By Eman Yazdchi, Esq. · Certified Specialist in Workers' Compensation Law, State Bar of California Board of Legal Specialization
In California, a Van Nuys workers' comp appeal runs through Petition for Reconsideration under Labor Code §5903 (25 days mailed / 20 electronic) plus an IMR cycle under §4610.5 on UR treatment denials. Yazdchi Law, a Certified Specialist firm, files §5903 Petitions and §5814 25% penalty claims on Van Nuys files. Request a free case review.
Van Nuys appellate leverage starts with the §4663 apportionment fight. Insurer-QMEs under California Labor Code §4062.2 typically inflate non-industrial causation on long-tenure healthcare, Van Nuys Airport / Sherman Way hospitality, and SFV warehouse workers; the worker's panel-QME or supplemental medical-legal report under California Labor Code §4062.1 challenges with the Valley Presbyterian patient-handling spinal cases, Van Nuys Airport ground-handler back injuries, and Sherman Way restaurant back cases medical record. A 15-20 point apportionment swing on a 60% PD rating under California Labor Code §4660 moves the indemnity by mid-six-figures. The §5903 Petition for Reconsideration (25 days mailed / 20 electronic) preserves the §4663 issue when the WCJ adopted the insurer-QME finding.
Layered with the §4663 attack: the §5402(b) 90-day presumption (when the insurer let the decision window run), the §5814 25% penalty under California Labor Code §5814 on the dated benefit-delay ledger, and the §5950 Writ of Review when the WCAB denies the Petition. On a Valley Presbyterian Hospital ICU nurse's patient-handling lumbar case, the Petition typically presents all four issues together. The Writ runs 45 days from WCAB service; the standard of review is errors of law, not factual disputes.
Yazdchi Law's office at 1125 W Avenue M-14, Suite A in Palmdale serves the Van Nuys WCAB docket on appellate matters. Eman Yazdchi appears at the Van Nuys district office of the Workers' Compensation Appeals Board for appeal preparation and oral argument, and is a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California.
A Van Nuys workers' comp appeal runs through three layered procedures, each with its own deadline and standard: Independent Medical Review under California Labor Code §4610.5 for UR treatment denials; Petition for Reconsideration under California Labor Code §5900 and California Labor Code §5903 for WCJ decisions; and Writ of Review under California Labor Code §5950 for further appeal to the Court of Appeal.
On a Valley Presbyterian Hospital ICU nurse's patient-handling lumbar case, the appeal path almost always starts with a Utilization Review denial — usually of a lumbar MRI, an epidural injection, or a cervical/lumbar fusion request under California Labor Code §4610. The worker has 30 days from the UR decision to appeal through Independent Medical Review under California Labor Code §4610.5. An independent physician reviewer (assigned through Maximus, the DWC-designated IMR vendor) reads the medical record against the Medical Treatment Utilization Schedule and either upholds or overturns the UR denial. The IMR ruling is binding except on the five narrow grounds under California Labor Code §4610.6 — fraud, material conflict of interest, bias on a constitutionally protected basis, mistake of fact not subject to expert opinion, or a plainly erroneous express or implied finding of fact. On the Van Nuys docket, IMR is the only route around a UR treatment denial.
A Petition for Reconsideration under California Labor Code §5900 is the appeal of a workers' comp judge's final decision to the Workers' Compensation Appeals Board. The deadline under California Labor Code §5903 is 25 days from service of the decision by mail (20 days if served electronically via EAMS under Title 8 CCR section 10605). The Petition must identify the grounds under §5903 — newly discovered evidence, fraud, the workers' comp judge acting without or in excess of powers, an unreasonable factual finding, an error of law, or insufficient or excessive findings. The WCAB either grants reconsideration and modifies the decision, or denies the Petition.
A Writ of Review under California Labor Code §5950 is the further appeal of the WCAB's decision on the Petition for Reconsideration to the California Court of Appeal. The deadline is 45 days from the date of service of the WCAB's order. The standard of review on writ is narrow — the Court of Appeal reviews errors of law and constitutional questions, not factual disputes. A writ of review is a discretionary remedy; the Court of Appeal can summarily deny without opinion. The cases that succeed on writ typically involve a substantive error of law that conflicts with controlling precedent.
Under California Labor Code §5814, the 25% penalty attaches per benefit unreasonably delayed — temporary disability under California Labor Code §4650 paid late, medical treatment under California Labor Code §4600 not authorized, permanent disability indemnity under California Labor Code §4658 held back. On a Van Nuys Airport ground-handler's cumulative-trauma shoulder claim, the §5814 penalty exposure is layered: TD checks held during the §5402(b) decision window, surgery or imaging held through repeated UR cycles, and PD advances under §4650 delayed pending the WCJ's permanent disability finding. A Van Nuys Petition for Reconsideration under California Labor Code §5903 can raise every §5814 trigger in the same filing — the §5814 record is built on the Valley Presbyterian patient-handling spinal cases, Van Nuys Airport ground-handler back injuries, and Sherman Way restaurant back cases of the underlying case and the dated benefit-payment ledger.

Tap to call →Van Nuys Petitions for Reconsideration are filed in the case file at the Van Nuys district office of the Workers' Compensation Appeals Board at 15400 Sherman Way, Suite 500, Van Nuys and forwarded to the WCAB en banc reconsideration panel in San Francisco. Yazdchi Law appears at the Van Nuys WCAB on appeals regularly, including Petitions challenging apportionment under California Labor Code §4663, cumulative-trauma date-of-injury under California Labor Code §5412, permanent disability rating under California Labor Code §4660, and California Labor Code §5814 penalty rulings.

A Valley Presbyterian Hospital ICU nurse's patient-handling lumbar case typically arrives at the Van Nuys WCAB on Petition for Reconsideration carrying multiple delayed-benefit triggers — temporary disability under California Labor Code §4650 held past statute, medical treatment under California Labor Code §4600 held through repeat UR cycles, permanent disability advances under California Labor Code §4658 delayed pending the PD rating. Under California Labor Code §5814, the 25% penalty attaches per benefit unreasonably delayed. The Van Nuys appellate strategy on healthcare, Van Nuys Airport / Sherman Way hospitality, and SFV warehouse files usually bundles every §5814 trigger into the same Petition under California Labor Code §5903.
On a Van Nuys Airport ground-handler's cumulative-trauma shoulder claim, the Petition for Reconsideration under California Labor Code §5900 typically attacks the WCJ's substantial-evidence finding on the Valley Presbyterian patient-handling spinal cases, Van Nuys Airport ground-handler back injuries, and Sherman Way restaurant back cases record — the apportionment under California Labor Code §4663, the QME panel under California Labor Code §4062.2, or the occupational-variant call under California Labor Code §4660. The §5903 25-day mailed / 20-day electronic clock starts on WCJ service. A modification or denial opens the §5950 Writ of Review path. The substantial-evidence standard at WCAB level is deferential; the Court of Appeal on Writ reviews only legal errors.
