Apportionment:
What does it Mean? Stephen L. Kline, Esq.
ARMSTRONG LAW FIRM
stephenk@arm-law.com On
the First Anniversary of SB 899, April 19, 2005, the Workers Compensation
Appeals Board, en banc, issued the Escobedo v Marshalls, et al.
70 Cal Comp Cases (2005) decision with instructions as to what
apportionment means under Labor Code sections 4663 and 4664. They
set out five specific holdings.
The first one … Causation of the injury is a different
analysis than the causation of the permanent disability. “T
he percentage to which an applicant’s injury is
causally related to his or her employment is not necessarily the
same as the percentage to which an applicant’s permanent
disability is causally related to his or her injury.” With
the exception of psychiatric injuries, the percentage of causation
of an injury can be as low as 1%, if one can establish the principles
of AOE/COE. The applicant obtains temporary disability, medical
treatment and after 1/1/04, a supplemental job displacement voucher.
The second holding looked directly to the unambiguous words of
the Labor Code section 4663(c):
“ In order for a physician’s report to be considered
complete on the issue of permanent disability, it must include
an apportionment determination. A physician shall make an apportionment
determination by finding what approximate percentage of the permanent
disability was caused by the direct result of injury arising out
of and occurring in the course of employment and what approximate
percentage of the permanent disability was caused by other factors
both before and subsequent to the industrial injury, including
prior industrial injuries.”
When a permanent disability amount is determined for an injured
worker, then the analysis turns to what caused that disability.
There are two percentages which equal 100%. There is the approximate
percentage that is DIRECT RESULT of the injury that arose out of
and occurred at the employment. The other percentage is “OTHER
FACTORS”.
The simplicity of this section has befuddled Applicant’s
attorneys for a year.
The third holding involves burdens of proof. “The applicant
has the burden of establishing the percentage of permanent disability
directly caused by the industrial injury.” “The defendant
has the burden of establishing the percentage of disability caused
by other factors.”
Burdens of proof are important because Labor Code section 3202.5
sets out that when it comes to burdens of proof; all parties are
equal before the law. Thus if the Applicant fails to meet its burden
to prove, with a preponderance of the evidence, the percentage
of the permanent disability which occurs as a direct result of
the injury AOE / COE, then he/she cannot get a boost from the Labor
Code section 3202 that the workers compensation law should be interpreted
so as to favor giving the injured worker the benefits.
The fourth holding is the most controversial and caused tremors
throughout the applicant attorney world …. “Apportionment
of permanent disability caused by ‘other factors both before
and subsequent to the industrial injury, including prior industrial
injuries,’ may include not only disability that could have
been apportioned prior to SB 899, but it also may include disability
that formerly could not have been apportioned (e.g., pathology,
asymptomatic prior conditions, and retroactive prophylactic work
preclusions), provided there is substantial medical evidence establishing
that these other factors have caused permanent disability.”
This is HUGE! Diabetes, obesity, osteoarthritis, congenital defects,
prior physical impairments and so many other factors that can & should
be considered by the reporting physician to determine the causation
of the injured worker’s disability.
The final holding recapitulates prior case law as to what constitutes “substantial
evidence” and thus what reports are admissible before the
Board.
Our job as defense attorneys and claims adjusters is to make sure
that all medical reporters understand what apportionment means.
The Legislature and now the WCAB have given us at least one tool
to bring the workers compensation system under control.
The heart of the WCAB’s decision rests with the consistency
between , “the statement in section 4663(a) that ‘[a]pportionment
of permanent disability shall be based on causation’ and with
the statement in section 4664(a) that ‘ [t]he employer shall
only be liable for the percentage of permanent disability directly
caused by the injury.’”
