The Medicare Beneficiary Identifier (MBI – which replaces the patient’s social security number) uses numbers 0-9 and all uppercase letters except for S, L, O, I, B, and Z. These letters have been excluded to avoid confusion when differentiating some letters and numbers (e.g., between ‘0’ and ‘O’).

You should start using the new MBI should as soon as your patients get their new card. January 1, 2020 is the drop dead date. After which the patient’s social security number will no longer be accepted on the claim form regardless of the date of service.

New Medicare Cards May Have QR Codes
New Medicare cards may have a square code, also referred to as a QR (Quick Response) code (a type of machine-readable code). The QR codes on Medicare cards allow the contractor who prints the cards to ensure the right card goes to the right person with Medicare or Railroad Retirement Board (RRB) benefits. Providers cannot use it for any other purpose. The RRB issued cards may have a QR code on the front of the card while all other Medicare patients may get a new card with a QR code on the back of the cards. These are legitimate (official) Medicare cards.
