Michigan lawmakers still are working toward consensus on how to change rules guiding Michigan's health insurance market for individuals, such as whether there should be a high-risk pool to cover people who get turned down for coverage elsewhere. The state Senate passed its version of legislation, which is different from legislation approved last year by the House. The two chambers must resolve their differences before the law could be changed for the market covering people who buy their own insurance because they aren't covered by employer or government plans.
