New Hampshire has issued an order allowing nearly 3,000 residents with health insurance through the state's high risk pool to keep their coverage until alternatives are fully available under the federal health care overhaul law. The high risk pool serves 2,750 residents who otherwise may have trouble obtaining insurance. It was scheduled to shut down Dec. 31 because after that, insurers must issue polices without regard to health status. But given the problems with the federal government's website for purchasing plans, many people have worried that they won't be able to purchase new insurance in time to avoid interruptions in coverage. Insurance Commissioner Roger Sevigny on Friday issued an order keeping the high risk pool open until the federal marketplace is fully available.
