The purpose of this exchange is to identify any Medicare beneficiary who may be eligible for Medicare cost sharing under the Medicaid program, notify these potential Medicare buy-in eligible beneficiaries about the Medicare cost-sharing programs, and inform the states of potential buy-in eligible beneficiaries. Medicare Savings Programs are state-administered Medicaid programs which subsidize Medicare beneficiary costs. These programs usually follow SSI methods for counting income and resources but have higher limits. The income tests are based on a percentage of the Federal poverty guidelines and vary by program. Each year, two separate files will be created. The first file is scheduled for April and includes the QMB/SLMB/QI file. The second file is scheduled for November and includes the QDWI file.
