A call to Medicare or going to Medicare.gov will confirm that he has an MA plan, but that's been established. Those places won't solve the mystery whether he has a Medigap, indemnity plan, or who knows what as his "supplement." Since the beneficiary in question was a stranger in a bank line, the OP will likely never know...Good point, he could be confused about what he has. I've heard Medicare beneficiaries say they wanted an advantage plan when they were actually referring to a Med Supp! In any case, a call to 800 Medicare could solve that or you can find current coverage by him logging into medicare.gov, too.
