Medicare Beneficiary Identifier (MBI) Look Up Tool
This tool is an option for providers/suppliers to use if they are not able to obtain the MBI number from the patient. The new cards are being mailed in phases following a geographic location strategy.
Inquiry
- Choose TIN/SSN, NPI, PTAN and Program under Provider/Supplier Details
- Enter First Name, Last Name, Date of Birth (DOB) and the patient's Social Security Number (Note: The patients SSN may be different than their HICN. Example: A wife receiving Medicare benefits under their spouse.)
- Enter the "I am not a robot" text (Only needed once for every 5 transactions)
Response
The MBI number will display under the MBI Lookup Details along with the beneficiary information entered for the inquiry.
- If the patient information is not accurate, a message indicating the MBI details could not be located will be displayed.
