A denial is not the end. It is the beginning of the fight. If a workers' comp insurer rejected your claim, stopped your checks, or refused the treatment your doctor ordered, you can challenge it. That right is yours, and using it costs you nothing up front.
Maybe you were hurt clearing debris in the Eaton Fire burn zone. Maybe it happened lifting a patient on a Huntington Hospital shift, or working a shop on Lake Avenue. The denial letter feels final. It is not. California gives you clear appeal routes with firm deadlines.
Two deadlines matter most. A denied treatment goes to Independent Medical Review, and you have 30 days to appeal. A bad decision from a workers' comp judge goes to a Petition for Reconsideration. That one is due in 25 days if the ruling was mailed to you. Move fast and you keep every option open.
You can appeal whatever your immigration status, and you pay no attorney fee unless we win. The insurer has lawyers from day one. On an appeal, you deserve the same.
Here is what to do today:
Most likely yes. A rejected claim, a cut-off check, or a refused treatment can each be appealed, as long as you act within the deadline.
A first denial is routine, not the last word. Insurers say no to save money, and they count on you walking away. Many Altadena workers who push back, with the right route and the right records, often get the decision changed. Maybe you were framing a rebuild on a burned lot, or stocking shelves on Fair Oaks Avenue. Either way, a denial you fight is very different from one you accept.
Three things commonly get denied, and each has its own appeal. The insurer can refuse a treatment your doctor ordered. It can reject your whole claim. Or a workers' comp judge can rule against you after a hearing. The route you take depends on which one happened to you.
A denied treatment goes to Independent Medical Review. A denied claim or a judge's bad ruling goes to a Petition for Reconsideration. Each route has its own clock.
When your doctor asks for care, like surgery, an MRI, or physical therapy, the insurer sends the request to utilization review. A reviewer, often a doctor who never examined you, approves or denies it. If they deny it, you do not go in front of a judge. You appeal to Independent Medical Review within 30 days of the denial. An independent physician then checks your records against California's treatment guidelines. That doctor either overturns the insurer or upholds the denial.
Here is the hard part most workers never hear. An IMR result is close to final. Under §4610.6, it is presumed correct. It can be undone only on narrow grounds, like fraud, a reviewer's conflict of interest, or a plainly wrong fact.
Labor Code §4610.6: "The determination of the administrative director shall be presumed to be correct and shall be set aside only upon proof by clear and convincing evidence of one or more of the following grounds for appeal:"
So the 30-day window and a well-built appeal carry real weight. A thin IMR appeal is hard to fix later. A strong one, with current imaging and your treating doctor's clear reasoning, is your best shot at the care you need. We assemble that record for you and file on time.
A different route handles a rejected claim or a judge's decision you believe is wrong. After a workers' comp judge issues a Findings and Award, you can challenge it with a Petition for Reconsideration under §5903. You have 25 days if the decision was mailed to you, and 20 days if it was served electronically. The petition lays out the legal and factual errors in the ruling, point by point.
In Altadena, that petition is filed at the Los Angeles district WCAB. But it is decided one level up, by the seven-member Appeals Board in San Francisco. If the Board rules against you, your next step is to ask the Court of Appeal to review the case, within 45 days. We track each of these dates the day a decision arrives.
What if your case already settled, and your injury later got worse? You may be able to reopen it for new or increased disability. The catch is timing. You have to act within five years of the date you were hurt. This matters for Altadena's rebuild crews, whose back or lung problems can deepen long after a job ends. If your old injury is worse today, do not assume the door is closed.
You file the appeal with your evidence, the other side responds, the WCAB reviews the full record, and a written decision follows. We handle each step for you.
An appeal is mostly paperwork and proof, not a dramatic courtroom scene. For a treatment denial, we file your IMR appeal with your complete medical record, your imaging, and your doctor's written reasons. An independent physician reviews it and issues a written decision. There is usually no hearing at all.
A Petition for Reconsideration works differently. We file the petition with the Los Angeles WCAB. The trial judge can then write a report answering your points. The Appeals Board in San Francisco studies the whole record. It can change the decision, leave it in place, or send the case back for more evidence. Most of this happens on paper. That is why a clear, well-supported petition beats a loud one.
Solid medical proof wins appeals: current imaging, a clear doctor's opinion tying the injury to your job, and a record that fills the gap the insurer found.
Appeals are won on the record, so the strength of your medical evidence decides most of them. A denial usually points to a hole: thin imaging, a vague doctor's note, or a report that never explained its own conclusion. The job is to close that hole before your deadline runs.
Many Altadena appeals turn on a fight over cause. The insurer's panel doctor may blame your bad back on age or old wear, not the rebuild work or the years of patient lifting that truly hurt you. The law does not allow a guess. Under California's apportionment rule, the doctor must explain the how and why of any split in plain medical terms. The Appeals Board, sitting en banc in Escobedo v. Marshalls, made that clear. A report that fails to show its reasoning is not substantial evidence. We use that standard to attack weak opinions on reconsideration.
Not long, so start now. Treatment denials give you 30 days. A judge's decision gives you 25 days if it was mailed. Miss the date and you can lose the right to appeal.
Every appeal route runs on a short clock. The deadline starts the day the decision was served on you, not the day you opened the envelope. That is why the date on the letter is the first thing we check. Use this table to find your route and your deadline at a glance.
| What was denied | Your appeal route | Deadline | Law |
|---|---|---|---|
| Treatment denied at Utilization Review | Independent Medical Review | 30 days from the denial | §4610.5 |
| IMR upheld the denial | Appeal only on narrow grounds (fraud, bias, conflict) | 30 days | §4610.6 |
| A judge's decision (Findings & Award) | Petition for Reconsideration | 25 days if mailed, 20 if served electronically | §5903 |
| Reconsideration denied | Writ of Review to the Court of Appeal | 45 days | §5950 |
| New or worse disability after a closed case | Petition to Reopen | Within 5 years of the injury | §5803 |

Tap to call →Altadena appeals run through the Los Angeles district WCAB, then the Appeals Board in San Francisco. Eman Yazdchi appears at the LA WCAB regularly.
Altadena workers' comp cases are heard at the Los Angeles district office of the Workers' Compensation Appeals Board. It sits at 320 West Fourth Street in downtown Los Angeles. That is where the trial judge rules, and where a Petition for Reconsideration is filed. The petition itself is decided one level up, by the seven-commissioner Appeals Board in San Francisco. If that Board rules against you, the case can move to the California Court of Appeal here in the Second District. Yazdchi Law appears at the Los Angeles WCAB regularly and tracks every appeal deadline the day a decision lands.
The work that fills the foothills shapes the denials we fight here:
The Eaton Fire recovery brought a wave of construction and remediation work to Altadena. With it came a wave of injuries. Insurers covering short-term rebuild crews are quick to deny. They often blame a worker's pain on old wear, not the heavy lifting and toxic dust on the job. We see the same move used against longtime caregivers and hospital staff. Beating it takes a doctor's report that explains cause clearly, and an appeal that holds the insurer to the legal standard. Many rebuild and residential-service workers here are immigrants. The appeal routes protect you the same way, whatever your status. You can also check the state QME directory here.
Nothing up front, and nothing unless we win. The WCAB judge sets the fee, usually 12 to 15 percent of what we recover for you.
You pay us nothing to start, and nothing by the hour. In California workers' comp, the WCAB judge sets the attorney fee. It usually runs 12 to 15 percent of your award or settlement, and only if we recover for you. If your appeal does not win, you owe no fee. A rebuild laborer and a school aide get the same representation as anyone else.
