Three Individuals Sentenced to Prison for Fraudulently Billing Medicare and Medicaid Through Opioid Addiction Treatment Clinics in Kentucky

A Texas businessman, a Kentucky doctor, and a Kentucky woman were sentenced to prison for their roles in fraudulently billing Medicare and Kentucky Medicaid over $4.8 million through a series of addiction treatment facilities.

Today, Michael Bregenzer, 53, of Houston, Texas, was sentenced to 48 months in prison, followed by 3 years of supervised release.

In February 2026, José Alzadon, M.D., 62, of Paintsville, Kentucky, was sentenced to 60 months in prison.

In January 2026, Barbie Vanhoose, 63, of West Van Lear, Kentucky, was sentenced to 24 months in prison.

All three defendants were ordered to pay restitution of $812,881.09.

According to evidence presented at trial, Bregenzer, Alzadon, and Vanhoose orchestrated their health care fraud scheme through Kentucky Addiction Centers or KAC, which operated in Winchester, Paducah, Paintsville, and London, Kentucky. As part of his role as KAC's medical director, Alzadon prescribed Suboxone, a controlled substance that is used to treat opioid addiction. Bregenzer served as KAC's CEO and Vanhoose as KAC's billing manager.

Together, Bregenzer, Alzadon, and Vanhoose ran a scheme that falsely billed taxpayer-funded health programs like Medicare and Medicaid for medical services that were not provided or were billed as more complex and expensive services than the services patients actually received. They also conspired to falsely bill for services in the name of Alzadon's elderly father when the services either were not provided at all or were provided by Alzadon - who was unable to bill certain health plans as he was not credentialed as a provider with those plans. Bregenzer, Alzadon, and Vanhoose also conspired to use Alzadon's father's prescribing credentials, including his DEA registration number and electronic prescribing token, to prescribe Suboxone, even though Alzadon's father had not seen the patients for whom he was supposedly issuing prescriptions.

In March 2025, Bregenzer, Alzadon, and Vanhoose were each convicted at trial of conspiracy to commit health care fraud, eight counts of health care fraud, and conspiracy to distribute controlled substances using the registration number of another person. Alzadon and Vanhoose were also convicted of two counts of aggravated identity theft.

On April 7, the Department of Justice announced the creation of the National Fraud Enforcement Division (Fraud Division). The Fraud Division is laser-focused on investigating and prosecuting those who commit fraud against the American people. The Department's work to combat fraud support President Trump's Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.

The Department of Justice's Health Care Fraud Strike Force Program, currently comprised of nine strike forces operating in federal districts across the country, has charged more than 6,200 defendants who collectively billed federal health care programs and private insurers more than $45 billion since 2007. In addition, the Centers for Medicare & Medicaid Services, working in conjunction with the Office of the Inspector General for the Department of Health and Human Services, are taking steps to hold providers accountable for their involvement in health care fraud schemes.
