In addition, there have been several high-profile Government Accountability Office investigations of the Department of Defense.

's Consolidated Mail Outpatient Pharmacy  program. The CMOP fills continuation of therapy or refill prescriptions only. Initial prescriptions are written for veterans at one of the Veteran Administration’s health care facilities. When a refill is needed, the heath care facilities process the prescriptions. The CMOP then uploads this information from multiple facilities in its region. Once filled, the US Postal Service delivers the prescriptions. The health care facility or clinic is notified of the prescription’s completion electronically. As of 2000, the annual workload was near 50 million prescriptions. Processing and filling prescriptions took two days; three more days were required for mail delivery.

Because of congressional interest in exploring if CMOP could provide cost savings for Department of Defense beneficiaries picking up outpatient refill prescriptions from military treatment facilities, the DOD and VA conducted a pilot program in FY 2003. In its 2005 report, GAO-05-555, the Government Accountability Office Government Accountability Office
