TIMOTHY FRYE vs. STATE OF CALIFORNIA, DEPARTMENT OF CORRECTIONS AND REHABILITATION, Legally Uninsured; STATE COMPENSATION INSURANCE FUND

This case involves a correctional lieutenant who claimed a cumulative industrial injury to his heart, knees, hip, cardiovascular system, and hypertension. The defendant sought reconsideration, arguing for separate injury periods for orthopedic and internal conditions. The Board denied the petition, upholding the finding of a single cumulative trauma period ending on the applicant's last day of employment. The Board found no evidence that the applicant knew his disability was work-related prior to consulting an attorney, thus establishing the date of injury as post-employment.

Jesus Hernandez vs. JCB CLARK ENTERPRISES INC, U.S. FIRE AND GUARANTY

Here's a summary for a lawyer: The Workers' Compensation Appeals Board denied Jesus Hernandez's petition for reconsideration, affirming the WCJ's decision that he failed to meet his burden of proof for a cumulative trauma injury ending March 17, 2007. The applicant argued that prior injuries and a doctor's report supported his claim for a longer period, but the Board found his arguments unpersuasive. A dissenting commissioner believed the case should be returned for further proceedings on orthopedic cumulative trauma claims due to disputed employment periods and available evidence.

MICHELLE JIMENEZ vs. DENCO SALES COMPANY, ACE PROPERTY AND CASUALTY COMPANY, ARGONAUT INSURANCE COMPANY

This case concerns applicant Michelle Jimenez's claim for additional temporary disability benefits for lumbar spine injuries sustained from a specific injury in July 2007 and a cumulative trauma injury ending in July 2008. The Appeals Board found that while the 2007 injury's temporary disability indemnity limit under Labor Code section 4656(c)(1) expired in August 2009, the applicant is entitled to remaining temporary disability under section 4656(c)(2) for the 2008 cumulative trauma injury. Because the applicant had only received 69 weeks of temporary disability for the cumulative trauma injury and is entitled to 104 weeks within five years of the injury date, she is awarded an additional 35 weeks of temporary disability indemnity prior to July 17, 2013.

ANTONIETA GUERRERO vs. WELLPOINT HEALTH NETWORK, INC., ZURICH LOS ANGELES, CALIFORNIA INSURANCE GUARANTEE ASSOCIATION For FREMONT In Liquidation

The Workers' Compensation Appeals Board granted reconsideration of a prior award due to insufficient analysis by the WCJ regarding the date(s) of cumulative trauma. The Board found the WCJ's decision lacked specific reference to evidence, particularly on whether multiple or a single period of cumulative trauma applied. The matter was returned to the trial level for further proceedings, a new decision, and adequate analysis of all contentions, including permanent disability and apportionment.

KERRY NECHODOM vs. CITY OF GROVER BEACH

The Workers' Compensation Appeals Board granted reconsideration to amend the date of injury for Kerry Nechodom's right shoulder injury in case ADJ6693720 from February 3, 2007 - September 10, 2009 to August 12, 2008 - September 10, 2009. This amendment acknowledges a separate cumulative trauma injury due to distinct periods of disability and lack of continuous treatment between injuries. The Board affirmed the original award, finding that the applicant sustained two separate cumulative trauma injuries causing distinct periods of temporary disability. The employer's arguments regarding the cumulative trauma period and Labor Code $\S 4656$ limitations were addressed and resolved by this clarification.

JAIME LLAMAS vs. CITY OF ANAHEIM, CITY OF DOWNEY

Applicant Jaime Llamas, a police officer, sustained a cumulative brain injury (cancer) while employed by the City of Downey and the City of Anaheim. The WCJ found both employers jointly and severally liable. Defendant City of Downey sought reconsideration, challenging the last injurious exposure and their liability for temporary disability. The Appeals Board granted reconsideration, rescinded the original Findings and Award, and substituted new findings. The Board confirmed the cumulative injury, clarified employment periods, affirmed the industrial presumption for both employers, established a specific liability period (December 21, 2016, through December 21, 2017) based on medical evidence of latency, and deferred issues of contribution between the employers.

ZENAIDA AVILES vs. PIH HEALTH HOSPITAL, ATHENS ADMINISTRATORS

Applicant sought reconsideration of a Joint Findings and Award that denied industrial psyche injury (cumulative) and barred permanent disability from psyche injury (specific injury). Applicant contended that medical evidence supported cumulative psyche injury and that the WCJ erred in denying compensability of psychiatric permanent disability due to catastrophic consequences. The Appeals Board granted the petition for reconsideration, rescinded the prior Findings and Award, and returned the matter to the trial level for further proceedings, citing the need for further development of the medical record regarding intertwined disability and the application of the catastrophic injury exception.

REYNA MEZA vs. PACPRO MANAGEMENT, Dba COAST SPORTSWEAR, AMERICAN CLAIMS MANAGEMENT for EVEREST NATIONAL INSURANCE COMPANY, CALIFORNIA INSURANCE GUARANTEE ASSOCIATION, By Its Facilitating Agent, INTERCARE INS. SERVICES, for PAULA INSURANCE COMPANY, In Liquidation

Everest National Insurance Company seeks reconsideration of an arbitrator's decision awarding CIGA $\$95,245.36$ in reimbursement for cumulative trauma benefits. Everest argues the arbitrator erred by finding the cumulative trauma extended over the applicant's entire employment, contrary to the Agreed Medical Examiner's (AME) opinion. The Appeals Board granted reconsideration, finding the AME's opinion legally flawed and lacking substantial evidence for the extended cumulative trauma period. The matter is remanded to the arbitrator for further proceedings to develop the medical record and render a new decision.

ROBYN ARIAS vs. STATE OF CALIFORNIA DEPARTMENT OF CORRECTIONS & REHABILITATION

This case involves a correctional officer's cumulative trauma claim. The employer sought reconsideration, arguing the cumulative trauma ended on July 8, 2014, as the applicant allegedly sustained no disability prior to that date. However, the Board denied reconsideration, affirming the WCJ's finding that the applicant experienced disability earlier due to chemotherapy for non-Hodgkins lymphoma. This disability, occurring from February 2007 to February 2008, establishes the injury's cumulative trauma period under Labor Code section 5412.
