The insurer filed a request for reconsideration of a LAT hearing decision, in which the adjudicator found that the claimant was entitled to attendant care benefits at a reduced rate and medical expenses. The insurer submitted that the adjudicator erred in making the inference that because the claimant met the threshold for catastrophic impairment, she continued to meet the test for attendant care benefits. The insurer further argued that the adjudicator failed to apply the proper “but for” test for causation. Vice Chair Maedel found that the adjudicator applied the “but for” test in relation to the attendant care benefits analysis, and had not made any errors in fact or law that would have otherwise led to a different decision on the attendant care issue. Vice Chair Maedel found that the adjudicator did make an error in fact and law when she relied on the insurer’s previous approval of travel expenses to find that the current therapy services in dispute were reasonable and necessary and caused by the accident. Previous approval of a benefit was found to be irrelevant and cannot determine causation. Each treatment plan should be evaluated on whether the treatment can be causally linked to the accident and whether the treatments is reasonable and necessary. Vice Chair Maedel found that s. 46(5) does not entitle a claimant to automatic payment of incurred benefits following a catastrophic impairment designation. A claimant must still demonstrate the treatment is causally related to the accident and is reasonable and necessary. In addition, Vice Chair Maedel found that a catastrophically impaired claimant is not entitled to medical benefits that were incurred prior to submission of an OCF-18, even when an insurer has repeatedly denied medical benefits because the non-CAT limit had been reached. The request for reconsideration was granted in part.
