A federal grand jury indicted three women with what authorities are saying is a $50 million health insurance fraud scheme. Theresa Fisher, 44 of Tustin, Vi Nguyen, 31 of Placentia and Lindsey Hardgraves, 30 of San Pedro are each charged with multiple counts of mail fraud. If convicted, the women face up to 20 years in state prison for each mail fraud count.

Authorities allege, the women worked for or on behalf of an Orange-based surgical center known under several names, Princess Cosmetic Surgery, Empire Surgical or Vista Surgical. Nguyen and Fisher worked as consultants for the center while Hardgraves was a marketer. The women are accused of offering patients free or discounted cosmetic procedures in exchange for undergoing unnecessary medical procedures such as endoscopies, cystoscopies or colonoscopies.

The alleged scheme caused more than $50 million worth of claims to insurance companies. The women have been released on bond and ordered to appear for an arraignment on July 28, 2014
