UnitedHealth Group Inc. and Aetna Inc. have come up with new ways to use technology to reach out to customers.

UnitedHealth, Minnetonka, Minn., says its United with Me program will offer employers a system that can use demographic information, geographic information and other data to help employers tailor communications efforts and insurance programs to fit employee needs.

Aetna, Hartford, is about to add a Web tool that will give plan members facility-specific costs for about 30 common medical procedures. The company already offers physician price, quality and efficiency information.
