Can You Reopen a California Workers’ Comp Claim if Your Injury Gets Worse?
Finishing a workers’ compensation case does not always mean your recovery goes as expected. An injury that seemed stable could later cause greater pain or keep you from doing work you had resumed.
California allows some injured workers to reopen their cases for additional benefits. The choices available to you depend on how the case ended and when you seek the change. If your work injury has worsened in 2026, our San Benito County, CA workers’ compensation attorney will explain your options.
What Changes Allow You to Reopen a California Workers’ Comp Case?
Reopening requires a legal basis for changing the earlier award. When an injury gets worse, that basis is often called "new and further disability." This means the original work injury has caused additional disability beyond what the award addressed.
For example, a worker might receive an award for a knee injury, return to work, and later develop greater limitations from that same injury. Medical support connecting the decline to the original injury could support reopening.
The process is not simply a chance to ask for more money because you dislike the earlier result. Your request must explain what changed. A separate injury from a later accident also needs analysis to determine which claim should address it.
Does Your California Workers’ Comp Settlement Allow Reopening?
The type of settlement you signed determines whether you kept the right to seek more benefits.
With a Stipulations with Request for Award, you agree on benefits, and a judge issues an award. This settlement usually allows you to request an increase if the original injury causes additional disability. Medical care also often remains covered.
A Compromise and Release usually ends your right to further benefits in exchange for a lump sum. If it closed the benefits you now need, worsening symptoms alone do not allow you to reopen the claim. You would need a separate legal reason to challenge the settlement itself.
How Long Do You Have to Reopen a California Workers’ Comp Claim?
Under California Labor Code Section 5410, proceedings for new and further disability must begin within five years of the injury date. The period runs from the injury, not from the settlement or the date your symptoms worsen.
For example, settling four years after an injury does not give you another five years to request an increase. Only about one year remains under that timeline.
Telling the insurance adjuster that you feel worse does not replace the required filing. Have the deadline checked promptly, especially if your condition changes near the end of the five-year period.
Do You Need to Reopen Your Case to Receive More Medical Treatment?
If your award already provides future medical care, you do not need to reopen it solely to use that benefit. Your treating doctor should request the care needed for the covered injury through the usual approval process.
The five-year reopening deadline does not automatically end medical rights preserved in an award. However, the requested treatment must still meet the rules for covered care.
How Do You Request Reopening of a California Workers’ Comp Case?
To reopen a workers’ comp case, file a petition with the Workers’ Compensation Appeals Board, or WCAB. Under California Code of Regulations, Title 8, Section 10536, the petition must explain how your disability has increased since the earlier award.
A medical report should address:
- What has changed since the earlier award
- How the original work injury caused the change
- Any new limits on your ability to work
- Whether those limits are temporary or lasting
Your attorney submits the required filing documents and sends copies to the other parties. Keep copies showing what was filed and when. If no WCAB case was previously opened, an Application for Adjudication of Claim is needed to bring the matter before the Board.
What Happens if the California Insurer Disputes Your Request to Reopen a Workers’ Comp Case?
The insurer’s objection does not give it the final decision. An unresolved request can be presented to a workers’ compensation judge. When the case is ready for a hearing, a declaration of readiness asks the Board to schedule proceedings.
The response should address the actual disagreement. If the insurer blames your decline on a later accident, the medical review must examine how each event affected your condition.
Additional payments are not automatic while that dispute continues. The judge must determine whether the requirements for changing the award are met and which benefits are owed.
