A denial letter from a workers' comp carrier is not a final answer. It is the start of a process. Most denied California claims have a clear path to reversal, if you move fast and know what to do.
First, Read the Denial Letter
The carrier is required to send a written denial within 90 days of the claim form being filed. The letter must say what specific reason they are denying on. Common reasons:
- AOE/COE denial: they claim the injury did not arise out of and in the course of employment
- Late reporting: they claim you missed the 30-day notice or one-year filing window
- Pre-existing condition: they claim the injury was already there before work caused anything
- Medical evidence insufficient: they claim the doctor's report does not support a work connection
- Independent contractor defense: they claim you were not an employee at all
The reason matters because it tells you what evidence you need to fight back.
Step 1: Get the Right Medical Evidence
Almost every denial we see in LA comes down to medical reporting. Either the treating doctor's report was unclear about causation, or the carrier sent the file to a QME who said the injury was not work-related.
If the case is denied, you can self-procure medical care while the dispute is pending. The carrier is on the hook to reimburse if you win. Most workers do not realize this and stop treating, which hurts both their health and their case.
Step 2: File an Application for Adjudication of Claim
This is the formal document that opens your case at the Workers' Compensation Appeals Board (WCAB). It is one page. Filing it costs nothing. It puts the case in front of a judge and gives you access to the panel QME process, depositions, and a trial date.
Time limit: usually one year from the date of injury, or one year from the last payment of benefits, whichever is later.
Step 3: Get a Panel QME
For unrepresented workers, the Division of Workers' Compensation issues a list of three QMEs in the appropriate specialty. You pick one. The QME examines you, reviews records, and issues a report that becomes the lead medical evidence.
For represented workers, the parties typically agree on an AME (Agreed Medical Evaluator). An AME's opinion usually carries more weight than a single-party QME because both sides chose them.
Step 4: Mandatory Settlement Conference (MSC)
Before trial, the case goes to a mandatory settlement conference at the WCAB office (Van Nuys, Los Angeles, Long Beach, Pomona, Marina del Rey for LA-area claims). A judge mediates. Most cases settle here, but not always at fair numbers if the worker is unrepresented.
Step 5: Trial
If the case does not settle, you get a trial in front of a workers' comp judge. No jury. The judge weighs the medical reports, hears witness testimony if needed, and issues a written decision within 30 to 90 days.
You can appeal a bad decision to the WCAB itself within 20 days (called a Petition for Reconsideration), and from there to the California Court of Appeal.
What to Do This Week
- Save the denial letter. Note the date you received it.
- Keep treating. Self-procure care if you have to. Document every visit.
- Get a complete copy of your medical file from every provider.
- Write down your version of events. Witnesses, dates, conversations with supervisors.
- Talk to an attorney before you sign anything. Workers' comp attorneys in California work on a 15 percent contingency capped by statute, and the fee comes out of the recovery, not your pocket. You should never be asked to pay anything upfront.
Why Denials Get Reversed
In our experience handling LA workers' comp claims, the most common reason a denial gets reversed is simple: a better medical report. The treating doctor writes a clear causation opinion, or the QME comes back finding industrial causation, and the carrier flips. Sometimes it takes a deposition of the QME, sometimes it takes a trial. But the path is usually about evidence, not about luck.
