A denial is not the end. It is the start of the fight for your benefits. Maybe a Van Nuys insurer denied your claim. Maybe its review company refused the surgery your doctor ordered. Maybe a judge ruled against you. You can still challenge it, and getting started costs you nothing up front.
Here is the short version, in plain terms. A denied treatment can go to an independent doctor for review within 30 days. A denied claim or a bad ruling can go to a Petition for Reconsideration, then up to the Court of Appeal. A closed case can sometimes be reopened if your injury gets worse. These rights protect every Valley worker. That holds whether you load ramps at Van Nuys Airport, run the brewery line, or lift patients at a Valley hospital.
Here is what to do today:
Yes. A denial or a cut-off is not final. You can appeal a denied treatment within 30 days, and a judge's decision within about 25 days.
Most workers who call us just got bad news. The insurer denied the claim, or its reviewer refused the surgery, or a judge's decision came back wrong. The first thing to know is simple. A no is not always final. California gives you clear ways to challenge each kind of denial, and strict clocks to use them.
It also helps to know the rules already on your side. While the insurer investigates a new claim, the law still owes you up to $10,000 in early medical care. If they sit on the decision past 90 days, your injury can be presumed covered. A denial that ignores those rules is the kind we challenge hard.
Which appeal you file depends on what got denied. A denied medical treatment follows one road. A denied claim or a bad court decision follows a different one. Pick the wrong road, or miss the date, and even a strong case can sink. Sorting that out is the part we handle for Valley workers every week.
Treatment denials go to Utilization Review, then Independent Medical Review. Denied claims and bad rulings go to a Petition for Reconsideration at the Appeals Board.
When your doctor asks for surgery, therapy, or medication, the insurer routes the request to utilization review. That is a paper review, often by a reviewer who never examines you. If they deny or cut the care, you do not argue it in front of the judge. You appeal to Independent Medical Review within 30 days of the denial. An outside doctor then weighs the request against the state's treatment guidelines.
Here is the hard part that surprises most workers. An IMR result is close to final. Under §4610.6, you can challenge it only on narrow grounds. Those include fraud, a clear conflict of interest, bias, or a plain mistake of fact. You cannot appeal just because you disagree. So the first IMR submission has to be built right, with the records that match the guideline the reviewer uses.
A denied claim, or a Findings and Award you believe is wrong, takes the other road. You file a Petition for Reconsideration under §5903. It asks the Workers' Compensation Appeals Board to take a second look at the judge's decision. The window is tight. You get 25 days when the decision was mailed, and only 20 days when it was served electronically.
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 party any relief, any aggrieved person may petition for reconsideration..."
The petition must name the legal reason the decision was wrong. Being unhappy is not a ground. Common grounds are that the evidence did not support the finding, that the judge applied the law incorrectly, or that new evidence has surfaced. If the Appeals Board still rules against you, the next step is the Court of Appeal by writ of review, filed within 45 days.
Sometimes a case settles or closes, and later the injury turns worse. You may be able to reopen it for new or further disability, but only within five years of the date of injury. Once that window shuts, it is gone. If an old Van Nuys injury is flaring again, do not guess at your timing. Find out where you stand.
Not long. A denied treatment gives you 30 days. A judge's decision gives you 25 days if mailed, 20 if electronic. Miss it and your case can end.
Appeal deadlines in workers' comp are short and unforgiving. Each kind of denial runs its own clock, and the clock starts on the date of the denial, not the day you read it. Here is every appeal route, the deadline, and the law behind 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 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 |

You file the petition, the insurer answers, and a judge or the Appeals Board reviews the record. You may get a new hearing or a corrected award.
Most workers picture a dramatic courtroom. The truth is quieter, and that is good news, because appeals are won on the record. Here is how a reconsideration usually moves on a Van Nuys file.
First, we file your petition at the Van Nuys district office, where your case lives. It lays out each error and points to the exact evidence in your file. The judge who made the decision then writes a report on your petition. From there, the seven-member Appeals Board reviews the record. It can affirm the ruling, change it, or send the case back for a new hearing.
A treatment appeal moves faster but stricter. The IMR doctor reviews your records on paper, and there is no hearing. So what goes into the file up front decides the result. We make sure the request, the imaging, and your treating doctor's report all line up before the review, not after.
Evidence that answers the exact reason for the denial. A medical report that shows the how and why, records that meet the guidelines, and proof tied to your job.
Appeals are won on proof, not on how loudly you argue. The insurer denied your claim or your care for a stated reason. The winning appeal meets that reason head-on with evidence. A few kinds of proof do most of the work.
A strong medical-legal report is usually the heart of it. In a disputed case, a Qualified Medical Evaluator chosen from a state panel examines you and writes the opinion the judge leans on. When the fight is over apportionment, that doctor must show the how and why of any split between your job and other causes. A report that skips the reasoning can be tossed out on appeal.
For a denied treatment, the proof is your records measured against the guidelines: failed conservative care, imaging that backs the request, and your treating doctor's clear opinion. For a denied claim, it is proof the injury came from work, like the auto-shop task that hurt you or the years on the brewery line that wore you down. And if your employer punished you for filing, that illegal retaliation becomes its own claim for lost pay and a penalty.
Everything above rests on these California Labor Code sections. Each link opens the official statute text.

Injured at work in Van Nuys? Call (661) 273-1780
Tap to call →It hears Valley cases from the airport, the brewery, auto row, garment shops, and Valley hospitals. Eman Yazdchi files appeals there often and knows its judges.
San Fernando Valley appeals are handled at the Van Nuys district office of the Workers' Compensation Appeals Board, at 15400 Sherman Way, Suite 500. Your Petition for Reconsideration is filed there, inside your case file, then forwarded up to the Appeals Board commissioners. The district reaches Van Nuys, Sherman Oaks, Encino, Reseda, Northridge, North Hollywood, Panorama City, Pacoima, Sun Valley, and the rest of the east Valley. Yazdchi Law appears there often on reconsideration and IMR disputes. Related: Van Nuys workers' comp claims.
The denials we challenge in Van Nuys track the Valley's real economy:
Two fights come up again and again on Valley files. The first is apportionment, where the insurer blames an airport ramp worker's bad back on age instead of the job. The how-and-why rule, confirmed by the Appeals Board in Escobedo v. Marshalls, lets us attack a guess-based split. The second is the date of injury on a build-up claim, common with brewery and garment workers. That date can decide whether the claim is even on time. We also challenge rejected serious-and-willful claims after a construction fall-protection failure. The disputed medical opinion usually turns on the panel QME. The state QME directory is here.
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 pay us nothing to start, and nothing by the hour. In California workers' comp, the WCAB judge sets the attorney fee, usually 12 to 15 percent of the back benefits or settlement we win, and only if we win. Lose, and you owe no fee. That keeps top-level appeal help within reach of an airport mechanic or a sewing-machine operator, the same as anyone else.
