" DOD provides certain health care services through its TRICARE Program, which complements the health care services provided in military treatment facilities. DOD acquires these health care services through MCSCs with private sector companies. As of October 1, 2013, DOD's Defense Health Agency is responsible for awarding, administering, and overseeing TRICARE's MCSCs. Prior to this date TMA handled these duties. DOD's health care costs have more than doubled from $19 billion in fiscal year 2001 to its fiscal year 2014 budget request of more than $49 billion. Senate Report 112-173, which accompanied a version of the National Defense Authorization Act for Fiscal Year 2013, cited concerns with the growth of DOD's health care costs and identified private sector health care contracts as an area for potential savings and efficiencies. The Senate report mandated that GAO review DOD's process for acquiring TRICARE's MCSCs. This report examines: (1) TMA's acquisition process to award TRICARE's third generation MCSCs; (2) the extent to which issues were raised in the bid protests involving these MCSCs, including identifying any common themes; and (3) lessons learned from the acquisition process to award these MCSCs and how these lessons may be used in future acquisitions.
