A 100% upper extremity impairment is what percentage of a whole person impairment?

• A. 20%
• B. 50%
• C. 60%
• D. 75%

Answer: (C)

In California SIP work, impairment ratings are expressed as a Whole Person Impairment (WPI) percentage, which comes from converting a limb or body-part impairment using the standard AMA Guides tables. For the upper extremity, a full, 100% impairment of that limb translates to a 60% WPI. So a 100% upper extremity impairment equals 60% of the whole person impairment. The other numbers don’t match the established conversion from upper-extremity impairment to WPI. This conversion is essential because WPI is the measure used for evaluating benefit entitlement and overall impairment.
