DEA Issues Immediate Suspension Order for
Rowland Heights Doctor

AUG 26 - (LOS ANGELES) – On August 25, 2010, Timothy J. Landrum, Special Agent in Charge of the Los Angeles Field Division, Drug Enforcement Administration (DEA) announced the Immediate Suspension of the DEA Certificate of Registration for Hsiu-Ying Lisa Tseng, D.O.

The action today was to suspend Dr. Tseng’s DEA Certificate of Registration in accordance with an Immediate Suspension Order and pursuant to Sections 303 and 304 of the Controlled Substances Act (CSA), Title 21, Sections 823 and 824. The DEA’s investigation of Dr. Tseng has determined that her continued registration to prescribe controlled substances is inconsistent with the public interest and constitutes an imminent danger to public health and safety.

“Prescription drug abuse continues to rise at a disturbing rate,” said Timothy J. Landrum, DEA Special Agent in Charge. “Many obtain these dangerous drugs from doctors prescribing drugs for no medical need. DEA is committed to working together with our state and local counterparts to ensure those few doctors who abuse their authority are not allowed to continue.”

A DEA investigation revealed that between September 2007 and July 2009 Dr. Tseng routinely prescribed highly abused Schedule II through IV controlled substances to drug seeking individuals, many of them between the ages of 18-26, while conducting cursory or no medical examination. The investigation revealed that many of those individuals in turn abused or diverted those drugs for illicit purposes.

Between April 2008 and July 2010, Special Agents with the DEA and Investigators from the California Medical Board conducted six undercover visits to Dr. Tseng’s office posing as patients seeking prescriptions for controlled substances. On five of the six occasions, Dr. Tseng issued prescriptions for Vicodin, Suboxone (Schedule III controlled substances) and/or Xanax (Schedule IV controlled substance) while performing a cursory or no medical examination, without taking a medical history and for no legitimate medical purpose.

Dr. Tseng will be given an opportunity for an administrative hearing, and after the hearing, the DEA Deputy Administrator will make a final decision on whether her DEA Certificate of Registration should be permanently revoked. This decision will be published in the Federal Register.

The following agencies assisted with this investigation: DEA Riverside District Office, Medical Board of California, Murrieta Police Department, Laguna Beach Police Department, Tempe Police Department, Orange County Sheriff’s Department, Los Angeles County Sheriff’s Department, Federal Bureau of Investigation, Riverside Coroner, San Bernardino Coroner, Orange County Coroner.
