A woman who was fired after a mere ten days of employment allegedly took advantage of an apparent error in the health care system, using health insurance for eight years to pay for medical treatments worth nearly a quarter of a million dollars.

A woman named Jackie Youhanian was fired from a job in Macomb County, Michigan, after less than 10 days but remained on the government-paid health insurance plan for the following eight years and proceeded to pay for treatment for cancer and other illnesses, amounting $230,000, the Associated Press reports, citing The Macomb Daily.

Macomb County Prosecutor Eric Smith filed four counts of health care fraud against the 38-year-old woman, who now lives at Prattville, Alabama.

Youhanian was removed from the payroll at the county’s Martha T. Berry Medical Facility, but not from the health care rolls; officials say this may have been a simple error in record-keeping, per the AP.

The issue is that the woman took advantage of this error; when she received insurance cards, she used them freely, according to county officials.

“This was not a one-time error, or a goof-up, or a mistake in judgment,” Smith said in a news release. ‘This was a continuing criminal scheme, spread month by month over a period of eight years.”

“Our goal, first and foremost, is to punish this criminal act and seek restitution for the losses incurred by the county. This defendant got blue-ribbon healthcare on the county's cuff. It's time for payback.”

Youhanian used her Macomb County-funded Blue Cross Blue Shield insurance to pay for care for treatment of ovarian cancer, multiple sclerosis and spinal problems, authorities say. These health problems are real and she has undergone multiple back surgeries.

She faces up to four years in prison and $50,000 in fines for the alleged fraud. Youhanian can either turn herself in to the sheriff's department or she could be extradited back to Michigan. If she is transported to Macomb County and kept to stand trial, there is a possibility that the county is required to pay additional medical bills, the Macomb Daily notes.
