A House-Senate work group will begin meeting to resolve legislative differences over changes in pricing and access to Michigan's growing individual health insurance market. Observers expect the group's work to focus on establishing a system of "rate bands" that set the minimum and maximum premium an insurer could charge each month, based on a person's age and health. Currently, 1 million Michigan residents have no health insurance, often because the monthly costs are too high, and more do not have coverage because they lost workplace benefits.
