Medicare Beneficiary Identifier (MBI) Look-up Tool: Palmetto GBA's new Medicare Beneficiary Identifier (MBI) tool is now available in eServices for providers to obtain patients' MBI numbers. The MBI Look-up tool will only return an MBI if the new Medicare card has been mailed to avoid potential confusion if the MBI is used before the beneficiary receives their new Medicare card.
