There should be a different Medicaid program for adults. If you qualify, contact the medicaid office and get details. If your state is ...weird...and doesn't have any medicaid for adults, then you should look at each of those health plans and compare the details like deductible, out of pocket max, docs in your area that are covered, prescription plan.. Do you need insurance because you have health problems or just to be on the safe side? The plan you pick should be appropriate to your needs. If you just want it in case you need it, go with a higher deductible plan because they are cheaper. I'd skip the dental, again unless you have existing issues, because a 6 month cleaning doesn't cost that much.
