WASHINGTON, D.C., September 24, 2005 – LAWFUEL – The Law News Network – Hogan & Hartson L.L.P. announced today that Jonathan L. Diesenhaus has joined the firm as a litigation and healthcare partner in the Washington, D.C. office.

Diesenhaus most recently served as senior trial counsel at the U.S. Department of Justice (DOJ), handling civil fraud, False Claims Act, and other healthcare fraud and abuse matters.

“Jonathan’s extensive Department of Justice experience will be invaluable to our clients, especially those in the healthcare and food and drug industries,” said Austin Mittler, practice area administrator of Hogan & Hartson’s litigation group. “Moreover, the insight Jonathan has gained from working closely with federal and state regulatory and law enforcement officials on their healthcare fraud and abuse concerns will be of great assistance to healthcare clients in their efforts to comply with the laws applicable to this ever-changing marketplace,” added Ann Vickery, practice director of the firm’s healthcare group.

Since 1998, Diesenhaus had worked in the Fraud Section of DOJ’s Civil Division, where he investigated and litigated healthcare fraud cases, including qui tam cases brought by whistleblowers. Throughout his tenure in the department, Diesenhaus handled matters regarding the Stark Law, the healthcare Antikickback Statute, and the application of the False Claims Act to unlawful marketing practices, including violations of the Food, Drug and Cosmetics Act.

Diesenhaus worked closely with the U.S. Department of Health and Human Services (HHS) Office of the Inspector General and Office of General Counsel to interpret and enforce the Antikickback Statute and the Stark Law. Recently, Diesenhaus also worked with a team assigned to coordinate the Civil Division’s Pharma Fraud Initiative. His work focused on investigation and analysis of allegations that off-label marketing and payment of kickbacks by pharmaceutical manufacturers resulted in violations of the False Claims Act.

Diesenhaus received several awards during his government tenure, including a U.S. Food and Drug Administration Commissioner’s Special Citation, two Department of Justice Civil Division Special Commendations, a Director’s Award from the Executive Office of the U.S. Attorneys, and an Inspector General’s Integrity Award from HHS.

Prior to joining the Department of Justice, Diesenhaus worked in private practice. He represented providers, manufacturers, and physicians in civil and criminal healthcare fraud and antitrust matters.

He served as a law clerk to The Honorable Sherman G. Finesilver of the U.S. District Court for the District of Colorado.

Diesenhaus received his law degree from the Boalt Hall School of Law at the University of California and his bachelor’s degree, cum laude, from the University of Colorado.
