CMS has finished mailing the new Medicare cards to beneficiaries across the United States.
CMS states Medicare fee-for-service health care providers submitted 58% of claims with new Medicare Beneficiary Identifiers (MBIs) indicating some success with integration. They encourage providers to utilize the new MBIs for all Medicare transactions even though the former Social Security Number-based health insurance claim numbers are permissible during the transition period.
Old cards may be used through December 2019. If a Medicare beneficiary states they have not yet received a new card, instructions are providedhere .
