Claim Denied?
Your Workers' Comp Claim Was Denied — Here's What to Do
A denial is not the end of your case. In California, you have the right to dispute it — and many denied claims are won with the right evidence.
If you opened a denial letter from the workers' compensation insurer, take a breath. A denial is the insurer's position — not a judge's final ruling. California gives you the right to take a disputed claim before the Workers' Compensation Appeals Board (WCAB), and a large share of denials are reversed once the claim is properly developed.
Why claims get denied
- The insurer disputes that the injury is work-related (AOE/COE)
- You reported the injury or filed the claim late
- The claim blames a "pre-existing condition"
- Thin or missing medical documentation
- The employer claims you weren't an employee
- Missed paperwork or a missed deadline
What to do after a denial
- 1
Don't panic — and don't quit treating
A denial letter is the insurer's opening position, not a final ruling. Keep your medical appointments and keep copies of everything.
- 2
Read the denial and note the date
The letter states why the claim was denied and starts important clocks. The date on it matters — deadlines run from specific events.
- 3
Get the claim in front of the WCAB
Disputed claims are resolved by filing an Application for Adjudication of Claim with the Workers' Compensation Appeals Board, then a Declaration of Readiness to Proceed to request a hearing.

Build the medical record
Most denials are won or lost on medical evidence. A qualified medical evaluation (QME, or AME if you're represented) often becomes the turning point.
Deadlines can bar your claim — don't wait
California workers' comp runs on strict time limits, and a denial can start a short clock. Missing a deadline can end an otherwise valid claim. If you've been denied, get the letter reviewed quickly.
Denied-Claim FAQ
How long do I have to dispute a denied workers' comp claim in California?+
Generally, you have one year from the date of injury to file an Application for Adjudication of Claim, with separate, shorter deadlines for specific disputes (for example, treatment denials through Independent Medical Review). Because a denial can start a short clock, it's best to have it reviewed right away.
Can a denied claim really be overturned?+
Yes. Many denied California claims are accepted or won after the right evidence is developed and the dispute is brought before the WCAB. A denial frequently reflects missing documentation rather than a claim that lacks merit.
Does it cost money to appeal a denial?+
We work on contingency — no upfront cost, and attorney's fees in workers' comp are set by the court and paid out of the recovery, not your pocket. The consultation is free.
My medical treatment was denied through Utilization Review. Is that the same as a claim denial?+
No. A treatment denial through Utilization Review is challenged through Independent Medical Review (IMR), on its own deadline, while a full claim denial goes through the WCAB. They're different tracks — and both have time limits.
