CMS to hold open door forum about new Medicare cards
CMS will be hosting an open-door forum on September 11 to discuss the status of new Medicare cards and Medicare Beneficiary Identifiers (MBI). Beginning January 2020, Medicare will only accept claims submitted with MBIs. The updated cards are designed to offer better identity protection by replacing social security numbers with unique MBIs. The new Medicare cards were mailed out in August.
