CMS has reported that more then two thirds of Medicare claims now use the MBI instead of the HIC number. All claims must use the MBI by the end of 2019. Medicare has published two handy references to help:
Sign into https://www.mymedicare.gov/ to see if their card has been mailed. If so, they can print an official card. If they do not already have an account, they need to create one.
Call 1-800-MEDICARE (1-800-633-4227). There might be something that needs to be corrected, such as updating their mailing address.
Mailings to Idaho, Montana, and Washington will not begin till August at the earliest, and probably considerably later. CMS is committed to mailing new cards to everyone with Medicare by April 2019. Until December 31, 2019 health care providers and suppliers can use either the former SSN-based HIC Number, OR the alpha-numeric MBI (Medicare Beneficiary Identifier) on the new cards, for all Medicare transactions.
The CMS MLN Matters document on New Medicare Beneficiary Identifier (MBI): Get It, Use It has recently been revised, but the only change is the addition of the information (on page 2) that the MBI does not use the letters S, L, O, I, B, or Z in order to avoid confusion with similarly-shaped numbers.
The CMS New Medicare Card (NMC) web page at https://www.medicare.gov/newcard/ keeps an ongoing tally of NMC mailings. It shows that mailings are now underway for California, Oregon, and Alaska, but have not yet started for other Network 16 states. The page also includes a sample of the new card, important information about what a patient should do when they receive one in the mail, and important tips on avoiding Medicare scams.
CMS has published information about helping patients avoid fraud and scams, which may be particularly important with the release of the New Medicare Cards.
Medicare will never call beneficiaries uninvited and ask for personal or private information to get their new Medicare Number and card. Scam artists may try to get personal information (like their current Medicare Number) by contacting them about their new card. If your Medicare patient is asked for their information, for money, or someone threatens to cancel their health benefits if they don’t share their personal information, have them call 1-800-MEDICARE (1-800-633-4227).
