Did an insurance company deny your Lomita workers' comp claim, or cut off the treatment your doctor ordered? A denial is not the end. It is the start of the fight.
The law gives every injured California worker a way to challenge a denial, no matter your immigration status. A denied surgery or therapy can be appealed. A bad decision from a workers' comp judge can be appealed too. The deadlines are short, but you still have rights, and using them costs you nothing up front.
If you just got a denial, here is what to do today:
Most likely yes. A denied treatment goes to Independent Medical Review within 30 days. A judge's bad ruling goes to Reconsideration within about three weeks.
Almost every denial can be challenged. The insurance company is hoping you read the letter, feel beaten, and walk away. Many workers who do that lose benefits they were owed. You do not have to. Whether the insurer denied your whole claim, stopped your wage checks, or refused a surgery, there is a path to push back. The trick is knowing which path is yours and moving before the deadline.
Lomita workers come to us after every kind of denial. A line cook on Pacific Coast Highway whose shoulder care was stopped. An auto-repair tech off Narbonne Avenue whose back claim was rejected. A nurse who commutes to Providence Little Company of Mary in Torrance and had her surgery denied. The same appeal rights cover all of them.
It depends on what got denied. A denied treatment follows the medical-review path. A denied claim or a judge's ruling follows the court-style appeal path.
There are two very different kinds of denial, and they travel two different roads. Mixing them up can cost you the case. Here is the plain version of each.
When your doctor asks for surgery, therapy, or an MRI, the insurer sends the request to a reviewer first. That step is called Utilization Review. If the reviewer says no, you do not argue with the insurer. You appeal to an outside doctor through Independent Medical Review, and you have just 30 days from the denial to file. That physician checks your records against the state's treatment guidelines, then overturns or upholds the denial.
IMR is powerful, but it is also nearly the last word. Under §4610.6, an IMR decision is presumed correct. A judge can set it aside only on narrow grounds, like fraud, bias, or a clear conflict of interest. That is why the appeal has to be done right the first time. We build the medical record before the 30-day window closes, not after.
The other road is for legal denials, not medical ones. Maybe the insurer denied your whole claim. Maybe a workers' comp judge issued a decision that got your disability wrong, or threw out your case after trial. You fight that with a Petition for Reconsideration under §5903. It asks the seven-member Appeals Board to review what the judge did. The deadline is tight: 25 days if the decision was mailed, 20 days if it was served electronically.
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 ..., any person aggrieved thereby may petition for reconsideration upon one or more of the following grounds and no other."
The petition cannot simply say the judge was unfair. It has to name a legal ground. Examples include the evidence not supporting the decision, or new evidence you could not have found before trial. If the Appeals Board turns you down, you can ask the Court of Appeal to review the case by writ. You get 45 days for that. These deadlines are hard stops, and filing one day late usually ends the appeal for good.
One more thing. If your employer fired you or cut your hours for filing or appealing, that is illegal retaliation. You can win your job back, your lost pay, and a penalty added to your award.
A closed case is not always final either. If your injury gets worse, or new disability appears, you may be able to reopen the case for more benefits. The window is five years from the date of your injury, not from when the case closed. A Lomita warehouse worker whose back settles, then needs a fusion two years later, may fit this rule. We review old files to see whether reopening is worth it.
Not long. A denied treatment gives you 30 days. A judge's ruling gives you 20 to 25 days. Miss the date and the appeal is usually lost for good.
Deadlines are the heart of every appeal, and they are short on purpose. The insurer is counting on them running out. This is the most important thing for a Lomita worker to track. The date your appeal is due depends on what was denied and how you were served. Here is the full map.
| 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 and 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 |

It runs mostly on paper, not in a courtroom. An outside doctor reviews a denied treatment. A judge and the Appeals Board review a denied claim.
Most workers picture a courtroom showdown. Real appeals are quieter and run on documents. For a denied treatment, your IMR appeal is decided by an independent doctor who never meets you. The records do the talking, so they have to be complete and clear.
For a denied claim, the petition goes to the trial judge first. The judge can change the ruling, or send it up to the Appeals Board with a report. The board can affirm it, reverse it, or return the case for more evidence. Most of this happens without you taking the stand again. Your job is to get us the paperwork fast so we can hit the deadline.
The right records. A treatment appeal needs proof the care is necessary. A claim appeal needs proof the ruling did not match the evidence.
Appeals are won on the record, not on how angry you are. Each road needs its own kind of proof.
To overturn a denied treatment at IMR, you show the care meets the state's medical guidelines. That usually means imaging that confirms the injury, notes showing simpler care already failed, and your treating doctor's clear reasons for the next step. A Lomita nurse whose Torrance-hospital back surgery was denied wins by showing the MRI and the failed therapy, not by arguing.
To win a Petition for Reconsideration, you show the judge's decision does not fit the evidence. Often that means challenging a weak medical-legal report. A report that blames your disability on old age or prior wear, without explaining the how and why, is not substantial evidence. The Appeals Board made this clear in Escobedo v. Marshalls, a 2005 en banc decision. Blaming a disability on old wear takes real medical proof, not a guess. The doctors who examine you come from a state panel, and which one decides your case can change everything.
Every step above comes from these California Labor Code sections. Each link opens the official text.

Tap to call →Lomita cases are heard at the Los Angeles district WCAB, but a Petition for Reconsideration is decided by the seven-member Appeals Board. Eman Yazdchi appears there often.
Lomita sits in the South Bay. Your workers' comp case is heard at the Los Angeles district office of the Appeals Board, at 320 West 4th Street. The judge whose decision you are appealing sits there. A Petition for Reconsideration is filed at that LA office, then decided by the seven-member Appeals Board. The record built at the LA hearings is what every higher review reads. Yazdchi Law appears at the Los Angeles WCAB often on denied and appealed claims.
Lomita is a small, close-knit city built on small businesses, from the shops near the Lomita Railroad Museum to the auto rows along Narbonne Avenue. The work that fills our Lomita appeal caseload reflects that:
An appeal lives or dies on dates, and Los Angeles handles a huge volume of cases. Decisions get mailed, sometimes served by email, and the clock starts the moment they go out. We track the 25-day mailed and 20-day electronic deadlines on every decision a client brings us. Missing the date by a single day can sink an otherwise strong appeal. That is the one mistake we never let a Lomita client make.
Nothing up front, and nothing unless we win. Workers' comp fees in California are set by the judge, usually 12 to 15 percent of what we recover for you.
You pay us nothing to start an appeal, and nothing by the hour. In California workers' comp, the judge sets the attorney fee, usually 12 to 15 percent of what we win for you. If we recover nothing, you owe no fee. So a Lomita line cook gets the same fight as someone with deep pockets. The 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, because every case is different.
