On Thursday, Siefert was sentenced to one year and six months in prison and was ordered to pay over $1.9 million in restitution. Ehn was sentenced to two years and six months in prison and was ordered to pay over $3.7 million in restitution.

Ehn and Siefert were convicted in connection to orchestrating a scheme in which staff at a Kentucky pain clinic “billed for urine drug tests that were not medically necessary but were lucratively reimbursed by taxpayer-funded insurance providers like Medicare and Medicaid.” According to the United States Department of Justice.

Ehn was the clinic’s owner and Siefert was the clinic’s medical director.

“The defendants enriched themselves through a fraudulent urine drug testing scheme that cost Medicare, Medicaid, and commercial insurance companies over $4 million,” said Principal Deputy Assistant Attorney
