What is Impairment Rating?
A percentage assigned by a physician that measures the degree of permanent physical impairment resulting from an injury, based on standardized medical guidelines.
Understanding Impairment Rating
Impairment ratings are typically assigned using the American Medical Association's Guides to the Evaluation of Permanent Impairment. They are expressed as a percentage of whole-body impairment. These ratings are critical in workers' compensation cases for determining benefits and in personal injury cases for quantifying the severity of permanent injuries. A higher rating generally corresponds to greater compensation.
Examples
- 1Doctor assigning 15% whole-body impairment rating for herniated disc
- 2Workers' compensation benefits calculated based on 25% impairment
- 3Disagreement between treating doctor and defense doctor on rating percentage
