Definition | The Medicare HIC Number (HICN) is an identifier formerly used by SSA and CMS to identify all Medicare beneficiaries. For many beneficiaries, their SSN was a major component of their HICN. To prevent identify theft, among other reasons, HICN gradually were retired and replaced by the Medicare Beneficiary Identifier (MBI) over the course of 2018 and 2019. HICN continue to be used by Medicare for limited administrative purposes after 2019 but starting in 2020 the MBI became the primary identifier for Medicare beneficiaries. HICN consists of two components: SSN & alpha-suffix or (for Railroad IDs) prefix and ID (not always SSN based) |
