To better protect identities and help prevent fraud and theft, the Centers for Medicare & Medicaid Services (CMS) is removing Social Security Numbers (SSN) from the Medicare identification cards. New card delivery began on April 1st, 2018 and will continue through April of 2019.
Be advised that your Blue Cross Blue Shield of Massachusetts member ID card and number will remain the same, and will not be affected by this update. Upon receiving your new Medicare card, please destroy your old one, and start using the new card immediately.
If you suspect fraud—an intentional misrepresentation or deception that an individual or entity makes knowing the representation could result in an unauthorized benefit or payment—please call Blue Cross Blue Shield of Massachusetts' Fraud Hotline at 1-800-992-4100(TTY: 711). You can call 24 hours a day, 7 days a week. To learn more about how to protect yourself and others, read the Fraud Protection flyer from the Centers for Medicare & Medicaid Services.
