Individual enrollment begins October 1, 2013 for guarantee issued health insurance.
"Guarantee Issue" means you can acquire health insurance without answering any questions regarding your health history. Someone with Cancer, for example, can sign up for coverage as easily as someone with no health issues, and all applicants in the same age group, living in the same zip code will be charged the same rate for the same plan. In addition, all pre-existing conditions will be covered on day one of the coverage.
If you live in California and make between $14,856 and $44,680, you are eligible for a government subsidy to purchase your coverage.
