Rowland Heights Doctor Accused of Los Angeles Medical Negligence and Murder

December 31, 1969

Dr. Hsiu-Ying "Lisa" Tseng has been charged with second-degree murder in the Los Angeles County overdose death of three patients. The Rowland Heights physician allegedly prescribed certain powerful drugs to patients even though they didn't need the medications. (Tseng is also charged with 20 counts of prescribing meds to people despite a lack of medical need.)

The Drug Enforcement Administration has been investigating Tseng for some time now. In 2010, authorities raided her office because they suspected she might be illegally selling prescription drugs to patients and that this practice may have resulted in at least one suicide and eight overdose deaths. The medications in those deaths had either been directly prescribed by Tseng or came through a dealer from her

At the time, the general osteopath denied any wrongdoing and she wasn't charged with any crime. However, the DEA did take away her ability to prescribe medications that were addictive, contending that Tseng had written more than 27,000 prescriptions in three year and, in many instances, had failed to conduct examinations. Now, the Osteopathic Medical Board of California is taking action to take away her license.

"Doctors must exercise care that they don't overprescribe, under prescribe, or prescribe the wrong medication to a patient," said Howard Law, PC Partner and Los Angeles Medical Malpractice Attorney Vincent Howard. "Whether the prescription-related medical negligence was accidental or an intentional way to make a profit, the medical professional should be held liable."

Unfortunately, there are doctors that their position of authority by prescribing drugs that they shouldn't be giving to patients. Just recently, the California Medical Board recently disciplined Fullerton doctor Jeffrey Dell for allegedly improperly prescribing a "dangerous" drug to a patient with whom he was sexually involved.

Dell is accused of sexual misconduct with someone that he first had sex with two months after he prescribed the drug Xanax for her. At the time, she was going through the dissolution of her marriage. According to legal documents from the board, Dell continued to prescribe "controlled substances" and "dangerous drugs" to her and lied when she submitted a written complaint about him by claiming that he'd never engaged "non-professional physical contact with her."

If you believe that medical misconduct or mistakes by your physician, nurse, or other medical professional caused you to sustain serious Los Angeles County injury or a loved one's death, you may have grounds for a civil lawsuit. Due to the nature of the work that they do, medical personnel will often have intimate access to a patient's body or mind, and it is their responsibility to provide a certain level of care and refrain from abusing that access and/or profiting from it.

"Our personal injury law firm is experienced in proving medical negligence and holding negligent parties liable via settlement or through the courts," said Los Angeles Medical Malpractice Attorney Vincent Howard.
