General information
What is an impairment assessment?
An impairment assessment is undertaken if a worker has a permanent impairment resulting from a work injury. When the work injury has stabilised, the worker's claims manager will discuss referral to an accredited impairment assessor.
Who is an Accredited Impairment Assessor?
Accredited impairment assessors are consultant physicians or surgical specialists that are accredited under the Impairment Assessor Accreditation Scheme established by the Minister for Industrial Relations. Their role is to assess injured workers and prepare assessment reports in accordance with the relevant edition of the Impairment Assessment Guidelines to determine:
- whether the injury has stabilised
- whether the worker's injury has resulted in an impairment
- whether the impairment is permanent
- the degree of whole person impairment resulting from the work injury.
Further information about impairment assessments is detailed in section 22 of the Return to Work Act 2014- external site- external site- external site- external site- external site- external site- external site- external site- external site- external site- external site- external site- external site- external site.
