What Is Medicare Fraud & Abuse?

Fraud occurs when someone intentionally falsifies information or deceives Medicare. Abuse occurs when doctors or suppliers do not follow good medical practices, resulting in unnecessary costs to Medicare, improper payment, or services that are not medically necessary. A complaint about the quality of care you got from a doctor, hospital, or other provider or facility is not considered fraud or abuse.
