Michael C. Theis

Mike Theis focuses on health care fraud and abuse litigation and counseling, federal and state False Claims Act litigation, government investigations, and white collar criminal defense.

Before joining Hogan & Hartson, Mike served for eight years as an Assistant U.S. Attorney in Denver, Colorado. As the criminal health care fraud coordinator for the District of Colorado, he was responsible for supervising the district's investigations and prosecutions of health care fraud, federal anti-kickback offenses, and violations of the Food, Drug and Cosmetic Act. Mike was a member of the Economic Crimes Section where he tried several high-profile mail fraud, wire fraud, and money laundering cases, including a four-week jury trial featured as the trial demonstration case at the ABA National Institute on Health Care Fraud. His areas of responsibility included multidistrict investigations of "off-label" marketing and kickbacks in the pharmaceutical and medical device manufacturing industries, and participation in the U.S. Department of Justice (DOJ) Pharma Fraud Initiative.

While serving as the health care fraud coordinator in the Civil Division of the Colorado U.S. Attorney's Office from 1997 to 2001, Mike managed complex multiagency, multijurisdictional investigations involving hospitals, clinical laboratories, nursing facilities, and therapy providers. An experienced False Claims Act litigator, Mike often negotiated global settlements of criminal, civil, and administrative federal and state claims involving Medicare and Medicaid fraud. In 1999 he served on the DOJ working group overseeing the Hospital Pneumonia Upcoding National Initiative.

From 1988 to 1997, Mike served as a trial attorney in the civil fraud section of the DOJ. There he litigated False Claims Act and qui tam suits in federal trial and appellate courts, obtaining numerous multimillion dollar recoveries for the United States in fraud cases involving federal health care, defense procurement, and mortgage lending programs.

Mike has provided training on health care fraud, trial practice, and False Claims Act litigation to the DOJ, the Department of Health and Human Services Office of the Inspector General, and the Centers for Medicare and Medicaid Services. He has also been a frequent public speaker on the government’s health care fraud enforcement efforts.

Before joining the DOJ, Mike was a law clerk with The Honorable Clarence A. Brimmer, U.S. District Court for the District of Wyoming.
