A denial is not the end. It’s the beginning of our fight for your benefits.

In California, a denied Burbank workers' comp claim is overturned through the §5402(b) 90-day presumption, an IMR appeal under §4610.5, or a Petition for Reconsideration under §5903 (25 mailed / 20 electronic). Yazdchi Law, a Certified Specialist firm, handles studio lot / Bob Hope Airport denial files at the Burbank WCAB. Request a free case review.
What does a denied Burbank workers' comp claim actually look like? On a Warner Bros set-electrician's cumulative-trauma shoulder case, the denial usually arrives as a §5402 written letter contesting compensability or as silence past the 90-day decision window — silence triggers the §5402(b) presumption-of-compensability rebuttable only by reasonable-diligence evidence the insurer could not have discovered earlier. On a Burbank Bob Hope Airport baggage-handler's lumbar disability claim, the denial often takes the form of a UR cycle under California Labor Code §4610 blocking treatment authorization — routing the appeal to IMR under California Labor Code §4610.5.
Both forms are an adjuster's decision, not a final ruling. The injured Burbank worker disputes either form at the Burbank district WCAB through an Application for Adjudication, with the §5814 25% penalty under California Labor Code §5814 layered on the dated benefit-delay record — TD under California Labor Code §4650 not paid, medical under California Labor Code §4600 not authorized, PD advances under California Labor Code §4658 delayed. On long-tenure studio production, airport-corridor logistics, and Empire-Center retail workers, §4553 50% serious-and-willful exposure under California Labor Code §4553 also surfaces when a Title 8 safety order violation is documented.
Yazdchi Law's office at 1125 W Avenue M-14, Suite A in Palmdale serves the Burbank WCAB on denied-claim files. Eman Yazdchi handles the §5402(b) presumption fight, the §4610.5 IMR cycle, and the §5903 Petition for Reconsideration phase, and is a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California.
A denied Burbank workers' comp claim is built around five California Labor Code sections that do most of the work: California Labor Code §5402(b) (the 90-day decision-window presumption), California Labor Code §4610.5 (Independent Medical Review on UR denials), California Labor Code §5814 (the 25% penalty on unreasonable delay), California Labor Code §5900 (the framework section authorizing reconsideration), and California Labor Code §5903 (the 25-day/20-day Petition for Reconsideration deadline).
Under California Labor Code §5402(b), once an injured Burbank worker files a DWC-1 claim form, the insurer has 90 days to accept or deny the claim. If the insurer misses the 90-day window, the injury is presumed compensable — and that presumption can only be rebutted by evidence the insurer could not have discovered with reasonable diligence during the 90 days. On a Warner Bros set-electrician's cumulative-trauma shoulder case, the §5402(b) presumption is leverage because studio lot / Bob Hope Airport insurers routinely sit on a DWC-1 while waiting on a QME panel under California Labor Code §4062.2 or a UR cycle under California Labor Code §4610 — both of which can blow past the 90-day window. California Labor Code §5402(c) also requires up to $10,000 in immediate medical treatment within one day of the DWC-1, regardless of the 90-day status — a Burbank delay on the §5402(c) duty surfaces a separate §5814 25% penalty.
If the Burbank insurer's Utilization Review under California Labor Code §4610 denies a treatment request — surgery, physical therapy, prescriptions, medical-legal evaluation — the worker appeals through Independent Medical Review within 30 days under California Labor Code §4610.5. An independent physician reviewer reads the medical record against the Medical Treatment Utilization Schedule and either upholds or overturns the denial. The IMR decision is binding except on narrow grounds under California Labor Code §4610.6 — the five enumerated grounds being procurement by fraud, material conflict of interest, bias on a constitutionally protected basis, mistake of fact not subject to expert opinion, or plainly erroneous express or implied finding of fact.
Under California Labor Code §5814, when a California workers' comp insurer unreasonably delays or denies a benefit owed to a Burbank worker, a 25% penalty attaches to that delayed benefit — temporary disability not paid timely under California Labor Code §4650, medical treatment not authorized under California Labor Code §4600, permanent disability advances not paid on schedule under California Labor Code §4658. The penalty applies per benefit unreasonably delayed, not once per case. The Burbank workers' comp judge applies California Labor Code §5814 after a focused evidentiary showing on the dated delay record.
On a Burbank Bob Hope Airport baggage-handler's lumbar disability claim, a Petition for Reconsideration under California Labor Code §5900 is filed at the Burbank district WCAB within 25 days of mail service of the workers' comp judge's adverse decision (20 days if served electronically via EAMS under Title 8 CCR section 10605). On the typical studio lot / Bob Hope Airport denial appeal, the Petition identifies one or more of the §5903 grounds: newly discovered evidence on the studio grip / set-electrician cumulative-trauma, Bob Hope Airport baggage-handler back cases, and Empire-Center retail slip-and-fall files, an unreasonable factual finding on the §5402(b) presumption or the QME apportionment under California Labor Code §4663, or an error of law on the §5402(c) one-day duty or the §5814 penalty record. The WCAB either grants reconsideration and modifies the decision, or denies. A denial opens the Writ of Review path under California Labor Code §5950 within 45 days.

Yazdchi Law appears at the Van Nuys WCAB on Burbank denial appeals regularly, including those that involve the California Labor Code §5402(b) 90-day presumption, the California Labor Code §5814 25% penalty, and the California Labor Code §5903 25-day/20-day Petition for Reconsideration deadline.

A Warner Bros set-electrician's cumulative-trauma shoulder case typically receives the §5402 denial after the §5402(b) 90-day window has run, opening the presumption-of-compensability argument under California Labor Code §5402(b). A Burbank Bob Hope Airport baggage-handler's lumbar disability claim typically receives the denial after a UR cycle under California Labor Code §4610 held the treatment authorization past statute, opening the IMR appeal under California Labor Code §4610.5 plus the §5814 25% penalty on the delay. The studio grip / set-electrician cumulative-trauma, Bob Hope Airport baggage-handler back cases, and Empire-Center retail slip-and-fall files produces a high concentration of these layered-denial files on the Burbank docket.
On a Burbank Bob Hope Airport baggage-handler's lumbar disability claim, the §5402 denial often runs alongside a separate California Labor Code §4553 50% serious-and-willful penalty argument. Under §4553, when the Burbank employer knew of a Title 8 safety order violation and failed to correct it, the worker recovers a 50% penalty on the compensation owed. The studio grip / set-electrician cumulative-trauma, Bob Hope Airport baggage-handler back cases, and Empire-Center retail slip-and-fall files sometimes produces a documented Cal/OSHA Title 8 citation that locks in the §4553 record. Filed at the Burbank WCAB alongside the underlying denial dispute, the §4553 issue often moves the insurer's denial settlement materially.
