A federal judge sentenced four people today for administering unnecessary medical tests on elderly Vietnamese immigrants as part of a multimillion dollar Medicare scheme.

According to the San Jose Mercury News, the four defendants, all Ukrainian immigrants, recruited hundreds of elderly Vietnamese immigrants by offering free check-ups at a bogus clinic in Milpitas. The patients’ personal account information was then used to bill Medicare for tests and procedures that either never took place, or were unnecessary.
