Ortiz Taps Former State Prosecutor as New Healthcare Chief
July 16, 2012

BOSTON - United States Attorney Carmen M. Ortiz announced the appointment of K. Nathaniel Yeager as Chief of the U.S. Attorney’s Health Care Fraud Unit.

Yeager, 44, joins the U.S. Attorney’s Office after serving as Chief of the Massachusetts Attorney General’s Office Medicaid Fraud Division for the last 15 months. Prior to his role as Chief, Yeager was an Assistant Attorney General working primarily health care fraud cases. From 1996 to 2008, Yeager was an Assistant District Attorney at the Middlesex District Attorney’s Office, during which time he tried dozens of criminal cases, including homicides and other serious felonies.

During the course of his career, Yeager was the lead attorney on many homicides, including the prosecution of a former Missouri radio reporter who gave his wife a lethal dose of antifreeze, then delayed taking her to a hospital for 10 hours because he wanted to collect $250,000 in life insurance. The defendant, James Keown, was convicted of the September 2004 killing. In a matter with national implications, Yeager was a member of the Attorney General’s Office team that won a significant wholesale drug pricing case at trial. In that matter, certain drug companies intentionally reported false and inflated wholesale prices, for certain types of outpatient drugs.

“As a former state prosecutor, Nat Yeager brings extensive legal and trial expertise, and a reputation for integrity and hard work,” said U.S. Attorney Ortiz. “His sound judgment and capable leadership are key, as we fulfill our commitment to the citizens of Massachusetts to provide the highest caliber of federal prosecutors.”

“Our Health Care Fraud Unit has pursued countless criminal cases against corporate defendants and led the nation in total recoveries. I look forward to continued success under the leadership of Nat Yeager,” she added.

Formerly led by AUSA Susan Winkler, Ortiz’s Healthcare Fraud Unit accounted for more than half of the nation’s total civil and criminal recoveries in healthcare fraud since 2009, recovering $8.5 billion in settlements, judgments, fines, restitution, and forfeiture under the False Claims Act and the Food, Drug and Cosmetic Act. Winkler has returned to her former position as an Assistant U.S. Attorney prosecuting health care fraud cases.
Yeager’s professional accolades include a Massachusetts Lawyers Weekly Lawyer of the Year Award; District Attorney John A. Droney Award for Dedication and Excellence of Service; and the District Attorney Thomas F. Reilly Award for Extraordinary Standard of Excellence in Professionalism and Ethical Sensitivity. Yeager earned his Juris Doctor from New England School of Law, where he was Editor-in-Chief of the New England Law Review. He received his Bachelor of Arts degree from American University.
