related: California healthcare-worker injury claims.
If the board denies reconsideration, the next step is a writ to the California Court of Appeal, Second Appellate District, which hears Los Angeles County cases. You have 45 days. The court applies the substantial-evidence standard and grants writs sparingly. So the record you built below is what decides it. We brief these petitions tightly, and only when the law gives you a real shot.
Nothing up front, and nothing unless we win. California workers' comp fees are judge-set, usually 12 to 15 percent of what we recover for you.
You do not pay by the hour, and you pay nothing to start. Attorney fees in California workers' comp are set by the WCAB judge. They run about 12 to 15 percent of your award or settlement, and only if we recover for you. If there is no recovery, you owe no fee. A warehouse loader and a hospital nurse get the same quality of representation.
