Workers' Comp Claim Denied in Castaic? Get Help Now

Was your Castaic claim turned down? Here is what to do.

Check the denial date, read the stated reason, and call a workers' comp lawyer right away. Your appeal window is short and strict.

Every denial letter must state a reason. Common reasons include: the injury was not work-related in the insurer's view, a pre-existing condition caused the problem, you reported too late, or the treatment is not medically necessary by their standard. Each of those reasons has a legal counter. None of them is a final answer.

Here is what many denied Castaic workers do not know: if the insurer waited more than 90 days after you filed your claim form to send that denial, the law may already treat your injury as covered. That timing check alone can change the entire fight.

The 90-day rule: what the law means for your claim

After you file your DWC-1 claim form, the insurer has 90 days to accept or deny. Miss that window and California law presumes the injury is covered. During those 90 days, they owe you up to $10,000 in medical care regardless of their decision.

This is the most powerful protection California workers have after a denial. After you file your DWC-1 claim form (your official workers' comp claim form) with your employer, the 90-day clock starts. If the insurer does not formally deny within that window, the law flips the presumption in your favor.

Labor Code §5402(b): "If liability is not rejected within 90 days after the date the claim form is filed with the employer pursuant to Section 5401, the injury shall be presumed compensable under this division."

In plain language: if they do not say no within 90 days, they cannot easily say no later. The burden shifts to them to convince a judge that the presumption does not apply.

And here is another part of that same rule: even while the insurer is still investigating, before they have made any decision at all, you are owed up to $10,000 in medical care immediately. They cannot freeze your treatment while they make up their mind. That interim protection covers doctor visits, imaging, prescriptions, and specialist referrals your treating doctor orders.

If the insurer sent your denial after 90 days, or refused medical care during the investigation period, call us at (661) 273-1780. We check those dates free of charge and use the law to your advantage.

Why do insurers turn down workers' comp claims?

Four reasons cover most denials: not work-related, a pre-existing condition, late reporting, or treatment not medically necessary. All four can be challenged with the right evidence.

Knowing which type of denial you received shapes the fight you will run. Here are the four most common reasons and what each one means for your case:

They say the injury is not from work

This is the most contested denial reason. The insurer arranges for a doctor to review your records and say the cause is personal, not job-related. A trucker on the Grapevine gets told the neck pain is from sleeping wrong, not from years in the cab of a rig. A Six Flags ride operator gets told the knee gave out from personal wear, not from thousands of miles on concrete floors. You have the right to your own medical evaluation. Their hired doctor is not the last word.

They blame a pre-existing condition

A prior injury, old arthritis, or earlier imaging does not end your claim. California law only requires that your job contributed to the condition. Even if your shoulder was already worn down, if loading packages on Castaic Road made it worse, you may still have a claim. The insurer must prove the exact split between work and prior condition. Pointing at old records is not enough.

They say you reported too late

You have 30 days to notify your employer after an injury. But for conditions that build up over time, like a repetitive-stress wrist from data entry or a lower back worn down from concrete work, the clock does not start on a single day. It starts when a doctor first connects the condition to your job. Many late-notice denials on build-up claims fall apart under scrutiny.

They say the treatment is not medically necessary

This type of denial runs through a separate medical review process. Your treating doctor orders an MRI or a surgery consult. An insurer-hired reviewer says it does not meet their criteria. That decision can be taken to an independent medical reviewer outside the insurer's control. The deadline is short, so you must act quickly.

Denied treatment vs. a denied claim: two different fights

A denied treatment goes through a medical review track. A denied claim or a bad judge ruling goes through a legal appeal track. Using the wrong path wastes time and rights.

When workers say "I was denied," they often mean one of two very different things. Getting clear on which one you have shapes everything that comes next.

A denied treatment means your main case is open but the insurer turned down something specific your doctor ordered, like an MRI, a surgery referral, or physical therapy. That denial goes first to Utilization Review inside the insurer's system, then to Independent Medical Review. IMR is run by an independent organization, not the insurer. The reviewer checks your file against the state's treatment guidelines and either overturns or upholds the denial. An IMR decision in your favor is binding. The insurer must cover the treatment. You have 30 days from the Utilization Review denial to request IMR. That window is firm.

A denied claim means the insurer says your injury is not covered at all. Or you went to a hearing and the judge ruled against you. That fight goes through a Petition for Reconsideration, which is a written request to the full Workers' Compensation Appeals Board (WCAB) panel asking them to review the judge's ruling. You have 25 days from a mailed decision, or 20 days if the decision was sent electronically. After reconsideration, if you are still losing, you can take the matter to the California Court of Appeal through a Writ of Review.

How long do you have to respond to a denial?

Treatment denials: 30 days. Judge decisions: 25 days mailed or 20 days electronic. A closed case can often be reopened within 5 years. Every window is hard; missing one can end your rights.

These deadlines do not move. Courts make exceptions only in extreme situations. Here is the full appeal timeline for Castaic workers:

What to do the day your denial letter arrives

Keep the letter, note every date, keep seeing your doctor, and call a workers' comp lawyer the same day. Waiting costs you time and evidence.

A denial letter can stop you cold. Here is how to move through it calmly and protect yourself:

• Keep the original letter and envelope. The postmark and the letter date both matter for your deadline. Take a phone photo as a backup right now.
• Write down the stated reason. You will challenge that specific argument, not just "the denial." Knowing the reason shapes your entire response strategy.
• Do not call the insurer's investigator without counsel. Every statement you make becomes part of the record. Let your lawyer handle those conversations.
• Keep going to your doctor. Gaps in treatment give the insurer an argument that you were not seriously hurt. Attend every appointment and document what the doctor tells you.
• Talk to coworkers who know what happened. Witnesses who saw the incident, know the working conditions, or saw you after the injury can help your case at the Van Nuys WCAB.
• Call Yazdchi Law at (661) 273-1780. We handle denied-claim appeals at the Van Nuys WCAB. There is no fee unless we win. One call tells you exactly where you stand.

The insurer has a team working your denial from the moment it was issued. You deserve your own team working just as hard in the other direction.
