A major crackdown on health care fraud in the Southern District of Texas has resulted in charges against nearly 50 individuals. These cases are part of a national effort by the Department of Justice to address fraudulent activities related to health care, including schemes involving the illegal distribution of controlled substances, hospice fraud, kickbacks, and other Medicare/Medicaid-related scams.
U.S. Attorney Nicholas J. Ganjei emphasized the importance of protecting Medicare funds: “Americans rely on Medicare for needed treatments and life-saving care. Those that bilk this fund to unlawfully enrich themselves are ultimately stealing from the taxpayer and damaging public confidence in our health system.” Attorney General Pamela Bondi added, “This record-setting health care fraud takedown delivers justice to criminal actors who prey upon our most vulnerable citizens and steal from hardworking American taxpayers.”
Among the largest cases is an alleged $110 million hospice fraud scheme involving Dera Ogudo and Victoria Martinez, both from Richmond. They are accused of misleading elderly patients about their enrollment in hospice services that were not necessary according to Medicare standards. In another case, Keilan Peterson and Kimberly Martinez face charges for allegedly distributing controlled substances through Houston clinics.
Additionally, David Jenson and Nestor Rafael Romero Magallanes are charged with defrauding Medicare by billing over $90 million for unneeded skin substitute products. Other notable cases include Tyneza P. Mitchell’s alleged fraudulent billing for COVID-19 services she did not provide, and Daphne Johnson’s scheme to bill Medicaid for mental health therapy services never rendered.
The nationwide operation led to charges against 324 defendants accused of participating in various fraudulent schemes totaling over $14.6 billion in intended losses and involved more than 15 million illegally diverted pills.
The investigations were conducted by multiple agencies including the Department of Health and Human Services – Office of Inspector General (OIG), FBI, Drug Enforcement Administration, among others. The prosecution involves numerous U.S. Attorneys’ Offices across different states.
As always, it is important to note that a complaint or indictment is merely an accusation; defendants remain innocent until proven guilty through due process.
