Social Security Number Removal Initiative (SSNRI)

The Centers for Medicare & Medicaid Services (CMS) is issuing this Informational Bulletin to inform states about the SSNRI. Congress passed the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 (PL 114-10) on April 16, 2015. Section 501 of MACRA requires CMS to remove Social Security Numbers from Medicare ID cards and replace existing Medicare Health Insurance Claim Numbers (HICNs) with a Medicare Beneficiary Identifier (MBI). The MBI will be a randomly generated identifier that will not include a social security number or any personally identifiable information (PII). This step is being taken to minimize the risk of identity theft for Medicare beneficiaries and reduce opportunities for fraud. To comply with this statutory requirement, starting in early 2018, CMS will issue new Medicare cards with an MBI to approximately 60 million Medicare beneficiaries, including Dual Eligibles. A HICN will still be assigned to each Medicare beneficiary will still be used for internal data exchanges between CMS and the states, but the new MBI must be used in all interactions with the beneficiary, the provider community and all external partners.

In order for states to be fully compliant with this legislation and to continue critical data exchanges with CMS, state Medicaid business processes and systems must be examined and necessary changes identified, developed, tested and implemented prior to CMS assigning MBIs and distributing the new Medicare ID cards. To ensure a smooth implementation for the states, CMS has formed a bi-weekly All-State SSNRI Forum call which includes representatives from the Center for Medicare (CM), CMCS, each CMS Regional Office, and every state, territory and the District of Columbia. These calls provide CMS the opportunity to promptly communicate important guidance and updates to the state Medicaid agencies (SMAs) and for SMAs and their invited key stakeholders to ask questions, share information and facilitate coordination.
