New Medicare Card: Need an MBI?

Thursday, March 14, 2019

All providers (hospitals and other facilities, group practices, labs, etc.) can use their Medicare Administrative Contractor’s (MAC’s) secure portal Medicare Beneficiary Identifier (MBI) look-up tool. Even if your patient is in a Medicare Advantage Plan, you can look up the MBI to bill for things like indirect medical education. If you do not have access to the tool, sign up.

Your patient’s Social Security Number (SSN) is required for the search and may differ from their Health Insurance Claim Number (HICN), which uses the SSN of the primary wage earner. If your Medicare patients do not want to give their SSN, they can log into to get the MBI.

If the look-up tool does not return an MBI, be sure you are using the full last name, including any suffix, such as Jr, Sr, or III.
