Signage is seen at the United States Department of Justice headquarters in Washington, D.C., August 29, 2020.Andrew Kelly | ReutersThe U.S. Department of Justice on Wednesday announced criminal charges against two people in California in a scheme that allegedly made $144 million in false and fraudulent health claims to federal programs for unnecessary Covid-19 tests.The DOJ also announced criminal cases against 19 other defendants, among them doctors, a nurse, medical business executives and others, for another $8 million in false Covid-related billings to federal health programs and theft from federally-funded pandemic assistance programs. Prosecutors also allege some defendants sold fake vaccination cards and bogus coronavirus cures.The cases span nine federal court districts.”Throughout the pandemic, we have seen trusted medical professionals orchestrate and carry out egregious crimes against their patients all for financial gain,” said Luis Quesada, assistant director of the FBI’s Criminal Investigative Division.”These health care fraud abuses erode the integrity and trust patients have with those in the health care industry, particularly during a vulnerable and worrisome time for many individuals,” Quesada said.In the major California case, the owners of a clinical laboratory, Imran Shams and Lourdes Navarro, both age 63, of Glendale, were charged with a health-care fraud, kickback, and money laundering scheme that involved the fraudulent billing of over $214 million for laboratory tests.More than $125 million of those billings allegedly involved fraudulent claims for Covid and respiratory pathogen tests that “were submitted without regard to medical necessity,” according to prosecutors.”Shams and Navarro fraudulently concealed Shams’s role in the lab and his prior health care-related criminal convictions,” according to the DOJ. Shams has been barred from participating in the federal Medicare program for decades.”The indictment also alleges that Shams and Navarro paid kickbacks to marketers who obtained specimens and test orders, and laundered the proceeds of the scheme through shell companies Navarro controlled, including by making expenditures on real estate, luxury items, and personal goods and services,” the Justice Department said. In Washington state, a 53-year-old Parker, Colo., resident Robert Van Camp was accused of using blank Covid-19 vaccination cards to forge and sell hundreds of fake vaccine record cards which he sold to buyers and distributors in at least a dozen states, according to the DOJ.”Van Camp allegedly told an undercover agent that he had sold cards to ‘people that are going to the Olympics in Tokyo, three Olympians and their coach in Tokyo, Amsterdam, Hawaii, Costa Rica, Honduras,'” the DOJ said in a press release.Van Camp also allegedly told that agent, “I’ve got a company, a veterinary company, has 30 people going to Canada every f—— day, Canada back. Mexico is big. And like I said, I’m in 12 or 13 states, so until I get caught and go to jail, f— it, I’m taking the money, (laughs)! I don’t care,” the DOJ said.CNBC PoliticsRead more of CNBC’s politics coverage:Other defendants include a U.S. Postal Service worker, Lisa Hammell of Turnersville, N.J.
