Per April 20 New York Times article, Medicare will begin to integrate a 8-year plan to replace current Medicare ID cards with new cards. The current Medicare ID card contains the beneficiary's (or spouse's) social security number and uses that number as the ID number for services.
The new ID cards will remove the SSN and replace with a new ID code.
Medicare officials have up to four years to start issuing cards with new identifiers. They have four more years to reissue cards held by current beneficiaries. They intend to replace the Social Security number with “a randomly generated Medicare beneficiary identifier,” but the details are still being worked out.
