What do the new Medicare cards mean for other payers?
Medicaid & supplemental insurers
We’ll give State Medicaid Agencies and supplemental insurers the MBIs for Medicaid-eligible people who also have Medicare before we mail the new Medicare cards. During the transition period, we’ll process and transmit Medicare crossover claims with either the HICN or MBI.
For non-Medicare business, private payers won’t have to use the MBI. If you are a supplemental insurer, we’ll continue to use your unique numbers to identify your customers, but after the transition period, you must use the MBI for any Medicare transactions where you would have used the HICN.
