Date
The Medicare Access and CHIP Reauthorization Act (MACRA) requires CMS to remove Social Security Numbers (SSNs) from the current SSN-based Health Insurance Claim Number (HICN) and issue a new Medicare card with a Medicare Beneficiary Identification (MBI) number.
CMS has finalized mailing the new Medicare Beneficiary ID cards with the new MBI numbers to participants. Therefore, all Missouri Dual eligible Medicaid and Medicare participant have received their new cards.
All Medicare claims submitted after January 1, 2020, are required to use the new MBI number. Those claims filed with the participant’s old HICN will reject for a mismatch of DCN/MBI combination not found in the MMIS.
