About Mark

Mark Rust serves as the Chicago office managing partner and vice chair of the firm’s Management Committee. A healthcare industry veteran who is dedicated to delivering distinctly unique perspective and depth, Mark’s practice is focused on the transactional, regulatory and medical-legal issues affecting healthcare entities and provider organizations. The immediate past chair of the firm’s national Healthcare Department, Mark has practiced in or written about healthcare law in publications such as the Journal of the American Bar Association and USA Today, among many others, for more than 35 years. He is listed as a notable healthcare lawyer in Chambers USA, Top Healthcare Lawyers of Illinois, Illinois Super Lawyers and The Best Lawyers in America. Mark has represented hospitals and hospital-physician joint ventures, multi-specialty clinics, large radiology, anesthesiology and cardiology groups, medical staffs, healthcare management companies and managed care organizations, including provider-sponsored insurance companies and HMOs. He routinely is engaged to advise on mergers and acquisitions, contract formation and negotiation, and regulatory issues. In addition to federal fraud and abuse, Stark analysis and state healthcare regulation, Mark has focused on the application of ERISA pre-emption to the healthcare field. He and his firm appeared before the U.S. Supreme Court in Rush Prudential v. Moran, 536 U.S. 355 (2002), successfully arguing, for the first time, how the relationship between providers, patients, managed care and state regulation should work under the federal law known as ERISA. Mark was also counsel of record on behalf of the American Medical Association and 50 state medical societies on the same topic before the Supreme Court the following year in Kentucky v. Miller, 538 U.S. 329 (2003). Mark is also involved in the ongoing analysis of antitrust issues. For Thompson West Publishing, he regularly updates the antitrust section of The Law of Medical Practice in Illinois, Third Edition. In addition, Mark has appeared before the U.S. Congress and several state legislatures providing testimony on healthcare delivery and managed care. At his best when faced with complex problems, Mark draws upon his creativity and experience to find a clear path to resolution by providing legal advice that is both practical and actionable. Mark’s diligence, preparation and clear understanding of client objectives at the onset of representation allows him to offer advice that is not only on point, but also seeks to conserve his client’s time and resources. Mark is appreciated by clients and colleagues alike for his intelligence, skill in and understanding of healthcare law, and for his flexibility in adapting to and leveraging myriad positions and outlooks. Prior to the law, Mark began his career as an investigative reporter. Notably, he served as the former national legal affairs reporter and business editor for the American Medical News (1983-1989), which led him to his career as a healthcare lawyer. A charismatic presenter and devoted educator, Mark frequently serves as an invited guest and keynote speaker on healthcare related topics, including the challenges associated with the federal government’s inability to identify a consistent path toward regulation and reimbursement.
