Under the exchange, consumers will be able to choose from bronze, silver, gold, platinum and catastrophic plans that offer a range of premiums, deductibles and co-pays depending on variables such as how many doctors they want included in their network. Insurers are offering 308 plans through the exchange in Florida, according to state insurance officials.

Individuals will have to have health insurance from their employer or purchase it, and will pay a roughly $100 penalty next year if they don't. Anyone making below the poverty line won't be eligible for subsidies through the online marketplace. Federal health officials anticipate roughly 1 million Floridians will fall into a gap where they can't get health insurance because the state rejected Medicaid expansion.

Sebelius will be at Jacksonville's Sulzbacher Center at 611 East Adams Street at 1 p.m. Monday to meet with Mayor Alvin Brown and area stakeholders.
