Trading Partner ID Recertification
All active trading partners are required to recertify their access annually. CMS requires any changes in demographic, contact information or access for a trading partner ID (TP ID) are communicated to the A/B MAC within 30 days of the change.
The trading partner Recertification form will need to be completed for each active TP ID currently on file with NGS EDI.
Additional information will be distributed as we get closer to launching this initiative.
