This dataset conisists of a list of due dates by which the provider/supplier's revalidation application must reach their MAC (Medicare Administrative Contractor) in order for them to remain in compliance with Medicare's provider enrollment requirements.

The Revalidation Due Date List dataset contains revalidation due dates for Medicare providers who are due to revalidate in the following six months. If a provider's due date does not fall within the ensuing six months, the due date is marked 'TBD'. In addition the dataset also includes subfiles with reassignment information for a given provider as well as due date listings for clinics and group practices and their providers. Note: This full dataset contains more records than most spreadsheet programs can handle, which will result in an incomplete load of data. Use of a database or statistical software is required.
