Am I allowed to have private health insurance like BCBS while on SSI?

And do I have the option to use it instead of Medicaid? Say I am on SSI, living with my significant other and paying half the rent/food, but either they or I want to continue paying for my private health insurance. Am I allowed to do this?

Yes, you are allowed to have a private policy like BCBS. When you have private insurance that insurance will be primary and Medicaid will be secondary, picking up what BCBS doesn't pay in most cases.
