A denial is not the end. It is the beginning of the fight for your benefits.
If your workers' comp claim was denied, you may feel like the system has already decided against you. It has not. An insurer denial is a business decision, not a court ruling. It can be challenged. Whether you care for patients at LAC+USC Medical Center, work a kitchen on Cesar Chavez Avenue, or pack freight on Sixth Street, California law gives you a real path to push back.
You do not have to face this alone. The appeal windows are short. The rules are strict. But the path is clear, and a Certified Specialist can walk it with you for free.
Three things to do right now:
Read the denial letter, write down the reason and the date it was sent, and call a Certified Specialist before the appeal window closes. Most deadlines run 20 to 30 days from the letter.
A denial letter can feel like a wall. It is actually a door. California gives you specific steps to walk through it. But those steps have tight time limits. The day you get that letter is the day to start moving.
There are two kinds of denial: a denied treatment and a denied claim. Each one has its own appeal path and its own deadline. Knowing which kind you have shapes every step that follows.
The four most common reasons: they say the injury did not happen at work, they blame a pre-existing condition, you reported too late, or the treatment was not medically necessary. Each reason has a legal counter-argument.
Insurance companies do not deny claims at random. They use specific reasons because each reason points to a legal standard they think you cannot meet. Knowing their argument is the first step to beating it.
Here are the four reasons we see most often in Boyle Heights files:
None of these reasons is a final word. They are arguments. We make counter-arguments, and most of the time we win when the facts support you.
After you file your DWC-1 claim form, the insurer has 90 days to accept or turn it down. If they miss that window, the law presumes your injury is covered. During those 90 days, they owe you up to $10,000 in medical care right now.
This is the rule most injured workers never hear about, and it is the spine of every denied-claim fight.
When you hand in the DWC-1 form, a clock starts. The insurer has 90 days to accept or turn down your claim. If they let that clock run out without deciding, the law flips in your favor: your injury is presumed covered. They then have to prove it is not work-related, instead of you having to prove it is.
Labor Code §5402(b): "If liability is not rejected within 90 days after the filing of the claim form, the injury shall be presumed compensable under this division."
Even during the investigation period, you are protected. While the insurer decides, they owe up to $10,000 toward your medical care. That means the aide at LAC+USC who hurt her back moving a patient, the cook on Cesar Chavez who burned his hand, and the packer on Sixth Street with a torn shoulder all have a right to a doctor visit, imaging, and prescriptions while the insurer takes its time. They cannot freeze your treatment just because they have not closed their file.
If the insurer waited more than 90 days and is only now denying you, bring that to us immediately. A missed deadline is a powerful foundation for your fight.
A denied treatment goes to an Independent Medical Review, where a neutral doctor decides if the care was needed. A denied claim goes to the Workers' Compensation Appeals Board. The deadlines and processes are completely different.
Mixing up these two paths is one of the most common mistakes injured workers make. If you send your denial to the wrong process, you can lose your right to appeal.
When the insurer's review team turns down a surgery, scan, or therapy your doctor ordered, you can request an Independent Medical Review (a second-opinion process run by a state-approved organization). A neutral doctor reads your records and the state treatment guidelines. Then they rule on whether the care was medically necessary. You have 30 days from the denial notice to file that request.
If the independent review agrees with the insurer, your options become very narrow. You can only challenge that ruling on specific grounds: fraud, a conflict of interest, or a clear mistake of fact. The independent review is designed to be the final word on treatment necessity in most cases.
When the insurer says your injury is not covered at all, the fight goes to the Workers' Compensation Appeals Board. You or your attorney file a Petition for Reconsideration (a written request asking the judge to review the decision again). The deadline is 25 days from a mailed notice or 20 days from an electronic one. If the board rules against you again, the next step is a Writ of Review to the Court of Appeal (a court filing asking an appellate judge to look at the board's decision) within 45 days.
A closed case is not gone forever. If your injury gets worse or new disability appears after a case closes, you can file a Petition to Reopen (a formal request asking the board to reconsider your case because your condition changed) within five years of your original injury date.
Deadlines range from 20 to 45 days depending on what was denied and how the notice was sent. The table below lists every deadline and the law behind it.
Workers lose winnable cases every year by missing these windows. Save this table.
| 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 on narrow grounds (fraud, bias, conflict of interest) | 30 days | §4610.6 |
| A judge's decision (Findings and Award) | Petition for Reconsideration | 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 |

Read it, note the stated reason and the mailed date, pull your records together, and call a lawyer the same day. The clock starts when the letter is sent, not when you open it.
The day the denial letter lands is the most important day in your case. Here is the order of steps:
If your employer took any action against you after you filed your claim, tell us about that on the first call. Firing, cutting hours, or changing your schedule because you filed a workers' comp claim is illegal retaliation under California labor law. You may be entitled to get your job back, your lost wages, and a penalty added to your award. You do not have to accept that treatment silently.

Tap to call →Boyle Heights denial cases are heard at the Los Angeles district office of the Workers' Compensation Appeals Board at 320 W. 4th Street, Los Angeles. Yazdchi Law appears there regularly on hospital, restaurant, and warehouse cases from the neighborhood.
If your Boyle Heights workers' comp claim is denied, the formal fight takes place at the Los Angeles WCAB, 320 West 4th Street, Los Angeles. The district office handles claims from across the east side of the city. Once your attorney files an Application for Adjudication of Claim, the case gets a conference date. At that conference your lawyer lays out the challenge to the denial. From there the case moves toward a hearing where the denial is litigated before a judge. Yazdchi Law appears at this board regularly on files from the hospital, food-service, and warehousing industries serving Boyle Heights workers. Related: Los Angeles denied-claim overview and East LA workers' comp claims.
Three work sectors drive most of the denied-claim files we see from this neighborhood:
Boyle Heights is a deeply Spanish-speaking community. Yazdchi Law handles cases in both English and Spanish. Language should never be a reason to accept a denial that is not right.
California workers' compensation protects every employee in the state, regardless of immigration status. Undocumented workers at LAC+USC, on Cesar Chavez, and on Sixth Street have the same right to fight a denial, collect medical benefits, and recover wage payments as any other employee. Your employer cannot threaten to report your immigration status to pressure you into dropping your claim. That threat is its own separate violation of California labor law. If it happens, tell us about it on your first call.
Yazdchi Law has represented hundreds of California workers in denied-claim and appeal matters at the Los Angeles WCAB and boards across the state. Our 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 turns on its own facts. What every client gets is a Certified Specialist's attention from the first free call to the last hearing.
Nothing up front. California workers' comp attorney fees are set by the judge, usually 12 to 15 percent of what we recover. If there is no recovery, you owe no fee.
You do not need money to get started. Workers' comp lawyers in California work on a contingency basis. The judge sets the fee when your case resolves, usually at 12 to 15 percent of your recovery. If the case produces nothing, you owe nothing at all. A kitchen worker on Cesar Chavez and a clinical aide at LAC+USC have the same access to a Certified Specialist under that system.
