An impairment benefit is a lump sum payment which compensates a claimant for their injuries. To receive an impairment payment, impairment must exceed 10%.
Impairment is expressed as a percentage of the whole body/person. The percentages are calculated using the Guides to the Evaluation of Permanent Impairment – 4th Edition.
The final impairment percentage is calculated by TAC. The calculation follows examinations by medical specialists. These specialists must be accredited to the use of the impairment guides.
Impairment is different from disability. The Guides do not assess disability, only impairment.
The Guides are said to be scientific. However, different outcomes are common. Similarly qualified medical specialists can produce different impairment outcomes. Therefore you should obtain expert legal advice concerning the impairment issue.
