You’ve got a little more time to recertify for DDE access if National Government Ser-vices is your MAC. “Due to the number of users who did not respond, National Government Servi-ces has extended the deadline to allow more time for users to act before their logon IDs are terminated,” the MAC says in a June 5 message to providers. You’ve got until June 16 to recertify, or NGS will cut off your DDE access. To recertify your access, go to http://apps.ngsmedicare.com/applications/ recert_2014cont.aspx.
