CMS reported that a data breach in May 2023 occurred with one of CMS’ contractors. As a result, about 612,000 Medicare beneficiaries were affected. CMS is contacting the affected Medicare beneficiaries to change their Medicare MBI number and offer free credit monitoring.
There are currently 47,000 patients who have received a new MBI number. When checking benefits or filing claims for your Medicare patients, if you get an “invalid member ID” notice, ask your patients for their new Medicare card(s). You can also access your Medicare Administrative Contractor’s secure internet portal to use the MBI look-up tool at https://www.cms.gov/MAC-info
