The Medicare Beneficiary Identifier (MBI) Lookup tool allows providers to use our secure eServices online portal to obtain the new MBI number when patients do not present their Medicare card. If you do not already have access, sign up now for access to eServices to use the tool.
As background, the New Medicare Card Project was established in the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 which mandates the removal of the Social Security Number (SSN)-based Health Insurance Claim Number (HICN) from Medicare cards by April, 2019. CMS began mailing new Medicare cards with the MBI on April 2, 2018.
Beginning in January, 2020, providers may only use MBIs, with limited exceptions.
To submit an inquiry you must do the following:

In the event that your MBI Lookup request does not result in a successful response, eServices will display an error message to assist you. If any required fields are left blank or are not in a proper format, a message will appear advising you which fields to correct.
