Health insurance fraud costs the industry between $30-100 billion per year, raising premiums for all policyholders. It is defined as intentionally deceiving an insurance company to receive benefits, such as claiming expenses not incurred or hiding pre-existing conditions. Providers also commit fraud by overbilling or billing for services not rendered. Recently, fake insurance companies have also targeted consumers by offering low rates but disappearing without paying serious medical claims. To avoid fines or prison, policyholders and providers should be honest in all dealings with insurers.
