Cycle 2 of Medicare Part B provider and group enrollments has started (required every 5 years). Unlike Cycle 1, if you miss your revalidation deadline; and a Medicare number is deactivated, you will NOT be able to retroactively bill for services.
Reactivation of your Medicare number will be the date your revalidation was finally received by the Medicare contractor. Centers for Medicare & Medicaid Services (CMS) has a new web tool for you to check for due dates for revalidations. The tool will be updated every month.

Due dates for revalidation are listed six months in advance in this tool. If the due date indicates “TBD” (to be determined), DO NOT submit the revalidation.
Additional information is also posted at the First Coast Service Options Website.
