What is the age adjustment table in PDRS?
A chart that increases PD for older workers and slightly decreases for younger workers.
Mnemonic for age adjustment
“AGE ↑ PD.”
Why does older age increase PD rating?
Older workers have less ability to retrain or adapt, so disability has greater vocational impact.
What is the FEC (Future Earning Capacity) rank?
Each body part is assigned a rank (1–8) to reflect average earning loss for that injury type.
How is DFEC factor derived?
DFEC is a statutory multiplier linked to FEC rank to adjust WPI to standard PD.
Mnemonic for DFEC
“FEC drives Dollars.”
Can DFEC be rebutted?
Yes, but only with strong vocational/economic evidence that actual earning loss differs from the schedule.
Who can rebut DFEC?
Vocational experts with labor market data; not the QME.
What is the apportionment step in rating?
After final PD % is calculated, non-industrial % is subtracted to find the industrial PD %.
Mnemonic for sequence
“WPI → PD → Apportion.”
Why must QME describe activities of daily living (ADLs)?
AMA Guides impairment is based on impact on ADLs; required for valid WPI rating.
List core ADLs in AMA Guides.
Self-care, communication, physical activity, sensory function, hand activities, sleep, travel.
Mnemonic for ADLs
“SCaPSSHT” — Self-care, Communication, Physical, Sensory, Sleep, Hand, Travel.
What is add-on for complex regional pain syndrome (CRPS)?
CRPS is rated per AMA Guides neuro/skin sections; can increase WPI significantly if criteria met.
How does QME document CRPS?
Must use Budapest/AMA criteria and explain functional loss.
What is upper extremity impairment conversion?
Convert hand/finger/arm % to WPI using AMA Guides tables before applying PD adjustments.
Mnemonic for extremity conversion
“Extremity → WPI → PD.”
Why is laterality important in ratings?
Dominant hand/arm injuries typically result in higher WPI/PD than non-dominant.
Can QME assign pain add-ons to psych claims?
No — pain add-on applies to physical WPI, psych ratings use GAF instead.
What is GAF scale range?
0–100; lower scores = greater impairment; used to convert psych impairment to WPI.
Mnemonic for psych WPI
“GAF Low → PD High.”
What is sexual dysfunction impairment rating rule?
Only compensable if direct injury to reproductive organs or documented psychological impairment; must follow AMA criteria.
What is sleep disorder impairment rating rule?
Sleep dysfunction is rated only if caused by work injury and documented per AMA Guides.
Why are precise anatomic terms needed in WPI?
Vague language prevents correct conversion; body part must match PDRS codes.
