Fraud Detection Systems: Centers for Medicare and Medicaid Services Needs to Ensure More Widespread Use

摘要

GAO has designated Medicare and Medicaid as high-risk programs, in part due to their susceptibility to improper payments--estimated to be about $70 billion in fiscal year 2010. Improper payments have many causes, such as submissions of duplicate claims or fraud, waste, and abuse. As the administrator of these programs, the Centers for Medicare and Medicaid Services (CMS) is responsible for safeguarding them from loss. To integrate claims information and improve its ability to detect fraud, waste, and abuse in these programs, CMS initiated two information technology system programs: the Integrated Data Repository (IDR) and One Program Integrity (One PI). GAO was asked to (1) assess the extent to which IDR and One PI have been developed and implemented and (2) determine CMS's progress toward achieving its goals and objectives for using these systems to help detect fraud, waste, and abuse. To do so, GAO reviewed system and program management plans and other documents and compared them to key practices. GAO also interviewed program officials, analyzed system data, and reviewed reported costs and benefits.
