An impairment rating is a percentage intended to represent the degree of an individual's impairment, which is a deviation away from one's normal health status and functionality.[1] Impairment is distinct from disability. An individual's impairment rating is based on the restrictive impact of an impairment, whereas disability is broadly the consequences one's impairment.[2] Impairment ratings given to an individual by different medical examiners are sometimes problematically inconsistent with each other.[3]
