Today is the day when the temporary high-risk pool program begins for people with pre-existing conditions. If you have a pre-existing condition and haven’t been able to get coverage, this program might help you until 2014, when health insurance companies won’t be able to turn you down anymore. But depending on what state you’re in, it might be a while before your coverage can actually begin.

The new HealthCare.gov Web site has an interactive map where you can find out when your state’s program begins and when you can apply for coverage. Not all of the states’ programs are open for business as of today. Some states, like Wisconsin, New Mexico, and Oregon, are open for business today. That’s also true in the 19 states — including Texas, Virginia, and Florida — that are letting the federal government run their programs for them.

However, some of the states that are running their own risk pools aren’t ready to enroll people just yet. Pennsylvania, for example, starts taking applications on July 12. Iowa will start on July 15. Other states, including New York, California, Washington, and Colorado, will wait until August to start their programs. Illinois won’t be ready until mid-August.

If you need coverage and haven’t been able to get it through private insurance for at least six months, check out the interactive map to find out when your state program will begin and how to apply.
