The Florida Department of Health has become the latest arm of state government to distance itself from the federal Affordable Care Act. It has ordered county health units not to allow outreach workers called Navigators onto their property to help uninsured people sign up for subsidized health coverage. The order from C. Meade Grigg, deputy DOH secretary for statewide services, went out late Monday to the 60 local health department directors around the state. He wrote that the staff may accept informational materials from the Navigators to hand out upon request.
