Authorities as the decision cited them, with how this panel applied each one.
Lab. Code, §§ 3208.1, 3208.2
All questions of fact and law must be separately determined with respect to each specific or cumulative injury.
WCAB amended findings to separately determine injuries and dismiss duplicative claim.
From the decision · page 3Bank of America (2010) 75 Cal.Comp.Cases 613 (Appeals Board en banc) [delineating the roles
of WCJs and physicians in the adjudication process].) Most importantly, statutory workers'
compensation law provides that an industrial injury may be either specific or cumulative, and that
all questions of fact and law must be separately determined with respect to each such injury. (Lab.
Code, § 3208.1, 3208.2.) The WCJ's unquestioning acceptance of Dr. Garland's medical opinion
that applicant's specific orthopedic injuries "melded into one cumulative trauma claim" was error,
because the finding of a single cumulative trauma to supplant the other stipulated, specific injuries
violates sections 3208.1 and 3208.2.
Kopping v. Workers' Comp. Appeals Bd. (2006) 142 Cal.App.4th 1099, 1114 [71 Cal.Comp.Cases 1229]
Defendant has the burden of proving apportionment.
WCAB found defendant did not meet burden to prove apportionment to obesity or diabetes.
From the decision · page 5As for apportionment, two issues are relevant here, i.e., whether there should be
apportionment between the permanent disabilities resulting from applicant's various orthopedic
injuries, and whether there should be apportionment of permanent disability based on applicant's
obesity and diabetes. On both questions, it is well-settled that defendant has the burden of proving
apportionment. (Kopping v. Workers' Comp. Appeals Bd. (2006) 142 Cal.App.4th 1099, 1114 [71
Cal.Comp.Cases 1229].)
Benson v. Workers' Comp. Appeals Bd. (2009) 170 Cal.App.4th 1535 [74 Cal.Comp.Cases 113]
Multiple injuries ordinarily require separate permanent disability awards unless the evaluating physician cannot parcel out the approximate percentages to which each injury contributed.
WCAB found combined award justified because physician could not parcel out percentages.
From the decision · page 5In reference to apportionment between injuries, in Benson v. Workers' Comp. Appeals Bd.
(2009) 170 Cal.App.4th 1535 [74 Cal.Comp.Cases 113] the Court of Appeal concluded that
pursuant to Senate Bill 899 enacted in 2004, the law of apportionment mandates that multiple
injuries ordinarily require separate permanent disability awards. However, the Court also stated
that "there may be limited circumstances...when the evaluating physician cannot parcel out, with
reasonable medical probability, the approximate percentages to which each distinct industrial
injury causally contributed to the employee's overall permanent disability. In such limited
circumstances, when the employer has failed to meet its burden of proof, a combined award of
permanent disability may still be justified." (170 Cal.App.4th at 1560.)
