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.
