What is an mbi number?

An MBI (Medicare Beneficiary Identifier) number is a unique, 11-character identifier assigned to individuals enrolled in Medicare. Introduced as a replacement for the previous Health Insurance Claim Number (HICN), the MBI enhances security by removing Social Security numbers from Medicare cards. This change helps protect beneficiaries from identity theft and fraud.

Why Was the MBI Introduced?

The transition to MBI numbers was a crucial step in safeguarding Medicare recipients’ personal information. Unlike the HICN, which was based on Social Security numbers, the MBI is randomly generated and does not contain any personal details. This makes it much harder for fraudsters to misuse Medicare information.

Understanding the MBI Format

The MBI consists of 11 characters, a mix of numbers and uppercase letters. To avoid confusion, certain letters—such as S, L, O, I, B, and Z—are not used. While the structure is unique to each individual, it follows a specific format that ensures security and usability across Medicare services.

How to Use Your MBI Number

• Medical Appointments: Always carry your Medicare card with your MBI to present during visits to doctors, hospitals, and other healthcare providers.

• Billing and Claims: Healthcare providers use the MBI to verify eligibility and process claims efficiently.

• Protect Your MBI: Treat your MBI like any other sensitive personal information. Do not share it unless necessary, and be cautious of scams requesting your Medicare details.

What to Do If You Lose Your MBI?

If you misplace your Medicare card, you can retrieve your MBI by:

• Logging into your Medicare account online.

• Contacting Medicare services for assistance.

• Checking previous medical bills or statements where your MBI might be listed.
