For hundreds of thousands of Florida parents who can't get or can't afford health insurance, Florida has a subsidized, low-cost program called KidCare that covers children. But children's advocates complain that it's too difficult for parents to enroll their children and keep them in, and are urging lawmakers to make it easier to navigate KidCare. Simplifying the system is an effort that has bipartisan support but has failed in previous years, but the effort got a bit of new life with the emergence this week of a bill primarily aimed at helping families of children with autism and related disorders get coverage for their treatment.
