9/11 New Medicare Card Forum

CMS will hold a September 11, 2019 Open Door Forum on the New Medicare Cards and MBIs (Medicare Beneficiary Identifiers), which become mandatory on January 1, 2020.  For details on the Forum see https://www.cms.gov/Outreach-and-Education/Outreach/OpenDoorForums/Downloads/09112019NewMedicareCardODFAgenda.pdf.  HIC numbers will no longer be valid after December 31, 2019.  If you do not have an MBI for any of your patients, or you have other questions, see the CMS MLN Matters booklet on New Medicare Beneficiary Identifier (MBI): Get It, Use It, at https://www.cms.gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNMattersArticles/downloads/SE18006.pdf.

12/31 Old HICNs Valid for Only Six More Months

There are only six months to go on the transition to the New Medicare Card.  To help prevent identity theft, the New Card removes a patient’s Social Security Number from their Card and replaces it with a new, randomly-assigned “Medicare Beneficiary Identifier” or MBI.  MBIs must be protected as confidential PII.  All patients should have received their new card by now, barring mailing address problems.  After December 31, 2019 billing with the old “Health Insurance Claim Number” or HICN will be disallowed.  If your facility has patients that don’t have a New Card, refer to https://www.cms.gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNMattersArticles/Downloads/SE18006.pdf for instructions.  Railroad Retirement Board Medicare cards are going through a parallel transition.

MBI News

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:

NMC Mailings to WA, ID, MT

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:

New Medicare Card News

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.

New Medicare Card News

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.

For providers, CMS has also published information on when a Medicare Beneficiary Identifier (MBI, which replaces the HICN on the card) can change, and what to do when it does.  Find a summary at https://www.cms.gov/Outreach-and-Education/Outreach/FFSProvPartProg/Provider-Partnership-Email-Archive-Items/2018-07-05-eNews.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=descending#_Toc518370286.
