United States ex rel. Bondy v. Consumer Health Found.,
No. 00-2520 (4th Cir. 2001)

 The United States Circuit Court for the Fourth Circuit upheld the district court's dismissal of a physician's qui tam action wherein the physician alleged that the HMO at which he had previously been employed had defrauded Medicare by billing it for patient care charges that had already been reimbursed by a private insurer. The Fourth Circuit found that the district court was correct in determining that the physician failed to produce any direct evidence tending to show that the HMO was not properly preparing its cost statements. The court also held that the physician could not claim that he was inappropriately discharged as a result of his investigative activities since he had already litigated the alleged wrongful termination in a previous age discrimination lawsuit brought against the HMO.
