MBI means Medicare Beneficiary Identifiers (MBIs)
By now every eligible Medicare recipient must have received his or her new Medicare card. The new Medicare card shows new number that identifies each beneficiary is known as MBIs. Each number is unique and consists of 11 random characters.
CMS removed Social Security Number (SSN)-based Health Insurance Claim Numbers (HICNs) from Medicare cards and are now using Medicare Beneficiary Identifiers (MBIs) for Medicare transactions like billing, eligibility status, and claim status. Until 12/31/19 when the transition period ends, CMS will keep using the HICN with business partners such as:
• The Social Security Administration (SSA)
• The United States Railroad Retirement Board (RRB)
• Health care providers
• Health plans
Every person with Medicare has been assigned an MBI. The MBI is confidential like the SSN and should be protected as Personally Identifiable Information.
Starting January 1, 2020, one MUST submit claims using MBIs (with a few exceptions), no matter what date you performed the service.
What do MBIs look like?
The MBIs are clearly different than the HICN and RRB number.
How many characters will the MBI have? The MBI has 11 characters, like the Health Insurance Claim Number (HICN), which can have up to 11. Will the MBI’s characters have any meaning? Each MBI is randomly generated. This makes MBIs different than HICNs, which are based on the Social Security Numbers (SSNs) of people with Medicare. The MBI’s characters are “non-intelligent” so they don’t have any hidden or special meaning. What kinds of characters will used in the MBI? MBIs are numbers and upper-case letters. We’ll use numbers 0-9 and all letters from A to Z, except for S, L, O, I, B, and Z. This will help the characters be easier to read. If you use lowercase letters, our system will convert them to uppercase letters. How will the MBI look on the new card? The MBI will contain letters and numbers. Here’s an example: 1EG4-TE5-MK73 • The MBI’s 2nd, 5th, 8th, and 9th characters will always be a letter. • Characters 1, 4, 7, 10, and 11 will always be a number. • The 3rd and 6th characters will be a letter or a number. • The dashes aren’t used as part of the MBI. They won’t be entered into computer systems or used in file formats.
• Made up only of numbers and uppercase letters (no special characters); if you use lowercase letters, our system will convert them to uppercase letters.
The MBI doesn’t use the letters S, L, O, I, B, and Z to avoid confusion between some letters and numbers (e.g., between “0” and “O”).
Do the MBI’s characters have any meaning?
Each MBI is unique, randomly generated, and the characters are “non-intelligent,” which means they don’t have any hidden or special meaning.
What do MBIs mean for people with Medicare?
The MBI doesn’t change Medicare benefits. People with Medicare may start using their MBIs right away.
Starting on January 1, 2020 when the transition period is over, we’ll no longer accept HICNs.
People with Medicare who belong to a Medicare Advantage plan or a Medicare drug plan (Part D) should keep using their Medicare Advantage and/or Medicare drug plan cards like they always have when they get health care services or fill a prescription. People with Medicare will also need their MBIs when they change plans or are admitted to the hospital. Source: CMS
