In 2020, Melsheimer was counsel for whistleblowers Dr. Mitchell Magee and Dr. Todd Dewey in a qui tam Medicare fraud case filed in the Eastern District of Texas alleging Texas Heart Hospital of the Southwest LLP and others violated the federal anti-kickback law, the physician self-referral law, and related statutes.
