Learn about the functions of an Inspector General.
Office of Inspector General's (OIG) mission is to protect the integrity of Department of Health & Human Services (HHS) programs as well as the health and welfare of program beneficiaries.
Who We Are
Since its 1976 establishment, OIG has been at the forefront of the Nation's efforts to fight waste, fraud and abuse in Medicare, Medicaid and more than 100 other HHS programs.
HHS OIG is the largest inspector general's office in the Federal Government, with approximately 1,600 dedicated to combating fraud, waste and abuse and to improving the efficiency of HHS programs. A majority of OIG's resources goes toward the oversight of Medicare and Medicaid — programs that represent a significant part of the Federal budget and that affect this country's most vulnerable citizens. Our government oversight extends to programs under other HHS institutions, including the Centers for Disease Control and Prevention, National Institutes of Health, and the Food and Drug Administration.
What We Do
We carry out our mission using a multidisciplinary, collaborative approach, with each of our six components playing a vital role in government oversight.
A nationwide network of audits, investigations, and evaluations results in timely information as well as cost-saving or policy recommendations for decision-makers and the public. That network also assists in the development of cases for criminal, civil and administrative enforcement.
OIG develops and distributes resources to assist the health care industry in its efforts to comply with the Nation's fraud and abuse laws and to educate the public about fraudulent schemes so they can protect themselves and report suspicious activities.
