Millions of individuals receive prescription drugs through fed. programs. The increasing cost of prescription drugs has put pressure to control drug spending on fed. programs such as the Fed. Employees Health Benefits Program (FEHBP), Medicare Part D, the VA, the DoD, and Medicaid. Prescription drug spending within the FEHBP in particular, which provides health and drug coverage to about 8 million fed. employees, retirees, and their dependents, has been a significant contributor to FEHBP cost and premium growth. This report describes approaches used by the FEHBP to control prescription drug spending and summarizes approaches used by other fed. programs. Illustrations.
