Medicare Plus Blue Update to Member ID Cards

Posted: 12/09/2025

Medicare Plus Blue migrating members will receive a new ID card. Doctors, pharmacies and other health care providers need the members’ new ID card so they can correctly submit claims.

The format of member ID cards will be revised to include:

  • A new alphanumeric prefix (X3L)
  • A deidentified enrollee ID number(for ~75% of members)
  • A nine-digit group number (previously five-digit group number)
  • The pharmacy group will change from BCBSMAN to BCBSMAN2
