As a healthcare fraud investigator, you investigate possible healthcare fraud committed by a health care provider who is trying to bill for an unperformed or unnecessary service. Your duties include researching evidence and documents, interviewing the provider and patient, gathering information to review, analyzing claims, and producing reports with your final recommendations. You must conduct investigations with an unbiased view and communicate with an adjustment claim representative, law enforcement, attorneys, and the organization. A healthcare fraud investigator may handle multiple cases at once and may testify at legal proceedings if necessary. Most of these positions are with insurance companies.
