A dentist who lives in Arlington but practices in Alexandria has been sentenced to nearly four years in prison for health care fraud.

According to the U.S. Attorney’s Office, 43-year-old Tuan Vu, who owns Cosmetic & Family Dentistry, PLLC, pled guilty in January to committing health care fraud. Court documents show that Vu admitted the scheme took place at least from January 2007 to September 2011, when he billed dental insurance providers for services he never performed on his patients.

Because of the scheme, more than 50 private insurance providers lost more than $2 million. The federal government and the Commonwealth of Virginia also suffered losses, including more than $300,000 to the Federal Employee Health Benefits Program and the Virginia Medicaid program.

Vu was sentenced to 46 months in prison, to be followed by two years of supervised release. Additionally, he was ordered to pay a $250,000 fine and more than $2 million in restitution.
