How do I get my Medicare MBI number?

Answered by Douglas Hiatt

To obtain your Medicare MBI (Medicare Beneficiary Identifier) number, you have a few options. The first and easiest way is to ask your patients directly for their Medicare cards. The MBI is a unique identifier that replaced the Social Security Number-based Health Insurance Claim Number (HICN) to protect the privacy and security of Medicare beneficiaries.

If your patients have not received a new Medicare card with their MBI, you can refer them to the Your Medicare Card website. This website provides information on when and how new cards are being issued, as well as what to do if a card has not been received.

As a healthcare provider, you can also use the MBI Lookup Tool in myCGS (my Celerian Group Services), a secure online portal for Medicare providers. However, to access this tool, you must sign up for myCGS and go through the registration process. Once registered, you can use the MBI Lookup Tool to search for a patient’s MBI by entering their HICN or other identifying information.

It’s important to note that the MBI Lookup Tool is only available to Medicare providers and not to the general public. Providers must ensure they are using the tool for legitimate purposes and in compliance with applicable privacy and security regulations.

In summary, to obtain your Medicare MBI number, you can ask your patients for their Medicare cards. If a card has not been received, you can refer them to the website. Additionally, as a Medicare provider, you can use the MBI Lookup Tool in myCGS after signing up for the portal.
