HHS is the largest grant-making organization in the federal government. OIG oversees the administration of HHS grants, a key element to ensuring that grantees expend federal funds properly and efficiently. OIG takes a multidisciplinary approach to grants management oversight. We have auditors, evaluators, investigators, data analysts, and lawyers who analyze grant programs to identify vulnerabilities and offer practical solutions to improving programs. If individuals suspect a grantee is misusing funds or that grant beneficiaries are being mistreated, please contact the OIG Hotline at 1-800-HHS-TIPS (1-800-447-8477) or online at our website, oig.hhs.gov.
