Common Working File (CWF) Calculation of Next Eligible Date for Preventive Services

To determine when preventive screening services coverage is available for Medicare beneficiaries, CWF will calculate a next eligible preventive services date (date in which the service would be covered by Medicare). The CWF will feed this data to other applications including the beneficiary data extracts for the Next Generation Desktop and the NHIC and WPS provider internet pilots as well as the Medicare Beneficiary Database for the 271 response when requested on the 270. This data will also be available on an HIMR screen, all CWF provider query screens (HUQA, HIQA, HIQH, ELGA, ELGB, ELGH), and the Multi-Carrier System Desktop Tool.
