A North Hollywood woman who pleaded guilty in January to health care fraud was sentenced Monday to six years in federal prison and ordered to pay nearly $10 million restitution to Uncle Sam.

Susanna Artsruni, 46, whose Midvalley Medical Supply of Van Nuys had submitted nearly $25 million in bogus bills to Medicare, was sentenced by U.S. District Judge Margaret M. Morrow, according to the U.S. Attorney’s Office. Artsruni, who also used the names “Mary” and “Rose,”worked at a number of medical clinics in Los Angeles.

She was sentenced after pleading guilty earlier this year to one count of health care fraud and one count of money laundering. She was ordered to serve 76 months in prison and to pay $9,624,556 in restitution to Medicare.

In her plea agreement, Artsruni admitted to billing Medicare for services and supplies that were medically unnecessary and sometimes never provided. The scheme involved physician’s assistants at three Los Angeles medical clinics who signed prescriptions and orders for unnecessary tests, services and equipment. She also admitted to writing checks of more than $35,000 from the Midvalley bank account to three corporations that had no connection to the medical industry and apparently had not provided any legitimate business services to her company. The checks, she admitted, were meant to launder funds related to the welfare fraud. At the time, Artsruni was free on bond in another health care fraud case whose terms ordered her not to work at any medical facility.

A second defendant in the case, Erasmus Kotey, a physician’s assistant, has pleaded guilty and is scheduled to be sentenced Sept. 8, according to the U.S. Attorney’s Office. Charges have been filed to three others allegedly associated with the money laundering, who have pleaded not guilty for a trial expected early next year
