Workers' Comp Claim Denied? Your Three Options

A Denial Is Not the End

If your workers' comp claim was denied, you are not alone. Insurers deny legitimate claims routinely — sometimes because they have a factual basis to dispute liability, sometimes as a delay tactic, and sometimes on questionable grounds. In every case, a denial letter is the beginning of a fight, not the end of one.

The key thing to understand about a denial in California is that the carrier is on a clock. California Labor Code §5402(b) provides that if liability is not rejected within 90 days of the date the DWC-1 claim form is filed, the injury is presumed compensable, and the presumption can be rebutted only by evidence discovered after the 90-day period^[1]. A late denial, or a denial based on facts the carrier had within the first 90 days, often cannot survive litigation.

"If liability is not rejected within 90 days after the date the claim form is filed under Section 5401, the injury shall be presumed compensable under this division."

— California Labor Code §5402(b)

You have three primary paths to challenge a denial. Most cases use a combination.

Read the Denial Letter Carefully

Before you choose a path, understand exactly why the carrier says it is denying. The denial letter must state the basis. Common stated reasons:

• AOE/COE: The injury did not arise out of and in the course of employment
• Late report: You did not report within 30 days under §5400
• Pre-existing condition: The condition predates employment
• Statute of limitations: More than one year has passed from the date of injury
• Independent contractor: You were not an employee
• Medical opinion: A doctor (often hired by the carrier) opined the injury is not work-related or not as severe as claimed

Each of these has a different counter-strategy. Save the denial letter, the envelope (for the postmark), and any attachments.

Option 1: File an Application for Adjudication of Claim

This is the formal path to challenging a denial. You file an Application for Adjudication of Claim with the Workers' Compensation Appeals Board (WCAB), starting the litigation process.

What happens next:

• A case number is assigned and venue is set in the WCAB district office that has jurisdiction
• Both sides conduct discovery — medical records, depositions of you and witnesses, prior claim files, and a panel-QME or AME under §§4060–4062
• A Mandatory Settlement Conference is scheduled
• If the case does not settle, a trial (hearing before a workers' comp administrative law judge) is held
• Either side can petition for reconsideration to the WCAB and ultimately seek review in the California Court of Appeal

Timeline: WCAB proceedings can take months to years depending on complexity and the local board's schedule. Most cases settle during the process.

Deadline: Generally one year from the date of injury under California Labor Code §5405, with extensions in §5410 if benefits have been paid. The §5412 date-of-injury rule for cumulative trauma can extend this where you did not yet know the condition was industrial^[2]. Do not wait.

Option 2: Use the QME Process to Challenge the Medical Basis of the Denial

Many denials rest on a medical opinion — often from a doctor selected by the carrier — that your injury is not work-related or is not as severe as claimed. You can challenge this through the QME process. California Labor Code §§4060 and 4062.2 govern QME panels for medical-legal evaluations in disputed cases; the represented worker and the carrier each strike one of three names from the DWC-issued panel, and the remaining QME's report typically supersedes the carrier-doctor's opinion^[3].

When does going through the QME process make sense as a first move?

• When the denial is based on a single defense medical examination, and the QME process can replace that opinion with an independent one
• When the denial is on causation and you have a strong treating physician's report supporting industrial causation
• When the denial is on extent of injury rather than whether it happened

The QME path and the WCAB path are not mutually exclusive. In most cases, filing an Application opens up the QME process within the litigation track.

Option 3: Request Reconsideration from the Insurer

Before formal WCAB proceedings, you can send the insurer a written demand for reconsideration — presenting additional evidence, clarifying facts, or pointing out errors in the denial letter.

When this works:

• When the denial is based on missing documentation (an unreported injury, a missing DWC-1) and you can supply it
• When the insurer simply failed to review records that exist
• When there is a factual misunderstanding that the right document can clear up

When it does not work:

• When the carrier has made a deliberate decision to deny on policy or strategy grounds
• When the dispute is medical-legal rather than factual
• When the carrier needs the leverage of WCAB litigation before it will move

Many denials include language designed to discourage further action. An attorney can tell you honestly whether your denial is worth fighting and which path gives you the best outcome.

What About Medical Treatment While the Denial Is Pending?

Even with a denial, you have rights. California Labor Code §5402(c) requires the carrier to authorize up to $10,000 in medical treatment from the date the DWC-1 is filed until the claim is accepted or rejected — meaning you should have access to care during the investigation period regardless of whether the claim is ultimately denied^[4]. If the carrier is refusing this care, that refusal itself is a basis for WCAB intervention.

Watch for §132a Retaliation

If your employer fired you, demoted you, cut your hours, or otherwise retaliated against you for filing the comp claim, you may have a separate claim under California Labor Code §132a. A §132a claim can support a 50% increase in compensation, reinstatement, back pay, and attorney's fees, and is litigated alongside the underlying comp claim at the WCAB^[5]. Document any adverse employment action that follows your injury report.

What You Should Do Right Now

1. Read your denial letter carefully and identify the stated reason for denial
2. Note any deadlines mentioned
3. Save copies of every communication with the carrier and the employer
4. Continue to seek medical treatment — gaps are used against you
5. Do not give a recorded statement to the carrier without legal advice
6. Contact a workers' comp attorney before responding to the insurer

Initial consultations at most workers' comp firms are free. California workers' comp attorney fees are paid only on recovery and are subject to WCAB judge approval — there is no out-of-pocket cost to consulting an attorney.
