Insurance fraud happens when a person makes a fake insurance claim to obtain benefits or compensation to which they are not entitled. It is often seen as a victimless crime—it’s not. It’s a cost everyone pays through increased premiums. You can play a pivotal role in stopping insurance fraud by reporting it.  Examples of fraud can involve all types of insurance—health, auto, property, and life.
