You must give us a social security number (SSN) for every family member who is applying for MassHealth and who has been issued an SSN. However, you do not need to give us an SSN to get MassHealth Limited, Children's Medical Security Plan (CMSP), Healthy Start, or Health Safety Net. MassHealth may require you to give us the SSN, if you can get it, of any person not applying who has or can get health insurance that covers you or any member of your family.

MassHealth will use your SSN to check information you have given us. We will also use it to detect fraud, see if anyone is getting duplicate benefits, or see if others (a "third party") should be paying for services. MassHealth may match your SSN or the SSN of anyone in your family who is living with you. If MassHealth pays part of your health-insurance premiums, we may add your SSN or the SSN of the policyholder in your family to the State Comptroller's vendor file. You or the policyholder in your family must have a valid SSN before you can get a payment from MassHealth.

SSN files may be matched with the files of agencies, such as: the Internal Revenue Service, Social Security Administration, Alien Verification Information System, Centers for Medicare & Medicaid Services, Registry of Motor Vehicles, Department of Revenue, Department of Transitional Assistance, Department of Industrial Accidents, Division of Unemployment Assistance, Department of Veteran's Services, Human Resource Division, Bureau of Special Investigations, and the Department of Public Health's Bureau of Vital Statistics. Files may also be matched with social service agencies in this state and other states, and computer files of banks and other financial institutions, insurance companies, employers, and managed-care organizations.
