What does “substantial cause” mean in psych claims?
Workplace events must be at least 51% responsible for the psychiatric condition compared to all other factors combined.
What percentage applies if caused by a violent act?
A lower bar — work must be ≥35% the cause if the psychiatric injury stems from a violent act.
Mnemonic for cause thresholds
“51 for normal, 35 for harm.”
What is a “good faith personnel action” (GFPA)?
A lawful, non-discriminatory, and non-retaliatory employer action (e.g., transfer, discipline, evaluation) that can bar psych claims if it’s the predominant cause.
GFPA as defense?
If the psychiatric injury was caused mainly (>51%) by GFPA, the claim is usually non-compensable.
Mnemonic for GFPA
“Good Faith = Claim Fade.”
What is the 6-month employment rule for psych claims?
Worker must generally have 6+ months employment to file a psych claim.
Exception to 6-month rule?
If the injury results from a sudden and extraordinary event, the six-month requirement does not apply.
How is “sudden and extraordinary” defined?
An unexpected, uncommon, and unusual event (e.g., workplace violence, explosion, sudden traumatic accident).
What is a “compensable consequence” psych injury?
A psychiatric disorder that develops secondary to an accepted physical work injury.
Burden of proof for compensable consequence?
Easier — work physical injury already accepted; must show psych condition flows from that injury.
What are typical triggers for compensable consequence psych injuries?
Chronic pain, disability, loss of function, financial stress, stigma, or difficult recovery.
Why is documentation crucial for psych causation?
History of work events, timelines, and stressors must be well documented to establish AOE/COE.
What are common non-industrial contributors to psych injury?
Personal trauma, family conflict, substance abuse, financial hardship, pre-existing disorders.
Mnemonic for non-industrial contributors
“LIFE” — Life stressors Impact Factoring Evidence.
How should QME handle mixed causation?
Discuss each factor (work vs personal), weigh relative contribution, and state if work ≥51% (or ≥35% violent).
Can QME apportion psychiatric impairment?
Yes — apportion between industrial and non-industrial causes of permanent impairment.
How are psych permanent disability ratings done?
Using GAF (Global Assessment of Functioning) → convert to WPI → then PD under CA schedule.
Mnemonic for psych PD
“GAF → WPI → PD.”
Why is GAF controversial?
It’s subjective and no longer in DSM-5, but still required under CA WC for PD conversion.
What are typical medical records to review?
Personnel records, prior mental health records, injury reports, witness statements, performance reviews.
Importance of temporal relationship?
Onset or worsening of psych symptoms shortly after work stressor strongly supports causation.
How do layoffs/discipline impact claims?
Often central to GFPA defense; must assess if action was lawful, non-discriminatory, and good faith.
What is IME/QME’s key report duty?
Provide clear causation analysis, apportionment, GAF/WPI rating, treatment recommendations, and response to legal standards.
