What is best available evidence?
Federal regulations specify the requirements of Part D sponsors in the administration of the low-income subsidy program, including the reduction of cost sharing for subsidy-eligible individuals. In certain cases, CMS systems do not reflect a beneficiary's correct low-income subsidy (LIS) status at a particular point in time. As a result, the most up-to-date and accurate subsidy information has not been communicated to the Part D plan. To address these situations, CMS created the best available evidence (BAE) policy. This policy requires sponsors to establish the appropriate cost-sharing for low-income beneficiaries when presented with evidence that the beneficiary's information is not accurate.
