Submit a Hotline Complaint OIG Hotline Operations accepts tips and complaints from all sources about potential fraud, waste, abuse, and mismanagement in the U.S. Department of Health and Human Services’ programs. Every report we receive is important, however, not every submission results in an investigation. Due to the high volume of complaints we receive, it is not possible to contact every complainant. However, Hotline tips are incredibly valuable, and we appreciate your efforts to help us stamp out fraud, waste, and abuse.
