Did the insurance company deny your workers' comp claim, or shut off the care your doctor ordered? Here in Mount Washington, that letter hits hard. You are worried about rent, your job, and your health all at once. Take a breath. A denial is not the end. It is the beginning of the fight for what you are owed.
California law gives you a real right to appeal, whether a review nurse blocked your surgery or a judge ruled against you. The catch is timing. Some appeal clocks run as short as 20 days. Miss one and the right can vanish for good. The smartest move is to call a lawyer the day your denial lands.
Here is what to do today:
Yes. Almost every denial can be appealed. A blocked treatment goes to Independent Medical Review within 30 days; a denied claim or ruling goes to a Petition for Reconsideration.
Most workers who open a denial letter assume the door is shut. It rarely is. Insurers deny claims they later pay, and review nurses block care that an outside doctor later approves. Maybe you ring up sales at a Figueroa Street shop. Maybe you lift patients at Keck Hospital of USC, or frame houses above the Arroyo Seco. The same appeal rights protect every one of you. You generally have one year from the injury just to open the claim, then short clocks to appeal any denial. The trick is matching your denial to the right path and filing in time.
It depends on what was denied. A blocked treatment runs through Utilization Review, then Independent Medical Review. A denied claim or ruling goes to a Petition for Reconsideration.
First, separate a delay from a denial. Even while the insurer investigates, it has only 90 days to accept or deny your claim. In the meantime, it owes up to $10,000 in care. Miss that 90-day window, and the law presumes your injury is covered. A flat denial is a different animal, and how you fight it depends on what got denied.
When your doctor requests surgery, therapy, or an MRI, the insurer routes it to its own utilization review. If that reviewer says no, you do not argue back with the insurer. You appeal to Independent Medical Review within 30 days of the denial. An outside doctor then weighs the request against California's treatment guidelines and either overturns or upholds the block.
Here is the catch. An IMR result is close to final. Under §4610.6, you can challenge it only on narrow grounds: fraud, a clear conflict of interest, or a record mistake. You cannot appeal just because you disagree. That is why the first IMR packet must be built right, and why workers call us before they file it.
A denied claim, or a judge's decision that got the facts or the law wrong, takes another road. You file a Petition for Reconsideration under §5903 with the Workers' Compensation Appeals Board. It asks the board to re-examine the trial judge's Findings and Award. This is not the place to re-argue your feelings. The petition must rest on one of five legal grounds and cite the record.
Labor Code §5903: "At any time within 20 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 compensation, or arising out of or incidental thereto, any person aggrieved thereby may petition for reconsideration upon one or more of the following grounds and no other:"
The statute counts 20 days. When the decision arrives by mail, you add five days, so your real deadline is 25 days. If the board turns reconsideration down, one road is left. You can take a writ of review to the California Court of Appeal, which for Mount Washington means the Second Appellate District. That court rarely agrees to hear these cases, and it only asks whether substantial evidence backed the ruling. Did your case already close, but your injury later got worse? You may be able to reopen it for new or worse disability within five years of the injury.
Not long. A denied treatment gives you 30 days for Independent Medical Review. A judge's decision gives you 25 days if it was mailed, 20 if served electronically.
Every route has its own clock, and the board rarely forgives a late filing. The table below shows the deadline for each kind of denial a Mount Washington worker tends to face. Count from the date on the denial or the proof of service, not the day you happen to read it.
| 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 |

For a treatment fight, an outside doctor reviews your records on paper. For a claim or ruling, you file a written petition and the board reviews the trial record.
A treatment appeal has no hearing. Independent Medical Review happens on paper. An anonymous doctor reads your records against the state guidelines and rules within set time limits. Because nobody testifies, your records and the appeal letter carry the entire case. A strong packet matters more than anything you could say out loud.
A Petition for Reconsideration has more moving parts. We file it with the board's Reconsideration Unit through the state's electronic system. The insurer gets about 20 days to file an answer. Your trial judge writes a report on the petition, and then the board generally acts within roughly 60 days. Under §4610.6, a treatment question already settled through IMR cannot be reopened here.
Records, not emotion. A winning appeal shows failed conservative care, clear imaging, a detailed treating-doctor opinion, and pinpoint cites to where the decision went wrong.
Appeals are won on paper. For a denied surgery, the review doctor wants three things. Proof that you already tried the safer options. Scans that match the diagnosis. And your treating physician's reason that the next step is medically necessary. A request that skips those pieces gets blocked, even when the worker plainly needs the care.
A Petition for Reconsideration demands pinpoint accuracy. We comb the hearing transcript and the medical reports, then show exactly where the judge misread the evidence or misapplied the law. A frequent winner is an apportionment ruling built on a panel doctor's vague say-so. That doctor blamed an old injury but never explained the how and why. Vague opinions like that fail the substantial-evidence test the board set in Escobedo v. Marshalls. Fixing one can swing an award by tens of thousands of dollars.
Everything above rests on these California Labor Code sections. Each link opens the official statute text.

Tap to call →Mount Washington appeals are heard at the downtown Los Angeles WCAB. Eman Yazdchi files reconsideration petitions there often and knows its judges, e-filing rules, and the writ court.
Your reconsideration petition is e-filed through the state's electronic system to the board's Reconsideration Unit. The venue is the Los Angeles district office at 320 West Fourth Street, Suite 600, downtown. From the hillside streets above the Arroyo Seco, the board sits a short drive away. You can reach it on the 110, the 5, the 101, or Metro Rail. If reconsideration fails, the writ goes to the California Court of Appeal, Second Appellate District, which covers all of Los Angeles County.
The denials we see track the neighborhood's working life:
A petition the Los Angeles board takes seriously does four things. It states the legal ground for the appeal. It lays out the facts with citations to the trial record. It argues the controlling California case law. And it proposes the corrected order you want. We build all four, and we know how the local judges read them.
Nothing up front, and nothing unless we win. The WCAB judge sets the fee, usually 12 to 15 percent of the added benefits the appeal recovers for you.
You pay no hourly bill and nothing to begin. In California workers' comp, the judge sets the attorney fee. It is generally 12 to 15 percent of what the appeal actually wins, and only if it wins. If the appeal recovers nothing, you owe no fee. A line cook on Figueroa Street gets the same fight as anyone else.
