Medicare to remove Social Security Numbers

Social Security Number Removal Initiative

What do you need to do to get ready?

The Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) requires CMS to remove Social Security Numbers (SSNs) from all Medicare cards by April 2019. A new randomly generated Medicare Beneficiary Identifier (MBI) will replace the SSN-based Health Insurance Claim Number on new Medicare cards for transactions like billing, eligibility status, and claim status. Prepare for this change by visiting the new overview and provider webpages, which include:
