The ACC User Handbook to the AMA "Guide to the Evaluation of Permanent Impairment"

Defines levels of impairment for different physical and mental conditions. Used by ACC’s independence allowance and lump sum assessors.

It is proposed that the Injury Prevention, Rehabilitation, and Compensation (Lump Sum and Independence Allowance) Regulations 2002 be amended to replace the current assessment tool for determining the level of permanent impairment, from the Fourth Edition of the American Medical Association Guidelines to the Evaluation of Permanent Impairment (AMA4) and the ACC User Handbook to AMA4 to the Sixth Edition of the Guidelines (AMA6) and the ACC User Handbook to AMA6.
