Understanding Whole Person Impairment Ratings in California Workers’ Comp
When a workplace injury leaves lasting limitations, California uses a Whole Person Impairment (WPI) rating to measure the extent of permanent damage. This rating determines how much compensation you’ll receive for permanent disability.
A Qualified Medical Evaluator (QME) or treating doctor assigns your WPI percentage after your condition stabilizes. The rating reflects how your injury impacts your ability to work and perform daily activities. For example, a 20 % WPI means you’ve lost one-fifth of your overall physical capacity.
Your WPI is then adjusted based on age, occupation, and injury type using California’s Permanent Disability Rating Schedule (PDRS). These numbers directly influence the amount and duration of your benefits.
Because medical and legal calculations can be complex, having an experienced attorney review your WPI rating is vital. Even small changes in your percentage can significantly affect your payout.
