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:
When you get your new Medicare card, destroy your old red-white-and-blue Medicare card, but do not destroy your Social Security card, Medicare Advantage plan card, or drug plan cards. If you belong to a Medicare Advantage plan or a Medicare drug plan (Part D), continue to use these cards when you get health care services or fill a prescription. Dispose of your old Medicare card carefully, as it contains Personally Identifiable Information (PII) that can be used for identity theft. Your dialysis facility will probably have a shredder if you don’t. New Medicare Cards, and your Medicare Beneficiary Identifier on it, are also confidential PII that should be closely guarded.
New Medicare cards have been mailed to all Network 16 and 18 patients. If you haven’t received yours, call 1-800-MEDICARE. Call center representatives can check the status and help you get your new card. Meanwhile, use your current Medicare card to get health care services. While your old card will be good through the end of 2019, you want to get and use your new card as soon as you can.
CMS has begun mailing New Medicare Cards to beneficiaries in Washington, Idaho, and Montana. Mailings are already complete to California, Oregon, and Alaska. For more information see:
CMS has announced that they will hold a 13 September 2018 Open Door Forum on the New Medicare Card. For forthcoming details keep an eye on https://www.cms.gov/Outreach-and-Education/Outreach/OpenDoorForums/ODF_NewMedicareCard.html.
New Medicare Card (NMC) mailings to Alaska, California, and Oregon have been completed. Anyone in those states who did not get a new card, should print a Still Waiting for Your New Card? handout from:
And then either:
- 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.
