I agree with Durhamlad.
Also, depending on the state to which you are going, and your income, you may also be eligible for Medicaid (which is the state-level program for those who have little to no actual income). While technically a federal program, Medicaid is devolved to the various states and so the coverage and eligibility particulars vary wildly.
I would note that the traditionally "highly conservative" states, such as Texas and those in the deep South, have very little available to an otherwise healthy adult. Some of the "progressive" states (NY, NJ, MA, etc) have more favorable programs and allow an adult who is not disabled (and, thus, qualifies on those grounds) to "buy in" to the state programs if they are otherwise ineligible due to having too high of an income or resources. These programs basically provide preventative care and will keep you from having a ridiculous bill if you are hospitalized.
It's something to consider until you have employment, which will typically offer health insurance as a "perk". Again, it's different in each state, so you'd have to do some homework. I don't believe you can sign up for any of them until you actually are living in the specific state (signed lease or other documents to prove you are a state resident.)
Good luck!
