CHATTANOOGA, Tenn. — BlueCross BlueShield of Tennessee announces four medical staffing changes in the company’s government business and emerging markets (GBEM) unit. The restructure of these medical roles and responsibilities is a result of business growth and new business development.

BlueCross has tapped Bruce Taffel, M.D., to serve as chief medical officer for GBEM. He will be responsible for oversight of the development, implementation, and monitoring of the medical policy and medical management programs for government business and will be a liaison to the chief medical officer for the company’s commercial business operations. Taffel most recently served as the medical director for health informatics and quality improvement. He’s been with BlueCross since 1998.

Joseph “Chip” Thomas, M.D., will advance from the role of associate medical director to medical director of Medicaid operations where he’ll oversee medical management for the program and interface with the Bureau of TennCare on behalf of BlueCross. Chip joined BlueCross in September 2004 after serving as medical director at Unum Provident.

Making a return to BlueCross, David Moroney, M.D., will function as senior medical director of quality improvement. In this position, Moroney will work to maintain current and achieve new accreditations for all lines of business as well as enhance enterprise-wide quality improvement activities. David served as medical director for Medicaid operations before accepting a position last year with Wellpoint, one of the country’s largest publicly traded commercial health benefit companies.

Dennis Weaver, M.D., joins BlueCross as medical director for health informatics. His responsibilities will cover the development and implementation of marketing strategy for products and services developed by the company’s health intelligence group. Weaver comes to BlueCross from the position of chief medical officer and managing director of BearingPoint, a global consulting company based in McLean, Va.
