No asset test, just an income test if applying through an exchange. Asset test exists for other means of applying. Eligibility is as follows via an exchange:
0-100% of poverty level – Medicaid only
100-x% of poverty level – Medicaid only (if state expanded the program). Or no insurance otherwise.
x-400% of poverty level – private insurance with subsidy
400+% of poverty level – private ins, no subsidy
