Chesterfield Doctor Sentenced to 5 Years in Prison for Healthcare Fraud

ST. LOUIS – U.S. District Judge Henry E. Autrey on Friday sentenced a doctor who committed healthcare fraud schemes to five years in prison and ordered him to repay $2.87 million.

Dr. Stanley L. Librach, now 64, of Chesterfield, pleaded guilty in August in U.S. District Court in St. Louis to one count of conspiracy, one count of illegally prescribing controlled substances, one count of paying illegal kickbacks for referrals and one count of health care fraud. He admitted participating in healthcare fraud schemes involving both kickbacks and the illegal prescribing of controlled substances.

In one scheme, Dr. Librach, Dr. Asim Muhammad Ali, and chiropractor Jerry Dale Leech agreed to send urine samples for testing to Central Diagnostic Laboratory (CDL) in exchange for illegal kickbacks that went to business entities owned by Leech and Denis J. Mikhlin. CDL then sought reimbursement from Medicare and Medicaid for the testing. Dr. Librach also sent urine samples directly from his own separate private practice clinic to CDL. In exchange, Dr. Ali paid the wages of Dr. Librach’s employees.

In another scheme, Dr. Librach, Dr. Ali and Leech wrote prescriptions for the powerful pain medication oxycodone and other controlled substances when there was no legitimate medical purpose and while acting outside the usual course of professional conduct. Drs. Librach and Ali had not examined the patients at the pain clinics with which they were associated. They did not determine that the patients whose names appeared on prescriptions had a medical need for the controlled substances. Instead, they spent several hours one day a week pre-signing prescriptions that would be used for patients at upcoming visits. The doctors did not examine or evaluate the patients and rarely looked at patient charts before signing prescriptions. The doctors signed prescriptions for patients whose test results indicated that they were selling or otherwise diverting the controlled substances and did not address that obvious drug diversion. The conspirators knew that pharmacies would seek reimbursement for the medications from Medicare and Medicaid.

“This provider was involved in multiple elaborate healthcare fraud schemes that involved accepting kickbacks and illegally prescribing dangerous and addictive opioids for financial gain,” said Linda T. Hanley, Special Agent in Charge with the U.S. Department of Health and Human Services, Office of the Inspector General (HHS-OIG).  “HHS-OIG remains committed to working closely with our law enforcement partners to protect patients and protect the integrity of federal healthcare programs.”

Special Agent in Charge Michael A. Davis heads the Drug Enforcement Administration division that leads DEA investigations in Kansas and Missouri. "Because opioids are highly addictive, doctors have a duty to ensure they are prescribing controlled medications according to law to protect their patients’ health and safety,” said Davis.

Eleven defendants were indicted in 2020, including three doctors, their staff and purported patients. A twelfth was added in 2022. All have pleaded guilty.

Dr. Ali, 54, of Creve Coeur, pleaded guilty in May of 2024 to charges similar to the ones to which Dr. Librach pleaded. He is scheduled to be sentenced in August. Leech, 52, of Creve Coeur, pleaded guilty in 2021 to one count of conspiracy, one count of obtaining a controlled substance by fraud, one count of paying illegal kickbacks for referrals and one count of health care fraud. He is scheduled to be sentenced in September. Mikhlin, 46, of Chesterfield, was sentenced in 2021 to nine years in prison and ordered to repay $181,265.

The HHS-OIG, the DEA, the Missouri Attorney General’s Medicaid Fraud Control Unit, the Federal Bureau of Investigation, the Defense Criminal Investigative Service investigated the case. Assistant U.S. Attorneys Amy Sestric, Derek Wiseman and Jonathan Clow are prosecuting the case.
