Social Security Number Removal Initiative (SSNRI) Update

The Centers for Medicare and Medicaid Services (CMS) has a new website specifically for physicians and other providers with information on the Social Security Number Removal Initiative (SSNRI).

The Medicare Access and CHIP Reauthorization Act (MACRA) requires CMS to remove Social Security Numbers (SSNs) from Medicare beneficiary ID cards and issue new cards with a new Medicare Beneficiary Identification or MBI number.

CMS will start mailing ID cards with the new MBIs to patients beginning in April 2018. There will be a 15-month transition period beginning October 2018. During the transition period, physicians and other providers may submit a Medicare claim using either the patient’s valid and active SSN or the MBI.  Medicare will return both the SSN and the MBI on the remittance advice.

All Medicare claims submitted after January 2020 will be required to use the MBI. Those claims filed with the patient’s SSN will be rejected. 

Now is the time to look at your practice management systems and talk with your vendors to determine what changes may be required for your systems.
