How Do I Update The Medicare MBI (Medicare Beneficiary ID) Format?

The law requires that CMS remove the Social Security Numbers (SSNs) from all Medicare cards by April 2019. A new unique Medicare number will replace the current Health Insurance Claim Numbers on the new Medicare cards.

CMS will begin mailing the new cards to Medicare beneficiaries in April 2018 to meet the April 2019 statutory deadline for replacing all cards. Patients that are new to the Medicare program starting in April 2018 and later will only have one card with the new Medicare number.

You can enter this new number/format in Careficient. The new format will be 11 characters long and consists of number and alpha fields (excluding B, I, L, O, S, Z). Number values will be in positions 1,3*, 4, 6, 7, 10, 11. Alpha characters will be in positions 2, 3, 5, 6*, 8, 9. (*Note that positions 3 and 6 can be either alpha or numeric).

Here’s an example of what the Medicare and The RRB Medicare cards look like:

You can enter this new MBI number using the following access.
