New Medicare card mailing schedule updated for September 2018

Written by |

New Medicare cards will be showing up in mailboxes before you know it!

In a move to combat medical identity theft, the Centers for Medicare and Medicaid Services is issuing new cards that no longer include Social Security numbers.

You’ve probably heard about this for a few years, but it’s finally happening…

Every Medicare beneficiary is about to receive a new health insurance card

New Medicare cards will gradually be mailed to everyone with Medicare based on geographic location and other factors. Here’s what the new paper cards look like:

Medicare Beneficiary Identifier

The SSN-based Health Insurance Claim Number (HICN) is being replaced with an 11-character Medicare Beneficiary Identifier (MBI), which is made up of numbers and uppercase letters.

Each MBI is randomly generated and the characters don’t have any hidden or special meaning.

Once you receive your new Medicare card with an MBI, you can use it right away and destroy your old card. Your coverage and benefits will stay the same.

When will you receive a new Medicare card?

The cards will be mailed to beneficiaries in waves. You can sign up to receive an email when your card is in the mail at This map from Medicare shows where things stand as of September 2018:
