By Eman Yazdchi, Esq. · Certified Specialist in Workers' Compensation Law, State Bar of California Board of Legal Specialization · Cal Bar #285231
A denial is not the end. It is the beginning of the fight for your benefits.
Getting that letter feels crushing. You were hurt at work, you did everything right, and now the insurance company is saying no. Take a breath. A denial is not a final answer in California workers' comp.
The law gives you real tools to push back. The insurer had a strict deadline to accept or deny your claim. If that window closed without a decision, the law tilts in your favor right now. Even a timely denial is a position you can challenge, not a verdict you have to live with.
Eman Yazdchi is a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California (CA Bar #285231). He handles denied claims at the San Bernardino WCAB for workers from Chino Hills and the surrounding Inland Empire. Call (661) 273-1780 for a free review.
Do this right now:
- Save the denial letter and the envelope. The postmark date protects your appeal window.
- Keep going to your doctor. A denial of the claim does not always stop authorized treatment.
- Call (661) 273-1780 today. Every day you wait is time off your deadline.
Was your Chino Hills claim denied? Here is what to do.
A denial is a legal position, not the final word. You have specific deadlines to challenge it. The day the letter arrives is the day to call a lawyer.
When the denial letter shows up, your first feeling may be anger or hopelessness. That is completely understandable. But in California's workers' comp system, a denial opens a process. The insurance company has to stand behind its reasons. You get to challenge those reasons, bring your own evidence, and have a workers' comp judge decide.
Whether you stock shelves at the Shoppes at Chino Hills or drive routes along the Grand Avenue corridor, the same rules protect you. Chino Valley dairy workers and warehouse employees near the 71 freeway are covered too. A denial does not erase your rights. It starts the next phase of the fight.
Why do insurers deny workers' comp claims?
The four most common reasons: the injury wasn't work-related, a pre-existing condition caused it, you reported too late, or the treatment isn't medically necessary. Every one of these can be challenged.
Insurers deny claims because every denial saves them money. The reasons they use most often are:
- The injury wasn't work-related. They say you got hurt at home, during a personal errand, or outside work hours.
- A pre-existing condition caused it. They point to an old MRI or prior injury and say your pain is not from your current job.
- You reported too late. They argue you missed the 30-day notice window. Exceptions exist, and this defense often fails.
- The treatment is not medically necessary. Their reviewer says the surgery, imaging, or therapy your doctor ordered does not meet the insurer's guidelines.
None of these reasons ends your case. For Chino Hills retail, logistics, and dairy workers who develop injuries over time, the pre-existing-condition denial is the most common one we see at the San Bernardino WCAB. It is also among the most worth fighting. A solid medical opinion that connects your work duties to your condition can overcome it.
The 90-day rule: what §5402 means for your claim
After you file your claim form, the insurer had 90 days to decide. Miss that deadline, and the law presumes your injury is covered. You are also owed up to $10,000 in medical care during the investigation, no matter what.
When you hand in the DWC-1 claim form, §5402 gives the insurer exactly 90 days to accept or deny. If it lets that window close without a formal decision, the law presumes your injury is work-related and covered. The insurer can try to rebut that presumption, but only with evidence it found after the deadline. That is a very hard position for them to defend.
Labor Code §5402(b): "If liability is not rejected within 90 days after the date the claim form is filed under Section 5401, the injury shall be presumed compensable under this division. The presumption of this subdivision is rebuttable only by evidence discovered subsequent to the 90-day period."
During those 90 days, you are not left without care. The insurer must pay up to ten thousand dollars in necessary medical treatment while it investigates. Doctor visits, imaging, physical therapy, and prescriptions your treating doctor orders are all covered during that window. The insurer cannot pause your care while it makes up its mind. If it refused to authorize treatment during the investigation, those costs may still be owed to you.
Pull out your DWC-1 filing date right now. If more than 90 days passed before a formal decision arrived, call us. You may have a presumption working in your favor today.
Denied treatment vs. a denied claim: two different fights
Denied treatment goes through a medical review process with a 30-day deadline. A denied claim goes before a workers' comp judge. Which path you take depends on which type of denial you received.
Not all denials are the same kind. Knowing which type you have tells you where to go and how fast you need to move.
If your treatment was denied (the insurer's reviewer said your MRI, surgery, injections, or physical therapy isn't needed), the appeal goes through Independent Medical Review. A doctor with no financial tie to the insurer reviews your records against state treatment guidelines. That doctor's decision is binding. You have 30 days from the denial to start this process. Chino Hills warehouse pickers and Shoppes retail workers see UR denials for imaging and physical therapy constantly. Every one of those denials is worth appealing.
If your whole claim was denied (the insurer says your injury is not work-related at all), the dispute goes before a workers' comp judge at the San Bernardino WCAB. If the judge's ruling goes against you, you can challenge it by filing a Petition for Reconsideration (a written request asking the board to re-examine the decision). If the board also rules against you, you can ask the Court of Appeal to review that decision. And if your condition gets worse after a case closes, you may be able to reopen it within five years of the injury date.
The deadlines for each route are strict and short. Missing one can permanently end your ability to appeal. That is why calling a lawyer the day you get the denial letter is not optional.
How long do you have to respond?
The shortest deadline is 20 days for an electronically served judge's ruling. Know your deadline before you do anything else. A free call gives you a clear answer fast.
| 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 | Challenge on narrow grounds only (fraud, bias, conflict of interest) | 30 days | §4610.6 |
| A judge's Findings and Award | Petition for Reconsideration (written request for the board to re-examine the ruling) | 25 days if mailed; 20 days 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 |
These deadlines are firm. A judge will not extend them because you were unaware. If you are unsure which deadline applies to your denial, call (661) 273-1780. We will tell you exactly where you stand, for free.
What to do the day your denial letter arrives
Read the stated reason. Save the letter and envelope. Keep your medical appointments. Call a lawyer that day. Every hour you wait is time off your deadline.
Move through these steps as soon as the letter arrives:
Read the stated reason. The insurer must explain why it denied your claim. That reason tells your lawyer which path to take and which evidence will help most.
Save the envelope. The postmark date matters. A Chino Hills stockroom worker or a Peyton Drive delivery driver who tosses the envelope can lose proof of when the appeal window opened.
Keep your medical appointments. If your treating doctor has authorized ongoing care, keep going. A denial of the claim does not always cut off approved treatment, particularly if the 90-day window has already closed on the insurer.
Call a lawyer that same day. At Yazdchi Law, we review denial letters at no charge and tell you what the reason means, what can be done, and which clock is running right now.
If your employer punishes you for pushing back on the denial, act immediately. Cutting your shifts, moving you to a worse position, or firing you for fighting your claim is illegal. The anti-retaliation law gives you the right to get your job back, recover lost wages, and add a penalty to your award. Tell us the same day it happens.
What does a Chino Hills workers' comp denial lawyer cost?
Nothing up front. Nothing unless we win. The WCAB judge sets the fee at the end, usually 12 to 15 percent of what we recover.
You pay nothing to start and nothing by the hour. In California workers' comp, the WCAB judge sets the attorney fee at the close of the case, usually 12 to 15 percent of what we recover for you. If there is no recovery, you owe no fee. A Chino Hills retail associate fighting a denied claim gets the same quality of legal help as any other injured worker, whatever their financial situation.

Tap to call →Denied-claim hearings at the San Bernardino WCAB
Chino Hills denial disputes are heard at the San Bernardino district office. Eman Yazdchi appears there regularly for retail, warehouse, and dairy workers from this area.
Where is the San Bernardino WCAB, and who does it cover?
Workers' comp hearings for Chino Hills are held at the San Bernardino district office of the Workers' Compensation Appeals Board, at 464 W 4th St, San Bernardino, CA 92401. The district covers Chino Hills, Chino, Ontario, Rancho Cucamonga, Fontana, Upland, Rialto, Colton, and the rest of San Bernardino County. Yazdchi Law appears at the San Bernardino WCAB regularly on denied-claim matters, treatment-denial appeals, and 90-day presumption disputes. Related: Chino Hills workers' comp overview and San Bernardino workers' comp.
Which Chino Hills industries produce the most denied claims?
Three groups make up most of the denied-claim matters we handle from Chino Hills at the San Bernardino WCAB:
- Retail and commercial workers: Stockroom associates, maintenance staff, and customer-service employees at the Shoppes at Chino Hills and the surrounding commercial strip. Repetitive-strain and slip-and-fall injuries in retail settings are frequently denied on pre-existing-condition grounds when symptoms built up over time rather than from a single event.
- Logistics and warehouse workers: Pickers, packers, and delivery drivers at fulfillment centers and warehouses along Peyton Drive and near the 71 freeway. Insurers often deny these back, shoulder, and knee claims by arguing the injury predates the current job or by attributing normal wear to age rather than to the work itself.
- Dairy and agricultural workers: Workers at Chino Valley dairy operations face animal-handling injuries and cumulative wear on shoulders, wrists, and backs. Cumulative-trauma denials are common because the damage builds over years. The insurer calls it aging; the law lets you call it your job.
Whatever your industry in Chino Hills, if your claim was denied, the same tools are available to you at the San Bernardino WCAB.
The 90-day presumption in San Bernardino County
One pattern we see often at the San Bernardino WCAB is the insurer that drags out the investigation without ever formally deciding. A Chino Hills retail worker or dairy employee may not realize the 90-day window has passed and the law now presumes their claim is covered. Checking the DWC-1 filing date against the formal denial date is the first thing we do on every new call. Sometimes the fight is already tilted in your favor before we even get to the hearing room. That is a good feeling to share with a scared worker who thought the denial was the end.

Frequently Asked Questions
What happens if the insurer missed the 90-day deadline to decide my Chino Hills claim?
If more than 90 days passed from the date you filed the DWC-1 claim form without a formal acceptance or denial, California law presumes your injury is covered. The insurer can try to rebut that presumption, but only with evidence it found after the deadline. That is a hard position for them to be in. Check the date on your claim form and the date on the denial letter. If the math shows a delay past 90 days, call us right away. We can verify whether the presumption applies and what it means for your case at the San Bernardino WCAB.
What does the $10,000 in interim medical care cover during the 90-day investigation?
While the insurer investigates your claim, it owes up to ten thousand dollars in necessary medical treatment. That covers doctor visits, imaging like MRI or X-ray, physical therapy, specialist referrals your treating doctor orders, and prescriptions. The insurer cannot freeze your care while it decides. If it refused to authorize treatment during that investigation period, it may owe those costs retroactively. A Chino Hills warehouse worker who needed an MRI during the wait should not have paid out of pocket. Call us to find out what you are still owed.
What are the most common reasons a Chino Hills workers' comp claim gets denied?
The four we see most often from Chino Hills workers are: (1) the insurer says the injury was not work-related; (2) it blames a pre-existing condition, pointing to an old MRI or a prior injury; (3) it claims you reported too late and missed the 30-day notice window; or (4) it calls the treatment your doctor ordered not medically necessary. Each of these is a legal position you can challenge, not a final ruling. Pre-existing-condition denials are especially common for retail and dairy workers in Chino Hills whose injuries build up over time. We handle all four types at the San Bernardino WCAB.
Can my employer fire me for fighting a denied workers' comp claim?
No. Terminating you, cutting your hours, moving you to a worse shift, or punishing you in any way for pursuing a denied claim is illegal. You can be reinstated, recover your lost wages, and receive an additional penalty added to your award. If your employer at the Shoppes at Chino Hills, a local distribution center, or a Chino Valley dairy retaliates after you push back on a denial, tell us immediately. These claims have their own deadlines, so acting fast matters.
What is the difference between a denied treatment and a denied claim?
A denied treatment means the insurer's review process said your doctor's requested care isn't needed. That could be a surgery, an MRI, physical therapy, or injections. You fight that through Independent Medical Review, within 30 days of the denial. A denied claim means the insurer says your injury isn't work-related at all. That dispute goes before a workers' comp judge. The routes, the deadlines, and the evidence you need are completely different. We help you figure out which type of denial you have and which path gives you the best shot.
How long do I have to appeal after a workers' comp judge rules against me?
If a judge issued a Findings and Award that went against you, you have 25 days from the date it was mailed (or 20 days if it was served electronically) to file a written request asking the appeals board to re-examine the ruling. After that, if the board also rules against you, you have 45 days to ask the Court of Appeal to review the board's decision. Both windows are firm. A Chino Hills worker who misses the first deadline loses the right to the second one. Do not wait to call.
Can I fight a workers' comp denial if I am undocumented?
Yes. California workers' comp covers every employee regardless of immigration status. A Chino Hills dairy worker, a warehouse picker, or a retail associate has the same right to challenge a denial as anyone else. Your employer cannot threaten to report your immigration status to pressure you into accepting the denial or dropping the fight. That threat is its own violation of California law. Our office is bilingual and welcomes workers from all backgrounds. Your status does not affect your rights here.
What if my condition got worse after my workers' comp case was already closed?
You may be able to reopen your case. A Petition to Reopen is available within five years of the date of injury if your condition worsens or new disability appears. The five-year clock runs from the injury date, not from when the case closed or settled. A Chino Hills worker whose old shoulder or back injury has gotten significantly worse should not assume the door is shut. Call us with your injury date and we will tell you right away whether the window is still open.
