Authorities as the decision cited them, with how this panel applied each one.
Labor Code section 5952(d); Lamb v. Workmen's Comp. Appeals Bd. (1974) 11 Cal.3d 274; Garza v. Workmen's Comp. Appeals Bd. (1970) 3 Cal.3d 312; LeVesque v. Workmen's Comp. Appeals Bd. (1970) 1 Cal.3d 627
A finding of cumulative injury must be supported by substantial evidence in light of the entire record.
The WCAB emphasized the need for substantial evidence to support a cumulative injury finding.
From the decision · page 1As with any decision by a WCJ, a decision whether applicant sustained a cumulative injury
must be supported by substantial evidence in light of the entire record. (Lab. Code, § 5952(d); See Lamb v. Workmen's Comp. Appeals Bd. (1974) 11 Cal.3d 274, 281 [39
Cal.Comp.Cases 310]; Garza v. Workmen's Comp. Appeals Bd. (1970) 3 Cal.3d 312, 317 [35
Labor Code section 3208.11
A cumulative industrial injury occurs when repetitive physically traumatic activities cause disability or need for medical treatment.
The WCAB cited this statute to define cumulative industrial injury and the need for medical proof on causation.
From the decision · page 2Labor Code section 3208.11 provides that a cumulative industrial injury occurs whenever
the repetitive physically traumatic activities of an employee's occupation cause any disability or a
need for medical treatment. The question of whether repetitive traumatic activities caused injury
can only be answered with substantial medical evidence. It has long been recognized that medical
proof is required when issues of diagnosis, prognosis, and treatment are beyond the bounds of
ordinary knowledge. (City & County of San Francisco v. Industrial Acc. Com. (Murdock) (1953)
117 Cal.App.2d 455 [18 Cal.Comp.Cases 103]; Bstandig v. Workers' Comp. Appeals Bd. (1977)
68 Cal.App.3d 988 [42 Cal.Comp.Cases 114].)
Labor Code section 4060(c)
Medical evaluations to determine compensability after claim filing must follow the procedure in Labor Code section 4062.2 if the employee is represented by an attorney.
The WCAB noted the requirement for medical evaluations under section 4062.2 when the employee has attorney representation.
From the decision · page 2Labor Code section 4060(c) states, "[i]f a medical evaluation is required to determine
compensability at any time after the filing of the claim form, and the employee is represented by
an attorney, a medical evaluation to determine compensability shall be obtained only by the
procedure provided in Section 4062.2." Section 4060(c) clearly provides that "the section 4062.2
procedure for medical evaluations on compensability may be undertaken 'at any time' after a claim
form has been filed." (Mendoza v. Huntington Hospital (2010) 75 Cal.Comp.Cases 634, 642
(Appeals Bd. en banc).)
