A Sacramento dentist has been indicted for running a billing scheme for false dental work.

Court documents say from 2008 to 2009, David Lewis targeted employees of UPS because their health care plan provided 100 percent coverage without any annual limits. 

In some cases, Lewis allegedly would bill Delta Health Systems for procedures that he never performed.

In other cases, he allegedly performed work on perfectly healthy teeth. The total amount of fraudulent billings was more than $1 million.
