The claimant was involved in an MVA wherein she suffered, among other things, a mild traumatic brain injury. She had not returned to work following the MVA. The claimant sought a catastrophic designation asserting she met the 55% threshold whole person impairment rating. The insurer commissioned IE reports in which it was found she had a 40% WPI. Adjudicator Susan Sapin concluded that the claimant’s impairments equated to a 51% WPI and was therefore not CAT.
