Unicare is BCBS, it's just marketed differently. They are both owned by Wellpoint, in some states.
BTW, a Patient Advocate is someone who writes appeals, and helps get bills paid correctly by the insurance companies. I am a Patient Advocate and there are others who do the same type of work. We usually have experience working for insurance companies, so we know how the process works internally.
