State and federal investigators have increased their efforts at curbing what they deem health care fraud. Sometimes Current Procedural Terminology (CPT) codes or the Healthcare Common Procedure Coding System (HCPCS) present confusing or ambiguous direction for classifying medical treatment or the purchase of medical equipment, and even a minute billing error could trigger an investigation. Here are some of the forms health care fraud can take:

Over billing Upcoding Unbundling Double billing Submitting a false invoice HIPAA violations Medicare and Medicaid Insurance Fraud Avoiding Obstruction of Justice Charges

Investigators often request billing records and the like to figure out to investigate possible fraud. Even if a doctor or medical equipment supplier hasn't committed fraud, they could find themselves on the wrong side of an indictment for sloppy record-keeping or destruction of records. Destroying, removing or withholding files can constitute obstruction of justice under some circumstances. As a result, a health care provider accused of fraud may be acquitted, but found guilty and imprisoned or fine for obstructing justice.
