Workers' Comp Claim Denied in California? What to Do Next

Why do California workers' comp claims get denied?

Insurers deny California claims for a few common reasons: missed deadlines, disputes over whether the injury is work related, no witnesses, pre-existing conditions, or filing after a firing. The denial letter must state the reasons in writing within 90 days.

Read your denial letter closely. The stated reason shapes your whole appeal. Here are the reasons we see most:

• The insurer says the injury did not happen at work.
• A report or filing deadline passed.
• The insurer blames a pre-existing condition, like an old back problem.
• No one saw the accident happen.
• The claim came after a firing or layoff.
• The company calls you a contractor, not an employee.
• A doctor's report left out key facts.

Every one of these can be fought. A herniated disc can come from years of lifting, not one fall. A rotator cuff tear can build through years of overhead work. Carpal tunnel often has no single accident at all. California covers these cumulative trauma injuries. An old injury made worse by work is still a work injury. And the label on your paycheck does not decide the law. Many workers called contractors are employees under California law.

Start gathering proof now. Ask for a copy of your incident report. Write down the names of coworkers who saw the accident or heard you report it. Save every text and email about the injury. Photos of the job site help too. Request your medical records. Small pieces of proof win these fights. Bring all of it to a lawyer before you answer the insurer.

What is the 90-day rule for denied claims?

Once you file the DWC-1 claim form, the insurer has 90 days to accept or deny the claim. If it misses that deadline, the injury is presumed covered. The insurer must also allow up to $10,000 in medical treatment while it investigates.

This rule comes from Labor Code 5402. The clock starts when you hand in the claim form. A late denial is a weak denial. The law then presumes your injury is covered. The insurer can only fight that with evidence it could not have found earlier.

One example: a Palmdale warehouse worker files a claim form for a shoulder tear. The insurer sits on it for 95 days, then denies. That denial came too late. The claim is presumed covered, and the insurer starts the appeal in a deep hole. We ask the judge to enforce that presumption at the first hearing.

The $10,000 treatment right matters just as much. During the investigation, the insurer must authorize medical care. That can cover doctor visits, an MRI, physical therapy, and medication. Many injured workers never hear about this right. Ask for it in writing, and keep a copy. If the adjuster refuses, that refusal becomes evidence too. Use the money to see a doctor fast. Early medical records anchor the whole claim.

Other deadlines shape a denied claim as well. This table shows the ones that decide most cases.

How do you appeal a denied claim at the WCAB?

You appeal by filing an Application for Adjudication of Claim with the Workers' Compensation Appeals Board. Most workers have one year from the injury date to file. A judge, not the insurer, then decides the case. Urgent disputes can be heard fast.

The Application for Adjudication opens your case at the WCAB. Labor Code 5405 gives most workers one year from the injury date to file it. There is no fee to file it. Filing gets you a case number. It also stops the insurer from running out the clock.

Next comes medical evidence. In a disputed claim, you will likely see a QME. That is a neutral doctor drawn from a state panel. The DWC sends a list of three names. Each side strikes one. The remaining doctor examines you and writes a report. That report often decides the whole case, so exam preparation matters. Bring a list of your job duties and your symptoms. Tell the doctor the full story, start to finish. If you have a lawyer, both sides may agree on an AME instead.

Then you push for a court date. A form called a Declaration of Readiness to Proceed asks the judge to set one. Denied claims often get a priority conference, an early hearing on coverage. The judge puts the case on a fast track from there. Urgent fights over care or checks can get an expedited hearing. Many cases settle at this stage. Insurers respond to pressure, not to patience.

Most denied claims end one of three ways. The insurer accepts the claim after seeing the medical evidence. The case settles, either as a lump sum called a Compromise and Release, or as a stipulated award with ongoing care. Or a judge decides it at trial. A good lawyer makes every one of those paths lead to payment.

What if only your medical treatment was denied?

Treatment denials follow a different path than claim denials. A utilization review doctor can deny a specific treatment request. You then have 30 days to appeal through Independent Medical Review, a state process where a neutral doctor makes the final call.

Say your claim is accepted, but the insurer refuses your MRI or surgery. That refusal comes through utilization review under Labor Code 4610. The denial envelope includes an IMR application. Labor Code 4610.5 gives you 30 days to send it in. IMR costs you nothing. The insurer pays the review fee. Miss that window and the denial usually stands for a year.

Here is the treatment appeal, step by step.

IMR decisions turn on paper. Your doctor's request must track the state treatment guidelines and explain your need. A strong report at the start beats a strong appeal later. Our office works with treating doctors to get the request right the first time. Keep getting care any way you can while you wait. A gap in treatment hands the insurer a new argument. And your doctor can always file a fresh request with better records.
