At this time, the quickest way to see if a revalidation letter was mailed to you is to check the 'Downloads' on the CMS Revalidation page. You will find mailing lists beginning with September 2011 when the first letters were sent. Information is now available for Medicare Part A/B revalidation letters mailed in April and May. Updated listings are also available for A/B revalidation letters mailed in February/March and for revalidation letters mailed by the National Supplier Clearinghouse (NSC). When information is updated, the link will be revised to show the date the file was updated.
