Health policies for kids are back, now that health insurers who stopped selling them after the health care overhaul passed are reopening shop, according to a recent report. Under the 2010 law, insurers were prohibited from denying coverage to children under age 19 because they had pre-existing medical conditions. Faced with the prospect of being required to insure sick kids on demand who might need lots of pricey medical care, many insurers simply stopped selling so-called child-only policies on the individual market. Since the health law was enacted, 22 states and the District of Columbia have passed laws or regulations that encouraged insurers to begin selling child-only policies again, according to a recent report at www.npr.com.
