I'm not entirely sure. Even though Medicaid is a federal system, there are state by state differences. I've heard of a "Medicaid spend down" where where someone who's income is too high for free Medicaid can actually pay a type of premium that would allow them to get Medicaid. This might apply to Phil if he's receiving Medi-Cal (California Medicaid). From my basic understanding, Phil is on SSI? That's for poor tards and disabled people who do not have enough work credits (lol Phil, work) to qualify for SSDI. SSI is also less money per month.
Government fags, feel free to correct me. This is just from what I know.
