Minnesota U.S. Senator Paul Wellstone and attorney general Mike Hatch held roundtables in Rochester, St. Paul, and Duluth today to push proposals that would give patients more abilitiy to fight their health maintenance organizations. The two Democrats say they're responding to horror stories of people who've been denied treatment or doctors who are paid not to refer patients to specialty care. However business groups contend the proposals will lead to higher health insurance costs and less coverage for people who need it.
