The claimant sought entitlement to various medical benefits; the insurer sought repayment of IRBs due to overpayment of the weekly quantum. Adjudicator Treksler held that the claimant failed to provide evidence that the claimed physical therapy and assessments were reasonable and necessary. She ordered the claimant to repay the overpayment in IRBs, stating that the insured had complied with all of the requirements of section 52 and the claimant had not shown that any exception to repayment applied.
