MONTHLY REPORT
Appeals Board reviews apportionment
under the new law
This is an En Banc
decision of the
Appeals Board.
T
he applicant had an
industrial injury to her
left knee. The applicant
alleged as a compensable
consequence of that a right knee
problem. The applicant had
surgery to the left knee.
The defense doctor
apportioned the applicant's
disability on the fact that the
applicant had significant
degenerative arthritis in both
knees. This was based on
reasonable medical probability.
The Workers' Compensation
Judge (WCJ) agreed with the
defense doctor and apportioned.
The applicant filed a petition for
reconsideration.
The Workers' Compensation
Appeals Board ( WCAB) issued a
n En Banc decision. They
reviewed SB 899.
They indicated that Labor
Code section 4663 (a)'s
apportionment of permanent
disability is based on causation of
permanent disability , not
causation of injury.
Section 4663 (c) indicates
what standards the WCAB must
use for this determination and
how to determine what
percentage of permanent
disability was caused by other
factors.
The applicant has the burden
of determining the percentage of
disability caused by the injury
while the defendant has the
burden of what disability was
caused by other factors.
Disability can be apportioned
to pathology, asymptomatic prior
conditions, and a retroactive
prophylactic work preclusion,
even though this had been
disallowed in the past under prior
case law. There must be
substantial medical evidence of
the apportionment. The doctor
must state the reasons for the
opinions and that it is based on
reasonable medical probability.
