If you are poor enough, you can get Medicaid to pay for your medical bills, but if you are just a little too well-off financially to qualify for Medicaid, you are out of luck.
Also, some states have programs to help children of parents who are just a little too well-off for Medicaid get medical care, but those are often underfunded and they just help children and pregnant women, not other adults.
