The Applicant sought a determination that he suffered a catastrophic impairment following a motor vehicle accident.
In a previous decision, the arbitrator found the Applicant's Whole Person Impairment (WPI) was 50%, falling short of the 55% threshold.
On appeal, the Director's Delegate remitted the matter back to arbitration to determine the impairment rating under Chapter 4, Table 3 of the AMA Guides and to assign a rating for medication use.
Upon reassessment, the arbitrator assigned a 15% WPI for the nervous system impairment (after applying a 2% discount for double counting) and a 2% WPI for medication use.
Combining these with the previously confirmed ratings resulted in a 54% WPI, which rounds to 55%.
Consequently, the arbitrator concluded the Applicant sustained a catastrophic impairment.
