You are not eligible unless you have been without health coverage for at least the last 6 months. For example, if you have Medicare or TRICARE, you shouldn't apply. Also, if you have coverage provided by a state high risk pool or insurance coverage that may not cover a pre-existing medical condition, you shouldn't apply. If you are uninsured and have been told that you may be eligible for other coverage programs like Medicaid and the Children's Health Insurance Program, you should check out those programs first, as they may better meet your needs. If you have job-based coverage, or individual insurance coverage, you aren't eligible to apply.
