LAURA RAMIREZ vs. LOYOLA MARYMOUNT UNIVERSITY, TRAVELERS

This case involved a custodian injured on the job, causing admitted industrial injury to her knee and lumbar spine. The Administrative Law Judge apportioned 50% of the permanent disability to pre-existing arthritis, a decision the applicant contested. The Workers' Compensation Appeals Board denied reconsideration, finding the apportionment supported by medical evidence indicating the industrial injury and pre-existing arthritis jointly necessitated knee replacement surgery. This aligns with precedent requiring apportionment to all causative factors, including underlying pathology.

Claim of Milner v. Country Developers, Inc.

The Special Disability Fund appealed decisions by the Workmen’s Compensation Board which imposed liability on the Fund for a claimant's injuries. The Board found that the employer, Country Developers, continued to employ the claimant, a carpenter, with knowledge of his pre-existing permanent physical impairment, triggering liability under subdivision 8 of section 15 of the Workmen’s Compensation Law. The claimant suffered a fracture of the nose and a hip dislocation in 1964, having a history of three ruptured disc surgeries and other conditions. The appeal centered on whether the employer had sufficient knowledge of the claimant’s permanent condition. Testimony from the employer’s foreman, Mr. Pahlck, indicated awareness of the claimant's back issues, including wearing a back brace and being favored by co-workers. The court affirmed the Board’s decision, reiterating that employer knowledge is a question of fact for the Board, and its findings, if supported by substantial evidence, will not be disturbed.

LOURDES OCAMPO vs. SWEETWATER UNION HIGH SCHOOL DISTRICT

The Workers' Compensation Appeals Board granted reconsideration of the initial decision, finding the orthopedic QME's opinions did not constitute substantial evidence. Applicant contended the QME's opinions were inconsistent with medical literature regarding the acceleration of pre-existing conditions. The Board agreed that the QME seemed to conflate causing arthritis with aggravating a pre-existing condition. Therefore, the Board rescinded the original findings and returned the case for further development of the record, specifically regarding the extent of applicant's walking and a clearer medical opinion on causation.

LOLA ROBINSON vs. SHELTER NETWORK, SUBSEQUENT INJURIES FUND of the STATE OF CALIFORNIA

The Workers' Compensation Appeals Board affirmed a prior award for applicant Lola Robinson against the Subsequent Injuries Benefits Trust Fund (SIBTF). The award compensated her for a combined permanent disability of 78%, stemming from a subsequent industrial injury to her upper extremity and pre-existing conditions of hepatitis C and a hysterectomy. The Board found that medical evidence established pre-existing whole person impairments from these conditions, meeting the "labor disabling" threshold for SIBTF benefits. The Board held that the physician's ratings under the AMA Guides constituted prima facie evidence of pre-existing impairment, which the SIBTF failed to rebut.

Claim of Kakuriev v. Home Service Systems, LLC

The Special Disability Fund appealed a Workers' Compensation Board decision that granted reimbursement to an employer and its carrier for a claimant's pre-existing knee injuries. The claimant, a home health aide, suffered work-related injuries to her knees, back, and neck, leading to a determination of mild to moderate permanent partial disability. The employer sought reimbursement under Workers’ Compensation Law § 15 (8), asserting pre-existing knee conditions. However, the appellate court reversed the Board's determination, finding that the employer failed to present evidence that the claimant's pre-existing impairment hindered her job potential, which is a requirement for reimbursement from the Fund. The matter was remitted to the Workers’ Compensation Board for further proceedings.

Claim of Peziol v. Vaw of America

The claimant, a millhand with a pre-existing severe arthritic spinal condition and a 20-pound lifting restriction since October 1992, sustained a back injury in June 1994 while lifting aluminum pipes, rendering him totally disabled. The Workers' Compensation Board ruled that the claimant's disability was causally related to a work-related accident and awarded benefits. The employer contested this decision, arguing for apportionment due to the pre-existing condition. However, the court found substantial evidence supporting the Board's decision, noting that the claimant was able to perform his duties despite the pre-existing condition until the work-related injury. Consequently, the court affirmed the Board's decision, concluding that apportionment did not apply.

Claim of Terwilliger v. Green Fuel Economizer, Inc.

The claimant appealed a Workers' Compensation Board decision, challenging both the apportionment of his award between an industrial accident and a pre-existing condition, and the board's finding of moderate disability. The court emphasized that full compensability hinges on whether the industrial accident activated a previously dormant and non-disabling pre-existing condition. Despite the claimant's attending physician testifying that his pre-existing condition was asymptomatic prior to the accident, the record contained evidence of prior low back problems. The court reiterated that resolving conflicting medical evidence, concerning both apportionment and the degree of disability, falls exclusively within the Board's purview. Since the Board's decision was supported by substantial evidence, the appellate court affirmed it.

Claim of Garcia v. Brassiere Restaurant

A claimant with a known pre-existing brain condition suffered a lacerated scalp at work. Subsequently, the claimant developed cerebellar degeneration and became permanently and totally disabled. An impartial neurologist determined that while the claimant experienced minor head and neck pain causally related to the accident, the severe disability stemmed from a progressive degenerative disease and a posttraumatic seizure disorder, neither of which were found to be causally related to the work accident or exacerbated by the pre-existing condition. The Workers’ Compensation Board relieved the Special Fund from liability, concluding that the pre-existing impairment did not materially and substantially increase the permanent disability beyond what the subsequent injury alone would have caused. The appellate court affirmed the Board's decision, citing substantial evidence.

Claim of Rushnek v. Ford Motor Co.

The Workers' Compensation Board ruled that Ford Motor Company was entirely responsible for a claimant's hearing loss, which began with a 13% pre-employment loss and progressed to 23.2% by retirement. Ford appealed this decision, challenging its liability for the pre-existing portion of the hearing loss, especially considering the timing of the relevant Workers' Compensation Law provisions. The court clarified that the date of disablement, in this instance, was August 1974, thus making Workers' Compensation Law § 49-ee applicable. It determined that while the last employer is generally liable for total hearing loss, an exception exists for pre-existing, occupationally caused hearing loss, allowing for reimbursement. The court reversed the Board's decision and remitted the case, instructing further proceedings to ascertain if the claimant's initial hearing loss was work-related, which would then allow Ford to seek reimbursement from prior employers.

ERNEST J. WILLIAMS vs. PINKERTON SECURITY, ESIS

This case involves an applicant who sustained an industrial injury to his right knee. The defendant sought reconsideration of the original award, arguing the judge erred in denying credit for temporary disability overpayments and in failing to apportion permanent disability to pre-existing arthritis. The Appeals Board granted reconsideration, rescinded the original award, and returned the matter for further proceedings. The Board found that apportionment to prior arthritis, even if it necessitated knee replacement surgery, is required under current law and that the Agreed Medical Evaluator's opinion on apportionment was sufficient.
