If you purchased the Student Health Insurance Plan offered by Blue Cross Blue Shield, you should have received your 1095b form in the mail. It was sent to the address on file with Blue Cross Blue Shield. If you have not received the form you may log into your account through the BCBS member portal and find the form there. The site will give you instructions on how to print the form.
If you have not receive the form, it is because you have not contacted BCBS to give them your social security number. BCBS needs your social security number in order to report your insurance coverage to the IRS. You will need to contact BCBS by calling 1-888-351-8283 and provide your SSN to them.
