Professional Biography

Jeff Miles is a nationally recognized authority on antitrust law, particularly antitrust issues affecting the health care sector.

Mr. Miles has limited his practice to antitrust law for more than 42 years, representing primarily hospitals, health care systems, hospital networks, physician practices and physician contracting networks. His work focuses on the antitrust ramifications of provider mergers, pre-merger and due diligence advice, joint ventures, contracting networks and other affiliations, as well as staff-privilege antitrust issues, provider and health-plan exclusionary conduct, and professional association antitrust compliance. His practice consists primarily of antitrust counseling, representing parties in investigations by the Antitrust Division, Federal Trade Commission and state attorneys general, and appellate briefs and arguments.

Prior to private practice, Mr. Miles was a trial attorney with the Antitrust Division of the U.S. Department of Justice, where most of his work related to health care antitrust enforcement. While there, he received a special commendation award from the U. S. Attorney General for serving as lead counsel in the government's first successful hospital-merger challenge. Prior to his service with the Antitrust Division, he formed and was the assistant attorney in charge of the Virginia Attorney General's Antitrust Unit. He holds undergraduate and graduate degrees in economics from Virginia Tech and a law degree from the Washington & Lee University School of Law, where he graduated with high honors and was associate editor of the Washington & Lee Law Review.

Mr. Miles currently represents a national professional association in an investigation by the U.S. Department of Justice Antitrust Division, several physician groups contemplating mergers and other types of affiliations, a hospital system in two proposed hospital affiliations, a commercial health plan divesting part of its business, and several provider groups planning clinically integrated contracting networks.  His previous work includes successfully guiding two hospitals through a Federal Trade Commission investigation, advising a clinically integrated hospital network, successfully representing a hospital system in a four-hospital merger investigated by the Federal Trade Commission, and advising a hospital contracting network in investigations by the Antitrust Division and a state attorney general.

Mr. Miles successfully represented a defendant health system; a defendant professional association; an IPA executive; a large physician practice; and hospitals. He has represented a number of physician contracting networks and merging hospitals in FTC, Antitrust Division, and state attorney general investigations resulting in consent decrees, and he obtained the first two FTC staff advisory opinions approving clinically integrated physician networks.

Mr. Miles wrote and annually updates the six-volume Health Care & Antitrust Law treatise published by Thomson Reuters/Westlaw and has written or co-written a number of other books, book chapters, law review articles, and shorter articles and papers dealing with almost every type of antitrust issue. He frequently lectures and presents papers on antitrust subjects to various bar and health care organizations. He is an adjunct professor of law at the Washington & Lee University School of Law, where he teaches the antitrust law course.
