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

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 ratings, limb impairments are converted to whole person impairment using the AMA Guides conversion. A complete impairment of the upper extremity is assigned 60% of the whole person impairment. So, 100% upper extremity impairment corresponds to 60% whole person impairment. This reflects how losing an arm weighs into overall body function within the standardized rating system. The other options don’t match the established conversion: they would under- or overstate the impact relative to the standard table.
