Medicare¿s size and complexity make it vulnerable to fraud, waste, and abuse. Fraud represents intentional acts of deception with knowledge that the action or representation could result in an inappropriate gain, while abuse represents actions inconsistent with acceptable bus. or med. practices. Waste, which includes inaccurate payments for services, also occurs in the Medicare program. In 2009, the Centers for Medicare and Medicaid Services (CMS) estimated billions of dollars in improper payments in the Medicare program. This statement focuses on challenges facing CMS and selected key strategies that are particularly important to helping prevent fraud, waste, and abuse, and ultimately to reducing improper payments.
