Denied Workers’ Compensation Claim Lawyer in Van Nuys

Start With the Denial Letter, Not With an Assumption

The first useful question is not “How do I appeal?” It is “What exactly did the insurer deny?”

A denial letter should identify the claim and explain the claims administrator’s position. Read it with the DWC-1 claim form, medical records and any earlier delay or status letters beside you. The reason given for denial determines what evidence and procedure may matter next.

Common disputes include whether the injury arose out of employment, whether notice or filing was timely, whether the person was an employee, whether medical evidence supports causation, whether a claimed body part is industrial, or whether the insurer believes another legal defense applies.

A reason for denial is an issue to analyze, not proof that the insurer is correct.

A Claim Denial and a Treatment Denial Are Not the Same Dispute

This distinction prevents a common procedural mistake. Not every adverse insurance decision goes through the same “appeal” route.

If the claim itself is denied, California DWC instructs workers who want to contest the denial to file an Application for Adjudication of Claim. If treatment is being denied on an otherwise accepted claim, different medical-review procedures can apply. A dispute over a doctor’s medical opinion may also involve a QME or, when represented, an AME.

If your issue is medical evidence rather than the underlying claim denial, review our Qualified Medical Evaluations page.

What to Do After Receiving a Denial

Take these steps before paperwork and deadlines become harder to reconstruct:

1. Keep the denial letter and envelope. Preserve the date and method of service.
2. Locate your DWC-1 claim form. Keep the copy showing when it was given or mailed to the employer.
3. Build a medical timeline. Include the first treatment, diagnoses, work-status notes, referrals and any record linking the condition to work.
4. Build a work timeline. Identify when and how the injury happened or developed, when it was reported and who was told.
5. Do not ignore QME paperwork. Medical-legal deadlines and selection rules can affect the case.
6. Identify the procedure that applies. A denied claim may require an Application for Adjudication rather than a Petition for Reconsideration.
7. Get help before the deadline, not after it. Workers’ compensation time limits can depend on the specific dispute and procedural posture.

The 90-Day Claim-Decision Rule Can Matter

California DWC states that if a worker files a claim form and the employer does not deny the claim within 90 days, the injury is presumed covered in most cases. The claim form also matters while the insurer investigates: DWC states that appropriate medical treatment must be authorized within one day after filing, up to $10,000 while the claim is being investigated.

That does not mean every claim automatically succeeds on day 91 regardless of facts. But the timing of the DWC-1 and the insurer’s notices can be legally important, which is why workers should keep dated copies rather than relying on memory.

How a Denied Claim Gets Before a Workers’ Compensation Judge

California DWC describes the process in practical steps.

1. File an Application for Adjudication of Claim

   The application opens a case at a DWC district office. It generally must be filed in the county where the worker lives or where the injury occurred, subject to the applicable rules.

2. Receive an ADJ case number

   The DWC sends a notice confirming the filing. The assigned number begins with “ADJ” and should be used on later case documents.

3. Request a hearing when the case is ready

   A Declaration of Readiness to Proceed is used to request a hearing. The case may be set for a mandatory settlement conference before trial issues are resolved.

4. Present evidence to a workers’ compensation judge

   The judge can decide disputed issues after the parties have an opportunity to present evidence and argument. A denied claim is therefore not the same thing as an appeal from a judge’s final decision.

If a workers’ compensation judge has already issued a final decision and you need to challenge that decision, see our Workers’ Compensation Appeals page.

What Evidence Can Change the Direction of a Denied Claim?

The answer depends on the reason for denial. Useful evidence may include:

• the DWC-1 and proof of when it was submitted;
• the employer’s injury report or supervisor communications;
• emergency, urgent-care and treating-physician records;
• a clear description of how the injury happened or developed;
• work restrictions and disability slips;
• witness information when a specific incident is disputed;
• timecards, schedules or job descriptions when work activity matters;
• medical-legal reports from a QME or AME when causation is disputed; and
• prior medical records when a pre-existing condition has been raised.

Do not hide prior treatment or conditions. An inaccurate medical history can create a credibility problem in addition to the medical dispute already in the case.

Denial Based on a Pre-Existing Condition

A prior condition does not automatically establish that a later work injury is non-industrial. The medical evidence may need to distinguish a new specific injury, a cumulative injury, an aggravation, or other causes.

The important question is what the competent medical evidence says about causation. That is one reason QME or AME reports can become central in disputed claims.

When to Talk With a Workers’ Compensation Lawyer

Legal advice is particularly useful when the denial raises medical causation, cumulative trauma, a post-termination claim, a disputed employer relationship, conflicting medical reports, a QME issue, significant wage loss, permanent disability or an approaching hearing.
