CMS sent out an update on the new Medicare cards that were sent out from April 2018 to April 2019. Medicare beneficiaries can request a new MBI if it is compromised thru CMS. If a provider receives an error code of AAA 72 which is “invalid member ID”, your patients MBI may have been changed.
Reminders About Using the Old or New MBIs

- Dates of service before the MBI change date – use old or new MBIs
- Span-date claims with a “From Date” before the MBI change date – use old or new MBIs
