Insurance companies couldn’t charge women higher rates for health coverage than men in individual plans under a bill that received initial Senate approval Monday, The Denver Post reports. Supporters of the legislation say women often are charged as much as 40 percent more than men for individual health-insurance plans. Proponents said group plans and public health programs do not have different cost structures for men and women, but individual-market plans frequently do. The bill would affect about 140,000 women, proponents said.
