Best Available Evidence (BAE)
The Centers for Medicare and Medicaid Services (CMS) specify the requirements of a Part D sponsor 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.
