MBI required on HIPAA trans
Description

When are we required to accept the MBI on a HIPAA transaction? We know that MBI replaced HICN but when do we have to accept the MBI? The CMS website is unclear. Their comment seems to indicate that we can continue to require our Unique member id as issued by the health plan: "You don’t need to change your members’ ID numbers unless those ID numbers include whole or parts of their SSNs. We urge you to keep using the unique identifiers that you’ve been using and not to include MBIs on your members’ ID cards" So do we need to accept the MBI on X12 HIPAA transactions?

Response

This RFI is outside of the purview of X12.
