Quick Definitions: "Impairment Rating"

Also sometimes called a "PPD rating," this is the percentage of impairment that the ATP assigns to the specific body part that was injured in a work accident, or to the body as a whole. It is usually assigned towards the end of your treatment. This rating, which must be based upon the American Medical Association's Guides to the Evaluation of Permanent Impairment (5th Edition), is used to calculate your entitlement to PPD benefits.
