An upper extremity impairment rated as 100% corresponds to what percentage of whole person impairment?

An upper extremity impairment rated as 100% corresponds to what percentage of whole person impairment?

• A. 60%
• B. 20%
• C. 50%
• D. 75%

Answer: (A)

In impairment evaluation, the whole person impairment (WPI) is determined from charted conversions rather than being equal to the limb’s own impairment. The AMA Guides provide a standard conversion for the upper extremity, and the maximum impairment of an arm is mapped to 60% WPI. So an upper extremity rated at 100% impairment corresponds to 60% whole person impairment. The other numbers (20%, 50%, 75%) don’t align with this established conversion.
