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 participants 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.
This notice pertains to MO HealthNet providers who submit claims to Medicare for Missouri Dual Eligible (Medicare/Medicaid) participants, resulting in a “crossover” claim being generated to MO HealthNet for the portion Medicare does not pay. If you have questions, please contact the MO HealthNet Provider Education Unit at firstname.lastname@example.org or (573) 751-6683.
