"The Medicare Access and CHIP Reauthorization Act (MACRA) of 2015, requires us to remove Social Security Numbers (SSNs) from all Medicare cards by April 2019. A new Medicare Beneficiary Identifier (MBI) will replace the SSN-based Health Insurance Claim Number (HICN) on the new Medicare cards for Medicare transactions like billing, eligibility status, and claim status. You can find more details in our 11/1/16 SSNRI Open Door Forum slides.
We currently use an SSN-based HICN to identify people with Medicare and administer the program. We’ve used the HICN with our business partners:
- The Social Security Administration (SSA)
- The United States Railroad Retirement Board (RRB)
- State Medicaid Agencies
- Health care providers
- Health plans
Under the new system, for each person enrolled in Medicare, we’ll:
- Assign a new MBI
- Send a new Medicare card..."
