Section 4 – MBI Lookup

Providers must use the patient’s Medicare Beneficiary ID (MBI) for all transactions. Per CMS MBI education external link, there are three ways to obtain MBIs. This MBI Lookup tool is one of those options. The MBI is confidential and should be protected as Personally Identifiable Information (PII) and used only for Medicare related business. CMS requires specific data elements, including the beneficiary’s social security number to obtain the MBI.
To use the MBI Lookup, take the following steps:
1. Select MBI Lookup from the top menu.
